[0002] This patent application claims priority to U.S. non-provisional patent application No. 17 / 804,747, filed on May 31, 2022, entitled “REPEATER MEASUREMENT GAP CONFIGURATION” and assigned to the assignee of this application. The disclosure of the prior application is considered a part of this patent application and is incorporated by reference into this patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for repeater measurement gap configuration. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as a user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, among other examples).

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, using CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation, so as to better support mobile broadband Internet access. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0030] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of protection of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method implemented using other structures, functions, or structures and functions in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0031] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0032] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).

[0033] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0034] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. For example, the network node 110 may include an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks, using any suitable transport network.

[0035] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown in , network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0036] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with the network node 110). In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions but not the other. In this way, a single device may include more than one base station.

[0037] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communications between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0038] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0039] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0040] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station and / or a subscriber unit. UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node and / or any other suitable device configured to communicate via a wireless or wired medium.

[0041] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0042] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0043] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using network node 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0044] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0045] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz–24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0046] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0047] In some aspects, the network node 110 (e.g., a relay network node) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may obtain a measurement gap configuration indicating a measurement gap to be used by the relay network node to perform measurements; receive a downlink signal from a transmitter network node; and send the downlink signal to a user equipment (UE) based at least in part on receiving the downlink signal during the measurement gap. The downlink signal may include a digital or analog downlink signal. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0048] In some aspects, the network node 110 (e.g., a transmitter network node) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send a first measurement gap configuration to a relay network node indicating a first measurement gap to be used by the relay network node to perform measurements; send a second measurement gap configuration to a user equipment (UE) served by the relay network node indicating a second measurement gap to be used by the UE to perform measurements and at least partially overlaps with the first measurement gap; and receive from the UE a measurement report associated with a downlink signal sent by the relay network node to the UE during a portion of the second measurement gap that overlaps with the first measurement gap. The downlink signal may include a digital or analog downlink signal. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0049] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0050] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a user equipment (UE) 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0051] At the network node 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modulators) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0052] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0053] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0054] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0055] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figures 6 to 11 ) or any aspect of any of the methods described herein.

[0056] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232 shown as DEMOD), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 6 to 11 ) or any aspect of any of the methods described herein.

[0057] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in the may perform one or more techniques associated with relay measurement gap configuration, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 8 The process of 800 Fig. 9 900 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, conversion and / or interpretation), may cause the one or more processors, UE 120 and / or network node 110 to perform or direct, for example, Figure 8 The process of 800 Fig. 9 The process 900 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0058] In some aspects, the network node 110 (e.g., a relay network node) includes: a component for obtaining a measurement gap configuration indicating a measurement gap to be used by the relay network node to perform measurements (e.g., using the antenna 234, the modem 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, etc.); a component for receiving a downlink signal from a transmitter network node (e.g., using the antenna 234, the modem 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, etc.); and / or a component for sending a downlink signal to a UE based at least in part on receiving the downlink signal during the measurement gap (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the memory 242, etc.). In some aspects, means for a relay network node to perform operations described herein may include, for example, one or more of a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0059] In some aspects, the network node 110 described above may receive a measurement gap configuration from another network node having similar components as the network node 110, but such a network node having similar hardware components may have similar or different functionality. In one example, a network node similar to the network node 110 may terminate the Uu interface of the network node 110 and configure the measurement gap to the network node 110. Such a similar network node (e.g., a transmitter network node) includes: means for sending a first measurement gap configuration to a relay network node indicating a first measurement gap to be used by the relay network node to perform measurements (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the memory 242, etc.); means for sending a second measurement gap configuration to a user equipment (UE) served by the relay network node indicating a second measurement gap to be used by the UE to perform measurements and at least partially overlapping with the first measurement gap (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the memory 242, etc.); and / or means for receiving, from the UE, a measurement report associated with a downlink signal sent by the relay network node to the UE during a portion of the second measurement gap that overlaps with the first measurement gap (e.g., using the antenna 234, the modem 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, etc.). In some aspects, means for a transmitter network node to perform operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0060] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0061] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 Different than described.

[0062] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0063] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0064] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0065] Figure 33 is a diagram illustrating an example decomposed base station architecture 300 according to the present disclosure. The decomposed base station architecture 300 may include a CU 310, which may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed control units (such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0066] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of these units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, and the wireless interface may include a receiver, a transmitter, or a transceiver (such as an RF transceiver), which is configured to receive signals or send signals to one or more of the other units via a wireless transmission medium, or both.

[0067] In some aspects, CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by CU 310. CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface such as an E1 interface. As needed, CU 310 may be implemented to communicate with DU 330 for network control and signaling.

[0068] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partition such as that defined by 3GPP. In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0069] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions based on functional splits (e.g., functional splits defined by 3GPP) such as lower layer functional splits, or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.

[0070] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN, such as an open eNB (O-eNB) 311, via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0071] The non-RT RIC 315 may be configured to include logic functions that implement non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that implement near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0072] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to adjust RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0073] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0074] Figure 4 4 is a diagram illustrating an example 400 of physical channels and reference signals in a wireless network according to the present disclosure. Figure 4 As shown, a downlink channel and a downlink reference signal may carry information from the network node 110 to the UE 120 , and an uplink channel and an uplink reference signal may carry information from the UE 120 to the network node 110 .

[0075] As shown, the downlink channel may include a physical downlink control channel (PDCCH) carrying downlink control information (DCI), a physical downlink shared channel (PDSCH) carrying downlink data, or a physical broadcast channel (PBCH) carrying system information, etc. In some aspects, PDSCH communication may be scheduled by PDCCH communication. As further shown, the uplink channel may include a physical uplink control channel (PUCCH) carrying uplink control information (UCI), a physical uplink shared channel (PUSCH) carrying uplink data, or a physical random access channel (PRACH) for initial network access, etc. In some aspects, UE 120 may send confirmation (ACK) or negative confirmation (NACK) feedback (e.g., ACK / NACK feedback or ACK / NACK information) in the UCI on PUCCH and / or PUSCH.

[0076] As further shown in the figure, the downlink reference signal may include a synchronization signal block (SSB), a channel state information (CSI) reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS) or a phase tracking reference signal (PTRS), etc. As also shown in the figure, the uplink reference signal may include a sounding reference signal (SRS), a DMRS, or a PTRS, etc.

[0077] The SSB may carry information used for initial network acquisition and synchronization, such as a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a PBCH, and a PBCH DMRS. The SSB is sometimes referred to as a synchronization signal / PBCH (SS / PBCH) block. In some aspects, the network node 110 may send multiple SSBs on multiple corresponding beams, and the SSBs may be used for beam selection.

[0078] The CSI-RS may carry information for downlink channel estimation (e.g., downlink CSI acquisition), which may be used for scheduling, link adaptation, or beam management, etc. The network node 110 may configure a CSI-RS set for the UE 120, and the UE 120 may measure the configured CSI-RS set. Based at least in part on these measurements, the UE 120 may perform channel estimation and may report channel estimation parameters to the network node 110 (e.g., in a CSI report), such as a channel quality indicator (CQI), a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI), a layer indicator (LI), a rank indicator (RI), or a reference signal received power (RSRP), among other examples. The network node 110 can use the CSI reports to select transmission parameters for downlink communications to the UE 120, such as the number of transmission layers (e.g., rank), a precoding matrix (e.g., a precoder), a modulation and coding scheme (MCS), or to refine the downlink beams (e.g., using a beam refinement procedure or a beam management procedure), among other examples.

[0079] DMRS can carry information used to estimate the radio channel to demodulate the associated physical channel (e.g., PDCCH, PDSCH, PBCH, PUCCH, or PUSCH). The design and mapping of DMRS can be specific to the physical channel that the DMRS is used to estimate. DMRS is UE-specific, can be beamformed, can be restricted to scheduled resources (e.g., instead of being sent over a wideband), and can be sent only when necessary. As shown, DMRS is used for both downlink and uplink communications.

[0080] PTRS can carry information for compensating for oscillator phase noise. Typically, phase noise increases with the increase of the oscillator carrier frequency. Therefore, PTRS can be used at high carrier frequencies (such as millimeter wave frequencies) to mitigate phase noise. PTRS can be used to track the phase of the local oscillator and to achieve suppression of phase noise and common phase error (CPE). As shown, PTRS is used for both downlink communications (e.g., on PDSCH) and uplink communications (e.g., on PUSCH).

[0081] The PRS may carry information for enabling timing or ranging measurements of the UE 120 based on signals sent by the network node 110 to improve observed time difference of arrival (OTDOA) positioning performance. For example, the PRS may be a pseudo-random quadrature phase shift keying (QPSK) sequence mapped in a diagonal pattern with a frequency offset and a time offset to avoid collisions with cell-specific reference signals and control channels (e.g., PDCCH). In general, the PRS may be designed to improve the detectability of the UE 120, which may need to detect downlink signals from multiple neighboring network nodes in order to perform OTDOA-based positioning. Therefore, the UE 120 may receive the PRS from multiple cells (e.g., a reference cell and one or more neighboring cells), and may report a reference signal time difference (RSTD) based on the OTDOA measurements associated with the PRS received from the multiple cells. In some aspects, the network node 110 may then calculate the position of the UE 120 based on the RSTD measurements reported by the UE 120.

[0082] The SRS may carry information for uplink channel estimation, which may be used for scheduling, link adaptation, pre-decoder selection, or beam management, etc. The network node 110 may configure one or more SRS resource sets for the UE 120, and the UE 120 may send the SRS on the configured SRS resource sets. The SRS resource sets may have configured usages, such as uplink CSI acquisition, downlink CSI acquisition for reciprocity-based operation, uplink beam management, etc. The network node 110 may measure the SRS, may perform channel estimation based at least in part on these measurements, and may use the SRS measurements to configure communications with the UE 120.

[0083] In some cases, network node 110 or UE 120 may perform one or more measurements based at least in part on the reference signal during a measurement gap. A measurement gap may correspond to a time period during which network node 110 or UE 120 may perform measurements based at least in part on one or more reference signals. As described herein, a measurement gap for network node 110 may overlap (or partially overlap) with a measurement gap for UE 120.

[0084] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0085] Figure 55 is a diagram illustrating an example 500 of a handover performed by a relay network node according to the present disclosure. The relay network node 505 may communicate with a first cell 510 (cell 1) and a second cell 515 (cell 2). The relay network node 505, the first cell 510, and / or the second cell 515 may include some or all of the features of the CU 310, DU 330, and / or RU 340 described herein.

[0086] In some cases, the UE 120 may communicate with the first cell 510 and / or the second cell 515 via the relay network node 505. For example, the relay network node 505 may receive information from the first cell 510 and / or the second cell 515, and may send (e.g., forward or relay) the information to the UE 120. Additionally or alternatively, the relay network node 505 may receive information from the UE 120, and may send information to the first cell 510 and / or the second cell 515. In some cases, the information may be a communication or may include a communication. For example, the relay network node 505 may have an existing connection to the first cell 510, and may send a communication to the first cell 510 and / or receive a communication from the first cell 510. In some cases, the information may be a reference signal, or may include a reference signal, such as one or more of the reference signals described herein. For example, the relay network node 505 may receive one or more reference signals from the first cell 510 and / or the second cell 515 regardless of whether the relay network node 505 has an existing connection to the first cell 510 or the second cell 515 .

[0087] In some cases, the relay network node 505 may perform a handover from the first cell 510 to the second cell 515. For example, the relay network node 505 may be located in the coverage area of ​​the first cell 510 and may be connected to the first cell 510 at time T. The relay network node 505 may move from the coverage area of ​​the first cell 510 to the coverage area of ​​the second cell 515. The relay network node 505 may perform a handover from the first cell 510 to the second cell 515 and may be connected to the second cell 515 at time T+Δ. However, after performing the handover from the first cell 510 to the second cell 515, the relay network node 505 may no longer send information between the first cell 510 and the UE 120. This may cause the UE 120 to be disconnected from the first cell 510 and, in some cases, may cause the UE 120 to enter a radio link failure (RLF) state.

[0088] In some cases, UE 120 may receive a measurement configuration indicating a measurement gap for UE 120 to perform measurements (e.g., reference signal measurements). Additionally, relay network node 505 may receive a measurement configuration indicating a measurement gap for relay network node 505 to perform measurements. The measurement gap of UE 120 may not be aligned with the measurement gap of relay network node 505. In some cases, relay network node 505 may forward signaling information to UE 120 based on instructions from first cell 510 during a time within the measurement gap of UE 120 but outside the measurement gap of relay network node 505. UE 120 may use the signaling information received from first cell 510 (via relay network node 505) to perform beam adjustment and reference signal measurements within the measurement gap of UE 120. However, since the measurement gaps of UE 120 are not aligned with the measurement gaps of relay network node 505, the measurements performed by UE 120 may not be the same as the measurements performed by relay network node 505. This may cause relay network node 505 (e.g., based on instructions from first cell 510) to perform beam adjustment that is not aligned with the conditions at relay network node 505. For example, relay network node 505 may perform erroneous beam adjustment that causes relay network node 505 to receive noise or receive signaling from another cell. In this case, relay network node 505 and UE 120 may not be able to accurately perform a handover from first cell 510 to second cell 515.

[0089] Techniques and apparatus for relay measurement gap configuration are described herein. In some aspects, a relay network node may obtain a measurement gap configuration indicating a measurement gap to be used by the relay network node to perform measurements such as reference signal measurements. The relay network node may receive a downlink signal from a transmitter network node. The relay network node may send (e.g., forward or relay) a downlink signal to a UE based at least in part on receiving the downlink signal during the measurement gap. In some aspects, the measurement gap configuration may be an SSB measurement transmission configuration indicating a measurement window within the measurement gap, and the downlink signal may be an SSB signal. In this case, the relay network node 505 may send the SSB signal based at least in part on receiving the SSB signal within the measurement window.

[0090] As described above, the measurement gap of the relay network node may not be aligned with the measurement gap of the UE. The relay network node may forward signaling information to the UE based on instructions from a cell (e.g., a transmitter network node) during a time period within the measurement gap of the UE but outside the measurement gap of the relay network node. This may cause the relay network node (e.g., based on instructions from the cell) to perform beam adjustment that is not aligned with the conditions at the relay network node. Using the techniques and devices described herein, the relay network node may receive a measurement gap configuration including a measurement gap aligned with the measurement gap of the UE. The relay network node may send a downlink signal to the UE based at least in part on receiving a downlink signal within the measurement gap of the relay network node. The relay network node and the UE may use the downlink signal to perform measurements within the corresponding measurement gap. The measurements performed within the measurement gap may, for example, be used for beam adjustment performed by the relay network node and / or the UE or for initiating a handover procedure, etc. In some cases, measurements performed within the measurement gaps may be used by the relay network node for mobility purposes such as for cell mobility and beam mobility, and may be reported to the network via measurement reports.

[0091] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0092] Figure 6 600 is a diagram illustrating an example of a relay measurement gap configuration according to the present disclosure. The relay network node 505 may communicate with the UE 120 and with the transmitter network node 605. The transmitter network node 605 may include some or all of the features of the first cell 510, the second cell 515, the CU 310, the DU 330, and / or the RU 340.

[0093] As shown in conjunction with reference numeral 610, the relay network node 505 may obtain a measurement gap configuration indicating a measurement gap to be used by the relay network node 505. In some aspects, the transmitter network node 605 may send and the relay network node 505 may receive the measurement gap configuration. For example, the transmitter network node 605 may send an RRC message, a medium access control (MAC) message (such as a MAC control element (MAC-CE)), or a DCI including the measurement gap configuration. In some aspects, the relay network node 505 may receive the measurement gap configuration from another device, such as another transmitter network node. In some aspects, the relay network node 505 may be configured (e.g., pre-configured) with the measurement gap configuration.

[0094] In some aspects, a measurement gap of the network node 110 may indicate a time period during which the network node 110 may perform measurements based at least in part on one or more reference signals. For example, the network node 110 may perform measurements for detecting the strength of a signal, measuring channel quality, or performing beam adjustment, etc. A measurement gap of the network node 110 may be a time period during which the network node 110 is not sending or receiving other communications. In some aspects, the measurement gap indicated in the measurement gap configuration may be periodic (e.g., may be repeated according to an interval). In some aspects, the measurement gap configuration may indicate a measurement gap offset, a measurement gap repetition period (e.g., measurement gap periodicity), and / or a measurement gap length (e.g., duration of the measurement gap), etc. In some aspects, the measurement gap may be calculated using a system frame number (SFN) and / or subframe of a reference cell (e.g., a serving cell). In some examples, the measurement gap configuration may apply to all measurements. In other examples, the measurement gap configuration may apply only to certain measurements, such as measurements associated with a frequency band. In some aspects, the measurement gap configuration may be a UE configuration. For example, the relay network node 110 may have UE functionality that enables the relay network node 110 to receive side control information or perform UE mobility procedures, and the like.

[0095] In some aspects, a measurement gap associated with the network node 110 may overlap (or partially overlap) with a measurement gap associated with the UE 120. In some aspects, the network node 110 and / or the UE 120 may be configured with multiple measurement gap configurations. In this case, a measurement gap of a selected measurement gap configuration associated with the network node 110 may overlap (or partially overlap) with a measurement gap of a selected measurement gap configuration associated with the UE 120. In some aspects, the measurement gap configuration may be an SSB Measurement Transmission Configuration (SMTC) indicating a measurement window within the measurement gap.

[0096] As shown in conjunction with reference numeral 615, the transmitter network node 605 may transmit and the relay network node 505 may receive a downlink signal. In some aspects, the downlink signal may be a reference signal, such as SSB, CSI-RS, DMRS, or PTRS, etc. As described above, the measurement gap configuration may be an SMTC. In this case, the downlink signal may be an SSB signal.

[0097] As shown in conjunction with reference numeral 620, the relay network node 505 may send and the UE 120 may receive the downlink signal based at least in part on receiving the downlink signal during the measurement gap. For example, the relay network node 505 may send the downlink signal to the UE 120 based at least in part on receiving the downlink signal during the measurement gap. Alternatively, the relay network node 505 may not send the downlink signal to the UE 120 based at least in part on receiving the downlink signal outside the measurement gap. In some aspects, the measurement gap configuration may be an SMTC indicating a measurement window within the measurement gap, and the downlink signal may be an SSB signal. In this case, the relay network node may send the SSB signal to the UE 120 based at least in part on receiving the SSB signal during the measurement window.

[0098] In some aspects, sending the downlink signal may include forwarding or relaying the downlink signal from the transmitter network node 605 to the UE 120. In some aspects, the relay network node 505 may amplify the downlink signal before sending the downlink signal. For example, the relay network node 505 may generate the amplified downlink signal based at least in part on multiplying the downlink signal by an amplification factor. In this case, sending the downlink signal may include sending the amplified downlink signal. In some aspects, the relay network node 505 may send the downlink signal to the UE 120 via an access interface associated with the relay network node 505. In conjunction with Figure 7 Describe additional details about the feature.

[0099] In some aspects, the relay network node 505 may receive an indication (e.g., an instruction) to use the communication resources to send a downlink signal. The communication resources may overlap with the measurement gap. In this case, the relay network node 505 may determine not to send the downlink signal. For example, the relay network node 505 may suspend sending the downlink signal during the measurement gap based at least in part on the communication resources overlapping with the measurement gap (or multiple measurement gaps) of the measurement gap configuration.

[0100] In some aspects, the relay network node 505 may receive an indication to use the communication resource to send a downlink signal. The communication resource may overlap with the measurement gap. In this case, the relay network node 505 may prioritize the transmission of the downlink signal. For example, the relay network node 505 may perform the transmission of the downlink signal during the measurement gap. Additionally or alternatively, the relay network node 505 may send the downlink signal before sending or receiving other signals based at least in part on the communication resource overlapping with the measurement gap.

[0101] In some aspects, the relay network node 505 may receive an indication of whether to send a downlink signal within the measurement gap. For example, the indication may indicate one or more conditions for whether to send a downlink signal within the measurement gap. The indication of whether to send a downlink signal within the measurement gap may be received from the transmitter network node 605. The relay network node 505 may send a downlink signal based at least in part on the indication (as described above). In some aspects, receiving the indication may include receiving an RRC message, MAC-CE, or DCI including the indication.

[0102] In some aspects, the indication may indicate the measurement gap configuration or multiple measurement gap configurations, such as all measurement gap configurations associated with the relay network node 505. In this case, the relay network node 505 may send the downlink signal based at least in part on the relay network node 505 receiving the downlink signal according to the measurement gap configuration or multiple measurement gap configurations.

[0103] In some aspects, the indication may indicate one or more measurement gaps in the plurality of measurement gaps associated with the measurement gap configuration. In this case, the relay network node 505 may send the downlink signal based at least in part on receiving the downlink signal during the one or more measurement gaps in the plurality of measurement gaps associated with the measurement gap configuration.

[0104] In some aspects, the indication may indicate a frequency band (e.g., a frequency range or a frequency carrier). In this case, the relay network node 505 may send a downlink signal based at least in part on determining an association between the measurement gap configuration and the frequency band. For example, the relay network node 505 may send a downlink signal based at least in part on the measurement gap of the measurement gap configuration overlapping the frequency band.

[0105] In some aspects, the relay network node 505 may adapt (e.g., adjust) a bandwidth for sending a downlink signal based at least in part on whether the sending of the downlink signal will overlap with the measurement gap. For example, the relay network node 505 may adapt a wider bandwidth for sending the downlink signal based at least in part on determining that the downlink signal will be sent during the measurement gap. In some aspects, the relay network node 505 may adapt an access beam configuration of the relay network node 505 based at least in part on whether the sending of the downlink signal will overlap with the measurement gap. For example, the relay network node 505 may adapt a wider access beam configuration within the measurement gap bandwidth based at least in part on determining that the downlink signal will be sent during the measurement gap.

[0106] In some aspects, the relay network node 505 may receive another measurement gap configuration (e.g., a second measurement gap configuration). The other measurement gap configuration may indicate another measurement gap. The other measurement gap may overlap with the measurement gap. In this case, the relay network node 505 may adapt the bandwidth for transmitting the downlink signal based at least in part on whether the relay network node 505 initiates the transmission of the downlink signal during the measurement gap or during another measurement gap. For example, the relay network node 505 may adapt the wider bandwidth based at least in part on whether the relay network node 505 initiates the transmission of the downlink signal during the measurement gap or during another measurement gap.

[0107] In some aspects, the relay network node 505 may receive an indication of an access beam configuration or a forward beam configuration for sending a downlink signal within a measurement gap. In this case, the relay network node 505 may send a downlink signal within the measurement gap based at least in part on the access beam configuration or the forward beam configuration. In some aspects, the indication of the access beam configuration or the forward beam configuration may include an indication of a measurement gap configuration, a plurality of measurement gap configurations, or one or more measurement gaps indicated by the measurement gap configuration. In some aspects, the indication of the access beam configuration or the forward beam configuration may indicate one or more recommended beams and / or one or more restricted beams for access beam or forward beam transmission. In some aspects, receiving an indication of the access beam configuration or the forward beam configuration may include receiving an RRC message, MAC-CE, or DCI including the access beam configuration or the forward beam configuration.

[0108] In some aspects, the relay network node 505 may receive another downlink signal in another measurement gap associated with another measurement gap configuration. The another downlink signal received in the another measurement gap may be received before the downlink signal received in the measurement gap. For example, the relay network node 505 may receive the another downlink signal during the another measurement gap at a first time, and may receive the downlink signal during the measurement gap at a second time later than the first time. In some aspects, the relay network node 505 may receive another measurement gap configuration from the transmitter network node 605. For example, the relay network node 505 may receive an RRC message, MAC-CE, or DCI including an indication of another measurement gap configuration from the transmitter network node 605.

[0109] In some aspects, the relay network node 505 may perform a measurement (or multiple measurements) associated with another downlink signal, and may send the downlink signal in the measurement gap based at least in part on the measurement of the other reference signal satisfying the measurement condition. For example, the relay network node may send the downlink signal in the measurement gap based at least in part on the other reference signal satisfying the measurement condition (such as having a measurement above a measurement threshold in one or more directions). Alternatively, the relay network node may not send the downlink signal in the measurement gap based at least in part on the other reference signal not satisfying the measurement condition (such as having a measurement not above a measurement threshold in one or more directions).

[0110] In some aspects, the relay network node 505 may perform one or more measurements associated with another downlink signal and may send an indication of the one or more measurements to the transmitter network node 605. For example, the relay network node 505 may send a measurement report including an indication of the one or more measurements. The transmitter network node 605 may receive the measurement report and may determine whether the one or more measurements included in the measurement report satisfy one or more measurement conditions. Based on the one or more measurements in the measurement report satisfying the one or more measurement conditions, the transmitter network node 605 may send an indication for the relay network node 505 to send a downlink signal in a measurement gap. The relay network node 505 may send a downlink signal in a measurement gap based at least in part on receiving the indication from the transmitter network node 605.

[0111] In some aspects, the relay network node 505 may be an integrated access and backhaul (IAB) node. For example, the relay network node 505 may be an IAB node, and the transmitter network node 605 may be an IAB donor or parent IAB node. The IAB node may be configured to relay information or data from the IAB donor to a UE such as UE 120.

[0112] As described herein, in some cases, the measurement gaps of the relay network node 505 may not be aligned with the measurement gaps of the UE 120. The relay network node 505 may forward the signaling information to the UE 120 based on the instruction from the transmitter network node 605 during a time within the measurement gap of the UE 120 but outside the measurement gap of the relay network node 505. This may cause the relay network node 505 to perform beam adjustment that is not aligned with the conditions at the relay network node 505. Using the techniques and apparatus described herein, the relay network node 505 may receive a measurement gap configuration including a measurement gap aligned with the measurement gap of the UE 120. The relay network node 505 may send a downlink signal to the UE 120 based at least in part on receiving the downlink signal within the measurement gap of the relay network node 505. The relay network node 505 and the UE 120 may use the downlink signal to perform measurements within the respective measurement gaps. The measurements performed within the measurement gaps may be used, for example, for beam adjustment by the relay network node 505 and / or the UE 120 or for initiating a handover procedure, among other things.

[0113] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0114] Figure 77 is a diagram illustrating an example 700 of a timing diagram of a measurement gap configuration according to the present disclosure. The relay network node 505 may communicate with the first cell 510 and / or the second cell 515 via a network controlled relay (NCR) interface such as NCR-UE 705. The NCR-UE 705 may be used, for example, to receive control information, perform beam management (e.g., on a fronthaul interface), perform mobility operations, or perform other UE-related functionality, etc. The relay network node 505 may communicate with the UE 120 via an amplify and forward (A&F) interface such as A&F 710. As indicated by reference numeral 715, the relay network node 505 may use the NCR-UE 705 to detect an SSB 720 from the second cell 515. As indicated by reference numeral 725, the relay network node 505 may use the A&F 710 to send an indication of the SSB to the UE 120. The indication of the SSB may be received by the UE 120 using the SMTC 730 of the UE 120. As shown by reference numeral 735, the relay network node 505 may detect the SSB 745 from the second cell 515. As shown by reference numeral 740, the relay network node 505 may use the A&F 710 to send the indication of the SSB to the UE 120. The indication of the SSB may be received by the UE 120 using the SMTC 750 of the UE 120. In some aspects, the SMTC 730 and the SMTC 750 may correspond to different measurement windows associated with the SMTC of the UE 120. As shown, the SMTC associated with the relay network node 505 may be aligned with the SMTC associated with the UE 120 (e.g., may overlap in time with the SMTC). As shown by reference numeral 760, the relay network node 505 may receive a downlink (DL) signal 755 from the first cell 510 via the NCR-UE 705. As shown by reference numeral 765, the UE 120 may receive a DL signal from the relay network node 505 via the A&F 710. The downlink signal may be, for example, data traffic or control traffic associated with the UE. As shown by reference numeral 775, the relay network node 505 may receive an uplink (UL) signal 770 from the UE 120 via the A&F 710. As shown by reference numeral 780, the first cell 510 may receive an indication of the UL signal from the relay network node 505 via the NCR-UE 705. In some aspects, the indication of the uplink signal may include a measurement based at least in part on the downlink signal, such as a measurement associated with the SSB signal.
