[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. Consequently, there exists a need for further improvements in wireless communications systems to overcome the aforementioned technical challenges and others.Dinsmore Ref. QCM2500942WOQualcomm Ref.

[0023] Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer-readable mediums for adaption configuration for a periodic or semi-persistent signal.

[0024] Some wireless communication systems may support an adaptation scheme that enables reconfiguration of a bandwidth part (BWP) via downlink control information (DCI), without impacting a DCI format. The adaptation scheme can enable fast switching between configurations for the BWP (e.g., switching configurations for a next slot). Configuration parameters of the BWP that can be adapted according to the adaptation scheme include, for example, a maximum bandwidth, a maximum rank, a minimum processing timeline, or a search space (SS) periodicity. According to the adaptation scheme, DCI can be used to indicate a state in which the UE is to operate, with the state being defined according to values of the configuration parameters. For example, a first state may be a “high power” state that is defined by a first (larger) maximum bandwidth, a first (larger) maximum rank, a first (shorter) minimum processing timeline, and a first SS periodicity, while a second “low power” state may be defined by a second (smaller) bandwidth, a second (smaller) maximum rank, a second (longer) minimum processing timeline, and a second SS periodicity. Here, the adaptation scheme may allow the UE to switch between operation in accordance with the first state and operation in accordance with the second state via DCI, which provides faster switching as compared to switching between BWPs. Further, such an implementation of the adaptation scheme provides UE power savings by, for example, enabling the UE to operate in the “low power” state when possible.

[0025] Additionally, a wireless communications system may utilize a number of periodic or semi-persistent signals in support of wireless communications. As used herein, a periodic or semi-persistent signal refers to a signal that the UE is expected to transmit or receive without an explicit grant for each transmission or reception of the signal. Examples of a periodic or semi-persistent signal include a downlink semi-persistentDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO5 / 62scheduling (SPS) physical downlink shared channel (PDSCH) signal (e.g., periodic reception of a PDSCH that can be activated via DCI), an uplink configured grant physical uplink shared channel (PUSCH) signal (e.g., a periodic transmission of a PUSCH that can be activated via radio resource control (RRC) signaling or DCI), a periodic physical uplink control channel (PUCCH) signal, a periodic or semi -persistent channel state information reference signal (CSI-RS) (e.g., a periodic or semi-persistent reception of a CSI-RS that can be activated via RRC signaling or a medium access control (MAC) control element (CE)), a periodic tracking reference signal (TRS), a periodic sounding reference signal (SRS) transmission, a periodic downlink positioning reference signal (PRS), or a synchronization signal block (SSB), among other examples. As noted above, the UE may be expected to transmit or receive these periodic or semi-persistent signals without an explicit grant for each transmission or reception of a given signal.

[0026] With respect to the adaptation scheme described above, one approach to handling periodic or semi-persistent signals is to make periodic or semi-persistent signals exempt from scheduling restrictions introduced by the adaptation scheme. In practice, exemption from scheduling restrictions introduced by the adaptation scheme means that a periodic or semi-persistent signal is limited to one configuration in a BWP. Thus, in operation, a UE would be configured to operate according to a particular set of configuration parameters (e.g., a set of configuration parameters associated with a high power state) for communication of a periodic or semi-persistent signal, even though the UE may be configured to operate in accordance with another set of configuration parameters (e.g., a set of configuration parameters associated with a low power state) for communication of other signals. Such operation is possible because the UE is aware of the timing of the periodic or semi-persistent signal (due to the periodic or semi-persistent nature of the signal) and, therefore, may have sufficient time to switch configurations in order to communicate the periodic or semi-persistent signal in accordance with the particular configuration. Other signals in the same slot as the periodic or semi-persistent signal could also be exempt from such scheduling restrictions.

[0027] However, handling periodic or semi-persistent signals in this manner may be inefficient. For example, because adaptive configuration of a BWP in association with communication of a periodic or semi-persistent signal is not provided for under the current adaptation scheme, UE power savings may not be optimized (e.g., a UE may waste power as result of using the single particular configuration for the periodic or semi-Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO6 / 62persistent signal). Therefore, a technical problem associated with the adaptation scheme that enables reconfiguration of a BWP via DCI may include a lack of compatibility with respect to communication of periodic or semi-persistent signals, which can degrade UE power savings achieved by the adaptation scheme.

[0028] Aspects described herein may overcome the aforementioned technical problem(s), for example, by providing adaptive configuration for a periodic or semi-persistent signal. In some aspects, a UE may identify (e.g., receive, select, determine, or the like) an adaptation configuration associated with a communication (e.g., a transmission or a reception) of a periodic or semi-persistent signal. The adaptation configuration may indicate a limitation or boundary for one or more configuration parameters associated with the communication of the periodic or semi-persistent signal, such as a maximum bandwidth, a maximum rank, a minimum processing timeline, or a maximum SS periodicity. The UE may then perform the communication of the periodic or semi-persistent signal during operation according to the set of configuration parameters indicated in the adaptation configuration.

[0029] Certain techniques for adaptive configuration for a periodic or semi-persistent signal described herein may provide various beneficial technical effects and / or advantages. The techniques for adaptive configuration for a periodic or semi-persistent signal may enable improved wireless communications performance, such as increased UE power savings. The increased UE power savings may be attributable to the techniques and apparatuses described herein, for example, due to providing compatibility of an adaptation scheme with communication of periodic or semi-persistent signals. Further, certain techniques for adaptive configuration for a periodic or semi-persistent signal described herein enable a network to cancel or override a configuration switch associated with a BWP in a dynamic manner, thereby increasing flexibility and control by the network with respect to adaptive configuration for the periodic or semi-persistent signal.Introduction to Wireless Communications Networks

[0030] 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, 5G, 6G, and / or other generations of wireless technologies, aspects of the present disclosure may likewise be applicable to other communications systems and standards not explicitly mentioned herein.Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO7 / 62

[0031] FIG. 1 depicts an example of a wireless communications network 100, in which aspects described herein may be implemented.

[0032] 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.). As such communications devices are part of wireless communications network 100, and facilitate wireless communications, such communications devices may be referred to as wireless communications devices. 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 may include terrestrial aspects, such as ground-based network entities (e.g., BSs 102), and non-terrestrial aspects (also referred to herein as non-terrestrial network entities). A non-terrestrial network entity may include satellite 140, which may be an example of an aerial or space-borne platform. In some examples, satellite 140 may include one or more network entities on-board (e.g., one or more BSs) capable of communicating with other network elements (e.g., terrestrial BSs) and UEs. For example, satellite 140 may be implemented according to a regenerative architecture (also referred to as a non-transparent architecture), and a gNB implemented at satellite 140 may implement higher-layer network functions. As another example, satellite 140 may be implemented according to a transparent architecture, and may perform a physical or other lower-layer repeater function for UEs and a network entity (such as a gateway associated with the satellite 140).

[0033] 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 or a 5G Core (5GC) network 190, which interoperate to provide communications services over various communications links, including wired and wireless links. In some aspects, a core network, such as a 6G core, may implement a converged service-based architecture. In a converged service-based architecture, functions traditionally split between a core network (such as 5GC network 190) and a radio access network (RAN) (such as BS 102) may be implemented at a single network entity. For example, a mobility network entity may perform both core network functions and RAN functions related to mobility of UEs 104 attached to the wireless communications network 100. “NetworkDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO8 / 62entity” can refer to a BS 102, a network entity of EPC 160 or 5GC network 190, or a network entity of a converged service-based architecture.

[0034] FIG. 1 depicts various example UEs 104. UE 104 may include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a Global Positioning System device, a multimedia device, a video device, a digital audio player, a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, an Internet of Things (loT) device, an always on (AON) device, an edge processing device, a data center, or another similar device. A UE 104 may also be referred to as a mobile device, a wireless device, a station, a mobile station, a subscriber station, a mobile subscriber 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.

[0035] BSs 102 wirelessly communicate with (e.g., transmit signals to or receive signals from) UEs 104 via communications links 120. A communications link 120 between a BS 102 and a UE 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. A communications link 120 may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity in various aspects.

[0036] ABS 102 may include aNodeB, an enhanced NodeB (eNB), a next generation enhanced NodeB (ng-eNB), a next generation NodeB (gNB or gNodeB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a transmission reception point (TRP), a radio unit (RU), a distributed unit (DU), or the like. A given BS 102 may provide communications coverage for a coverage area 110, which may sometimes be referred to as a cell, and which may overlap another coverage area 110 (e.g., a small cell provided by a BS 102z) may have a coverage area 110zthat overlaps the coverage area 110 of a macro cell). A BS 102 may, for example, provide communications coverage for a macro cell (covering a relatively large geographic area), a pico cell (covering a relatively smaller geographic area, such as a sports stadium), a femto cell (covering a relatively smaller geographic area, such as a home), or another type of cell.Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO9 / 62

[0037] The term “cell” may refer to a portion, partition, or segment of wireless communication coverage served by a network entity within a wireless communications network 100. A cell may have geographic characteristics, such as a geographic coverage area, as well as radio frequency characteristics, such as time and / or frequency resources dedicated to the cell. For example, a specific geographic coverage area may be covered by multiple cells employing different frequency resources (e.g., bandwidth parts) and / or different time resources. As another example, a specific geographic coverage area may be covered by a single cell. In some contexts (e.g., a carrier aggregation scenario and / or multi-connectivity scenario), the terms “cell” or “serving cell” may refer to or correspond to a specific carrier frequency (e.g., a component carrier) used for wireless communications, and a “cell group” may refer to or correspond to multiple carriers used for wireless communications. As examples, in a carrier aggregation scenario, a UE may communicate on multiple component carriers corresponding to multiple (serving) cells in the same cell group, and in a multi-connectivity (e.g., dual connectivity) scenario, a UE may communicate on multiple component carriers corresponding to multiple cell groups.

[0038] 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 DUs, one or more RUs, a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC), or aNon-Real Time (Non-RT) RIC, to name a few examples. In another example, various aspects of a base station may be virtualized. 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. Implementing a base station in this fashion may provide efficiency gains by enabling cloud-based implementation of certain (e.g., non-time-sensitive) higher-layer functions while physical-layer or other lower-layer functions can be implemented at or in proximity to a geographic coverage area of a corresponding cell. In some aspects, a base station including components that are located at various physical locations may be referred to as having a disaggregated RAN architecture, such as an Open RAN (O-RAN) or VirtualizedDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO10 / 62RAN (VRAN) architecture. FIG.2 depicts and describes an example disaggregated RAN architecture.

[0039] Different BSs 102 within wireless communications network 100 may also be configured to support different radio access technologies, such as 3G, 4G, 5G, and / or 6G. 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., 5GNR 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 the 5GC 190) with each other over third backhaul links 134 (e.g., an X2 or XN interface), which may be wired or wireless.

[0040] 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, the Third Generation Partnership Project (3 GPP) currently defines Frequency Range 1 (FR1) as including 410 MHz - 7125 MHz, which is often referred to (interchangeably) as “Sub-6 GHz”. Similarly, 3 GPP 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.

[0041] A communications links 120 may be through one or more carriers, which may have different bandwidths (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, and / or other bandwidths), 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).Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO11 / 62

[0042] 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., base station 180 in FIG.1) may utilize beamforming (indicated by reference number 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 abeamformed 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 perform beam training to determine suitable 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.

[0043] Wireless communications network 100 may include a Wi-Fi access point (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.

[0044] Certain UEs 104 may communicate with each other using device-to-device (D2D) communications link 158. In some examples, 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). D2D communications link 158 may be implemented using a variety of technologies, such as a radio access technology (e.g., 5G, ProSe sidelink), a WiFi technology, a Bluetooth technology, or the like.

[0045] EPC 160 may include various functional components, such as 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. MME 162 may be in communication with a Home Subscriber Server (HSS) 174. MME 162 is a control node that processes signaling between the UEs 104 and the EPC 160. Generally, MME 162 provides bearer and connection management.Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO12 / 62

[0046] Generally, user Internet protocol (IP) packets are transferred through Serving Gateway 166. Serving gateway 166 is connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation as well as other functions. PDN Gateway 172 and 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.

[0047] 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.

[0048] 5GC 190 may include various functional components, such as 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.

[0049] AMF 192 is a control node that processes signaling between UEs 104 and the 5GC 190. AMF 192 provides, for example, quality of service (QoS) flow and session management.

[0050] IP packets are transferred through UPF 195, which is connected to the IP Services 197. UPF 195 may provide 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.

[0051] 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 core network entity, or a sidelink node, to name a few examples.

[0052] FIG. 2 depicts an example disaggregated base station 200 architecture. The disaggregated base station 200 architecture may include one or more CUs 210 that can communicate directly with a core network 220 or other CUs 210 via a backhaul link (suchDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO13 / 62as backhaul link 134), 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 E2 link, a Non- 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 DUs 230 via respective midhaul links, such as an Fl interface. The DUs 230 may communicate with one or more RUs 240 via respective fronthaul links. The RUs 240 may communicate with respective UEs 104 via one or more radio frequency (RF) access links (such as communication link 120). In some implementations, a UE 104 may be simultaneously served by multiple RUs 240.

[0053] 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 a processor or controller providing instructions to the 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 a transceiver (such as a RF transceiver), configured to receive or transmit signals, or both, over a wireless transmission medium.

[0054] 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 for network control and signaling.Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO14 / 62

[0055] The DU 230 may be or 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 3rd Generation 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.

[0056] 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.

[0057] 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 canDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO15 / 62communicate 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 DUs 230 and / or one or more RUs 240 via an 01 interface. The SMO Framework 205 also may include aNon-RT RIC 215 configured to support functionality of the SMO Framework 205.

[0058] 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.

[0059] 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).

[0067] UE 304 may be an example of UE 104. As shown, UE 304 includes a processing system 316. For example, UE 304 may include one or more chips, SoCs, SiPs, chipsets, packages, or devices that individually or collectively constitute or comprise aDinsmore Ref. QCM2500942WOQualcomm Ref.

Further, UE 304 includes one or more antennas 322, one or more transceivers 324, and / or other components that enable wireless transmission and reception of data.

[0068] The one or more processors 318 may include one or multiple processors, microprocessors, processing units (such as CPUs, GPUs, NPUs (also referred to as neural network processors or DLPs) and / or DSPs), processing blocks, ASICs, PLDs (such as FPGAs), or other discrete gate or transistor logic or circuitry (any one or more of which may be generally referred to herein individually as a “processor” or collectively as “the processor” or “the processor circuitry”). One or more of the processors may be individually or collectively configurable or configured to perform various functions or operations described herein. In some aspects, the processing system 316 may perform processing (such as digital signal processing) of data, control information, or signals received or transmitted by a network entity. For example, the processing system 316 may include a coder, a decoder, a multiplexer, a demultiplexer, a transmit MIMO processor, a transmit processor, a receive processor, a receive MIMO detector, an automatic gain control component, or the like.

[0069] As shown, in some examples, the one or more processors 318 may include one or more modems 326, one or more application processors (APs) 328, one or more Al processors 330, a combination thereof, and / or another form of processor.

[0070] The one or more modems 326 may include a digital signal processor that converts information into a waveform for analog signal transmission (e.g., via modulation) and / or converts the waveform of a received signal into information (e.g., via demodulation). The one or more modems 326 may process information or waveforms in connection with signal transmission or reception. For example, the one or more modems 326 may include a coder, a decoder, a multiplexer, a demultiplexer, a transmit MIMO processor, a transmit processor, a receive processor, a receive MIMO detector, an automatic gain control component, or the like.

[0071] The one or more APs 328 may perform processing relating to an operating system and / or a higher layer application of the UE 304. For example, the one or more APs 328 may provide a higher-level operating system (HLOS), software, audio or videoDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO19 / 62processing, graphics processing, or the like. In some examples, the one or more APs 328 may be a data source (e.g., for transmissions) or a data sink (e.g., for receptions).

[0072] The one or more transceivers 324 may perform processing related to implementing physical layer (e.g., radio, air interface) communication with other devices such as other UEs 304 or second network entity 302. The one or more transceivers 324 may include one or more RF components, such as an RF transceiver, a front-end module (e.g., an RFFE), or the like. For example, the one or more transceivers 324 may include a transmit path (also referred to as a transmit chain), a receive path (also referred to as a receive chain), and / or an interface with one or more antennas 322.

[0073] The one or more antennas 322 may perform wireless transmission and reception of signals. The one or more antennas 322 may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or one or more antenna elements coupled with one or more transmission or reception components, such as one or more components of FIG. 3.

[0074] For an example downlink transmission by second network entity 302, the processing system 306 (e.g., a transmit processor) may receive data and / or control information. The control information may be for the physical broadcast channel (PBCH), physical control format indicator channel (PCFICH), physical hybrid automatic repeat request (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.

[0075] The processing system 306 (e.g., a transmit processor) may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. The processing system 306 may also generate reference symbols, such as for the primary synchronization signal (PSS), secondary synchronization signal (SSS), PBCH demodulation reference signal (DMRS), or channel state information reference signal (CSI-RS).Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO20 / 62

[0076] The processing system 306 (e.g., a TX MIMO processor) 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 one or more modulators of the processing system 306. The one or more modulators may process one or more respective output symbol streams to obtain an output sample stream. The one or more transceivers 312 may process (e.g., convert to analog, amplify, fdter, and upconvert) the output sample stream to obtain a downlink signal. Second network entity 302 may transmit the downlink signal via the one or more antennas 314.

[0077] In order to receive the downlink transmission at UE 304 (or a sidelink transmission from another UE), the one or more antennas 322 may receive the downlink signal and may provide received signals to the one or more transceivers 324. The one or more transceivers 324 may condition (e.g., fdter, amplify, downconvert, and digitize) the received signals to obtain input samples. The one or more transceivers 324 and / or the processing system 316 may further process the input samples to obtain received symbols.

[0078] The processing system 316 (e.g., modem 326, an RX MIMO detector) may obtain the received symbols, perform MIMO detection on the received symbols if applicable, and provide detected symbols. The processing system 316 (e.g., a modem 326, a receive processor) may process (e.g., de-interleave and decode) the detected symbols. The processing system 316 may provide decoded data for the UE 304 (e.g., to an AP 328) and / or decoded control information (e.g., to a controller / processor of the processing system 316).

[0079] For an example uplink transmission or a sidelink transmission from UE 304, the processing system 316 (e.g., modem 326, a transmit processor) may receive and process data and / or control information to obtain a set of symbols for transmission. The data may be for the physical uplink shared channel (PUSCH), and may be received from a data source such as the AP 328. The control information may be for the physical uplink control channel (PUCCH), and may be received, for example, from a controller / processor of the processing system 316. The processing system 316 (e.g., a modem 326, the transmit processor) may also generate reference symbols for a reference signal (e.g., for a sounding reference signal (SRS), a demodulation reference signal, a phase tracking reference signal, or the like). In some examples, the symbols and / or reference signals may be precoded by the processing system 316 (e.g., modem 326, a TX MIMO processor), furtherDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO21 / 62processed by the one or more transceivers 324 (e.g., for SC-FDM), and transmitted to second network entity 302.

[0080] At second network entity 302, the uplink signals from UE 304 may be received by the one or more antennas 314, conditioned by the one or more transceivers 312 (e.g., filtered, amplified, downconverted, and digitized), detected (e.g., by the processing system 306b such as a modem and / or an RX MIMO detector), and further processed by the processing system 306b (e.g., a modem and / or a receive processor) to obtain decoded data and control information sent by UE 304. The processing system 306b may provide the decoded data and the decoded control information (such as to a controller / processor of the processing system 306b, an AP, first network entity 300, or another entity).

[0081] In various aspects, a wireless communication device, such as first network entity 300, second network entity 302, BS 102, UE 104, or UE 304 may be described as sending, transmitting, obtaining, or receiving various types of data associated with the methods described herein. In these contexts, “transmitting” or “sending” may refer to various mechanisms of outputting data, such as outputting data from a processing system, one or more memories, one or more transceivers, one or more antennas, and / or other aspects described herein. For example, “sending” or “transmitting” by a device may include sending (such as wirelessly, via a wired connection, or both) to a recipient directly or via another device. As another example, “sending” or “transmitting” may include sending internally to a device (such as the UE 304, first network entity 300, or second network entity 302) by a process to memory. “Receiving” or “obtaining” may refer to various mechanisms of obtaining data, such as obtaining data from the processing system, one or more memories, one or more transceivers, one or more antennas, and / or other aspects described herein. For example, “receiving” or “obtaining” by a device may include obtaining (such as wirelessly, via a wired connection, or both) from a recipient directly or via another device. As another example, “receiving” or “obtaining” may include obtaining internally to a device (such as the UE 304, first network entity 300, or second network entity 302) by a process from memory. As used herein, “communicating” by a device may include sending, obtaining, receiving, and / or transmitting a communication. “Communicating” can refer to communication with another device or internal communication of the device.

[0082] In various aspects, the processing system 306 or the processing system 316 may include one or more Al processors (such as Al processor 330 of the processingDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO22 / 62system 316). An Al processor may perform Al processing. The Al processor may include Al accelerator hardware or circuitry such as one or more neural processing units (NPUs), one or more neural network processors, one or more tensor processors, one or more deep learning processors, etc. As an example, the Al processor may perform Al-based beam management, Al-based channel state feedback (CSF), Al-based antenna tuning, and / or Al-based positioning (e.g., non-line of sight positioning prediction). In some cases, at the UE 104, the Al processor may process feedback generated by the UE 304 (e.g., CSF) using hardware accelerated Al inferences and / or Al training. In some cases, at the second network entity 302, the Al processor may decode compressed CSF from the UE 304, for example, using a hardware accelerated Al inference associated with the CSF. In certain cases, the Al processor may perform certain RAN-based functions including, for example, network planning, network performance management, energy-efficient network operations, etc.

[0083] 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.

[0084] FIG. 4A is a diagram 400 illustrating an example of a first subframe within a 5G (e.g., 5G NR) 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.

[0085] 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. One or more subcarriers 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.

[0086] In some examples, a wireless communications frame structure may be implemented using frequency division duplexing (FDD). In FDD, some subcarriers may be configured for DL communication, and other subcarriers (which may overlap in time with the DL subcarriers) may be configured for UL communication. In some other examples, wireless communications frame structures may be implemented using timeDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO23 / 62division duplexing (TDD). In TDD, for a particular set of subcarriers, some subframes are configured for DL communication and other subframes are configured for UL communication.

[0087] In FIGs. 4A and 4C, the wireless communications frame structure is implemented using TDD. “D” indicates DL time resources, “U” indicates UL time resources, and “X” indicates flexible time resources for use or later reconfiguration for either DL or UL communication. 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 12 or 14 symbols, depending on the cyclic prefix (CP) type (e.g., 12 symbols per slot for an extended CP or 14 symbols per slot for a normal CP). 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.

[0088] In certain aspects, the number of slots within a subframe (e.g., a slot duration in a subframe) is based on a numerology. A numerology may define a frequency domain subcarrier spacing and symbol duration, and may be configured for a given bandwidth part, carrier, cell, or network entity. In certain aspects, given a numerology p, there are 2gslots per subframe. Thus, numerologies (p) 0 to 6 may allow for 1, 2, 4, 8, 16, 32, and 64 slots, respectively, per subframe. In some cases, an extended CP (e.g., 12 symbols per slot) may be used with a specific numerology, such as numerology p = 2 allowing for 4 slots per subframe. The subcarrier spacing and symbol length / duration are a function of the numerology. The subcarrier spacing may be equal to 211x 15 kHz. As an example, the numerology p=0 corresponds to a subcarrier spacing of 15 kHz, and the numerology p=6 corresponds to 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 a slot format having 14 symbols per slot (e.g., a normal CP) and a numerology p=2 with 4 slots per subframe. In such a case, the slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 ps.

[0089] 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 referredDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO24 / 62to as a physical RB (PRB)) that extends across, for example, 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). An RE may include a single subcarrier in the frequency domain and a single symbol in the time domain. The number of bits carried by each RE depends on the modulation scheme including, for example, quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM).

[0090] As illustrated in FIG. 4A, some of the REs carry reference (pilot) signals (shown as “RS”) for a UE (e.g., UE 104 of FIGS. 1 and 3). The RS may include a demodulation RS (DMRS) and / or a channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may additionally or alternatively include abeam measurement RS (BRS), a beam refinement RS (BRRS), and / or a phase tracking RS (PT-RS).

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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 (SSB), and in some cases, referred to as a synchronization signal block (SSB). 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.Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO25 / 62

[0095] 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 of a 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.

[0096] 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.Aspects Related to Adaptive Configuration for a Periodic or Semi-persistent Signal

[0097] FIG. 5 depicts an example 500 associated with an adaptation scheme that enables reconfiguration of a BWP via DCI.

[0098] In the example, various communications of DCI are used for adaptive configuration of a BWP via DCI. In particular, in the example 500, a UE may be capable of operating in a state SO or a state SI with respect to communication on a BWP. As shown, the state SO corresponds to a “low power” state and is associated with a first set of configuration parameters (e.g., a maximum bandwidth BWo, a maximum rank Ro, a minimum processing timeline To, and a maximum SS periodicity SSpo). The state SI corresponds to a “high power” state and is associated with a second set of configuration parameters (e.g., a maximum bandwidth BWi, a maximum rank Ri, a minimum processing timeline Ti, and a maximum SS periodicity SSpi).

[0099] As shown, in slot 0, the UE is operating in the state SO (i.e., according to the set of configuration parameters associated with the state SO) and receives DCI 502. The DCI 502 indicates that the UE is to operate in the state SO and schedules a PDSCHDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO26 / 62communication 504 in slot 0 (i.e., in a same slot in which the DCI 502 is received). The UE continues operation in the state SO and receives the PDSCH 504 according to the set of configuration parameters associated with the state SO.

[0100] As further shown, in slot 1, the UE is operating in the state SO and receives DCI 506. The DCI 506 indicates that the UE is to operate in the state SI and schedules a PDSCH communication 508 in slot 2 (i.e., a next slot). After receiving the DCI 506, the UE switches to operation in the state SI (i.e., according to the set of configuration parameters associated with the state SI) such that the UE is operating in the state SI in slot 2. The UE receives the PDSCH communication 508 in slot 2 while operating according to the set of configuration parameters associated with the state SI.

[0101] As shown, in slot 3, the UE is operating in the state SI and receives DCI 510. The DCI 510 indicates that the UE is to operate in the state SI and schedules a PDSCH communication 512 in slot 3 (i.e., in a same slot in which the DCI 510 is received). The UE continues operation in the state SI and receives the PDSCH 512 according to the set of configuration parameters associated with the state SI.

[0102] As further shown, in slot 4, the UE is operating in the state SI and receives DCI 514. The DCI 514 indicates that the UE is to operate in the state SO and schedules a PDSCH communication 516 in slot 5 (i.e., a next slot). After receiving the DCI 514, the UE switches to operation in the state SO such that the UE is operating in the state SO in slot 5. The UE receives the PDSCH communication 516 in slot 5 while operating according to the set of configuration parameters associated with the state SO.

[0103] In some aspects, the adaptation scheme illustrated in the example 500 can be used to provide UE power savings by, for example, enabling the UE to operate in an active B WP at a low power state when possible. However, as noted above, this adaptation scheme is not readily compatible with adaptive configuration for a periodic or semi-persistent signal.Example Signaling of Adaptive Configuration for a Periodic orSemi-persistent Signal

[0104] FIG. 6 depicts a process flow 600 for communications in a network between a network entity 602 and a UE 604. In some aspects, the network entity 602 may be an example of the BS 102 depicted and described with respect to FIG. 1, the first network entity 300 or the second network entity 302 depicted and described with respect to FIG.Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO27 / 623, or a disaggregated base station depicted and described with respect to FIG.2. Similarly, the UE 604 may be an example of UE 104 depicted and described with respect to FIG. 1 or the UE 304 depicted and described with respect to FIG. 3. However, in other aspects, UE 604 may be another type of wireless communications device and network entity 602 may be another type of network entity or network node, such as those described herein. Note that any operations or signaling illustrated with dashed lines may indicate that that operation or signaling is an optional or alternative example.

[0105] At 606, the UE 604 may identify an adaptation configuration associated with a communication of a periodic or semi-persistent signal. As used herein, an adaptation configuration is a configuration that indicates a limitation or boundary for each configuration parameter in a set of configuration parameters in association with communication (e.g., transmission or reception) of a periodic or semi-persistent signal. For example, the adaptation configuration may indicate a maximum bandwidth associated with transmitting or receiving the periodic or semi-persistent signal. As another example, the adaptation configuration may indicate a maximum rank associated with transmitting or receiving the periodic or semi-persistent signal. As another example, the adaptation configuration may indicate a minimum processing timeline associated with transmitting or receiving the periodic or semi-persistent signal. As another example, the adaptation configuration may indicate a maximum SS periodicity associated with transmitting or receiving the periodic or semi-persistent signal. In general, the adaptation configuration may include values indicating a limitation or boundary for each configuration parameter in the set of configuration parameters associated with transmission or reception of a periodic or semi-persistent signal.

[0106] In some aspects, the UE 604 may identify the adaptation configuration based at least in part on an adaptation configuration index. An adaptation configuration index is a value that indicates an adaptation configuration. In some aspects, the UE 604 may be configured with a plurality of adaptation configurations, where each adaptation configuration is associated with a respective adaptation configuration index (e.g., a respective index value). In some aspects, the UE 604 may receive a periodic or semi-persistent signal configuration (e.g., a configuration for the periodic or semi-persistent signal) that includes an adaptation configuration index for communication of the periodic or semi-persistent signal. Upon receiving the adaptation configuration index in the periodic or semi-persistent signal configuration, the UE 604 may identify the adaptationDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO28 / 62configuration to be used for the periodic or semi-persistent signal based at least in part on the adaptation configuration index and the plurality of adaptation configuration indices configured on the UE 604. In this way, the adaptation configuration can be signaled (e.g., using an adaptation configuration index) in the periodic or semi-persistent signal configuration. Similarly, in some aspects, the UE 604 may receive an activation command associated with the periodic or semi-persistent signal, where the activation command includes an adaptation configuration index for communication of the periodic or semi-persistent signal. Upon receiving the adaptation configuration index in the activation command, the UE 604 may identify the adaptation configuration to be used for the (activated) periodic or semi-persistent signal based at least in part on the adaptation configuration index and the plurality of adaptation configuration indices configured on the UE 604. In this way, the adaptation configuration can be signaled (e.g., using an adaptation configuration index) in the activation communication and associated with the periodic or semi-persistent signal.

[0107] In some aspects, the UE 604 may identify the adaptation configuration based at least in part on the periodic or semi-persistent signal configuration. For example, in some aspects, the UE 604 may receive the configuration for the periodic or semi-persistent signal, and the configuration may include the adaptation configuration (e.g., rather than an adaptation configuration index). That is, in some aspects, the adaptation configuration itself may be included in the periodic or semi-persistent signal configuration.

[0108] In some aspects, the UE 604 may identify the adaptation configuration based at least in part on an activation command. For example, in some aspects, the UE 604 may receive an activation command associated with activating the periodic or semi-persistent signal, and the activation command may include the adaptation configuration (e.g., rather than an adaptation configuration index). That is, in some aspects, the adaptation configuration itself may be included in the activation command for the periodic or semi-persistent signal.

[0109] In some aspects, the UE 604 may identify the adaptation configuration as a group adaptation configuration. For example, in some aspects, a group of (or all) periodic or semi-persistent signals may have a single configuration indicating their adaptation configuration. Therefore, in some aspects, the UE 604 may receive an indication of a group adaptation configuration associated with a plurality of periodic or semi-persistentDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO29 / 62signals. In some such aspects, the UE 604 may determine whether the periodic or semi-persistent signal to be communicated by the UE 604 is included in the plurality of periodic or semi-persistent signals for which the group adaptation configuration is configured. If the periodic or semi-persistent signal is included in the plurality of periodic or semi-persistent signals, then the UE 604 may identify the adaptation configuration as the group adaptation configuration.

[0110] In some aspects, the UE 604 may identify the adaptation configuration based at least in part on one or more parameters of the periodic or semi -persistent signal. For example, in some aspects, the adaptation configuration may be a function of or otherwise depend on one or more parameters (e.g., values of one or more parameters) of the periodic or semi-persistent signal. Thus, in some aspects, the UE 604 may identify the adaptation configuration based at least in part on one or more parameters of the periodic or semi-persistent signal as indicated in the periodic or semi-persistent signal configuration. As an example, the UE 604 may be configured with a first adaptation configuration that has a first maximum bandwidth parameter value and a second adaptation configuration that has a second maximum bandwidth value that is larger than the first maximum bandwidth value. In some examples, if the bandwidth of the periodic or semi-persistent signal (e.g., a bandwidth of a CSI-RS) is larger than the first maximum bandwidth value, then the UE 604 may identify the second adaptation configuration as the adaptation configuration for communication of the periodic or semi-persistent signal.

[0111] Similarly, in some aspects, the UE 604 may identify the adaptation configuration based at least in part on one or more parameters of the activation command associated with the periodic or semi-persistent signal. For example, in some aspects, the adaptation configuration may be a function of or otherwise depend on one or more parameters (e.g., values of one or more parameters) of the activation command for the periodic or semi-persistent signal. Thus, in some aspects, the UE 604 may identify the adaptation configuration based at least in part on one or more parameters of the activation command for the periodic or semi-persistent signal.

[0112] In some aspects, the UE 604 may identify the adaptation configuration as an adaptation configuration that was active in association with a communication of a signal prior to the communication of the periodic or semi-persistent signal. That is, in some aspects, the adaptation configuration for the periodic or semi-persistent signal may follows an active configuration associated with communication of another signal.Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO30 / 62

[0113] For example, and with reference to FIG. 7, the UE 604 may be configured with an adaptation configuration corresponding to a state SO (e.g., a set of configuration parameters that define the state SO) and an adaptation configuration corresponding to a state SI (e.g., a set of configuration parameters that define the state SI). In example 700, in slot 0, the UE 604 is operating in the state SO (i.e., according to the set of configuration parameters associated with the state SO) and receives DCI 702. The DCI 702 indicates that the UE 604 is to operate in the state SO and schedules a PDSCH communication 704 in slot 0 (i.e., in a same slot in which the DCI 702 is received). The UE 604 continues operation in the state SO and receives the PDSCH communication 704 according to the set of configuration parameters associated with the state SO. As further shown, the UE 604 continues operation in the state SO in slot 2. In this example, the UE 604 is to receive a downlink SPS PDSCH communication 706 in slot 2. Here, the UE 604 identifies the adaptation configuration for the downlink SPS PDSCH communication 706 as the adaptation configuration corresponding to state SO (i.e., the adaptation configuration that was active in association with a communication of the PDSCH communication 704 prior to the communication of the downlink SPS PDSCH communication 706).

[0114] In another example 750, in slot 0, the UE 604 is operating in the state SO (i.e., according to the set of configuration parameters associated with the state SO) and receives DCI 752. The DCI 752 indicates that the UE 604 is to operate in the state SI and schedules a PDSCH communication 754 in slot 1 (i.e., a next slot). As shown, the UE 604 switches operation to the state SI and receives the PDSCH communication 754 according to the set of configuration parameters associated with the state SI. As further shown, the UE 604 continues operation in the state SI in slot 2. In this example, the UE 604 is to receive a downlink SPS PDSCH communication 756 in slot 2. Here, the UE 604 identifies the adaptation configuration for the downlink SPS PDSCH communication 756 as the adaptation configuration corresponding to state SI (i.e., the adaptation configuration that was active in association with the PDSCH communication 754 prior to the communication of the downlink SPS PDSCH communication 756). In this way, the UE 604 may, in some aspects, select an adaptation configuration for a periodic or semi-persistent signal based at least in part on identifying a configuration that is active for another signal or communication.

[0115] At 608, the UE 604 may operate according to the set of configuration parameters indicated in the adaptation configuration. That is, the UE 604 may commenceDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO31 / 62operation according to the set of configuration parameters indicated in the adaptation configuration (e.g., such that the UE 604 operates in a state as defined by the set of configuration parameters of the adaptation configuration.

[0116] At 610, the UE 604 may perform the communication during operation according to the set of configuration parameters indicated in the adaptation configuration. That is, the UE 604 may transmit or receive the periodic or semi-persistent signal according to the set of configuration parameters.

[0117] A behavior of the UE 604 after communication of the periodic or semi-persistent signal according to the set of configuration parameters indicated in the adaptation configuration should be configured on the UE 604.

[0118] In some aspects, the UE 604 may return to a prior adaptation configuration after communication of the periodic or semi-persistent signal. For example, in some aspects, after the communication of the periodic or semi-persistent signal, the UE 604 may identify an adaptation configuration that was active prior to the communication of the periodic or semi-persistent signal, and may operate according to a set of configuration parameters associated with in the adaptation configuration that was active prior to the communication of the periodic or semi-persistent signal. For example, with reference to example 800 in FIG. 8, in slot 0, the UE 604 is operating in the state SO (i.e., according to the set of configuration parameters associated with the state SO) and receives DCI 802. The DCI 802 indicates that the UE 604 is to operate in the state SO and schedules a PDSCH communication 804 in slot 0 (i.e., in a same slot in which the DCI 802 is received). The UE 604 continues operation in the state SO and receives the PDSCH communication 804 according to the set of configuration parameters associated with the state SO. In this example, the UE 604 is to receive a downlink SPS PDSCH communication 806 in slot 2. The UE 604 identifies (e.g., based at least in part on an adaptation configuration index signaled in the periodic or semi-persistent signal configuration) the adaptation configuration for the downlink SPS PDSCH communication 806 as the adaptation configuration corresponding to state SI. Therefore, the UE 604 transitions to operation in the state SI such that, at slot 2, the UE 604 is operating in the state SI and receives the downlink SPS communication 806. In this example, the UE 604 is configured to return to a prior adaptation configuration after communication of the periodic or semi-persistent signal. Therefore, after the UE 604 receives the downlink SPS communication 806, the UE 604 returns to the adaptationDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO32 / 62configuration that was active prior to reception of the downlink SPS communication 806 - the adaptation configuration corresponding to state SO, and resumes operation in the state SO.

[0119] Additionally or alternatively, the UE 604 may remain in the same adaptation configuration after communication of the periodic or semi-persistent signal. For example, in some aspects, after the communication of the periodic or semi-persistent signal, the UE 604 may (continue) operating according to the set of configuration parameters associated with the adaptation configuration. For example, with reference to example 820 in FIG. 8, in slot 0, the UE 604 is operating in the state SO (i.e., according to the set of configuration parameters associated with the state SO) and receives DCI 822. The DCI 822 indicates that the UE 604 is to operate in the state SO and schedules a PDSCH communication 824 in slot 0 (i.e., in a same slot in which the DCI 822 is received). The UE 604 continues operation in the state SO and receives the PDSCH communication 824 according to the set of configuration parameters associated with the state SO. In this example, the UE 604 is to receive a downlink SPS PDSCH communication 826 in slot 2. The UE 604 identifies (e.g., based at least in part on an adaptation configuration index signaled in the periodic or semi-persistent signal configuration) the adaptation configuration for the downlink SPS PDSCH communication 826 as the adaptation configuration corresponding to state SI. Therefore, the UE 604 transitions to operation in the state SI such that, at slot 2, the UE 604 is operating in the state SI and receives the downlink SPS communication 826. In this example, the UE 604 is configured to remain in the same adaptation configuration after communication of the periodic or semi-persistent signal. Therefore, after the UE 604 receives the downlink SPS communication 826, the UE 604 remains in the same adaptation configuration that was active during reception of the downlink SPS communication 826 - the adaptation configuration corresponding to state SI.

[0120] Additionally or alternatively, the UE 604 may identify another adaptation configuration to be used after the communication of the periodic or semi-persistent signal, and may operate according to the set of configuration parameters associated with the other adaptation configuration after the communication of the periodic or semi-persistent signal. For example, with reference to example 840 in FIG. 8, in slot 0, the UE 604 is operating in the state SO (i.e., according to the set of configuration parameters associated with the state SO) and receives DCI 842. The DCI 842 indicates that the UE 604 is to operate in the state SO and schedules a PDSCH communication 844 in slot 0 (i.e., in aDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO33 / 62same slot in which the DCI 842 is received). The UE 604 continues operation in the state SO and receives the PDSCH communication 844 according to the set of configuration parameters associated with the state SO. In this example, the UE 604 is to receive a downlink SPS PDSCH communication 846 in slot 2. The UE 604 identifies (e.g., based at least in part on an adaptation configuration index signaled in the periodic or semi-persistent signal configuration) the adaptation configuration for the downlink SPS PDSCH communication 846 as the adaptation configuration corresponding to state SI. Therefore, the UE 604 transitions to operation in the state SI such that, at slot 2, the UE 604 is operating in the state SI and receives the downlink SPS communication 846. In this example, the UE 604 is configured to identify another adaptation configuration to be used after the communication of the periodic or semi-persistent signal. In some aspects, the other adaptation configuration may be specified (e.g., in an applicable wireless communications standard) or configured (e.g., by the network entity 602). In the example 840, the UE 604 identifies (e.g., based on a configuration of the UE 604) the other adaptation configuration as an adaptation configuration corresponding to a state Sx. Therefore, after the UE 604 receives the downlink SPS communication 846, the UE 604 transitions to operating in the adaptation configuration corresponding to the state Sx (e.g., according to the set of configuration parameters indicated in the adaptation configuration corresponding to the state Sx).

[0121] In some aspects, the UE 604 may be configured to not expect communications of signals during at least a portion of a slot prior to a slot associated with communication of the periodic or semi-persistent signal. That is, in some aspects, if the UE 604 is to transition to operating according to another set of configuration parameters associated with another adaptation configuration before (or after) communication of a periodic or semi-persistent signal, then the UE 604 may be configured such that the UE 604 is not expected to transmit or receive signals during at least a portion of a slot including a switching timeline associated with such a transition. In some aspects, the switching timeline may be the same as that used for the DCI-based adaptation scheme described herein.

[0122] In some aspects, the UE 604 may be configured to not expect to receive control information (e.g., DCI or other types of control information) during any slots or symbols of a switching timeline (e.g., during any portion of the switching timeline) associated withDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO34 / 62operating according to a set of configuration parameters associated with the adaptation configuration.

[0123] Alternatively, in some aspects, the UE 604 may be configured to expect to receive control information during a slot of the switching timeline, with the control information being received according to the adaptation configuration for the slot (e.g., the adaptation configuration that is active prior to the switching timeline). That is, in some aspects, the UE 604 may receive control information during a portion of a slot included in a switching timeline associated with operating according to the set of configuration parameters associated with the adaptation configuration, and the control information may be received according to a set of configuration parameters associated with an adaptation configuration that was active prior to the switching timeline. In an example 900, with reference to FIG. 9, in slot 0, the UE 604 is operating in the state SO (i.e., according to the set of configuration parameters associated with an adaptation configuration corresponding to the state SO) and receives DCI 902. The DCI 902 indicates that the UE 604 is to operate in the state SO and schedules a PDSCH communication 904 in slot 0 (i.e., in a same slot in which the DCI 902 is received). The UE 604 continues operation in the state SO and receives the PDSCH communication 904 according to the set of configuration parameters associated with the state SO. In this example, the UE 604 is to receive a downlink SPS PDSCH communication 906 in slot 2. The UE 604 identifies (e.g., based at least in part on an adaptation configuration index signaled in the periodic or semi-persistent signal configuration) the adaptation configuration for the downlink SPS PDSCH communication 906 as the adaptation configuration corresponding to state SI. Therefore, the UE 604 is to transition to operation in the state SI such that, at slot 2, the UE 604 is operating in the state SI and can receive the downlink SPS communication 906. In this example, the UE 604 is configured to expect to receive control information during a slot of the switching timeline, and is to receive the control information according to the adaptation configuration that is active prior to the switching timeline. Therefore, in the example 900, the UE 604 may receive the DCI 908 in slot 1 according to the adaptation configuration that was active during the slot prior to the switching timeline -the adaptation configuration corresponding to the state SO. Thus, in this example, the UE 604 receives the DCI 908 during operation in the state SO (e.g., according to the set of configuration parameters associated with the adaptation configuration corresponding to the state SO). As shown, after receiving the DCI 908, the UE 604 transitions to the stateDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO35 / 62SI and receives the downlink SPS communication 906 in slot 2 while operating according to the state SI.

[0124] Alternatively, in some aspects, the UE 604 may be configured to expect to receive control information based on the adaptation configuration for the periodic or semi-persistent signal in the following slot. That is, in some aspects, the UE 604 may receive control information during a portion of a slot included in a switching timeline associated with operating according to the set of configuration parameters associated with the periodic or semi-persistent signal, and the control information may be received according to the set of configuration parameters associated with the periodic or semi-persistent signal (e.g., the adaptation configuration for the following slot).

[0125] Alternatively, in some aspects, the UE 604 may be configured to expect to receive control information only in occasions (e.g., resources) common to both the adaptation configuration associated with the periodic or semi-persistent signal and the adaptation configuration that was active prior to the switching timeline associated with switching to the adaptation configuration for the periodic or semi-persistent signal. That is, in some aspects, the UE 604 may receive control information in one or more resources associated with both the adaptation configuration associated with the periodic or semi-persistent signal and another adaptation configuration that was active prior to the switching timeline associated with operating according to the set of configuration parameters associated with the adaptation configuration for the periodic or semi-persistent signal.

[0126] In some aspects in which the UE 604 may expect to receive control information, the UE 604 may be configured not to expect to receive or transmit any signals (e.g., including control information) for a portion of a slot preceding a slot in which the periodic or semi-persistent signal is to be communicated.

[0127] Note that the process flows and examples illustrated in FIGS. 6-9 are examples of adaptive configuration for a periodic or semi-persistent signal, and aspects of the present disclosure may be applied to adaptive configuration for a periodic or semi-persistent signal. Note that the process flows and examples illustrated in FIGS. 6-9 are described herein to facilitate an understanding of adaptive configuration for a periodic or semi-persistent signal, and aspects of the present disclosure may be performed in various manners via alternative or additional signaling and / or operations. In certain aspects, theDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO36 / 62operations and / or signaling of FIGS. 6-9 may occur in an order different from that described or depicted, and various actions, operations, and / or signaling may be added, omitted, or combined.

[0128] FIG. 10 depicts a process flow 1000 for communications in a network between a network entity 602 and a UE 604. In some aspects, the network entity 602 may be an example of the BS 102 depicted and described with respect to FIG. 1, the first network entity 300 or the second network entity 302 depicted and described with respect to FIG. 3, or a disaggregated base station depicted and described with respect to FIG. 2.Similarly, the UE 604 may be an example of UE 104 depicted and described with respect to FIG. 1 or the UE 304 depicted and described with respect to FIG.3. However, in other aspects, UE 604 may be another type of wireless communications device and network entity 602 may be another type of network entity or network node, such as those described herein. Note that any operations or signaling illustrated with dashed lines may indicate that that operation or signaling is an optional or alternative example.

[0129] At 1006, the UE 604 may identify a first adaptation configuration associated with a communication of a periodic or semi-persistent signal. In some aspects, the first adaptation configuration may indicate a first set of configuration parameters associated with the communication of the periodic or semi-persistent signal. In some aspects, the UE 604 may identify (e.g., receive, select, or otherwise determine) the first adaptation configuration in a manner similar to those described above with respect to reference 606 of FIG. 6.

[0130] At 1008, the UE 604 may receive an override indication indicating that the UE 604 is to operate according to a second adaptation configuration rather than the first adaptation configuration. In some aspects, the second adaptation configuration may indicate a second set of configuration parameters (e.g., a different set of configuration parameters based on which to communicate the periodic or semi-persistent signal). In this way, the override indication enables the network entity 602 to override an adaptation configuration switch by transmitting an indication to the UE 604.

[0131] In some aspects, the override indication is in DCI. For example, the DCI may include a field value or a combination of field values indicating to the UE 604 refrain from switching to the first adaptation configuration for the periodic or semi-persistent signal. As another example, the techniques and apparatuses for adaptive configuration viaDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO37 / 62DCI can be used to indicate the second adaptation configuration to the UE 604, and the indication of the second adaptation configuration may serve as the override indication.

[0132] In some aspects, the DCI may include scheduling information that schedules a second communication during a switching timeline associated with operating according to the first set of configuration parameters. In some such aspects, the scheduling information may serve as the override indication. That is, the DCI may schedule a reception or transmission that conflicts with the switching timeline associated with transitioning to operation according to the set of configuration parameters associated with the first adaptation configuration, and the conflicting scheduling information may serve as indication to the UE 604 that the UE 604 should operate according to a configuration associated with the communication (e.g., a second adaptation configuration) rather than the configuration associated with the periodic or semi-persistent signal (e.g., the first adaptation configuration).

[0133] In some aspects, after receiving the override indication, the UE 604 may refrain from performing the communication of the periodic or semi-persistent signal based at least in part on the override indication. That is, in some aspects, if the UE 604 receives an override indication associated with an adaptation configuration for communication of a periodic or semi-persistent signal periodic signal, then the UE 604 may refrain from performing reception or transmission of the periodic or semi-persistent signal.

[0134] Alternatively, after receiving the override indication, the UE 604 may in some aspects perform the communication of the periodic or semi-persistent signal during operation according to the second set of configuration parameters. That is, in some aspects, if the UE 604 receives an override indication associated with an adaptation configuration for communication of a periodic or semi-persistent signal periodic signal, then the UE 604 may perform reception or transmission of the periodic or semi-persistent signal according to the second (newly indicated) adaptation configuration.

[0135] Alternatively, after receiving the override indication, the UE 604 may in some aspects perform a partial communication of the periodic or semi-persistent signal during operation according to the second set of configuration parameters. That is, in some aspects, if the UE 604 receives an override indication associated with an adaptation configuration for communication of a periodic or semi-persistent signal periodic signal,Dinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO38 / 62then the UE 604 may perform partial reception of the periodic or semi-persistent signal (e.g., such that the UE 604 receives CSI-RS in only a portion of a CSI-RS bandwidth).

[0136] At 1010, the UE 604 may operate according to the second set of configuration parameters based at least in part on the override indication. That is, the UE 604 may commence operation according to the second set of configuration parameters indicated in the second adaptation configuration (e.g., rather than the first set of configuration parameters indicated in the first adaptation configuration) such that the UE 604 operates in a state as defined by the second set of configuration parameters of the second adaptation configuration. In some aspects, the UE 604 may then perform a communication during operation according to the second set of configuration parameters (e.g., the UE 604 may transmit or receive a periodic or semi-persistent signal according to the second set of configuration parameters).

[0137] FIG. 11 illustrates various examples of the override indication depicted and described with respect to FIG. 10. With respect to the examples in FIG. 11, the UE 604 is configured with an adaptation configuration corresponding to a state SO (e.g., a set of configuration parameters that define the state SO) and an adaptation configuration corresponding to a state SI (e.g., a set of configuration parameters that define the state SI). Further, as shown in FIG. 11, the UE 604 is operating in the state SO (i.e., according to the set of configuration parameters associated with the state SO) in slot 0 and receives DCI 1102 / 1122 / 1142 / 1162. The DCI 1102 / 1122 / 1142 / 1162 indicates that the UE 604 is to operate in the state SO and schedules a PDSCH communication 1104 / 1124 / 1144 / 1164 in slot 0. The UE 604 continues operation in the state SO and receives the PDSCH communication 1104 / 1124 / 1144 / 1164 according to the set of configuration parameters associated with the state SO. Furthermore, in the examples in FIG. 11, the UE 604 is to receive a downlink SPS PDSCH communication 1106 / 1126 / 1146 / 1166 in slot 2, and has identified the adaptation configuration for reception of the downlink SPS PDSCH communication 1106 / 1126 / 1146 / 1166 as the adaptation configuration corresponding to state SI. Prior to the override indications described with respect to the examples below (and indicated by black boxes in FIG. 11), the UE 604 is to transition back to operation in the state SO after reception of the downlink SPS PDSCH communication 1106 / 1126 / 1146 / 1166.

In the example 1100, the UE 604 continues operating according to the adaptation configuration corresponding to the state SO after receiving the downlink SPS PDSCH communication in slot 2 while operating according to the adaptation configuration corresponding to state SO.

[0139] In the example 1120, the UE 604 receives an override indication in DCI 1128 in slot 1. Here, the override indication indicates that the UE 604 is to operate in the state 51 in a slot after a next slot (i.e., slot 3), meaning that the UE 604 is to operate according to the adaptation configuration corresponding to the state SI for reception of the downlink SPS PDSCH communication 1126 in slot 2, and is to switch to operation according the adaptation configuration corresponding to the state SO after reception of the downlink SPS PDSCH communication 1126 (e.g., rather than transitioning back to the state SO). In the example 1120, the UE 604 continues operating according to the adaptation configuration corresponding to the state SI after receiving the downlink SPS PDSCH communication 1126 in slot 2 while operating according to the adaptation configuration corresponding to state SI.

[0140] In the example 1140, the UE 604 receives an override indication in DCI 1148 in slot 2. Here, the override indication indicates that the UE 604 is to operate in the state SI in a next slot (i.e., slot 3), meaning that the UE 604 is to continue to operate according to the adaptation configuration corresponding to the state SI after reception of the downlink SPS PDSCH communication 1146 in slot 2 (e.g., rather than transitioning back to the state SO). In the example 1140, the UE 604 continues operating according to the adaptation configuration corresponding to the state SI after receiving the downlink SPS PDSCH communication 1146 in slot 2 while operating according to the adaptation configuration corresponding to state SI.

[0141] In the example 1160, the UE 604 receives an override indication in DCI 1168 in slot 1. Here, the override indication indicates that the UE 604 is to operate in the state SO in a next slot (i.e., slot 2), meaning that the UE 604 is to operate according to the adaptation configuration corresponding to the state SO for reception of the downlink SPS PDSCH communication 1166 in slot 2 (e.g., rather than according to the adaptation configuration corresponding to the state SI). Further, the DCI 1168 schedules a PDSCHDinsmore Ref. QCM2500942WOQualcomm Ref. No. 2500942WO40 / 62communication 1170 in slot 1 (i.e., the slot in which the DCI 1168 is communicated). In the example 1160, the UE 604 continues operating according to the adaptation configuration corresponding to the state SO and receives the PDSCH communication 1170 in slot 1 and the downlink SPS PDSCH communication 1166 in slot 2. As further shown, after receiving the downlink SPS PDSCH communication 1166 in slot 2 while operating according to the adaptation configuration corresponding to state SO, the UE 604 continues operation according the adaptation configuration corresponding to the state SO.
