[0003] Wireless communications systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasts, or other similar types of services. These wireless communications systems may employ multiple-access technologies capable of supporting communications with multiple users by sharing available wireless communications system resources with those users.

[0004] Although wireless communications systems have made great technological advancements over many years, challenges still exist. For example, complex and dynamic environments can still attenuate or block signals between wireless transmitters and wireless receivers. Accordingly, there is a continuous desire to improve the technical performance of wireless communications systems, including, for example: improving speed and data carrying capacity of communications, improving efficiency of the use of shared communications mediums, reducing power used by transmitters and receivers while performing communications, improving reliability of wireless communications, avoiding redundant transmissions and / or receptions and related processing, improving the coverage area of wireless communications, increasing the number and types of devices that can access wireless communications systems, increasing the ability for different types of devices to intercommunicate, increasing the number and type of wireless communications mediums available for use, and the like.

[0023] Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer-readable mediums for managing distortion in edges of a bandwidth used for transmitting uplink transmissions.P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 4

[0024] Wireless communication devices, such as user equipment (UEs), rely on filters as a critical component of their transmission and reception systems. These filters are designed to ensure that signals stay within an allocated bandwidth (BW) while blocking out unwanted frequencies. However, a drawback of these filters is that these filters may introduce distortion at the edges of the allocated BW.

[0025] This distortion at the BW edges may arise from various factors, such as hardware imperfections, non-linearities, or phase noise effects. The issue of distortion on the BW edges is particularly relevant in the uplink (UL). According to current standards, each UE may be configured to indicate the maximum MCS order it can support for the entire BW based on an error vector magnitude (EVM) of its transmitted signal. The EVM represents the maximum error the UE can guarantee for its UL transmissions. The EVM is often higher at the BW edges due to distortion and lower at the center portion of the allocated BW, where signal quality tends to be better. Even though the EVM at the center of the allocated BW may support a higher MCS, the higher EVM at the BW edges will ultimately dictate the MCS that the UE can use across the entire BW, resulting in reduced code rates and overall throughput.

[0026] Accordingly, aspects of the present disclosure provide techniques for improving code rates and overall throughput in an allocated UL BW, especially in scenarios where EVM may vary across different portions of the allocated UL BW. For example, in some cases, instead of reporting a maximum MCS or MCS order that the UE can support across the entire allocated UL BW, the techniques presented herein may involve the UE reporting a plurality of different EVM guarantees for different portions of the allocated UL BW.

[0027] In some cases, by indicating different EVMs that the UE is able to guarantee for the different portions of the allocated UL BW, a network entity may configure the UE with different MCSs for the different portions of the allocated UL BW. The UE may then use the plurality of MCSs when transmitting the UL transmissions. For example, in some cases, a first MCS for a center portion of the allocated UL BW may be higher than the second MCS for edge portions of the allocated UL BW, allowing the UE to transmit the UL transmissions in the center portion with a higher code rate and higher throughput relative to UL transmissions transmitted in the edge portions.P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 5Introduction to Wireless Communications Networks

[0028] The techniques and methods described herein may be used for various wireless communications networks. While aspects may be described herein using terminology commonly associated with 3G, 4G, and / or 5G wireless technologies, aspects of the present disclosure may likewise be applicable to other communications systems and standards not explicitly mentioned herein.

[0029] FIG. 1 depicts an example of a wireless communications network 100, in which aspects described herein may be implemented.

[0030] Generally, wireless communications network 100 includes various network entities (alternatively, network elements or network nodes). A network entity is generally a communications device and / or a communications function performed by a communications device (e.g., a user equipment (UE), a base station (BS), a component of a BS, a server, etc.). For example, various functions of a network as well as various devices associated with and interacting with a network may be considered network entities. Further, wireless communications network 100 includes terrestrial aspects, such as ground-based network entities (e.g., BSs 102), and non-terrestrial aspects, such as satellite 140 and aircraft 145, which may include network entities on-board (e.g., one or more BSs) capable of communicating with other network elements (e.g., terrestrial BSs) and user equipments.

[0031] In the depicted example, wireless communications network 100 includes BSs 102, UEs 104, and one or more core networks, such as an Evolved Packet Core (EPC) 160 and 5G Core (5GC) network 190, which interoperate to provide communications services over various communications links, including wired and wireless links.

[0032] FIG. 1 depicts various example UEs 104, which may more generally include: a cellular phone, smart phone, session initiation protocol (SIP) phone, laptop, personal digital assistant (PDA), satellite radio, global positioning system, multimedia device, video device, digital audio player, camera, game console, tablet, smart device, wearable device, vehicle, electric meter, gas pump, large or small kitchen appliance, healthcare device, implant, sensor / actuator, display, internet of things (loT) devices, always on (AON) devices, edge processing devices, or other similar devices. UEs 104 may also be referred to more generally as a mobile device, a wireless device, a wireless communications device, a station, a mobile station, a subscriber station, a mobileP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 6subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a remote device, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, and others.

[0033] BSs 102 wirelessly communicate with (e.g., transmit signals to or receive signals from) UEs 104 via communications links 120. The communications links 120 between BSs 102 and UEs 104 may include uplink (UL) (also referred to as reverse link) transmissions from a UE 104 to a BS 102 and / or downlink (DL) (also referred to as forward link) transmissions from a BS 102 to a UE 104. The communications links 120 may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity in various aspects.

[0034] BSs 102 may generally include: a NodeB, enhanced NodeB (eNB), next generation enhanced NodeB (ng-eNB), next generation NodeB (gNB or gNodeB), access point, base transceiver station, radio base station, radio transceiver, transceiver function, transmission reception point, and / or others. Each of BSs 102 may provide communications coverage for a respective geographic coverage area 110, which may sometimes be referred to as a cell, and which may overlap in some cases (e.g., small cell 102’ may have a coverage area 110’ that overlaps the coverage area 110 of a macro cell). A BS may, for example, provide communications coverage for a macro cell (covering relatively large geographic area), a pico cell (covering relatively smaller geographic area, such as a sports stadium), a femto cell (relatively smaller geographic area (e.g., a home)), and / or other types of cells.

[0035] While BSs 102 are depicted in various aspects as unitary communications devices, BSs 102 may be implemented in various configurations. For example, one or more components of a base station may be disaggregated, including a central unit (CU), one or more distributed units (DUs), one or more radio units (RUs), a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC), or a Non-Real Time (Non-RT) RIC, to name a few examples. In another example, various aspects of a base station may be virtualized. More generally, a base station (e.g., BS 102) may include components that are located at a single physical location or components located at various physical locations. In examples in which a base station includes components that are located at various physical locations, the various components may each perform functions such that, collectively, the various components achieve functionality that is similar to a base station that is located at a single physical location. In some aspects, a base station includingP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 7components that are located at various physical locations may be referred to as a disaggregated radio access network architecture, such as an Open RAN (O-RAN) or Virtualized RAN (VRAN) architecture. FIG. 2 depicts and describes an example disaggregated base station architecture.

[0036] Different BSs 102 within wireless communications network 100 may also be configured to support different radio access technologies, such as 3G, 4G, and / or 5G. For example, BSs 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC 160 through first backhaul links 132 (e.g., an SI interface). BSs 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) may interface with 5GC 190 through second backhaul links 184. BSs 102 may communicate directly or indirectly (e.g., through the EPC 160 or 5GC 190) with each other over third backhaul links 134 (e.g., X2 interface), which may be wired or wireless.

[0037] Wireless communications network 100 may subdivide the electromagnetic spectrum into various classes, bands, channels, or other features. In some aspects, the subdivision is provided based on wavelength and frequency, where frequency may also be referred to as a carrier, a subcarrier, a frequency channel, a tone, or a subband. For example, 3GPP currently defines Frequency Range 1 (FR1) as including 410 MHz - 7125 MHz, which is often referred to (interchangeably) as “Sub-6 GHz”. Similarly, 3GPP currently defines Frequency Range 2 (FR2) as including 24,250 MHz - 71,000 MHz, which is sometimes referred to (interchangeably) as a “millimeter wave” (“mmW” or “mmWave”). In some cases, FR2 may be further defined in terms of sub-ranges, such as a first sub-range FR2-1 including 24,250 MHz - 52,600 MHz and a second sub-range FR2-2 including 52,600 MHz - 71,000 MHz. A base station configured to communicate using mmWave / near mmWave radio frequency bands (e.g., a mmWave base station such as BS 180) may utilize beamforming (e.g., 182) with a UE (e.g., 104) to improve path loss and range.

[0038] The communications links 120 between BSs 102 and, for example, UEs 104, may be through one or more carriers, which may have different bandwidths (e.g., 5, 10, 15, 20, 100, 400, and / or other MHz), and which may be aggregated in various aspects. Carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL).P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 8

[0039] Communications using higher frequency bands may have higher path loss and a shorter range compared to lower frequency communications. Accordingly, certain base stations (e.g., 180 in FIG. 1) may utilize beamforming 182 with a UE 104 to improve path loss and range. For example, BS 180 and the UE 104 may each include a plurality of antennas, such as antenna elements, antenna panels, and / or antenna arrays to facilitate the beamforming. In some cases, BS 180 may transmit a beamformed signal to UE 104 in one or more transmit directions 182’. UE 104 may receive the beamformed signal from the BS 180 in one or more receive directions 182”. UE 104 may also transmit a beamformed signal to the BS 180 in one or more transmit directions 182”. BS 180 may also receive the beamformed signal from UE 104 in one or more receive directions 182’. BS 180 and UE 104 may then perform beam training to determine the best receive and transmit directions for each of BS 180 and UE 104. Notably, the transmit and receive directions for BS 180 may or may not be the same. Similarly, the transmit and receive directions for UE 104 may or may not be the same.

[0040] Wireless communications network 100 further includes a Wi-Fi AP 150 in communication with Wi-Fi stations (STAs) 152 via communications links 154 in, for example, a 2.4 GHz and / or 5 GHz unlicensed frequency spectrum.

[0041] Certain UEs 104 may communicate with each other using device-to-device (D2D) communications link 158. D2D communications link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), a physical sidelink control channel (PSCCH), and / or a physical sidelink feedback channel (PSFCH).

[0042] EPC 160 may include various functional components, including: a Mobility Management Entity (MME) 162, other MMEs 164, a Serving Gateway 166, a Multimedia Broadcast Multicast Service (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC) 170, and / or a Packet Data Network (PDN) Gateway 172, such as in the depicted example. MME 162 may be in communication with a Home Subscriber Server (HSS) 174. MME 162 is the control node that processes the signaling between the UEs 104 and the EPC 160. Generally, MME 162 provides bearer and connection management.

[0043] Generally, user Internet protocol (IP) packets are transferred through Serving Gateway 166, which itself is connected to PDN Gateway 172. PDN Gateway 172P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 9provides UE IP address allocation as well as other functions. PDN Gateway 172 and the BM-SC 170 are connected to IP Services 176, which may include, for example, the Internet, an intranet, an IP Multimedia Subsystem (IMS), a Packet Switched (PS) streaming service, and / or other IP services.

[0044] BM-SC 170 may provide functions for MBMS user service provisioning and delivery. BM-SC 170 may serve as an entry point for content provider MBMS transmission, may be used to authorize and initiate MBMS Bearer Services within a public land mobile network (PLMN), and / or may be used to schedule MBMS transmissions. MBMS Gateway 168 may be used to distribute MBMS traffic to the BSs 102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service, and / or may be responsible for session management (start / stop) and for collecting eMBMS related charging information.

[0045] 5GC 190 may include various functional components, including: an Access and Mobility Management Function (AMF) 192, other AMFs 193, a Session Management Function (SMF) 194, and a User Plane Function (UPF) 195. AMF 192 may be in communication with Unified Data Management (UDM) 196.

[0046] AMF 192 is a control node that processes signaling between UEs 104 and 5GC 190. AMF 192 provides, for example, quality of service (QoS) flow and session management.

[0047] Internet protocol (IP) packets are transferred through UPF 195, which is connected to the IP Services 197, and which provides UE IP address allocation as well as other functions for 5GC 190. IP Services 197 may include, for example, the Internet, an intranet, an IMS, a PS streaming service, and / or other IP services.

[0048] In various aspects, a network entity or network node can be implemented as an aggregated base station, as a disaggregated base station, a component of a base station, an integrated access and backhaul (IAB) node, a relay node, a sidelink node, to name a few examples.

[0049] FIG. 2 depicts an example disaggregated base station 200 architecture. The disaggregated base station 200 architecture may include one or more central units (CUs) 210 that can communicate directly with a core network 220 via a backhaul link, or indirectly with the core network 220 through one or more disaggregated base station units (such as a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC) 225 via an E2P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 10link, or aNon-Real Time (Non-RT) RIC 215 associated with a Service Management and Orchestration (SMO) Framework 205, or both). A CU 210 may communicate with one or more distributed units (DUs) 230 via respective midhaul links, such as an Fl interface. The DUs 230 may communicate with one or more radio units (RUs) 240 via respective fronthaul links. The RUs 240 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, the UE 104 may be simultaneously served by multiple RUs 240.

[0050] Each of the units, e.g., the CUs 210, the DUs 230, the RUs 240, as well as the Near-RT RICs 225, the Non-RT RICs 215 and the SMO Framework 205, may include one or more interfaces or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to the communications interfaces of the units, can be configured to communicate with one or more of the other units via the transmission medium. For example, the units can include a wired interface configured to receive or transmit signals over a wired transmission medium to one or more of the other units. Additionally or alternatively, the units can include a wireless interface, which may include a receiver, a transmitter or transceiver (such as a radio frequency (RF) transceiver), configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other units.

[0051] In some aspects, the CU 210 may host one or more higher layer control functions. Such control functions can include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), or the like. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 210. The CU 210 may be configured to handle user plane functionality (e.g., Central Unit - User Plane (CU-UP)), control plane functionality (e.g., Central Unit - Control Plane (CU-CP)), or a combination thereof. In some implementations, the CU 210 can be logically split into one or more CU-UP units and one or more CU-CP units. The CU-UP unit can communicate bidirectionally with the CU-CP unit via an interface, such as the El interface when implemented in an O-RAN configuration. The CU 210 can be implemented to communicate with the DU 230, as necessary, for network control and signaling.P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 11

[0052] The DU 230 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 240. In some aspects, the DU 230 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, or the like) depending, at least in part, on a functional split, such as those defined by the 3rdGeneration Partnership Project (3GPP). In some aspects, the DU 230 may further host one or more low PHY layers. Each layer (or module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 230, or with the control functions hosted by the CU 210.

[0053] Lower-layer functionality can be implemented by one or more RUs 240. In some deployments, an RU 240, controlled by a DU 230, 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, or the like), or both, based at least in part on the functional split, such as a lower layer functional split. In such an architecture, the RU(s) 240 can be implemented to handle over the air (OTA) communications with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control and user plane communications with the RU(s) 240 can be controlled by the corresponding DU 230. In some scenarios, this configuration can enable the DU(s) 230 and the CU 210 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0054] The SMO Framework 205 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 205 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements which may be managed via an operations and maintenance interface (such as an 01 interface). For virtualized network elements, the SMO Framework 205 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 290) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an 02 interface). Such virtualized network elements can include, but are not limited to, CUs 210, DUs 230, RUs 240 and Near-RT RICs 225. In some implementations, the SMO Framework 205 canP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 12communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 211, via an 01 interface. Additionally, in some implementations, the SMO Framework 205 can communicate directly with one or more RUs 240 via an 01 interface. The SMO Framework 205 also may include a Non-RT RIC 215 configured to support functionality of the SMO Framework 205.

[0055] The Non-RT RIC 215 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, Artificial Intelligence / Machine Learning (AI / ML) workflows including model training and updates, or policy -based guidance of applications / features in the Near-RT RIC 225. The Non-RT RIC 215 may be coupled to or communicate with (such as via an Al interface) the Near-RT RIC 225. The Near-RT RIC 225 may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (such as via an E2 interface) connecting one or more CUs 210, one or more DUs 230, or both, as well as an O-eNB, with the Near-RT RIC 225.

[0056] In some implementations, to generate AI / ML models to be deployed in the Near-RT RIC 225, the Non-RT RIC 215 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 225 and may be received at the SMO Framework 205 or the Non-RT RIC 215 from nonnetwork data sources or from network functions. In some examples, the Non-RT RIC 215 or the Near-RT RIC 225 may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 215 may monitor long-term trends and patterns for performance and employ AI / ML models to perform corrective actions through the SMO Framework 205 (such as reconfiguration via 01) or via creation of RAN management policies (such as Al policies).

[0057] FIG. 3 depicts aspects of an example BS 102 and a UE 104.

[0058] Generally, BS 102 includes various processors (e.g., 320, 330, 338, and 340), antennas 334a-t (collectively 334), transceivers 332a-t (collectively 332), which include modulators and demodulators, and other aspects, which enable wireless transmission of data (e.g., data source 312) and wireless reception of data (e.g., data sink 339). For example, BS 102 may send and receive data between BS 102 and UE 104. BS 102P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 13includes controller / processor 340, which may be configured to implement various functions described herein related to wireless communications.

[0059] Generally, UE 104 includes various processors (e.g., 358, 364, 366, and 380), antennas 352a-r (collectively 352), transceivers 354a-r (collectively 354), which include modulators and demodulators, and other aspects, which enable wireless transmission of data (e.g., retrieved from data source 362) and wireless reception of data (e.g., provided to data sink 360). UE 104 includes controller / processor 380, which may be configured to implement various functions described herein related to wireless communications.

[0060] In regards to an example downlink transmission, BS 102 includes a transmit processor 320 that may receive data from a data source 312 and control information from a controller / processor 340. The control information may be for the physical broadcast channel (PBCH), physical control format indicator channel (PCFICH), physical HARQ indicator channel (PHICH), physical downlink control channel (PDCCH), group common PDCCH (GC PDCCH), and / or others. The data may be for the physical downlink shared channel (PDSCH), in some examples.

[0061] Transmit processor 320 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. Transmit processor 320 may also generate reference symbols, such as for the primary synchronization signal (PSS), secondary synchronization signal (SSS), PBCH demodulation reference signal (DMRS), and channel state information reference signal (CSI-RS).

[0062] Transmit (TX) multiple-input multiple-output (MIMO) processor 330 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, and / or the reference symbols, if applicable, and may provide output symbol streams to the modulators (MODs) in transceivers 332a-332t. Each modulator in transceivers 332a-332t may process a respective output symbol stream to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. Downlink signals from the modulators in transceivers 332a-332t may be transmitted via the antennas 334a-334t, respectively.

[0063] In order to receive the downlink transmission, UE 104 includes antennas 352a- 352r that may receive the downlink signals from the BS 102 and may provide receivedP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 14signals to the demodulators (DEMODs) in transceivers 354a-354r, respectively. Each demodulator in transceivers 354a-354r may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator may further process the input samples to obtain received symbols.

[0064] MEMO detector 356 may obtain received symbols from all the demodulators in transceivers 354a-354r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. Receive processor 358 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE 104 to a data sink 360, and provide decoded control information to a controller / processor 380.

[0065] In regards to an example uplink transmission, UE 104 further includes a transmit processor 364 that may receive and process data (e.g., for the PUSCH) from a data source 362 and control information (e.g., for the physical uplink control channel (PUCCH)) from the controller / processor 380. Transmit processor 364 may also generate reference symbols for a reference signal (e.g., for the sounding reference signal (SRS)). The symbols from the transmit processor 364 may be precoded by a TX MIMO processor 366 if applicable, further processed by the modulators in transceivers 354a-354r (e.g., for SC-FDM), and transmitted to BS 102.

[0066] At BS 102, the uplink signals from UE 104 may be received by antennas 334a-t, processed by the demodulators in transceivers 332a-332t, detected by a MIMO detector 336 if applicable, and further processed by a receive processor 338 to obtain decoded data and control information sent by UE 104. Receive processor 338 may provide the decoded data to a data sink 339 and the decoded control information to the controller / processor 340.

[0067] Memories 342 and 382 may store data and program codes for BS 102 and UE 104, respectively.

[0068] Scheduler 344 may schedule UEs for data transmission on the downlink and / or uplink.

[0069] In various aspects, BS 102 may be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” may refer to various mechanisms of outputting data, such as outputting data from data source 312, scheduler 344, memory 342, transmit processor 320,P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 15controller / processor 340, TX MIMO processor 330, transceivers 332a-t, antenna 334a-t, and / or other aspects described herein. Similarly, “receiving” may refer to various mechanisms of obtaining data, such as obtaining data from antennas 334a-t, transceivers 332a-t, RX MIMO detector 336, controller / processor 340, receive processor 338, scheduler 344, memory 342, and / or other aspects described herein.

[0070] In various aspects, UE 104 may likewise be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” may refer to various mechanisms of outputting data, such as outputting data from data source 362, memory 382, transmit processor 364, controller / processor 380, TX MIMO processor 366, transceivers 354a-t, antenna 352a-t, and / or other aspects described herein. Similarly, “receiving” may refer to various mechanisms of obtaining data, such as obtaining data from antennas 352a-t, transceivers 354a-t, RX MIMO detector 356, controller / processor 380, receive processor 358, memory 382, and / or other aspects described herein.

[0071] In some aspects, one or more processors may be configured to perform various operations, such as those associated with the methods described herein, and transmit (output) to or receive (obtain) data from another interface that is configured to transmit or receive, respectively, the data.

[0072] FIGS. 4A, 4B, 4C, and 4D depict aspects of data structures for a wireless communications network, such as wireless communications network 100 of FIG. 1.

[0073] In particular, FIG. 4A is a diagram 400 illustrating an example of a first subframe within a 5G (e.g., 5GNR) frame structure, FIG.4B is a diagram 430 illustrating an example of DL channels within a 5G subframe, FIG. 4C is a diagram 450 illustrating an example of a second subframe within a 5G frame structure, and FIG. 4D is a diagram 480 illustrating an example of UL channels within a 5G subframe.

[0074] Wireless communications systems may utilize orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) on the uplink and downlink. Such systems may also support half-duplex operation using time division duplexing (TDD). OFDM and single-carrier frequency division multiplexing (SC-FDM) partition the system bandwidth (e.g., as depicted in FIGS. 4B and 4D) into multiple orthogonal subcarriers. Each subcarrier may be modulated with data. Modulation symbols may be sent in the frequency domain with OFDM and / or in the time domain with SC-FDM.P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 16

[0075] A wireless communications frame structure may be frequency division duplex (FDD), in which, for a particular set of subcarriers, subframes within the set of subcarriers are dedicated for either DL or UL. Wireless communications frame structures may also be time division duplex (TDD), in which, for a particular set of subcarriers, subframes within the set of subcarriers are dedicated for both DL and UL.

[0076] In FIG. 4A and 4C, the wireless communications frame structure is TDD where D is DL, U is UL, and X is flexible for use between DL / UL. UEs may be configured with a slot format through a received slot format indicator (SFI) (dynamically through DL control information (DCI), or semi-statically / statically through radio resource control (RRC) signaling). In the depicted examples, a 10 ms frame is divided into 10 equally sized 1 ms subframes. Each subframe may include one or more time slots. In some examples, each slot may include 7 or 14 symbols, depending on the slot format. Subframes may also include mini-slots, which generally have fewer symbols than an entire slot. Other wireless communications technologies may have a different frame structure and / or different channels.

[0077] In certain aspects, the number of slots within a subframe is based on a slot configuration and a numerology. For example, for slot configuration 0, different numerol ogies (p) 0 to 6 allow for 1, 2, 4, 8, 16, 32, and 64 slots, respectively, per subframe. For slot configuration 1, different numerol ogies 0 to 2 allow for 2, 4, and 8 slots, respectively, per subframe. Accordingly, for slot configuration 0 and numerology p, there are 14 symbols / slot and 2p slots / subframe. The subcarrier spacing and symbol length / duration are a function of the numerology. The subcarrier spacing may be equal to 2^ X 15 kHz, where p is the numerology 0 to 6. As such, the numerology p = 0 has a subcarrier spacing of 15 kHz and the numerology p = 6 has a subcarrier spacing of 960 kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIGS.4A, 4B, 4C, and 4D provide an example of slot configuration 0 with 14 symbols per slot and numerology p = 2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 ps.

[0078] As depicted in FIGS. 4A, 4B, 4C, and 4D, a resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs)) that extends, for example, 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 17

[0079] As illustrated in FIG.4A, some of the REs carry reference (pilot) signals (RS) for a UE (e.g., UE 104 of FIGS. 1 and 3). The RS may include demodulation RS (DMRS) and / or channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may also include beam measurement RS (BRS), beam refinement RS (BRRS), and / or phase tracking RS (PT-RS).

[0080] FIG. 4B illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs), each CCE including, for example, nine RE groups (REGs), each REG including, for example, four consecutive REs in an OFDM symbol.

[0081] A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE (e.g., 104 of FIGS. 1 and 3) to determine subframe / symbol timing and a physical layer identity.

[0082] A secondary synchronization signal (SSS) may be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing.

[0083] Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of the aforementioned DMRS. The physical broadcast channel (PBCH), which carries a master information block (MIB), may be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block. The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs), and / or paging messages.

[0084] As illustrated in FIG. 4C, some of the REs carry DMRS (indicated as R for one particular configuration, but other DMRS configurations are possible) for channel estimation at the base station. The UE may transmit DMRS for the PUCCH and DMRS for the PUSCH. The PUSCH DMRS may be transmitted, for example, in the first one or two symbols of the PUSCH. The PUCCH DMRS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. UE 104 may transmit sounding reference signals (SRS). The SRS may be transmitted, for example, in the last symbol ofP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 18a subframe. The SRS may have a comb structure, and a UE may transmit SRS on one of the combs. The SRS may be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0085] FIG. 4D illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and HARQ ACK / NACK feedback. The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.Example Transceiver Front End

[0086] FIG. 5 illustrates example components of a transceiver front end 506 of a first wireless communications device 502, which may be used to communicate with a second wireless communications devices 504.

[0087] The first wireless communications device 502 may be an example of a user equipment (UE), such as UE 104 described with respect to FIG. 1 and FIG. 3. In some cases, the second wireless communications device 504 may be an example of a network entity, such as BS 102 described with respect to FIG. 1 and FIG. 3 or a disaggregated base station described with respect to FIG. 2.

[0088] In some cases, the transceiver front end 506 may be, or may include, a chip, system on chip (SoC), chipset, package or device that includes one or more modems 512. In some cases, the one or more modems 512 may include, for example, any of a WWAN modem (e.g., a modem configured to communicate via E-UTRA and / or 5G NR standards), a WLAN modem (e.g., a modem configured to communicate via 802.11 standards), a Bluetooth modem, a NTN modem, etc. In certain aspects, the first wireless communications device 502 also includes one or more radios (collectively “the radio 550”). In some aspects, the first wireless communications device 502 further includes one or more processors, processing blocks or processing elements (collectively “the processor 510”) and one or more memory blocks or elements (collectively “the memory 540”).

[0089] In certain aspects, the processor 510 may include a processor representative of an application processor that generates information (e.g., application data such as content requests) for transmission and / or receives information (e.g., requested content) via the one or more modems 512. In some cases, the processor 510 may include aP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 19microprocessor associated with the one or more modems 512, which process any of certain protocol stack layers associated with a radio access technology (RAT). For example, the processor 510 may process any of an application layer, packet layer, WLAN protocol stack layers (e.g., a link or MAC layer), and / or WWAN protocol stack layers (e.g., a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a MAC layer). In some cases, at least one of the modems 512 (e.g., the WWAN modem) may be in communication with one or more of the other modems 512 (e.g., the WLAN modem and / or Bluetooth modem). For example, the processor 510 may be representative of at least one of the modems 512 in communication with one or more of the other modems 512.

[0090] The one or more modems 512 may include an intelligent hardware block or device such as, for example, an application-specific integrated circuit (ASIC) among other possibilities. The one or more modems 512 may generally be configured to implement a physical (PHY) layer. For example, the one or more modems 512 may be configured to modulate packets and to output the modulated packets to the radio 550 for transmission over a wireless medium. The one or more modems 512 is similarly configured to obtain modulated packets received by the radio 550 and to demodulate the packets to provide demodulated packets. In addition to a modulator and a demodulator, the one or more modems 512 may further include digital signal processing (DSP) circuitry, automatic gain control (AGC), a coder, a decoder, a multiplexer and a demultiplexer (not shown).

[0091] As an example, while in a transmission mode, the one or more modems 512 may obtain data from the processor 510. The data obtained from the processor 510 may be provided to a coder, which encodes the data to provide encoded bits. The encoded bits may be mapped to points in a modulation constellation (e.g., using a selected modulation and coding scheme) to provide modulated symbols. The modulated symbols may be mapped, for example, to spatial stream(s) or space-time streams. The modulated symbols may be multiplexed, transformed via an inverse fast Fourier transform (IFFT) block, and subsequently provided to DSP circuitry for transmit windowing and filtering. The digital signals may be provided to a digital-to-analog converter (DAC) 522. In certain aspects involving beamforming, the modulated symbols in the respective spatial streams may be precoded via a steering matrix prior to provision to the IFFT block.P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 20

[0092] The one or more modems 512 may be coupled to the radio 550 including a transmit (TX) path 514 (also known as a transmit chain) for transmitting signals via one or more antennas 518 and a receive (RX) path 516 (also known as a receive chain) for receiving signals via the antennas 518. When the TX path 514 and the RX path 516 share an antenna 518, the paths may be connected with the antenna via an interface 520, which may include any of various suitable RF devices, such as a switch, a duplexer, a diplexer, a multiplexer, and the like. As an example, the one or more modems 512 may output digital in-phase (I) and / or quadrature (Q) baseband signals representative of the respective symbols to the DAC 522.

[0093] Receiving I or Q baseband analog signals from the DAC 522, the TX path 514 may include a baseband filter (BBF) 524, a mixer 526 (which may include one or several mixers), and a power amplifier (PA) 528. The BBF 524 filters the baseband signals received from the DAC 522, and the mixer 526 mixes the filtered baseband signals with a transmit local oscillator (LO) signal to convert the baseband signal to a different frequency (e.g., upconvert from baseband to a radio frequency). In some aspects, the frequency conversion process produces the sum and difference frequencies between the LO frequency and the frequencies of the baseband signal. The sum and difference frequencies are referred to as the beat frequencies. Some beat frequencies are in the RF range, such that the signals output by the mixer 314 are typically RF signals, which may be amplified by the PA 528 before transmission by the antenna 518. The antennas 518 may emit RF signals, which may be received at the second wireless communications device 504. While one mixer 526 is illustrated, several mixers may be used to upconvert the filtered baseband signals to one or more intermediate frequencies and to thereafter upconvert the intermediate frequency signals to a frequency for transmission.

[0094] The RX path 516 may include a low noise amplifier (LNA) 530, a mixer 532 (which may include one or several mixers), and a baseband filter (BBF) 534. RF signals received via the antenna 518 (e.g., from the second wireless communications device 504) may be amplified by the LNA 530, and the mixer 532 mixes the amplified RF signals with a receive local oscillator (LO) signal to convert the RF signal to a baseband frequency (e.g., downconvert). The baseband signals output by the mixer 532 may be filtered by the BBF 534 before being converted by an analog-to-digital converter (ADC) 536 to digital I or Q signals for digital signal processing. The one or more modems 512P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 21may receive the digital I or Q signals and further process the digital signals, for example, demodulating the digital signals.

[0095] Certain transceivers may employ frequency synthesizers with a voltage-controlled oscillator (VCO) to generate a stable, tunable LO frequency with a particular tuning range. Thus, the transmit LO frequency may be produced by a frequency synthesizer 538, which may be buffered or amplified by an amplifier (not shown) before being mixed with the baseband signals in the mixer 526. Similarly, the receive LO frequency may be produced by the frequency synthesizer 538, which may be buffered or amplified by an amplifier (not shown) before being mixed with the RF signals in the mixer 532. Separate frequency synthesizers may be used for the TX path 514 and the RX path 516.

[0096] While in a reception mode, the one or more modems 512 may obtain digitally converted signals via the ADC 536 and RX path 516. As an example, in the one or more modems 512, digital signals may be provided to the DSP circuitry, which is configured to acquire a received signal, for example, by detecting the presence of the signal and estimating the initial timing and frequency offsets. The DSP circuitry is further configured to digitally condition the digital signals, for example, using channel (narrowband) filtering, analog impairment conditioning (such as correcting for I / Q imbalance), and applying digital gain to ultimately obtain a narrowband signal. The output of the DSP circuitry may be fed to the AGC, which is configured to use information extracted from the digital signals, for example, in one or more received training fields, to determine an appropriate gain. The output of the DSP circuitry also may be coupled with the demodulator, which is configured to extract modulated symbols from the signal and, for example, compute the logarithm likelihood ratios (LLRs) for each bit position of each subcarrier in each spatial stream. The demodulator may be coupled with the decoder, which may be configured to process the LLRs to provide decoded bits. The decoded bits from all of the spatial streams may be fed to the demultiplexer for demultiplexing. The demultiplexed bits may be descrambled and provided to a medium access control layer (e.g., the processor 510) for processing, evaluation, or interpretation.

[0097] The processor 510 and / or one or more modems 512 may control the transmission of signals via the TX path 514 and / or reception of signals via the RX path 516. In some aspects, the processor 510 and / or one or more modems 512 may be configured to perform various operations, such as those associated with any of theP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 22methods described herein. The processor 510 and / or the one or more modems 512 may include a microcontroller, a microprocessor, an application processor, a baseband processor, a MAC processor, a neural network processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device (PLD), discrete gate or transistor logic, discrete hardware components, or any combination thereof. In some cases, aspects of the processor 510 may be integrated with (incorporated in and / or shared with) the one or more modems 512, such as a microcontroller, a microprocessor, a baseband processor, a medium access control (MAC) processor, a digital signal processor, etc. For example, the processor 510 may be representative of a co-processor (e.g., a microprocessor) associated with the one or more modems 512, and the one or more modems 512 may be representative of an ASIC including the baseband processor, MAC processor, DSP, and / or neural network processor. The memory 540 may store data and program codes (e.g., computer-readable instructions) for performing wireless communications as described herein. The memory 540 may be external to the processor 510 and / or the one or more modems 512 (as illustrated) and / or incorporated therein.

[0098] FIG. 5 shows an example transceiver design. It will be appreciated that other transceiver designs or architectures may be applied in connection with aspects of the present disclosure. For example, while examples discussed herein utilize I and Q signals (e.g., quadrature modulation), those of skill in the art will understand that components of the transceiver may be configured to utilize any other suitable modulation, such as polar modulation. As another example, circuit blocks may be arranged differently from the configuration shown in FIG. 5, and / or other circuit blocks not shown in FIG. 5 may be implemented in addition to or instead of the blocks depicted.Aspects Related to Managing Bandwidth Edge Distortion

[0099] Filters play a crucial role in transmission (TX) chains (e.g., TX path 514) and reception (RX) chains (e.g., RX path 516), serving as one of their main components. The primary function of a filter is to allow the bandwidth (BW) allocated for a transmission to pass through the filter while rejecting frequencies outside this allocated BW. This functionality is vital to ensure that the transmitted signal remains within the designated BW and to suppress unwanted signal harmonics, which can arise due to non-linearities or phase noise effects associated with hardware components of the TX and RX chains. Commonly, Finite Impulse Response (FIR) filters are utilized within TX and RX chains P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 23due to their ease of implementation, flexibility, stability, and lower complexity. However, a significant drawback of FIR filters is their tendency to introduce distortion at edges of the allocated BW.

[0100] FIG. 6 illustrates an example frequency response graph 600 of a FIR filter, illustrating distortion that may occur at the edges of an allocated BW 602. As shown, the frequency response graph 600 includes the desired frequency response 604 of an ideal filter, serving as a reference for comparison.

[0101] The frequency response graph 600 further includes frequency responses for FIR filters with varying numbers of taps, specifically a 20-tap response 606 and a 50-tap response 608. Taps refer to the coefficients used in the FIR filter, which determine the filter's ability to approximate the desired frequency response. As shown, relative to the desired frequency response 604 of the ideal filter, a FIR filter with fewer taps (e.g., 20-tap response 606) exhibits more significant distortion at the BW edges compared to the filter with more taps (e.g., 50-tap response 608). As can be seen, the severity of this distortion becomes increasingly pronounced as the number of FIR filter taps decreases.

[0102] In some cases, however, advanced UEs may be able to address this challenge by employing FIR filters with longer lengths (e.g., greater number of taps), such as the 50-tap response shown in FIG. 6 or a greater number of taps. Increasing the number of taps helps to suppress distortion and achieve an error level that more closely aligns with the desired frequency response 604, thus improving overall performance.

[0103] Distortion at the BW edges is a common scenario that may also result from other factors beyond the inherent limitations of FIR filters. For instance, digital-to-analog (D2A) converters (e.g., DAC 522) contribute to distortion due to non-ideal reconstruction of continuous signals. Typically, D2A converters employ a zero-order hold (ZOH) method, which may lead to undesired signal attenuation at the BW edges. Similar to filtering distortion, advanced UEs may mitigate D2A-induced distortion by incorporating anti-drooping components to pre-compensate for this effect, thus preserving signal integrity across the BW.

[0104] Another contributor to BW edge distortion is impedance matching. Impedance matching is essential in electronic circuits and communication systems for maximizing power transfer and minimizing signal reflection when transmitting signals, thereby improving overall signal integrity. However, impedance matching is typically optimizedP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 24for the center carrier frequency of the BW. As a result, frequencies at the edges of the BW, which may be located significantly away from the center carrier frequency, often experience greater impairment compared to frequencies closer to the center carrier frequency. As a result, this non-uniform distortion can further degrade the performance of TX and RX chains at the BW edges.

[0105] As can be seen, distortion at the edges of the BW may arise from various factors. In some cases, advanced UEs may be able to suppress or mitigate this distortion, thereby reducing transmission errors to negligibly low levels. Additionally, certain wireless communication standards incorporate mechanisms to address distortion on BW edges. For example, these wireless communication standards may defines a guard band at the BW edges to help minimize these distortions. However, even with these measures in place, there are scenarios where distortion at the BW edges becomes the dominant noise or is non-negligible compared to other sources of noise and distortion. In such cases, the modulation and coding scheme (MCS) used for signal transmission may be controlled based on the portion of the BW with the poorest signal-to-distortion-and-noise ratio (SDNR), a measure that reflects the signal’s strength relative to the combined effects of distortion and noise and serves as a critical indicator of signal quality.

[0106] This issue is particularly relevant in the uplink (UL). According to current standards, each UE may be configured to indicate the maximum MCS order it can support for the entire BW based on an error vector magnitude (EVM) of its transmitted signal. The EVM represents the maximum error the UE can guarantee for its transmission and is inherently linked to SDNR. In some cases, when the EVM of a transmitted signal serves as the dominant noise floor, reflecting the poorest SDNR within the BW, this EVM may ultimately dictate the MCS that the UE can support across the entire BW. FIG.7 includes an example graph 700 illustrating an SDNR level 702 across an allocated BW 704.

[0107] As shown in FIG. 7, the SDNR level 702 varies across the allocated BW, typically achieving better (higher) levels near the center (e.g., / c) of the allocated BW 704. However, at the edges 706 of the allocated BW 704, SDNR levels often degrade due to the previously discussed distortion factors. For example, as illustrated, the center of the allocated BW 704 may be associated with a first SDNR level (e.g., SDNRi in decibels (dBs)), which may be correspond to a lower EVM. In contrast, the edges 706 of the allocated BW 704 may be associated with a second SDNR level (e.g., SDNR2), which is lower than the first SDNR level and may correspond to a higher EVM.P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 25

[0108] Despite the center of the allocated BW 704 having a better (e.g., higher) SDNR level than the edges 706, current wireless communication standards define a single EVM requirement per transport block, which is constrained by the lowest SDNR levels within the allocated BW 704, such as the second SDNR level (e.g., SDNR2) associated with the edges 706 of the allocated BW 704. As a result, the MCS used for UL transmissions by the UE may be limited by the poorest SDNR conditions, restricting overall performance. In other words, even though the higher SDNR levels (e.g., SDNRi) at the center of the allocated BW 704, along with the correspondingly lower EVM, may support a higher MCS, the UE may be constrained to use an MCS limited by the lower SDNR levels and higher EVM at the edges 706 of the allocated BW 704, resulting in a lower code rate and reduced overall throughput.

[0109] Accordingly, aspects of the present disclosure provide techniques for improving code rates and overall throughput in an allocated UL BW, especially in scenarios where SDNR levels and EVM may vary across different portions of the allocated UL BW. For example, in some cases, instead of reporting a maximum MCS or MCS order that the UE can support across the entire allocated UL BW (e.g., which would be greatly affected by its lowest SDNR level), these techniques may involve the UE reporting a plurality of different EVM guarantees for different portions of the allocated UL BW.

[0110] FIG. 8 includes an example graph 800 illustrating different SDNR levels that may be supported by the UE for different portions of an allocated UL BW 802 (e.g.,^). For example, as illustrated, the UE may be capable of supporting a first SDNR level (e.g., SDNRi) in a center portion 804 of the allocated UL BW 802, defined relative to a center frequency fc. Specifically, as shown, the center portion 804 may span frequencies from -fi+fc to fi+fc of the allocated UL BW 802. Additionally, as illustrated, relative to the first SDNR level, the UE may only be capable of supporting a second SDNR level (e.g., SDNR2) in edge portions 806 of the allocated UL BW 802. Specifically, as shown in FIG.8, the edge portions 806 may span frequencies from -fz+fc to -fi+fc and from fi+fcto fz+fc of the allocated UL BW 802.

[0111] Accordingly, in some cases, due to the differing SDNR levels, the UE may be configured to transmit a first message, to a network entity, indicating a plurality of modulation-related parameters for different portions of the UL BW. For example, in some cases, the first message may indicate a first EVM (e.g., EVMi), a first MCS, or a firstP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 26MCS order for the center portion 804 of the allocated UL BW 802 corresponding to the first SDNR level (e.g., SDNRi). Additionally, the first message may indicate a second EVM (e.g., EVM2), a second MCS, or a second MCS order for the edge portions 806 of the allocated UL BW 802 corresponding to the second SDNR level (e.g., SDNR2). In some cases, by indicating different EVMs that the UE is able to guarantee for the different portions of the allocated UL BW 802, the network entity may configure the UE with different MCSs for the different portions of the allocated UL BW 802. For example, in some cases, the UE may receive configuration information from the network entity indicating a plurality of MCSs for UL transmissions by the UE, including a first MCS for the center portion 804 of the allocated UL BW 802 and a second MCS for the edge portions 806 of the allocated UL BW 802. The UE may then use the plurality of MCSs when transmitting the UL transmissions. In some cases, the first MCS for the center portion 804 may be higher than the second MCS for the edge portions 806, allowing the UE to transmit the UL transmissions in the center portion 804 with a higher code rate and higher throughput relative to UL transmissions transmitted in the edge portions 806.

[0112] While the techniques presented above describe the UE indicating two modulation-related parameters (e.g., the first EVM and the second EVM) for different portions of the allocated UL BW 802, it should be appreciated that the UE may be configured to indicate more than modulation-related parameters for different portions of the allocated UL BW 802. For example, rather than having one center portion 804, there may be multiple center portions of the allocated UL BW 802, and the UE may be configured to indicate an EVM for each of the multiple center portions. In some cases, the first message indicating the plurality of modulation-related parameters may be sent at the beginning of communication between the UE and the network entity (e.g., during a random access channel (RACH) procedure in a media access control -control element (MAC-CE)) or upon a request from the network entity. In some cases, the first message may be sent in a table form, as shown below in Table 1. In some cases, each of the UE and the network entity may periodically request to update the table including the plurality of modulation-related parameters. Additional details regarding the techniques presented above will be described below with respect to FIG. 9.< < <P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 27Table 1: EVMs for different portions of an UL BWExample Operations of Entities in a Communications Network

[0113] FIG. 9 depicts a process flow including operations 900 for communications in a network between a network entity 902 and a user equipment (UE) 904. In some aspects, the network entity 902 may be an example of the BS 102 depicted and described with respect to FIG. 1 and 3 or a disaggregated base station depicted and described with respect to FIG. 2. Similarly, the UE 904 may be an example of UE 104 depicted and described with respect to FIG. 1 and 3. However, in other aspects, UE 904 may be another type of wireless communications device and network entity 902 may be another type of network entity or network node, such as those described herein.

[0114] As shown, operations 900 begin at 910 with the UE 904 receiving, from the network entity 902, first configuration information indicating an uplink (UL) bandwidth (BW) for transmitting UL transmissions.

[0115] At 912, the UE 904 receives, from the network entity 902, a message requesting capability information from the UE 904 regarding whether the UE 904 is capable of supporting different modulation-related parameters for different portions of the UL BW. In some cases, the message requesting the capability information may be received from the network entity 902 at the beginning of communication between the network entity 902 and UE 904, such as during a RACH procedure, cell search and synchronization, system information acquisition, or another procedure occurring at the beginning of communication between the network entity 902 and the UE 904. In some cases, the message requesting the capability information may comprise a MAC-CE or a message transmitted on a physical downlink control channel (PDCCH) (e.g., downlink control information (DCI)).

[0116] At 914, the UE 904 transmits, to the network entity 902, the capability information indicating that the UE 904 is capable of supporting the different modulation-related parameters for different portions of the UL BW.

[0117] At 916, based on the capability information indicating that the UE is capable of supporting the different modulation-related parameters, the UE 904 receives, from the network entity 902, second configuration information indicating time and frequency resources for transmitting a request to use different modulation-related parameters for different portions of the UL BW. Additionally, in some cases, the time and frequencyP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 28resources may be used for transmitting an indication of a quantity of the different modulation-related parameters that are requested to be used by the UE. For example, in some cases, the network entity 902 may limit the quantity of the different modulation-related parameters to a particular quantity, such as four different modulation-related parameters. Further, in some cases, in some cases, the second configuration information indicating the time and frequency resources may also indicate a periodicity associated with the time and frequency resources. For example, the periodicity may allow the UE 904 to periodically update the request to use the different modulation-related parameters and the quantity of the different modulation-related parameters that are being requested by the UE 904. In some cases, the periodicity may be indicated as a number of symbols, a number of slots, or a number of frames. For example, in some cases, the periodicity may be every 40 slots.

[0118] At 918, the UE 904 transmits, to the network entity 902 using the indicated time and frequency resources, the request to use the different modulation-related parameters for different portions of the UL BW and the indication of the quality of the different modulation-related parameters that are requested to be used by the UE. In some cases, the UE 904 may transmit the request to use the different modulation-related parameters for the different portions of the UL BW in order to reduce power consumption. For example, in some cases, when the UE 904 wishes to conserve power, the UE 904 may enter a power saving mode (e.g., a low-battery mode) and may transmit the request to use the different modulation-related parameters at 918.

[0119] At 920, the UE 904 receives, from the network entity 902 after transmitting the request to use the different modulation-related parameters, third configuration information including an indication of a quantity of modulation-related parameters for the UE 904 to include in a plurality of modulation-related parameters to be transmitted to the network entity 902. In other words, the third configuration information may indicate to the UE 904 how many modulation-related parameters to report to the network entity 902. Additionally, in some cases, the third configuration information may indicate to the UE 904 to include, in the plurality of modulation-related parameters, one of a plurality of different error vector magnitudes (EVMs) or a plurality of different modulation and coding schemes (MCSs). In other words, the third configuration information may instruct the UE 904 to report either EVMs or MCSs when transmitting the plurality of modulation-related parameters to the network entity 902. Additionally, in some cases, the thirdP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 29configuration information may include time and frequency resources for transmitting a message indicating the plurality of modulation-related parameters.

[0120] At 922, the UE 904 transmits, to the network entity 902, a message indicating the plurality of modulation-related parameters for different portions of the UL BW. In some cases, the UE 904 may transmit this message using the time and frequency resources indicated in the third configuration information.

[0121] At 924, the UE 904 may receive, from the network entity 902 after transmitting the message indicating the plurality of modulation-related parameters, fourth configuration information indicating a plurality of MCSs for the different portions of the UL BW.

[0122] At 926, the UE 904 may transmit, to the network entity 902, the UL transmissions in the UL BW using the plurality of MCSs.

[0123] In some cases, the plurality of modulation-related parameters transmitted to the network entity 902 at 922 may comprise at least one of a plurality of different EVMs for the different portions of the UL BW or a plurality of different MCSs for the different portions of the UL BW. For example, in some cases, the plurality of modulation-related parameters include, at least, a first modulation-related parameter for a center portion of the UL BW and a second modulation-related parameter for edge portions of the UL BW. It should be appreciated, however, that the plurality of modulation-related parameters may include more than two modulation-related parameters for the different portions of the UL BW.

[0124] In some cases, the first modulation-related parameter comprises a first MCS for the center portion of the UL BW. In some cases, the second modulation-related parameter comprises a second MCS for the edge portions of the UL BW. In some cases, due to distortion at the edge portions of the UL BW, the first MCS for the center portion may be higher than the second MCS for the edge portions.

[0125] In some cases, the first modulation-related parameter comprises a first EVM for the center portion of the UL BW, such as EVMi corresponding to the center portion 804 described above with respect to FIG.8. In some cases, the second modulation-related parameter comprises a second EVM for the edge portions of the UL BW, such as EMV2 corresponding to the edge portions 806 described above with respect to FIG. 8. In someP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 30cases, due to distortion at the edge portions of the UL BW, the first EVM for the center portion may be lower than the second EVM for the edge portions.

[0126] In some cases, a less strict EVM guarantee (e.g., a higher EVM) for the edge portions of the UL BW may allow the UE 904 to reduce power consumption associated with digital filtering as well as reduce latency associated with transmitting UL transmissions. In some cases, the UE 904 may be configured to select a less strict EVM for the edge portions of the UL BW by shortening its FIR length at the expense of less accurate filtering at the edge portions of the UL BW. For example, as discussed above, an accuracy of the filtering, mainly at the edge portions of the UL BW, may be improved as the filter length (e.g., number of FIR taps) increases. However, as the filter length or number of FIR taps increases, power consumption associated with filtering may also increase. Accordingly, in some cases, to reduce power consumption, the UE 904 may instead be configured to reduce the length of its filter (e.g., reduce the number of FIR taps) associated with the edge portions of the UL BW, which may result in a higher EVM (e.g., less strict EVM) for the edge portions of the UL BW. In some cases, to reduce the power consumption, the UE 904 may be configured to enter a power saving mode, and transmit the message at 922 indicating the plurality of modulation-related parameters for the different portions of the UL BW in response to entering the power saving mode.

[0127] In some cases, the UE 904 may be configured to generate a table which translates the length of its FIR to a resulting EVM. For example, as shown at 921, the UE 904 may be configured to generate a table, such as Table 2 below, including a plurality of different EVMs and a plurality of distinct quantities of FIR taps.P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 31Table 2: EVMs for different quantities of FIR taps

[0128] As can be seen in Table 2, each different EVM of the plurality of different EVMs may correspond to a different quantity of FIR taps of the plurality of distinct quantities of FIR taps. For example, 10 FIR taps may correspond to an EVM of -20.8, while 30 FIR taps may correspond to an EVM of -29.4, and so on. As discussed above, a lower number of FIR taps may allow the UE to conserve power, albeit at the expense of a higher EVM and less accurate filtering. Accordingly, in some cases, the UE 904 may use the generated table (e.g., Table 2 or a similar table) to aid in selecting an EVM to indicate to the network entity 902 for a portion of the UL BW according to a FIR length (e.g., number of FIR taps) that the UE 904 wishes to toggle to.

[0129] For example, as noted above, the second modulation-related parameter of the plurality of modulation-related parameters may comprise a second EVM for the edge portions of the UL BW. Accordingly, in some cases, the UE 904 may be configured to select at least the second EVM for the edge portions of the UL BW from the generated table. For example, in some cases, when the UE 904 wishes to conserve power (e.g., due to entering a low-battery or low-power mode), the UE 904 may select the second EVM for the edge portions of the UL BW to be -20.8 dB and may also reduce a quantity of FIR taps to 10. In contrast, when the UE 904 wishes to have more accurate filtering in the edge portions, the UE 904 may select the second EVM for the edge portions to be -29.4 dB may also increase the quantity of FIR taps to 30, as an example.

[0130] As noted above, the UE 904 may be configured to transmit UL transmissions to the network entity 902 at 926. In some cases, transmitting the UL transmissions to the network entity 902 may include transmitting a first UL transmission in one of the edge portions of the UL BW using the quantity of FIR taps corresponding to the second EVM selected from the table. For example, when the second EVM for the edge portions of the UL BW is selected to be -20.8 dB (e.g., to reduce power consumption), the UE 904 may be configured to transmit the first UL transmission in one of the edge portions of the UL BW using 10 FIR taps.

[0131] In some cases, the UE 904 may also use the generated table to update at least the second EVM for the edge portions of the UL BW. In some cases, at least the second EVM for the edge portions (and / or the first EVM for the center portion) may be updatedP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 32in various scenarios, for example, when the UE 904 enters a low-battery or low-power mode (e.g., power saving mode), due to certain cell restrictions associated with the network entity 902, and other scenario.

[0132] In some cases, to update an EVM associated with the edge portions of the UL BW, after transmitting the message indicating the plurality of modulation-related parameters (e.g., including the second EVM for the edge portions of the UL BW), the UE 904 may be configured select a third EVM for the edge portions of the UL BW. In some cases, the third EVM may be higher than the second EVM. In such cases, a quantity of FIR taps corresponding to the third EVM selected from the table may be lower than a quantity of FIR taps corresponding to the second EVM selected from the table. Further, in some cases, after selecting the third EVM, the UE 904 may update the EVM for the edge portions at the network entity 903 by transmitting another message, to the network entity 902, indicating the third EVM for the edge portions of the UL BW.

[0133] In some cases, the network entity 902 may confirm or deny an EVM that is indicated for a particular portion of the UL BW. For example, in some cases, the UE 904 may receive, from the network entity 902, a message that confirms use of the third EVM for the edge portions of the UL BW. In such cases, the UE 904 may transmit a second UL transmission in one of the edge portions of the UL BW using the quantity of FIR taps corresponding to the third EVM selected from the table.

[0134] In some cases, however, the UE 904 may receive a message from the network entity 902 that denies use of the third EVM for the edge portions of the UL BW. In some cases, this message or another message may indicate a fourth EVM for the edge portions of the UL BW. In such cases, the UE 904 may transmit a third UL transmission in one of the edge portions using a quantity of FIR taps corresponding to the fourth EVM in the table.

[0135] In some cases, in addition to allowing the UE 904 to reduce power consumption, as described above, the plurality of modulation-related parameters for the different portions of the UL BW may also help to improve a data rate and reliability of the UL transmissions transmitted in the UL BW. For example, in some cases, the network entity 902 may configure multiple modulation orders corresponding to the different portions of the UL BW. For example, in some cases, the UE 904 may receive, from the network entity 902 after transmitting the message indicating the plurality of modulation-P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 33related parameters for the different portions of the UL BW, fifth configuration information indicating a plurality of modulation orders for the different portions of the UL BW. In some cases, the fifth configuration information may further indicates which modulation order of the plurality of modulation orders corresponds to which portion of the UL BW of the different portions of the UL BW. For example, in some cases, the fifth configuration information may include a first modulation order and a second modulation order. Further, in some cases, the fifth configuration information may indicate that the first modulation order corresponds to the center portion of the UL BW and may indicate that the second modulation order corresponds to the edge portions of the UL BW. In some cases, the first modulation order corresponding to the center portion of the UL BW may be higher than the second modulation order corresponding to the UL BW.

[0136] In some cases, the UE 904 may send a message to the network entity 902 confirming or acknowledging use of the plurality of modulation orders for the different portions of the UL BW. After transmitting the message confirming the use of the plurality of modulation orders, the UE 904 may modulate the UL transmissions transmitted at 926 according to the plurality of modulation orders. In some cases, the first modulation order corresponding to the center portion of the UL BW may be higher than the second modulation order corresponding to the UL BW. In such cases, because the first modulation order corresponding to the center portion of the UL BW is higher, the UL transmissions transmitted in the center portion of the UL BW will benefit from improved SNR and an increased data rate relative to UL transmissions transmitted in the edge portions of the UL BW corresponding to the (lower) second modulation order.

[0137] In some cases, the network entity 902 may configure the UE 904 to interleave resource blocks (RBs) of the UL transmissions from the edge portions of the UL BW with RBs from the center portion of the UL BW, which may result in equal quality across code blocks (CBs) of the UL transmission and improve an average SNR of the UL transmission. For example, in some cases, the UL transmissions may be transmitted at 926 using a plurality of RBs included in the UL BW. Further, in some cases, the plurality of RBs include one or more RBs included within edge portions of the UL BW and one or more RBs included within a center portion of the UL BW.

[0138] Additionally, in some cases, the UE 904 may receive, from the network entity 902 after transmitting the message indicating the plurality of modulation-related parameters for the different portions of the UL BW, sixth configuration informationP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 34configuring the UE 906 to interleave the one or more resource blocks included within the edge portions of the UL BW with the one or more resource blocks included within the center portion of the UL BW. Thereafter, when transmitting the UL transmissions at 926, the UE 904 may be configured to interleave the one or more resource blocks included within the edge portions of the UL BW with the one or more resource blocks included within the center portion of the UL BW to obtain a set of interleaved RBs. In such cases, transmitting the UL transmissions at 926 may include transmitting the UL transmissions using the set of interleaved RBs.

[0139] In some cases, the sixth configuration information may also indicate an MCS for transmitting the UL transmissions using the set of interleaved RBs. In some cases, the MCS may be based on an average expected channel capacity of the UL BW associated with the interleaving. For example, in some cases, the network entity 902 may evaluate the average expected channel capacity across the whole UL BW, which due to the interleaving, may be expected to be equal across the CBs of the UL transmissions. The network entity 902 may then determine the MCS for transmitting the UL transmissions according to the average expected channel capacity of the UL BW. In some cases, this may enable sending more bits in each UL transmission of the UL transmissions and may also improve the data rate and the spectral efficiency of the UL transmissions.

[0140] In some cases, the network entity 902 may schedule data which is tagged as most important to be protected by portions of the UL BW that are associated with good EVM guarantees and improve the reliability of that transmitted data. For example, in some cases, the UE 904 may receive, from the network entity 902, scheduling information scheduling one or more UL transmissions including higher priority information within the center portion of the UL BW based on the first EVM for the center portion being lower than the second EVM for the edge portions. In some cases, the higher priority information may include at least one of channel state information (CSI), scheduling requests (SRs), hybrid automatic repeat request (HARQ) feedback, beam management feedback, or uplink data associated with ultra-reliable low-latency communication (URLLC).Example Operations

[0141] FIG. 10 shows an example of a method 1000 of wireless communication by a user equipment (UE), such as a UE 104 of FIGS. 1 and 3.P+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 35

[0144] Method 1000 then proceeds to step 1015 with receiving, from the network entity after transmitting the first message indicating the plurality of modulation-related parameters, second configuration information indicating a plurality of modulation and coding schemes (MCSs) for the different portions of the UL BW.

Similarly, “a memory,” “at least one memory” or “one or more memories” generally refers to a single memory configured to store data and / or instructions, multiple memories configured to collectively store data and / or instructions.

[0276] In some cases, rather than actually transmitting a signal, an apparatus (e.g., a wireless node or device) may have an interface to output the signal for transmission. For example, a processor may output a signal, via a bus interface, to a radio frequency (RF) front end for transmission. Accordingly, a means for outputting may include such an interface as an alternative (or in addition) to a transmitter or transceiver. Similarly, rather than actually receiving a signal, an apparatus (e.g., a wireless node or device) may have an interface to obtain a signal from another device. For example, a processor may obtain (or receive) a signal, via a bus interface, from an RF front end for reception. Accordingly, a means for obtaining may include such an interface as an alternative (or in addition) to a receiver or transceiver.

[0277] While the present disclosure may describe certain operations as being performed by one type of wireless node, the same or similar operations may also be performed by another type of wireless node. For example, operations performed by a user equipment (UE) may also (or instead) be performed by a network entity (e.g., a baseP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 57station or unit of a disaggregated base station). Similarly, operations performed by a network entity may also (or instead) be performed by a UE.

[0278] Further, while the present disclosure may describe certain types of communications between different types of wireless nodes (e.g., between a network entity and a UE), the same or similar types of communications may occur between same types of wireless nodes (e.g., between network entities or between UEs, in a peer-to-peer scenario). Further, communications may occur in reverse order than described.

[0279] As used herein, a phrase referring to “at least one of’ a list of items refers to any combination of those items, including single members. As an example, “at least one of: a, b, or c” is intended to cover a, b, c, a-b, a-c, b-c, and a-b-c, as well as any combination with multiples of the same element (e.g., a-a, a-a-a, a-a-b, a-a-c, a-b-b, a-c-c, b-b, b-b-b, b-b-c, c-c, and c-c-c or any other ordering of a, b, and c).

[0280] As used herein, the term “determining” encompasses a wide variety of actions. For example, “determining” may include calculating, computing, processing, deriving, investigating, looking up (e.g., looking up in a table, a database or another data structure), ascertaining and the like. Also, “determining” may include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory) and the like. Also, “determining” may include resolving, selecting, choosing, establishing and the like.

[0281] The methods disclosed herein comprise one or more actions for achieving the methods. The method actions may be interchanged with one another without departing from the scope of the claims. In other words, unless a specific order of actions is specified, the order and / or use of specific actions may be modified without departing from the scope of the claims. Further, the various operations of methods described above may be performed by any suitable means capable of performing the corresponding functions. The means may include various hardware and / or software component(s) and / or module(s), including, but not limited to a circuit, an application specific integrated circuit (ASIC), or processor.

[0282] The following claims are not intended to be limited to the aspects shown herein, but are to be accorded the full scope consistent with the language of the claims. Within a claim, reference to an element in the singular is not intended to mean “one and only one” unless specifically so stated, but rather “one or more.” Unless specifically stated otherwise, the term “some” refers to one or more. No claim element is to be construedP+S Ref. No.: QUAL / 2500286PCQualcomm Ref. No.: 2500286WO 58under the provisions of 35 U.S.C. §112(f) unless the element is expressly recited using the phrase “means for”.
