Channel state information (CSI) reporting for one or both of private message (P-message) or common message (C-message)

Abstract

Some aspects of the present disclosure relate to channel state information (CSI) reporting for one or both of a private message (p-message) or a public message (c-message). In some aspects, a user equipment (UE) can receive a signal including a p-message associated with the UE and c-messages associated with the UE and at least one other UE. The UE can transmit a measurement report indicating one or both of a first CSI associated with the p-message or a second CSI associated with the c-message.

Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly to reporting of channel state information (CSI) within wireless communication systems.

[0002] Related technical description

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. A wireless multiple access communication system may include multiple base stations or network access nodes, each of which simultaneously supports communication of multiple communication devices (which may be referred to as user equipment (UE) in other aspects). These systems may be able to support communication with multiple UEs by sharing available system resources (such as time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM).

[0004] As the number of wireless communication devices increases, signaling within the wireless communication system may be associated with noise and interference, which may reduce the performance of the wireless communication system. In order to reduce the amount of signaling sent and improve performance, the wireless communication system may use rate division (RS) or rate division multiple access (RSMA) technology, where the signal may include a private message (p-message) and a public message (c-message). The p-message may include data associated with one UE, and the c-message may include data associated with multiple UEs. By including p-messages and c-messages in the signal, the amount of redundant signaling can be reduced. In addition, in some specific implementations, the UE receiving the signal can use successive interference cancellation (SIC) to decode the p-message based on the c-message, which can improve the decoding performance of the UE.

[0005] In some implementations, the use of RS or RSMA techniques may increase the complexity, cost, or overhead associated with a wireless communication system. For example, in a beamforming implementation, a p-message and a c-message may be associated with different beams, which may enable one UE to receive a p-message and multiple UEs to receive a c-message. In such an example, a base station sending a signal may need to separately manage the beams for the c-message and for each p-message, which may increase the complexity, cost, or overhead associated with a wireless communication system. Summary of the invention

[0006] The following summarizes some aspects of the present disclosure to provide a basic understanding of the technology discussed. This summary is not an extensive review of all expected features of the present disclosure, and is neither intended to identify key or important elements of all aspects of the present disclosure, nor to delineate the scope of any or all aspects of the present disclosure.

[0022] 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 given throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings of this article, it will be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether the aspect is implemented independently of any other aspect of the present disclosure or implemented 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 a device or method practiced using other structures, functionality, or structure and functionality other than the various aspects of the disclosure set forth herein. Any aspect of the present disclosure disclosed herein may be embodied by one or more elements of a claim.

[0023] Some aspects of the present disclosure relate to channel state information (CSI) reporting for one or both of a private message (p-message) or a public message (c-message). In some aspects, a user equipment (UE) may receive a signal including a p-message associated with the UE and a c-message associated with the UE and at least one other UE. The UE may determine one or both of a first CSI associated with the p-message or a second CSI associated with the c-message. In some examples, the UE may determine the first CSI and the second CSI based on decoding of the signal. For example, the UE may determine the first CSI and the second CSI based on a reference signal associated with the signal, such as a demodulation reference signal (DMRS) or a CSI reference signal (CSI-RS) used to decode the signal. Alternatively or in addition, the UE may determine the first CSI and the second CSI based on a value determined during decoding of the signal, such as a log-likelihood ratio (LLR) value determined during decoding of the signal.

[0024] The UE may send a measurement report to the base station indicating one or more of the first CSI, the second CSI, or a metric representing a combination of the first CSI and the second CSI, such as an average of parameters associated with the first CSI and the second CSI. In some examples, the base station 105 may adjust one or more parameters based on the measurement report. For example, the base station may change one or more pre-decoders to reduce a block error rate (BLER) associated with a p-message, reduce a BLER associated with a c-message, or both.

[0025] Specific implementations of the subject matter described in the present disclosure may be implemented to achieve one or more of the following potential advantages. For example, by reporting one or more of the first CSI, the second CSI, or the metric, the base station may independently determine or adjust one or more parameters associated with the p-message, the c-message, or both. By independently adjusting one or more parameters, the base station may independently reduce the BLER metrics associated with the p-message and the c-message. Thus, the reception of p-messages and c-messages within a wireless communication system may be improved, which in some cases may reduce the number of negative acknowledgement (NACK) messages and retransmissions.

[0026] In various implementations, the techniques and apparatus may be used in wireless communication networks, such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single carrier FDMA (SC-FDMA) networks, LTE networks, GSM networks, fifth generation (5G) or new radio (NR) networks (sometimes referred to as "5G NR" networks, systems, or devices), and other communication networks. As described herein, the terms "network" and "system" may be used interchangeably. In some implementations, two or more wireless communication systems (also referred to as wireless communication networks) may be configured to provide or participate in authorized shared access between the two or more wireless communication systems.

[0027] A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband-CDMA (W-CDMA) and Low Chip Rate (LCR). CDMA2000 covers IS-2000, IS-95, and IS-856 standards.

[0028] TDMA networks can implement radio technologies such as Global System for Mobile Communications (GSM). 3GPP defines standards for GSM Evolution (Enhanced Data Rates for GSM Evolution) Radio Access Network (RAN) (also denoted as GERAN). GERAN is a radio component of GSM or GSM EDGE together with a network that combines a base station (e.g., Ater and Abis interfaces, etc.) and a base station controller (e.g., interfaces, etc.). The radio access network represents a component of the GSM network, through which phone calls and packet data are routed from the public switched telephone network (PSTN) and the Internet to subscriber phones (also referred to as user terminals or user equipment (UE)) and from subscriber phones to the PSTN and the Internet. The network of a mobile phone operator may include one or more GERANs, which may be coupled to UTRAN in the case of a UMTS / GSM network. Additionally, the operator network may include one or more LTE networks, or one or more other networks. Various network types may use different radio access technologies (RATs) and radio access networks (RANs).

[0029] OFDMA network can realize radio technology such as Evolved UTRA (E-UTRA), IEEE 802.11, IEEE 802.16, IEEE802.20, Flash OFDM, etc. UTRA, E-UTRA and GSM are part of Universal Mobile Telecommunication System (UMTS). Specifically, Long Term Evolution (LTE) is a UMTS version using E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documents provided by an organization named "3rd Generation Partnership Project" (3GPP), while cdma2000 is described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). These radio technologies and standards are known or under development. For example, 3GPP is a collaboration between telecommunication association groups to define globally applicable third generation (3G) mobile phone specifications. 3GPP Long Term Evolution (LTE) is a 3GPP plan to improve the Universal Mobile Telecommunication System (UMTS) mobile phone standard. 3GPP can define the specifications of next generation mobile networks, mobile systems and mobile devices. The present disclosure may describe certain aspects with reference to LTE, 4G, 5G or NR technology; however, the description is not intended to be limited to a particular technology or application, and one or more aspects described with reference to one technology may be understood to be applicable to another technology. In fact, one or more aspects of the present disclosure relate to shared access to wireless spectrum between networks using different radio access technologies or radio air interfaces.

[0030] 5G networks are expected to have diverse deployments, diverse spectrum, and diverse services and devices that can be implemented using a unified air interface based on OFDM. To achieve these goals, in addition to developing new radio technologies for 5G NR networks, further enhancements to LTE and LTE-A are also considered. 5G NR will be able to scale to (1) provide coverage to the massive Internet of Things (IoT) with ultra-high density (such as about 1M nodes / km2), ultra-low complexity (such as about tens of bits / second), ultra-low energy (such as about 10+ years battery life), and provide deep coverage with the ability to reach challenging locations; (2) include mission-critical control with strong security to protect sensitive personal, financial, or classified information, ultra-high reliability (such as about 99.9999% reliability), ultra-low latency (such as about 1 millisecond (ms)), and users with a wide range of mobility or lack of mobility; and (3) provide coverage with enhanced mobile broadband (including extremely high capacity (such as about 10Tbps / km2), extremely high data rates (such as multi-Gbps rates, 100+Mbps user experience rates), and deep awareness with advanced discovery and optimization).

[0031] 5G NR devices, networks, and systems can be implemented to use optimized OFDM-based waveform features. These features may include scalable parameter sets and transmission time intervals (TTIs); a common flexible framework that effectively multiplexes services and features using dynamic, low-latency time division duplex (TDD) or frequency division duplex (FDD) designs; and advanced wireless technologies such as massive multiple-input multiple-output (MIMO), robust millimeter wave (mmWave) transmission, advanced channel decoding, and device-centric mobility. The scalability of parameter sets in 5GNR and the scaling of subcarrier spacing can efficiently address various services operating across different spectrums and different deployments. For example, in various outdoor and macro coverage deployments of less than 3GHz FDD or TDD implementations, the subcarrier spacing may appear at 15kHz on bandwidths such as 1MHz, 5MHz, 10MHz, 20MHz, etc. For other various outdoor and small cell coverage deployments of TDD greater than 3GHz, the subcarrier spacing may appear at 30kHz on 80MHz or 100MHz bandwidths. For various other indoor broadband implementations, using TDD on the unlicensed portion of the 5GHz band, the subcarrier spacing may occur at 60kHz over a 160MHz bandwidth. Finally, for various deployments transmitting with mmWave components at 28GHz TDD, the subcarrier spacing may occur at 120kHz over a 500MHz bandwidth.

[0032] 5G NR's scalable parameter sets facilitate scalable TTIs for diverse latency and quality of service (QoS) requirements. For example, shorter TTIs can be used for low latency and high reliability, while longer TTIs can be used for higher spectral efficiency. Efficient multiplexing of long and short TTIs allows transmission to start on symbol boundaries. 5G NR also anticipates a self-contained integrated subframe design where uplink or downlink scheduling information, data, and acknowledgments are in the same subframe. The self-contained integrated subframe supports communications in unlicensed or contention-based shared spectrum, and adaptive uplink or downlink can be flexibly configured on a per-cell basis to dynamically switch between uplink and downlink to meet current business needs.

[0033] For clarity, certain aspects of the devices and techniques may be described below with reference to example 5G NR implementations or in a 5G-centric manner, and 5G terminology may be used as illustrative examples in portions of the description below; however, the description is not intended to be limited to 5G applications.

[0034] Furthermore, it should be understood that in operation, a wireless communication network adapted according to the concepts herein can operate using any combination of licensed spectrum or unlicensed spectrum depending on load and availability. Therefore, it will be apparent to one of ordinary skill in the art that the systems, devices, and methods described herein can be applied to other communication systems and applications beyond the specific examples provided.

[0035] Figure 1 1 is a block diagram illustrating details of an example wireless communication system. The wireless communication system may include a wireless network 100. For example, the wireless network 100 may include a 5G wireless network. As will be appreciated by those skilled in the art, Figure 1 The components appearing in may have related counterparts in other network arrangements, including, for example, cellular network arrangements and non-cellular network arrangements (such as device-to-device, ad-hoc, or ad-hoc network arrangements, etc.).

[0036] Figure 1 The wireless network 100 shown includes multiple base stations 105 and other network entities. A base station may be a station that communicates with a UE and may be referred to as an evolved Node B (eNB), a next generation eNB (gNB), an access point, etc. Each base station 105 may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the specific geographic coverage area of ​​a base station or a base station subsystem serving the coverage area, depending on the context in which the term is used. In a specific implementation of the wireless network 100 herein, the base station 105 may be associated with the same operator or different operators, such as the wireless network 100 may include multiple operator wireless networks. Additionally, in a specific implementation of the wireless network 100 herein, the base station 105 may use one or more frequencies (such as one or more frequency bands in a licensed spectrum, an unlicensed spectrum, or a combination thereof) in the same frequency as a neighboring cell to provide wireless communication. In some examples, a separate base station 105 or UE115 may be operated by more than one network operating entity. In some other examples, each base station 105 and UE115 may be operated by a single network operating entity.

[0037] A base station may provide communication coverage for a macro cell or a small cell (e.g., a pico cell or a femto cell) or other type of cell. A macro cell generally covers a relatively large geographic area (such as a radius of several kilometers) and may allow unrestricted access by UEs that have a service subscription with a network provider. A small cell (such as a pico cell) will generally cover a relatively small geographic area and may allow unrestricted access by UEs that have a service subscription with a network provider. A small cell (such as a femto cell) will generally also cover a relatively small geographic area (such as a residence) and, in addition to unrestricted access, may provide restricted access to UEs associated with the femto cell (such as UEs in a closed subscriber group (CSG), UEs of users in the residence, and so on). A base station for a macro cell may be referred to as a macro base station. A base station for a small cell may be referred to as a small cell base station, a pico base station, a femto base station, or a home base station. In Figure 1 In the example shown in FIG. 1 , base stations 105d and 105e are conventional macro base stations, while base stations 105a-105c are macro base stations enabled with one of 3-dimensional (3D), full-dimensional (FD), or massive MIMO. Base stations 105a-105c utilize their higher-dimensional MIMO capabilities to increase coverage and capacity using 3D beamforming in both elevation and azimuth beamforming. Base station 105f is a small cell base station, which can be a home node or a portable access point. The base station can support one or more cells, such as two cells, three cells, four cells, and so on.

[0038] Wireless network 100 may support synchronous or asynchronous operation. For synchronous operation, base stations may have similar frame timing, and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, base stations may have different frame timing, and transmissions from different base stations may not be aligned in time. In some cases, the network may be enabled or configured to handle dynamic switching between synchronous or asynchronous operation.

[0039] UE 115 is dispersed throughout the wireless network 100, and each UE may be stationary or mobile. It should be understood that although mobile devices are generally referred to as user equipment (UE) in the standards and specifications promulgated by 3GPP, such devices may be additionally or additionally referred to as mobile stations (MS), subscriber stations, mobile units, subscriber units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals (AT), mobile terminals, wireless terminals, remote terminals, handsets, terminals, user agents, mobile clients, clients, or some other suitable terminology by those skilled in the art. In this document, a "mobile" device or UE does not necessarily have the ability to move and may be stationary. Some non-limiting examples of mobile devices, such as may include specific implementations of one or more of the UEs 115, include mobile stations, cellular (mobile) phones, smart phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, laptops, personal computers (PCs), notebooks, netbooks, smartbooks, tablets, and personal digital assistants (PDAs). The mobile device may additionally be an "Internet of Things" (IoT) or "Internet of Everything" (IoE) device, such as a car or other transportation vehicle, a satellite radio, a global positioning system (GPS) device, a global navigation satellite system (GNSS) device, a logistics controller, a drone, a multi-rotor helicopter, a quad-rotor helicopter, a smart energy or security device, a solar panel or solar array, city lighting, tap water or other infrastructure; industrial automation and enterprise equipment; consumer and wearable devices, such as glasses, wearable cameras, smart watches, health or fitness trackers, mammal implantable devices, gesture tracking devices, medical devices, digital audio players (such as MP3 players), cameras or game consoles, etc.; and digital home or smart home devices, such as home audio, video and multimedia devices, appliances, sensors, vending machines, smart lighting, home security systems or smart meters, etc. In one aspect, the UE may be a device including a universal integrated circuit card (UICC). In another aspect, the UE may be a device that does not include a UICC. In some aspects, a UE that does not include a UICC may be referred to as an IoE device. Figure 1 The UEs 115a-115d of the illustrated implementation are examples of mobile smartphone-type devices accessing the wireless network 100. A UE may be a machine specifically configured for connected communications, including machine type communications (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc. Figure 1 The UEs 115e-115k shown are examples of various machines configured for communications accessing the 5G network 100.

[0040] A mobile device, such as UE 115, may be able to communicate with any type of base station, whether macro, pico, femto, relay, etc. Figure 1 In the figure, the communication link (represented as a lightning bolt) indicates the wireless transmission between the UE and the serving base station (the serving base station is the base station designated to serve the UE on the downlink or uplink), or the expected transmission between the base stations, and the backhaul transmission between the base stations. The backhaul communication between the base stations of the wireless network 100 can occur using wired or wireless communication links.

[0041] In operation of the 5G network 100, base stations 105a-105c use 3D beamforming and coordinated spatial techniques, such as coordinated multipoint (CoMP) or multi-connectivity, to serve UE 115a and UE 115b. Macro base station 105d performs backhaul communications with base stations 105a-105c and small cell base station 105f. Macro base station 105d also transmits multicast services that are subscribed to and received by UE 115c and UE 115d. Such multicast services may include mobile TV or streaming video, or may include other services for providing community information, such as weather emergencies or alerts, such as Amber alerts or gray alerts.

[0042] The wireless network 100 of the specific implementation supports mission-critical communications with ultra-reliable and redundant links for mission-critical devices (e.g., UE 115e as a drone). The redundant communication links with UE 115e include from macro base stations 105d and 105e, and small cell base station 105fo. Other machine-type devices (such as UE 115f (thermometer), UE 115g (smart meter), and UE 115h (wearable device)) can communicate directly with base stations (such as small cell base station 105f and macro base station 105e) through the wireless network 100, or communicate through the wireless network in a multi-hop configuration by communicating with another user equipment that relays its information to the network (such as UE 115f communicating temperature measurement information to smart meter UE 115g, which is reported to the network through small cell base station 105f). The 5G network 100 may provide additional network efficiency through dynamic, low-latency TDD or FDD communications, such as in a vehicle-to-vehicle (V2V) mesh network between UEs 115i-115k communicating with a macro base station 105e.

[0043] Figure 2 1 is a block diagram conceptually illustrating an example design of a base station 105 and a UE 115. The base station 105 and the UE 115 may be Figure 1 For a restricted association scenario (as mentioned above), the base station 105 may be Figure 1105f in the small cell base station 105f, and UE 115 may be UE 115c or UE 115d operating in the service area of ​​​​the base station 105f. In order to access the small cell base station 105f, the UE 115 will be included in the accessible UE list of the small cell base station 105f. In addition, the base station 105 may be some other type of base station. Figure 2 As shown in FIG. 1 , the base station 105 may be equipped with antennas 234a through 234t, and the UE 115 may be equipped with antennas 252a through 252r, for facilitating wireless communication.

[0044] At the base station 105, the transmit processor 220 may receive data from the data source 212 and control information from the processor 240. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid ARQ (automatic repeat request) indicator channel (PHICH), a physical downlink control channel (PDCCH), an enhanced physical downlink control channel (EPDCCH), or an MTC physical downlink control channel (MPDCCH), etc. The data may be for a PDSCH, etc. The transmit processor 220 may process (such as, encode and symbol map) the data and the control information, respectively, to obtain data symbols and control symbols. Additionally, the transmit processor 220 may generate reference symbols, such as reference symbols for a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), and a cell-specific reference signal. The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing on data symbols, control symbols, or reference symbols (if applicable), and may provide output symbol streams to modulators (MODs) 232a to 232t. For example, the spatial processing performed on the data symbols, control symbols, or reference symbols may include pre-decoding. Each modulator 232 may process a corresponding output symbol stream (such as for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may additionally or alternatively process the output sample stream to obtain a downlink signal. For example, to process the output sample stream, each modulator 232 may convert the output sample stream into an analog, amplify, filter, and up-convert the output sample stream to obtain a downlink signal. The downlink signals from modulators 232a to 232t may be transmitted via antennas 234a to 234t, respectively.

[0045] At the UE 115, antennas 252a to 252r may receive downlink signals from the base station 105 and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition a corresponding received signal to obtain input samples. For example, to condition a corresponding received signal, each demodulator 254 may filter, amplify, downconvert, and digitize a corresponding received signal to obtain input samples. Each demodulator 254 may further process the input samples (such as for OFDM, etc.) to obtain received symbols. The MIMO detector 256 may obtain received symbols from the demodulators 254a to 254r, perform MIMO detection on the received symbols when necessary, and provide detected symbols. The receive processor 258 may process the detected symbols, provide decoded data for the UE 115 to the data sink 260, and provide decoded control information to the processor 280. For example, to process the detected symbols, the receive processor 258 may demodulate, deinterleave, and decode the detected symbols.

[0046] On the uplink, at the UE 115, a transmit processor 264 may receive and process data from a data source 262, such as for a physical uplink shared channel (PUSCH), and control information from a processor 280, such as for a physical uplink control channel (PUCCH). Additionally, the transmit processor 264 may generate reference symbols for reference signals. The symbols from the transmit processor 264 may be pre-decoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a through 254r, such as for SC-FDM, etc., and transmitted to the base station 105. At the base station 105, uplink signals from the UE 115 may be received by antennas 234, processed by demodulators 232, detected by MIMO detectors 236, if applicable, and further processed by receive processors 238 to obtain decoded data and control information transmitted by the UE 115. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a processor 240.

[0047] Processors 240 and 280 may direct the operation at base station 105 and UE 115, respectively. Processor 240 or other processors and modules at base station 105 or processor 280 or other processors and modules at UE 115 may perform or direct the execution of various processes for the techniques described herein, such as performing or directing Figure 4 and Figure 52 and 3. The memory 242 and 282 may store data and program codes for the base station 105 and the UE 115, respectively. The scheduler 244 may schedule the UE for data transmission on the downlink or uplink.

[0048] In some cases, the UE 115 and the base station 105 may operate in a shared radio frequency spectrum band, which may include a licensed spectrum or an unlicensed spectrum (such as, based on contention). In the unlicensed frequency portion of the shared radio frequency spectrum band, the UE 115 or the base station 105 may traditionally perform a medium sensing procedure to contend for access to the spectrum. For example, the UE 115 or the base station 105 may perform a listen-before-talk or listen-before-send (LBT) procedure (such as a clear channel assessment (CCA)) before communication to determine whether the shared channel is available. CCA may include an energy detection procedure to determine whether there are any other active transmissions. For example, the device may infer that a change in the received signal strength indicator (RSSI) of the power meter indicates that the channel is occupied. Specifically, the signal power concentrated in a certain bandwidth and exceeding a predetermined noise floor may indicate another wireless transmitter. In some specific implementations, CCA may include detection of a specific sequence indicating channel use. For example, another device may send a specific preamble before sending a data sequence. In some cases, the LBT procedure may include the wireless node acting as a proxy for collisions to adjust its own backoff window based on the amount of energy detected on the channel or acknowledgment or negative acknowledgment (ACK or NACK) feedback for its own transmitted packets.

[0049] Figure 3 is a block diagram illustrating an example of a wireless communication system 300 that supports CSI reporting for one or both of a p-message or a c-message in accordance with some aspects of the present disclosure. The wireless communication system 300 may include one or more base stations, such as base station 105. The wireless communication system 300 may include multiple UEs, such as UE 115.

[0050] Base station 105 may include one or more processors (such as processor 240), one or more memories (such as memory 242), a transmitter 306, and a receiver 308. Processor 240 may be coupled to memory 242, to transmitter 306, and to receiver 308. In some examples, transmitter 306 and receiver 308 may include reference Figure 2 One or more components described, such as one or more of the modulator / demodulators 232a-t, the MIMO detector 236, the receive processor 238, the transmit processor 220, or the TX MIMO processor 230. In some implementations, the transmitter 306 and the receiver 308 can be integrated into one or more transceivers of the base station 105.

[0051] The transmitter 306 may be configured to transmit reference signals, synchronization signals, control information, and data to one or more other devices, and the receiver 308 may be configured to receive reference signals, control information, and data from one or more other devices. For example, the transmitter 306 may be configured to transmit signaling, control information, and data to the UE 115, and the receiver 308 may be configured to receive signaling, control information, and data from the UE 115.

[0052] In some implementations, the base station 105 may include an antenna array. The antenna array may include multiple antenna elements configured to perform wireless communications with other devices (such as with the UE 115). In some implementations, the antenna array may be configured to perform wireless communications using different beams (also referred to as antenna beams). The beams may include Tx beams and Rx beams. For illustration, the antenna array may include multiple independent antenna element sets (or subsets) (or multiple independent antenna arrays), and each antenna element set of the antenna array may be configured to communicate using different corresponding beams, which may have corresponding directions different from other beams. For example, a first antenna element set of the antenna array may be configured to communicate via a first beam having a first direction, and a second antenna element set of the antenna array may be configured to communicate via a second beam having a second direction. In other implementations, the antenna array may be configured to communicate via more than two beams. Alternatively, one or more antenna element sets of the antenna array may be configured to concurrently generate multiple beams, for example using multiple RF chains of the base station 105. Each individual set (or subset) of antenna elements may include multiple antenna elements, such as two antenna elements, four antenna elements, ten antenna elements, twenty antenna elements, or any other number of antenna elements greater than two. Although described as an antenna array, in other specific implementations, the antenna array may include or correspond to multiple antenna panels, and each antenna panel may be configured to communicate using a different corresponding beam.

[0053] UE 115 may include one or more processors (such as processor 280), memory (such as memory 282), transmitter 356, and receiver 358. Processor 280 may be coupled to memory 282, to transmitter 356, and to receiver 358. In some examples, transmitter 356 and receiver 358 may include reference Figure 2 One or more components described, such as one or more of the modulator / demodulators 254a-r, the MIMO detector 256, the receive processor 258, the transmit processor 264, or the TX MIMO processor 266. In some implementations, the transmitter 356 and the receiver 358 can be integrated into one or more transceivers of the UE 115.

[0054] The transmitter 356 may transmit reference signals, synchronization signals, control information, and data to one or more other devices, and the receiver 358 may receive reference signals, control information, and data from one or more other devices. For example, in some implementations, the transmitter 356 may transmit signaling, control information, and data to the base station 105, and the receiver 358 may receive signaling, control information, and data from the base station 105.

[0055] In some implementations, one or more of the transmitter 306, the receiver 308, the transmitter 356, or the receiver 358 may include an antenna array. The antenna array may include multiple antenna elements that perform wireless communications with other devices. In some implementations, the antenna array may use different beams (also referred to as antenna beams) to perform wireless communications. The beams may include transmit beams and receive beams. For illustration, the antenna array may include multiple independent antenna element sets (or subsets) (or multiple independent antenna arrays), and each antenna element set of the antenna array may be configured to communicate using different corresponding beams, which may have corresponding directions different from other beams. For example, a first antenna element set of the antenna array may be configured to communicate via a first beam having a first direction, and a second antenna element set of the antenna array may be configured to communicate via a second beam having a second direction. In other implementations, the antenna array may be configured to communicate via more than two beams. In some implementations, one or more antenna element sets of the antenna array may be configured to generate multiple beams concurrently, for example using multiple RF chains. The set (or subset) of antenna elements may include multiple antenna elements, such as two antenna elements, four antenna elements, ten antenna elements, twenty antenna elements, or any other number of antenna elements greater than two. Although described as an antenna array, in other specific implementations, the antenna array may include or correspond to multiple antenna panels, and each antenna panel may be configured to communicate using a different corresponding beam.

[0056] In some implementations, the UE 115 may include an antenna array. The antenna array may include multiple antenna elements configured to perform wireless communications with other devices (such as with the base station 105). In some implementations, the antenna array may be configured to perform wireless communications using different beams (also referred to as antenna beams). The beams may include a TX beam and an RX beam. For illustration, the antenna array may include multiple independent antenna element sets (or subsets) (or multiple independent antenna arrays), and each antenna element set of the antenna array may be configured to communicate using a different corresponding beam, which may have a corresponding direction different from the other beams. For example, a first antenna element set of the antenna array may be configured to communicate via a first beam having a first direction, and a second antenna element set of the antenna array may be configured to communicate via a second beam having a second direction. In other implementations, the antenna array may be configured to communicate via more than two beams. Alternatively, one or more antenna element sets of the antenna array may be configured to concurrently generate multiple beams, for example using multiple RF chains of the UE 115. Each individual set (or subset) of antenna elements may include multiple antenna elements, such as two antenna elements, four antenna elements, ten antenna elements, twenty antenna elements, or any other number of antenna elements greater than two. Although described as an antenna array, in other specific implementations, the antenna array may include or correspond to multiple antenna panels, and each antenna panel may be configured to communicate using a different corresponding beam.

[0057] In some implementations, the base station 105 may include a message combiner 302. In some implementations, the UE 115 may include a message segmenter 370. The message combiner 302 and the message segmenter 370 may be configured to process messages according to a rate division (RS) or rate division multiple access (RSMA) technique.

[0058] The wireless communication system 300 may use wireless communication channels, which may be specified by one or more wireless communication protocols, such as 5G NR wireless communication protocols. For illustration, the base station 105 may use one or more downlink wireless communication channels, such as via one or more of the PDSCH or PDCCH, to communicate with the UE 115. The UE 115 may use one or more uplink wireless communication channels, such as via one or more of the PUSCH or PUCCH, to communicate with the base station 105.

[0059] During operation, base station 105 may transmit signal 320 including private message (p-message) 322 and public message (c-message) 324. p-message 322 may be associated with UE 115, and c-message 324 may be associated with UE 115 and at least one other UE. For example, p-message 322 may include data that is "unique" to UE 115, and c-message 324 may include data broadcast to multiple UEs including UE 115. In some examples, base station 105 may combine p-message 322 and c-message 324 into signal 320 using message combiner 302, such as according to RS or RSMA techniques.

[0060] To illustrate, the base station 105 may use a message combiner 302 to combine common portions of various messages destined for multiple UEs (including UE 115 and at least one other UE), and may process the combined portions (which may include coding and modulation) to generate a c-message 324. The base station 105 may separately process the private portions of the various messages (which may include coding and modulation) to determine p-messages (including p-message 322). The base station 105 may pre-decode the p-message and c-message 324 to generate multiple streams (including signal 320, which may correspond to one of the streams), and may transmit one or more streams via a transmit antenna of the base station 105. In some examples, the streams may be transmitted via one base station or transmit and receive point (TRP) or via multiple base stations or TRPs, such as in conjunction with a coordinated multi-point transmission (CoMP) scheme.

[0061] UE 115 may receive signal 320, such as via a PDSCH. In some examples, UE 115 may "extract" p-message 322 and c-message 324 from signal 320 using message splitter 370, such as using RS or RSMA techniques. In some implementations, UE 115 may decode p-message 322 based on c-message 324 using successive interference cancellation (SIC). For illustration, UE 115 may perform channel estimation based on c-message 324 to determine a channel estimate (such as a channel estimate for a PDSCH used to receive signal 320). UE 115 may re-encode c-message 324, and may adjust the re-encoded c-message 324 based on the channel estimate to generate a reconstructed signal portion. UE 115 may subtract the reconstructed signal portion from signal 320 to generate an estimate of p-message 322, and may decode p-message 322 based at least in part on the estimate.

[0062] The UE 115 may determine a first CSI 342 associated with the p-message 322, and may determine a second CSI 344 associated with the c-message 324. For example, the UE 115 may determine the first CSI 342 and the second CSI 344 based on decoding of the signal 320 (or based on a parameter determined by the UE 115 during decoding of the signal 320). To further illustrate, the first CSI 342 may include one or more of a first signal to interference plus noise ratio (SINR) associated with the p-message 322, a first channel quality indicator (CQI) associated with the p-message 322, a first rank indicator (RI) associated with the p-message 322, a first modulation and coding scheme (MCS) associated with the p-message 322, or another parameter. Alternatively or in addition, the second CSI 344 may include one or more of a second SINR associated with the c-message 324, a second CQI associated with the c-message 324, a second RI associated with the c-message 324, a second MCS associated with the c-message 324, or another parameter.

[0063] In some examples, base station 105 can send reference signal 330 in conjunction with signal 320. UE 115 can receive reference signal 330 and can use reference signal 330 to decode signal 320. UE 115 can determine one or more of first CSI 342 or second CSI 344 based on reference signal 330. In some examples, reference signal 330 can correspond to a demodulation reference signal (DMRS). In some other examples, reference signal 330 can correspond to another reference signal, such as a CSI reference signal (CSI-RS).

[0064] In another example, the base station 105 may transmit different respective reference signals associated with the p-message 322 and the c-message 324. In such an example, the UE 115 may receive a first reference signal associated with the p-message 322 and may receive a second reference signal associated with the c-message 324. The UE 115 may determine a first CSI 342 based on the first reference signal and may determine a second CSI 344 based on the second reference signal.

[0065] Alternatively or in addition, the UE 115 may determine one or more of the first CSI 342 or the second CSI 344 based on one or more other techniques. For example, the UE 115 may determine a first log-likelihood ratio (LLR) value 372 associated with a first data portion of the p-message 322, and may determine a second LLR value 374 associated with a second data portion of the c-message 324. To illustrate, in some examples, the receiver 358 may determine the first LLR value 372 based on decoding of the p-message 322, and may determine the second LLR value 374 based on decoding of the c-message 324. As an illustrative example, the UE 115 may decode the p-message 322 and the c-message 324 using a low-density parity check (LDPC) decoder and determine the first LLR value 372 and the second LLR value 374.

[0066] UE 115 may send a measurement report 340 (such as a CSI measurement report) to base station 105 based on signal 320. In some examples, measurement report 340 may be associated with one or both of first CSI 342 or second CSI 344. For example, measurement report 340 may indicate one or more of first CSI 342, second CSI 344, or a metric 346 representing a combination of first CSI 342 and second CSI 344. For illustration, in some examples, measurement report 340 may indicate first CSI 342 and may not indicate (or may exclude) second CSI 344. In some other examples, measurement report 340 may indicate second CSI 344 and may not indicate (or may exclude) first CSI 342. In some other examples, measurement report 340 may indicate metric 346 and may not include (or may exclude) one or both of first CSI 342 or second CSI 344.

[0067] To further illustrate, in some implementations, the metric 346 may include or may be based on a combination or average of parameters associated with the first CSI 342 and the second CSI 344. For example, the metric 346 may include or may be based on one or more of a combined or average SINR associated with the first CSI 342 and the second CSI 344, a combined or average CQI associated with the first CSI 342 and the second CSI 344, a combined or average RI associated with the first CSI 342 and the second CSI 344, a combined or average MCS associated with the first CSI 342 and the second CSI 344, or another combined or average parameter.

[0068] In some implementations, the base station 105 may send one or more configuration messages 314 to the UE 115. For example, the base station 105 may send the one or more configuration messages 314 to the UE 115 before sending the signal 320. As illustrative examples, the one or more configuration messages 314 may include downlink control information (DCI), radio resource control (RRC) signaling, or medium access control (MAC) control element (MAC-CE) signaling. The one or more configuration messages 314 may indicate one or more reporting parameters associated with the measurement report 340. For illustration, a configuration message in the one or more configuration messages 314 may indicate whether the UE 115 is to report the first CSI 342, the second CSI 344, or the metric 346, and the measurement report 340 may indicate one or more of the first CSI 342, the second CSI 344, or the metric 346 according to the configuration message.

[0069] In some examples, one or more configuration messages 314 may include a configuration message indicating whether the second CSI 344 is to be determined before determining the first CSI 342 or whether the first CSI 342 and the second CSI 344 are to be determined concurrently (or in parallel). To illustrate, in some implementations, the UE 115 may complete decoding of the c-message 324 before completing decoding of the p-message 322, such as where the p-message 322 is encrypted or more strongly encoded than the c-message 324, which may increase the privacy associated with the p-message 322. In some such examples, the UE 115 may determine the second CSI 344 before determining the first CSI 342, and the configuration message may indicate that the UE 115 is to report the second CSI 344 before reporting the first CSI 342.

[0070] In some examples, the one or more configuration messages 314 may include a configuration message indicating one or both of the following: whether the UE 115 encodes the first CSI 342 and the second CSI 344 separately or jointly, or whether the UE transmits the first CSI 342 and the second CSI 344 via common resources or via separate resources. For example, the common resources may include one or more of common resource blocks (RBs) or common orthogonal frequency division multiplexing (OFDM) symbols, and the separate resources may include one or more of separate RBs or separate OFDM symbols. The UE 115 may transmit the first CSI 342 and the second CSI 344 according to the configuration message.

[0071] In some implementations, the UE 115 may report the first CSI 342 and the second CSI 344 in conjunction with a hybrid automatic repeat request (HARQ) process. For example, the UE 115 may send a HARQ message 334 with the measurement report 340 to the base station 105, such as by bundling the measurement report 340 with the HARQ message 334. In some examples, the HARQ message 334 may indicate an acknowledgement (ACK) of the signal 320 or a negative acknowledgement (NACK) of the signal 320. To further illustrate, in some implementations, the UE 115 may complete decoding of the c-message 324 before completing decoding of the p-message 322. In some such examples, the UE 115 may bundle the second CSI 344 with the HARQ message, both of which may be generated faster than the first CSI 342 in some cases.

[0072] In some examples, the p-message 322 and the c-message 324 may be associated with different corresponding HARQ resources and may be associated with different HARQ messages. For example, the p-message 322 may be associated with a first HARQ resource and the c-message 324 may be associated with a second HARQ resource. The first CSI 342 may be multiplexed with a first HARQ message associated with the p-message 322, and the second CSI 344 may be multiplexed with a second HARQ message associated with the c-message 324. The first HARQ message may indicate a first ACK or NACK associated with the p-message 322, and the second HARQ message may indicate a second ACK or NACK associated with the c-message 324. In another example, the UE 115 may send both the first HARQ message and the second HARQ message via the first HARQ resource or the second HARQ resource.

[0073] The first CSI 342 and the second CSI 344 may be associated with different respective target block error rate (BLER) metrics or with a common BLER metric. For illustration, a configuration message in the one or more configuration messages 314 may indicate one or more of a first target block error rate (BLER) metric 360 associated with the p-message 322 or a second target BLER metric 362 associated with the c-message 324. The UE 115 may send a measurement report 340 based on the configuration message. Alternatively or in addition, the UE 115 may send a measurement report 340 based on one or more of a first MCS table 364 associated with the p-message 322 or a second MCS table 366 associated with the c-message 324.

[0074] In some implementations, the first CSI 342 and the second CSI 344 are associated with a priority scheme 368. The priority scheme 368 may indicate respective priorities associated with reporting the first CSI 342 and the second CSI 344. In such examples, one or both of the first CSI 342 or the second CSI 344 are included in the measurement report 340 according to the priority scheme 368. For illustration, in some implementations, the measurement report 340 may have a specific number of bits available for CSI reporting. If including both the first CSI 342 and the second CSI 344 in the measurement report 340 would exceed the specific number of bits available for CSI reporting, the UE 115 may select one of the first CSI 342 or the second CSI 344 based on the priority scheme 368. In some implementations, the priority scheme 368 can indicate that the first CSI 342 has a higher priority than the second CSI 344 because, for example, the first CSI 342 can correspond to a p-message 322, which can be dedicated to the UE 115 and can contain higher priority data than the c-message 324. In some such examples, the UE 115 can "discard" the second CSI 344 from the measurement report 340. In some other examples, the priority scheme 368 can indicate that the second CSI 344 has a higher priority than the first CSI 342. In some such examples, the UE 115 can "discard" the first CSI 342 from the measurement report 340.

[0075] In some examples, the base station 105 may configure the UE 115 with a reporting configuration for the first CSI 342 and the second CSI 344, such as where the first CSI 342 and the second CSI 344 "share" a common reporting configuration. In some examples, the reporting configuration may indicate a sequence or other metric for reporting the first CSI 342 and the second CSI 344. For illustration, one or more configuration messages 314 may include a configuration indicating the reporting configuration. The measurement report 340 may indicate one of the first CSI 342 or the second CSI 344 according to the reporting configuration, and the UE 115 may send a second measurement report indicating the other of the first CSI 342 or the second CSI 344 according to the reporting configuration.

[0076] In an example, the reference signal 330 may correspond to a CSI-RS, and the base station 105 may precode the reference signal 330 via the same precoding technique as the p-message 322 and the c-message 324. The UE 115 may decode the p-message 322 and the c-message 324 (such as based on the same precoding technique) to determine the corresponding precoding channel for each of the p-message 322 and the c-message 324, and may identify the "best" precoding channel for each such message. For example, the UE 115 may identify the precoding channel with the maximum SINR or other metric, and may report the identified precoding channel to the base station 105.

[0077] In some implementations, the base station 105 can pre-decode the p-message 322 and the c-message 324 using different respective pre-decoders before transmitting the signal 320. For example, the base station 105 can pre-decode the p-message 322 using the first pre-decoder 310, and can pre-decode the c-message 324 using the second pre-decoder 312 that is different from the first pre-decoder 310. In such examples, the p-message 322 can be associated with the first pre-decoder 310, and the c-message 324 can be associated with the second pre-decoder 312.

[0078] In some examples, the UE 115 may determine different corresponding channel measurements (or channel estimates) based on the p-message 322 and the c-message 324. For example, the measurement report 340 may indicate a first channel measurement indicator associated with the p-message 322 and a second channel measurement indicator associated with the c-message 324. In some examples, the UE 115 may measure one or more parameters (such as one or more of reference signal received power (RSRP), reference signal received quality (RSRQ), or SINR) for a plurality of different resources for each of the p-message 322 and the c-message 324 to determine a plurality of channel measurement indicators for each of the p-message 322 and the c-message 324. The first channel measurement indicator may correspond to a resource having a maximum RSRP, RSRQ, or SINR among the plurality of channel measurement indicators for the p-message 322, and the second channel measurement indicator may correspond to a resource having a maximum RSRP, RSRQ, or SINR among the plurality of channel measurement indicators for the c-message 324.

[0079] In some implementations, the base station 105 may configure different parameters for the p-message 322 and the c-message 324, such as via one or more configuration messages 314. For illustration, the base station 105 may send a configuration message in the one or more configuration messages 314 to the UE 115, the configuration message indicating one or more of a precoding type, a codebook type, or a codebook restriction for each of the p-message 322 and the c-message 324. The UE 115 may send a measurement report 340 based on the configuration message. For further illustration, in some examples, the configuration message may indicate that the p-message 322 is pre-decoded via the first pre-decoder 310, and may further indicate that the c-message 324 is pre-decoded via the second pre-decoder 312.

[0080] In some implementations, the base station 105 may send the c-message 324 using a wider beam or pre-decoder than the p-message 322, which may enable the c-message 324 to reach more UEs than the p-message 322 (which may be unique to the UE 115). The base station 105 may configure the UE 115 to have such a beam or pre-decoder via a pre-coding matrix indicator (PMI) configuration message, which may be included in one or more configuration messages 314. In some cases, the base station 105 may limit or exclude some beams or pre-decoders from eligibility for the p-message 322, the c-message 324, or both. For example, the base station 105 may exclude (such as via a first codebook subset restriction) one or more wider beams or pre-decoders from eligibility for the p-message 322, and may exclude (such as via a second codebook subset restriction) one or more narrower beams or pre-decoders from eligibility for the c-message 324. Therefore, the beams or pre-decoders may be independently configured, restricted, or both configured and restricted for the p-message 322 and the c-message 324 .

[0081] In some examples, the first CSI 342 and the second CSI 344 may be associated with different subband resolutions. For illustration, the first CSI 342 may be associated with a first subband resolution, and the second CSI 344 may be associated with a second subband resolution different from the first subband resolution. In some examples, the first subband resolution may be less than the second subband resolution. For example, the first subband resolution may correspond to a first number of subbands, and the second subband resolution may correspond to a second number of subbands greater than the first number. In some examples, the second subband resolution may be broadband based.

[0082] Alternatively or in addition, in some examples, the UE 115 can use different respective numbers of bits to report the first CSI 342 and the second CSI 344. For illustration, the first CSI 342 can be associated with a first number of bits, and the second CSI 344 can be associated with a second number of bits that is different from the first number of bits. In some examples, the first number of bits can be less than the second number of bits.

[0083] The base station 105 may receive one or more of the first CSI 342, the second CSI 344, or the metric 346 from the UE 115. For example, the base station 105 may receive a measurement report 340 indicating one or more of the first CSI 342, the second CSI 344, or the metric 346. The base station 105 may perform one or more operations based on the one or more of the first CSI 342, the second CSI 344, or the metric 346. For example, the one or more operations may include determining or adjusting one or more parameters associated with the UE 115.

[0084] As an illustrative example, based on the first CSI 342 failing to meet the threshold metric, the base station 105 may adjust from using the first predecoder 310 to a third predecoder associated with a p-message to be sent to the UE 115, which may improve the reception of the p-message by the UE 115. As another illustrative example, based on the second CSI 344 failing to meet the threshold metric, the base station 105 may adjust from using the second predecoder 312 to a fourth predecoder associated with a c-message, which may improve the reception of the c-message by the UE 115. As an additional example, based on the metric 346 failing to meet the threshold metric, the base station 105 may adjust from using one or both of the first predecoders 310 to the third predecoder, or from using the second predecoder 312 to the fourth predecoder, which may improve the reception of one or both of the p-message or the c-message by the UE 115. To further illustrate, in some examples, performing one or more operations (such as by changing a predecoder) may reduce a first BLER associated with a p-message (e.g., so that the first BLER is within a first target BLER metric 360), may reduce a second BLER associated with a c-message (e.g., so that the second BLER is within a second target BLER metric 362), or both.

[0085] Alternatively or in addition to adjusting the pre-decoder, one or more operations may include adjusting one or more other metrics. For example, as an illustrative example, alternatively or in addition to adjusting the pre-decoder, the base station 105 may adjust one or more of the rank associated with the UE 115 or the MCS associated with the UE 115.

[0086] Although some examples are described with reference to base station 105 and UE 115, other examples are also within the scope of the present disclosure. For example, in some aspects, UE 115 may include a message assembler corresponding to message assembler 302 and may perform one or more operations described with reference to base station 105. For example, UE 115 may communicate with one or more base stations, one or more other UEs, or a combination thereof in accordance with RS or RSMA techniques using one or more operations described with reference to base station 105.

[0087] One or more aspects described herein can improve the performance of one or more devices of a wireless communication system, such as the wireless communication system 300. For example, by reporting CSI associated with a p-message 322 and a c-message 324, such as one or more of a first CSI 342, a second CSI 344, or a metric 346, the base station 105 can independently determine or adjust one or more parameters associated with the p-message, the c-message, or both. For illustration, the one or more parameters may include a precoder, a rank, or an MCS. By independently adjusting the one or more parameters, the base station 105 can independently reduce the BLER metrics associated with the p-message and the c-message to within a first target BLER metric 360 and a second target BLER metric 362, respectively. Thus, the reception of p-messages and c-messages within the wireless communication system 300 can be improved, which in some cases can reduce the number of NACK messages and retransmissions.

[0088] Figure 4 is a flow diagram illustrating an example process 400 for supporting CSI reporting for one or both of a p-message or a c-message in accordance with one or more aspects. The operations of process 400 may be performed by a UE, such as UE 115.

[0089] In block 402, UE 115 receives a signal including a p-message associated with the UE and a c-message associated with the UE and at least one other UE. For example, UE 115 may receive signal 320 including p-message 322 and c-message 324. p-message 322 may be associated with UE 115, and c-message 324 may be associated with UE 115 and at least one other UE.

[0090] In block 404, the UE 115 sends a measurement report indicating one or both of the first CSI associated with the p-message or the second CSI associated with the c-message. For example, the UE 115 may send a measurement report 340 indicating one or more of the first CSI 342, the second CSI 344, or the metric 346.

[0091] Figure 5is a flow diagram illustrating an example process 500 for supporting CSI reporting for one or both of a p-message or a c-message in accordance with one or more aspects. The operations of process 500 may be performed by a base station, such as base station 105.

[0092] In block 502, base station 105 transmits a signal including a p-message associated with a UE and a c-message associated with the UE and at least one other UE. For example, base station 105 may transmit signal 320 including p-message 322 and c-message 324. p-message 322 may be associated with UE 115, and c-message 324 may be associated with UE 115 and at least one other UE.

[0093] In block 504, the base station 105 receives a measurement report from the UE indicating one or both of the first CSI associated with the p-message or the second CSI associated with the c-message. For example, the base station 105 may receive a measurement report 340 indicating one or more of the first CSI 342, the second CSI 344, or the metric 346.

[0094] Figure 6 1 is a block diagram illustrating an example of a UE 115 according to some aspects of the present disclosure. The UE 115 may include Figure 2 2. For example, the UE 115 may include a processor 280 that may execute instructions stored in a memory 282. Using the processor 280, the UE 115 may send and receive signals via the radios 601a-r and antennas 252a-r. The radios 601a-r may include one or more components or devices described herein, such as a modulator / demodulator 254a-r, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a transmitter 356, a receiver 358, one or more other components or devices, or a combination thereof.

[0095] In some examples, the memory 282 may store instructions executable by one or more processors, such as the processor 280, to initiate, perform, or control one or more operations described herein. For example, the memory 282 may store message segmentation instructions 602 executable by the processor 280 to determine the p-message 322 and the c-message 324 based on the signal 320 (such as using RS or RSMA techniques). As another example, the memory 282 may store p-message CSI determination instructions 604 and c-message CSI determination instructions 606 executable by the processor 280 to determine the first CSI 342 and the second CSI 344, respectively. As an additional example, the memory 282 may store measurement reporting instructions 608 executable by the processor 280 to send the measurement report 340.

[0096] Figure 7 is a block diagram illustrating an example of a base station 105 according to some aspects of the present disclosure. The base station 105 may include Figure 2 2. For example, the base station 105 may include a processor 240 that may execute instructions stored in a memory 242. Under the control of the processor 240, the base station 105 may send and receive signals via the radios 701a-t and the antennas 234a-t. The radios 701a-t may include one or more components or devices described herein, such as the modulator / demodulator 232a-t, the MIMO detector 236, the receive processor 238, the transmit processor 220, the TX MIMO processor 230, the transmitter 306, the receiver 308, one or more other components or devices, or a combination thereof.

[0097] In some examples, memory 242 may store instructions executable by one or more processors (such as processor 240) to initiate, perform, or control one or more operations described herein. For example, memory 242 may store message combination instructions 702 executable by processor 240 to generate a signal based on p-message 322 and c-message 324 (such as using RS or RSMA techniques). As another example, memory 242 may store CSI-based parameter adjustment instructions 704 executable to receive measurement report 340 and adjust one or more parameters associated with UE 115 based on measurement report 340. For example, as an illustrative example, base station 105 may perform reference, such as by adjusting one or more of a pre-decoder associated with UE 115, a rank associated with UE 115, or an MCS associated with UE 115. Figure 3 One or more operations described.

[0098] Figure 8A diagram illustrating an example disaggregated base station 800 architecture according to some aspects of the present disclosure is shown. In some examples, the disaggregated base station 800 architecture may be used to implement a base station 105. The disaggregated base station 800 architecture may include one or more central units (CUs) 810 that may communicate directly with a core network 820 via a backhaul link, or indirectly with the core network 820 through one or more disaggregated base station units, such as a near real-time (near-RT) RAN intelligent controller (RIC) 825 via an E2 link, or a non-real-time (non-RT) RIC 815 associated with a service management and orchestration (SMO) framework 805, or both. The CU 810 may communicate with one or more distributed units (DUs) 830 via respective midhaul links, such as an F1 interface. The DU 830 may communicate with one or more radio units (RUs) 840 via respective fronthaul links. The RU 840 may communicate with respective UEs 115 via one or more radio frequency (RF) access links. In some implementations, a UE 115 can be served by multiple RUs 840 simultaneously.

[0099] Each of the units (i.e., CU 810, DU 830, RU 840, and near-RT RIC 825, non-RT RIC 815, and SMO framework 805) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interface of these units may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface configured to receive or send signals to one or more of the other units via a wired transmission medium. Additionally, the unit may include a wireless interface that may include a receiver, a transmitter, or a transceiver (such as a radio frequency (RF) transceiver) that is configured to receive or send signals, or both, to one or more of the other units via a wireless transmission medium.

[0100] In some aspects, the CU 810 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 810. The CU 810 may be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, the CU 810 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 810 may be implemented to communicate with the DU 830 for network control and signaling.

[0101] DU 830 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 840. In some aspects, DU 830 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) depending at least in part on a functional split such as that defined by the Third Generation Partnership Project (3GPP). In some aspects, DU 830 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 830 or with control functions hosted by CU 810.

[0102] The lower layer functionality may be implemented by one or more RUs 840. In some deployments, a RU 840 controlled by a DU 830 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on a functional split (such as a lower layer functional split). In such an architecture, the RU 840 may be implemented to handle over-the-air (OTA) communications with one or more UEs 115. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 840 may be controlled by the corresponding DU 830. In some scenarios, this configuration may enable the implementation of the DU 830 and the CU 810 in a cloud-based RAN architecture (such as a vRAN architecture).

[0103] The SMO framework 805 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 805 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 805 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 890) to perform network element lifecycle management (such as to instantiate 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 810, DU 830, RU 840, and near-RT RIC 825. In some specific implementations, the SMO framework 805 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 811) via the O1 interface. Additionally, in some specific implementations, the SMO framework 805 may communicate directly with one or more RU840 via the O1 interface. The SMO framework 805 may also include a non-RT RIC 815 configured to support the functionality of the SMO framework 805 .

[0104] The non-RT RIC 815 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 825. The non-RT RIC 815 may be coupled to or communicate with the near-RT RIC 825 (such as via an A1 interface). The near-RT RIC 825 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 810, one or more DUs 830, or both, and the O-eNB with the near-RT RIC 825.

[0105] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 825, the non-RT RIC 815 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 825 and may be received from a non-network data source or from a network function at the SMO framework 805 or the non-RT RIC 815. In some examples, the non-RT RIC 815 or the near-RT RIC 825 may be configured to regulate RAN behavior or performance. For example, the non-RT RIC 815 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 805 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0144] Additionally, one of ordinary skill in the art will readily recognize that the terms "upper" and "lower" are sometimes used for ease of describing the drawings and indicate relative positions on a properly oriented page corresponding to the orientation of the drawing, and may not reflect the proper orientation of any device as implemented.

[0145] Certain features described in this specification in the context of a single implementation may also be implemented in combination in a single implementation. Conversely, various features described in the context of a single implementation may also be implemented in multiple implementations individually or in any suitable subcombination. Furthermore, while some features are described above as working in a particular combination and even initially claimed as such, in some cases one or more features from a claimed combination may be cut out of the combination, and a claimed combination may involve a subcombination or a variation of a subcombination.

[0146] Similarly, although the operations are depicted in a specific order in the figure, this should not be understood as requiring such operations to be performed in the specific order shown or in a sequential order, or to perform all the illustrated operations to achieve the desired result. In addition, the accompanying drawings can schematically depict one or more example processes in the form of a flow chart. However, other operations not depicted can be incorporated into the example process schematically illustrated. For example, one or more additional operations can be performed before, after, at the same time, or between any operations in the illustrated operation. In some environments, multitasking and parallel processing are advantageous. In addition, the separation of various system components in the specific implementation described above should not be understood as requiring such separation in all specific implementations, but it should be understood that the described program components and systems can usually be integrated together in a single software product, or be packaged in multiple software products. Additionally, some other specific implementations also fall within the scope of the appended claims. In some cases, the actions recorded in the claims can be performed in different orders and still achieve the desired result.

[0147] As used herein, including in the claims, the term "or," when used in a list of two or more items, means that any one of the listed items may be used alone, or any combination of two or more of the listed items may be used. For example, if a composition is described as comprising components A, B, or C, the composition may comprise A alone; B alone; C alone; A and B combined; A and C combined; B and C combined; or A, B, and C combined. In addition, as used herein (including in the claims), "or" as used in a list of items beginning with "at least one" indicates a separate list, so that, for example, a list of "at least one of A, B, or C" means A or B or C or AB or AC or BC or ABC (i.e., A and B and C) or any combination of any of these. The term "substantially" is defined as largely, but not necessarily entirely, what is specified (and includes what is specified; for example, substantially 90 degrees includes 90 degrees, and substantially parallel includes parallel), as understood by one of ordinary skill in the art. In any disclosed implementation, the term "substantially" may be replaced with "within [percent] of" a specified content, where the percentage includes 0.1%, 1%, 5%, or 10%.

[0148] The previous description of the disclosure is provided to enable any person skilled in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the spirit or scope of the disclosure. Therefore, the disclosure is not intended to be limited to the examples and designs described herein, but to be consistent with the widest scope consistent with the principles and novel features disclosed herein.
