Technical Field

[0003] Generally speaking, the following relates to wireless communications, and more specifically, the following relates to resource configuration management in wireless communications. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting, etc. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multi - access systems include fourth - generation (4G) systems (e.g., Long - Term Evolution (LTE) systems, enhanced LTE (LTE - A) systems, or LTE - A Pro systems) and fifth - generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT - S - OFDM). A wireless multi - access communication system may include multiple base stations or network access nodes, each of which simultaneously supports communication for multiple communication devices (which may also be referred to as User Equipment (UE)).

[0005] In some wireless communication systems (e.g., 5G New Radio (NR) systems), the infrastructure and spectrum resources for NR access can additionally support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an integrated access and backhaul (IAB) network architecture. One or more base stations can include a central unit (CU) and a distributed unit (DU), and can be referred to as donor base stations. One or more DUs associated with a donor base station can be partially controlled by the CU associated with the donor base station. One or more donor base stations (e.g., IAB donors) can communicate with one or more additional base stations (e.g., IAB nodes) via supported access and backhaul links. An IAB node can support mobile terminal (MT) functions controlled and / or scheduled by the DU of a coupled IAB donor and additional entities (e.g., IAB nodes, UEs, etc.) within the relay chain or configuration with respect to the access network (e.g., downstream). The radio resources for the backhaul link and for the access link can be configured by the CU, and one or more IAB nodes provide the access link and the backhaul link according to the resource configuration. Efficient techniques for allocating radio resources in such networks may be desirable. Summary of the Invention

[0006] The described techniques relate to improved methods, systems, devices, and apparatuses for supporting resource configuration management in wireless communications. According to various aspects, wireless resource configurations for a multi-hop wireless network (e.g., an integrated access and backhaul (IAB) network) can be configured and selected based on current network conditions to provide efficient updates to the resource configuration. In some cases, a central entity (e.g., the central unit (CU) of an IAB network) can configure one or more other nodes of the network with multiple different wireless resource configurations for backhaul communication between the other nodes. In some cases, a first node (e.g., an IAB relay node, a parent node, a child node, etc.) can receive multiple different wireless resource configurations, identify the radio resources associated with a first resource configuration (e.g., time resource, frequency resource, spatial resource, etc.) allocated for backhaul communication, and communicate with a second node (e.g., an IAB relay node, a parent node, a child node, etc.) using the allocated resources. In the case where the first node determines that a different wireless resource configuration should be used for communication with the second node, the first node can select a second resource configuration from the multiple different wireless resource configurations for further communication with the second node. In some cases, the first node can provide an indication of the second resource configuration to the second node and optionally to the central entity.

[0037] In some wireless communication systems (e.g., 5G New Radio (NR) systems), the infrastructure and spectrum resources for NR access can support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an integrated access and backhaul (IAB) network architecture. One or more base stations can include a central unit (CU) and a distributed unit (DU), and can be referred to as a donor base station (e.g., or IAB donor). One or more DUs associated with the donor base station can be partially controlled by the CU associated with the donor base station. The base station CU can be a component of a database, a data center, a core network, or a network cloud. Network nodes associated with a radio access technology (RAT) can communicate with the donor base station CU via a backhaul link (e.g., wired backhaul or wireless backhaul). One or more donor base stations (e.g., IAB donors) can communicate with one or more additional base stations (e.g., IAB nodes or relay nodes) and user equipment (UE). An IAB node can support MT functions controlled and scheduled by an IAB donor and / or a parent IAB node with respect to a mobile terminal (MT), and DU operability with respect to a relay chain or additional entities (e.g., IAB nodes, UEs, etc.) within a configuration of the access network (e.g., downstream). For example, an IAB network architecture can include a chain of connected wireless devices via link resources supporting NR access and backhaul capabilities (e.g., wired backhaul or wireless backhaul) (e.g., starting from a donor base station and ending with a user equipment (UE), with any number of IAB relay nodes in between). Although various examples provided herein illustrate and discuss IAB deployments, it should be understood that the techniques provided herein can be applied to any multi-hop wireless network where a central entity can configure other wireless nodes (e.g., parent nodes, child nodes, etc.) for relay or multi-hop wireless communication.

[0038] A relay node can refer to an intermediate node in a relay (e.g., IAB relay) chain. For example, a relay node can relay communication between a parent node (e.g., an IAB donor, or an upstream or higher IAB node on the relay chain) and a child node (e.g., a downstream or lower IAB node on the relay chain). In some cases, a relay node can refer to the DU or access node function unit (AN-F) of an intermediate IAB node. A child node can refer to an IAB node (e.g., the CU / MT of an IAB node) or a UE (e.g., the DU / ANF of an IAB node or IAB donor) that is a child of another IAB node (e.g., such as a relay node) or an IAB donor. A parent node communicating with a relay node can refer to an upstream IAB node or an IAB donor (e.g., the DU / ANF of an IAB node or IAB donor).

[0039] The IAB network architecture can support increased backhaul density within the relay chain to compensate for the mobile capacity density in one or more serving cells corresponding to base stations supported on the network (e.g., IAB donors, IAB nodes). For example, several IAB nodes can each communicate with one or more UEs, and the IAB nodes are controlled and scheduled by one or more DUs via a backhaul link. In some cases, a single backhaul connection can support multiple RATs and assist in increasing the spectrum gain.

[0040] Thus, such a multi-hop network can use wireless resources (time / frequency resources, spatial resources, etc.) in a shared manner between the access link and the backhaul link. In some cases, wireless nodes can communicate the resource configuration for the resources used for the access link and the backhaul link according to a definition. Such resource configurations can be managed by a central entity in the wireless network. In some systems, the central entity can semi-statically configure other wireless nodes of the network with the resource configuration. For example, the CU in an NR IAB network can provide the resource configuration to the IAB nodes via radio resource control (RRC) signaling. The resource configuration can include different types of resources that provide some flexibility to the configured nodes, such as by providing some resources (e.g., soft resources) that can be managed locally and dynamically (e.g., if the parent node does not need its allocated (e.g., hard) resources, they can be lent to its child nodes). However, in some cases, the network conditions may change such that even though the soft / hard resources have some flexibility, the resource configuration is relatively inefficient for the connection. In addition, by exchanging RRC signaling to provide a new configuration, updating the resource configuration is relatively slow and generates a relatively high resource overhead in such cases.

[0041] The various techniques provided herein provide enhanced efficiency and reduced overhead, which can allow for updating resource configurations based on network conditions. In some cases, a central entity can configure a set of available resource configurations at one or more nodes of a multi-hop wireless network. Then, a node can select a particular resource configuration for further communication. In some cases, the central entity can configure an initial or default resource allocation, which can be updated as needed when network conditions change (e.g., based on changed traffic characteristics, changed channel conditions, etc.) to another resource configuration in the set of available resource configurations. In some cases, the central entity can provide an explicit indication to switch resource configurations. In other cases, a node can update the resource configuration without an explicit indication from the central entity and can optionally notify the central entity of the updated configuration. In some cases, a wireless node can determine a new instance of the resource configuration to be used based on an indication from one or more parent nodes (e.g., in downlink control information (DCI), medium access control (MAC) control element (CE), or any combination thereof), from one or more child nodes (e.g., in uplink control information (UCI), MAC-CE, or any combination thereof), based on some preconfigured criteria, or any combination thereof. When changing an instance of the resource configuration at a wireless node, a notification can be provided to one or more of a parent node, a child node, the central entity, or any combination thereof.

[0042] Accordingly, the techniques described herein provide enhanced efficiency and reliability in a wireless network by selecting and updating resource configurations relatively quickly and with relatively low signaling overhead. Such techniques can provide enhanced network capacity by using wireless resources in an efficient manner and can also reduce network overhead by selecting preconfigured resource configurations with relatively little or no overhead signaling that would otherwise be used to provide updated configurations (e.g., RRC signaling to provide a new resource configuration). Additionally, such techniques can provide enhanced network reliability by selecting resource configurations that can adapt to changing network conditions in an efficient and rapid manner.

[0043] Aspects of the present disclosure are first described in an exemplary context of a wireless communication system. Further, aspects of the present disclosure are illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts related to resource configuration management in wireless communication.

[0044] Figure 1FIG. 0 illustrates an example of a wireless communication system 100 that supports resource configuration management in wireless communication in accordance with aspects of the present disclosure. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an evolved LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some cases, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, or communications with low-cost and low-complexity devices.

[0045] The base station 105 may communicate wirelessly with the UE 115 via one or more base station antennas. The base station 105 described herein may include or may be referred to by those skilled in the art as a base station transceiver, a radio base station, an access point, a radio transceiver, a Node B, an eNodeB (eNB), a next-generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a home Node B, a home evolved Node B, or some other suitable term. The wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). The UE 115 described herein is capable of communicating with various types of base stations 105 and network devices (including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.).

[0046] Each base station 105 may be associated with a particular geographic coverage area 110 in which communication with respective UEs 115 is supported. Each base station 105 may provide communication coverage for the corresponding geographic coverage area 110 via a communication link 125, and the communication link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communication link 125 shown in the wireless communication system 100 may include: an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. The downlink transmission may also be referred to as a forward link transmission, and the uplink transmission may also be referred to as a reverse link transmission.

[0047] The geographical coverage area 110 for a base station 105 can be divided into sectors, which form part of the geographical coverage area 110, and each sector can be associated with a cell. For example, each base station 105 can provide communication coverage for a macro cell, a small cell, a hotspot, or other types of cells, or various combinations thereof. In some examples, the base station 105 can be movable and, thus, provide communication coverage for a movable geographical coverage area 110. In some examples, different geographical coverage areas 110 associated with different technologies can overlap, and the overlapping geographical coverage areas 110 associated with different technologies can be supported by the same base station 105 or different base stations 105. The wireless communication system 100 can include, for example, a heterogeneous LTE / LTE-A / LTE-A Pro or NR network, where different types of base stations 105 provide coverage for respective geographical coverage areas 110.

[0048] The term "cell" refers to a logical communication entity for communication with a base station 105 (e.g., on a carrier), and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID)) used to distinguish adjacent cells operating via the same or different carriers. In some examples, a carrier can support multiple cells, and different cells can be configured according to different protocol types (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), or other protocol types), and the different protocol types can provide access for different types of devices. In some cases, the term "cell" can refer to a part (e.g., a sector) of the geographical coverage area 110 on which the logical entity operates.

[0049] UEs 115 can be scattered throughout the wireless communication system 100, and each UE 115 can be stationary or movable. A UE 115 can also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a user equipment, or some other suitable term, where "device" can also be referred to as a unit, a station, a terminal, or a client. A UE 115 can also be a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 can also refer to a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, etc., which can be implemented in various articles such as appliances, vehicles, meters, etc.

[0050] Some UEs 115 (e.g., MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with the base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices integrated with sensors or meters to measure or capture information and relay that information to a central server or application that can utilize the information or present the information to a human interacting with the program or application. Some UEs 115 can be designed to collect information or implement automated behavior of machines. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, device monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing.

[0051] Some UEs 115 can be configured to operate in power-saving modes, e.g., half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception rather than simultaneous transmission and reception). In some examples, half-duplex communication can be performed at a reduced peak rate. Other power-saving techniques for UEs 115 include entering a power-saving "deep sleep" mode when not participating in active communication or operating on a limited bandwidth (e.g., according to narrowband communication). In some cases, UEs 115 can be designed to support critical functions (e.g., mission-critical functions), and the wireless communication system 100 can be configured to provide ultra-reliable communication for these functions.

[0052] In some cases, UEs 115 are also capable of communicating directly with other UEs 115 (e.g., using peer-to-peer (P2P) or device-to-device (D2D) protocols). One or more UEs 115 in a group of UEs 115 utilizing D2D communication can be within the geographical coverage area 110 of the base station 105. Other UEs 115 in such a group can be outside the geographical coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some cases, multiple groups of UEs 115 communicating via D2D communication can utilize a one-to-many (1:M) system, where each UE 115 transmits to each other UE 115 in the group. In some cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0053] Base station 105 can communicate with the core network 130 and with each other. For example, base station 105 can interface with the core network 130 via a backhaul link 132 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via the core network 130) on a backhaul link 134 (e.g., via X2, Xn, or other interfaces).

[0054] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC), which can include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME can manage non-access stratum (e.g., control plane) functions, such as mobility, authentication, and bearer management for a UE 115 served by a base station 105 associated with the EPC. User IP packets can be transmitted through the S-GW, which itself can be connected to the P-GW. The P-GW can provide IP address allocation and other functions. The P-GW can be connected to network operator IP services. The operator IP services can include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet-switched (PS) streaming services.

[0055] At least some of the network devices (e.g., base station 105) can include subcomponents such as access network entities, which can be examples of access node controllers (ANC). Each access network entity can communicate with a UE 115 through a plurality of other access network transmission entities (which can be referred to as radio heads, intelligent radio heads, or transmit / receive points (TRP)). In some configurations, the various functions of each access network entity or base station 105 can be distributed across various network devices (e.g., radio heads and access network controllers) or consolidated into a single network device (e.g., base station 105).

[0056] The wireless communication system 100 can operate using one or more frequency bands (commonly in the range of 300 megahertz (MHz) to 300 gigahertz (GHz)). Generally, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or the decimeter band because the wavelength range is from approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features. However, the waves can be sufficient to penetrate structures for a macro cell to serve a UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0057] The wireless communication system 100 can also operate in the super-high frequency (SHF) region using frequency bands from 3 GHz to 30 GHz (also referred to as the centimeter band). The SHF region includes bands such as the 5 GHz industrial, scientific, and medical (ISM) band, which can be opportunistically used by devices that can tolerate interference from other users.

[0058] The wireless communication system 100 can also operate in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as the millimeter band). In some examples, the wireless communication system 100 can support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices can be even smaller and more closely spaced compared to UHF antennas. In some cases, this can facilitate the use of antenna arrays within the UE 115. However, compared to SHF or UHF transmissions, EHF transmissions can suffer even greater atmospheric attenuation and shorter distances. The techniques disclosed herein can be employed across transmissions using one or more different frequency regions, and the specified use of frequency bands across these frequency regions can vary according to the country or regulatory body.

[0059] In some cases, the wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ Licensed-Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technologies, or NR technologies in an unlicensed frequency band (e.g., the 5 GHz ISM band). When operating in an unlicensed radio frequency spectrum band, wireless devices (e.g., the base station 105 and the UE 115) may employ a Listen-Before-Talk (LBT) procedure before transmitting data to ensure that the frequency channel is idle. In some cases, the operation in the unlicensed frequency band may be based on a carrier aggregation configuration that combines component carriers operating in a licensed frequency band (e.g., LAA). The operation in the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in the unlicensed spectrum may be based on Frequency Division Duplexing (FDD), Time Division Duplexing (TDD), or a combination of both.

[0060] In some examples, the base station 105 or the UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, Multiple-Input Multiple-Output (MIMO) communication, or beamforming. For example, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., the base station 105) and a receiving device (e.g., the UE 115), where the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communication may utilize multipath signal propagation to improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers (which may be referred to as spatial multiplexing). For example, the transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Similarly, the receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams. Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques include Single-User MIMO (SU-MIMO) (where multiple spatial layers are transmitted to the same receiving device) and Multi-User MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).

[0061] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., base station 105 or UE 115) to form or direct an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via the antenna elements of an antenna array such that signals propagating in a particular orientation relative to the antenna array experience constructive interference while other signals experience destructive interference. Adjusting the signals transmitted via the antenna elements can include the transmitting device or the receiving device applying certain amplitude and phase offsets to the signals carried by each of the antenna elements associated with the device. The adjustment associated with each of the antenna elements can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0062] In some cases, the antennas of base station 105 or UE 115 can be located within one or more antenna arrays, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays can be co-located at an antenna assembly, such as an antenna tower. In some cases, the antennas or antenna arrays associated with base station 105 can be located at different geographical locations. Base station 105 can have an antenna array with multiple rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 can have one or more antenna arrays that can support various MIMO or beamforming operations.

[0063] In some cases, wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, communication at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly for communication over logical channels. The medium access control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use hybrid automatic repeat request (HARQ) to provide retransmission at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration, and maintenance of an RRC connection (which supports radio bearers for user plane data) between UE 115 and base station 105 or core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0064] In some cases, the UE 115 and the base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. HARQ feedback is a technique that increases the likelihood that data is correctly received over the communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., signal-to-noise conditions). In some cases, a wireless device may support same-slot HARQ feedback, where the device may provide HARQ feedback for data received in previous symbols in a particular slot within that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0065] Time intervals in LTE or NR can be expressed as multiples of a basic time unit, which may refer to, for example, a sampling period of T s = 1 / 30,720,000 seconds. The time intervals of communication resources can be organized according to radio frames, each having a duration of 10 milliseconds (ms), where the frame period can be expressed as T f = 307,200T s . A radio frame can be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame can include 10 subframes numbered from 0 to 9, and each subframe can have a duration of 1 ms. A subframe can also be divided into 2 time slots, each having a duration of 0.5 ms, and each time slot can contain 6 or 7 modulation symbol periods (e.g., depending on the length of the cyclic prefix added in front of each symbol period). Excluding the cyclic prefix, each symbol period can contain 2048 sampling periods. In some cases, a subframe can be the smallest scheduling unit of the wireless communication system 100 and can be referred to as a transmission time interval (TTI). In other cases, the smallest scheduling unit of the wireless communication system 100 can be shorter than a subframe or can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs) or in a selected component carrier using sTTIs).

[0066] In some wireless communication systems, a time slot can be further divided into multiple mini-slots each containing one or more symbols. In some instances, the symbols or mini-slots of a mini-slot can be the smallest scheduling unit. The duration of each symbol can vary depending on, for example, the subcarrier spacing or the operating frequency band. Additionally, some wireless communication systems can implement time slot aggregation, where multiple time slots or mini-slots are aggregated together and used for communication between the UE 115 and the base station 105.

[0067] The term "carrier" refers to a collection of radio frequency spectrum resources having a defined physical layer structure for supporting communication on communication link 125. For example, the carrier of communication link 125 may include a portion of a radio frequency spectrum band that operates according to the physical layer channels for a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. A carrier may be associated with a predefined frequency channel (e.g., evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and may be placed according to a channel grid for discovery by UE 115. A carrier may be downlink or uplink (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode). In some examples, the signal waveform transmitted on a carrier may be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)).

[0068] For different radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR), the organizational structure of a carrier may be different. For example, communication on a carrier may be organized according to a TTI or a time slot, each of which may include user data and control information or signaling for supporting decoding of the user data. A carrier may also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling for coordinating the operation of the carrier. In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling for coordinating the operation of other carriers.

[0069] Physical channels may be multiplexed on a carrier according to various techniques. For example, time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques may be used to multiplex physical control channels and physical data channels on a downlink carrier. In some examples, the control information transmitted in a physical control channel may be distributed in a cascaded manner between different control regions (e.g., between a common control region or a common search space and one or more UE-specific control regions or UE-specific search spaces).

[0070] A carrier can be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth can be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of predetermined bandwidths of a carrier for a specific radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). In some examples, each served UE 115 can be configured to operate on a portion or all of the carrier bandwidth. In other examples, some UEs 115 can be configured to operate using a narrowband protocol type associated with a predefined portion or range within the carrier (e.g., a set of subcarriers or RBs) (e.g., "in-band" deployment of the narrowband protocol type).

[0071] In a system employing MCM technology, a resource element can consist of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme). Thus, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate can be for the UE 115. In an MIMO system, the wireless communication resources can refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers), and the use of multiple spatial layers can further increase the data rate for communication with the UE 115.

[0072] Devices of the wireless communication system 100 (e.g., the base station 105 or the UE 115) can have a hardware configuration that supports communication on a specific carrier bandwidth, or can be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 can include the base station 105 and / or the UE 115 that support simultaneous communication via carriers associated with more than one different carrier bandwidth.

[0073] The wireless communication system 100 can support communication with the UE 115 on multiple cells or carriers (a feature that can be referred to as carrier aggregation or multi-carrier operation). According to the carrier aggregation configuration, the UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used with both FDD component carriers and TDD component carriers.

[0074] In some cases, the wireless communication system 100 may support wireless backhaul communication, and one or more base stations 105 may include a CU and a DU, where one or more DUs associated with the base station 105 may be partially controlled by the CU associated with the base station 105. The base station CU may be a database, a data center, or a component of the core network 130 (e.g., 5G NR core network (5GC)). The base station CU may communicate with the donor base station 105 via a backhaul link 132 (e.g., wired backhaul or wireless backhaul). As another example, in an IAB network, the base station CU (e.g., donor base station 105-a) may communicate with the core network 130 (e.g., NGC) via a backhaul link 132 (e.g., wired backhaul or wireless backhaul). For example, in an IAB network, the donor base station 105 may be referred to as an IAB donor and may communicate with one or more IAB nodes (e.g., other base stations 105) operating as base station DUs with respect to the IAB donor and one or more UEs. For example, an IAB network may include a chain of wireless devices (e.g., starting from the donor base station 105 (a RAN node that terminates the interface with the core network) and ending with the UE 115, with any number of IAB nodes in between). An IAB node (e.g., a relay node) may support MT functions (which may also be referred to as UE functional units (UE-F)) controlled and scheduled by the IAB donor or another IAB node, as well as DU functions (which may also be referred to as access node functional units (AN-F)) with respect to its parent node and additional entities (e.g., IAB nodes, UEs, etc.) within the relay chain or configuration with respect to the access network (e.g., downstream). These relay mechanisms may forward traffic to additional entities, extend the wireless access range of one or more base stations, enhance the density of the backhaul capabilities within the serving cell 110, and so on.

[0075] In some cases, the wireless resource configuration for a multi-hop wireless network (e.g., an integrated access and backhaul (IAB) network) can be configured and selected based on the current network conditions to provide an efficient update of the resource configuration. In some cases, the CU can configure one or more other nodes of the network with multiple different wireless resource configurations for backhaul communication between the other nodes. In some cases, a first node (e.g., an IAB relay node, a parent node, a child node, etc. at base station 105) can receive multiple different wireless resource configurations, identify the wireless resources associated with a first resource configuration (e.g., time resource, frequency resource, spatial resource, etc.) allocated for backhaul communication, and communicate with a second node (e.g., an IAB relay node, a parent node, a child node, etc. at base station 105) using the allocated resources. In the case where the first node determines that a different wireless resource configuration should be used for communication with the second node, the first node can select a second resource configuration from the multiple different wireless resource configurations for further communication with the second node. In some cases, the first node can provide an indication of the second resource configuration to the second node and optionally to the CU.

[0076] Figure 2 FIG. 4 shows an example of a multi-hop wireless communication system 200 that supports resource configuration management in wireless communication in accordance with aspects of the present disclosure. In some examples, the multi-hop wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system 200 can include base stations 205, 210, and 215 and UEs 230, 240, and 250, which can be examples of the corresponding devices described herein. In some aspects, the wireless communication system 200 can operate in the mmW radio frequency spectrum band. In some aspects, any one of the base stations 205, 210, 215 and / or UEs 230, 240, 250 can implement aspects of the described techniques in a licensed radio frequency spectrum band and / or a shared or unlicensed radio frequency spectrum band.

[0077] In some aspects, the multi-hop wireless communication system 200 can be an example of an IAB network. For example, the base stations 205, 210, and 215 can be nodes within the IAB network. Thus, the base station 205 can communicate with the base station 210 on the backhaul link 220, and vice versa (e.g., using a first wireless resource configuration). The base station 210 can communicate with the base station 215 on the backhaul link 225 (e.g., using a second resource configuration) and / or communicate with the UE 230 on the access link 235, and vice versa. The base station 215 can communicate with the UE 240 on the access link 245 and / or communicate with the UE 250 on the access link 255, and vice versa.

[0078] As described above, aspects of the present disclosure describe techniques that can support wireless communication according to one of a plurality of pre-configured resource configurations. For example, a central entity (e.g., an entity at base station 205 or in the core network) can manage resource configurations for backhaul links 220, 225 and access links 235, 245, 255. In some cases, the central entity can semi-statically configure other wireless nodes of the network (e.g., wireless nodes acting as base stations 205, 210, 215) with a plurality of available resource configurations. For example, the CU in an IAB network can provide a set of available resource configurations to an IAB node via RRC signaling as part of an initial configuration or an updated configuration of the multi-hop wireless communication system 200. Then, the wireless node can select a particular resource configuration for communication based on current network conditions.

[0079] In some cases, the central entity can configure an initial or default resource allocation, which can be updated as needed when network conditions change (e.g., based on changed traffic characteristics, changed channel conditions, etc.) to another resource configuration in the set of available resource configurations. In some cases, the central entity can provide an explicit indication to switch resource configurations. In other cases, the wireless node can update the resource configuration without an explicit indication from the central entity and can optionally notify the central entity of the updated configuration. In some cases, the wireless node can determine a new instance of the resource configuration to be used based on indications from one or more parent nodes (e.g., in DCI, MAC-CE, or any combination thereof), from one or more child nodes (e.g., in UCI, MAC-CE, or any combination thereof), based on some pre-configured criteria, or any combination thereof.

[0080] When changing an instance of the resource configuration at a wireless node, a notification can be provided to one or more of a parent node, a child node, a central entity, or any combination thereof. For example, a child node (e.g., an IAB relay node) operating at base station 210 can receive an indication from a parent node (e.g., an IAB donor node) operating at base station 205, which is used to indicate that the parent node has adopted a new instance or wireless resource configuration from a set of pre-configured resource configurations. In the case of a configuration change, the parent node can send an indication of the updated resource configuration. In some cases, the child node can map the indicated parent resource configuration to one or more instances of pre-configured wireless resources in a set of pre-configured wireless configurations located at the child node. For example, the parent node can indicate that a configuration using a certain time slot pattern (e.g., even-numbered time slots) has been selected for backhaul communication with the parent node, and can provide a mapping indicating one or more child node configurations (e.g., a configuration using odd time slots for child node communication with a downstream node such as base station 215) that are compatible with the time slot pattern. Based on the mapping, the child node can determine an instance of the pre-configured resource configuration set from a downward-selected list for use at the child node. In some cases, such a relationship or mapping can be explicitly configured or indicated to the child node (e.g., by the CU), or can be implicitly inferred by the child node based on one or more rules (e.g., looking for a matching resource configuration instance according to available / unavailable resources and / or uplink / downlink directions). In some cases, the parent node can know (e.g., based on an indication from the central entity) the child node resource configuration instance, and can select one such instance and indicate it to the child node.

[0081] In some cases, the central entity can provide an indication to another node that the resource configuration will be updated. In other cases, a wireless node (e.g., a parent node at base station 210) can adopt a new instance from a list of pre-configured resource configurations without an explicit indication. In some cases, the parent node can select an updated resource configuration based on an indication from one or more child nodes (e.g., a child node at base station 215). For example, the child node can send information to the parent node to indicate its own resource configuration (and when / if it changes its configuration) or a request to change its configuration. In response to the indication from the child node, the parent node can then change its own resources. Additionally, in some cases, the parent node can provide an indication to the child node (e.g., in response to a child node request, or an indication of its own configuration change).

[0082] In some cases, a wireless node (e.g., a parent node at base station 210) may select an updated resource configuration based on one or more criteria (e.g., one or more pre-configured criteria that may be standardized or provided by a central entity or the parent node for use in selecting or changing an instance of its resource configuration). For example, the parent node may select a resource configuration based on a transmission beam for communication. In such an example, based on a serving beam on a backhaul link with another parent node or donor node, a resource for communication with one or more child nodes may be selected. When mmW communication is employed for the backhaul link, such techniques may be used, and the backhaul link may use multiplexing techniques (e.g., spatial multiplexing, frequency multiplexing, time multiplexing, or a combination thereof), which may depend on the beams used at the parent / child nodes (e.g., when the beams require a certain level of spatial separation). In such a case, when the parent node indicates a change in the beam on the backhaul link, the child node may autonomously change its resource configuration for its associated child node link (and provide an indication of the resource configuration).

[0083] Additionally or alternatively, in cases where the resource configuration is updated based on pre-configured criteria, one or more rules for selecting or changing an instance of the resource configuration may be defined (e.g., in a network specification or a configuration provided by a central entity or the parent node). For example, the selection of the resource configuration may depend on an energy-saving mode for backhaul communication. In such a case, when the parent node or the child node changes the energy-saving mode, the upstream or downstream node may autonomously update its associated resource configuration (e.g., with or without providing an indication to the central entity). In other cases, the selection of the resource configuration may depend on the topological state of the node (e.g., hop level, number of sub-links, number of parents, etc.). Additionally or alternatively, the selection of the resource configuration may depend on the type of traffic or service supported by the node (e.g., when there is an active session for high-priority traffic such as ultra-reliable low-latency communication (URLLC) traffic, the resource configuration may be different to improve latency, reliability, or both).

[0084] When selecting an updated resource configuration, the parent node, the child node, and the central entity may communicate according to the selected resource configuration until the resource configuration can be updated again. Thus, such techniques allow for an efficient update of resource allocation based on network conditions and with relatively low signaling overhead, which can enhance overall network efficiency and reliability.

[0085] As indicated herein, in some cases, resource configuration techniques may be employed in any type of multi-hop wireless network, which may include an IAB network. Figure 3FIG. 0 shows an example of an IAB network in a wireless communication system 300 that supports resource allocation management in wireless communication in accordance with aspects of the present disclosure. In some examples, wireless communication system 300 may implement aspects of wireless communication systems 100 or 200. Wireless communication system 300 (e.g., an NR system, a mmW system, etc.) may supplement a wired backhaul connection (e.g., wired backhaul link 320) by leveraging wireless backhaul link capabilities to share infrastructure and spectrum resources for network access, thereby providing an IAB network architecture.

[0086] Wireless communication system 300 may include a core network 305 and base stations (e.g., Figure 1 and 2 base stations 105, 205, 210, 215) or supported devices that are split into one or more support entities (i.e., functions) to cooperate for communication access to increase wireless backhaul density. Aspects of the support functions of the base stations may be referred to as IAB nodes, such as IAB donor node 310 and IAB relay node 315. Wireless communication system 300 may additionally support multiple UEs 115, which may communicate on the uplink with one or more IAB donor nodes 310, IAB relay nodes 315, or a combination of these devices.

[0087] The wireless communication system 300 may include one or more IAB donor nodes 310, which may interface between a wired network and a wireless network. In some cases, the IAB donor node 310 may be referred to as an anchor node because the IAB donor node 310 anchors the wireless network to the wired connection. For example, each IAB donor node 310 may include at least one wired backhaul link 320 and one or more additional links (e.g., wireless backhaul link 325, standby wireless backhaul link 330, access link 335). The IAB donor node 310 may be split into associated base station central unit (CU) and distributed unit (DU) entities, where one or more DUs associated with the IAB donor node 310 may be partially controlled by the associated CU. The CU of the IAB donor node 310 may host layer 3 (L3) (e.g., RRC, service data adaptation protocol (SDAP), PDCP, etc.) functions and signaling. In addition, the CU of the IAB donor node 310 may communicate with the core network 305 over the wired backhaul link 320 (e.g., which may be referred to as the NG interface). The DU may host lower layer operations, such as layer 1 (L1) or layer 2 (L2) (e.g., RLC, MAC, physical layer) functions and signaling. The DU entity of the IAB donor node 310 may support serving cells within the network coverage area according to the connections associated with the wireless backhaul link 325 and the access link 335 of the IAB network. The DU of the IAB donor node 310 may control the access and backhaul links within the corresponding network coverage and may provide control and scheduling for the subsequent (i.e., sub) IAB relay nodes 315 and / or UE 115. For example, the DU may support RLC channel connections with the UE 115 (e.g., via the access link 335) or with the IAB relay node 315 (e.g., via the backhaul link, such as the primary wireless backhaul link 325 or the standby wireless backhaul link 330).

[0088] The IAB relay node 315 can be split into an associated mobile terminal (MT) and a base station DU entity, where the MT function of the IAB relay node 315 can be controlled or scheduled by a previous (i.e., parent) IAB node via a wireless backhaul link. The parent node of the IAB relay node 315 can be another (previous) IAB relay node 315 or an IAB donor node 310. The MT function can be similar to the function performed by the UE 115 in the system. The IAB relay node 315 may not be directly connected to the wired backhaul 320. Instead, the IAB relay node 315 can use a wireless backhaul link to connect to the core network 305 via other IAB nodes (e.g., any number of additional IAB relay nodes 315 and IAB donor nodes 310). The IAB relay node 315 can use the MT function to send upstream (e.g., to the core network 305) in the IAB system. In some cases, the DU of the IAB relay node 315 can be partially controlled by a signaling message from the CU entity of the associated IAB donor node 310 (e.g., sent via the F1 application protocol (AP)). The DU of the IAB relay node 315 can support the serving cell of the network coverage area. For example, the DU of the IAB relay node 315 can perform the same or similar functions as the DU of the IAB donor node 310, supporting one or more access links 335 for the UE 115, one or more wireless backhaul links for the downstream IAB relay node 315, or both.

[0089] The wireless communication system 300 may communicate within an IAB network architecture using a relay chain. For example, the UE 115 may communicate with an IAB node, and the IAB node may relay data directly or via one or more IAB relay nodes 315 to the base station CU or the core network 305. Each IAB relay node 315 may include a primary wireless backhaul link 325 for relaying data upstream or receiving information from the base station CU or the core network 305. In some cases, the IAB relay node 315 may additionally include one or more secondary wireless backhaul links 330 (e.g., for redundant connection or improved robustness). If the primary wireless backhaul link 325 fails (e.g., due to interference, failure at the connected IAB node, movement of the IAB node, maintenance at the IAB node, etc.), the IAB relay node 315 may utilize the secondary wireless backhaul link 330 to perform backhaul communication within the IAB network. The first (e.g., primary) wireless backhaul link 325 may be associated with a coverage area, and the MT function may be controlled or scheduled by the first parent node. One or more secondary backhaul links (e.g., secondary wireless backhaul links 330) may be associated with non-collocated coverage areas and be controlled and / or scheduled by one or more parent nodes. Each of the primary backhaul connection and the one or more secondary connections may support spectral capabilities to provide network communication via one or more RATs. One or more IAB nodes may also support a base station DU entity and may support multiple backhaul and access links within the relay chain. The DU entity may control or schedule downstream IAB relay nodes 315 and UE 115 within the IAB network (e.g., downstream in the IAB network) via the configured backhaul and access links. That is, the IAB relay node 315 may act as a repeater between the IAB donor node 310 and one or more downstream devices (e.g., other IAB relay nodes 315, UE 115, etc.) in both communication directions based on the established backhaul and access connections.

[0090] In some cases, the wireless communication system 300 may support preconfigured wireless resource configurations and their dynamic selection according to the techniques discussed herein. In some cases, the CU may configure one or more other nodes of the network with multiple different wireless resource configurations for backhaul communication between the other nodes. In some cases, the CU may configure each node (e.g., donor node 310, relay node 315) with a different wireless resource configuration (which may be the same set of configurations for each node or may be different sets of configurations for different nodes). Each node may identify the wireless resources associated with the first resource configuration (e.g., time resource, frequency resource, spatial resource, etc.) allocated for backhaul communication and communicate with a second node using the allocated resources. In the case where a node determines that a different wireless resource configuration should be used for communication, it may do so according to, for example, a reference Figure 1 and2 The techniques discussed to select a second resource configuration from multiple different wireless resource configurations for further communication.

[0091] Figure 4 An example of a process flow 400 that supports resource configuration management in wireless communication in accordance with aspects of the present disclosure is shown. In some examples, process flow 400 may implement aspects of wireless communication systems 100, 200, or 300. Process flow 400 may include one or more nodes, which may include a central entity 405, a first node 410, and a second node 415, which may be examples of support functions within a base station of a multi-hop wireless network architecture, as described with reference to Figures 1 to 3 described. In the following description of process flow 400, operations between nodes 405, 410, 415 may be sent in a different order than the exemplary order shown, or operations performed by the nodes may be executed in a different order or at different times. In some cases, certain operations may be omitted from process flow 400, or other operations may be added to process flow 400.

[0092] In this example, at 420, a central entity 405 (e.g., a CU of an IAB network) may configure a first node 410 (e.g., a parent node or a donor node of an IAB network) and a second node 415 (e.g., a child node of an IAB network) with a set of available resource configurations for multi-hop communication (e.g., backhaul communication between nodes). The set of available resource configurations may provide a wireless resource allocation that will be used for communication between the nodes. In some cases, the central entity 405 may optionally provide an initial configuration or a default configuration that will be used for initial communication. At 425, the first node 410 and the second node 415 may exchange wireless communication (e.g., backhaul communication, relay access link communication in a multi-hop network, etc.) according to a first configuration in the set of available resource configurations.

[0093] Optionally, at 430, the central entity 405 may determine to update a resource configuration used by one or more of the first node 410 or the second node 415. In such a case, at 435, the central entity 405 may send a resource configuration update indication to one or both of the first node 410 or the second node 415. In some cases, the central entity 405 may determine to update the resource configuration based on one or more network conditions, such as the type or priority of the traffic being exchanged, one or more changes in the network topology (e.g., due to other relay nodes going online or offline), beam updates, power saving modes, etc.

[0094] At 440, the first node 410 may identify an updated resource configuration for communication with the second node 415. Such identification may be based on the received indication in the case where the first node 410 receives an update indication from the central entity 405. In other cases, as discussed herein, the first node 410 may identify the updated resource configuration based on one or more operating conditions or other configuration changes of the first node 410. At 445, the first node 410 may send a resource configuration update indication (e.g., in DCI or in a MAC-CE transmission to the second node 415) to the second node 415. Based on the updated configuration, at 450, the first node 410 and the second node 415 may exchange wireless communication (e.g., backhaul communication, relay access link communication in a multi-hop network, etc.) according to a second configuration in the set of available resource configurations indicated in the resource configuration update indication.

[0095] Optionally, at 455, the second node 415 may identify the updated resource configuration. In some cases, as discussed herein, the second node 415 may be a child node and may identify the updated resource configuration based on one or more operating conditions or other configuration changes of the second node 415. In such cases, at 460, the second node 415 may send a resource configuration update or request indication (e.g., in UCI or a MAC-CE transmission) to the first node 410. In some cases, the first node 410 may determine the updated resource configuration based on the update or request indication. At 470, the first node 410 may send a responsive resource configuration indication or request grant indication to the second node 415, and subsequently the first node 410 and the second node 415 may communicate according to a third configuration. In some cases, at 475, the first node 410 may provide a configuration status indication to the central entity.

[0096] Figure 5 FIG. 500 shows a diagram of a device 505 supporting resource configuration management in wireless communication in accordance with aspects of the present disclosure.

[0098] The communication manager 515 may operate in a first node of a multi-hop wireless network and may identify a first pre-configured resource allocation in a set of pre-configured resource allocations available for communication between the first node and one or more of a parent node or a child node. After using the first pre-configured resource allocation, the communication manager 515 may select a second pre-configured resource allocation in the set of pre-configured resource allocations for communication with one or more of a parent node or a child node and may use the second pre-configured resource allocation to communicate with one or more of a parent node or a child node.

[0099] The communication manager 515 may operate in a central entity of a multi-hop wireless network and may configure a first node of the multi-hop wireless network with a set of pre-configured resource allocations, where each pre-configured resource allocation in the set of pre-configured resource allocations indicates different wireless resources available for communication between the first node and one or more other nodes, and may provide the set of pre-configured resource allocations to the first node. The communication manager 515 may be an example of aspects of the communication manager 810 or 910 described herein.

[0100] The communication manager 515 or its sub-components may be implemented in hardware, code executed by a processor (e.g., software or firmware), or any combination thereof.

Each of these components may communicate with each other (e.g., via one or more buses).

[0104] The receiver 610 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to resource configuration management in wireless communications, etc.). The information may be passed to other components of the device 605. The receiver 610 may be an example of aspects of the transceiver 820 or 920 described with reference to Figure 8 and 9 The receiver 610 may utilize a single antenna or a set of antennas.

The communication manager 615 may include a resource configuration manager 620, a resource selection manager 625, and a relay communication manager 630. The communication manager 615 may be an example of aspects of the communication manager 810 or 910 described herein.

[0106] In some cases, the resource configuration manager 620 may operate in a first node of a multi-hop wireless network and may identify a first preconfigured resource allocation in a set of preconfigured resource allocations available for communication between the first node and one or more of a parent node or a child node. The resource selection manager 625 may select, after using the first preconfigured resource allocation, a second preconfigured resource allocation in the set of preconfigured resource allocations for communication with one or more of a parent node or a child node. The relay communication manager 630 may use the second preconfigured resource allocation to communicate with one or more of a parent node or a child node.

[0107] In some cases, the resource configuration manager 620 may operate in a central entity of a multi-hop wireless network and may configure a first node of the multi-hop wireless network with a set of preconfigured resource allocations, where each preconfigured resource allocation in the set of preconfigured resource allocations indicates a different wireless resource available for communication between the first node and one or more of the other nodes. The relay communication manager 630 may provide the set of preconfigured resource allocations to the first node.

[0108] The transmitter 635 may send signals generated by other components of the device 605. In some examples, the transmitter 635 may be co-located with the receiver 610 in a transceiver module. For example, the transmitter 635 may be an example of aspects of the transceiver 820 or 920 as described with reference to Figure 8 and 9 The transmitter 635 may utilize a single antenna or a set of antennas.

[0109] Figure 7 FIG. 700 shows a communication manager 705 that supports resource configuration management in wireless communications, in accordance with aspects of the present disclosure. The communication manager 705 may be an example of aspects of the communication manager 515, the communication manager 615, or the communication manager 810 described herein. The communication manager 705 may include a resource configuration manager 710, a resource selection manager 715, a relay communication manager 720, a configuration report manager 725, a resource configuration mapping component 730, and a handover criteria manager 735. Each of these modules may communicate directly or indirectly with each other (e.g., via one or more buses).

[0110] A resource configuration manager 710 may operate in a first node of a multi-hop wireless network and may identify a first pre-configured resource allocation in a set of pre-configured resource allocations available for communication between the first node and one or more of a parent node or child nodes. In some examples, the resource configuration manager 710 may receive configuration information from a central entity of the multi-hop wireless network, the configuration information indicating each pre-configured resource allocation in the set of pre-configured resource allocations available for communication between the first node and one or more parent nodes or child nodes. In some examples, the resource configuration manager 710 may receive an initial configuration from the central entity, the initial configuration indicating that the first pre-configured resource allocation will be used for initial communication with one or more of a parent node or child nodes. In some cases, the first pre-configured resource allocation is a default resource allocation provided in the configuration information. A resource selection manager 715 may, after using the first pre-configured resource allocation, select a second pre-configured resource allocation in the set of pre-configured resource allocations for communication with one or more of a parent node or child nodes. In some examples, the resource selection manager 715 may receive an indication of an updated resource allocation at a parent node or one of the child nodes, and wherein the selection of the second pre-configured resource allocation is based on the updated resource allocation.

[0111] In some examples, a resource configuration manager 710 may operate in a central entity of a multi-hop wireless network and may configure a first node of the multi-hop wireless network with a set of pre-configured resource allocations, wherein each pre-configured resource allocation in the set of pre-configured resource allocations indicates different wireless resources available for communication between the first node and one or more of other nodes. In some examples, a resource selection manager 715 may provide an initial configuration to the first node, the initial configuration indicating that a first pre-configured resource allocation in the set of pre-configured resource allocations will be used for initial communication with one or more of other nodes. In some examples, the resource selection manager 715 may determine that a second pre-configured resource allocation will be used for further communication with one or more of other nodes. In some examples, the resource selection manager 715 may provide an indication to the first node regarding a change to the second pre-configured resource allocation. In some examples, the resource selection manager 715 may receive an indication of an acknowledgement from the first node. In some examples, the resource selection manager 715 may receive an indication from the first node that a second pre-configured resource allocation in the set of pre-configured resource allocations will be used for further communication with one or more of other nodes.

[0112] In some cases, the selection of the second pre-configured resource allocation is based on receiving an indication to change to the second pre-configured resource allocation from a central entity of a multi-hop wireless network. In some cases, the indication is received in a downlink control information transmission, an uplink control information transmission, a media access control (MAC) control element (CE), or any combination thereof. In some cases, the indication of the updated resource allocation also indicates that the first node will select the second pre-configured resource allocation.

[0113] In some cases, the first node is a first parent node, and the indication of the updated resource allocation can be received from a first child node, and wherein the indication of the updated resource allocation is a request from the first child node to use the updated resource allocation. In some cases, the first node sends a response to the first child node indicating that the request is granted and indicating the second pre-configured resource allocation of the first node. In some cases, the first pre-configured resource allocation is the default resource allocation provided in the configuration information provided to the first node.

[0114] The relay communication manager 720 can use the second pre-configured resource allocation to communicate with one or more of a parent node or a child node. In some examples, the relay communication manager 720 can provide a set of pre-configured resource allocations to the first node.

[0115] The configuration reporting manager 725 can send an indication that the second pre-configured resource allocation has been selected for communication by the first node to one or more of a parent node, a child node, or a central entity of a multi-hop wireless network.

[0116] The resource configuration mapping component 730 can provide a mapping for certain configurations. In some cases, the first node is a first child node, and the indication of the updated resource allocation is received from a first parent node, and wherein the second pre-configured resource allocation is selected based on a mapping of a subset of a set of pre-configured resource allocations that is compatible with the updated resource allocation of the first parent node. In some cases, the mapping of the subset of the set of pre-configured resource allocations that is compatible with the updated resource allocation of the first parent node can be explicitly indicated in the configuration information or determined based on one or more mapping rules, and the configuration information is used to configure the set of pre-configured resource allocations.

[0117] The handover criteria manager 735 can determine that one or more pre-configured criteria for handover of the pre-configured resource allocation have been met, and wherein the selection of the second pre-configured resource allocation is based on the one or more pre-configured criteria. In some cases, the one or more pre-configured criteria are received in the configuration information from a central entity of a multi-hop wireless network.

[0118] In some cases, one or more preconfigured criteria are based on beams used for communication between a first node and one or more of a parent node or a child node, and wherein a first preconfigured resource allocation is associated with a first beam and a second preconfigured resource allocation is associated with a second beam. In some cases, the first preconfigured resource allocation and the second preconfigured resource allocation are associated with different multiplexing parameters of the associated first beam and second beam. In some cases, one or more preconfigured criteria are based on a power saving mode used for communication between a first node and one or more of a parent node or a child node, and wherein a first preconfigured resource allocation is associated with a first power saving mode and a second preconfigured resource allocation is associated with a second power saving mode. In some cases, one or more preconfigured criteria are based on a topology state of one or more of a first node, a parent node, or a child node, and wherein a first preconfigured resource allocation is associated with a first topology state and a second preconfigured resource allocation is associated with a second topology state. In some cases, one or more preconfigured criteria are based on a quality of service associated with communication between a first node and one or more of a parent node or a child node, and wherein a first preconfigured resource allocation is associated with a first quality of service and a second preconfigured resource allocation is associated with a second quality of service.

The code 835 may be stored in a non-transitory computer-readable medium (e.g., system memory or other types of memory). In some cases, the code 835 may not be directly executable by the processor 840, but may cause a computer (e.g., when compiled and executed) to perform the functions described herein.

[0128] Figure 9 A diagram of a system 900 including a device 905 that supports resource configuration management in wireless communication, in accordance with aspects of the present disclosure.

[0168] The information and signals described herein can be represented using any of a variety of different technologies and methods. For example, the data, instructions, commands, information, signals, bits, symbols, and chips that may be referred to throughout the description can be represented by voltage, current, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0169] Various illustrative blocks and modules described in connection with the present disclosure can be implemented or performed using a general-purpose processor, DSP, ASIC, FPGA, or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. The general-purpose processor can be a microprocessor, but in the alternative, the processor can be any conventional processor, controller, microcontroller, or state machine. The processor can also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration).

[0170] The functions described herein can be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functions can be stored on or transmitted via a computer-readable medium as one or more instructions or code. Other examples and implementations are within the scope of the present disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these items. The features implementing the functions can also be physically located in various positions, including being distributed such that portions of the functions are implemented at different physical locations.

[0171] Computer-readable media includes both non-transitory computer storage media and communication media, where communication media includes any medium that facilitates transfer of a computer program from one place to another. Non-transitory storage media can be any available media that can be accessed by a general purpose or special purpose computer. By way of example, and not limitation, non-transitory computer-readable media can include random access memory (RAM), read only memory (ROM), electrically erasable programmable ROM (EEPROM), flash memory, compact disc ROM (CD-ROM) or other optical disc storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code units in the form of instructions or data structures and that can be accessed by a general purpose or special purpose computer, or a general purpose or special purpose processor. Additionally, any connection is properly termed a computer-readable medium. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of the medium. As used herein, disk and disc include CD, laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Blu-ray disc, where disks typically reproduce data magnetically, while discs reproduce data optically using lasers.

[0172] As used herein (including in the claims), the "or" as used in a list of items (e.g., a list of items that ends with a phrase such as "at least one of" or "one or more of") indicates an inclusive list, such that a list of at least one of A, B, or C, for example, means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). As used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, without departing from the scope of the present disclosure, an exemplary step described as "based on condition A" may be based on both condition A and condition B. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".

[0173] In the drawings, similar components or features may have the same reference numeral. Additionally, various components of the same type may be distinguished by following the reference numeral with a dash and a second numeral, which is used to differentiate between similar components. If only the first reference numeral is used in the specification, the description applies to any one of the similar components having the same first reference numeral, regardless of the second numeral or any other subsequent numerals.

[0174] The description set forth herein with reference to the drawings describes example configurations and does not represent all examples that may be implemented or that are within the scope of the claims. The term "exemplary" as used herein means "serving as an example, instance, or illustration" and not "preferred" or "advantageous over other examples". For the purpose of providing an understanding of the described technology, the detailed description includes specific details. However, the technology may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
