Description
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This patent application claims priority to U.S. non-provisional patent application No. 17 / 821,119, filed on August 19, 2022, entitled “MAPPING OF TIME AND FREQUENCY RESOURCES TO BEAMS OF A NETWORK NODE,” which is hereby expressly incorporated herein by reference. Technical Field
[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for mapping of time and frequency resources to beams of network nodes. Background Art
[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).
[0005] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).
[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by: improving spectrum efficiency; reducing costs; improving services; utilizing new spectrum; and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink to better integrate with other open standards; and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0030] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.
[0031] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0032] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).
[0033] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). For another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).
[0034] In some examples, the network node 110 is or includes a network node (such as an RU) that communicates with the UE 120 via a radio access link. In some examples, the network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, the network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks, using any suitable transport network.
[0035] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown in , network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).
[0036] In some aspects, the term "base station" or "network node" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with the network node 110). In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions, but not another base station function. Thus, a single device may include more than one base station.
[0037] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.
[0038] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).
[0039] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.
[0040] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station and / or a subscriber unit. UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node and / or any other suitable device configured to communicate via a wireless or wired medium.
[0041] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0042] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.
[0043] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.
[0044] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).
[0045] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz–24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.
[0046] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.
[0047] In some aspects, the network node may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may receive an indication of a mapping of time and frequency resources to a set of beams for the network node from a parent network node; receive one or more communications from the parent network node to be forwarded via the set of beams using the set of time and frequency resources; and forward the one or more communications via one or more beams in the set of beams based at least in part on the one or more communications being associated with the set of time and frequency resources, the set of time and frequency resources being mapped to the one or more beams according to the mapping of the time and frequency resources to the set of beams for the network node. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0048] In some aspects, the parent network node may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send an indication of a mapping of time and frequency resources to a set of beams of a network node; and send one or more communications from the parent network node to be forwarded via the set of beams using the set of time and frequency resources, the one or more communications being associated with the set of time and frequency resources mapped to one or more beams. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0049] In some aspects, the UE may include a communication manager 140. As described in greater detail elsewhere herein, the communication manager 140 may receive an indication of a configuration for mapping time and frequency resources to a beam that provides a connection between the UE and a network node; receive one or more communications via resources within the time and frequency resources mapped to the beam; and enter a low power mode outside of the time and frequency resources mapped to the beam. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0050] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The content described is different.
[0051] Figure 22 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.
[0052] At network node 110, transmit processor 220 may receive data intended for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 may select one or more modulation and coding schemes (MCS) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120, and may provide data symbols for UE 120. Transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 234t).
[0053] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.
[0054] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.
[0055] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.
[0056] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, reference Figures 5 to 11 ) or any aspect of any of the methods described herein.
[0057] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 5 to 11 ) or any aspect of any of the methods described herein.
[0058] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the UE 120 may perform one or more techniques associated with mapping of time and frequency resources to beams of the network node as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 8 The process of 800 Fig. 9 900 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of network node 110 and / or UE 120, may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 8 The process of 800 Fig. 9 The process 900 and / or operations of other processes described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.
[0059] In some aspects, the network node includes means for receiving an indication of a mapping of time and frequency resources to a set of beams for the network node from a parent network node (e.g., using antenna 234, modem 232, MIMO detector 236, receive processor 238, controller / processor 240, or memory 242, etc.); means for receiving one or more communications from the parent network node (e.g., using antenna 234, modem 232, MIMO detector 236, receive processor 238, controller / processor 240, or memory 242, etc.) to be forwarded via the set of beams using the set of time and frequency resources; and / or means for forwarding the one or more communications via one or more beams in the set of beams (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, or memory 242, etc.) based at least in part on the one or more communications being associated with the set of time and frequency resources to which the one or more beams are mapped according to the mapping of the time and frequency resources to the set of beams for the network node. In some aspects, components for the network node to perform operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.
[0060] In some aspects, the parent network node includes means for sending an indication of a mapping of time and frequency resources to a set of beams of the network node (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, or the memory 242, etc.); and / or means for sending one or more communications from the parent network node (e.g., using the antenna 234, the modem 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, or the memory 242, etc.) to be forwarded via the set of beams using the set of time and frequency resources, the one or more communications being associated with the set of time and frequency resources mapped to the one or more beams. In some aspects, means for the parent network node to perform operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.
[0061] Although Figure 2The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.
[0062] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The content described is different.
[0063] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also called an independent base station or a monolithic base station) or a decomposed base station. A "network entity" or a "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).
[0064] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.
[0065] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.
[0066] Figure 3 3 is a diagram illustrating an example decomposed base station architecture 300 according to the present disclosure. The decomposed base station architecture 300 may include a CU 310, which may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed control units (such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.
[0067] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium, or both.
[0068] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.
[0069] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partitioning (such as that defined by 3GPP). In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.
[0070] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions, or low PHY layer functions (such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc.) based on functional splitting (e.g., functional splitting defined by 3GPP). In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.
[0071] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 335) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.
[0072] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.
[0073] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).
[0074] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The content described is different.
[0075] Figure 4 is a diagram illustrating an example 400 network node providing connectivity between a parent network node and one or more UEs according to the present disclosure.
[0076] like Figure 4 As shown, the parent network node and the network node may communicate via communication link 405. For example, the network node may operate as a relay node or forwarding node for the parent network node.
[0077] Also like Figure 4 As shown, the network node can communicate with the first UE and the second UE via communication link 410. The network node can use a single omni-directional beam or a single wide-angle beam, and all connected UEs can communicate with the network node through the omni-directional beam or the wide-angle beam (for example, communicate with the parent network node via the network node).
[0078] In some networks (e.g., NR networks and sub-THz band networks), line-of-sight (LOS) channels may be preferred or necessary for coverage and high throughput. In some environments, such as indoor or urban environments, LOS channels may not be available or difficult to determine. For this reason, some network deployments may rely on network nodes to perform functions such as repeaters, relays, femtocells, and / or reconfigurable smart surfaces (RIS) to penetrate windows or other materials or bypass obstacles.
[0079] The network node may be required to use low-latency relays so that the UE channel delay spread can pass the cyclic prefix (CP) length (to avoid inter-symbol interference (ISI)), cover a spatial area (e.g., a room), and support communications to multiple UEs, etc. In order for the network node to meet network requirements, the relay may deploy a transparent beam management procedure (TBMP).
[0080] In order to use TBMP, the network node may need to not perform digital processing on the data or synchronization signal blocks (SSBs) based at least in part on relay low latency requirements (e.g., latency less than the CP length). This can reduce ISI from signals that arrive at the UE in a path that does not include the network node. Based at least in part on the network node not performing digital processing on the data or SSB and not knowing the UE associated with the data or SSB, the network node uses the single omnidirectional beam or the single wide-angle beam so that the UE can receive the data or SSB. However, based at least in part on the use of the single omnidirectional beam or the single wide-angle beam, the network node does not achieve the beamforming gain that would have been achieved using beamforming toward the UE. As such, the network node's communication with the UE may be accompanied by increased error rates and / or reduced spectral efficiency (e.g., reduced MCS, increased repetitions, and / or increased FEC rate, etc. As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The content described is different.
[0081] In some aspects described herein, the parent node may define UE grouping signaling for beam control with improved optimization. For example, the UE may be grouped based at least in part on the beams through which the UE passes through the network node and through which it is connected to the parent network node. The parent network node may map resources (e.g., time and frequency resources) to a beam set of the network node. For example, the parent network node may allocate a certain amount of resources to the beam based at least in part on the number of UEs connected through the beams in the beam set and / or the amount of data communicated via the beam. When the parent network node provides the network node with a communication for forwarding, the network node may forward the communication using a beam (mapped to the resources allocated for the communication). In this way, the network node can communicate with the UE using a beam with improved beamforming gain and coverage without having to perform digital processing on the communication to determine the beam for forwarding the communication. This can reduce error rates and / or increase spectral efficiency (e.g., increase MCS, reduce repetition and / or reduce FEC rate, etc.) to save communication, power, computing and / or network resources that would otherwise be used to communicate via omni-directional beams or wide-angle beams. Additionally or alternatively, using the mapping of resources to the beam set can support improved spatial separation, which can reduce ISI.
[0082] In some aspects, the parent network node may provide a mapping of resources to the set of beams before providing communications for forwarding. In this way, the network node may know in advance which direction the network node is to steer communications (e.g., physical downlink shared channel (PDSCH) and / or SSB) without requiring processing or associated delays.
[0083] In some aspects, the network node may perform transparent beam management in which the UE is unaware of the network node and / or a beam used to communicate with the parent network node is directed to the network node for forwarding (e.g., transparent to the UE). In some aspects, the network node may provide an indication of a mapping to support the UE to enter a low power mode during a time not allocated to a beam or on a frequency bandwidth not allocated to a beam on which the UE communicates with the parent network node and / or the network node.
[0084] In some aspects, the network node may report (e.g., to a parent network node) a capability to relay signals with very low latency relative to the CP length, a capability to transmit multiple beams simultaneously, and / or a number of beams that the network node may transmit simultaneously (e.g., for frequency division multiplexed beams). Additionally or alternatively, the network node may indicate a maximum number of beams that the network node may receive and / or transmit based at least in part on, for example, hardware limitations and / or coverage limitations (e.g., the size of a room or area covered by the network node), etc. The network node may indicate whether the network node supports beam-to-resource mapping (e.g., UE grouping) for PDSCH communications and / or for physical uplink shared channel (PUSCH) communications.
[0085] The parent network node may inform the network node of the mapping for the SSB. The parent node may send multiple SSBs in the direction of the repeater for forwarding. The SSBs may be relayed to different spatial directions to cover the area of the network node. Once a UE is connected to a beam in a network node beam (e.g., associated with an SSB), the network node may be configured to use the beam to send and / or receive communications. For example, if there is only one connected UE, the network node may direct communications (e.g., PDSCH and / or PUSCH) via the beam only in the direction of the connected UE.
[0086] If there is more than one connected UE, the parent network node may configure the mapping for the network node. The parent network node may indicate to the network node whether to use frequency separation (e.g., frequency division multiplexing (FDM)) or time separation (e.g., time division multiplexing (TDM)) between beams of the network node. Additionally or alternatively, the parent network node may indicate one or more parameters for FDM or TDM, such as separation size and / or periodicity of each set of time and frequency resources allocated to each beam (e.g., associated with each UE group to which each beam is connected). The parent network node may indicate whether the resource-beam mapping is to be used for PDSCH communication and / or PUSCH communication. In some aspects, the parent network node may send one or more of these indications via periodic or aperiodic communication using RRC communication and / or medium access control (MAC) control elements (CEs).
[0087] In some aspects, the parent network node may notify the connected UEs of a mapping (e.g., based at least in part on a grouping of UEs associated with different resources configured for a beam connected to the parent network node via the network node) so that the connected UEs can utilize reduced open RF (e.g., during time allocated to different beams) or reduced bandwidth (e.g., on frequencies allocated to different beams) to reduce power consumption.
[0088] The network node will follow the configuration from the parent network node and relay the parent network node beam to beam. The parent network node may update the configuration of the mapping (e.g., a change in the amount of resources allocated to each beam) based at least in part on a change in the number of connected UEs and / or the beams used to communicate with the connected UEs, etc.
[0089] Figure 5 is a diagram of an example 500 associated with mapping of time and frequency resources to beams of a network node according to the present disclosure. Figure 5 As shown, a network node (e.g., network node 110, IAB node, relay, forwarding node, relay, DU, and / or RU) may communicate with a parent network node (e.g., network node 110, IAB node, relay, forwarding node, relay, CU, DU, and / or RU) and one or more UEs (e.g., UE 120). In some aspects, the network node, the parent network node, and / or the one or more UEs may be part of a wireless network (e.g., wireless network 100). The network node, the parent network node, and / or the one or more UEs may be in a Figure 5 The operations shown are performed after a wireless connection has been established.
[0090] As indicated by reference numeral 505, the parent network node may send configuration information, and the network node may receive configuration information. In some aspects, the network node may receive the configuration information via one or more of RRC signaling, one or more MAC CEs, and / or downlink control information (DCI), etc. In some aspects, the configuration information may include an indication of one or more configuration parameters for selection by the network node (e.g., known to the network node and / or previously indicated by the parent network node or other network device) and / or explicit configuration information for the network node to use to configure the network node, etc.
[0091] In some aspects, the configuration information may indicate that the network node is to send an indication of support for mapping time and frequency resources to beams. In some aspects, the configuration information may indicate that the network node is to send an indication of one or more parameters supported for mapping time and frequency resources to beams. For example, the configuration information may indicate that the network node is to send an indication of support for TDM and / or FDM for mapping.
[0092] The network node may configure itself based at least in part on the configuration information.In some aspects, the network node may be configured to perform one or more operations described herein based at least in part on the configuration information.
[0093] As shown by reference numeral 510, the network node may send an indication of support for mapping time and frequency resources to beams, and the parent network node may receive an indication of support for mapping time and frequency resources to beams. In some aspects, the indication of support may indicate support for one or more parameters for mapping time and frequency resources to beams. For example, the indication of support may include an indication of support for frequency division multiplexing communications via a first beam and a second beam (e.g., in the set of beams), a maximum number of beams that may be included (e.g., supported for inclusion) in the set of beams, a mapping of time and frequency resources for downlink communications to the set of beams of the network node (e.g., the indication of support may indicate the ability of the network node to map specific resources to different beams, such as the ability of the network node to map communications received on a first set of resources to a first beam so that the network node forwards the communications via the first beam while mapping communications received on a second set of resources to a second beam, etc.), and / or a mapping of time and frequency resources for uplink communications to the set of beams of the network node, etc.
[0094] In some aspects, the network node may indicate support for mapping communications received (e.g., for forwarding) on a first set of resources to forwarding via a first beam and mapping communications received (e.g., for forwarding) on a second set of resources to forwarding via a second beam.
[0095] As indicated by reference numeral 515, the network node may receive a reference signal to forward via the set of beams of the network node, and the parent network node may send a reference signal to forward via the set of beams of the network node. In some aspects, the reference signal may include an SSB and / or a channel state information reference signal (CSI-RS). The reference signal may be associated with establishing a connection with the parent network node via the network node and / or beam management (e.g., beam selection and / or reselection), etc.
[0096] The network node may forward the reference signal to one or more UEs via the set of beams, as indicated by reference numeral 520. In some aspects, the network node may forward the reference signal without requiring digital processing, deep packet inspection, or other processes for detecting within a packet carrying the reference signal an indication of a beam associated with the reference signal.
[0097] As indicated by reference numeral 525, the network node may receive one or more communications based at least in part on the reference signal, and the one or more UEs may send one or more communications based at least in part on the reference signal. For example, the network node may receive one or more random access channel communications and / or measurement reports associated with the reference signal. The reference signal may include an SSB and / or a CSI-RS, among others.
[0098] As indicated by reference numeral 530, the network node may forward one or more communications based at least in part on the reference signal, and the parent network node may receive one or more communications based at least in part on the reference signal. In some aspects, the one or more communications may indicate (e.g., using an SSB identifier) an SSB having a highest signal strength as measured by the UE. The parent network node may determine that the UE is in a position associated with communicating with the parent network node via the beam associated with the SSB.
[0099] The network node may provide a connection between the parent network node and the one or more UEs via one or more beams in the beam set based at least in part on the reference signal. For example, the UE may communicate data, reference signals, and / or feedback between the parent network node and the one or more UEs via the one or more beams covering the location of the one or more UEs.
[0100] As shown by reference numeral 535, the parent network node may identify the number of UEs and / or data per beam. In some aspects, the parent network node may determine the number of UEs and / or data per beam based at least in part on communication (based at least in part on the reference signal). In some aspects, the parent network node may allocate a portion of resources (time and frequency resources) based at least in part on the number of UEs and / or data on the corresponding beam. For example, if two UEs are connected via a first beam and one UE is connected via a second beam, the parent network node may allocate more resources to the first beam than to the second beam (e.g., 2 / 3 of the resources are allocated to the first beam and 1 / 3 of the resources are allocated to the second beam).
[0101] In some aspects, a beam in the set of beams has no connected UE. The parent network node may not allocate time and frequency resources for forwarding communications via the beam.
[0102] In some aspects, a first subset of the set of time and frequency resources associated with a first beam is time-division multiplexed with a second subset of the set of time and frequency resources associated with a second beam. For example, resources within a first time period are mapped to the first beam, and resources within a second time period are mapped to the second beam. The first time period and the second time period may alternate and / or repeat. In some aspects, a first subset of the set of time and frequency resources associated with a first beam is frequency-division multiplexed with a second subset of the set of time and frequency resources associated with a second beam. For example, resources within a first bandwidth (e.g., frequency cells, bandwidth portions, and / or another type of frequency resources) are mapped to the first beam, and resources within a second bandwidth are mapped to the second beam.
[0103] As indicated by reference numeral 540, the network node may receive an indication of a configuration for mapping of time and frequency resources to the set of beams of the network node, and the parent network node may send an indication of a configuration for mapping of time and frequency resources to the set of beams of the network node. For example, the network node may receive an indication of a mapping of time and frequency resources to the set of beams of the network. In some aspects, the mapping may allocate different amounts of resources to different beams in the set of beams. For example, a beam on which the network node does not have a connected UE (e.g., as determined at least in part based on communications received at least in part based on the reference signal) may not have resources allocated for data communications and / or may still have resources allocated for subsequent reference signals (e.g., SSBs).
[0104] In some aspects, the configuration for mapping time and frequency resources to the set of beams may indicate parameters such as whether to use one or more of TDM of the one or more beams or FDM of the one or more beams, whether to use the mapping of time and frequency resources to the set of beams of the network node for uplink data channels and / or whether to use the mapping of time and frequency resources to the set of beams of the network node for downlink data channels, etc. Additionally or alternatively, the parameters may include a time slot for TDM of the one or more beams and / or a frequency slot for FDM of the one or more beams, etc.
[0105] As indicated by reference numeral 545, the network node may send an indication of the configuration for mapping, and the UE may receive the indication of the configuration for mapping. In some aspects, the network node may forward an indication of a schedule of a subset of the set of time and frequency resources mapped to a beam through which the UE is connected to the network node and the parent network node. The UE may reduce power consumption by utilizing reduced open RF or reduced bandwidth based at least in part on the schedule of the subset of the set of time and frequency resources mapped to the beam.
[0106] As shown by reference numeral 550, the network node may receive one or more communications to forward using the set of time and frequency resources, and the parent network node may send one or more communications to forward using the set of time and frequency resources. In some aspects, the network node may receive one or more communications to forward via the set of beams using the set of time and frequency resources.
[0107] The network node may forward the one or more communications via one or more beams and / or receive additional communications based at least in part on the association with the set of time and frequency resources, as indicated by reference numeral 555. In some aspects, the network node may forward the one or more communications via one or more beams in the set of beams based at least in part on the association of the one or more communications with the set of time and frequency resources, the set of time and frequency resources being mapped to the one or more beams according to a mapping of the time and frequency resources to the set of beams of the network node.
[0108] In some aspects, the set of one or more communications includes: a first communication directed to a first UE via a beam in the one or more beams and a second communication directed to a second UE via the beam in the one or more beams. In some aspects, forwarding the one or more communications via the one or more beams in the set of beams includes: forwarding the first communication via a first subset of the set of time and frequency resources, and forwarding the second communication via a second subset of the set of time and frequency resources, the first subset being associated with the beam, the second subset being associated with the beam and different from the first subset.
[0109] In some aspects, the network node may receive a set of uplink communications via the one or more beams, via time and frequency resources mapped to the one or more beams. For example, the configuration for mapping time and frequency resources to the set of beams of the network node may indicate a mapping of time and frequency resources for uplink communications and / or downlink communications. In this way, the network node may use a receive beam to receive communications from a UE at a time and / or frequency assigned to the receive beam.
[0110] As indicated by reference numeral 560, the network node may send an indication of an update to support mapping of time and frequency resources to beams, and the parent network node may receive an indication of an update to support mapping of time and frequency resources to beams.
[0111] As indicated by reference numeral 565, the network node and the parent network node may communicate an indication of an update to the mapping of time and frequency resources to the set of beams. In some aspects, the parent network node may send the indication of an update to the mapping. In some aspects, the network node may send an indication of an update associated with the mapping. For example, the network node may send an indication of an update to the number of beams supported for the set of beams, support for mapping of time and frequency resources for downlink communications to the set of beams of the network node, or support for mapping of time and frequency resources for uplink communications to the set of beams of the network node, etc.
[0112] In some aspects, the updating of the mapping of time and frequency resources is based at least in part on: the amount of data communicated via the corresponding beam or the number of UEs connected via the corresponding beam. For example, the updating may be based at least in part on one or more UEs moving from one beam of the network node to another beam or one or more UEs moving out of coverage of the network node.
[0113] Based at least in part on mapping resources to beams of the network node, the network node can communicate with the UE using beams with improved beamforming gain and coverage without having to perform digital processing on the communication to determine the beam used to forward the communication. This can reduce error rates and / or increase spectral efficiency (e.g., increase MCS, reduce repetition and / or reduce FEC rate, etc.) to save communication, power, computation and / or network resources that would otherwise be used to communicate via omni-directional beams or wide-angle beams. Additionally or alternatively, using the mapping of resources to the set of beams can support improved spatial separation, which can reduce ISI.
[0114] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The content described is different.
[0115] Figure 6 6 is a diagram of an example 600 associated with mapping of time and frequency resources to beams of a network node according to the present disclosure. Figure 6 As shown, a network node (e.g., network node 110, IAB node, relay, forwarding node, relay, DU, and / or RU) may communicate with a parent network node (e.g., network node 110, IAB node, relay, forwarding node, relay, CU, DU, and / or RU) and one or more UEs (e.g., UE 120). In some aspects, the network node, the parent network node, and / or the one or more UEs may be part of a wireless network (e.g., wireless network 100). The network node, the parent network node, and / or the one or more UEs may be in a Figure 6 The operations shown are performed after a wireless connection has been established.
[0116] like Figure 6 As shown, the parent network node and the network node may communicate via communication link 605. In some aspects, the network node may operate as a relay node or forwarding node for the parent network node.
[0117] Also like Figure 6As shown, the network node may communicate with a first UE via a communication link associated with beam 610A. The network node may not have a connected UE using beams 610B or 610C. The network node may communicate with a second UE and a third UE via beam 610D.
[0118] In some aspects, the network node may indicate to the parent network node that one UE is connected via beam 610A, two UEs are connected via beam 610D, and no UEs are connected via beams 610B or 610C. In some aspects, the network node may provide the indication based at least in part on forwarding measurements of beams 610A through 610D from the UEs. In this way, the parent network node may determine that the beam associated with the first reference signal (e.g., beam 610A) should be allocated with time and frequency resources for communicating a data channel with the first UE, and that the beam associated with the second reference signal (e.g., beam 610D) should be allocated with time and frequency resources for communicating a data channel with the second UE and the third UE.
[0119] In some aspects, the parent network node may determine the amount of resources to be allocated per beam based at least in part on the number of UEs connected per beam and / or the amount of data communicated per beam. Additionally or alternatively, the parent network node may determine the amount of resources to be allocated based at least in part on the type of data communicated per beam. In some aspects, the parent network node may determine the mapping type (e.g., TDM-based or FDM-based) based at least in part on the type of data communicated per beam. For example, if the first UE is receiving a data stream, the parent network node may use FDM to provide mapping resources for beam 610A without time constraints. In some aspects, the mapping type is based at least in part on the capabilities of the network node.
[0120] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The content described is different.
[0121] Figure 7 700 and 705 are diagrams of examples associated with mapping of time and frequency resources to beams of network nodes according to the present disclosure. Figure 7 As shown, a network node (e.g., network node 110, IAB node, relay, forwarding node, relay, DU, and / or RU) may communicate with a parent network node (e.g., network node 110, IAB node, relay, forwarding node, relay, CU, DU, and / or RU) and one or more UEs (e.g., UE 120). In some aspects, the network node, the parent network node, and / or the one or more UEs may be part of a wireless network (e.g., wireless network 100). The network node, the parent network node, and / or the one or more UEs may be in a Figure 7 The operations shown are performed after a wireless connection has been established.
[0122] As shown in example 700, the parent network node may map resources to beam 610D and beam 610A based at least in part on the UEs that beams 610D and 610A have connections. In a first time period, the parent network node may allocate resources to two second UE communications (e.g., communications with the first UE) and one third UE communication. In some aspects, some resources mapped to beam 610D and beam 610A may not be allocated to communications. In a second time period, the parent network node may allocate resources to the first UE communication.
[0123] The first time period and the second time period may be repeatedly alternated for a period of time or multiple times. In this way, the network node may forward communications via only one beam at a time.
[0124] As shown in example 705, the parent network node may map resources to beam 610D and beam 610A based at least in part on beams 610D and 610A having connected UEs. The parent network node may allocate a first portion of the available bandwidth as resources mapped to beam 610A, and allocate a second portion of the available bandwidth as resources mapped to 610D. In some aspects, some resources mapped to beam 610D and beam 610A may not be allocated to communications. In this way, the network node may forward communications via multiple beams simultaneously. This may be configured based at least in part on the ability of the network node to transmit simultaneously via different beams.
[0125] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The content described is different.

For example, the network node (e.g., using Fig.10 The communication manager 150 and / or receiving component 1002 depicted in FIG. 1 may receive an indication of a mapping of time and frequency resources to a set of beams for the network node (eg, from a parent network node), as described above.

For example, the network node (e.g., using Fig.10 The communication manager 150 and / or the communication manager 1008 depicted in the figure may forward the one or more communications via one or more beams in the beam set based at least in part on the one or more communications being associated with the time and frequency resource set, and the time and frequency resource set is mapped to the one or more beams according to a mapping of the time and frequency resources to the beam set of the network node, as described above.

[0145] although Figure 8 An example block diagram of process 800 is shown, but in some aspects, process 800 may include Figure 8 Additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in the process 800. Additionally or alternatively, two or more blocks of the blocks of process 800 may be performed in parallel.
[0146] Fig. 9is a diagram illustrating an example process 900 performed, for example, by a parent network node in accordance with the present disclosure. Example process 900 is an example of the parent network node (eg, parent network node 110) performing operations associated with mapping of time and frequency resources.
[0147] like Fig. 9 As shown, in some aspects, process 900 may include sending an indication of a mapping of time and frequency resources to a set of beams of a network node (block 910). For example, the parent network node (e.g., using Fig.11 The communication manager 150 and / or the sending component 1104 depicted in FIG. 1 may send an indication of a mapping of time and frequency resources to a set of beams for a network node, as described above.
