[0004] introduction

[0005] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for communicating based at least in part on the mobility state of a network node.

[0006] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple access technologies 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 a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0007] A wireless communication network may include several base stations (BSs) capable of supporting communications for several user equipment (UEs). User equipment (UEs) may communicate with the base stations (BSs) via downlinks and uplinks. The downlink (or forward link) refers to the communication link from the BS to the UE, while 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 Node B, gNB, access point (AP), radio head, transmit reception point (TRP), new radio (NR) BS, 5G Node B, and so on.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known 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 for better integration with other open standards. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that adopt these technologies. Overview

[0030] In some communication systems, such as 5G communication systems using a multi-hop network (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, and so on. Each device in the network may generally be referred to as a network node.

[0031] Different network nodes may be associated with different mobility states, which may correspond to different mobility levels (e.g., different speeds at which the network node is traveling or is capable of traveling). For example, an IAB donor may be configured as a stationary network node. In contrast, a UE may be a mobile network node and may be associated with a particular 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 automobile-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 may be associated with a stationary mobility state, a mobile mobility state (e.g., a low mobility level, a medium mobility level, or a high mobility level), etc.

[0032] Although some aspects are described in terms of particular types of mobility states (eg, stationary, low mobility, medium mobility, high mobility, etc.), other types of mobility states are also contemplated.

[0033] In some cases, a network node may change its mobility state. For example, a UE may transition from a high mobility level to a low mobility level based at least in part on, for example, a user of the UE exiting a high-speed rail transport mode and continuing to use a pedestrian transport mode. Similarly, when an IAB node's moving speed is less than a threshold, the IAB node may transition from a mobile state to a stationary state. For example, when a car is moving, the IAB node in the car may have a medium mobility level, and when the car is parked, the IAB node may have a stationary mobility level. In this case, the threshold for distinguishing between the medium mobility level and the stationary mobility level may 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), and the like.

[0034] A network node (e.g., an IAB donor or an IAB node) may transmit an SSB transmission set (e.g., an SSB burst set) to enable 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, and the like. The SSB transmission may 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 may travel into an area associated with another network node (e.g., a stationary network node). In such a case, 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 may be associated with the same PCI and may transmit SSB transmissions in the same resources, resulting in a PCI conflict and unsuccessful communication.

[0035] Some of the techniques and equipment 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 a 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 a 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 network nodes.

[0036] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and they 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 will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently of any other aspect of the present disclosure or implemented in combination. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods that are practiced using a supplement to the various aspects of the present disclosure set forth herein or other other structures, functionality, or structure and functionality. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0037] Several aspects of telecommunications systems will now be presented with reference to various devices and techniques. These devices and techniques are described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0038] It should be noted that although various aspects may be described herein using terminology generally associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applicable in communication systems based on other generations, such as 5G and later generations, including NR technology.

[0039] Figure 1 1 is a diagram illustrating a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network, a 5G or NR network, and the like. 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, Node B, gNB, 5G Node B (NB), access point, transmit reception point (TRP), and the like. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of a BS and / or a BS subsystem serving that coverage area, depending on the context in which the term is used.

[0040] 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., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example shown in FIG, 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," "Node B," "5G NB," and "cell" may be used interchangeably herein.

[0041] In some examples, the cells may not necessarily be stationary, and the geographic area of the cells may move depending on the location of the mobile BS. In some examples, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in wireless network 100 via various types of backhaul interfaces, such as direct physical connections, virtual networks, and / or the like using any suitable transport network.

[0042] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , relay station 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station may also be referred to as a relay BS, relay base station, relay, or the like.

[0043] The wireless network 100 may be a heterogeneous network including 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 a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0044] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), 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, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a 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 a wireless or wired medium.

[0045] 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 can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered customer premises 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.

[0046] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, air interface, etc. A frequency may also be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0047] like Figure 1As shown in , 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 a 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 a 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.

[0048] 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 a 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 a mobility state of an ISB 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.

[0049] Similarly, UE 120 (e.g., UE 120e) may include a communication manager 160. As described in greater detail elsewhere herein, 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 a 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, communication manager 160 may provide means for performing one or more other operations described herein.

[0050] As indicated above, Figure 1 These are provided as examples only. Other examples may differ from those regarding Figure 1 Examples described.

[0051] Figure 2 A block diagram shows a design 200 of a base station 110 (eg, a network node) and a UE 120 (eg, a network node), which may be Figure 1 One for each base station and one for each UE in . Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0052] 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 (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. Transmit processor 220 may provide means for transmitting data or control information, for example, to UE 120. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) 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., a cell-specific reference signal (CRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)). A transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on data symbols, control symbols, overhead symbols, and / or reference symbols, as applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a 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 frequency upconvert) 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 greater detail below, position coding may be utilized to generate synchronization signals to convey additional information.

[0053] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, 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. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The controller / processor 280 may provide a means for the UE 120 to determine, identify, or select, such as using determination circuitry, identification circuitry, selection circuitry, etc. The receive processor 258 may provide a means for the UE 120 to receive data or control information, such as from the BS 110. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 120 may be included in a housing.

[0054] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.) from the controller / processor 280. The transmit processor 264 may provide a means for the UE 120 to transmit data or control information, for example, to 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, if applicable, further processed by the modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At base station 110, uplink signals from UE 120 and other UEs may be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 where applicable, and further processed by receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide means for BS 110 to receive data or control information, for example, from UE 120. Receive processor 238 may provide decoded data to data sink 239 and decoded control information to controller / processor 240. Controller / processor 240 may provide means for, for example, determining, selecting, identifying, or detecting. Base station 110 may include communication unit 244.

[0055] 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) of the base station 110 may perform one or more techniques associated with selecting SSB resources based on 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) may perform or direct e.g. Figure 5 The process of 500 Figure 6 The process of 600 Figure 7 The operations of process 700, and / or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. Scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0056] 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 a mobility state of an IAB node; means for receiving (e.g., using the antenna 252, the DEMOD 254, the MIMO detector 256, the receive processor 258, the controller / processor 280, etc.) the one or more SSBs from the IAB node in the one or more resources; and the like.

Additionally or alternatively, such means may include, in conjunction with Figure 2 One or more components of UE 120 are described.

[0057] 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 a mobility state of the base station 110; 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.) 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 a mobility state of the IAB node; means for receiving (e.g., using the antenna 234, the DEMOD 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, etc.) the one or more SSBs from the IAB node in the one or more resources; etc. 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 communications manager 150. In some aspects, such means may include a communication manager 150 in conjunction with Figure 2 One or more components of base station 110 are described.

[0058] In some aspects, the base station 110 (e.g., a network node, an IAB donor, etc.) may include: means for selecting (e.g., using the controller / processor 240, the memory 242, etc.) one or more resources for the IAB node to transmit one or more SSBs, the one or more resources being associated with a 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 to enable the IAB node to 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 the 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 the like. 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 communications manager 140. In some aspects, such means may include in conjunction with Figure 2 One or more components of base station 110 are described.

[0059] As indicated above, Figure 2 These are provided as examples only. Other examples may differ from those regarding Figure 2 Examples described.

[0060] Figure 3A and 3B 3 is a diagram illustrating an example network topology 300 for a network in accordance with various aspects of the present disclosure. Self-backhauling or IAB can be deployed to use a common set of resources for access traffic and backhaul traffic. For example, a first wireless node (e.g., BS 110a, BS 110d, etc.) can communicate backhaul traffic (e.g., SSB) with a second wireless node and can communicate access traffic (e.g., SSB) with a third wireless node. Although some aspects described herein are described in terms of an IAB deployment, some aspects described herein can be used in conjunction with other types of multi-hop networks.

[0061] like Figure 3AAs shown in , example 300 may include multiple wireless nodes 302 (e.g., BSs) and multiple 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 a core network via a backhaul link 306 (e.g., a fiber connection, a wireless backhaul connection, a combination thereof, etc.). Wireless nodes 302 and 304 may communicate with each other using a link set 308 (e.g., a millimeter wave (mmWave) link set; an air interface such as 3G, 4G, 5G; any future wireless network (e.g., a 6G wireless network); etc.). Wireless node 302 (which may be a network node) may be associated with different mobility states (e.g., a stationary mobility state, a mobile mobility state (e.g., a high mobility level, a low mobility level, etc.), etc.).

[0062] like Figure 3A As further shown in FIG, one or more 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 a 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).

[0063] like Figure 3BAs shown in FIG, wireless nodes 302 and wireless nodes 304 may be arranged in a hierarchical topology to enable management of network resources. Each link 308 may be associated with a primary link endpoint (primary LEP, which may also be referred to as a serving LEP, a controlling / controller LEP, a primary LEP, a primary LEP, a managing LEP, a managing LEP, etc.) and a secondary link endpoint (secondary LEP, which may also be referred to as a served LEP, a controlled / controlled LEP, a subordinate LEP, a secondary LEP, a managed LEP, a managed LEP, etc.), which may define a hierarchy between wireless nodes 302 or 304. For example, wireless node 302-6 (e.g., which may be a CU (such as BS 110a)) may communicate with wireless node 302-7 (e.g., which may be a DU (such as BS 110d), which is a child or subordinate node of wireless node 302-6) via link 308-1 (which may be a parent link of wireless node 302-7). In this scenario, the wireless node 302-6 may provide configuration information, such as a communication configuration, rules for determining the communication configuration, and the like. Additionally or alternatively, the wireless node 302-6 may provide information about the mobility state of a child node of the wireless node 302-7 to the wireless node 302-7 (e.g., based at least in part on mobility information received from the core network). Similarly, the wireless node 302-7 may communicate with the wireless node 304-7 (e.g., a UE (such as UE 120e), which may be a child node or subordinate node of the wireless node 302-7) via the link 308-2 (which may be a child link of the wireless node 302-7). In this scenario, the wireless node 302-6 may schedule the wireless node 302-7, which may schedule the wireless node 304-7 based at least in part on the hierarchy defined herein.

[0064] As indicated above, Figure 3A and 3B are provided as examples. Other examples are possible and may differ from the examples described herein. Figure 3A and 3B Examples described.

[0065] Figure 4 is a diagram illustrating an example 400 of selecting SSB resources according to mobility state according to various aspects of the present disclosure. Figure 4 As shown in , example 400 may include BS 110a (e.g., CU), BS 110d (e.g., DU), and UE 120e. In some aspects, BS 110a may be an IAB donor and BS 110d may be an IAB node. In some aspects, the actions described herein as performed by UE 120e may be performed by BS 110d (e.g., a mobile-terminating component of an IAB node).

[0066] like Figure 410 and indicated 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 the speed, location, etc. of BS 110d to enable BS 110a to identify the mobility state of BS 110d. In some aspects, BS 110a may be configured with information identifying the mobility state of BS 110d.

[0067] 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, and the like. 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 less than a first threshold and greater than zero, the medium-speed mobility state may be associated with a speed between a first threshold and a second threshold, and the high-speed mobility state may be associated with a speed greater than a second threshold.

[0068] In some aspects, the mobility state of BS 110d may be an initial mobility state of BS 110d. Alternatively, the mobility state of BS 110d may be a 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.

[0069] As indicated by reference numeral 420, BS 110a may select one or more resources for BS 110d (e.g., one or more resources in which BS 110d is to transmit an SSB) based on the mobility state of BS 110d. For example, BS 110a may select one or more resources for BS 110d based at least in part on an indication of the mobility state provided by BS 110d. BS 110a may select resources for BS 110d that do not conflict with resources selected for another BS having a different mobility state than BS 110d (e.g., another BS 110d).

[0070] 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 the SSB) based on the mobility state of BS 110d. In this case, BS 110d (e.g., an operations, administration, and maintenance (OAM) component of BS 110d) may select resources based on criteria defined for the mobility state of BS 110d to avoid selecting resources that conflict with resources selected by another BS (e.g., another BS 110d) having a different mobility state than BS 110d.

[0071] In some aspects, one of BS 110a or BS 110d may be selected to select resources based at least in part on the type of SSB to be transmitted in the selected resources. For example, resources to be used by BS 110d for transmitting SSBs related to neighbor measurements or peer discovery (collectively referred to herein as radio resource management (RRM) SSBs) may be selected by BS 110a. As another example, resources to be used by BS 110d for transmitting cell-defined SSBs (CD-SSBs) may be selected by BS 110d.

[0072] In some aspects, the selected resource 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 resource may be associated with the stationary mobility state. As another example, if BS 110d has a mobile mobility state, the selected resource may be associated with a mobile mobility state. In some aspects, the selected resource may be associated with the type of mobile mobility state. For example, the selected resource may be associated with a low mobility state, a medium mobility state, a high mobility state, and so on.

[0073] In some aspects, the resources selected for the stationary mobility state may be in a different synchronization (sync) grid than 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 to transmit a CD-SSB may be in different synchronization grids depending on the mobility state of BS 110d. In some aspects, a first synchronization grid may be assigned (e.g., dedicated) to the stationary mobility state, and a second synchronization grid may be assigned (e.g., dedicated) to the mobile mobility state.

[0074] In some aspects, the resources selected for the stationary mobility state may have a different periodicity and / or a different time offset than 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 to transmit a CD-SSB may be in the same synchronization grid but have different periodicities and / or time offsets depending on the mobility state of BS 110d (e.g., the first set of resources may be time domain multiplexed with the second set of resources). In some aspects, a first periodicity and / or a first time offset may be assigned to the stationary mobility state, and a second periodicity and / or a second time offset may be assigned to the mobile mobility state.

[0075] 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 than the resources selected for the mobility state. For example, a first set of resources and a second set of resources that can be used by BS 110d to transmit RRM SSBs can be associated with different SMTC windows and / or STC windows depending on the mobility state of BS 110d. In some aspects, a first SMTC window and / or a first STC window can be assigned to the stationary mobility state, and a second SMTC window and / or a second STC window can be assigned to the mobile mobility state.

[0076] In some aspects, the SMTC window and / or STC window associated with the stationary mobility state and the SMTC window and / or STC window associated with the mobile mobility state can be orthogonal in time and / or orthogonal in frequency. In some aspects, the SMTC of the SMTC window and / or the STC of the STC window associated with the stationary mobility state can be different from the SMTC of the SMTC window and / or the STC of the STC window associated with the mobile mobility state (e.g., the SMTCs can overlap but identify different time and / or frequency window positions, different window durations, etc.). For example, the SMTC of the SMTC window and / or the STC of the STC window associated with the stationary mobility state can identify a PCI list and / or periodicity that is different from the PCI list and / or periodicity identified by the SMTC of the SMTC window and / or the STC of the STC window associated with the mobile mobility state.

[0077] As shown by reference numeral 430, BS 110a may provide an indication of the selected resource to BS 110d. The 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, the indication may provide notification of the selected resource to BS 110a (e.g., so that BS 110a can avoid selecting the same resource for another BS with a different mobility state). Additionally or alternatively, the 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 a 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.

[0078] As indicated by reference numeral 440, BS 110d may transmit SSBs in the selected resources and UE 120e may receive these SSBs in the selected resources. In some aspects, SSBs may be associated with cell access, cell selection, cell reselection, etc., such as CD-SSBs. For example, BS 110d may transmit CD-SSBs 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 the synchronization raster. That is, BS 110d may transmit CD-SSBs in the selected resources that correspond to the synchronization raster associated with the mobility state of BS 110d. As another example, BS 110d may transmit CD-SSBs 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 the periodicity and / or time offset. That is, BS 110d may transmit CD-SSBs in selected resources that correspond to the periodicity and / or time offset associated with the mobility state of BS 110d.

[0079] In some aspects, an SSB may be associated with neighbor search, peer discovery, neighbor measurement, etc., such as an RRM SSB. For example, BS 110d may transmit an RRM SSB in an STC window associated with the mobility state of BS 110d. That is, BS 110d may transmit the RRM SSB in selected resources corresponding to the STC window associated with the mobility state of BS 110d. In addition, UE 120e may receive the 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 to transmit the SSB).

[0080] In this manner, PCI conflicts can be avoided when a mobile network node (e.g., BS 110d) and a stationary network node are in the same area and use the same PCI. Furthermore, using different resources for the stationary mobility state and the mobile mobility state (e.g., partitioning the SSB space based at least in part on the mobility state) allows the mobile network node and the stationary network node to be configured differently (e.g., for different configurations of beam sweep periodicity, beam width, etc.) while avoiding interference. Furthermore, using different resources (e.g., STC windows and / or SMTC windows) 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 that is updated based on the movement of the mobile network node.

[0081] As indicated by reference numeral 450, UE 120e may identify the mobility state of BS 110d based at least in part on the resources used by BS 110d to transmit 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 based at least in part on a 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 based at least in part on a 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 based at least in part on an SMTC window associated with the resources in which UE 120e receives the SSB.

[0082] In some aspects, the UE 120e may be configured with information that enables the UE 120e to identify a particular mobility state associated with a particular synchronization raster, periodicity, time offset, SMTC window, etc. For example, the information may indicate that a stationary mobility state is associated with a first time offset and a mobile mobility state is associated with a second time offset.

[0083] In some aspects, UE 120e may receive SSBs from a BS in a particular mobility state. For example, UE 120e may determine to receive SSBs from a BS in a stationary mobility state (e.g., to communicate via the stationary BS) and may monitor resources associated with the stationary mobility state for SSBs. As another example, UE 120e may determine to receive SSBs from a BS in a mobile mobility state and may monitor resources associated with the mobile mobility state for SSBs.

[0084] In some aspects, UE 120e may perform measurements on received SSBs 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 on the received SSBs. For example, UE 120e may transmit a measurement report to BS 110d that identifies one or more measurements on the SSBs (e.g., a reference signal received power (RSRP) measurement, a reference signal received quality (RSRQ) measurement, a signal-to-noise ratio (SNR) measurement, a signal-to-interference-plus-noise ratio (SINR) measurement, etc.). In some aspects, UE 120e may be configured with different measurement configurations for a stationary mobility state and a mobile mobility state. For example, if BS 110d has a mobile mobility state, the measurement configuration may indicate that UE 120e is to report measurements more frequently, and if BS 110d has a stationary mobility state, the measurement configuration may indicate that UE 120e is to report measurements less frequently.

[0085] Figure 5 1 is a diagram illustrating an example process 500, for example, 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, equipment 800, equipment 900, equipment 1000, etc.) performs operations associated with selecting SSB resources based on mobility state.

[0086] like Figure 5As shown in , in some aspects, process 500 may include identifying one or more resources for receiving one or more SSBs, the one or more resources associated with a mobility state of an IAB node (block 510). For example, the 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 associated with a mobility state of an IAB node, as described above.

[0087] In some aspects, process 500 may include identifying a mobility state of the IAB node based at least in part on the one or more resources (block 512). For example, the network node (e.g., using controller / processor 280, memory 282, identifying / selecting component 808, etc.) may identify the mobility state of the IAB node based at least in part on the one or more resources, as described above.

[0088] like Figure 5 As further shown in FIG5 , 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, the 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.

[0089] like Figure 5 As further shown in FIG5 , in some aspects, process 500 may include performing measurements of the one or more SSBs (block 530).

[0090] Process 500 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

In an eighth aspect, 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, the first PCI list or the first periodicity being different from a second PCI list or a second periodicity identified by the SMTC of the second SMTC window.

[0096] although Figure 5 Example blocks of process 500 are shown, but in some aspects, process 500 may include Figure 55. In some embodiments, the process 500 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in FIG. Additionally or alternatively, two or more blocks of process 500 may be executed in parallel.

[0097] Figure 6 6 is a diagram illustrating an example process 600, for example, performed 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, equipment 800, equipment 900, equipment 1000, etc.) performs operations associated with selecting SSB resources based on mobility state.

[0098] like Figure 6 As 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 associated with a mobility state of an IAB node (block 610). For example, the 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 associated with a mobility state of an IAB node, as described above.

[0099] In some aspects, process 600 may include selecting the one or more resources (block 612). For example, the 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, the 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.

[0100] like Figure 6 As further shown in FIG. 6 , in some aspects, process 600 may include transmitting the one or more SSBs in the one or more resources (block 620). For example, the network node (e.g., using transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, controller / processor 240, transmission component 804, etc.) may transmit the one or more SSBs in the one or more resources, as described above.

[0101] Process 600 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] In a sixth aspect, 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.
