[0003] Introduction

[0004] Aspects of the present disclosure generally relate to wireless communication and relate to techniques and apparatus for communicating at least in part based on the mobility state of a network node.

[0005] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple access technology that is capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standards promulgated by the Third Generation Partnership Project (3GPP).

[0006] A wireless communication network may include a number of base stations (BSs) capable of supporting communication of several user equipments (UEs). A user equipment (UE) may communicate with a base station (BS) via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a B node, gNB, access point (AP), radio head, transmission reception point (TRP), New Radio (NR) BS, 5G B node, and so on.

[0007] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipments to communicate at the urban, national, regional, and even global levels. New Radio (NR), which may also be referred to as 5G, is an enhanced set of the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, improving services, utilizing new spectrums, and using Orthogonal Frequency Division Multiplexing with Cyclic Prefix (CP-OFDM) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., also referred to as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technology, and carrier aggregation to better integrate with other open standards. However, as the demand for mobile broadband access continues to grow, there is a need for further improvement of LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

[0031] Detailed Description

[0032] In some communication systems (such as 5G communication systems using multi-hop networks (e.g., integrated access and backhaul (IAB))), a central unit (CU) - distributed unit (DU) architecture may be used. For example, an IAB donor may be hierarchically connected to a group of IAB nodes, a group of UEs, etc. Each device in the network may generally be referred to as a network node.

[0033] Different network nodes can be associated with different mobility states, which can correspond to different mobility levels (e.g., different speeds at which the network node is traveling or capable of traveling). For example, an IAB donor can be configured as a stationary network node. In contrast, a UE can be a mobile network node and can be associated with a specific mobility level, such as a low mobility level (e.g., moving at a relatively low speed, such as pedestrian-based movement), a medium mobility level (e.g., moving at a relatively medium speed, such as car-based movement), or a high mobility level (e.g., moving at a relatively high speed, such as high-speed rail-based movement). An IAB node can be associated with a stationary mobility state, a mobile mobility state (e.g., low mobility level, medium mobility level, or high mobility level), etc.

[0034] Although some aspects are described in terms of a particular type of mobility state (e.g., stationary, low mobility, medium mobility, high mobility, etc.), other types of mobility states are also envisioned.

[0035] In some cases, a network node can change its mobility state. For example, a UE can transition from a high mobility level to a low mobility level based at least in part on, for example, the user of the UE exiting a high-speed rail transportation mode and continuing to use a pedestrian transportation mode. Similarly, when the moving speed of an IAB node is less than a threshold, the IAB node can transition from a mobile state to a stationary state. For example, when a car is moving, the IAB node in the car can have a medium mobility level, while when the car is parked, the IAB node can have a stationary mobility level. In this case, the threshold for distinguishing between the medium mobility level and the stationary mobility level can be a single threshold at a specific speed, multiple thresholds (e.g., a first threshold for transitioning from the medium mobility level to the low mobility level and a second threshold for transitioning from the low mobility level to the stationary mobility level), etc.

[0036] A network node (e.g., an IAB donor or an IAB node) can transmit an SSB transmission set (e.g., an SSB burst set) to cause another network node (e.g., an IAB node or a UE) to perform an initial access procedure, a cell selection procedure, a neighbor cell search procedure, a peer discovery procedure, a measurement procedure, etc. The SSB transmission can include information associated with the network node, such as a physical cell identifier (PCI) associated with the network node. In some cases, a mobile network node can travel into an area associated with another network node (e.g., a stationary network node). In such cases, the SSB transmissions of the mobile network node and the other network node may conflict. For example, the mobile network node and the other network node can be associated with the same PCI and can transmit SSB transmissions in the same resources, resulting in a PCI conflict and unsuccessful communication.

[0037] Some of the techniques and apparatuses described herein enable a network node to use specific resources for SSB transmission based on the mobility state of the network node (e.g., the mobility state of the cell associated with the network node). For example, a network node (e.g., an IAB node) may identify resources selected for transmitting an SSB based on the mobility state of the network node (e.g., the mobility state of the cell associated with the network node), and may transmit the SSB in the selected resources. In this way, mobile network nodes and stationary network nodes may use different resources (e.g., time resources and / or frequency resources) to transmit SSBs, thereby improving the avoidance of PCI conflicts and improving successful communication between the network nodes.

[0038] Aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be implemented in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice a method. Additionally, the scope of the present disclosure is intended to cover such apparatus or methods practiced using other structures, functionality, or a combination of structures and functionality that supplement or are additional to the aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be implemented by one or more elements of a claim.

[0039] Certain aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in detail hereinafter and illustrated in the drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0040] It should be noted that although aspects herein may be described using terms typically associated with 3G and / or 4G wireless technologies, aspects of the present disclosure may be applied in communication systems based on other generations (such as 5G and later generations, including NR technologies).

[0041] Figure 1FIG. 0 is a diagram illustrating a wireless network 100 in which aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network, a 5G or NR network, etc. The wireless network 100 may include several BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with user equipment (UE) and may also be referred to as a base station, NR BS, B node, gNB, 5G B node (NB), access point, transmission reception point (TRP), etc. Each BS provides communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0042] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unconstrained access by UEs having a service subscription. A pico cell may cover a relatively small geographic area and may allow unconstrained access by UEs having a service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow constrained access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). The BS for a macro cell may be referred to as a macro BS. The BS for a pico cell may be referred to as a pico BS. The BS for a femto cell may be referred to as a femto BS or a home BS. In the Figure 1 example shown in FIG. 5, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0043] In some examples, a cell may not have to be stationary, and the geographic area of a cell may move according to the location of a mobile BS. In some examples, BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as direct physical connections, virtual networks, and / or analogs using any suitable transport network.

[0044] The wireless network 100 may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send the transmission of the data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. In Figure 1 the example shown in, relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station can also be referred to as a relay BS, relay base station, relay, etc.

[0045] The wireless network 100 can be a heterogeneous network that includes different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0046] UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. A UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, a superbook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via wireless or wired media.

[0047] Some UEs may be considered machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to a network (e.g., a wide area network such as the Internet or a cellular network) or provide connectivity to the network via a wired or wireless communication link, for example. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as narrowband IoT (NB-IoT) devices. Some UEs may be considered customer premise equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, etc.

[0048] In general, any number of wireless networks may be deployed in a given geographical area. Each wireless network may support a specific RAT and may operate on one or more frequencies. The RAT may also be referred to as a radio technology, an air interface, etc. The frequency may also be referred to as a carrier, a frequency channel, etc. Each frequency may support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network may be deployed.

[0049] As Figure 1 shown, BS 110 (e.g., a central unit (CU) or an IAB donor such as BS 110a) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may provide means for identifying one or more resources for transmitting one or more SSBs, the one or more resources being associated with the mobility state of BS 110; and means for transmitting the one or more SSBs in the one or more resources. In some aspects, as described in more detail elsewhere herein, the communication manager 140 may provide means for selecting one or more resources for an IAB node to transmit one or more SSBs, the one or more resources being associated with the mobility state of the IAB node; and means for transmitting an indication of the one or more resources to enable the IAB node to use the one or more resources to transmit the one or more SSBs. Additionally or alternatively, the communication manager 140 may provide means for performing one or more other operations described herein.

[0050] Similarly, BS 110 (e.g., a distributed unit (DU), a relay, or an IAB node, such as BS 110d) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may provide means for identifying one or more resources for transmitting one or more SSBs, the one or more resources being associated with the mobility state of BS 110; and means for transmitting the one or more SSBs in the one or more resources. In some aspects, as described in more detail elsewhere herein, the communication manager 150 may provide means for identifying one or more resources for receiving one or more SSBs, the one or more resources being associated with the mobility state of an IAB node; and means for receiving the one or more SSBs from the IAB node in the one or more resources. Additionally or alternatively, the communication manager 150 may provide means for performing one or more other operations described herein.

[0051] Similarly, UE 120 (e.g., UE 120e) may include a communication manager 160. As described in more detail elsewhere herein, the communication manager 160 may provide means for identifying one or more resources for receiving one or more SSBs, the one or more resources being associated with the mobility state of an IAB node; and means for receiving the one or more SSBs from the IAB node in the one or more resources. Additionally or alternatively, the communication manager 160 may provide means for performing one or more other operations described herein.

[0052] As indicated above, Figure 1 is provided merely as an example. Other examples may be different from the example(s) described with respect to Figure 1 which are described.

[0053] Figure 2 FIG. 200 is a block diagram showing the design of a base station 110 (e.g., a network node) and a UE 120 (e.g., a network node), where the base station 110 and the UE 120 may be Figure 1 one of each of the base stations and one of each of the UEs in. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, where generally T≥1 and R≥1.

[0054] At base station 110, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCSs) for a UE at least in part based on channel quality indicators (CQIs) received from each UE, process (e.g., encode and modulate) data for the UE at least in part based on the MCSs selected for each UE, and provide data symbols for all UEs. Transmit processor 220 may provide means for transmitting data or control information, such as to UE 120, for example. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRSs)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process its respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively. According to various aspects described in more detail below, position coding may be utilized to generate synchronization signals to convey additional information.

[0055] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 and / or other base stations and may provide the received signals to demodulators (DEMOD) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 may obtain the received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols when applicable, and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The controller / processor 280 may provide the UE 120 with means for determining, identifying, or selecting, etc., such as using a determination circuit, an identification circuit, a selection circuit, etc. The receive processor 258 may provide the UE 120 with means for receiving data or control information, etc., from, for example, the BS 110. The channel processor may determine a reference signal received power (RSRP), a received signal strength indicator (RSSI), a reference signal received quality (RSRQ), a channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 120 may be included in a housing.

[0056] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may provide the UE 120 with means for transmitting data or control information, etc., to, for example, the BS 110. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266 when applicable, further processed by the modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, the uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 when applicable, and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the BS 110 with means for receiving data or control information, etc., from, for example, the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The controller / processor 240 may provide means for, for example, determining, selecting, identifying, or detecting, etc. The base station 110 may include a communication unit 244.

[0057] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 any other component(s) thereof may perform one or more techniques associated with selecting SSB resources according to the mobility state, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 any other component(s) thereof may execute or direct, for example Figure 5 process 500, Figure 6 process 600, Figure 7 process 700, and / or the operations of other processes as described herein. The memories 242 and 282 may store data and program codes for the base station 110 and the UE 120, respectively. The scheduler 246 may schedule the UEs for data transmission on the downlink and / or uplink.

[0058] In some aspects, the UE 120 (e.g., a network node, etc.) may include: means for identifying, e.g., using the controller / processor 280, the memory 282, etc., one or more resources for receiving one or more SSBs, the one or more resources being associated with the mobility state of the IAB node; means for receiving, e.g., using the antenna 252, the DEMOD 254, the MIMO detector 256, the receiving processor 258, the controller / processor 280, etc., the one or more SSBs in the one or more resources from the IAB node; and so on. Additionally or alternatively, the UE 120 may include means for performing one or more other operations described herein. In some aspects, such means may include the communication manager 160. Additionally or alternatively, such means may include one or more components of the UE 120 described in conjunction with Figure 2 the UE 120.

[0059] In some aspects, the base station 110 (e.g., a network node, an IAB node, an IAB donor, etc.) may include: means for identifying, e.g., using the controller / processor 240, the memory 242, etc., one or more resources for transmitting one or more SSBs, the one or more resources being associated with the mobility state of the base station 110; means for transmitting, e.g., using the controller / processor 240, the transmitting processor 220, the TX MIMO processor 230, the MOD 232, the antenna 234, etc., the one or more SSBs in the one or more resources; means for identifying, e.g., using the controller / processor 240, the memory 242, etc., one or more resources for receiving one or more SSBs, the one or more resources being associated with the mobility state of the IAB node; means for receiving, e.g., using the antenna 234, the DEMOD 232, the MIMO detector 236, the receiving processor 238, the controller / processor 240, etc., the one or more SSBs in the one or more resources from the IAB node; and so on. Additionally or alternatively, the base station 110 may include means for performing one or more other operations described herein. In some aspects, such means may include the communication manager 150. In some aspects, such means may include one or more components of the base station 110 described in conjunction with Figure 2 the base station 110.

[0060] In some aspects, the base station 110 (e.g., a network node, an IAB donor, etc.) may include: means for selecting, for an IAB node (e.g., using the controller / processor 240, the memory 242, etc.), one or more resources for transmitting one or more SSBs, the one or more resources being associated with the mobility state of the IAB node; means for transmitting (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the MOD 232, the antenna 234, etc.) an indication of the one or more resources so that the ISB node can use the one or more resources to transmit the one or more SSBs; means for identifying (e.g., using the controller / processor 240, the memory 242, etc.) one or more resources for transmitting one or more SSBs, the one or more resources being associated with the mobility state of the base station 110; means for transmitting (e.g., using the controller / processor 234, the transmit processor 220, the TX MIMO processor 230, the MOD 232, the antenna 234, etc.) the one or more SSBs in the one or more resources; and so on. Additionally or alternatively, the base station 110 may include means for performing one or more other operations described herein. In some aspects, such means may include the communication manager 140. In some aspects, such means may include one or more components of the base station 110 described in conjunction with Figure 2 the base station 110.

[0061] As indicated above, Figure 2 is provided merely by way of example. Other examples may be different from the examples described with respect to Figure 2 the examples described.

[0062] Figure 3A and 3B are diagrams illustrating an example 300 of a network topology for a network according to various aspects of the present disclosure. Self-backhaul or IAB may be deployed to use a common resource set for access traffic and backhaul traffic. For example, a first wireless node (e.g., BS 110a, BS 110d, etc.) may communicate backhaul traffic (e.g., SSB) with a second wireless node and may communicate access traffic (e.g., SSB) with a third wireless node. Although some aspects described herein are described in the form of an IAB deployment, some aspects described herein may be used in conjunction with other types of multi-hop networks.

[0063] As Figure 3AAs shown, Example 300 may include a plurality of wireless nodes 302 (e.g., BSs) and a plurality of wireless nodes 304 (e.g., UEs). At least one wireless node (e.g., wireless node 302-1, which may be a CU (such as BS 110a)) may communicate with the core network via a backhaul link 306 (such as a fiber optic connection, a wireless backhaul connection, a combination thereof, etc.). The wireless nodes 302 and 304 may communicate with each other using a link set 308 (such as a millimeter wave (mmWave) link set; 3G, 4G, 5G, etc. air interfaces; any future wireless network (e.g., 6G wireless network); etc.). The wireless node 302 (which may be a network node) may be associated with different mobility states (such as a stationary mobility state, a mobile mobility state (e.g., a high mobility level, a low mobility level, etc.)).

[0064] As Figure 3A As further shown, one or more of the wireless nodes 302 or 304 may communicate indirectly via one or more other wireless nodes 302 or 304. For example, data may be transferred from the core network to the wireless node 304-4 via the backhaul link 306, a link 308 between the wireless node 302-1 (e.g., BS 110a) and the wireless node 302-5 (e.g., which may be a DU (such as BS 110d)), and a link 308 between the wireless node 302-5 and the wireless node 304-4 (e.g., which may be a UE (such as UE 120e)).

[0065] As Figure 3BAs shown, wireless nodes 302 and 304 can be arranged in a hierarchical topology to achieve management of network resources. Each link 308 can be associated with a primary link endpoint (primary LEP, which can also be referred to as serving LEP, control / controller LEP, primary LEP, main LEP, management LEP, control and management LEP, etc.) and a secondary link endpoint (secondary LEP, which can also be called served LEP, controlled / controlled party LEP, subordinate LEP, auxiliary LEP, managed LEP, controlled and managed LEP, etc.), which can define the hierarchy between wireless nodes 302 or 304. For example, wireless node 302-6 (e.g., which can be a CU such as BS 110a) can communicate with wireless node 302-7 (e.g., which can be a DU such as BS110d, and the DU is a child node or subordinate node of wireless node 302-6) via link 308-1 (which can be the parent link of wireless node 302-7). In this case, wireless node 302-6 can provide configuration information, such as communication configuration, rules for determining communication configuration, etc. Additionally or alternatively, wireless node 302-6 can provide information about the mobility status of the child nodes of wireless node 302-7 (e.g., at least partially based on mobility information received from the core network). Similarly, wireless node 302-7 can communicate with wireless node 304-7 (e.g., which can be a UE such as UE 120e, and the UE can be a child node or subordinate node of wireless node 302-7) via link 308-2 (which can be a sub-link of wireless node 302-7). In this case, wireless node 302-6 can schedule wireless node 302-7, and wireless node 302-7 can schedule wireless node 304-7 at least partially based on the hierarchy defined herein.

[0066] As indicated above, Figure 3A and 3B are provided as examples. Other examples are possible and can be different from the examples regarding Figure 3A and 3B described.

[0067] Figure 4 is a diagram illustrating example 400 of selecting SSB resources according to mobility status in accordance with various aspects of the present disclosure. As Figure 4 shown, example 400 can include BS 110a (e.g., CU), BS 110d (e.g., DU), and UE 120e. In some aspects, BS 110a can be an IAB donor and BS 110d can be an IAB node. In some aspects, the actions performed by UE 120e as described herein can be performed by BS 110d (e.g., the mobile termination component of the IAB node).

[0068] AsFigure 4 As shown by reference numeral 410, BS 110d may provide an indication of the mobility state of BS 110d (e.g., the mobility state of the cell associated with BS 110d) to BS 110a. For example, BS 110d may transmit information identifying the mobility state of BS 110d. As another example, BS 110d may transmit information such as speed, location, etc. of BS 110d so that BS 110a can identify the mobility state of BS 110d. In some aspects, BS 110a may be configured with information identifying the mobility state of BS 110d.

[0069] The mobility state may be a stationary mobility state or a mobile mobility state. The mobile mobility state may be a high-speed mobility state, a medium-speed mobility state, a low-speed mobility state, etc. In some aspects, the stationary mobility state may be associated with a speed of zero, and the mobile mobility state may be associated with a speed greater than zero. In some aspects, the low-speed mobility state may be associated with a speed lower than a first threshold and greater than zero, the medium-speed mobility state may be associated with a speed between the first threshold and a second threshold, and the high-speed mobility state may be associated with a speed higher than the second threshold.

[0070] In some aspects, the mobility state of BS 110d may be the initial mobility state of BS 110d. Alternatively, the mobility state of BS 110d may be the new mobility state of BS 110d. For example, BS 110d may transition from a stationary mobility state to a mobile mobility state or from a high-speed mobility state to a low-speed mobility state. Accordingly, the indication of the mobility state provided by BS 110d may indicate a change in the mobility state of BS 110d.

[0071] As shown by reference numeral 420, BS 110a may select one or more resources (e.g., one or more resources in which BS 110d is to transmit the SSB) for BS 110d based on the mobility state of BS 110d. For example, BS 110a may select one or more resources for BS 110d at least in part based on the indication of the mobility state provided by BS 110d. BS 110a may select resources for BS 110d that do not conflict with the resources selected for another BS (e.g., another BS 110d) having a different mobility state than BS 110d.

[0072] In some aspects, BS 110d may not provide an indication of the mobility state to BS 110a, and BS 110d may select one or more resources (e.g., for transmitting SSB) according to the mobility state of BS 110d. In this case, BS 110d (e.g., the operation, administration, and maintenance (OAM) component of BS 110d) may select resources according to the criteria defined for the mobility state of BS 110d to avoid selecting resources that conflict with the resources selected by another BS (e.g., another BS 110d) having a mobility state different from that of BS 110d.

[0073] In some aspects, one of BS 110a or BS 110d may be selected to select resources at least partially based on the type of SSB to be transmitted in the selected resources. For example, the resources to be used by BS 110d for transmitting SSBs related to neighbor measurement or peer discovery (collectively referred to as radio resource management (RRM) SSBs herein) may be selected by BS 110a. As another example, the resources to be used by BS 110d for transmitting cell definition SSBs (CD-SSBs) may be selected by BS 110d.

[0074] In some aspects, the selected resources may be associated with a stationary mobility state or a mobile mobility state. For example, if BS 110d has a stationary mobility state, the selected resources may be associated with the stationary mobility state. As another example, if BS 110d has a mobile mobility state, the selected resources may be associated with the mobile mobility state. In some aspects, the selected resources may be associated with the type of mobile mobility state. For example, the selected resources may be associated with a low mobility state, a medium mobility state, a high mobility state, and so on.

[0075] In some aspects, the resources selected for the stationary mobility state may be in a different synchronization (sync) grid from the resources selected for the mobile mobility state. For example, a first set of resources and a second set of resources that may be used by BS 110d for transmitting CD-SSBs may be in different synchronization grids according to the mobility state of BS 110d. In some aspects, the first synchronization grid may be assigned to (e.g., dedicated to) the stationary mobility state, and the second synchronization grid may be assigned to (e.g., dedicated to) the mobile mobility state.

[0076] In some aspects, the resources selected for the stationary mobility state may have a different periodicity and / or a different time offset from the resources selected for the mobile mobility state. For example, the first resource set and the second resource set that can be used by BS 110d to transmit CD-SSBs may have different periodicities and / or time offsets (e.g., the first resource set may be time-division multiplexed with the second resource set) in the same synchronization raster according to the mobility state of BS 110d. In some aspects, the first periodicity and / or the first time offset may be assigned to the stationary mobility state, and the second periodicity and / or the second time offset may be assigned to the mobile mobility state.

[0077] In some aspects, the resources selected for the stationary mobility state may have a different SSB measurement timing configuration (SMTC) window or a different SSB transmission configuration (STC) window from the resources selected for the mobility state. For example, the first resource set and the second resource set that can be used by BS110d to transmit RRM SSBs may be associated with different SMTC windows and / or STC windows according to the mobility state of BS 110d. In some aspects, the first SMTC window and / or the first STC window may be assigned to the stationary mobility state, and the second SMTC window and / or the second STC window may be assigned to the mobile mobility state.

[0078] In some aspects, the SMTC window and / or the STC window associated with the stationary mobility state and the SMTC window and / or the STC window associated with the mobile mobility state may be orthogonal in time and / or orthogonal in frequency. In some aspects, the SMTC of the SMTC window associated with the stationary mobility state and / or the STC of the STC window may be different from the SMTC of the SMTC window associated with the mobile mobility state and / or the STC of the STC window (e.g., the respective SMTCs may overlap, but identify different time and / or frequency window positions, different window durations, etc.). For example, the SMTC of the SMTC window associated with the stationary mobility state and / or the STC of the STC window may identify a PCI list and / or a periodicity that is different from the PCI list and / or the periodicity identified by the SMTC of the SMTC window associated with the mobile mobility state and / or the STC of the STC window.

[0079] As indicated by reference numeral 430, BS 110a may provide an indication of the selected resource to BS 110d. This indication may enable BS 110d to identify the selected resource for transmitting the SSB. In some aspects, such as when BS 110d selects (e.g., identifies) a resource, BS 110d may provide an indication of the selected resource to BS 110a. In some cases, this indication may provide a notification of the selected resource to BS 110a (e.g., to enable BS 110a to avoid selecting the same resource for another BS with a different mobility state). Additionally or alternatively, this indication may request BS 110a to assign the selected resource to BS 110d. In this case, BS 110a may assign the selected resource to BS 110d (e.g., if the resource does not conflict with the resource selected for another BS with a different mobility state) and transmit an indication to BS 110d that the selected resource has been assigned to BS 110d.

[0080] As indicated by reference numeral 440, BS 110d may transmit the SSB in the selected resource and UE 120e may receive these SSBs in the selected resource. In some aspects, the SSB may be associated with cell access, cell selection, cell reselection, etc., such as CD-SSB. For example, BS 110d may transmit CD-SSB according to a synchronization raster associated with the mobility state of BS 110d (e.g., the mobility state of the cell associated with BS 110d), and UE 120e may receive these CD-SSBs according to this synchronization raster. That is, BS 110d may transmit CD-SSB in the selected resource that corresponds to the synchronization raster associated with the mobility state of BS 110d. As another example, BS 110d may transmit CD-SSB according to a periodicity and / or time offset associated with the mobility state of BS 110d (e.g., the mobility state of the cell associated with BS 110d), and UE 120e may receive these CD-SSBs according to this periodicity and / or time offset. That is, BS 110d may transmit CD-SSB in the selected resource that corresponds to the periodicity and / or time offset associated with the mobility state of BS 110d.

[0081] In some aspects, the SSB may be associated with neighbor search, peer discovery, neighbor measurement, etc., such as RRM SSB. For example, BS 110d may transmit RRM SSB in an STC window associated with the mobility state of BS 110d. That is, BS 110d may transmit RRM SSB in the selected resources corresponding to the STC window associated with the mobility state of BS 110d. In addition, UE 120e may receive RRM SSB in an SMTC window associated with the mobility state of BS 110d (e.g., an SMTC window corresponding to the STC window used for transmitting the SSB).

[0082] In this way, when a mobile network node (e.g., BS 110d) and a stationary network node are in the same area and using the same PCI simultaneously, PCI conflicts can be avoided. In addition, using different resources for the stationary mobility state and the mobile mobility state (e.g., partitioning the SSB space at least partially based on the mobility state) allows the mobile network node and the stationary network node to be configured differently (e.g., different configurations for beam sweep periodicity, beam width, etc.) while avoiding interference. In addition, using different resources (e.g., STC window and / or SMTC window) for the stationary mobility state and the mobile mobility state allows the mobile network node and the stationary network node to use different PCI lists (e.g., neighbor PCI lists). For example, the STC and / or SMTC of the stationary network node may identify a static PCI list, and the STC and / or SMTC of the mobile network node may not identify a PCI list or may identify a dynamic PCI list updated based on the movement of the mobile network node.

[0083] As shown by reference numeral 450, UE 120e may identify the mobility state of BS 110d at least partially based on the resources used by BS 110d for transmitting the SSB and / or the resources in which UE 120e receives the SSB. For example, UE 120e may identify the mobility state of BS 110d at least partially based on the synchronization raster associated with the resources in which UE 120e receives the SSB. As another example, UE 120e may identify the mobility state of BS 110d at least partially based on the periodicity and / or time offset associated with the resources in which UE 120e receives the SSB. As a further example, UE 120e may identify the mobility state of BS 110d at least partially based on the SMTC window associated with the resources in which UE 120e receives the SSB.

[0084] In some aspects, UE 120e may be configured with information that enables UE 120e to identify a particular mobility state associated with a particular synchronization grid, periodicity, time offset, SMTC window, etc. For example, the information may indicate that the stationary mobility state is associated with a first time offset and the mobile mobility state is associated with a second time offset.

[0085] In some aspects, UE 120e may receive an SSB from a BS in a particular mobility state. For example, UE 120e may determine to receive an SSB from a BS with a stationary mobility state (e.g., to communicate via a stationary BS), and may monitor the SSB in resources associated with the stationary mobility state. As another example, UE 120e may determine to receive an SSB from a BS with a mobile mobility state, and may monitor the SSB in resources associated with the mobile mobility state.

[0086] In some aspects, UE 120e may perform measurements on the received SSB as part of an initial access procedure, a cell reselection procedure, a neighbor cell search procedure, a peer discovery procedure, a measurement procedure, etc. In some aspects, UE 120e may transmit a measurement report based on the measurements of the received SSB. For example, UE 120e may transmit a measurement report to BS 110d that identifies one or more measurements of the SSB (e.g., reference signal received power (RSRP) measurement, reference signal received quality (RSRQ) measurement, signal-to-noise ratio (SNR) measurement, signal-to-interference plus noise ratio (SINR) measurement, etc.). In some aspects, UE 120e may be configured with different measurement configurations for the stationary mobility state and the mobile mobility state. For example, if BS 110d has a mobile mobility state, the measurement configuration may identify that UE 120e is to report measurements more frequently, and if BS 110d has a stationary mobility state, the measurement configuration may identify that UE 120e is to report measurements less frequently.

[0087] Figure 5 FIG. is an illustration of an example process 500, such as may be performed by a network node, in accordance with various aspects of the present disclosure. Example process 500 is an example in which a network node (e.g., BS 110d, UE 120e, IAB node, apparatus 800, apparatus 900, apparatus 1000, etc.) performs operations associated with selecting SSB resources based on a mobility state.

[0088] As Figure 5As shown, in some aspects, process 500 may include: identifying one or more resources for receiving one or more SSBs, the one or more resources being associated with the mobility state of the IAB node (block 510). For example, a network node (e.g., using antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, identification / selection component 808, etc.) may identify one or more resources for receiving one or more SSBs, the one or more resources being associated with the mobility state of the IAB node, as described above.

[0089] In some aspects, process 500 may include: identifying the mobility state of the IAB node at least in part based on the one or more resources (block 512). For example, a network node (e.g., using controller / processor 280, memory 282, identification / selection component 808, etc.) may identify the mobility state of the IAB node at least in part based on the one or more resources, as described above.

[0090] As Figure 5 Further shown, in some aspects, process 500 may include: receiving the one or more SSBs from the IAB node in the one or more resources (block 520). For example, a network node (e.g., using antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, receive component 802, etc.) may receive the one or more SSBs from the IAB node in the one or more resources, as described above.

[0091] As Figure 5 Further shown, in some aspects, process 500 may include: performing measurements on the one or more SSBs (block 530). For example, a network node (e.g., using controller / processor 280, memory 282, measurement component 810, etc.) may perform measurements on the one or more SSBs, as described above.

[0092] Process 500 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in connection with one or more other processes described elsewhere herein.

[0093] In a first aspect, the one or more SSBs are received as part of at least one of an access procedure, a cell selection procedure, a measurement procedure, or a peer discovery procedure.

[0094] In a second aspect, either alone or in combination with the first aspect, the one or more resources are one or more first resources associated with a first mobility state or one or more second resources associated with a second mobility state. In a third aspect, either alone or in combination with one or more of the first and second aspects, the first mobility state is a stationary mobility state and the second mobility state is a mobile mobility state.

[0095] In a fourth aspect, either alone or in combination with one or more of the first to third aspects, the one or more resources are received according to a first synchronization raster associated with the first mobility state or a second synchronization raster associated with the second mobility state.

[0096] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the one or more resources are received according to a first SMTC window associated with the first mobility state or a second SMTC window associated with the second mobility state. In a seventh aspect, either alone or in combination with one or more of the first to sixth aspects, the first SMTC window is orthogonal in time and / or in frequency to the second SMTC window. In an eighth aspect, either alone or in combination with one or more of the first to seventh aspects, the SMTC of the first SMTC window identifies at least one of a first PCI list or a first periodicity, and the first PCI list or the first periodicity is different from a second PCI list or a second periodicity identified by the SMTC of the second SMTC window.

[0097] In a ninth aspect, either alone or in combination with one or more of the first to eighth aspects, the one or more resources are identified as being associated with a mobility state at least in part based on a synchronization raster associated with the one or more resources.

In an eleventh aspect, either alone or in combination with one or more of the first to tenth aspects, the one or more resources are identified as being associated with a mobility state at least in part based on an SMTC window associated with the one or more resources.

[0098] Although Figure 5 illustrates example blocks of process 500, in some aspects, process 500 may include Figure 5fewer boxes, different boxes, or boxes arranged differently than the boxes depicted therein. Additionally or alternatively, two or more boxes of process 500 may be executed in parallel.

[0099] Figure 6 is a diagram illustrating an example process 600, performed, for example, by a network node, in accordance with various aspects of the present disclosure. Example process 600 is an example in which a network node (e.g., BS 110a, BS 110d, IAB node, IAB donor, apparatus 800, apparatus 900, apparatus 1000, etc.) performs operations associated with selecting SSB resources according to a mobility state.

[0100] As Figure 6 shown in, in some aspects, process 600 may include: identifying one or more resources for transmitting one or more SSBs, the one or more resources being associated with a mobility state of an IAB node (block 610). For example, a network node (e.g., using controller / processor 240, memory 242, identification / selection component 808, etc.) may identify one or more resources for transmitting one or more SSBs, the one or more resources being associated with a mobility state of an IAB node, as described above.

[0101] In some aspects, process 600 may include: selecting the one or more resources (block 612). For example, a network node (e.g., using controller / processor 240, memory 242, identification / selection component 808, etc.) may select the one or more resources, as described above. In some aspects, process 600 may include: receiving information identifying the one or more resources from another network node (block 614). For example, a network node (e.g., using antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, receive component 802, etc.) may receive information identifying the one or more resources from another network node, as described above.

[0102] As Figure 6 further shown in, in some aspects, process 600 may include: transmitting the one or more SSBs in the one or more resources (block 620). For example, a network node (e.g., using transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, controller / processor 240, transmit component 804, etc.) may transmit the one or more SSBs in the one or more resources, as described above.

[0103] Process 600 may include additional aspects, such as any individual aspect or any combination of aspects described below and / or in connection with one or more other processes described elsewhere herein.

[0104] In a first aspect, the one or more SSBs are associated with at least one of cell access, cell selection, neighbor measurement, or peer discovery.

[0105] In a second aspect, either alone or in combination with the first aspect, the one or more resources are one or more first resources associated with a first mobility state or one or more second resources associated with a second mobility state. In a third aspect, either alone or in combination with one or more of the first and second aspects, the first mobility state is a stationary mobility state and the second mobility state is a mobile mobility state.

[0106] In a fourth aspect, either alone or in combination with one or more of the first to third aspects, the one or more resources are transmitted according to a first synchronization raster associated with the first mobility state or a second synchronization raster associated with the second mobility state. In a fifth aspect, either alone or in combination with one or more of the first to fourth aspects, the one or more resources are transmitted according to at least one of a first periodicity or a first time offset associated with the first mobility state or at least one of a second periodicity or a second time offset associated with the second mobility state.

[0107] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the one or more resources are transmitted in a first STC window associated with the first mobility state or a second STC window associated with the second mobility state.
