Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates generally to wireless communications, including, but not limited to, systems and methods for wireless communication device detection. [Background technology]

[0002] Coverage is a fundamental aspect of cellular network deployment. Mobile operators rely on different types of network nodes to provide comprehensive coverage in their deployments. As a result, new types of network nodes have been considered to increase mobile operators' flexibility for their network deployments. For example, some systems or architectures introduce integrated access backhaul (IAB), which can be augmented in other systems with a new type of network node that does not require a wired backhaul. Another type of network node is the RF repeater, which simply amplifies and forwards any signals they receive. RF repeaters have been widely deployed in 2G, 3G, and 4G to supplement the coverage provided by typical full-stack cells. Summary of the Invention [Means for solving the problem]

Mobile Communications Technology and Environment) FIG. 1 illustrates an example wireless communication network and / or system 100 in which the techniques disclosed herein according to embodiments of the present disclosure may be implemented. In the following discussion, the wireless communication network 100 may be any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and is referred to herein as “network 100.” Such example network 100 includes a base station 102 (hereinafter “BS 102,” also referred to as a wireless communication node) and a user equipment device 104 (hereinafter “UE 104,” also referred to as a wireless communication device), which can communicate with each other via a communication link 110 (e.g., a wireless communication channel), and a cluster of cells 126, 130, 132, 134, 136, 138, and 140 that overlap a geographic region 101. In FIG. 1, BS 102 and UE 104 are contained within the respective geographic boundaries of cell 126. Each of the other cells 130, 132, 134, 136, 138, 140 may include at least one base station operating in its assigned bandwidth to provide adequate wireless communication coverage to its intended users.

[0032] For example, the BS 102 may operate at an assigned channel transmission bandwidth to provide adequate communication coverage to the UE 104. The BS 102 and the UE 104 may communicate via a downlink radio frame 118 and an uplink radio frame 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In this disclosure, the BS 102 and the UE 104 are generally described herein as non-limiting examples of “communication nodes” capable of implementing the methods disclosed herein. Such communication nodes may be capable of wireless and / or wired communication in accordance with various embodiments of the present solution.

[0033] 2 illustrates a block diagram of an exemplary wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) in accordance with some embodiments of the present solution. System 200 may include components and elements configured to support known or conventional operational features that need not be described in detail herein. In one exemplary embodiment, system 200 can be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment, such as wireless communication environment 100 of FIG. 1, as described above.

[0034] The system 200 generally includes a base station 202 (hereinafter "BS 202") and a user equipment device 204 (hereinafter "UE 204"). The BS 202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each of which is coupled and interconnected as needed via a data communication bus 220. The UE 204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each of which is coupled and interconnected as needed via a data communication bus 240. The BS 202 communicates with the UE 204 over a communication channel 250, which can be any wireless channel or other medium suitable for the transmission of data as described herein.

[0035] As will be appreciated by those skilled in the art, system 200 may further include any number of modules other than those shown in FIG. 2 . Those skilled in the art will appreciate that the various exemplary blocks, modules, circuits, and processing logic described in connection with the embodiments disclosed herein may be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this compatibility and adaptability of hardware, firmware, and software, various exemplary components, blocks, modules, circuits, and steps have been described generally in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software may depend on the particular application and design constraints imposed on the overall system. Those familiar with the concepts described herein may implement such functionality in a manner suitable for each particular application, but such implementation decisions should not be construed as limiting the scope of the present disclosure.

[0036] According to some embodiments, the UE transceiver 230 may be referred to herein as the “uplink” transceiver 230, which includes a radio frequency (RF) transmitter and an RF receiver, each with circuitry coupled to an antenna 232. Alternatively, a duplex switch (not shown) may couple the uplink transmitter or receiver to the uplink antenna in a time-duplex manner. Similarly, according to some embodiments, the BS transceiver 210 may be referred to herein as the “downlink” transceiver 210, which includes an RF transmitter and an RF receiver, each with circuitry coupled to an antenna 212. Alternatively, a downlink duplex switch may couple the downlink transmitter or receiver to the downlink antenna 212 in a time-duplex manner. The operation of the two transceiver modules 210, 230 may be coordinated in time such that the downlink transmitter is coupled to the downlink antenna 212 while the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250. Conversely, the operation of the two transceivers 210, 230 may be coordinated in time such that the uplink transmitter is coupled to the uplink antenna 232 at the same time that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250. In some embodiments, there is close time synchronization with a minimum guard time between dual direction changes.

[0037] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via a wireless data communication link 250 and cooperate with a suitably configured RF antenna apparatus 212 / 232 capable of supporting a particular wireless communication protocol and modulation scheme. In some exemplary embodiments, the UE transceiver 210 and the base station transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards. However, it will be understood that the present disclosure is not necessarily limited in application to a particular standard and associated protocol. Rather, the UE transceiver 230 and the base station transceiver 210 may be configured to support alternative or additional wireless data communication protocols, including future standards or variants thereof.

[0038] According to various embodiments, the BS 202 may be, for example, an evolved node B (eNB), a serving eNB, a target eNB, a femto station, or a pico station. In some embodiments, the UE 204 may be embodied in various types of user devices, such as a mobile phone, a smartphone, a personal digital assistant (PDA), a tablet, a laptop computer, a wearable computing device, etc. The processor modules 214, 236 may be implemented or realized using a general-purpose processor, an associative memory, a digital signal processor, an application-specific integrated circuit, a field-programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. Thus, a processor may be realized as a microprocessor, a controller, a microcontroller, a state machine, etc. A processor may also be implemented as a combination of computing devices, such as a combination of a digital signal processor and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a digital signal processor core, or any other such configuration.

[0039] Furthermore, the steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied in hardware, firmware, directly in a software module executed by processor modules 214, 236, or any practical combination thereof. Memory modules 216, 234 may be realized as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216, 234 may be coupled to processor modules 210, 230, respectively, such that processor modules 210, 230 can read information from and write information to memory modules 216, 234, respectively. Memory modules 216, 234 may be integrated into each processor module 210, 230. In some embodiments, memory modules 216, 234 may each include cache memory for storing temporary variables or other intermediate information during execution of instructions to be executed by processor modules 210, 230, respectively. Memory modules 216, 234 may also each include non-volatile memory for storing instructions to be executed by processor modules 210, 230, respectively.

[0040] The network communications module 218 generally represents the hardware, software, firmware, processing logic, and / or other components of the base station 202 that enable bidirectional communications between the base station transceiver 210 and other network components and communication nodes configured to communicate with the base station 202. For example, the network communications module 218 may be configured to support Internet or WiMAX traffic. In a typical deployment, without limitation, the network communications module 218 provides an 802.3 Ethernet interface to enable the base station transceiver 210 to communicate with conventional Ethernet-based computer networks. In this embodiment, the network communications module 218 may include a physical interface for connecting to a computer network (e.g., a mobile switching center (MSC)). As used herein with respect to a specified operation or function, the terms “configured for,” “configured to,” and conjugations thereof refer to a device, component, circuit, structure, machine, signal, etc. that is physically configured, programmed, formatted, and / or arranged to perform the specified operation or function.

[0041] The Open Systems Interconnection (OSI) model (referred to herein as the "Open Systems Interconnection Model") is a conceptual, logical layout that defines network communications used by open systems (e.g., wireless communication devices, wireless communication nodes) to interconnect and communicate with other systems. The model is divided into seven subcomponents or layers, each of which represents a conceptual collection of services provided to its upper and lower layers. The OSI model also defines logical networks and effectively describes computer packet transfers through the use of different layer protocols. The OSI model may also be referred to as the seven-layer OSI model or seven-layer model. In some embodiments, Layer 1 may be the physical layer. In some embodiments, Layer 2 may be the medium access control (MAC) layer. In some embodiments, Layer 3 may be the radio link control (RLC) layer. In some embodiments, Layer 4 may be the packet data convergence protocol (PDCP) layer. In some embodiments, Layer 5 may be the radio resource control (RRC) layer. In some embodiments, layer 6 may be a non-access stratum (NAS) layer or an Internet Protocol (IP) layer, and layer 7 is some other layer.

[0042] To enable those skilled in the art to make and use the present solution, various exemplary embodiments of the present solution are described below with reference to the accompanying figures. As will be apparent to those skilled in the art, after reading this disclosure, various changes or modifications can be made to the examples described herein without departing from the scope of the present solution. Thus, the present solution is not limited to the exemplary embodiments and applications described and illustrated herein. Additionally, any specific order or hierarchy of steps in the methods disclosed herein is merely an example approach. The specific order or hierarchy of steps in a disclosed method or process can be rearranged based on design preferences while remaining within the scope of the present solution. Thus, those skilled in the art will understand that the methods and techniques disclosed herein present various steps or operations as a sample order, and that the present solution is not limited to the specific order or hierarchy presented, unless otherwise specified.

[0043] 2. Systems and Methods for Network Node (e.g., SN) Interference Measurement When certain systems (e.g., 5G New Radio (NR), Next Generation (NG) systems, 3GPP® systems, and / or other systems) move / migrate to relatively higher / larger frequencies (e.g., approximately 4 GHz in FR1 deployments and above 24 GHz in FR2), efficiency reductions in propagation (e.g., communication or transmission) conditions may be observed / identified compared to relatively lower frequencies. In such cases, it may be difficult to address the propagation efficiency reductions resulting from the use of relatively higher frequencies. Thus, cell densification (e.g., increased density) may be desirable. In certain scenarios, deployment of conventional full-stack cells may not be available (e.g., backhaul is unavailable) and / or feasible, such as when it is preferred. In certain systems, radio frequency (RF) repeaters with full-duplex amplify-and-forward operation can be used to provide comprehensive communication coverage in cellular network deployments. However, the use of RF repeaters may amplify both signals and noise, which may increase interference in such systems.

[0044] To minimize or avoid noise amplification, a network-controlled repeater (NCR) can be introduced as an enhancement over conventional RF repeaters, with the enhancement involving the ability to receive and / or process side-control information from the network. The side-control information can enable the network-controlled repeater to perform / execute / operate its amplification and forwarding operations more efficiently. Certain advantages can include at least mitigation of unwanted noise amplification, transmission and reception with better spatial directionality, and / or simplified network integration. Similar mechanisms or techniques for controlling signal (and / or noise) amplification can be performed, for example, by similar types of network devices as discussed herein.

[0045] The NCR can be considered a stepping stone to a reconfigurable intelligent surface (RIS). The RIS node can adjust the phase and amplitude of a received signal to improve / enhance communication coverage (e.g., network communication coverage). As discussed herein, network nodes, including but not limited to an NCR, a smart repeater, an enhanced RF repeater, a RIS, and / or an integrated radio access backhaul (IAB), can be represented, referred to, or provided as a smart node (SN) (e.g., a network node) for simplicity. For example, an SN can include, correspond to, or refer to a type of network node for assisting the BS 102 to improve communication coverage (e.g., avoid / prevent jamming / obstacles, extend transmission range, etc.). One or more SNs can be deployed to improve communication coverage, and some SN FUs can be activated (e.g., turned on) or deactivated (e.g., turned off) depending on whether there is a forwarding action for the SN FU (e.g., depending on whether there is at least one UE under the SN's communication coverage area, etc.).

[0046] In certain scenarios, one or more SNs may be deployed to improve the data rate of the UE 104. For example, the UE 104 may establish a connection with the BS 102 via an SN, and the SN may be an intermediary between the UE 104 and the BS 102. In such cases, the SN may be used to improve the data rate (e.g., transmission of data) of the UE 104. It may be difficult to determine which of the SNs is suitable for serving at least one UE 104 so that other SNs may be turned off to reduce potential interference and energy consumption. Therefore, when multiple SNs are deployed in a certain area, the systems and methods of the technical solutions discussed herein may provide (or introduce) mechanisms and / or techniques for determining whether one or more SNs should serve one or more UEs 104, whereby on / off commands (e.g., requests) may be sent to one or more SNs according to the determination.

[0047] 3 illustrates a schematic diagram of an example network 300. As illustrated in FIG. 3, one or more BSs 102A-102B (e.g., BS 102) may each serve one or more UEs 104A-104B (e.g., UEs 104) in their cells via one or more SNs 306A-306B (e.g., labeled SN 306), respectively, such as when obstructions exist between the BS(s) 102 and the UE(s) 104. The system and method may provide the SN 306, which is configured to measure signals communicated / received / acquired from the UE 104 and detect whether the UE 104 is under the communication coverage area of ​​the SN 306. In some cases, certain features or functionality of the SN 306 may be similar to that of the UE 104. The system and method of the present technical solution can provide various measurement configurations for the UE 104 to measure signals of other UEs 104 (e.g., Sounding Reference Signals (SRS), among other types of signals). For example, the UE 104 can measure crosslink interference (CLI). The system and method (or a network, such as the BS 102 or the SN 306) can configure the UE 104 to report / provide / indicate CLI measurement information to at least one of the SN 306 and / or the BS 102 based at least on SRS resources. The CLI measurement information based on SRS resources can include at least one of the following: Measurement results per SRS resource, and / or · SRS resource(s) index.

[0048] In some cases, the network may configure the UE 104 to report CLI measurement information based on CLI received signal strength indicator (RSSI) resources, including at least one of the following: CLI-RSSI measurement results per resource, and / or · CLI-RSSI resource(s) index(es).

[0049] In various implementations, the CLI measurement procedure may include multiple steps, such as step 1 and step 2 discussed herein. In step 1, the BS 102 may configure the UE 104 with a CLI measurement configuration. The measurement configuration may include at least one of the following parameters: 1) A measurement object configured in the measObjectCLI-r16 information element (IE). The measurement object may indicate the frequency and / or time location of the SRS resource and / or CLI-RSSI resource and / or the subcarrier spacing of the SRS resource to be measured by the UE 104. 2) Reporting configurations configured in the ReportConfigNR IE. A reporting configuration (e.g., sometimes called a measurement reporting configuration) can include, correspond to, or be part of a list, where a list can include one or more reporting configurations per measurement object. Each measurement reporting configuration can include / comprise at least one of the following: Reporting Criteria: Criteria that may trigger the UE 104 to send measurement reports. The reporting criteria may trigger the UE 104 to send measurement reports periodically (e.g., at predetermined time intervals) or as a single event (e.g., in response to receiving the criteria or at a predetermined time instance after receiving the criteria). Reference Signal (RS) Type: Including or corresponding to at least one of SRS and / or CLI-RSSI resources, etc. Reporting Format: Can be used to configure reported measurements as Reference Signal Received Power (RSRP) values ​​and / or Received Signal Strength Indicator (RSSI) values, among other types of values. 3) Measurement Identification (ID): For measurement reporting. A list of measurement identities may be included, where each measurement identity may link a measurement object with a respective reporting configuration. 4) Quantity Configuration: A quantity configuration may indicate / define / represent a measurement filtering configuration used for event evaluation / decision and / or related reporting and / or for periodic reporting of measurements.

[0050] In step 2, after receiving the configuration, the UE 104 may perform or execute a measurement operation. If there is at least one (e.g., applicable) CLI measurement resource to report, the UE 104 may initiate a reporting procedure / operation. For example: 1) For each SRS resource included in the measResultCLI, an associated SRS resource ID can be included in the report. The SRS resource ID can be used, for example, to identify or represent the SRS resource. The SRS RSRP result can be included in the Layer 3 filtered measurement result. In some cases, the SRS resource ID associated with each SRS RSRP result can be included in the Layer 3 filtered measurement result in decreasing / decreasing order, e.g., the highest / most interfering SRS resource (e.g., the SRS resource associated with the highest interference measurement value) can be listed as the first SRS resource ID. In some other cases, the SRS resource ID associated with each SRS RSRP result can be included in the Layer 3 filtered measurement result in increasing / increasing order, e.g., the lowest / least interfering SRS resource can be listed as the first SRS resource ID. 2) For each CLI-RSSI resource included in measResultCLI, an associated RSSI resource ID can be included in the report. The RSSI resource ID can be used, for example, to identify or represent the CLI-RSSI resource. The CLI RSSI results can be included in the Layer 3 filtered measurement results in, for example, decreasing order (e.g., the most interfering CLI-RSSI resource can be included first) or increasing order (e.g., the least interfering CLI-RSSI resource can be included first), etc., based on the configuration of the UE 104.

[0051] Referring to FIG. 4, a schematic diagram 400 of transmission links between the BS 102 and the SN 306 and between the SN 306 and the UE 104 is depicted. The SN 306 may include or consist of at least two units or functions / components (e.g., sometimes referred to as functional entities), such as a communication unit (CU) (e.g., an SN CU) and a forwarding unit (FU) (e.g., an SN FU). Each unit of the SN 306 may support different functions for communication with at least one of the BS 102 and / or the UE 104. A first unit (or functional entity) of the SN 306 may refer to an SN CU, and a second unit (or functional entity) of the SN 306 may refer to an SN FU, or vice versa. For example, the SN CU (e.g., the first unit) may be a network controlled repeater (NCR) MT. In another example, the SN FU (e.g., the second unit) may be an NCR forwarder / forwarder (Fwd). The SN CU may operate / behave similarly to the UE 104 or include similar functionality to the UE 104, for example, to receive and decode side control information from the BS 102. The SN CU may be a control unit, a controller, a mobile terminal (MT), part of a UE, a third-party IoT device, etc. The SN FU may perform intelligent amplify and forward operations using the side control information received by the SN CU. The SN FU may be a radio unit (RU), a RIS, etc.

[0052] The transmission links between the BS 102 and the SN 306 and between the SN 306 and the UE 104 as shown in FIG. 4 may be defined / described / provided as follows: C1: Control link from SN CU to BS (C-link); C2: Control link from BS to SN CU (C link); F1: Backhaul link from SN FU to BS; F2: Backhaul link from BS to SN FU; F3: Access link from UE to SN FU, and F4: Access link from SN FU to UE.

[0053] A control link (e.g., sometimes referred to as a communication link) may refer to or mean that a signal from one side is detected and decoded by the other side, whereby information transmitted within / via the control link can be utilized to control the status of a forwarding link (e.g., a backhaul link and / or an access link, F link). A forwarding link may mean that a signal from the BS 102 or the UE 104 is unknown to the SN FU. In this case, the SN FU may amplify and forward the signal without decoding it. For example, the F1 and F3 links may correspond to or be associated with complete uplink (UL) forwarding links (e.g., backhaul and access links, respectively) from the UE 104 to the BS 102, with F1 being the SN FU UL forwarding link. Furthermore, the F2 and F4 links may correspond to or be associated with complete DL forwarding links (e.g., backhaul and access links, respectively) from the BS 102 to the UE 104, with F4 being the SN FU DL forwarding link. The F1 link and the F2 link may correspond to or be referred to as a backhaul link, and the F3 link and the F4 link may correspond to or be referred to as an access link.

[0054] 5, an exemplary implementation structure 500 for UE detection is depicted. The structure 500 may include or illustrate various exemplary implementations of the technical solutions discussed herein, including, for example, but not limited to, a first exemplary implementation, a second exemplary implementation, and a third exemplary implementation.

[0055] (Example Implementation 1: BS configures SN to measure signals from UE) In various implementations, the BS 102 can configure / instruct the SN 306 to measure signals from individual UEs 104 to determine whether the UEs 104 are within the coverage area of ​​the SN 306. Various aspects or configurations can be considered or utilized for measuring signals from the UEs 104.

[0056] (Example Aspect 1 of Example Implementation 1: Type of Signal to be Measured by SN) In some aspects, to enable the SN 306 to perform measurement operations to detect whether one or more UEs 104 are within the communication coverage area of ​​the SN 306 (e.g., to serve the UE(s) 104), the SN 306 may be configured to measure / analyze signals transmitted from / by the UEs 104. At least one of the following example configurations (e.g., example configurations 1-3) or cases may be considered, implemented, or utilized.

[0057] (Illustrative Aspect 1 Case 1) In various cases, the SN 306 can be transparent to the UE 104. In those cases where the SN 306 is transparent to the UE 104, the UE 104 may, for example, exhibit or follow legacy behavior so that the UE 104 can operate normally (e.g., there are no additional procedures / steps to be performed by the UE 104). Taking into account different states or situations of the UE 104 (e.g., the UE 104 being in different states or situations), the following configurations or operations can be considered or performed:

[0058] (Configuration example 1 of case 1) In some configurations, the signal to be measured by the SN 306 can include or be a reference signal (RS) transmitted by the UE 104. For example, when the UE 104 operates in an RRC_connected state and the BS 102 is configured to introduce / indicate / designate an SN 306 to serve the UE 104 to improve / enhance the data rate (e.g., improve transmission / communication), the BS 102 can configure the SN 306 to measure the RS transmitted from the UE 104. The RS from the UE 104 can include at least one of an SRS, a demodulation reference signal (DM-RS), a phase tracking reference signal (PT-RS), etc.

[0059] (Configuration example 2 of case 1) In some configurations, the signal to be measured by the SN 306 may include a preamble transmitted / provided by / from the UE 104. For example, when the UE 104 operates in an RRC_idle state, the UE 104 may transmit / transmit / signal a preamble to initiate an initial access procedure. Because the SN CU may perform similar features or functions as the UE 104, the SN CU may receive cell-specific physical random access channel (PRACH) configurations used by one or more UEs 104. In such a case, when the SN 306 measures preambles from (or provided by) one or more UEs 104, the BS 102 may not be required to transmit / provide additional PRACH-related resource configurations to the SN 306, thereby reducing network traffic and / or resource consumption.

[0060] (Configuration example 3 of case 1) In some configurations, the signals to be measured by the SN 306 may include a physical uplink control channel (PUCCH) and / or a physical uplink shared channel (PUSCH) signal from the UE 104. For example, when the UE 104 operates in an RRC_connected state, the UE 104 may send / transmit at least one PUCCH and / or PUSCH signal to the BS 102. Based on the PUCCH and / or PUSCH signal, the BS 102 may configure corresponding frequency-related information and / or time-related information for the SN 306 for measurement (e.g., to perform measurements on the signal).

[0061] (Illustrative Aspect 1 Case 2) In various cases, the SN 306 may be non-transparent to the UE 104. In such cases, the UE 104 may transmit at least one dedicated signal to the SN 306. For example, the signal may be dedicated to the SN 306, so that when the SN 306 receives the signal, the SN 306 can determine its on / off state. In this example, the SN 306 may not report (or avoid reporting) measurements to the BS 102, so that the BS 102 does not need to determine the on / off state of the SN 306. In some other cases, when or after the UE 104 transmits the dedicated signal to the SN 306, the SN 306 may transmit measurements to the BS 102, such that the BS 102 determines the on / off state of the SN 306. In this case, the BS 102 may determine and provide an indication of the on / off state of the SN 306. At least one of the following configurations may be considered or implemented:

[0062] (Configuration example 1 of case 2) In some configurations, the signal to be measured by the SN 306 may include a dedicated preamble used for UE detection. The dedicated preamble may be transmitted from the UE 104 to the SN 306 on dedicated resources. The dedicated resources may include, among other things, at least one of a time domain resource of the PRACH opportunity, a frequency domain resource of the PRACH opportunity, and / or a (e.g., dedicated) preamble index. The dedicated resources may be configured for the SN 306 and / or the UE 104.

[0063] (Configuration example 2 of case 2) In some configurations, the signals to be measured by the SN 306 may include a reference signal (RS) having a dedicated / specific configuration for UE detection. For example, a reference signal transmitted with a dedicated or specific port index may be used for UE detection. In another example, a reference signal transmitted with a dedicated or specific RS index may be configured for UE detection (e.g., the SN 306 is configured to perform UE detection or signal measurements).

[0064] (Configuration example 3 of case 2) In some configurations, the signals to be measured by the SN 306 may include dedicated signals or sequences for UE detection. The dedicated sequences may include or correspond to at least one of an on-off keying (OOK) sequence, a computer-generated sequence (CGS), and / or a low peak-to-average power ratio (PAPR) sequence, a Zadoff-Chu (ZC) sequence, and / or a pseudo-random sequence, etc.

[0065] (Configuration example 4 of case 2) In some configurations, the signals to be measured by the SN 306 may include dedicated PUCCH transmissions for UE detection and / or dedicated PUSCH transmissions for UE detection.

[0066] (Example Aspect 2 of Example Implementation 1) In some aspects, the SN 306 can determine the type / kind of measurement to take / perform / initiate. At least one of the following configurations (e.g., Example Configuration 1 and / or Example Configuration 2) can be considered / utilized for the measurement type of the SN or performed by the SN 306:

[0067] (Configuration Example 1 of Illustrative Aspect 2) In some configurations, the SN 306 may not need or be required to decode signals transmitted from the UE 104. The SN 306 may perform RSSI measurements of signals transmitted by / from the UE 104.

[0068] (Configuration Example 2 of Illustrative Aspect 2) In some configurations, the SN 306 may decode the corresponding signal transmitted by the UE 104. Subsequently, the SN 306 may perform at least one of a Reference Signal Received Power (RSRP), a Reference Signal Received Quality (RSRQ), a Signal-to-Interference-and-Noise Ratio (SINR) measurement, and / or a Signal-to-Interference Ratio (SIR), among other measurements, for the signal transmitted from / by the UE 104.

[0069] (Example Aspect 3 of Example Implementation 1) In various aspects, the SN 306 can be configured with at least one measurement configuration (e.g., a measurement configuration known to the SN 306). If the SN 306 is to perform signal measurements on one or more signals from the UE 104, the SN 306 can be configured with resource information used in / by the transmitted signals (e.g., the SN 306 can know the resource information). In some cases, if the SN 306 is to report measurement results to the BS 102, the SN 306 can be configured with report content (e.g., type of report content) and / or report format-related information (e.g., the SN 306 can know the same), such as to generate and provide a report to the BS 102. In these aspects, the measurement configuration to be sent to or configured for the SN 306 can include, but is not limited to, at least one of the following example information (e.g., example information 1-3):

[0070] (Example Information 1 of Illustrative Aspect 3) In various implementations, one or more signal configurations may be provided or configured for the SN 306. The signal configurations may be used to specify / indicate resource information for the SN 306 to measure signals transmitted by / from the UE 104. For each signal configuration, at least one of the following information may be configured for / to the SN 306: 1) At least one signal index. The signal index may be used to specify a signal to be measured by the SN 306 and / or transmitted from the UE 104. The format of the signal index may include one of an RS index, a logical index, and / or a preamble index, etc. 2) Sequences and / or information used to generate and / or initialize RS sequences. The sequences may include dedicated sequences of the SN 306 (e.g., as described above, the UE 104 may be opaque to the SN 306, and thus the dedicated sequences may be transmitted to the SN 306), and RS sequences (e.g., if the UE 104 is transparent to the SN 306, the UE 104 may transmit an SRS to the BS 102, and the BS 102 may configure the SN 306 to measure the SRS transmitted from the UE 104, and thus RS sequence-related information may be notified to the SN 306). 3) Information used to indicate resource information of the signal, which may include at least one of the following: Frequency resource information. The frequency resource information may include at least one of a start frequency location, an end frequency location, a number of physical resource blocks (PRBs) and / or REs, a frequency offset and / or a frequency shift, an absolute radio frequency channel number (ARFCN), a global synchronization raster (GSCN), etc. i. For example, the format of the starting frequency location may include or correspond to at least one of a starting PRB, a starting resource element (RE), a PRB, and / or an RE offset compared to a reference point (e.g., point A, the start of the bandwidth portion (BWP)), etc. ii. In another example, the format of the end frequency location may include or correspond to at least one of an end / last PRB, an end RE, an RB, and / or an RE offset compared to a reference point (e.g., point A, start of BWP), etc. iii. In yet another example, the format of the frequency offset may be at least one of a number of PRBs and / or a number of RE offsets compared to a reference point. b. Time resource information. The time resource information may include at least one of a periodicity, a slot offset, a starting slot and / or symbol, a number of slots and / or symbols, a start and length indicator value (SLIV), a pattern, a time domain resource allocation (TDRA) index, a duty cycle, etc. i. For example, the format of the starting slot can be a slot index and / or a slot offset compared to a reference slot. ii. In another example, the format of the starting symbol can be a symbol index and / or a symbol offset compared to a reference point (eg, the first symbol in the slot, or the last symbol in the slot). c. Subcarrier spacing (SCS). d. Cell ID (e.g., index). In some implementations, the cell ID / index can be used to determine the cell to which the configured BWP belongs. In some implementations, this parameter (e.g., cell ID) may or may not be configured depending on the configuration. If this parameter is not configured, for example, the primary cell can be used as the default cell. e. Bandwidth Part (BWP) ID / Index. In some implementations, the BWP can be used to derive, determine, or identify a reference point for an RS resource. f. One or more beam information used by the SN 306 for UE detection. The beam information may include one or more beam indices of the access link and / or one or more beam information of the backhaul link (e.g., beam index, TCI status, etc.). In some implementations, one or more beam information may be used for each measurement signal. In some implementations, the beam information used for different measurement signals may be the same or different (e.g., between different measurement signals). g. One or more panel information used by the SN 306 for UE detection. The panel information may include one or more panel information (e.g., panel IDs) for access links and / or one or more panel information (e.g., panel IDs) for backhaul links. In some implementations, one or more panel information may be used for each measurement signal. In some implementations, the panel information used for different measurement signals may be the same or different. h. One or more port information used to measure the signal. The port information may include or correspond to one or more port information of an access link and / or one or more port information of a backhaul link. In some implementations, one or more port information may be used for each measurement signal. In some implementations, the port information used for different measurement signals may be the same or different. i. Random Access Channel (RACH) opportunities.

[0071] (Example Information 2 of Illustrative Aspect 3) In various implementations, one or more reporting configurations can be provided or configured for the SN 306. If the SN 306 is to report measurement results (e.g., results of measuring a signal) to the BS 102, the SN 306 can be configured (e.g., know or have information about) the report type / kind and / or format of the measurement results to provide or include as part of the report to the BS 102. In such implementations, for each reporting configuration, at least one of the following information can be configured to / for the SN 306: 1) One or more Measurement Report IDs. Each Measurement Report ID can be used to identify a reporting configuration. 2) Report Type: Report types can include or be periodic and / or event-triggered (e.g., reports can be triggered in response to certain events). a. For example, if the reporting type is periodic, relevant parameters for enabling periodic reporting can be configured for the SN 306. The relevant parameters can include at least one of the following: a maximum number of measurement signals to be reported in a report; the number of reports; a measurement quantity to be included in the report (e.g., RSRP, RSRQ, SINR, RSSI, and / or SIR, etc.); a reporting interval specifying the interval between periodic reports; and a threshold value associated with a selected trigger quantity. In this case, the threshold value can include one or more specific values ​​to be used for comparison with the measurement result. The specific value can be used to determine whether the SN 306 should trigger a periodic report; for example, if the measurement result is greater than the threshold value, the SN 306 can report the result. b. In another example, if the report type is event-triggered, the (e.g., current) event herein can be reused for the measurement; and / or a new event can be defined for the measurement. Related parameters for enabling event-triggered reporting can be configured for the SN 306. The related parameters can include at least one of: an event ID; a maximum number of measurement signals to be included in the report; the number of reports; a measurement quantity to be included in the report (e.g., RSRP, RSRQ, SINR, RSSI, and / or SIR, etc.); a reporting interval specifying the interval between reports; a threshold associated with a selected trigger quantity, a time (e.g., time range, duration, or instance) when a particular criterion for the event should be met / satisfied to trigger a report (e.g., for the SN 306 to initiate a report or generate a report); an indication of whether the SN 306 should initialize a reporting procedure when a leave condition is met for the measurement signal; a hysteresis parameter used within the entry condition and / or leave condition of the event-triggered reporting condition, etc. 3) An indication as to whether beam level measurements should be reported in the report. The beam level measurement values ​​may include or correspond to the signal strength measured by the SN 306 using a particular (or indicated) beam. 4) The maximum number of beam level measurement result values ​​that can be reported for a measurement signal. 5) One or more measurement filtering coefficients used to process the measurement results.

[0072] (Example Information 3 of Illustrative Aspect 3) In various implementations, one or more measurement filtering coefficients used to process the measurement results can be configured or provided to the SN 306. In some implementations, the measurement filtering coefficients can be the same or different for different measurement signals. In some implementations, the measurement filtering coefficients can be the same or different for different measurands.

[0073] (Example Information 4 of Illustrative Aspect 3) In various implementations, if the measurement signal is an RS from the UE 104 and the measurement quantity is at least one of RSRP, RSRQ, SINR, and / or SIR, among others, the SN 306 may decode the RS from the UE 104. In such a case, RS-related configuration may be configured to / for the SN 306. The RS-related configuration may include at least one of the following: 1) Information used to generate and / or initialize RS sequences. For example, if the signal used for measurement is an SRS, the sequence ID used to initialize the pseudo-random group and / or sequence hopping may be configured for the SN 306. In another example, if the signal used for measurement is a DM-RS, scrambling ID0 (e.g., a first ID) and / or scrambling ID1 (e.g., a second ID) used for DM-RS scrambling initialization may be used to indicate to the SN 306. 2) RS configuration related parameters can be configured for the SN 306. For example, if the SN 306 should measure an SRS transmitted from the UE 104. Current SRS resource-related configuration parameters (e.g., number of ports and / or antenna port index) may be configured for the SN 306. In some implementations, when this configuration is used for measurement operations of the SN 306, some of the parameters and / or fields may be predefined as specific values. For example, frequency hopping, sequence group hopping, and / or sequence hopping fields may be configured as disabled / inactive. b. In another example, if the measurement signal is a dedicated preamble and / or a dedicated sequence from the UE 104, the measurement quantity may include or correspond to at least one of RSRP, RSRQ, SINR, etc.

[0074] (Example Information 5 of Illustrative Aspect 3) In various implementations, the information may include a signal-to-interference ratio (SIR). At least one of the following information may be configured or provided to the SN 306: 1) Information used to generate a sequence of a measurement signal. For example, if the signal used for measurement is an SRS, a sequence ID used to initialize a pseudo-random group and / or sequence hopping can be configured for the SN 306. In another example, if the signal used for measurement is a DM-RS, scrambling ID0 and / or scrambling ID1 used for DM-RS scrambling initialization can be used to indicate to the SN 306. 2) Preamble Index: For example, if there is a dedicated preamble used for measurements of SN 306, the dedicated preamble index may be configured for N 306.

[0075] (Example Information 6 of Illustrative Aspect 3) In various implementations, if the measurement signal is based on a preamble transmitted from the UE 104: 1) If the SN 306 is transparent to the UE 104, the measured preamble can be a legacy configuration used for random access procedures. Because the SN CU may perform or exhibit similar features or functions as certain UEs 104, the SN CU may receive cell-specific PRACH-related configuration from the BS 102. In some implementations, the SN 306 may monitor during various PRACH occasions to detect preambles transmitted by the UE 104. Additionally or alternatively, the BS 102 may indicate to the SN 306 whether the SN 306 should monitor and / or measure preambles transmitted from the UE 104 during PRACH occasions. For example, a new bit can be configured by the BS 102 for the SN 306 to enable or disable the SN 306's monitoring operation during PRACH occasions. 2) If the SN 306 is non-transparent to the UE 104, a dedicated preamble with a dedicated PRACH opportunity resource configuration may be considered or provided for measurement. The dedicated resource may include at least one of a time resource, a frequency resource, and / or a preamble index. The dedicated resource may be configured for the SN 306 and / or the UE 104. 3) For each signal configuration, there may be one or more associated reporting configurations. For different measurement resource configurations, the associated reporting configurations may be the same or different. Each reporting configuration may be associated with one or more signal configurations.

[0076] (Example Aspect 4 of Example Implementation 1) In various aspects, the above configuration parameters configured to / for the SN 306 can be conveyed / communicated / signaled via at least one of an Operation, Administration, and Maintenance (OAM) signal, a System Information (SI) signal, a Radio Resource Control (RRC) signal, a Downlink Control Information (DCI) signal, and / or a Medium Access Control Control Element (MAC CE) signal, among other types of signals / signaling. Different configuration parameters can be configured in the same and / or different signaling. For example, the configuration parameters can be conveyed as follows: 1) Via OAM signaling: One or more configurations shown in SN 306 can be configured by the network (eg, BS 102) via OAM. 2) Via SI signal. One or more configurations can be configured by the BS 102 via SI. The configuration for measurement operation of the SN 306 can be the same for various SNs 306 in the cell. 3) Via RRC signaling: One or more configurations can be configured via RRC messages. 4) Via DCI signaling, one or more new DCI fields may be defined / configured; and / or at least one existing DCI field may be reinterpreted / reconfigured / redefined. 5) Via MAC CE signaling, at least one new MAC CE can be defined. 6) Via RRC and DCI signals: At least one of the one or more configurations can be configured in an RRC message / signal; and / or at least one of the configurations can be activated / enabled by a DCI signal. 7) Via RRC signaling and MAC CE signaling: At least one of the one or more configurations can be configured in an RRC message / signaling; and / or at least one of the configurations can be activated / enabled by MAC CE signaling. 8) Via RRC signaling, MAC CE signaling, and DCI signaling: At least one of the one or more configurations can be configured in an RRC message, and a part / portion of the one or more configurations can be selected by or according to the MAC CE signaling; and / or at least one of the configurations can be activated by the DCI signaling. 9) Via OAM and DCI signals. One or more configurations are configured by the BS 102 via OAM signals. In some cases, one or more parameters of the one or more configurations can be updated by or in accordance with the DCI signals. 10) Via OAM and MAC CE signaling. One or more configurations may be configured by the BS 102 via OAM signaling. In some cases, one or more configurations may be updated via MAC CE signaling.

[0077] (Example Implementation 2: Post-measurement operation of SN) In various implementations, in response to or after receiving a configuration (e.g., for signal measurements) from the BS 102, the SN 306 may begin measuring signaling from the UE 104 according to the configuration from the BS 102. After the measurements (e.g., after the measurements), the SN 306 may perform at least one of the following example configurations or actions:

[0078] (Configuration Example 1 of Exemplary Implementation 2) In some configurations, the SN 306 may directly determine its on / off state / status (e.g., its own). In various implementations, the determination of its on / off status may be based on or according to at least one of the following: 1) The measurement result may be compared with one or more thresholds. According to the result of the comparison, the SN 306 may determine its on / off state. For example, if the SN 306 is non-transparent to the UE 104 and the UE 104 transmits a dedicated signal of / used by the SN 306 for measurement (e.g., a dedicated preamble, a dedicated RS with a specific port index, a dedicated RS with a specific RS index, a dedicated signal or data sequence, and / or a dedicated PUCCH or PUSCH transmission, etc.), the SN 306 may measure the signal. In some implementations, one or more thresholds may be configured for the SN 306. The SN 306 may measure the signal and compare the resulting value (e.g., the measurement result) with threshold(s) to determine its on / off state. For example, if the measurement result value is greater / higher than the threshold, the SN 306 may turn on or maintain activity of transmission and / or reception operations on at least one of the forwarding links. The one or more thresholds may be predefined for the SN 306; and / or the one or more thresholds may be configured for the SN 306 by the BS 102 via at least one of RRC, MAC CE, and / or DCI signaling, among other types of signaling. In some cases, the one or more thresholds may be determined based on the capabilities of the SN 306. 2) The on / off state can be determined by the number of detected signals. For example, the UE 104 may transmit multiple dedicated sequences to the SN 306, and the SN 306 may count, identify, or determine the number of detected sequences. If the number of detected sequences is higher / greater than a certain value, the SN 306 may decide to turn on. The certain value can be predefined for the SN 306; and / or the certain value can be configured for the SN 306 by the BS 102 via at least one of RRC, MAC CE, and / or DCI signaling, among other types of signaling. In some cases, the certain value can be determined based on the capabilities of the SN 306. In some implementations, the certain value can be the same or different for different signals. 3) The on / off state can be determined according to whether a corresponding signal is detected. For example, the UE 104 may transmit a dedicated PUSCH transmission to the SN 306. If the SN 306 detects this dedicated signal (e.g., a PUSCH transmission from the UE 104), the SN 306 can decide to turn on / activate. In some implementations, the dedicated signal transmitted from the UE 104 to the SN 306 can represent or correspond to a wake-up signal. In such a case, the SN 306 can turn on when it receives this type / kind of dedicated / specific signal. This specific / dedicated signal can be predefined for the SN 306 and / or the UE 104; and / or this specific / dedicated signal can be configured for the SN 306 and / or the UE 104 by the BS 102 via at least one of RRC, MAC CE, and / or DCI signaling, among other types of signaling.

[0079] In some implementations, the SN 306 may report the on / off status to the BS 102, such as after determining the on / off status / state of the SN 306. For example, in a relatively high data rate scenario, when the SN CU controls multiple SN FUs, if a particular measurement result of the SN FU does not satisfy / meet a (e.g., predefined or predetermined) threshold, the SN CU may determine that the corresponding SN FU may not be suitable for serving one or more UEs 104. In this case, the SN CU may directly turn off or deactivate (e.g., power off) the corresponding SN FU. The SN CU may report to the BS 102, and the report may include information about / regarding the set of SN FUs to be turned off / deactivated, for example, after determining that the corresponding SN FU may not be suitable for serving the UE 104.

[0080] In another example, if the measurement result of the SN 306 does not satisfy the threshold, the SN CU may directly turn off the corresponding SN FU. In this example, if the BS 102 does not receive measurement result-related information (e.g., measured RSRP and / or RSSI values, and / or the on / off status of the SN 306) from the SN 306, the BS 102 may determine that the corresponding SN FU is in an off status (e.g., the SN 306 is deactivated).

[0081] (Configuration Example 2 of Exemplary Implementation 2) In some configurations, the SN 306 may report the measurements to the BS 102. The reported measurements may include at least one of the following: 1) One or more / multiple signal indexes. 2) For each measurement signal, the content of the reported measurement result value may include or be at least one of the following: Signal Strength. The signal strength format may include at least one of RSRP, RSRQ, SINR, SIR, and / or RSSI, among others. For example, if no beam information is configured for the measurement signal (e.g., no beam information configuration), or if only one beam configuration is configured for the measurement signal, the reported result for the measurement signal may include a single signal strength. b. Signal strength, which is an average strength calculated among (or determined based on) various beam-level signal strengths. The beam-level signal strength can be the signal strength measured by the SN 306 (e.g., a network node) using a particular beam. For example, if multiple beams are configured for the SN 306 to be used for measurement signals, the reported result of the corresponding measurement signal can include a signal strength value. The signal strength value can be a joint value or an average value determined using multiple beam-level signal strength values. In some implementations, one or more thresholds can be configured by the BS 102 for / on the SN 306 via at least one of RRC, MAC CE, and / or DCI signaling, etc. In some cases, the threshold(s) can be configured for the SN 306 via OAM. The threshold can be used to compare with one or more beam-level signal strength values. In some implementations, one or more beam-level signal strength values ​​higher / greater than the threshold can be used to determine / calculate the reported signal strength value. In some implementations, the one or more configured thresholds for each measurement signal can be the same or different. c. One or more beam-level signal strengths and / or one or more associated beam information. For example, if multiple beams are configured for a measurement signal, the reported result for the corresponding measurement signal may include one or more signal strengths and / or one or more associated beam information. The signal strengths and associated beam information may be a one-to-one mapping. In some implementations, the reported result may include multiple pairs, each pair including a signal strength value and associated beam information. The maximum number of beam-level signal strengths that can be included in the report for each measurement signal may be configured by the BS 102 for the SN 306. d. The strongest beam level signal strength among various beam level signal strengths and / or associated beam information (e.g., the highest relative signal strength value). eN strongest beam level signal strengths and / or corresponding N beam information. N can be the number of beam level signal strengths to be reported. N can be configurable for the SN 306 and / or the BS 102 via OAM. In some cases, N can be configurable for the SN 306 by the BS 102 via at least one of RRC, MAC CE, DCI signaling, etc. For example, the BS 102 can configure the SN 306 to report only the first N strongest beam level signal strength values. The SN 306 can report the first N strongest beam level signal strength values ​​among the various measured beam level signal strength values. In some implementations, if the total number of beam level signal strength values ​​measured by the SN 306 is less than N, the SN 306 can report various beam level signal strength values ​​and / or associated beam information. The SN 306 can report only the strongest beam level signal strength value and / or corresponding beam information. f. An integer value determined according to a comparison between the measured signal strength and one or more threshold values. i. For example, the RSRP value of the corresponding RS resource can be an integer value. In some cases, a predefined table can be used to map the value of the measured quantity to a past or previously reported integer value in the measurement report. In some implementations, a current (e.g., existing) table can be reused, for example, a current SRS-RSRP measurement report mapping table can be reused. In some other implementations, a new table can be predefined / predetermined or configured for the SN 306. ii. In another example, the reported result value may include or correspond to a measured signal status and / or a measured signal level (e.g., obtained by comparing the signal strength value of the signal against / to a threshold value). For example, the signal strength value used for comparison may be a raw measurement value and / or a value obtained after processing the raw value via Layer 1 filtering and / or Layer 3 filtering (among other types of filtering). In this example, one or more sets of thresholds may be configured / defined according to different measurement signaling. In each set of thresholds, one or more thresholds may be defined to determine different levels of the measured signal. For example, set 1 (e.g., first set) may be for SRS measurements, set 2 (e.g., second set) may be for preamble measurements, etc. In each set, different values ​​of the threshold may be used to determine different statuses / levels of the corresponding measured signal, as shown in exemplary Tables 1 and 2. [Table 1] [Table 2] iii. In some cases, the one or more thresholds may be pre-defined for the SN 306 or may be configured for the SN 306 by the BS 102 via at least one of RRC, MAC CE, and / or DCI signaling, etc. In some other cases, the one or more thresholds may be determined based on or according to capabilities or suitability / support of / by the SN 306. g. One or more integer values ​​determined according to a comparison between the beam-level signal strength and one or more thresholds and one or more associated beam information. For example, the one or more thresholds may be predefined for the SN 306; and / or the one or more thresholds may be configured for the SN 306 by the BS 102 via at least one of RRC, MAC CE, and / or DCI signaling, among others. In some cases, the one or more thresholds may be determined based on the capabilities of the SN 306.

[0082] In some implementations, the signal strength values ​​described above can include or be values ​​that have been processed, for example, by Layer 1 (L1) filtering and / or Layer 3 (L3) filtering, or other types of filtering. Given the reporting measurement content of different techniques / mechanisms, the type(s) of measurement content that the SN 306 is configured to report to the BS 102 can be determined or selected according to OAM of the SN 306 and / or the BS 102, predefined for the SN 306 and / or the BS 102, and / or determined by the BS 102 for the SN 306 via at least one of RRC, MAC CE, and / or DCI signaling, etc.

[0083] (Configuration Example 3 of Exemplary Implementation 2) In some configurations, the SN 306 may send / transmit / provide / signal an indication to the BS 102 indicating whether one or more UEs 104 are under or within the communication coverage area of ​​the SN 306. For example, this indication provided by the SN 306 may include or correspond to a 1-bit field. A bit value of 1 may indicate / represent that there are one or more UEs 104 within the SN communication coverage area. A bit value of 0 may indicate that there are no UEs 104 within the SN communication coverage area. Depending on the configuration, a bit value of 0 may indicate that there are one or more UEs 104 within the SN communication coverage area, and a bit value of 1 may indicate, for example, that there are no UEs 104 within the SN communication coverage area.

[0084] In some implementations, when an SN CU controls multiple SN FUs and these SN FUs are located at different locations, the SN 306 may report to the BS 102 whether one or more UEs 104 exist under the communication coverage area of ​​each SN FU. For example, a bit field may be used to indicate whether one or more UEs 104 exist under the communication coverage area of ​​the SN FU. A panel ID may be used to represent (or indicate) SN FU information. In this case, one or more pairs of {bit field, panel ID} (e.g., a pair of bit field and panel ID) may be used to indicate whether at least one UE 104 exists under / belongs to the communication coverage area of ​​the corresponding SN FU. In another example, a bitmap may be used to indicate whether one or more UEs 104 exist under the communication coverage area of ​​each SN FU. For example, for this bitmap, each bit may be used to represent an SN FU. Depending on the configuration, a bit value of 1 (or 0) can represent one or more UEs 104 within the communication coverage area of ​​the corresponding SN FU, and a bit value of 0 (or 1) can represent no UEs 104 within the communication coverage area of ​​the corresponding SN FU.

[0085] In various configurations, various information to be reported by the SN 306 to the BS 102 (e.g., as described above in exemplary implementation 2) can be carried / transmitted / provided / communicated via at least one of RRC, MAC CE, and / or uplink control information (UCI) signaling, among others. Additionally or alternatively, different parameters can be configured in the same and / or different signaling. For example, an indication can be conveyed in uplink control information (UCI) via transmission in a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH), and / or medium access control element (MAC CE) signaling via transmission in a PUSCH, among others.

[0086] (Example Implementation 3: BS Controls the On / Off Status of SN) In various implementations, the BS 102 can be configured to control the on / off status / state of the SN 306. After the SN 306 has finished / completed / performed the measurement operation, the SN 306 can perform one or more other post-measurement operations, such as one or more of the operations or configurations described in connection with exemplary implementation 2. After the SN 306 has performed the other one or more post-measurement operations, the indication of the on / off status can include at least one of the following configurations:

[0087] (Configuration Example 1 of Exemplary Implementation 3) In some configurations, the on / off status indication may be explicit, such as explicitly indicated / signaled by the BS 102 to the SN 306. The on / off status indication may include / have at least one of the following granularities: 1) On / off indication per SN level. For example, the BS 102 can indicate or provide on / off status to a particular SN 306. The on / off indication may be applicable for one particular SN 306. 2) Group-level on / off indication. For example, the BS 102 can indicate on / off status to one or more SNs 306 in a group. In this case, the on / off indication may be applicable for / to one or more SNs 306 in a particular group, or may be applicable for one or more SN FUs controlled by the same SN CU. 3) Beam-level on / off indication. For example, the BS 102 may indicate applicable on / off status for one or more beams of the SN 306. In this case, the beam information and corresponding on / off status may be indicated (e.g., simultaneously or together) to the SN 306. In some cases, the beam information may include or correspond to access link beam information and / or backhaul link beam information. 4) Link-level on / off indication. For example, the BS 102 may indicate applicable on / off status for one or more links of the SN 306. In this case, the link information and the corresponding on / off status may be indicated (e.g., indicated together) to the SN 306. In some cases, the link information may include at least one of forwarding link 1 (e.g., F1), forwarding link 2 (e.g., F2), forwarding link 3 (e.g., F3), and / or forwarding link 4 (e.g., F4). 5) Panel-level on / off indication. For example, the BS 102 may indicate applicable on / off status for one or more panels of the SN 306. In this case, panel information and corresponding on / off status may be indicated for the SN 306. In some cases, the panel information may include or correspond to access link panel information and / or backhaul link panel information. 6) Signal Type Level On / Off Indication. For example, the BS 102 may indicate applicable on / off status for one or more signal types. For example, the BS 102 may indicate an off status to the SN 306. This off status indication may be applicable (only) for UE-specific signal transfer, while the SN 306 may maintain / retain the on status for common signal transfer operations. 7) Port-level on / off indication. For example, the BS 102 may indicate applicable on / off status for one or more ports of the SN 306. In this case, port information and corresponding on / off status may be indicated to the SN 306. In some cases, the port information may include or correspond to access link port information and / or backhaul link port information. 8) Band-level on / off indication. For example, the BS 102 may indicate applicable on / off status for one or more bands of the SN 306. In this case, band information and corresponding on / off status may be indicated to the SN 306. In some cases, the band information may include or correspond to one or more band information for an access link and / or one or more band information for a backhaul link.

[0088] Additionally or alternatively, the granularity of the on / off status / state of SN306 discussed herein may be applicable or may be applied to various example configurations of example implementation 2 (e.g., example configuration 1), for example.

[0089] (Configuration Example 2 of Exemplary Implementation 3) In some configurations, the on / off status indication may be implicitly indicated by the BS 102 to the SN 306. In this configuration, at least one of the following may be considered or implemented: 1) If the BS 102 does not have (or is not configured to send) an explicit on / off status indication for / to the SN 306, the SN 306 may maintain / retain the off status until the SN 306 receives / obtains / acquires side control information from the BS 102. If the SN receives beam information from the BS 102, the on / off status of the SN 306 may be determined by, based on, or in accordance with (e.g., implicitly) the beam information. 2) If the BS 102 does not have an explicit on / off status indication for the SN 306, the SN 306 may maintain the on status until the SN 306 receives side control information from the BS 102. If the SN 306 receives beam information from the BS 102, the on / off status of the SN 306 can be determined (e.g., implicitly) according to the beam information.

[0090] In various configurations, the information to be indicated by the BS 102 to the SN 306 (e.g., as described above in example implementation 3) can be conveyed / communicated via at least one of RRC, MAC CE, and / or DCI signaling, among others. Additionally or alternatively, different parameters can be configured in the same signaling and / or different signaling.

[0091] Referring now to Figure 6, a flow diagram of an example method 600 for wireless communication device detection according to an embodiment of the present disclosure is depicted.

In some implementations, if the network node detects / identifies that an explicit ON / OFF indication is not received (e.g., is absent) from the wireless communication node, the network node may determine (or trigger) an ON state of the network node until the network node receives control information used to control the forwarding behavior of the network node from the wireless communication node.

In some implementations, if the network node receives beam information for controlling the forwarding operation of the network node from the wireless communication node, the on / off state of the network node may be implicitly indicated according to the received beam information.
