Description

[0001] Cross-reference to related applications

[0002] This patent application claims priority to U.S. Patent Application No. 18 / 330,269, filed June 6, 2023, entitled “Interference Assistance Information for Multi-User Multiple-Input Multiple-Output Groups”, assigned to the assignee of this application. The disclosure of the earlier application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0003] All aspects of this disclosure relate to wireless communication in general, and to techniques and apparatus for providing interference-aiding information for multi-user multiple-input multiple-output groups. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable 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 issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with network nodes via downlink and uplink communication. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via local links (e.g., sidelinks (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links, etc.).

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency; reducing costs; improving service; utilizing new spectrum; and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), and using CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to better integrate with other open standards. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

[0027] Figure 9 This is a diagram of an example device for wireless communication according to the present disclosure. Detailed Implementation

[0028] The various aspects generally relate to interference assistance information for multi-user (MU)-multiple-input multiple-output (MIMO) groups. Some aspects more specifically relate to the flexible negotiation and configuration of MU-MIMO groups for group-based delivery of interference assistance information. In some examples, a UE may have an initial assignment to a first MU-MIMO group and may receive associated first interference assistance information. The UE may receive first communication and attempt to eliminate and / or suppress interference to the first communication, at least in part based on the first interference assistance information. The UE may provide interference assistance feedback indicating the performance of interference elimination and / or suppression, at least in part based on the first interference assistance information.

[0029] The UE may be assigned to a second MU-MIMO group (e.g., replacing or excluding the first MU-MIMO group) based at least in part on interference-assisted feedback, and the UE may receive associated second interference-assisted information. The UE may receive second communications and may attempt to eliminate and / or suppress interference to the second communications based at least in part on the second interference-assisted information.

[0030] In some respects, the UE can receive first communication via a first set of time and frequency resources associated with a first MU-MIMO group, and can receive second communication via a second set of time and frequency resources associated with a second MU-MIMO group. In this way, the assignment to the first or second MU-MIMO group can be transparent to the UE.

[0031] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques can be used to improve interference assistance information for a UE by providing interference assistance feedback. For example, interference assistance information can be improved based at least in part on support for the assignment and associated interference assistance information to updated MU-MIMO groups. Based at least in part on the improved interference assistance information, the UE can save power, processing, network, and / or communication resources that might otherwise have been consumed by detecting and / or correcting errors associated with outdated interference assistance information (e.g., associated with suboptimal MU-MIMO group assignments). Additionally or alternatively, based at least in part on the improved interference assistance information, the UE and network nodes can communicate with improved spectral efficiency, cell throughput, and / or cell coverage, etc.

[0032] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure can be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of protection of this disclosure to those skilled in the art. Those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of the disclosure herein, whether implemented independently or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods implemented using structures, functions, or structures and functions other than or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of these claims.

[0033] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various boxes, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0034] Although terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used herein to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or 5G and later (e.g., 6G) RATs.

[0035] Figure 1 This 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., 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. Network node 110 is a network node that communicates with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that the aggregated 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, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 is configured to utilize a protocol stack that is physically or logically distributed among 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)).

[0036] In some examples, network node 110 is or includes network nodes (such as RUs) that communicate with UE 120 via a radio access link. In some examples, network node 110 is or includes network nodes (such as DUs) that communicate with other network nodes 110 via a fronthaul or midhaul link. In some examples, network node 110 is or includes network nodes (such as CUs) that communicate with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some examples, network node 110 (such as aggregated network node 110 or 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. Network node 110 may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, Transmit / Receive Points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAn nodes, or combinations thereof. In some examples, network nodes 110 can interconnect with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0037] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of ​​network node 110 and / or the network node subsystem serving that coverage area. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 used for macrocells may be referred to as a macro network node. Network node 110 used for picocells may be referred to as a pico network node. The network node 110 used for femtocells can be referred to as a femtocell network node or a home network node. Figure 1In the example shown, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. Network nodes can support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographical area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0038] In some aspects, the term "base station" or "network node" may refer to an aggregated 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, "base station" or "network node" may refer to a CU, DU, 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 network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or repeatedly perform at least a portion of that 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 can be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function rather than another. In this way, a single device can include more than one base station.

[0039] Wireless network 100 may include one or more relay stations. A relay station is a network node that can receive data transmissions from upstream nodes (e.g., network node 110 or UE 120) and transmit data to downstream nodes (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions for other UE 120s. Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 for relay communication may be referred to as a relay station, relay base station, relay network node, relay node, relay, etc.

[0040] Wireless network 100 can be a heterogeneous network, comprising 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 effects on interference in wireless network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0041] Network controller 130 may be coupled to or communicate with a group of network nodes 110, and may provide coordination and control for these network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul or midhaul link. Network nodes 110 may also communicate directly with each other, or indirectly via a wireless or wired backhaul link. In some aspects, network controller 130 may be a CU or a core network device, or may include a CU or a core network device.

[0042] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or 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, industrial manufacturing equipment, a GPS device, the UE function of a network node, and / or any other suitable device configured to communicate via wireless or wired media.

[0043] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags that can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0044] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency in a given geographical area can support a single RAT to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0045] 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 device 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.

[0046] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been designated as frequency ranges FR1 (410MHz–7.125GHz) and FR2 (24.25GHz–52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30GHz–300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0047] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have identified the operating bands used for these mid-band frequencies as the frequency range designation FR3 (7.125GHz–24.25GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6GHz. For example, three higher operating frequency bands have been identified as the 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.

[0048] Considering the examples above, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" is used herein, it can broadly refer to frequencies below 6 GHz, within FR1, or including intermediate frequency bands. Furthermore, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" is used herein, it can broadly refer to frequencies that can include intermediate frequency bands, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. Modifications to frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) are contemplated, and the techniques described herein are applicable to those modified frequency ranges.

[0049] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive interference assistance information associated with interference cancellation or suppression for one or more communications; transmit interference assistance feedback that is at least partially based on the interference assistance information to indicate one or more parameters for interference cancellation or suppression; and receive communications within a set of time and frequency resources associated with a MU-MIMO group that is associated with the interference assistance feedback. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0050] In some aspects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may send interference assistance information to UEs in a first MU-MIMO group, the interference assistance information being associated with interference cancellation or suppression for one or more communications; receive interference assistance feedback from UEs in the MU-MIMO group, the interference assistance feedback indicating one or more parameters for interference cancellation or suppression based at least in part on the interference assistance information; and send communications to UEs within a set of time and frequency resources associated with a second MU-MIMO group, based at least in part on the interference assistance feedback. Additionally or alternatively, communication manager 150 may perform one or more other operations described herein.

[0051] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0052] Figure 2 This is a diagram illustrating example 200 of communication between network node 110 and UE 120 in a wireless network 100 according to this disclosure. Network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). Network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and modems 232. In some examples, network node 110 may include an interface, communication components, or another component facilitating communication with UE 120 or another network node. Some network nodes 110 may not include radio frequency components facilitating direct communication with UE 120, such as one or more CUs or one or more DUs.

[0053] At network node 110, transmitting processor 220 can receive data from data source 212 intended for use by UE 120 (or a group of UEs 120). Transmitting processor 220 can select one or more modulation and decoding 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 can process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120 and can provide data symbols for UE 120. Transmitting processor 220 can 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. Transmitting processor 220 can 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 signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a set of corresponding modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process the output sample stream (e.g., convert to analog, amplify, filter, and / or up-convert) to obtain a downlink signal. Modems 232a to 232t can transmit a set of downlink signals (e.g., T downlink signals) via a set of corresponding antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0054] At UE 120, a set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 and / or other network nodes 110 and can 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 can be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or combinations thereof. For example, controller / processor 280 may include multiple controllers / processors, wherein any combination of multiple controllers / processors (including a single controller / processor, or two or more controllers / processors) can perform any combination of the functions described herein. For example, a first combination of multiple controllers / processors can perform... Figure 6 Any combination of aspects, and a second combination of multiple controllers / processors is executable. Figure 6 Any combination of aspects of the controller / processor (where the first combination of controllers / processors may be the same as or different from the second combination of controllers / processors). The channel processor can determine the Reference Signal Received Power (RSRP) parameter, Received Signal Strength Indicator (RSSI) parameter, Reference Signal Received Quality (RSRQ) parameter, and / or CQI parameter, etc. In some examples, one or more components of the UE120 may be included in the housing 284.

[0055] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with network node 110 via communication unit 294.

[0056] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include 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., or may 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 (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements and / or be coupled to one or more transmitting and / or receiving components (such as...). Figure 2 One or more antenna elements (one or more components in a )

[0057] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 can 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 network node 110. In some examples, the modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to execute this document (e.g., reference). Figures 5 to 9 ( ) any aspect of the methods described in the method.

[0058] At network node 110, uplink signals from UE 120 and / or other UEs can be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232 (shown as DEMOD)), detected by MIMO detector 236 (where applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Controller / processor 240 can include one or more controllers, one or more processors, or combinations thereof. For example, controller / processor 240 can include multiple controllers / processors, wherein any combination of multiple controllers / processors (including a single controller / processor, or two or more controllers / processors) can perform any combination of the functions described herein. For example, a first combination of multiple controllers / processors can perform... Figure 7 Any combination of aspects, and a second combination of multiple controllers / processors is executable. Figure 7 Any combination of aspects of the controller / processor (where a first combination of controllers / processors may be the same as or different from a second combination of controllers / processors). Network node 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of network node 110 may include modulator and demodulator. In some examples, network node 110 includes transceiver. 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. Transceiver may be used by processor (e.g., controller / processor 240) and memory 242 to execute this document (e.g., reference). Figures 5 to 9 ( ) any aspect of the methods described in the method.

[0059] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component may perform one or more techniques associated with interference-aiding information for MU-MIMO groups, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component that can be executed or bootstrap, for example Figure 6 Process 600 Figure 7The operation of process 700 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code 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, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, transformation, and / or interpretation), one or more instructions may cause one or more processors, UE 120, and / or network node 110 to execute or bootstrap, for example... Figure 6 Process 600 Figure 7 The operation of process 700 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transformation instructions, compilation instructions, and / or interpretation instructions, etc.

[0060] In some aspects, the UE includes components for receiving interference assistance information associated with interference cancellation or suppression for one or more communications (e.g., using antenna 252, modem 254, MIMO detector 256, receive processor 258, controller / processor 280, and / or memory 282, etc.); components for transmitting interference assistance feedback that indicates one or more parameters for interference cancellation or suppression based at least in part on the interference assistance information (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, modem 254, antenna 252, and / or memory 282, etc.); and / or components for receiving communications within a set of time and frequency resources associated with a MU-MIMO group, which is associated with the interference assistance feedback (e.g., using antenna 252, modem 254, MIMO detector 256, receive processor 258, controller / processor 280, and / or memory 282, etc.). Components used by the UE to perform the operations described herein may include one or more of the following: communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0061] In some aspects, the network node includes components for transmitting interference assistance information to UEs in a first MU-MIMO group, the interference assistance information being associated with interference cancellation or suppression for one or more communications (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, and / or memory 242, etc.); components for receiving interference assistance feedback from UEs in the MU-MIMO group, the interference assistance feedback being at least partially based on the interference assistance information to indicate one or more parameters for interference cancellation or suppression (e.g., using antenna 234, modem 232, MIMO detector 236, receive processor 238, controller / processor 240, and / or memory 242, etc.); and / or components for transmitting communications to UEs within a set of time and frequency resources associated with a second MU-MIMO group, at least partially based on the interference assistance feedback (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, and / or memory 242, etc.). Components used by network nodes to perform the operations described herein may include one or more of the following: a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0062] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0063] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The examples described are different.

[0064] Communication systems (such as 5G NR systems) can be deployed in various ways with a variety of components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAn nodes, core network nodes, network elements, base stations, or network equipment can be implemented in aggregated or decomposed architectures. For example, base stations (such as Node B (NB), evolved NB (eNB), NR base stations, 5G NB, access points (APs), TRPs, or cells, etc.) or one or more units (or components) performing base station functions can be implemented as aggregated base stations (also known as standalone base stations or monolithic base stations) or decomposed base stations. A "network entity" or "network node" can 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 combinations thereof).

[0065] Aggregated base stations (e.g., aggregated network nodes) can 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 cell). Decomposed base stations (e.g., decomposed network nodes) can be configured to utilize a protocol stack that is physically or logically distributed across two or more cells (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the 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. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual cell, such as a Virtual Central Unit (VCU), a Virtual Distributed Unit (VDU), or a Virtual Radio Unit (VRU), etc.

[0066] Base station type operation or network design can consider the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in IAB networks, Open Radio Access Networks (O-RAn (such as network configurations sponsored by the O-RAn Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate the scaling of communication systems by dividing base station functionality into one or more independently deployable units. Decomposed base stations can include functionality implemented across two or more units at various physical locations, as well as functionality virtually implemented for at least one unit, which enables flexibility in network design. Each unit of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0067] Figure 3This is an illustration of an example disaggregated base station architecture 300 according to this disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as 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 a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0068] Each unit in the clusters (including CU 310, DU 330, RU 340), as well as the near-RT RIC 325, non-RT RIC 315, and SMO frame 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cluster, or an associated processor or controller providing instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more units in other clusters via transmission media. In some examples, each unit in the cluster may include a wired interface and a wireless interface configured to receive signals via a wired transmission media or transmit signals to one or more units in other clusters, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals via a wireless transmission media or transmit signals to one or more units in other clusters, or both.

[0069] In some aspects, the CU 310 can host one or more higher-level 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 can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can be logically divided into one or more CU-UP units and one or more CU-CP units. CU-UP units can communicate bidirectionally with CU-CP units via an interface (such as an E1 interface when implemented in an O-RAn configuration). The CU 310 can be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.

[0070] Each DU 330 may correspond to a logical unit comprising one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, the DU 330 may host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as those implemented by 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 configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0071] Each RU 340 can implement lower-layer functionality. In some deployments, an RU 340 controlled by a DU 330 can 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, based on function splitting (e.g., function splitting defined by 3GPP) (such as lower-layer function splitting). In this architecture, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UE 120s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAn architecture (such as vRAn architecture).

[0072] The SMO framework 305 can be configured to support the deployment and provisioning of both non-virtualized and virtualized network elements in the RAN. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 305 can be configured to interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the 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 the hardware aspects of the 4G RAN, such as the Open eNB (O-eNB) 311, via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0073] The non-RT RIC 315 can be configured to include logic functions that enable non-real-time control and optimization of RAn components and resources, including AI / ML workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325, such as via an A1 interface. The near-RT RIC 325 can be configured to include logic functions that enable near real-time control and optimization of RAn components and resources via an interface such as an E2 interface that connects one or more CU 310s, one or more DU 330s, or both, and an O-eNB to the near-RT RIC 325.

[0074] In some implementations, to generate AI / ML models 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. This information can be utilized by the near-RT RIC 325 and may be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or 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 in performance and employ AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAn management policies (such as A1 interface policies).

[0075] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0076] Figure 4 This is a diagram illustrating example 400 of MU-MIMO group resource allocation according to this disclosure. Figure 4 In this context, a network node may use a first set of time and frequency resources and a first set of spatial layers to communicate with a UE in a first MU-MIMO group. A network node may also use a second set of time and frequency resources and a second set of spatial layers to communicate with a UE in a second MU-MIMO group. While this document uses the example of a layer as a spatial layer for description, other examples of layers may be formed using other techniques such as demodulation reference signal (DMRS) sequences, code division multiplexing (CDM) layers, and / or pre-decoding, etc.

[0077] like Figure 4As shown, a network node can use MU-MIMO group allocation 402 (e.g., a first MU-MIMO group allocation) to communicate with UEs in a first MU-MIMO group. MU-MIMO group allocation 402 may include a set of time and frequency resources and may be associated with a set of layers in the spatial domain. A network node can also use MU-MIMO group allocation 404 (e.g., a second MU-MIMO group) to communicate with UEs in a second MU-MIMO group. A network node can use shared allocation 406 to communicate with UEs constituting the first MU-MIMO group and with UEs constituting the second MU-MIMO group.

[0078] MU-MIMO group allocation may include a set of all resource blocks (RBs) and symbols in a time slot, through which the same set of UE channels and layers are scheduled. UE assignment to a MU-MIMO group may indicate that the UE's allocation (e.g., in the frequency domain) overlaps at least partially with other UEs in the MU-MIMO group (e.g., up to N other UEs). A UE may be included in one or more MU-MIMO groups (e.g., two or more MU-MIMO groups). In some networks, in addition to or alternatively to the frequency domain allocation of MU-MIMO groups, network nodes may also use the time domain allocation of MU-MIMO groups.

[0079] The UE can receive downlink control information (DCI) associated with data communications scheduled for the UE (e.g., Physical Downlink Shared Channel (PDSCH) communications). In some scenarios, the UE can use a demodulation reference signal (DMRS) to receive data communications via multiple layers or on a single layer of multiple resource layers used for communication with other UEs (e.g., in MU-MIMO groups or adjacent MU-MIMO groups). In some networks, the UE can use data from the data communications to demodulate the DMRS. In some examples, the UE may be unaware of the DMRS used for communications by other UEs, or the UE may be aware of the DMRS of other MU-MIMO groups to achieve rate matching and reduce DMRS pollution, etc.

[0080] In some networks, UEs constituting a MU-MIMO group can be considered semi-static within an active window. In some examples, specific allocations of UEs within a MU-MIMO group (e.g., layer RB and / or symbol splitting) can be assigned or reassigned on a slot basis (e.g., dynamic allocation within a MU-MIMO group).

[0081] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0082] In some networks, network nodes can provide network-assisted interference cancellation and suppression information to one or more UEs. For example, network nodes can provide interference assistance information to increase spectral efficiency in noisy environments, which can support increased cell capacity and / or performance.

[0083] In some aspects described herein, UEs and network nodes can participate in capability negotiation that supports interference cancellation processes for multiple UE receivers. For example, network nodes can provide flexible assignment of UEs to MU-MIMO groups by reducing scheduler and / or beam management constraints. In some aspects, network nodes can provide per-timeslot interference assistance information, and / or UEs can provide feedback reports to facilitate UE assignment within MU-MIMO groups. In this way, network nodes can save power, communication, and / or network resources that might otherwise be consumed by indicating interference assistance information to each UE using separate messages. Additionally or alternatively, network nodes can update interference assistance information, at least in part, based on feedback, by reassigning UEs to MU-MIMO groups with other UEs that can share interference assistance information.

[0084] In some respects, network nodes may send instructions for assignment to MU-MIMO groups. In other respects, network nodes may indicate one or more parameters associated with MU-MIMO groups, such as DMRS sequences and / or CDM parameters.

[0085] In some examples, the UE may send an indication of the type of suppression supported by the UE. In some aspects, the UE may indicate support for suppression, the UE's receiver type (e.g., UE category, degraded UE, or repeater UE, etc.), and / or the configuration of the UE's operating mode, etc. In some aspects, the network node may configure the UE's operating mode at least in part based on the indication of support and / or receiver type (e.g., in the context of interference assistance information).

[0086] In some aspects, network nodes can indicate assignments to MU-MIMO groups. For example, a network node can send indications (e.g., implicit indications of MU-MIMO groups) of parameters associated with a MU-MIMO group (e.g., DMRS sequences, CDM information, and / or beam information). In some aspects, network nodes can indicate explicit indications of MU-MIMO groups. In some aspects, explicit indications of MU-MIMO groups can be associated with one or more parameters of the MU-MIMO group known to the UE (e.g., communication protocols and / or configurations indicated by the network node). In some aspects, network nodes can accept a UE into a MU-MIMO group via indications such as a pre-decoded matrix indicator (PMI) report.

[0087] In some respects, the network node may configure the UE to receive multicast messages associated with MU-MIMO groups and / or to receive or send reports associated with MU-MIMO messages. For example, the UE may be configured to receive multicast messages indicating configuration information and / or DCI, etc. Additionally or alternatively, the UE may be configured to send feedback or other information related to the generation of interference assistance information and / or the assignment to MU-MIMO groups to the network node.

[0088] The UE can receive interference assistance information from the network node while being assigned to an MU-MIMO group. In some aspects, the interference assistance information can be shared with all UEs in the MU-MIMO group. In some aspects, the UE can send an acknowledgment (ACK) associated with the reception of the interference assistance information. In some aspects, the UE can provide additional feedback to the network node to assist in potential reassignment to different MU-MIMO groups. For example, the UE can provide indications of one or more parameters indicating successful noise cancellation or suppression, based at least in part on the interference assistance information.

[0089] Figure 5 This is a diagram illustrating example 500 associated with interference-aiding information used for MU-MIMO groups, according to this disclosure. Figure 5 As shown, network nodes (e.g., network nodes 110, CU, DU, and / or RU) can communicate with a UE (e.g., UE 120). In some aspects, the network nodes and UEs can be part of a wireless network (e.g., wireless network 100). The UE and network nodes can... Figure 5 The operation shown has been performed after a wireless connection has been established. Figure 5 As further shown, network nodes can communicate using MU-MIMO groups (such as a first MU-MIMO group and a second MU-MIMO group). In some aspects, a UE can be assigned to a first MU-MIMO group and / or a second MU-MIMO group. In other aspects, a UE can be assigned to one or more additional MU-MIMO groups (e.g., a third MU-MIMO group and / or a fourth MU-MIMO group, etc.).

[0090] As shown by reference numeral 505 in the attached figure, a network node can send configuration information, and a UE can receive configuration information. In some aspects, the UE can receive configuration information via one or more of the following: RRC signaling, one or more Media Access Control (MAC) control elements (CE) and / or DCI, etc. In some aspects, the configuration information may include indications of one or more configuration parameters for the UE to select (e.g., those known to the UE and / or previously indicated by the network node or other network device) and / or explicit configuration information for the UE to configure itself, etc.

[0091] In some aspects, the configuration information may instruct the UE to send one or more types of indications regarding interference assistance information and / or suppression supported by the UE. In some aspects, the configuration information may instruct the UE to send indications regarding the UE's receiver type (e.g., UE category, repeater mobile terminal, user-based UE, and / or degraded UE, etc.).

[0092] In some aspects, configuration information may indicate the delivery mode and / or format associated with the network node transmission of interference-aiding information. For example, configuration information may indicate time and frequency resources that can carry configuration information, the message type carrying interference-aiding information (e.g., DCI), the periodicity of transmission of interference-aiding information, the configuration for providing feedback and / or ACKs associated with interference-aiding information, and / or the periodicity for updating interference-aiding information, etc. In some aspects, configuration information may indicate the operating mode associated with one or more parameters related to interference-aiding information and / or the feedback for interference-aiding information (e.g., as described herein).

[0093] The UE can configure itself, at least in part, based on configuration information. In some respects, the UE can be configured to perform one or more of the operations described herein, at least in part, based on configuration information.

[0094] As shown by reference numeral 510 in the attached figure, the UE can send a capability report, and the network node can receive the capability report. In some aspects, the capability report can indicate the UE's support for one or more interference assistance information and / or noise suppression using interference assistance information (e.g., positive support or no support). In some aspects, the capability report can indicate the UE's receiver type.

[0095] In some respects, the operations associated with reference numerals 505 and 510 may be performed in a different order. For example, one or more operations described in conjunction with reference numeral 505 may be performed, followed by one or more operations described in conjunction with reference numeral 510, followed by one or more additional operations described in conjunction with reference numeral 505 (e.g., configuration of the UE's operating mode).

[0096] As shown by reference numeral 515 in the attached figure, the UE may receive an instruction for assignment to a MU-MIMO group and / or interference information, while the network node may transmit the instruction for assignment to a MU-MIMO group and / or interference information. In some aspects, the UE may receive an instruction for assignment and then may receive interference assistance information (e.g., at least in part based on association with a MU-MIMO group). For example, at least in part based on receiving an assignment, the UE may register to receive multicast communication of the MU-MIMO group, through which the UE may receive interference assistance information. In some aspects, the UE may receive interference assistance information at least in part based on transmitting an instruction for support for one or more interference cancellation operations associated with the interference assistance information.

[0097] In some respects, network nodes can indicate MU-MIMO groups using implicit indications (such as indications to PMI). In other respects, network nodes can send indications to MU-MIMO groups at the granularity of an activity window (e.g., MU-MIMO group assignments last for the entire activity window). For example, at the start of an activity window, a UE can receive an indication as part of a first MU-MIMO group. The UE can register to multicast messages and / or reports associated with the first MU-MIMO group.

[0098] In some aspects, interference assistance information may indicate one or more parameters for the UE to eliminate or suppress noise in the environment that may otherwise interfere with communication from network nodes. For example, interference assistance information may indicate a matrix to be applied to signal sampling that can suppress or eliminate noise. In some aspects, the UE may receive interference assistance information in each time slot of downlink communication to the UE. In some aspects, the UE and other UEs in the first MU-MIMO group may receive interference assistance information via multicast messages associated with the first MU-MIMO group.

[0099] In some respects, the UE can receive interference assistance information via DCI. For example, the UE can receive interference assistance information via a single DCI message or via multiple DCI messages.

[0100] In some aspects, the DCI can be configured via auxiliary information, such as indicated in the information element of the RRC message. In other aspects, the UE configuration can indicate the DCI reception information (e.g., an indication of blind detection using the DCI). For example, the configuration can indicate the group common search space set, MU group radio network temporary identifier (RNTI) scrambling, the index of MIMO group information within the DCI (e.g., information that can be indicated via dynamic signaling, such as the DCI), and / or the size of the DCI used for blind decoding (e.g., in bits), etc.

[0101] In some respects, DCI may include the same DMRS sequence, different DMRS sequences, modulated or unmodulated, based at least in part on interference-aided information (e.g., at least in part on UEs in MU-MIMO groups).

[0102] In some aspects, a single DCI message may include interference assist information for a first MU-MIMO group and interference assist information for the MU-MIMO group (e.g., where interference assist information for different MU-MIMO groups is indexed within the DCI). In this case, all UEs in the first MU-MIMO group and the second MU-MIMO group can be reconfigured to receive a DCI including interference assist information (IAI) for each group. Additionally or alternatively, the network node may send a first DCI message including interference assist information for the first MU-MIMO group and a second DCI message including interference assist information for the second MU-MIMO group. In some aspects, the first UE may be configured to receive only the first interference assist information in the interference assist information, and the second UE may be configured to receive only the second interference assist information in the interference assist information. In some aspects, a third UE (e.g., located near the edge of the first MU-MIMO group and the second MU-MIMO group (e.g., physically close to the boundary or having interference assist feedback similar to that of the first MU-MIMO group and the second MU-MIMO group (such as the average or near-average of the MU-MIMO group)).

[0103] In some aspects, interference assistance information for the first MU-MIMO group may include a DMRS configuration indicator (e.g., DMRS...). config (i) The DMRS configuration indicator includes several bits (e.g., 2 bits) indicating the DMRS configuration for the first MU-MIMO group. For example, '0'(1,1), '1'(1,2), '2'(2,1), and '3'(2,2) are used to provide N DMRS = 4 / 8 / 6 / 12. Interference assistance information may include indications of the DMRS bitmap (e.g., DMRS...). bitmap (i) The DMRS bitmap includes several bits (e.g., 4 / 6 / 8 / 12 bits) for switching the DMRS used by all UEs in the first MU-MIMO group. If the interference assist information includes modulation, the interference assist information may be included in the DMRS. bitmap (i) cycles through k DMRS to provide modulation (k) (e.g., using 3 bits).

[0104] In some respects, DCI can have capacity limitations for L MU-MIMO groups. For example, ≤128 bits. In the absence of modulation, for all MIMO groups, when N...DMRS When N = 8, L ≤ 12. In the unmodulated case, for all MIMO groups, when N... DMRS When N = 12, L ≤ 9. In the case of modulation, for all MIMO groups, when N... DMRS = 8 and using 7 DMRS, L ≤ 4. In the case of modulation, for all MIMO groups, when N DMRS = 12 and using 12 DMRS, L ≤ 2. As shown in the figure, a smaller number of supported MIMO groups in the DCI can use a larger number of DCIs, consuming control channel elements (CCEs) and / or other resources used for DCI scheduling data.

[0105] In some aspects, network nodes can support aggregated UE-specific dimensions. For example, multiple MIMO groups (e.g., single-user or multi-user MIMO groups) can be spatially arranged, where beamforming achieves spatial separation. Applying different DMRS sequences to different MIMO groups can provide additional DMRS separation. In this way, UEs in MU-MIMO groups can use the flexible message transmission and reception envelope of the DCI described herein to receive DMRS sequences for each MIMO group (e.g., for intra-group and inter-group interference cancellation).

[0106] In the example, two spatially separated MIMO groups can each use eight layers. A first UE can be assigned to the first MIMO group (e.g., the first MIMO group has good spatial separation from the second MIMO group), and this first UE has interference assist information for the first MIMO group. A second UE can be assigned to the second MIMO group (e.g., the second MIMO group has good spatial separation from the first MIMO group), and this second UE has interference assist information for the second MIMO group. A third UE can be assigned to both MIMO group 1 and MIMO group 2 (with poor spatial separation between the first MIMO group and the second MIMO group), and this third UE has interference assist information for both the first MIMO group and the second MIMO group.

[0107] In some aspects, the DCI including interference assistance information for MIMO group i may include a scrambling ID(i) associated with a specific MIMO group. For example, the scrambling ID(i) may include an N indicating each MIMO group i. ID Several bits (e.g., 16 bits). The DCI including interference assist information may include several bits (e.g., 2 bits) of DMRS indicating the DMRS configuration in the MU-MIMOi. config (i).

[0108] In some aspects, the DCI may include UE j included in MIMO group i on a loop. In some aspects, the DCI may include antenna port information (API) (j) indicating the DMRS AP and CDM (e.g., 4 / 5 / 6 bits), DMRS sequence initialization (j) indicating the nSCID (e.g., 1 bit), and / or, if the DCI includes modulation using several bits (e.g., 3 bits), an indication of the modulation used.

[0109] In some respects, DCI may have capacity limitations for L MU-MIMO groups, each group comprising J UEs. For example, ≤128 bits. In the unmodulated example, N DMRS = 8, and 2 UEs constitute all MIMO groups, L ≤ 4 (e.g., 4 spatially separated MIMO groups). In the example with modulation, N DMRS =8, and 4 UEs constitute all MIMO groups, L ≤ 2 (e.g., 2 spatially separated MIMO groups).

[0110] As shown by reference numeral 520 in the attached figure, the UE may send an ACK associated with an instruction to an MU-MIMO group. Additionally or alternatively, the UE may send an ACK associated with interference assistance information.

[0111] In some aspects, the UE may receive an instruction for assignment to a MU-MIMO group and may send a first ACK associated with the assignment. Once assigned to a MU-MIMO group, the UE may receive interference assist information and may send a second ACK associated with the interference assist information. In some aspects, the UE may receive the instruction for assignment only at the start of the active window and may receive interference assist information for each time slot.

[0112] As shown by reference numeral 525, a UE can receive one or more communications and a network node can send one or more communications, at least in part, based on interference assist information. Also as shown by reference numeral 525, other UEs in the first MU-MIMO group can receive communications, at least in part, based on interference assist information.

[0113] In some aspects, the UE may receive communication within a set of time and frequency resources associated with a first MU-MIMO group (e.g., associated with interference-assisted feedback). In some aspects, the communication may include multicast messages sent to UEs in the first MU-MIMO group.

[0114] Communication may include PDSCH communication or other data channel communication. The UE may use interference-aiding information to suppress noise on the channel associated with the communication, and may demodulate and decode the communication with improved accuracy based at least in part on noise suppression. In this way, the UE can reduce the communication error rate, which can save communication, power, network and / or computing resources that might otherwise be consumed by detecting and correcting communication errors.

[0115] In some respects, network nodes can at least partially rely on the UE having interference-aiding information to transmit communications with improved spectral efficiency. For example, network nodes can at least partially rely on... UE support The expectation of improved interference reduction and / or suppression associated with received communication is to increase the MCS of the communication. The UE can receive communication and perform enhanced reception of the communication. For example, the UE can use interference assistance information to reduce and / or suppress interference from the communication.

[0116] As shown by reference numeral 530 in the attached figure, the UE may transmit interference-assisted feedback. In some aspects, the interference-assisted feedback is at least partially based on interference-assisted information to indicate one or more parameters for interference cancellation or suppression.

[0117] In some aspects, the UE may send interference-assisted feedback for each time slot and / or each communication. In some aspects, the UE may send interference-assisted feedback within each time slot or after several time slots. For example, the UE may send an ACK for interference-assisted information in each time slot in which the UE receives interference-assisted information (e.g., first interference-assisted feedback). In some aspects, interference-assisted feedback may be split among multiple transmissions on multiple time slots. For example, the UE may not only send the same interference-assisted feedback as the report on the associated time slot, but may also send large feedback messages transmitted on consecutive time slots (e.g., feedback indicating noise on the first time slot, feedback indicating first type of interference on the second time slot, and / or feedback indicating second type of interference on the third time slot).

[0118] In some aspects, the UE may transmit an indication of observed noise and / or noise suppression (e.g., a second interference-aided feedback). The UE may provide interference-aided feedback (e.g., a second interference-aided feedback) after several time slots (e.g., one or more time slots). In some aspects, interference-aided information transmitted after several time slots may include an indication of interference measured or otherwise observed. The indication may be based at least in part on the averaging of one or more parameters associated with interference and / or interference suppression over the several time slots.

[0119] As shown by reference numeral 535 in the attached figure, the UE may receive an indication of an updated assignment to a second MU-MIMO group and / or updated interference assistance information, and the network node may send the indication of the updated assignment to the second MU-MIMO group and / or updated interference assistance information. In some aspects, the UE may receive an indication of an updated assignment and then may receive updated interference assistance information (e.g., at least in part based on association with the second MU-MIMO group). For example, based at least in part on receiving the updated assignment, the UE may register to receive multicast communication of the second MU-MIMO group, through which the UE may receive updated interference assistance information.

[0120] In some respects, network nodes can use implicit indications (such as indications to the PMI) to indicate updated MU-MIMO group assignments. In other respects, network nodes can send indications of updated MU-MIMO group assignments at the granularity of an active window. UEs can register to multicast messages associated with a second MU-MIMO group and / or reports associated with a second MU-MIMO group.

[0121] In some respects, the UE and other UEs in the second MU-MIMO group can receive interference assistance information via multicast messages associated with the second MU-MIMO group.

[0122] As indicated by reference numeral 540 in the attached figure, the UE may send an ACK associated with an indication of an updated assignment to a second MU-MIMO group. Additionally or alternatively, the UE may send an ACK associated with updated interference assistance information.

[0123] In some aspects, the UE may receive an indication of an updated assignment to a second MU-MIMO group and may send a first ACK associated with the assignment. Once assigned to the second MU-MIMO group, the UE may receive updated interference assist information and may send a second ACK associated with the updated interference assist information. In some aspects, the UE may receive an indication of an updated assignment only at the start of the activity window and may receive updated interference assist information for each time slot.

[0124] As shown by reference numeral 545, a UE can receive one or more communications, and a network node can send one or more communications, at least in part, based on the updated interference assist information. Also as shown by reference numeral 545, other UEs in the second MU-MIMO group can receive communications, at least in part, based on the updated interference assist information.

[0125] In some aspects, the UE may receive communication via a set of time and frequency resources associated with a second MU-MIMO group. This set of time and frequency resources associated with the second MU-MIMO group may differ from the set of time and frequency resources associated with the first MU-MIMO group. In some aspects, the communication may include multicast messages sent to the UE in the second MU-MIMO group.

[0126] At least in part, based on providing interference-aided feedback, interference-aided information can be improved by supporting the assignment of updated MU-MIMO groups and associated interference-aided information. Based at least in part on the improved interference-aided information, the UE can save power, processing, network, and / or communication resources that might otherwise have been consumed by detecting and / or correcting errors associated with outdated interference-aided information (e.g., associated with suboptimal MU-MIMO group assignments). Additionally or alternatively, based at least in part on the improved interference-aided information, the UE and network nodes can communicate using improved spectral efficiency, cell throughput, and / or cell coverage, etc.

For example, network nodes (e.g., using...) Figure 9 The depicted transmitting component 904 and / or communication manager 906 can transmit communications to the UE, at least in part, based on interference-assisted feedback, within a set of time and frequency resources associated with the second MU-MIMO group, as described above.

In some aspects, device 800 includes a receiving component 802, a transmitting component 804, and / or a communication manager 806 that can communicate with each other (e.g., via one or more buses and / or one or more other components).
