Description

Technical Field

[0001] The present disclosure relates generally to wireless communications, including but not limited to systems and methods for wireless communications device detection. Background Art

[0002] Coverage is a fundamental aspect of cellular network deployment. Mobile operators rely on different types of network nodes to provide blanket coverage in their deployments. As a result, new types of network nodes are thought to increase the flexibility of mobile operators in network deployment. For example, some systems or architectures introduce Integrated Access and Backhaul (IAB), which is a new type of network node that does not require a wired backhaul and can be enhanced in some other systems. Another type of network node is the Radio Frequency (RF) repeater, which simply amplifies and forwards any signal they receive. RF repeaters have been widely deployed in 2G, 3G, and 4G to supplement the coverage provided by conventional full-stack units. Summary of the invention

[0041] Figure 1 An example wireless communication network and / or system 100 is shown in accordance with an embodiment of the present disclosure, in which the techniques disclosed herein may be implemented. In the discussion that follows, 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 an example network 100 includes a base station 102 (hereinafter referred to as "BS 102"; also referred to as a wireless communication node) and a user equipment device 104 (hereinafter referred to as "UE 104"; also referred to as a wireless communication device) that may 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 covering a geographic area 101. In Figure 11, BS 102 and UE 104 are included within the respective geographic boundaries of cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating with its allocated bandwidth to provide adequate radio coverage to its intended users.

[0042] For example, BS 102 may operate on an allocated channel transmission bandwidth to provide adequate coverage to UE 104. BS 102 and UE 104 may communicate via downlink radio frames 118 and uplink radio frames 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In the present disclosure, BS 102 and UE 104 are described herein as non-limiting examples of "communication nodes", which may generally practice the methods disclosed herein. According to various implementations of the present solution, such communication nodes may be capable of wireless and / or wired communication.

[0043] Figure 2 A block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., Orthogonal Frequency Division Multiplexing (OFDM) / Orthogonal Frequency Division Multiple Access (OFDMA) signals) according to some embodiments of the present solution is shown. The system 200 may include components and elements configured to support known or conventional operating features that need not be described in detail herein. In an illustrative embodiment, as described above, the system 200 may be used in a communication system such as Figure 1 The wireless communication environment 100 may be used to communicate (eg, transmit and receive) data symbols.

[0044] System 200 generally includes a base station 202 (hereinafter referred to as "BS 202") and a user equipment device 204 (hereinafter referred to as "UE 204"). BS 202 includes a BS 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 to and interconnected with each other via a data communication bus 220 as needed. UE 204 includes a UE transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each of which is coupled to and interconnected with each other via a data communication bus 240 as needed. BS 202 communicates with UE 204 via a communication channel 250, which can be any wireless channel or other medium suitable for data transmission as described herein.

[0045] As will be appreciated by those skilled in the art, the system 200 may also include Figure 2 Any number of modules outside the modules shown. It will be appreciated by those skilled in the art that the various illustrative blocks, modules, circuits, and processing logic described in conjunction with the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any actual combination thereof. In order to clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are generally described according to their functions. Whether such functions are implemented as hardware, firmware, or software depends on the specific application and design constraints imposed on the entire system. People familiar with the concepts described herein can implement such functions in a manner suitable for each specific application, but such implementation decisions should not be interpreted as limiting the scope of the present disclosure.

[0046] According to some embodiments, the UE transceiver 230 may be referred to herein as an "uplink UL" transceiver 230, which includes a radio frequency RF transmitter and an RF receiver, each including circuitry coupled to an antenna 232. A duplex switch (not shown) alternatively couples 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 a "downlink DL" transceiver 210, which includes an RF transmitter and an RF receiver, each including circuitry coupled to an antenna 212. The downlink duplex switch alternatively couples the downlink transmitter or receiver to the downlink antenna 212 in a time duplex manner. The operation of the two transceiver modules 210 and 230 may be coordinated in time such that the uplink receiver circuit is coupled to the uplink antenna 232 to receive transmissions over the wireless transmission link 250 while the downlink transmitter is coupled to the downlink antenna 212. Instead, the operation of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver coupled to the downlink antenna 212 receives transmissions over the wireless transmission link 250 at the same time as the uplink transmitter coupled to the uplink antenna 232. In some embodiments, tight time synchronization with minimal guard times between changes in duplex direction is provided.

[0047] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via a wireless data communication link 250 and cooperate with an appropriately configured RF antenna arrangement 212 / 232 that can support a specific wireless communication protocol and modulation scheme. In some illustrative 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 should be understood that the present disclosure is not necessarily limited to application to specific standards and related protocols. On the contrary, the UE transceiver 230 and the base station transceiver 210 can be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.

[0048] According to various embodiments, for example, BS202 may be an evolved node B (eNB), a serving eNB, a target eNB, a femtocell or a microcell. In some embodiments, UE 204 may be embodied in various types of user equipment, such as a mobile phone, a smart phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, a wearable computing device, etc. Processor modules 214 and 236 may be implemented or completed with a general-purpose processor, a content addressable memory, a digital signal processor, an application specific integrated circuit, a field programmable gate array, any suitable programmable logic device, a discrete gate or transistor logic, a discrete hardware component, or any combination thereof for performing the functions described herein.

[0049] In addition, the steps of the methods or algorithms described in conjunction with the embodiments disclosed herein may be directly embodied in hardware, in firmware, in software modules executed by the processor modules 214 and 236, respectively, or in any practical combination thereof. The memory modules 216 and 234 may be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, removable disk, CD-ROM, or any other form of storage medium known in the art. In this regard, the memory modules 216 and 234 may be coupled to the processor modules 210 and 230, respectively, so that the processor modules 210 and 230 can read information from and write information to the memory modules 216 and 234, respectively. The memory modules 216 and 234 may also be integrated into their respective processor modules 210 and 230. In some embodiments, the memory modules 216 and 234 may each include a cache memory for storing temporary variables or other intermediate information during the execution of instructions executed by the processor modules 210 and 230, respectively. Memory modules 216 and 234 may also each include non-volatile memory for storing instructions to be executed by processor modules 210 and 230, respectively.

[0050] The network communication module 218 generally represents the hardware, software, firmware, processing logic and / or other components of the base station 202 that enable bidirectional communication 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 communication module 218 can be configured to support Internet or WiMAX services. In a typical deployment, but not limited to, the network communication module 218 provides an 802.3 Ethernet interface so that the base station transceiver 210 can communicate with a traditional Ethernet-based computer network. In this way, the network communication module 218 can include a physical interface for connecting to a computer network (e.g., a Mobile Switching Center (MSC)). The terms "configured for", "configured to" and their conjugates used herein for a specific operation or function refer to a device, component, circuit, structure, machine, signal, etc. that is physically constructed, programmed, formatted and / or arranged to perform a specific operation or function.

[0051] The Open Systems Interconnection (OSI) model (referred to herein as the "OSI model") is a conceptual and logical layout that defines network communications used by systems (e.g., wireless communication devices, wireless communication nodes) that are open to interconnecting and communicating with other systems. The model is divided into seven subcomponents or layers, each representing a conceptual set of services provided to the layers above and below it. The OSI model also defines a logical network and effectively describes computer packet transmissions by using different layer protocols. The OSI model may also be referred to as a seven-layer OSI model or a seven-layer model. In some embodiments, the first layer may be a physical layer. In some embodiments, the second layer may be a medium access control (MAC) layer. In some embodiments, the third layer may be a radio link control (RLC) layer. In some embodiments, the fourth layer may be a packet data convergence protocol (PDCP) layer. In some embodiments, the fifth layer may be a radio resource control (RRC) layer. In some implementations, the sixth layer may be a Non Access Stratum (NAS) layer or an Internet Protocol (IP) layer, and the seventh layer is another layer.

[0052] Various exemplary embodiments of the present solution are described below with reference to the accompanying drawings so that those of ordinary skill in the art can make and use the present solution. It is obvious to those of ordinary skill in the art that, 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. Therefore, the present solution is not limited to the exemplary embodiments and applications described and shown herein. In addition, the specific order or hierarchy of steps in the method disclosed herein is merely an exemplary method.

Therefore, it will be understood by those of ordinary skill in the art that the methods and techniques disclosed herein present various steps or actions in a sample order, and unless otherwise expressly stated, the present solution is not limited to the specific order or hierarchy presented.

[0053] 2. System and method for interference measurement of network nodes (eg, smart nodes (SN))

[0054] As certain systems (e.g., 5G new radio (NR), Next Generation (NG) systems, 3GPP systems, and / or other systems) move / transition to relatively higher / larger frequencies (e.g., approximately 4 GHz for FR1 deployments and over 24 GHz for FR2), this may observe / identify degradation in propagation (e.g., communication or transmission) conditions compared to relatively lower frequencies. In this case, it may be challenging to address propagation degradation caused by the use of relatively higher frequencies. Therefore, densification of cells (e.g., increasing density) may be required. In some cases, deployment of conventional full-stack cells may not be available (e.g., backhaul is not available) and / or may not be feasible, for example, when the deployment is preferred. In some systems, radio frequency (RF) repeaters with full-duplex amplification and forwarding operation can be used to provide comprehensive coverage in cellular network deployments. However, the use of RF repeaters may amplify signals and noise, which may increase interference in such systems.

[0055] In order to minimize or avoid noise amplification, a network-controlled repeater (NCR) can be introduced as an enhancement to traditional RF repeaters, with the ability to receive and / or process auxiliary control information from the network. The auxiliary control information can allow the network-controlled repeater to perform / perform / operate its amplification and forwarding operations in a more efficient manner. Certain benefits can include at least mitigating unnecessary noise amplification, transmission and reception with better spatial directionality, and / or simplifying network integration. For example, similar mechanisms or techniques for controlling signal (and / or noise) amplification can be performed by similar types of network devices discussed herein.

[0056] NCR can be regarded as a stepping stone for reconfigurable intelligent surface (RIS). RIS nodes can adjust the phase and amplitude of received signals to improve / enhance coverage (e.g., network communication coverage). As discussed herein, for simplicity, network nodes including but not limited to NCR, intelligent repeaters, enhanced RF repeaters, RIS and / or integrated access and backhaul IAB may be represented, referred to or set as intelligent nodes SN (e.g., network nodes). For example, SN may include, correspond to or refer to a network node to help BS102 improve coverage (e.g., avoid / avoid blockage / obstacles, increase transmission range, etc.). One or more SNs may be deployed to improve coverage, and some SN FUs may be activated (e.g., turned on) or deactivated (e.g., turned off), depending on whether there is a forwarding operation for the SN FU, for example, depending on whether there is at least one UE under the coverage area of ​​the SN.

[0057] In some cases, one or more SNs may be deployed to increase the data rate of UE 104. For example, UE 104 may establish a connection with BS 102 via a SN, where the SN may be an intermediary between UE 104 and BS 102. In this case, the SN may be used to increase the data rate (e.g., data transmission) of UE 104. It may be challenging to determine which SN is suitable for providing service to at least one UE 104 so that other SNs may be turned off to reduce potential interference and energy consumption. Therefore, in the case where multiple SNs are deployed in a particular area, the systems and methods of the technical solutions discussed herein may provide (or introduce) mechanisms and / or techniques to determine whether one or more SNs should provide service to one or more UE 104, so that an on / off command (e.g., a demand) may be sent to one or more SNs based on the determination.

[0058] Figure 3 Schematic diagram of an example network 300 is shown. Figure 3 As shown, one or more BSs 102A-B (e.g., BS 102) can provide services to one or more UEs 104A-B (e.g., UE 104) in their cells respectively via corresponding one or more SNs 306A-B (e.g., sometimes labeled as SN 306), for example, when there is congestion between BS 102 and UE 104. The system and method can provide SN 306, which is configured to measure signals transmitted / received / obtained from UE 104 to detect whether UE 104 is within the coverage area of ​​SN 306. In some cases, certain features or functions of SN 306 can be similar to UE 104. The system and method of the technical solution can provide various measurement configurations for UE 104 to measure signals of other UEs 104 (e.g., sounding reference signals (SRS) and other types of signals). For example, UE 104 can measure cross-link interference (CLI). The system and method (or network, e.g., BS 102 or SN 306) may configure UE 104 to report / provide / indicate CLI measurement information to at least one of SN 306 and / or BS 102 based on at least SRS resources. The CLI measurement information based on SRS resources may include at least one of the following:

[0059] · Measurement results for each SRS resource; and / or

[0060] SRS resource index.

[0061] In some cases, the network may configure UE 104 to report CLI measurement information based on a CLI received signal strength indicator (RSSI) resource, including at least one of the following:

[0062] · Measurement results for each CLI-RSSI resource; and / or

[0063] ·CLI-RSSI resource index.

[0064] In various implementations, the CLI measurement process may include multiple steps, such as steps 1 and 2 discussed herein. In step 1, BS 102 may configure UE 104 with a CLI measurement configuration. The measurement configuration may include at least one of the following parameters:

[0065] 1) The measurement object configured in the measObjectCLI-r16 information element (IE) The measurement object may indicate the frequency and / or time position of the SRS resources and / or RSSI resources to be measured by the UE 104 and / or the subcarrier spacing of the SRS resources.

[0066] 2) Report configuration configured in ReportConfigNR IE. A report configuration (e.g., sometimes referred to as a measurement report configuration) may include, correspond to, or be part of a list, wherein the list may include one or more report configurations for each measurement object. Each measurement report configuration may include / contain at least one of the following:

[0067] Reporting criteria: Criteria that may trigger the UE 104 to send measurement reports. 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 or at a predefined time after receiving the criteria).

[0068] Reference signal (RS) type: including or corresponding to SRS and / or

[0069] Or at least one of RSSI resources, etc.

[0070] Report format: can be used to configure the reported measurement results as reference signal received power (RSRP) values ​​and / or received signal strength indication RSSI values ​​and other types of values.

[0071] 3) Measurement identity (ID): used for measurement reporting. A list of measurement identities may be included, and each measurement identity in the list may link a measurement object with a corresponding report configuration.

[0072] 4) Quantity Configuration: The quantity configuration may indicate / define / represent measurement filter configuration for event assessment / determination and / or related reporting and / or periodic reporting of measurements.

[0073] In step 2, after receiving the configuration, the UE 104 may perform or execute a measurement operation. If at least one (eg, applicable) CLI measurement resource is to be reported, the UE 104 may initiate a reporting procedure / operation. For example:

[0074] 1) For each SRS resource included in measResultCLI, the associated SRS resource ID may be included in the report. For example, the SRS resource ID may be used to identify or represent an SRS resource. The SRS RSRP result may be included in the layer 3 filtered measurement result. In some cases, the SRS resource ID associated with the corresponding SRS RSRP result may be included in the layer 3 filtered measurement result in a decreasing / decreasing order, for example, the SRS resource with the highest / maximum interference (e.g., the SRS resource associated with the highest interference measurement) may be included in the list as the first SRS resource ID. In some other cases, the SRS resource ID associated with the corresponding SRS RSRP result may be included in the layer 3 filtered measurement result in an increasing / increasing order, for example, the SRS resource with the lowest / minimum interference may be included in the list as the first SRS resource ID.

[0075] 2) For each CLI-RSSI resource included in measResultCLI, the associated RSSI resource ID may be included in the report. For example, the RSSI resource ID may be used to identify or represent the CLI-RSSI resource. For example, based on the configuration of UE 104, the CLI RSSI results may be included in the layer 3 filtered measurement results, for example, in descending order (e.g., the CLI-RSSI resource with the largest interference may be included first) or in ascending order (e.g., the CLI-RSSI resource with the smallest interference may be included first).

[0076] refer to Figure 4, depicting a schematic diagram 400 of transmission links between BS 102 and SN 306 and between SN 306 and UE 104. SN 306 may include or consist of at least two units or functional parts / components (e.g., sometimes referred to as functional entities), such as a communication unit (CU) (e.g., SN CU) and a forwarding unit (FU) (e.g., SN FU). The units of SN 306 may support different functions of communicating with at least one of BS 102 and / or UE 104. In some cases, a first unit (or functional entity) of SN 306 may be referred to as SN CU, and a second unit (or functional entity) of SN 306 may be referred to as SN FU, or vice versa. For example, SN CU (e.g., first unit) may be a network controlled repeater NCR mobile terminal (MT). In another example, SN FU (e.g., second unit) may be an NCR forwarder / forwarding (Fwd). The SN CU may act / behave as or include features similar to those of the UE 104, for example, receiving and decoding auxiliary control information from the BS 102. The SN CU may be a control unit, a controller, a mobile terminal MT, a part of a UE, a third-party IoT device, etc. The SN FU may use the auxiliary control information received by the SN CU to perform intelligent amplification and forwarding operations. The SN FU may be a radio unit (RU), a RIS, etc.

[0077] like Figure 4 The transmission links shown between BS 102 and SN 306 and between SN 306 and UE 104 may be defined / described / provided as follows:

[0078] C1: Control link (C-link) from SN CU to BS;

[0079] C2: Control link (C-link) from BS to SN CU;

[0080] F1: backhaul link from SN FU to BS;

[0081] F2: backhaul link from BS to SN FU;

[0082] F3: Access link from UE to SN FU; and

[0083] F4: Access link from SN FU to UE.

[0084] A control link (e.g., sometimes referred to as a communication link) may refer to or describe that a signal from one side will be detected and decoded by the other side, so that information transmitted in / via the control link can be used to control the state of a forwarding link (e.g., a backhaul link and / or an access link, F-link). A forwarding link may mean that the SN FU is unaware of the signal from the BS 102 or UE 104. 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 a complete UL forwarding link (e.g., a backhaul link and an access link, respectively) from the UE 104 to the BS 102, where F1 is the SN FU UL forwarding link. Additionally, the F2 and F4 links may correspond to or be associated with a complete DL forwarding link (e.g., a backhaul link and an access link, respectively) from the BS 102 to the UE 104, where F4 is the SN FU DL forwarding link. The F1 and F2 links may correspond to or be referred to as a backhaul link, and the F3 and F4 links may correspond to or be referred to as an access link.

[0085] refer to Figure 5 , depicts a structure 500 of an example implementation for UE detection. The structure 500 may include or indicate various example implementations of the technical solutions discussed herein, including but not limited to, for example, a first example implementation, a second example implementation, and a third example implementation.

[0086] Example Implementation 1: BS configures SN to measure the signal from UE

[0087] In various implementations, BS 102 may configure / instruct SN 306 to measure signals from various UEs 104 to determine whether UE 104 is within the service area of ​​SN 306. Various aspects or configurations may be considered or utilized to measure signals from UE 104.

[0088] Example Aspect 1 of Example Implementation 1: Signal Type Measured by SN

[0089] In some aspects, for the SN 306 to perform measurement operations for detecting whether one or more UEs 104 are under the coverage area of ​​the SN 306 (e.g., providing service to the UE 104), the SN 306 may be configured to measure / analyze signals transmitted from / by the UE 104. In this case, at least one of the following example configurations (e.g., example configurations 1-3) or scenarios may be considered, performed, or utilized.

[0090] Example Situation 1 of Example Aspect 1

[0091] In various cases, the SN 306 may be transparent to the UE 104. For example, in these cases where the SN 306 is transparent to the UE 104, the UE 104 may display or follow conventional behaviors such that the UE 104 may operate normally (e.g., the UE 104 does not need to perform additional processes / steps). Considering different states or conditions of the UE 104 (e.g., the UE 104 is in different states or conditions), the following configurations or operations may be considered or performed:

[0092] Example Configuration 1 for Example Case 1

[0093] In some configurations, the signal to be measured by the SN 306 may 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 / instruct / designate the SN 306 to provide service to the UE 104 to improve / enhance the data rate (e.g., improve transmission / communication), the BS 102 may configure the SN 306 to measure the RS transmitted from the UE 104. The RS from the UE 104 may include at least one of an SRS, a demodulation reference signal (DM-RS), a phase tracking reference signal (PT-RS), and the like.

[0094] Example Configuration 2 for Example Case 1

[0095] 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 is operating in the RRC idle state, the UE 104 may send / 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 a cell-specific physical random access channel (PRACH) configuration used by one or more UEs 104. In this case, if the SN 306 measures the preamble from or provided by one or more UEs 104, the BS 102 may not be required to send / provide additional PRACH-related resource configurations to the SN 306, thereby reducing network traffic and / or resource consumption.

[0096] Example Configuration 3 for Example Case 1

[0097] In some configurations, the signal 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, and the UE 104 may send / transmit at least one PUCCH signal and / or PUSCH signal to the BS 102. Based on the PUCCH signal and / or the PUSCH signal, the BS 102 may configure the SN 306 with corresponding frequency-related information and / or time-related information for measurement (e.g., performing measurement of the signal).

[0098] Example Scenario 2 of Example Aspect 1

[0099] In various cases, the SN 306 may be opaque to the UE 104. In this case, the UE 104 may send at least one dedicated signal to the SN 306. For example, the signal may be dedicated / for the SN 306, so that when the SN 306 receives the signal, the SN 306 may determine its on / off state. In this example, the SN 306 may not report (or avoid reporting) the measurement results 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 sends the dedicated signal to the SN 306, the SN 306 may send the measurement results to the BS 102, for example, so 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:

[0103] In some configurations, the signal to be measured by the SN 306 may include a reference signal (RS) with a dedicated / specific configuration for UE detection. For example, a reference signal transmitted using a dedicated or specific port index may be used for UE detection. In another example, a reference signal transmitted using a dedicated or specific RS index may be configured for UE detection (e.g., configured for the SN 306 to perform UE detection or signal measurement). The signal measured by the SN 306 may include a reference signal (RS) with a dedicated / specific configuration for UE detection.

[0104] Example Configuration 3 for Example Case 2

[0105] In some configurations, the signal to be measured by the SN 306 may include a dedicated signal or sequence for UE detection. The dedicated sequence may include or correspond to at least one of the following: 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.

[0106] Example Configuration 4 for Example Case 2

[0107] 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.

[0111] In some configurations, the SN 306 may not need or require decoding of signals transmitted from the UE 104. In this case, the SN 306 may perform RSSI measurements on signals transmitted by / from the UE 104.

[0112] Example Configuration 2 for Example Aspect 2

[0113] In some configurations, the SN 306 may decode the corresponding signal transmitted by the UE 104. Subsequently, for the signal transmitted from / by the UE 104, 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 noise ratio (SINR) measurement, and / or a signal-to-interference ratio (SIR), and other measurements.

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

[0128] c. Subcarrier spacing (SCS).

[0129] d. Cell ID (e.g., index). In some implementations, the cell ID / index may 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. For example, if this parameter is not configured, the primary cell may be used as the default cell.

In this case, the threshold may include one or more specific values ​​for comparison with the measurement results. The specific value may be used by the SN 306 to determine whether to trigger a periodic report, for example, when the measurement result is greater than the threshold, the SN 306 may report the result.

[0140] b. In another example, if the report type is event triggered, then (e.g., current) events in the specification may be reused for measurement and / or new events may be defined for measurement.

[0158] 1) If the SN 306 is transparent to the UE 104, the measured preamble can be a traditional configuration for the random access procedure. Since the SN CU can perform or display similar features or functions as certain UEs 104, the SN CU can receive cell-specific PRACH-related configurations from the BS 102. In some implementations, the SN 306 can monitor during various PRACH opportunities to detect preambles sent by the UE 104. Additionally or alternatively, the BS 102 can indicate to the SN 306 whether the SN 306 is to monitor and / or measure preambles transmitted from the UE 104 during the PRACH opportunity. For example, the BS 102 can configure a new bit to the SN 306 to enable or disable the monitoring operation of the SN 306 during the PRACH opportunity.

[0164] 2) Through SI signal. One or more configurations may be configured by BS 102 via SI. In this case, the configuration of the measurement operation of SN 306 may be the same for each SN 306 in the cell.

[0165] 3) Through RRC signaling: One or more configurations may be configured through an RRC message.

[0166] 4) Through 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.

[0171] 9) Through OAM and DCI signals. One or more configurations may be configured by BS 102 via OAM signals. In some cases, one or more parameters of one or more configurations may be updated through or according to DCI signals.

[0172] 10) Through OAM and MAC CE signals. One or more configurations may be configured by BS 102 via OAM signals. In some cases, one or more configurations may be updated via MAC CE signals.

[0173] Example implementation 2: SN post-measurement operation

[0174] In various implementations, in response to or after receiving a configuration from BS 102 (e.g., for signal measurement), SN 306 may initiate measurement of signaling from UE 104 according to the configuration from BS 102. After the measurement (e.g., post-measurement), SN 306 may perform at least one of the following example configurations or operations.

[0175] Example Configuration 1 for Example Implementation 2

[0176] In some configurations, the SN 306 may directly determine the on / off state / condition (e.g., of the SN 306 itself). In various implementations, the determination of its on / off state may be based on or according to at least one of the following:

[0177] 1) The measurement result may be compared with one or more thresholds. Based on the result of the comparison, the SN 306 may determine its on / off state. For example, if the SN 306 is opaque to the UE 104, and the UE 104 sends a dedicated signal (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.) for measurement by the SN 306 / measured by the SN 306, 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 result value (e.g., the measurement result) with the threshold to determine its on / off state. For example, if the measurement result value exceeds / is greater than the threshold, the SN 306 may turn on or maintain the activity of the transmission and / or reception operation on at least one forwarding link. The one or more thresholds may be predefined for SN 306 and / or configured to SN 306 by BS 102 via at least one of RRC, MACCE and / or DCI signaling, as well as other types of signaling. In some cases, the one or more thresholds may be determined based on SN 306 capabilities.

[0178] 2) The on / off state may be determined by the number of detected signals. For example, UE 104 may send multiple dedicated sequences to SN 306, and SN 306 may count, identify, or determine the number of detected sequences. If the number of detected sequences exceeds / is greater than a specific value, SN 306 may determine to turn on. The specific value may be predefined for SN 306, and / or configured to SN 306 by BS 102 via at least one of RRC, MAC CE, and / or DCI signaling, as well as other types of signaling. In some cases, the specific value may be determined based on the capabilities of SN 306. In some implementations, the specific value may be the same or different for different signals.

[0179] 3) The on / off state may be determined based on whether a corresponding signal is detected. For example, UE 104 may send a dedicated PUSCH transmission to SN 306. If SN 306 detects the dedicated signal (e.g., a PUSCH transmission from UE 104), SN 306 may determine to turn on / activate. In some implementations, the dedicated signal sent from UE 104 to SN 306 may represent or correspond to a wake-up signal. In this case, when SN 306 receives a dedicated / specific signal of this type / kind, SN 306 may turn on. The specific / dedicated signal may be predefined for SN 306 and / or UE 104, and / or configured to SN 306 and / or UE 104 by BS 102 via at least one of RRC, MAC CE and / or DCI signaling and other types of signaling.

[0180] In some implementations, the SN 306 may report the on / off status to the BS 102, for example, after determining the on / off status of the SN 306. For example, in a relatively high data rate scenario, when the SN CU controls multiple SN FUs, if certain measurement results of the SN FUs do not (or cannot) meet / reach a threshold (e.g., predefined or predetermined), the SN CU may determine that the corresponding SN FU may not be suitable for providing services to 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, wherein the report may include information about / related to the set of SN FUs that are turned off / deactivated, for example, after determining that the corresponding SN FU may not be suitable for providing services to the UE 104.

[0181] In another example, if the measurement result of SN 306 does not meet the threshold, the SN CU may directly turn off the corresponding SN FU. In this example, if BS 102 does not receive information related to the measurement result from SN 306 (e.g., measured RSRP and / or RSSI values, and / or the on / off state of SN 306), BS 102 may determine that the corresponding SN FU is in the off state (e.g., deactivate SN 306).

[0182] Example Configuration 2 for Example Implementation 2

[0183] In some configurations, SN 306 may report measurement results to BS 102. The reported measurement results may include at least one of the following:

[0184] 1) One or more / multiple signal indexes.

[0185] 2) For each measurement signal, the content of the reported measurement result value may include or be at least one of the following:

[0186] a. Signal strength. The format of the signal strength may include at least one of RSRP, RSRQ, SINR, SIR, and / or RSSI, etc. For example, if beam information is not configured for the measurement signal (e.g., no beam information configuration), or only one beam configuration is configured for the measurement signal, the report result of the measurement signal may include a single signal strength.

[0187] b. The signal strength is the average strength calculated (or determined based on) among various beam-level signal strengths. The beam-level signal strength may be the signal strength measured by the SN 306 (e.g., a network node) using a specific beam. For example, if multiple beams are configured for the SN 306 for measuring signals, the report result of the corresponding measurement signal may include a signal strength value. The signal strength value may be a joint value or an average value determined using multiple beam-level signal strength values. In some implementations, the BS 102 may configure one or more thresholds for the SN 306 via at least one of RRC, MAC CE, and / or DCI signaling, etc. In some cases, the threshold may be configured to the SN 306 via OAM. The threshold may be used to compare with one or more beam-level signal strength values. In some implementations, one or more beam-level signal strength values ​​that are higher / greater than the threshold may be used to determine / calculate the reported signal strength value. In some implementations, the one or more configured thresholds for each measurement signal may be the same or different.

[0188] 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 report result of the corresponding measurement signal may include one or more signal strengths and / or one or more associated beam information. The signal strength and the associated beam information may be a one-to-one mapping. In some implementations, multiple pairs of report results may be included, where each pair may include 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 BS 102 to SN 306.

[0189] d. The strongest beam-level signal strength (eg, relatively highest signal strength value) among various beam-level signal strengths and / or associated beam information.

[0190] eN strongest beam-level signal strengths and / or corresponding N beam information. N may be the number of reported beam-level signal strengths. N may be configured to the SN 306 and / or the BS 102 via OAM. In some cases, N may be configured from the BS 102 to the SN 306 via at least one of RRC, MAC CE, DCI signaling, etc. For example, the BS 102 may configure the SN 306 to report only the top N strongest beam-level signal strength values. In this case, the SN 306 may report the top 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 may report various beam-level signal strength values ​​and / or associated beam information. In this case, the SN 306 may report only the strongest beam-level signal strength value and / or corresponding beam information.

[0191] f. An integer value determined based on a comparison between the measured signal strength and one or more threshold values.

[0192] i. For example, the RSRP value of the corresponding RS resource may be an integer value. In some cases, a predefined table may be used to map the measured numerical value to a historical or previously reported integer value in the measurement report. In some implementations, a current (e.g., existing) table may be reused, for example, a current SRS-RSRP measurement report mapping table may be reused. In some other implementations, a new table may be predefined / predetermined or configured for the SN 306.

[0193] ii. In another example, the reported result value may include or correspond to a measured signal state and / or a measured signal level, for example, obtained by comparing a signal strength value of a signal with a threshold. For example, the signal strength value used for comparison may be an original measurement value and / or a value obtained after the original value is processed via layer 1 filtering and / or layer 3 filtering and other types of filtering. In this example, one or more groups of thresholds may be configured / defined based on different measurement signals. In each group of thresholds, one or more thresholds may be defined to determine different measurement signal levels. For example, set 1 (e.g., a first set) may be used for SRS measurement, set 2 (e.g., a second set) may be used for preamble measurement, etc. In each set, different values ​​of the threshold may be used to determine different states / levels of the corresponding measurement signals, as shown in example Tables 1 and 2.

[0195] Example Table 1: Single Threshold for Measuring a Signal

[0196]

[0197]

[0198] Example Table 2: Three thresholds for each measured signal

[0199] iii. In some cases, one or more thresholds may be predefined for SN 306 or configured to SN 306 by BS 102 via at least one of RRC, MAC CE and / or DCI signaling, etc. In some other cases, one or more thresholds may be determined based on or according to the capabilities or compatibility / support of SN 306.

[0200] g. One or more integer values ​​determined based on 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 configured to the SN 306 by the BS 102 via at least one of RRC, MAC CE, and / or DCI signaling, etc. In some cases, the one or more thresholds may be determined based on the capabilities of the SN 306.

[0201] In some implementations, for example, the signal strength values ​​discussed above may include or be processed by layer 1 (L1) filtering and / or layer 3 (L3) filtering or other types of filtering. Given different techniques / mechanisms for reporting measurement result content, the SN 306 is configured such that the type of measurement result content reported to the BS 102 may be determined or selected according to the OAM of the SN 306 and / or BS 102, predefined for the SN 306 and / or BS 102, and / or determined by the BS 102 to the SN 306 via at least one of RRC, MAC CE, and / or DCI signaling, etc.

[0202] Example configuration 3 for example implementation 2

[0203] 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 coverage area of ​​the SN 306. For example, the indication provided by the SN 306 may include or correspond to a bit field. A bit value of 1 may indicate / represent the presence of one or more UEs 104 within the SN coverage area. A bit value of 0 may indicate that there are no UEs 104 within the SN coverage area. For example, depending on the configuration, a bit value of 0 may indicate that there are one or more UEs 104 within the SN coverage area, and a bit value of 1 may indicate that there are no UEs 104 within the SN coverage area.

[0204] In some implementations, if the SN CU controls multiple SN FUs and these SN FUs are located at different locations / places, the SN 306 may report to the BS 102 whether there are one or more UEs 104 under the coverage area of ​​each SN FU. For example, a bit field may be used to indicate whether one or more UEs 104 are under the coverage area of ​​the SN FU. The panel ID may be used to represent or indicate the SN FU information. In this case, one or more pairs (e.g., a bit field and a panel ID pair) {bit field, panel ID} may be used to indicate whether at least one UE 104 exists or resides under / within the coverage area of ​​the corresponding SN FU. In another example, a bitmap may be used to indicate whether one or more UEs 104 are under the coverage area of ​​each SN FU. For example, for the bitmap, each bit may be used to represent an SN FU. Depending on the configuration, a bit value of 1 (or 0) may indicate that there are one or more UEs 104 in the coverage area of ​​the corresponding SN FU, and a bit value of 0 (or 1) may indicate that there are no UEs 104 in the coverage area of ​​the corresponding SN FU.

[0205] In various arrangements, various information to be reported by the SN 306 to the BS 102 (e.g., as discussed above in Example Implementation 2) may be carried / transmitted / provided / transmitted via at least one of RRC, MAC CE, and / or uplink control information (UCI) signaling, etc. Additionally or alternatively, different parameters may be configured in the same signaling and / or in different signaling. For example, the indication may be carried in uplink control information UCI via transmission in a physical uplink control channel PUCCH or a physical uplink shared channel PUSCH, and / or carried in medium access control control unit MAC CE signaling via transmission in PUSCH.

[0206] Example Implementation 3: BS controls the on / off state of SN

[0207] In various implementations, BS 102 may be configured to control the on / off state of SN 306. After SN 306 ends / completes / performs a measurement operation, SN 306 may perform one or more other post-measurement operations, such as one or more operations or configurations described in connection with example implementation 2. After SN 306 performs another one or more post-measurement operations, the indication of the on / off state may include at least one of the following configurations.

[0211] 2) Group level on / off indication. For example, the BS 102 may indicate an on / off status to one or more SNs 306 in a group. In this case, the on / off indication may apply to one or more SNs 306 in a particular group, or may apply to one or more SN FUs controlled by the same SN CU.

[0212] 3) Beam level on / off indication. For example, BS 102 may indicate an on / off status of one or more beams applicable to SN 306. In this case, beam information and corresponding on / off status may be indicated (e.g., simultaneously or together) to SN 306. In some cases, the beam information may include or correspond to beam information of an access link and / or beam information of a backhaul link.

In some cases, the link information may include at least one of the following: 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).

[0214] 5) Panel level on / off indication. For example, BS 102 may indicate the on / off status of one or more panels applicable to SN 306. In this case, panel information and the corresponding on / off status may be indicated to SN 306. In some cases, the panel information may include or correspond to panel information of an access link and / or panel information of a backhaul link.

[0215] 6) Signal type level on / off indication. For example, BS 102 may indicate an on / off state applicable to one or more signal types. For example, BS 102 may indicate an off state to SN 306. The off state indication may be applicable (only) to UE-specific signal forwarding, while SN 306 may maintain / keep an on state for common signal forwarding operations.

[0216] 7) Port level on / off indication. For example, BS 102 may indicate the on / off status of one or more ports applicable to SN 306.

In some cases, the port information may include or correspond to port information of an access link and / or port information of a backhaul link.

[0217] 8) Band level on / off indication. For example, BS 102 may indicate the on / off status of one or more frequency bands applicable to SN 306.

If SN 306 receives beam information from BS 102, then the on / off state of SN 306 may be determined (e.g., implicitly) by, based on, or according to the beam information.

[0222] 2) If BS 102 does not have an explicit on / off status indication for SN 306, SN 306 may maintain the on status until SN 306 receives side control information from BS 102. If SN 306 receives beam information from BS 102, the on / off status of SN 306 may be determined (e.g., implicitly) based on the beam information.
