Cross Reference to Related Applications

This patent application claims priority from U.S. provisional patent application No.63/168,014, filed on 3/30/2021, entitled "TECHNIQUES FOR SUPPORTING DYNAMIC FREQUENCY DIVISION MULTIPLEXING WITHIN CARRIER (technique for supporting dynamic frequency division multiplexing within a carrier)", and U.S. patent application No.17,682,266 filed on 28/2022, entitled "TECHNIQUES FOR SUPPORTING DYNAMIC FREQUENCY DIVISION MULTIPLEXING WITHIN CARRIER (technique for supporting dynamic frequency division multiplexing within a carrier)", which are assigned to the assignee hereof and are expressly incorporated herein by reference for all purposes.

Background

Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to communication using dynamic Frequency Division Multiplexing (FDM).

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include Code Division Multiple Access (CDMA) systems, time Division Multiple Access (TDMA) systems, frequency Division Multiple Access (FDMA) systems, and Orthogonal Frequency Division Multiple Access (OFDMA) systems, as well as single carrier frequency division multiple access (SC-FDMA) systems.

These multiple access techniques have been adopted in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the urban, national, regional, and even global levels. For example, fifth generation (5G) wireless communication technologies, which may be referred to as 5G new radio (5G NR), are designed to expand and support diverse usage scenarios and applications relative to current mobile network architectures. In an aspect, a 5G communication technique may include: an enhanced mobile broadband for people-centric use cases for accessing multimedia content, services, and data; ultra Reliable Low Latency Communications (URLLC) with certain specifications regarding latency and reliability; and large-scale machine type communications, which may allow for a very large number of connected devices and transmission of relatively small amounts of non-delay sensitive information.

In wireless communication technologies, such as 5G NR, an Integrated Access and Backhaul (IAB) network may include IAB nodes in communication with each other and/or with an upstream IAB donor node or a downstream User Equipment (UE). The IAB node may use a Mobile Termination (MT) function to communicate with an upstream node and may use a Distributed Unit (DU) function distributed from a Centralized Unit (CU) function at the IAB donor node to communicate with a downstream node. A CU may schedule communications and/or associated resources in time and/or frequency for various downstream IAB nodes or UEs.

Detailed Description

Various aspects are now described with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that such aspect(s) may be practiced without these specific details.

The described features generally relate to implementing communication for nodes of a wireless network using dynamic Frequency Division Multiplexing (FDM) within Component Carriers (CCs). For example, within a CC, different sets of Resource Blocks (RBs) may be allocated to nodes for wireless communication. The upstream node configuring the node may indicate a configuration associated with determining whether to allocate the different sets of RBs to the node.

In some wireless communication technologies, such as fifth generation (5G) New Radio (NR), an Integrated Access and Backhaul (IAB) network may be provided that includes a plurality of IAB nodes in communication with each other. The IAB node may communicate with the IAB donor directly or indirectly (e.g., via one or more other IAB nodes). The IAB donor may include a Centralized Unit (CU) that schedules or allocates resources for the IAB nodes downstream from the IAB donor (e.g., for one or more associated cells of the IAB nodes). A CU may schedule or allocate time and/or frequency resources. For example, a resource may comprise a set of Resource Blocks (RBs) within one or more symbols, where a symbol may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a single carrier FDM (SC-FDM) symbol, or the like. The symbol may include a portion of a frequency defined over a period of time, such as a CC. The symbol may be divided into a plurality of RBs in frequency. In addition, the resources may include one or more slots, where each slot includes a plurality of symbols.

Aspects described herein relate to an IAB node using dynamically allocated frequency resources for wireless communication. In one aspect, an upstream node may allocate frequency resources for an IAB node and/or individual IAB nodes to facilitate dynamic FDM multiplexing of communications for the IAB node within a CC. The IAB node may receive a configuration from the upstream node, the configuration may indicate a plurality of resource availability combinations available for allocation to the IAB node, and the IAB node may receive another indication of one or more of the plurality of resource availability combinations to be used by the IAB node when communicating in the wireless network. In aspects described herein, an IAB node may receive an indication of a portion (e.g., one or more RB sets) of frequency resources within a CC to be used, which may not include all RBs in the CC. For example, the configuration of multiple resource availability combinations may indicate that the combinations apply to one or more particular RB sets. In another example, an indication of one or more resource availability combinations to be used or another signal received by the IAB node may indicate one or more particular RB sets to which the one or more resource availability combinations are to be applied.

In this regard, implementing dynamic FDM resource allocation may allow for enhanced duplex capabilities, such as Space Division Multiplexing (SDM) half duplex and SDM full duplex, by operating the IAB nodes simultaneously, which may increase the communication throughput of the IAB nodes. In addition, dynamic FDM resource allocation within a CC may allow multiplexing communications of multiple IAB nodes within the CC, which may also increase the communication throughput of the IAB nodes. The increase in throughput may be extended to downstream nodes and devices, such as UEs communicating with the IAB node, which may improve the user experience at the UE.

The features described will be presented in more detail below with reference to fig. 1-12.

As used in this disclosure, the terms "component," "module," "system," and the like are intended to include a computer-related entity, such as but not limited to hardware, firmware, a combination of hardware and software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a computing device and the computing device can be a component. One or more components may reside within a process and/or thread of execution and a component may be localized on one computer and/or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon. The components may communicate by way of local and/or remote processes such as in accordance with a signal having one or more data packets such as data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems by way of the signal.

The techniques described herein may be used for various wireless communication systems such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other systems. The terms "system" and "network" may be used interchangeably in general. A CDMA system may implement a radio technology such as CDMA2000, universal Terrestrial Radio Access (UTRA), and the like. CDMA2000 covers IS-2000, IS-95, and IS-856 standards. IS-2000 release 0 and a are commonly referred to as CDMA2000 1X, etc. IS-856 (TIA-856) IS commonly referred to as CDMA2000 1xEV-DO, high Rate Packet Data (HRPD), or the like. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. TDMA systems may implement radio technologies such as global system for mobile communications (GSM). OFDMA systems may implement, for example, ultra Mobile Broadband (UMB), evolved UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, flash-OFDM ^TM And equal radio technologies. UTRA and E-UTRA are part of Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and LTE-advanced (LTE-A) are new UMTS releases that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-a and GSM are described in the literature from an organization named "third generation partnership project" (3 GPP). CDMA2000 and UMB are described in the literature from an organization named "third generation partnership project 2" (3 GPP 2). The techniques described herein can be used with the above-mentioned systems The system and radio technology may also be used for other systems and radio technologies, including cellular (e.g., LTE) communications over a shared radio spectrum band. However, the following description describes an LTE/LTE-a system for purposes of example, and LTE terminology is used in much of the description below, but these techniques may also be applied outside of LTE/LTE-a applications (e.g., to fifth generation (5G) New Radio (NR) networks or other next generation communication systems).

The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made in the function and arrangement of elements discussed without departing from the scope of the disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Additionally, features described with reference to some examples may be combined in other examples.

The various aspects or features will be presented in terms of systems that may include a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. Combinations of these approaches may also be used.

Fig. 1 is a diagram illustrating an example of a wireless communication system and an access network 100. A wireless communication system, also referred to as a Wireless Wide Area Network (WWAN), may include a base station 102, a UE 104, an Evolved Packet Core (EPC) 160, and/or a 5G core (5 GC) 190. Base station 102 may include macro cells (high power cell base stations) and/or small cells (low power cell base stations). The macrocell may include a base station. Small cells may include femtocells, picocells, and microcells.

A base station 102 configured for 4G LTE, which may be collectively referred to as an evolved Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (E-UTRAN), may interface with the EPC 160 through a backhaul link 132 (e.g., using an S1 interface). A base station 102 configured for 5G NR, which may be collectively referred to as a next generation RAN (NG-RAN), may interface with a 5gc 190 over a backhaul link 184. Among other functions, the base station 102 may perform one or more of the following functions: user data delivery, radio channel ciphering and ciphering, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio Access Network (RAN) sharing, multimedia Broadcast Multicast Services (MBMS), subscriber and equipment tracking, RAN Information Management (RIM), paging, positioning, and delivery of alert messages. The base stations 102 may communicate with each other directly or indirectly (e.g., through EPC 160 or 5gc 190) over the backhaul link 134 (e.g., using an X2 interface). The backhaul link 134 may be wired or wireless.

The base station 102 may communicate wirelessly with one or more UEs 104. Each base station 102 may provide communication coverage for a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, the small cell 102 'may have a coverage area 110' that overlaps with the coverage area 110 of one or more macro base stations 102. A network comprising both small cells and macro cells may be referred to as a heterogeneous network. The heterogeneous network may also include a home evolved node B (eNB) (HeNB) that may provide services to a restricted group, which may be referred to as a Closed Subscriber Group (CSG). The communication link 120 between the base station 102 and the UE 104 may include Uplink (UL) (also known as reverse link) transmissions from the UE 104 to the base station 102 and/or Downlink (DL) (also known as forward link) transmissions from the base station 102 to the UE 104. Communication link 120 may use multiple-input multiple-output (MIMO) antenna techniques including spatial multiplexing, beamforming, and/or transmit diversity. These communication links may be through one or more CCs. For each CC allocated in a carrier aggregation up to yxmhz (e.g., for x CCs) in total for transmission in the DL and/or UL directions, the base station 102/UE 104 may use a spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400MHz, etc.) bandwidth. These CCs may or may not be adjacent to each other. The allocation of CCs may be asymmetric with respect to DL and UL (e.g., more or fewer CCs may be allocated to DL than UL). The CCs may include a primary CC and one or more secondary CCs. The primary CC may be referred to as a primary cell (PCell) and the secondary CC may be referred to as a secondary cell (SCell).

In another example, certain UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use the DL/UL WWAN spectrum. The D2D communication link 158 may use one or more side link channels such as a physical side link broadcast channel (PSBCH), a physical side link discovery channel (PSDCH), a physical side link shared channel (PSSCH), and a physical side link control channel (PSCCH). D2D communication may be through a variety of wireless D2D communication systems such as, for example, flashLinQ, wiMedia, bluetooth, zigBee, wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

The wireless communication system may further include a Wi-Fi Access Point (AP) 150 in communication with a Wi-Fi Station (STA) 152 via a communication link 154 in a 5GHz unlicensed spectrum. When communicating in the unlicensed spectrum, the STA 152/AP 150 may perform a Clear Channel Assessment (CCA) prior to communication to determine whether the channel is available.

The small cell 102' may operate in licensed and/or unlicensed spectrum. When operating in unlicensed spectrum, the small cell 102' may employ NR and use the same 5GHz unlicensed spectrum as that used by the Wi-Fi AP 150. Small cells 102' employing NR in the unlicensed spectrum may push up access network coverage and/or increase access network capacity.

Whether small cell 102' or a large cell (e.g., macro base station), base station 102 may include an eNB, g B node (gNB), or other type of base station. Some base stations, such as the gNB 180, may operate in the legacy sub-6 GHz spectrum, millimeter wave (mmW) frequencies, and/or near mmW frequencies to communicate with the UE 104. When the gNB 180 operates in mmW or near mmW frequencies, the gNB 180 may be referred to as a mmW base station. Extremely High Frequency (EHF) is a part of the RF in the electromagnetic spectrum. EHF has a wavelength in the range of 30GHz to 300GHz and between 1 mm and 10 mm. The radio waves in this band may be referred to as millimeter waves. The near mmW can be extended down to a 3GHz frequency with a wavelength of 100 mm. The ultra-high frequency (SHF) band extends between 3GHz and 30GHz, which is also known as a centimeter wave. Communications using mmW/near mmW radio frequency bands have extremely high path loss and short range. The mmW base station 180 may utilize beamforming 182 with the UE 104 to compensate for extremely high path loss and short range.

EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a serving gateway 166, a Multimedia Broadcast Multicast Service (MBMS) gateway 168, a broadcast multicast service center (BM-SC) 170, and a Packet Data Network (PDN) gateway 172.MME 162 may be in communication with a Home Subscriber Server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. Generally, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are communicated through the serving gateway 166, which serving gateway 166 itself is connected to the PDN gateway 172. The PDN gateway 172 provides UE IP address allocation as well as other functions. The PDN gateway 172 and BM-SC 170 are connected to an IP service 176.IP services 176 may include the internet, intranets, IP Multimedia Subsystem (IMS), PS streaming services, and/or other IP services. The BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. The BM-SC 170 may be used as an entry point for content provider MBMS transmissions, may be used to authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and may be used to schedule MBMS transmissions. The MBMS gateway 168 may be used to distribute MBMS traffic to base stations 102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service and may be responsible for session management (start/stop) and for collecting eMBMS related charging information.

The 5gc 190 may include an access and mobility management function (AMF) 192, other AMFs 193, a Session Management Function (SMF) 194, and a User Plane Function (UPF) 195. The AMF 192 may be in communication with a Unified Data Management (UDM) 196. The AMF 192 may be a control node that handles signaling between the UE 104 and the 5gc 190. In general, AMF 192 may provide QoS flows and session management. User Internet Protocol (IP) packets (e.g., from one or more UEs 104) may be communicated via the UPF 195. The UPF 195 may provide UE IP address assignment for one or more UEs, as well as other functions. The UPF 195 is connected to an IP service 197. The IP services 197 may include the internet, intranets, IP Multimedia Subsystem (IMS), PS streaming services, and/or other IP services.

A base station may also be called a gNB, a node B, an evolved node B (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a Basic Service Set (BSS), an Extended Service Set (ESS), a transmission-reception point (TRP), or some other suitable terminology. Base station 102 provides an access point for UE 104 to EPC 160 or 5gc 190. Examples of UEs 104 include a cellular telephone, a smart phone, a Session Initiation Protocol (SIP) phone, a laptop, a Personal Digital Assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electricity meter, an air pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor/actuator, a display, or any other similar functional device. Some UEs 104 may be referred to as IoT devices (e.g., parking timers, oil pumps, ovens, vehicles, heart monitors, etc.). IoT UEs may include Machine Type Communication (MTC)/enhanced MTC (eMTC), also known as Category (CAT) -M, CAT M1) UEs, NB-IoT (also known as CAT NB 1) UEs, and other types of UEs. In this disclosure, eMTC and NB-IoT may refer to future technologies that may evolve from or may be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), eMTC (large scale MTC), etc., while NB-IoT may include eNB-IoT (enhanced NB-IoT), feNB-IoT (further enhanced NB-IoT), etc. The UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, or some other suitable terminology.

Referring to fig. 2, an example of another wireless communication access network 200 including an IAB node is depicted in accordance with various aspects described herein. The wireless communication access network 200 may include one or more upstream nodes 202, which may include a gNB or other base station (e.g., base station 102), an IAB node, an IAB donor, a CU, a DU, etc., that may communicate with one or more UEs 104 and/or IAB nodes 204.

The IAB node 204 may be located between the one or more upstream nodes 202 (and/or one or more intervening upstream IAB nodes) and the UE 104 (and/or one or more intervening downstream IAB nodes). In an example, the IAB node 204 may operate in half duplex or full duplex, as further described herein. In an aspect, the IAB node 204 may include a modem 240 and a communication component 242 for communicating in a wireless network over dynamically allocated frequency resources within CCs. Additionally, in an aspect, upstream node 202 may include a modem 244 and a scheduling component 246 for scheduling downstream IAB nodes to communicate in the wireless network over dynamically allocated frequency resources within the CC. In an example, the upstream node 202 may be an IAB donor with a CU that schedules a downstream IAB node, or the upstream node may be an IAB node, where the scheduling may originate from an IAB donor with a CU or other node upstream of the upstream node 202.

In some wireless communication networks, the functionality of a base station and/or other components of the network may be distributed across multiple entities. Fig. 3 illustrates an example of a wireless communication network 300 that may be utilized in some aspects of the present disclosure. In this example, the wireless communication network 300 may include an IAB network with network entities such as an IAB donor 302 coupled to a remote network 304 such as a main backhaul network or a mobile core network (e.g., EPC, 5GC, etc.). In the wireless communication network 300, wireless spectrum may be used for a Backhaul (BH) link 306 between an IAB donor 302 (or other upstream node) and an IAB node 204, and for an access link 310 between the IAB node 204 and a UE 104 (or other downstream node). BH link 306 may be made through a Uu interface or other suitable wireless communication interface between an upstream node DU (e.g., DU 316 of IAB donor 302 in this example) and MT 318 of IAB node 204. In addition, there may be an F1 interface or other suitable interface between CU 314 of IAB donor 302 and DU 320 of IAB node 204. In addition, for example, access link 310 may be similar to BH link 306 between IAB node 204 and its upstream node (IAB donor 302 in this example), and may be over a Uu radio interface or some other suitable wireless communication interface. In some examples, the wireless spectrum may utilize mmW frequencies and/or sub-6 GHz carrier frequencies. In an example, the IAB donor 302 may include a wire (e.g., fiber, coaxial cable, ethernet, copper wire), microwave, or another suitable link to the remote network 304.

In some examples (e.g., as shown in fig. 3), IAB donor 302 may include CU 314 and one or more DUs 316.CU 314 may be configured to operate as a centralized network node (or central entity) within wireless communication network 300. For example, CU 314 may include Radio Resource Control (RRC) layer functionality and Packet Data Convergence Protocol (PDCP) layer functionality to control/configure other nodes (e.g., IAB nodes and UEs) within network 300. In some aspects, RRC signaling may be used for various functions including, as one example, setting up and releasing user data bearers. In some examples, RRC signaling messages may be transmitted on signaling bearers (e.g., SRB1 and SRB 2).

The DU 316 may be configured to operate as a scheduling entity to schedule a scheduled entity (e.g., an IAB node or UE) of the base station 102 with frequency and/or time resources for wireless communication. For example, the DU 316 may operate as a scheduling entity to schedule the IAB node 204 and the UE 104. In some examples, DU 316 may include Radio Link Control (RLC), medium Access Control (MAC), and Physical (PHY) layer functionality to enable operation as a scheduling entity.

The F1 interface may provide a mechanism to interconnect CUs 314 (e.g., PDCP layer and higher layer) and DUs 316 (e.g., RLC layer and lower layer). In some aspects, the F1 interface may provide control plane and user plane functions (e.g., interface management, system information management, UE context management, RRC messaging, etc.). F1AP is an application protocol for F1, which in some examples defines a signaling procedure for F1. The F1 interface supports F1-C on the control plane and F1-U on the user plane.

To facilitate wireless communication between the IAB donor 302 (or remote network 304) and a UE (e.g., UE 104), the IAB node 204 may be configured to operate as a scheduled entity. The IAB node 204 may include a Mobile Termination (MT) unit 318 to implement scheduled entity functionality. For example, the MT unit 318 may include UE functionality to connect to and be scheduled by an upstream node (which may be the IAB donor 302 or another IAB node) using frequency and/or time resources for wireless communication. The IAB node 204 also includes a DU 320 that facilitates communication between the IAB donor 302 (or other upstream node or remote network 304) and the UE 104. In an example, DU 320 may include one or more cells to facilitate communication with one or more UEs or other downstream IAB nodes.

Fig. 4 illustrates an example of a configuration of duplex capability of an IAB node. In a Time Division Multiplexing (TDM) configuration 400, an IAB node 204 may have an active parent BH link with an upstream node 202 or an active child link with a UE and/or other downstream IAB nodes at a given point in time. In some examples, enhanced duplex capability may be supported to allow simultaneous operation on a pair of MT CC and DU cells. For example, in SDM half-duplex configuration 402, IAB node 204 may communicate using MT-RX (with upstream node 202) and DU-RX (with downstream node) simultaneously, or MT-TX (with upstream node 202) and DU-TX (with downstream node) simultaneously at a given point in time. In SDM full duplex configuration 404, for example, IAB node 204 may communicate using MT-RX (with upstream node 202) and DU-RX (with downstream node) simultaneously, and/or using MT-TX (with upstream node 202) and DU-TX (with downstream node) simultaneously at a given point in time.

Fig. 5 illustrates an example of a resource configuration for an IAB node. In resource configuration 500, upstream node 202 may schedule IAB node 204 with a resource allocation of time and/or frequency resources for communication with the upstream node 202 and a resource allocation of time and/or frequency resources for communication with UE 104 (or other downstream nodes). In resource configuration 500, for example, upstream node 202 may configure IAB node 204 to have one or more symbols 502 indicated as hard ("H"), which means that IAB node 204 may use the one or more symbols 502 to communicate with upstream node 202, one or more symbols 504 indicated as unavailable ("NA"), which means that IAB node 204 may not use the one or more symbols 504 to communicate with upstream node 202, and resource allocation of one or more other symbols 506 indicated as H, where symbols 502, 504, 506 may be consecutive in time and may include one CC. In addition, in resource configuration 500, upstream node 200 may configure IAB node 204 to have resource allocations of one or more symbols 512 indicated as NA, one or more symbols 514 indicated as soft ("S") (which means that IAB node 204 may conditionally use the one or more symbols 514 to communicate with upstream node 202), and one or more other symbols 516 indicated as H, where symbols 502, 504, 506 may be consecutive in time and may include one CC, for example. In an example, for symbols indicated as S, the upstream node 202 or another node may use an implicit indication (e.g., via Downlink Control Information (DCI) 2_5, implicit determination that no effect on the MT, etc.) to dynamically control whether the symbols are used for communication between the IAB node 204 and the upstream node 202. In this regard, for example, semi-static resource configuration (which may configure symbols as H, NA or S) may support FDM granularity of CCs (in terms of DU cells), while dynamic signaling (such as DCI 2_5) is used for dynamic availability indication to indicate whether S symbols may be used.

In an example, the upstream node 202 may use RRC signaling to communicate the semi-static resource configuration. The RRC signaling and/or the configuration may originate at the upstream node 202 (in the case where the upstream node 202 is an IAB donor otherwise having a CU), or may originate from a node upstream of the upstream node, etc. The semi-static resource configuration may include an availability combination table (e.g., availabilities combinesbacell (cell availability combination) table defined in 5G NR), where the table may have rows corresponding to a plurality of resource availability combinations identified by an index (e.g., 0..511) and columns for slot indexes (e.g., 0 … 255) corresponding in time to slots such that a given resource availability combination may define a resource availability value for each of a plurality of slots (e.g., up to 256 slots). For a given time slot in a given combination of resource availability, the resource availability value may comprise one of the following values 0-7, defined as a resource availability table in 5G NR (e.g., in third generation partnership project (3 GPP) Technical Specification (TS) 38.213):

in an example, the upstream node 202 may transmit a group common Physical Downlink Control Channel (PDCCH) that may indicate an availability combination index into an availabilities communication percell table in DCI format 2_5 and for a given IAB node or one or more cells of that IAB node. Accordingly, given the index indicated in DCI format 2_5 and the value of the resource availability table at the slot index in the row corresponding to that index, IAB node 204 may determine which resources are available in the slot.

Aspects described herein relate to defining a resource allocation granularity (e.g., as a starting point for a set of N RBs) for frequency domain resources within a CC, which may include frequency domain expansion for soft resources and enhancements for DCI format 2_5 to support dynamic indication of availability of soft frequency resources. In an example, the upstream node 202 may configure the resources in this regard using separate indications of time and frequency resources (e.g., different fields, radio Network Temporary Identifiers (RNTIs) or different DCIs) or joint indications of time and frequency resources (e.g., expansion of FDM across CCs, possible constraints on frequency bands/minimum bandwidths for FDM operation (e.g., FR2 100MHz +, etc.)).

In an example, frequency domain resource management within a CC may be supported by an allocated set of RBs, which may be similar to the concept of bandwidth part (BWP) of a DU cell. For example, a separate time domain H/S/NA configuration may be applied to each BWP (e.g., each RB set) of the DU cell to extend the IAB resource management framework from each DU cell to each "DU RB set," which may be configured by the CU as a coherent RB set within the DU cell. In another example, an existing time domain H/S/NA configuration and an additional second configuration across bwtps (e.g., RB sets) may be used with each BWP (e.g., RB set) indicated with a type value, such that interpretation of the time domain H/S/NA at the BWP (e.g., RB set) may depend on the type value indicated for that BWP (e.g., RB set).

In an example, in resource configuration 520, upstream node 202 may schedule IAB node 204 with a resource allocation for communication with upstream node 202 and a resource allocation for communication with UE 104 (or other downstream node). In resource allocation 520, upstream node 202 may configure IAB node 204 with a resource allocation of one or more RB sets 522 indicated as H in a first set of one or more symbols and one or more RB sets 532 indicated as NA in the first set of one or more symbols, wherein the one or more RB sets 522 and the one or more RB sets 532 may be within a CC, for example. In addition, in resource configuration 520, upstream node 202 may configure IAB node 204 with resource allocations for one or more RB sets 524 of the second set of one or more symbols indicated as NA and one or more RB sets 534 of the second set of one or more symbols indicated as H, one or more RB sets 526 of the third set of one or more symbols indicated as H, and one or more RB sets 536 of the third set of one or more symbols indicated as H, for example. In addition, in resource configuration 520, upstream node 202 may configure IAB node 204 with a resource allocation of one or more RB sets 542 of the first set of one or more symbols indicated as NA, one or more RB sets 544 of the second set of one or more symbols indicated as S, and one or more RB sets 552 of the set of one or more symbols (which may include the first set of one or more symbols and the second set of one or more symbols) indicated as H, one or more RB sets 546 of the third set of one or more symbols indicated as H, and one or more RB sets 554 of the third set of one or more symbols indicated as S, for example. Aspects described herein relate to signaling support for dynamic FDM within a CC (e.g., dynamically signaling whether an IAB node 204 may use a set of RBs 544 for S symbols and/or a set of RBs 554 for S symbols).

Turning now to fig. 6-12, aspects are depicted with reference to one or more components and one or more methods that may perform actions or operations described herein, where aspects in dashed lines may be optional. Although the operations described below in fig. 8-9 are presented in a particular order and/or as performed by example components, it should be understood that the order of such actions and the components performing the actions may vary depending on the implementation. Moreover, it should be appreciated that the acts, functions, and/or components described below may be performed by a specially programmed processor, a processor executing specially programmed software or computer readable media, or by any other combination of hardware and/or software components capable of performing the described acts or functions.

With reference to fig. 6, one example of an implementation of the iab node 204 may include various components, some of which have been described above and further described herein, including components such as one or more processors 612 and memory 616 in communication via one or more buses 644 and a transceiver 602, which may operate in conjunction with a modem 240 and/or a communication component 242 for communication using dynamic FDM within a CC. For example, the communication component 242 can optionally include an MT unit 318 for communicating control information with one or more upstream nodes, a DU unit 320 for communicating with one or more downstream nodes, and/or a configuration component 642 for receiving one or more configurations indicating a combination of resource availability to be used in communicating with the upstream node(s) and/or downstream node(s).

In an aspect, the one or more processors 612 may include the modem 240 and/or may be part of the modem 240 using one or more modem processors. Accordingly, various functions related to the communication component 242 may be included in the modem 240 and/or the processor 612 and, in one aspect, may be performed by a single processor, while in other aspects, different ones of these functions may be performed by a combination of two or more different processors. For example, in an aspect, the one or more processors 612 may include any one or any combination of the following: a modem processor, or a baseband processor, or a digital signal processor, or a transmit processor, or a receiver processor, or a transceiver processor associated with transceiver 602. In other aspects, some of the features of the one or more processors 612 and/or modems 240 associated with the communication component 242 may be performed by the transceiver 602.

Further, the memory 616 may be configured to store local versions of the data and/or applications 675 used herein, or the communication component 242 and/or one or more sub-components thereof, executed by the at least one processor 612. The memory 616 may include any type of computer-readable medium usable by the computer or the at least one processor 612, such as Random Access Memory (RAM), read Only Memory (ROM), tape, magnetic disk, optical disk, volatile memory, non-volatile memory, and any combination thereof. In an aspect, for example, the memory 612 may be a non-transitory computer-readable storage medium storing one or more computer-executable code defining and/or data associated with the communication component 242 and/or one or more sub-components thereof while the IAB node 204 is operating the at least one processor 616 to execute the communication component 242 and/or one or more sub-components thereof.

The transceiver 602 may include at least one receiver 606 and at least one transmitter 608. Receiver 606 may include hardware, firmware, and/or software code executable by a processor for receiving data, including instructions, and stored in a memory (e.g., a computer-readable medium). Receiver 606 may be, for example, a Radio Frequency (RF) receiver. In an aspect, the receiver 606 may receive signals transmitted by an upstream node, a downstream node, or the like. Additionally, the receiver 606 may process such received signals and may also obtain measurements of the signals, such as, but not limited to, ec/Io, SNR, reference Signal Received Power (RSRP), received Signal Strength Indicator (RSSI), and the like. The transmitter 608 may include hardware, firmware, and/or software code executable by a processor for transmitting data, the code including instructions and being stored in a memory (e.g., a computer readable medium). Suitable examples of transmitter 608 may include, but are not limited to, an RF transmitter.

Further, in an aspect, the IAB node 204 may include an RF front end 688 that may be communicatively operable with the one or more antennas 665 and the transceiver 602 for receiving and transmitting radio transmissions, e.g., wireless communications transmitted by the at least one upstream node 202 or wireless transmissions transmitted by a UE or other downstream node. The RF front end 688 may be connected to one or more antennas 665 and may include one or more Low Noise Amplifiers (LNAs) 690, one or more switches 692, one or more Power Amplifiers (PAs) 698, and one or more filters 696 for transmitting and receiving RF signals.

In an aspect, the LNA 690 may amplify the received signal to a desired output level. In an aspect, each LNA 690 may have a specified minimum and maximum gain value. In an aspect, the RF front-end 688 may use one or more switches 692 to select a particular LNA 690 and its designated gain value based on a desired gain value for a particular application.

Further, for example, one or more PAs 698 may be used by the RF front end 688 to amplify signals to obtain RF output at a desired output power level. In an aspect, each PA 698 may have specified minimum and maximum gain values. In an aspect, the RF front end 688 may use one or more switches 692 to select a particular PA 698 and its specified gain value based on a desired gain value for a particular application.

Further, for example, one or more filters 696 may be used by the RF front end 688 to filter the received signal to obtain an input RF signal. Similarly, in an aspect, for example, a respective filter 696 may be used to filter the output from a respective PA 698 to produce an output signal for transmission. In an aspect, each filter 696 may be connected to a particular LNA 690 and/or PA 698. In an aspect, the RF front end 688 may use one or more switches 692 to select a transmit or receive path using a designated filter 696, LNA 690, and/or PA 698 based on a configuration as designated by the transceiver 602 and/or processor 612.

As such, transceiver 602 may be configured to transmit and receive wireless signals through one or more antennas 665 via RF front-end 688. In an aspect, transceiver 602 may be tuned to operate at a particular frequency such that IAB node 204 may communicate with, for example, one or more upstream nodes (e.g., base station 102, upstream IAB node, CU, DU, repeater, etc.) or one or more cells associated with one or more upstream nodes, one or more downstream nodes (e.g., UE 104, downstream IAB node, repeater, etc.), and so forth. In an aspect, for example, modem 240 may configure transceiver 602 to operate at a specified frequency and power level based on the configuration of IAB node 204 and the communication protocol used by modem 240.

In an aspect, modem 240 may be a multi-band-multi-mode modem that may process digital data and communicate with transceiver 602 to enable the use of transceiver 602 to transmit and receive digital data. In an aspect, modem 240 may be multi-band and configured to support multiple frequency bands for a particular communication protocol. In an aspect, modem 240 may be multi-mode and configured to support multiple operating networks and communication protocols. In an aspect, modem 240 may control one or more components of IAB node 204 (e.g., RF front end 688, transceiver 602) to enable transmission and/or reception of signals from a network or UE, upstream node, or downstream node based on a specified modem configuration. In an aspect, the modem configuration may be based on the mode of the modem and the frequency band used. In another aspect, the modem configuration may be based on configuration information associated with the IAB node 204, as provided by the network during cell selection and/or cell reselection or initial access.

In an aspect, the processor(s) 612 may correspond to one or more of the processors described in connection with the IAB node 204 in fig. 12. Similarly, the memory 616 may correspond to the memory described in connection with the IAB node 204 in fig. 12.

Referring to fig. 7, one example of an implementation of upstream node 202, which may include a gNB or other base station, an IAB donor, an IAB node, a CU, a DU, etc., and which may include various components, some of which have been described above, but also components such as one or more processors 712 in communication via one or more buses 744, and memory 716 and transceiver 702, etc., which may operate in conjunction with modem 244 to provide backhaul access to a core network. Additionally, one or more processors 712, as well as memory 716 and transceiver 702, etc., can optionally operate with scheduling component 246 to schedule an IAB node or other downstream node to communicate. In an example, scheduling component 26 can optionally include a configuration component 742 for configuring the IAB node to communicate with upstream node 202 and/or other upstream or downstream nodes.

The transceiver 702, receiver 706, transmitter 708, one or more processors 712, memory 716, applications 775, bus 744, RF front-end 788, LNA 790, switch 792, filter 796, PA 798, and one or more antennas 765 may be the same or similar to corresponding components of the IAB node 204 as described above, but configured or otherwise programmed for upstream node operation rather than IAB node operation.

In an aspect, the processor(s) 712 may correspond to one or more of the processors described in connection with the upstream node in fig. 12, as described. Similarly, memory 716 may correspond to the memory described in connection with the upstream node in fig. 12, as described.

Fig. 8 illustrates a flow chart of an example of a method 800 for configuring dynamic FDM resource allocation within a CC. Fig. 9 illustrates a flow chart of an example of a method 900 for utilizing dynamic FDM resource allocation within a CC. In an example, upstream node 202 may perform one or more functions described in method 800 using one or more components described in fig. 2 and 7. In an example, the IAB node 204 may perform one or more of the functions described in the method 900 using one or more of the components described in fig. 2 and 6. Methods 800 and 900 are described below in conjunction with one another to facilitate explanation of the associated functions and concepts. In at least one example, methods 800 and 900 need not be performed in conjunction with each other, and indeed one device may be configured to perform method 800 without having a corresponding device performing method 900, and vice versa.

In method 800, at block 802, a configuration for each of one or more cells of a downstream IAB node may be transmitted to the downstream IAB node, the configuration indicating a plurality of resource availability combinations, wherein each resource combination is over a plurality of time slots. In an aspect, configuration component 742 (e.g., in conjunction with processor(s) 712, memory 716, transceiver 702, scheduling component 246, etc.) can communicate a configuration for each of the one or more cells provided by downstream IAB node 204 to a downstream IAB node (e.g., IAB node 204), wherein the configuration can indicate a plurality of resource availability combinations, wherein each resource availability combination is over a plurality of time slots. For example, the configuration component 742 can communicate the configuration using RRC signaling, broadcast signaling, system information signaling, and the like. The configuration may indicate a number of resource availability combinations that may be indicated using the tables or constructs described above (e.g., a resource availability table, an availability combinelnation per cell table) or similar tables or constructs thereto. In one example, the node transmitting the configuration may be an IAB donor transmitting to a downstream IAB node, which may or may not be the last IAB node to receive the configuration that may originate at the IAB donor. In another example, if the node transmitting the configuration is not an IAB donor CU, the node may be the last hop of the relay node transmitting the configuration from the IAB donor CU to the downstream IAB node.

In method 900, at block 902, a configuration for each of one or more cells that may originate from an IAB donor may be received from an upstream node, the configuration indicating a plurality of resource availability combinations, wherein each resource combination is over a plurality of time slots. In an aspect, configuration component 642 (e.g., in conjunction with processor(s) 612, memory 616, transceiver 602, communication component 242, etc.) can receive a configuration from an upstream IAB node (e.g., upstream node 202) that can be originated by an IAB donor for each of one or more cells provided by IAB node 204, wherein the configuration can be indicative of a plurality of resource availability combinations, wherein each resource availability combination is over a plurality of time slots. For example, the configuration component 642 may receive the configuration from an upstream node in RRC signaling, broadcast signaling, system information signaling, and the like. In an example, if the upstream node is not itself an IAB donor CU, the upstream node may be the last hop of the relay node transmitting the configuration from the IAB donor CU to the IAB node 204.

In method 800, at block 804, DCI indicating one of the plurality of resource availability combinations for one or more cells may be transmitted to a downstream IAB node. In an aspect, configuration component 742 (e.g., in conjunction with processor(s) 712, memory 716, transceiver 702, scheduling component 246, etc.) can transmit DCI indicating one of a plurality of resource availability combinations for one or more cells to a downstream IAB node (e.g., IAB node 204). For example, the configuration component 742 may transmit the DCI in downlink control signaling (e.g., via PDCCH). In an example, the DCI may be DCI format 2_5 in the group shared PDCCH to indicate which resource availability combination is configured for which cells of the downstream IAB node 204.

In method 900, at block 904, DCI indicating one of the plurality of resource availability combinations for one or more cells may be received from an upstream node. In an aspect, configuration component 642 (e.g., in conjunction with processor(s) 612, memory 616, transceiver 602, communication component 242, etc.) can receive DCI from an upstream node (e.g., upstream node 202) indicating one of a plurality of resource availability combinations for one or more cells of IAB donor node 204. For example, the configuration component 642 may receive the DCI in downlink control signaling (e.g., via PDCCH). In an example, the DCI may be DCI format 2_5 in the group shared PDCCH to indicate which resource availability combination is configured for which cells of the downstream IAB node 204, as described above and further described herein.

In method 900, at block 906, communications may be conducted in one slot over one or more of the plurality of configured RB sets in symbols indicated as available by the one resource availability combination. In an aspect, MT unit 318 or DU unit 320 (e.g., in conjunction with processor(s) 612, memory 616, transceiver 602, communication component 242, etc.) may communicate in one slot over one or more of the plurality of configured RB sets in symbols indicated as available by the one resource availability combination. Thus, for example, the MT unit 318 or the DU unit 320 of the IAB node may use one or more RB sets indicated as available to communicate with one or more downstream or upstream nodes in one or more cells of the IAB node 204, as further described herein.

In one example, the configuration transmitted at block 802 or received at block 902 may indicate a plurality of resource availability combinations, which may be indicated using a table or construct described above (e.g., a resource availability table, an availability communication percell table) or similar table or construct thereto, as described above and further described herein. In one example, an item in the configuration may indicate resource availability for each resource availability combination of the one slot corresponding to all RB sets associated with a soft ("S") type, where the allocated resources may include resources in one or more RB sets, as described. For example, the configuration may include an availabilities combiners per cell table as described above and defined in 5G NR that indicates the respective resource availability combination index as a corresponding column of the table's row and slot index, with the value (item) in each row/column element indicating whether all RB sets associated with the soft type are available for use. As such, configuration component 642 may receive a resource allocation comprising one or more RB sets in one or more symbols indicated as S. In this example, configuration component 642 can determine whether it can communicate with upstream node 202 or one or more downstream nodes using the one or more sets of RBs in the one or more symbols based on the value.

For example, the same availability indication may be applied to all RB sets of each symbol type (e.g., DL/UL/flexible) in a slot. In this example, the resource availability table in TS 38.213 may be redefined, while the existing signaling related to DCI2_5 may remain unchanged. For example, the configuration component 742 may transmit or the configuration component 642 may receive a configuration as an availabilities combiners percell table indicating, for each of a plurality of resource availability combinations, one of the above-described values for each of a plurality of time slots. Configuration component 642 may then determine, for a given combination of resource availability (e.g., as indicated in DCI), whether a set of RBs of symbols indicated as S in a resource allocation from an upstream node are available for communication with upstream node 202 or one or more downstream nodes. Whether the RB set is available may be further based on whether the symbol indicated as S is an uplink symbol, a downlink symbol, or a flexible symbol, and whether the indication maps to a value in the modified resource availability table described above. In the event that configuration component 642 determines that RB sets are available, MT unit 318 unit may communicate with upstream node 202 on these RB sets based on symbol direction (uplink, downlink, or flexible), or DU unit 320 may communicate with one or more downstream nodes on these RB sets based on symbol direction.

Thus, in an example, when communicating over the one or more RB sets at block 906 (optionally at block 908), it may be determined that the one or more RB sets are associated with a soft type of a given symbol, and that the given symbol is a type of the slot indicated as being available based on the one resource availability combination. In an aspect, configuration component 642 (e.g., in conjunction with processor (S) 612, memory 616, transceiver 602, communication component 242, etc.) can determine that the one or more RB sets are associated with a soft ("S") type of a given symbol and that the given symbol is a type of the slot that is indicated as being available based on the one resource availability combination. For example, configuration component 642 may determine that one or more RB sets are associated with a soft type based on a resource configuration from an upstream node (e.g., as RB sets 544, 554 in fig. 5). Additionally, the configuration component 642 may determine that the given symbol is of a type in the slot that is indicated as being available based on the one combination of resource availability, which may include determining an indication related to a value indicated in the availabilities combinedspercell table for the one combination of resource availability for a slot index corresponding to the slot including the given symbol.

In another example, the same availability indication may be applied to a set of RBs selected for a symbol type (downlink, uplink, or flexible) of a slot. In this example, the configuration, DCI, or other signaling may be used to indicate the selected set of RBs. In one example, the selected set of RBs may be indicated using a bitmap, where each bit in the bitmap corresponds to one of the set of RBs previously RRC configured. In this example, configuration component 742 may transmit or configuration component 642 may receive RB configurations indicating configured RB sets, and the indication of the selected RB set may refer to the configured RB set in the RB configuration (e.g., by an index or other identifier). In another example, the selected RB set may be indicated using an RB set index value, where one of the previously configured RB sets may be selected.

In method 800, optionally at block 806, an indication of one or more selected RB sets of the plurality of configured RB sets may be transmitted to the downstream IAB node. In an aspect, configuration component 742 (e.g., in conjunction with processor(s) 712, memory 716, transceiver 702, scheduling component 246, etc.) can communicate an indication of one or more selected ones of the plurality of RB sets to a downstream IAB node (e.g., IAB node 204). For example, configuration component 742 may transmit an indication of the one or more selected RB sets in a Medium Access Control (MAC) -Control Element (CE), another DCI, additional control signaling to IAB node 204, or the like, as part of the configuration transmitted at block 802.

In method 900, optionally at block 910, an indication of one or more selected RB sets of a plurality of configured RB sets may be received from an upstream node. In an aspect, configuration component 642 (e.g., in conjunction with processor(s) 612, memory 616, transceiver 602, communication component 242, etc.) can receive an indication of one or more selected sets of RBs of a plurality of configured RBs from an upstream node (e.g., upstream node 202). For example, configuration component 642 may receive an indication of one or more selected sets of RBs in a Medium Access Control (MAC) -Control Element (CE), another DCI, additional control signaling from upstream node 202, etc., as part of the configuration received at block 902, as part of the DCI received at block 904.

For example, the indication may be signaled as a MAC-CE to indicate one or more selected or otherwise applicable RB sets per serving cell. In this example, the configuration component 642 may determine the selected set of RBs based on receiving the indication in the MAC-CE. In another example, the configuration transmitted at block 802 or received at block 902 may be extended to indicate the selected set of RBs. In a particular example, the availabilitycombiners percell table may be extended such that each row is associated with one or more selected or otherwise applicable RB sets. In this example, the one resource availability combination for a given cell may be indicated using existing DCI2_5, and the indicated resource availability combination may be associated with one or more selected RB sets in an RRC configured availabilities combinedspercell table. For example, one code point in DCI2_5 to availabilitycombinelntercell table (availability combination Id) may be both the availability pattern in the serving cell selection time domain and the associated applicable RB set. For example, the availability combination may have a format similar to the following:

The number of combinations of availability in the table may be extended (e.g., to over 512) to allow multiple selected RB sets for different combinations to be indicated. An example is shown in fig. 10.

Fig. 10 illustrates various configurations and DCI indications described herein, including a group common PDCCH 1000, an availabilities combiners cell table 1002, and a resource availabilities table 1004. In this example, the availabilitycombinesmalltable 1002 may be extended with a new column 1006 to indicate one or more selected RB sets to which the availability combination row (e.g., each Availability Indication (AI)) applies, and a per-slot value 1008 indicating the soft symbol availability status from the resourceaavailabilitytable 1004

In another specific example, the availabilities combinelnation cell table may be extended such that each row/column element may also indicate one or more selected or otherwise applicable RB sets (e.g., in addition to values mapped to the resourceability table). In this example, the existing DCI 2_5 may be maintained and the RRC-configured availabilities combiners percell table may be extended such that the resourceability element for each slot includes the following two indications: one is an existing 3-bit indication for selecting DL/UL/flexible symbols and the other is an indication for the set of RBs selected for the slot. For example, the availability combination received in RRC signaling may have a format similar to one or more of:

Where selected RBsets may be N-bit maps for selecting from among N RB sets.

Fig. 11 illustrates various configurations and DCI indications described herein, including a group shared PDCCH 1100 and an availabilitycombinelnation cell table 1102. In this example, an availabilities combineplacell table 1102 may be extended, wherein each resource availabilities value (such as resource availabilities value 1104) in the table 1102 includes a first indication (e.g., a first number of bits, such as 3 bits) indicating a selection of DL/U/flexible symbols and a second indication (e.g., a second number of bits) indicating a selection of RB sets, as described in the examples above.

In another example, the DCI transmitted at block 804 or received at block 904 may be extended to indicate the selected set of RBs. For example, DCI 2_5 may be extended with an additional new field to indicate one or more applicable RB sets. In one example, the DCI may include an availability indicator and an indicator of the selected RB set (e.g., an index of the applicable RB set) for each serving cell. In this example, one applicable RB set is indicated. In another example, the DCI may include a bitmap of the selected RB set and an availability indicator for each serving cell. In this format, a plurality of RB sets having bit=1 may be applicable. In addition, for example, the maximum number of availability indicators in the DCI may be extended (e.g., to over 128) to allow a respective set of RBs per availability indicator to be configured for the one or more cells of the IAB node.

In yet another example, a new DCI format may be used or defined to indicate one or more applicable RB sets per serving cell. In this example, the indication transmitted at block 906 or received at block 910 may include the new DCI format, which may indicate an index of the selected RB set or a bitmap of one or more selected RB sets.

In either case, based on receiving an indication of the selected RB set (whether by extended RRC configuration, extended DCI, or new MAC-CE or DCI), configuration component 642 may determine whether the RB sets indicated as soft ("S") for a given set of one or more symbols may be used based on determining whether the selected RB set is the selected RB set and/or whether the selected RB set is indicated as available for this one resource availability combination by other configurations (e.g., RRC configurations) and/or DCI selections (as described herein). With the selected set of RBs indicated as available, MT unit 318 may communicate with one or more upstream nodes accordingly, or DU unit 320 may communicate with one or more downstream nodes accordingly.

In another example, the configuration transmitted at block 802 or received at block 902 may be such that each entry in each resource availability combination indicates resource availability for each of a plurality of configured RB sets of one slot. For example, separate availability indications may be applied for different RB sets for symbol types (downlink, uplink, flexible) of the slot. This can be used in the case where the time domain resource pattern of H/S/NA is configured per RB set in the frequency domain. In one example, the existing DCI 2_5 may be maintained and the RRC-configured resource availability table (e.g., transmitted at block 802 or received at block 902) may be extended such that these values may indicate not only the range of 0 … 7, but also the value of each given RB set. For example, for L RB sets, the resource availability table may include the range 0 … 2 ^3*L -a value of 1 value. In this regard, the availabilities combineperformance table may be extended to accept a larger range of values, and each value may represent not only an indication from the above-described resourceability table, but also the value of one or more RB sets. For example, canThe usability combinations may have a format similar to the following:

in another example, the existing DCI 2_5 may be maintained and an RRC-configured availabilitycombinepartell table (e.g., transmitted at block 802 or received at block 902) may be extended such that each row in the table may indicate a respective (RB set i, slot j). In an example, the arrangement of RB sets and slots in each row may be indicated in a wireless communication specification such that the IAB node 204 may be configured with the arrangement in the memory 216. In an example, each row in availabilities coding (availability combination) may be arranged in RB set-after-slot as follows: (RB set 1_slot 1, RB set 2_slot 1, …, RB set m_slot 1, RB set 1_slot 2, … RB set m_slot 2 … RB set 1_slot N, … RB set m_slot N). In another example, each row in availabilitycoding may be arranged as a set of RBs after time slots as follows: (time slot 1_rb set 1, time slot 2_rb set 1, … time slot n_rb set 1, time slot 2_rb set 2, … time slot n_rb set 2, … time slot 1_rb set M, … time slot n_rb set M). In an example, the maximum number of resource availability combinations (e.g., to more than 256) may be extended to account for additional combinations of each RB set.

In yet another example, DCI 2_5 (e.g., transmitted at block 804 or received at block 904) may be extended from an indication per cell to an indication per RB set per cell, and RRC-configured availabilities combiners cells may be extended such that different subsets of the rows in availabilities combiners are associated with different RB sets of the serving cell. For example, DCI 2_5 may indicate the availability indication and RB set 1_cell 1, the availability indication and RB set 2_cell 1, … availability indication and RB set m_cell 1, the availability indication and RB set 1_cell 2, … AI RB set m_cell 2, …. In another example, in availabilitycodes, row 1:l1 may be associated with RB set 1; rows L1+1:L2 may be associated with RB set 2, …. In these examples, the maximum availability indication DCI payload size may be extended (e.g., to more than 128) to allow additional availability indications per RB set. In addition, for example, the maximum number of availability combinations may be extended (e.g., to over 512) to accommodate the additional value range.

In yet another example, DCI 2_5 (e.g., transmitted at block 804 or received at block 904) may be extended from an indication per cell to an indication per RB set per cell, and availabilitycombiners per cell (e.g., transmitted at block 804 or received at block 904) may be extended from per cell to per RB set per cell, or new parameters may be introduced. For example, a new parameter availabilities combinessper rbsetper cell (combination of availability per RB set per cell) may be introduced, or availabilities combinessper cell may be redefined as per RB set per cell, where a new field "RBset identity" may be added. In this example, the maximum availability may be increased to indicate DCI payload size (e.g., to over 128) to account for a greater number of combinations indicated in the DCI.

In yet another example, multiple DCIs may be configured, each DCI associated with one or more RB sets per cell, and/or each DCI configured with its own RNTI and/or search space. In an example, in method 800, optionally at block 808, a second DCI indicating one or more other RB sets per serving cell may be transmitted to a downstream IAB node. In an aspect, configuration component 742 (e.g., in conjunction with processor(s) 712, memory 716, transceiver 702, scheduling component 246, etc.) can transmit a second DCI indicating one or more other RB sets per serving cell to a downstream IAB node (e.g., IAB node 204). For example, configuration component 742 may transmit DCI at block 804 and also transmit a second DCI (or one or more other DCIs) at block 808, where each DCI may correspond to one or more RB sets.

In method 900, optionally at block 912, a second DCI may be received from the upstream node indicating one or more other sets of RBs per serving cell. In an aspect, configuration component 642 (e.g., in conjunction with processor(s) 612, memory 616, transceiver 602, communication component 242, etc.) can receive a second DCI indicating one or more other RB sets per serving cell from an upstream node (e.g., upstream node 202). For example, configuration component 642 may receive DCI at block 904 and a second DCI (or one or more other DCIs) at block 912, where each DCI may correspond to one or more RB sets. Thus, for example, configuration component 642 may determine the one resource availability combination indicated for a given set of RBs from DCI associated with the set of RBs.

In either case, based on the determined RB set and the configuration or DCI(s) (which may be extended as described above), configuration component 642 may determine the one resource availability combination associated with the RB set. In an example, configuration component 62 may determine whether the RB set (S) may be used based on determining that the indicated resource availability combination for the RB set (S) indicated as soft ("S") may be available to the one resource availability combination through other configurations (e.g., RRC configurations) and/or DCI selections (as described herein). With the RB set(s) indicated as available, MT unit 318 may communicate with one or more upstream nodes accordingly, or DU unit 320 may communicate with one or more downstream nodes accordingly.

In yet another example, the number of slots indicated in the availabilitycombiners percell table may not be equal to or greater than the PDCCH monitoring periodicity of DCI format 2_5 as provided by the defined SearchSpace. This may allow the PDCCH of less than DCI format 2_5 to monitor the number of periodic slots and may allow defining default behavior for non-indicated slots (e.g., using implicit determination). The resource availability indication per combination may be only on the slots containing soft symbols. Slots without soft symbols may be skipped in the configuration of the resourceaavailability table.

Fig. 12 is a block diagram of a MIMO communication system 1200 including an upstream node 202 and an IAB node 204 (or MT units, UEs or other downstream nodes thereof). MIMO communication system 1200 may illustrate aspects of wireless communication access network 100 described with reference to fig. 1. The upstream node 202 may be an example of aspects of the upstream node 202 described with reference to fig. 2-5. Upstream node 202 may be equipped with antennas 1234 and 1235 and IAB node 204 may be equipped with antennas 1252 and 1253. In MIMO communication system 1200, upstream node 202 may be capable of transmitting data on multiple communication links simultaneously. Each communication link may be referred to as a "layer," and a "rank" of the communication link may indicate the number of layers used for communication. For example, in a 2x2 MIMO communication system in which the upstream node 202 transmits two "layers," the rank of the communication link between the upstream node 202 and the IAB node 204 is 2.

At upstream node 202, a transmit (Tx) processor 1220 may receive data from a data source. The transmit processor 1220 may process the data. Transmit processor 1220 may also generate control symbols or reference symbols. Transmit MIMO processor 1230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, or reference symbols, if applicable, and may provide output symbol streams to transmit modulators/demodulators 1232 and 1233. Each modulator/demodulator 1232-1233 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain a stream of output samples. Each modulator/demodulator 1232-1233 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a DL signal. In one example, DL signals from modulators/demodulators 1232 and 1233 may be transmitted via antennas 1234 and 1235, respectively.

The IAB node 204 may be an example of aspects of the IAB node 204 described with reference to fig. 1-3, etc. At the IAB node 204, antennas 1252 and 1253 may receive the DL signal from the upstream node 202 and may provide received signals to modulators/demodulators 1254 and 1255, respectively. Each modulator/demodulator 1254 through 1255 may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each modulator/demodulator 1254 through 1255 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 1256 may obtain the received symbols from modulators/demodulators 1254 and 1255, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive (Rx) processor 1258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data to an IAB node 204 to a data output, and provide decoded control information to a processor 1280 or a memory 1282.

Processor 1280 may execute stored instructions in some cases to instantiate communication component 242 (see, e.g., fig. 2 and 6) for providing IAB node functionality.

On the Uplink (UL), at the IAB node 204, a transmit processor 1264 may receive and process data from a data source. The transmit processor 1264 may also generate reference symbols for a reference signal. Symbols from transmit processor 1264 may be precoded by transmit MIMO processor 1266, if applicable, further processed by modulators/demodulators 1254 and 1255 (e.g., for SC-FDMA, etc.), and transmitted to upstream node 202 according to communication parameters received from upstream node 202. At upstream node 202, the UL signal from IAB node 204 may be received by antennas 1234 and 1235, processed by modulators/demodulators 1232 and 1233, detected by a MIMO detector 1236 if applicable, and further processed by a receive processor 1238. Receive processor 1238 may provide decoded data to a data output and processor 1240 or memory 1242.

Processor 1240 may, in some cases, execute the stored instructions to instantiate scheduling component 246 (see, e.g., fig. 2 and 7) for configuring the IAB node to provide IAB node functionality.

The components of the IAB node 204 may be implemented individually or in whole with one or more ASICs adapted to perform some or all of the applicable functions in hardware. Each of the mentioned modules may be means for performing one or more functions related to the operation of the MIMO communication system 1200. Similarly, the components of upstream node 202 may be implemented individually or in whole using one or more ASICs adapted to perform some or all of the applicable functions in hardware. Each of the mentioned components may be means for performing one or more functions related to the operation of the MIMO communication system 1200.
