Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. non-provisional patent application No. 17 / 931,875, filed on September 13, 2022, entitled “MULTIPLEXING AT AFORWARDING 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 multiplexing at forwarding 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. The UE may communicate with the network nodes 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 sidelink (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

[0031] 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. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the present disclosure will be fully conveyed to those skilled in the art. It should be appreciated by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functionality, or structures and functionality other than the various aspects of the disclosure set forth herein or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the present claim.

[0032] 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 may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0033] 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 5G and beyond (e.g., 6G) RATs.

[0034] Figure 11 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, meaning 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). As another example, the network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station), meaning 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).

[0035] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link, such as a CU. 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.

[0036] 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 1 In the example shown, 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. The network node may support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move according to the location of the mobile network node 110 (e.g., a mobile network node).

[0037] 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 plurality 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 repeatedly perform 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. In this way, a single device may include more than one base station.

[0038] 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, 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 communications 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.

[0039] 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).

[0040] 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.

[0041] UE 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 may 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.

[0042] 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 in a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0043] 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.

[0044] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using network node 110 as an intermediary) using one or more side link channels. 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.

[0045] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., according to 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 to 7.125 GHz) and FR2 (24.25 GHz to 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).

[0046] 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 frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, currently higher frequency bands are 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 to 71GHz), FR4 (52.6GHz to 114.25GHz) and FR5 (114.25GHz to 300GHz). Each of these higher frequency bands falls within the EHF band.

[0047] With the above examples in mind, unless otherwise expressly 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 below 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise expressly 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.

[0048] In some aspects, the network node 110 may include a communication manager 150. As described in greater detail elsewhere herein, the communication manager 150 may send information associated with a multiplexing compatibility of the network node for communications with a first mobile station and a second mobile station to a parent network node, the first mobile station and the second mobile station being connected to the parent network node via the network node; and receive from the parent network node a first communication for the first mobile station and a second communication for the second mobile station, the first communication and the second communication being multiplexed based at least in part on the information associated with the multiplexing compatibility of the network node for communications with the first mobile station and the second mobile station. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0049] In some aspects, the parent network node 110 may include a communication manager 150. As described in greater detail elsewhere herein, the communication manager 150 may receive, from a network node, information associated with a multiplexing compatibility of the network node for communications with a first mobile station and a second mobile station, the first mobile station and the second mobile station being connected to the parent network node via the network node, and send to the network node a first communication for the first mobile station and a second communication for the second mobile station, the first communication and the second communication being multiplexed based at least in part on the information associated with the multiplexing compatibility of the network node for communications with the first mobile station and the second mobile station.

[0050] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0051] Figure 2 2 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 the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning 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., pre-coding) 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 further process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 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) detected symbols, may provide decoded data for the UE 120 to a data sink 260, and may provide decoded control information and system information to a 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 a 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 coupled to one or more transmit and / or receive components (such as antennas). Figure 2 One or more antenna elements of one or more components in.

[0056] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a 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 transmitted 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, with reference to Figures 6 to 12 ) 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 6 to 12 ) 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 may perform one or more techniques associated with multiplexing at a forwarding node (e.g., network node 110), as described in more detail elsewhere herein. For example, controller / processor 240 of network node 110, controller / processor 280 of UE 120, and / or Figure 2 Any other component of the Fig. 9 The process of 900 Fig.10 1000 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 that stores one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Fig. 9 The process of 900 Fig.10 The process 1000 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0059] In some aspects, network node 110 may include means for sending information associated with a multiplexing compatibility of the network node for communications with a first mobile station and a second mobile station to a parent network node, the first mobile station and the second mobile station being connected to the parent network node via the network node; and means for receiving, from the parent network node, a first communication for the first mobile station and a second communication for the second mobile station, the first communication and the second communication being multiplexed based at least in part on the information associated with the multiplexing compatibility of the network node for communications with the first mobile station and the second mobile station, etc. In some aspects, such means may include means for transmitting information associated with a multiplexing compatibility of the network node for communications with the first mobile station and the second mobile station to the parent network node, Figure 2 One or more components of the network node 110 are depicted, such as an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, and the like.

[0060] In some aspects, parent network node 110 may include means for receiving, from a network node, information associated with a multiplexing compatibility of the network node for communications with a first mobile station and a second mobile station, the first mobile station and the second mobile station being connected to the parent network node via the network node; and means for sending, to the network node, a first communication for the first mobile station and a second communication for the second mobile station, the first communication and the second communication being multiplexed based at least in part on the information associated with the multiplexing compatibility of the network node for communications with the first mobile station and the second mobile station, etc. In some aspects, such means may include means for transmitting, in conjunction with Figure 2 One or more components of the network node 110 are depicted, such as an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, and the like.

[0061] Although Figure 2 The blocks in the 200 and 210 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 examples described are different.

[0063] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways using various components or constituent parts. 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) performing base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "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 independently. 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 the 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 disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated 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 these units (including CU 310, DU 330, RU 340) and near-RT RIC 325, non-RTRIC 315 and SMO framework 305) may include or be coupled to one or more interfaces, which are configured to receive or send signals, data or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of these 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 the transmission medium. In some examples, each of these units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, and the wireless interface may include a receiver, a transmitter or a transceiver (such as an RF transceiver), which is configured to receive signals or send signals to one or more of the other units via a wireless transmission medium, or both.

[0068] In some aspects, 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 CU 310. 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, 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, CU310 may be implemented to communicate with DU 330 for network control and signaling.

[0069] Each DU 330 may correspond to a logical unit including 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 partition 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) (such as lower layer functional splitting). In such an 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-RTRIC 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 communicate 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 at the SMO framework 305 or the non-RT RIC 315 from a non-network data source or from a network function. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to adjust 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 examples described are different.

[0075] Figure 4 4 is a diagram illustrating an example 400 of multiplexing communications for different mobile stations on beams of a network node according to the present disclosure. Figure 4 As shown, a network node may communicate with one or more mobile stations (e.g., UE 120). The network node may communicate with a first mobile station, a second mobile station, and a third mobile station. The network node may be able to communicate with multiple mobile stations on the same beam, which may enable the network node to use frequency division multiplexing (FDM) (e.g., utilizing simultaneous or overlapping time resources) to multiplex communications for the multiple mobile stations. For example, the network node may be able to use FDM multiplexing only based at least in part on multiplexing communications on the same beam.

[0076] The network node may operate multiple beams on which the network node communicates with multiple mobile stations. For example, the network node may send communications to a mobile station on a set of beams 405A, 405B, 405C, and 405D.

[0077] As shown by reference numeral 410, the first mobile station may receive communications via beam 405B or via beam 405C, and the network node may send communications via beam 405B or via beam 405C. As shown by reference numeral 415, the second mobile station may receive communications via beam 405B, and the network node may send communications via beam 405B. As shown by reference numeral 420, the third mobile station may receive communications via beam 405C, and the network node may send communications via beam 405C.

[0078] In example 400, the network node may use FDM to multiplex communications to a first mobile station with communications to a second mobile station or with communications to a third mobile station. However, the network node may not use FDM to multiplex communications to the second mobile station with communications to the third mobile station because the second mobile station and the third mobile station are not served and / or reachable via the same beam.

[0079] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0080] Figure 5 is a diagram illustrating an example 500 of multiplexing communications for different mobile stations on beams of a network node according to the present disclosure. Figure 5 As shown, a parent network node may attempt to send communications to a first mobile station (eg, UE 120) and a second mobile station via a network node (eg, a relay, repeater, and / or forwarding node, etc.) using FDM multiplexing.

[0081] The parent network node may operate multiple beams on which the parent network node transmits communications to multiple mobile stations. For example, the network node may transmit communications to a mobile station on a set of beams 505A, 505B, 505C, and 505D.

[0082] As indicated by reference numeral 510, the network node may receive communications from a parent network node. The network node may determine that the communications using FDM multiplexing are for mobile stations that are not served by the same beam (eg, a downlink transmit beam of the network node).

[0083] The network node may operate multiple beams on which the network node communicates with connected mobile stations. For example, the network node may support a mobile station, operate a mobile station, and / or communicate with a mobile station via a set of beams 515A, 515B, 515C, and 515D. However, the network node may not support FDM-based multiplexing of communications on different beams (e.g., using simultaneous and / or overlapping communications).

[0084] Based at least in part on FDM not supporting communications on different beams, the network node may send only one of the communications to only one of the mobile stations. For example, as shown by reference numeral 520A, the network node may send communications for a first mobile station via beam 515A. Alternatively, as shown by reference numeral 520B, the network node may send communications for a second mobile station via beam 515C.

[0085] Based at least in part on the network node not supporting FDM-based multiplexing of communications on different beams, one of the communications shown in example 500 will not be forwarded by the network node. Based at least in part on not forwarding one of the communications, a mobile station associated with the one communication may send an indication of a failure to receive the communication, which may trigger a retransmission of the communication. In this way, the network node may consume power, computing, network, and / or communication resources to detect and / or correct errors caused by the failure to forward one of the communications.

[0086] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0087] In some aspects described herein, a network node may send information associated with multiplexing compatibility of the network node for communications with a first mobile station and a second mobile station to a parent network node. The first mobile station and the second mobile station may be connected to the parent network node via the network node. For example, the network node may indicate whether the network node supports FDM-based multiplexing for communications to the first mobile station and the second mobile station (e.g., based at least in part on the fact that the first mobile station and the second mobile station are reachable via the same beam of the network node).

[0088] The parent network node may transmit a first communication for a first mobile station and a second communication for a second mobile station, wherein the first communication and the second communication are multiplexed based at least in part on information associated with multiplexing compatibility of the network node for communications with the first mobile station and the second mobile station. For example, the parent network node may transmit the first communication and the second communication using FDM-based multiplexing (e.g., using simultaneous transmission and / or overlapping time resources) based at least in part on information indicating that the network node supports multiplexing of communications for the first mobile station and the second mobile station using FDM-based multiplexing.

[0089] In some aspects, a network node may assign connected mobile stations to different beams of the network node. For example, the network node may assign mobile stations to beams during initial acquisition of the mobile station and / or during a beam management process. In some aspects, a network node (e.g., a relay and / or forwarding node) may continuously track beams assigned to connected mobile stations (e.g., to maintain a communication link with the mobile station).

[0090] The parent network node may know that the parent network node may use the beam directed toward the network node to reach the connected mobile station. In this way, all mobile stations served by the network node appear to the parent network node to be served by the same beam of the parent network node.

[0091] The network node may provide, to the parent network node, information associated with multiplexing capabilities of the network node associated with forwarding communications to a mobile station served by the network node (e.g., communicating with the parent network node via the network node). For example, the network node may indicate a plurality of mobile stations served by the same beam of the network node (e.g., a list of UEs that may be multiplexed with allocations in the same time slot).

[0092] In some aspects, when multiple mobile stations are identified as sharing the same beam of the network node (e.g., the downlink transmit beam of the network node), the network node may initiate sending a report to the parent network node. This may occur when the beam and / or beam assignment changes due to mobile station motion and / or a changed configuration of the network node. In some aspects, the network node may initiate periodic reporting on all mobile station groups even when the beam and / or beam assignment has not changed.

[0093] In some aspects, the parent network node may query the network node for pairs or groups of mobile stations that the parent network node wants to reuse in subsequent allocations. The parent network node may query the network node periodically or semi-periodically and / or may indicate that the network node will provide information periodically or semi-periodically.

[0094] In some aspects, the information may include beam associations, such as a list of mobile stations (e.g., using mobile station identifiers) that may be multiplexed using FDM (e.g., using simultaneous transmissions and / or overlapping time resources). For example, the information may indicate {{UE1, UE3}, {UE2, UE4}, {UE5}}.

[0095] In some aspects, the information may include a joint signal strength report. For example, the information may indicate the RSRP from all connected mobile stations for one or more beams of the network node. For example, two mobile stations may be assigned different beams, but may support operation on a shared beam with reduced performance. In some aspects, the parent network node may use this information to, for example, send downlink control information (DCI) with future allocations to one of the mobile stations (a small payload for a mobile station with lower signal strength for a shared beam) while sending data to another mobile station (e.g., a mobile station with higher signal strength for a shared beam), or similarly in the uplink.

[0096] In some aspects, a network node may receive a mobile station request for a system information block (SIB) and may forward the mobile station request for the SIB (e.g., an extended SIB) to a parent network node. The network node may provide the information to the parent network node based at least in part on forwarding the mobile station request for the SIB to the parent network node. The information may include, for example, an indication of one or more additional mobile stations (e.g., in addition to the mobile station that sent the mobile station request) that may receive downlink communications (e.g., downlink data and / or downlink control information) using FDM-based multiplexing (also referred to herein as FDM multiplexing) such that the downlink communications are FDM multiplexed with the SIB. For example, the one or more additional mobile stations may receive downlink communications that are FDM-based multiplexed with the SIB based at least in part on the mobile station and the one or more additional mobile stations being reachable from a single beam (e.g., having the same downlink spatial filter applied by the network node).

[0097] Based at least in part on a network node providing information associated with the network node's multiplexing compatibility for communications with mobile stations connected to the parent network node via the network node, the parent network node may avoid multiplexing communications for incompatible mobile stations and / or conserve power, computing, network, and / or communication resources that might otherwise be used to detect failures of communications that were not forwarded and / or to retransmit the communications.

[0098] Figure 6 is a diagram of an example 600 associated with multiplexing at a forwarding 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 a mobile station (e.g., UE 120). In some aspects, the network node, parent network node, and / or mobile station may be part of a wireless network (e.g., wireless network 100). The network node, parent network node, and / or mobile station may be part of a wireless network (e.g., wireless network 100). Figure 6 The operations shown are performed with a wireless connection already established.

[0099] As indicated by reference numeral 605, the parent network node may send configuration information, and the network node may receive the 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 a parent network node or other network device) and / or explicit configuration information for the network node to use to configure the network node, etc.

[0100] In some aspects, the configuration information may indicate that the network node is to send information associated with the multiplexing capabilities of the network node for communications with the first mobile station and the second mobile station.

[0101] 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.

[0102] As indicated by reference numeral 610, the network node and the mobile station may perform a beam management procedure. For example, the network node may perform a beam management procedure during an initial connection procedure with the mobile station, and / or the network node may perform a beam management procedure during an ongoing connection with the mobile station to update beam selection for mobile stations within coverage of the network node. For example, the network node may perform a beam management procedure with a first mobile station and a second mobile station.

[0103] As indicated by reference numeral 615, the network node may identify support of the beam for communications with the plurality of mobile stations. For example, the network node may identify beams selected for the plurality of mobile stations (e.g., network node beams for transmission and / or reception). Additionally or alternatively, the network node may identify beams that are not selected for each mobile station reachable via the beam. For example, the beam may not be the strongest beam for communicating with at least one of the mobile stations reachable via the beam (e.g., may not have the highest signal strength among all network node beams).

[0104] As shown by reference numeral 620, a network node may receive and a parent network node may send a request for information associated with the multiplexing capabilities of the network node. For example, the request may indicate an information element to be included in the information to be sent to the parent network node. In some aspects, the request may indicate a list of mobile stations for which FDM multiplexing (e.g., using simultaneous transmission and / or reception, or using overlapping resources for transmission and / or reception) may be used to multiplex communications. In some aspects, the request may indicate a list of mobile stations including service beams and serviced by each service beam of the network node. In some aspects, the request may indicate a list of mobile stations including service beams and reachable by each service beam. In some aspects, the request may indicate a list of service beams and an indication of the signal strength for communicating with a connected mobile station via the corresponding service beam.

[0105] The network node may receive, and the mobile station may send, a request for a SIB as indicated by reference numeral 625. For example, the mobile station may request the SIB as an extended SIB and / or a supplemental SIB for the mobile station to, for example, synchronize with and / or acquire a connection with a parent network node.

[0106] As indicated by reference numeral 630, the network node may forward the request for the SIB to a parent network node.

[0107] As indicated by reference numeral 635, the network node may transmit and the parent network node may receive information associated with the multiplexing capability of the network node for communication with a first mobile station and a second mobile station of mobile stations connected to the parent network node via the network node.

[0108] In some aspects, the information may include a report of beam assignments for connected mobile stations, an indication of signal strength of signals communicated between the network node and connected mobile stations according to the network node's beams, or an indication of one or more mobile stations in a set for which the network node supports TDM.

[0109] In some aspects, the network node may send the information based at least in part on an identification of a beam supporting communication with the first mobile station and the second mobile station, an identification that the beam no longer supports communication with the first mobile station and the second mobile station, receiving a request for the information (e.g., as described in conjunction with reference numeral 620), or a configuration for a periodicity for sending the information (e.g., as indicated in the configuration information described in conjunction with reference numeral 605), and / or forwarding a request for the SIB, etc.

[0110] As shown by reference numeral 640, the network node may receive, and the parent network node may send, communications for mobile stations using multiplexing based at least in part on information sent by the network node. In some aspects, these communications may include a first communication for a first mobile station and a second communication for a second mobile station. These communications may be FDM-based multiplexing for mobile stations reachable via the same beam of the network node and / or for mobile stations associated with the same beam of the network node (e.g., having the same serving beam).

[0111] For mobile stations that are not reachable via the same beam of the network node, communications may be multiplexed based on time division multiplexing (TDM). For example, communications may be multiplexed using TDM based at least in part on the first mobile station and the second mobile station being associated with different beams of the network node, and / or based at least in part on the first mobile station and the second mobile station having signal strengths associated with the same beam of the network node that fail to meet a threshold.

[0112] In some aspects, the first communication may include data or control communication, and the second communication may include SIB. In some aspects, the SIB and the first communication may use different channels of the network on different frequency resources.

[0113] As shown at reference numeral 645, the network node may forward communications to the first mobile station and the second mobile station. For example, the network node may send a first communication for the first mobile station and a second communication for the second mobile station. The network node may forward the first communication and the second communication based at least in part on multiplexing applied by the parent network node to send communications for the mobile stations, as described in conjunction with reference numeral 640.

[0114] For mobile stations reachable via the same beam of the network node, the communication may be FDM-based multiplexing. For mobile stations not reachable via the same beam of the network node, the communication may be TDM-based multiplexing (e.g., using resources that at least partially overlap in time). In this way, the network node may send a first communication to a first mobile station during a first set of time resources, and may send a second communication to a second mobile station during a second set of time resources that do not overlap with the first set of time resources.

[0115] In some aspects, TDM-based multiplexing of communications is used for mobile stations that are not reachable via the same beam of a network node and / or are not associated with the same beam (e.g., have different serving beams). For example, communications can be multiplexed using TDM based at least in part on a first mobile station and a second mobile station being associated with different beams of a network node and / or based at least in part on the first mobile station and the second mobile station having signal strengths associated with the same beam of the network node that fail to meet a threshold.

[0116] This may avoid the network node failing to forward one of the first communication or the second communication.

[0117] As indicated by reference numeral 650, the network node may detect a change in multiplexing capabilities for multiplexing communications to the mobile station. For example, the network node may detect that a serving beam associated with the mobile station has changed and / or reachability via a beam has changed, etc. In some aspects, the network node may detect the change satisfying a change threshold.

[0118] As indicated by reference numeral 655, the network node may send updates to the information. For example, the network node may send new information associated with the multiplexing capabilities of the network node. Alternatively, the network node may send a reduced amount of information to update one or more information elements of the information. For example, the network node may indicate that a mobile station is added to a list of mobile stations reachable by a beam and / or may remove a mobile station from a list of mobile stations reachable by a beam. Additionally or alternatively, the network node may indicate updates to the signal strength of the mobile station when communicating via one or more beams of the network node.

[0119] Based at least in part on a network node providing information associated with the network node's multiplexing compatibility for communications with mobile stations connected to the parent network node via the network node, the parent network node may avoid multiplexing communications for incompatible mobile stations and / or conserve power, computing, network, and / or communication resources that might otherwise be used to detect failures of communications that were not forwarded and / or to retransmit the communications.

[0120] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0121] Figure 7 is a diagram of an example 700 associated with multiplexing at a forwarding node 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 a mobile station (e.g., UE 120). In some aspects, the network node, parent network node, and / or mobile station may be part of a wireless network (e.g., wireless network 100). The network node, parent network node, and / or mobile station may be part of a wireless network (e.g., wireless network 100). Figure 7 The operations shown are performed with a wireless connection already established.

[0122] like Figure 7 As shown, the parent network node may attempt to send communications to a first mobile station (e.g., UE 120), a second mobile station, and a third mobile station via a network node (e.g., a relay, repeater, and / or forwarding node, etc.) using FDM multiplexing. The parent network node may support sending communications using FDM-based multiplexing and / or TDM-based multiplexing.

[0123] As indicated by reference numeral 705, the network node may transmit information of the multiplexing capabilities of the network node for communications with mobile stations connected to the parent network node via the network node. For example, the network node may indicate a set of one or more of the mobile stations that may use at least partially overlapping time resources (e.g., using FDM).

[0124] The network node may support, operate, and / or communicate with a mobile station via a set of beams 710A, 710B, 710C, and 710D. However, the network node may not support FDM-based multiplexing of communications on different beams (e.g., using simultaneous and / or overlapping communications). As shown in example 700, a first mobile station may have communications multiplexed with communications for a second mobile station or for a third mobile station. This is because the first mobile station may be reachable via beam 710B with the second mobile station or reachable via beam 710C with the third mobile station.

[0125] As indicated by reference numeral 715, the network node may receive communications for the mobile stations using the multiplexing capability. For example, the communications may include FDM-based communications for the first mobile station and the second mobile station, FDM-based communications for the first mobile station and the third mobile station, and / or TDM-based communications for the second mobile station and the third mobile station (e.g., on non-overlapping time resources).

[0126] The network node may send communications to the second mobile station as indicated by reference numeral 720, and the network node may send communications to the first mobile station using beam 710B as indicated by reference numeral 725. For example, the network node may multiplex communications to the second mobile station with communications to the first mobile station using FDM (with at least partially overlapping time resources).

[0127] The network node may send communications to the third mobile station as indicated by reference numeral 730, and the network node may send communications to the first mobile station using beam 710C as indicated by reference numeral 725. For example, the network node may multiplex communications to the third mobile station with communications to the first mobile station using FDM (with at least partially overlapping time resources).

[0128] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.

[0129] Figure 8 8 is a diagram illustrating examples 800, 810, and 820 of beam management procedures according to the present disclosure. Figure 8 As shown, examples 800, 810, and 820 include UE 120 communicating with network node 110 in a wireless network (e.g., wireless network 100). Figure 8 The devices shown are provided as examples, and the wireless network may support communication and beam management between other devices (e.g., between UE 120 and network node 110 or a transmit receive point (TRP), between a mobile terminal node and a control node, between an integrated access and backhaul (IAB) child node and an IAB parent node, between a scheduled node and a scheduling node). In some aspects, UE 120 and network node 110 may be in a connected state (e.g., an RRC connected state).

[0130] like Figure 8As shown, example 800 may include a network node 110 (e.g., one or more network node devices such as RU, DU and / or CU, etc.) and a UE 120, the network node communicating with the UE to perform beam management (e.g., using a channel state information reference signal (CSI-RS) and / or a synchronization signal block (SSB)). Example 800 depicts a first beam management procedure (e.g., P1CSI-RS beam management). The first beam management procedure may be referred to as a beam selection procedure, an initial beam acquisition procedure, a beam scanning procedure, a cell search procedure, and / or a beam search procedure. As shown in FIG. Figure 8 As shown in example 800, CSI-RS may be configured to be sent from network node 110 to UE 120. CSI-RS may be configured to be periodic (e.g., using RRC signaling), semi-persistent (e.g., using medium access control (MAC) control element (MAC-CE) signaling), and / or aperiodic (e.g., using DCI).

[0131] The first beam management procedure may include the network node 110 performing beam scanning on multiple transmit (Tx) beams. The network node 110 may use each transmit beam used for beam management to transmit a CSI-RS. In order to enable the UE 120 to perform receive (Rx) beam scanning, the network node may use a transmit beam to transmit each CSI-RS multiple times (e.g., with repetitions) within the same RS resource set, so that the UE 120 can sweep the receive beam in multiple transmit instances. For example, if the network node 110 has a set of N transmit beams and the UE 120 has a set of M receive beams, the CSI-RS may be transmitted M times on each of the N transmit beams, so that the UE 120 can receive M instances of the CSI-RS per transmit beam. In other words, for each transmit beam of the network node 110, the UE 120 may perform beam scanning on the receive beam of the UE 120. Therefore, the first beam management procedure may enable UE 120 to measure CSI-RS on different transmit beams using different receive beams to support selection of a network node 110 transmit beam / UE 120 receive beam pair. UE 120 may report the measurement results to network node 110 to enable network node 110 to select one or more beam pairs for communication between network node 110 and UE 120. Although example 800 has been described in conjunction with CSI-RS, the first beam management procedure may also use SSBS for beam management in a manner similar to that described above.

[0132] like Figure 8As shown, example 810 may include a network node 110 and a UE 120 communicating to perform beam management using CSI-RS. Example 810 depicts a second beam management procedure (e.g., P2 CSI-RS beam management). The second beam management procedure may be referred to as a beam refinement procedure, a network node beam refinement procedure, a TRP beam refinement procedure, and / or a transmit beam refinement procedure. Figure 8 As shown in example 810, a CSI-RS may be configured to be sent from a network node 110 to a UE 120. The CSI-RS may be configured to be non-periodic (e.g., using a DCI). The second beam management procedure may include the network node 110 performing beam scanning on one or more transmit beams. The one or more transmit beams may be a subset of all transmit beams associated with the network node 110 (e.g., determined at least in part based on measurement results reported by the UE 120 in conjunction with the first beam management procedure). The network node 110 may use each of the one or more transmit beams for beam management to transmit a CSI-RS. The UE 120 may measure each CSI-RS using a single (e.g., identical) receive beam (e.g., determined at least in part based on measurement results performed in conjunction with the first beam management procedure). The second beam management procedure may enable the network node 110 to select the best transmit beam based at least in part on measurements of the CSI-RS reported by the UE 120 (eg, measured by the UE 120 using a single receive beam).

[0133] like Figure 8 As shown, example 820 depicts a third beam management procedure (e.g., P3 CSI-RS beam management). The third beam management procedure may be referred to as a beam refinement procedure, a UE beam refinement procedure, and / or a receive beam refinement procedure. Figure 8As shown in example 820, one or more CSI-RS may be configured to be sent from the network node 110 to the UE 120. The CSI-RS may be configured to be non-periodic (e.g., using DCI). The third beam management process may include the network node 110 using a single transmit beam (e.g., determined at least in part based on measurement results reported by the UE 120 in conjunction with the first beam management procedure and / or the second beam management procedure) to send one or more CSI-RS. In order to enable the UE 120 to perform receive beam scanning, the network node may use the transmit beam to send multiple (e.g., with repetitions) CSI-RS within the same RS resource set, so that the UE 120 can sweep one or more receive beams in multiple transmission instances. The one or more receive beams may be a subset of all receive beams associated with the UE 120 (e.g., determined at least in part based on measurement results performed in conjunction with the first beam management procedure and / or the second beam management procedure). The third beam management procedure may enable the network node 110 and / or the UE 120 to select the best receive beam based at least in part on reported measurement results received from the UE 120 (e.g., reported measurement results of the CSI-RS of the transmit beam using the one or more receive beams).

[0134] In some respects, Figure 7 The network nodes and mobile stations can execute and combine Figure 8 The beam management procedure described is similar to the beam management procedure.

[0135] As indicated above, Figure 8 is provided as an example of a beam management procedure. Other examples of beam management procedures can be found in Figure 8 For example, the UE 120 and the network node 110 may perform the third beam management procedure before performing the second beam management procedure, and / or the UE 120 and the network node 110 may perform a similar beam management procedure to select a UE transmit beam.

[0136] Fig. 9 is a diagram illustrating an example process 900 performed, for example, by a network node in accordance with the present disclosure. Example process 900 is an example of a network node (eg, network node 110) performing operations associated with multiplexing at a forwarding node.

[0137] like Fig. 9 As shown, in some aspects, process 900 may include sending information associated with a multiplexing compatibility of the network node for communication with a first mobile station and a second mobile station to a parent network node, the first mobile station and the second mobile station being connected to the parent network node via the network node (block 910). Fig.11The communication manager 150 and / or sending component 1104 depicted in FIG. 1 may send to a parent network node information associated with the network node's multiplexing compatibility for communications with a first mobile station and a second mobile station, the first mobile station and the second mobile station being connected to the parent network node via the network node, as described above.

Fig.11 The communication manager 150 and / or receiving component 1102 depicted in the figure can receive a first communication for a first mobile station and a second communication for a second mobile station from a parent network node, and the first communication and the second communication are multiplexed based at least in part on information associated with the multiplexing compatibility of the network node for communications with the first mobile station and the second mobile station, as described above.

[0150] although Fig. 9 Example blocks of process 900 are shown, but in some aspects, process 900 may include Fig. 9 The blocks depicted may be additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted. Additionally or alternatively, two or more of the blocks of process 900 may be performed in parallel.

[0151] Fig.10is a diagram illustrating an example process 1000 performed, for example, by a parent network node in accordance with the present disclosure. Example process 1000 is an example of a parent network node (eg, parent network node 110) performing operations associated with multiplexing at a forwarding node.

[0152] like Fig.10 As shown, in some aspects, process 1000 may include receiving, from a network node, information associated with a multiplexing compatibility of the network node for communications with a first mobile station and a second mobile station, the first mobile station and the second mobile station being connected to a parent network node via the network node (block 1010).

[0154] Process 1000 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.
