[0003] The following relates to wireless communications, including hybrid waveform communications. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each of which supports wireless communications for communication devices, which may be referred to as user equipment (UE).

[0047] In wireless communications, various waveforms may be used to communicate with different devices. These various waveforms may be associated with different characteristics, such as spectral efficiency, peak-to-average power ratio (PAPR), link budget, power consumption, other characteristics, or any combination thereof. Communications in various scenarios may take advantage of these different characteristics or tradeoffs between these characteristics. However, some approaches to using different waveforms do not allow for mixing multiple waveforms within the bandwidth of the wireless communication system.

[0048] Therefore, the method described herein relates to using a hybrid waveform for communication. The hybrid waveform can be implemented as a combination of multiple waveforms mixed together in the same total bandwidth. For example, the waveform type may include a waveform based on frequency domain processing and a waveform based on time domain processing using various methods, such as direct sequence, RSMA, sequence repetition (e.g., up-sampled DFT, or distributed DFT-s-FDMA), constant envelope waveform (e.g., MSK in GMSK, BT LE, Zigbee, MSK nonlinear modulation), contiguous DFT-s-FDMA, OFDMA, or FMCW. Different combinations of such waveforms can be multiplexed together on different frequency domain resources within the total bandwidth. In some examples, control signaling can be used to schedule resources for different waveforms (e.g., using waveform-specific different regions, optionally with protection around certain regions, such as those regions for waveforms based on time domain processing). In this way, a wireless communication system can achieve greater flexibility by using multiple or hybrid waveforms to utilize different characteristics of such waveforms in different situations.

[0049] Aspects of the disclosure are first described in the context of wireless communication systems. Aspects of the disclosure are then described in the context of wireless communication systems, processing schemes, and process flows. Aspects of the disclosure are further illustrated by and described with reference to device diagrams, system diagrams, and flow diagrams involving hybrid waveform communications.

[0050] Figure 1 An example of a wireless communication system 100 supporting hybrid waveform communications according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0051] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0052] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile or both stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communication with various types of devices such as Figure 1 Other UEs 115 or network entities 105 are shown communicating.

[0053] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0054] In some examples, the network entities 105 may communicate with the core network 130, or with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, the network entities 105 may communicate with each other via the backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols) directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130). In some examples, the network entities 105 may communicate with each other via the midhaul communication links 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication links 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, the midhaul communication links 162, or the fronthaul communication links 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0055] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a Home Node B, a Home Evolved Node B, or other suitable terminology). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in a clustered (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0056] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0057] The split of functionality between CU 160, DU 165, and RU 170 is flexible and may support different functionality depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between the CU 160 and the DU 165 or between the DU 165 and the RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of the CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of the CU 160, DU 165, or RU 170). The CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and the DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented according to an interface (eg, a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0058] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to the core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as host entities or IAB hosts. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a host network entity 105 (e.g., a host base station 140). One or more host network entities 105 (e.g., IAB hosts) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB host. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0059] For example, an access network (AN) or RAN may include an access node (e.g., an IAB host), communications between an IAB node 104, and one or more UEs 115. The IAB host may facilitate connectivity between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, the IAB host may refer to a RAN node that has a wired or wireless connection to the core network 130. The IAB host may include a CU 160 and at least one DU 165 (e.g., and RU 170), wherein the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB host and the IAB node 104 may communicate via an F1 interface according to a protocol that defines signaling messages (e.g., an F1 AP protocol). Additionally or alternatively, CU 160 may communicate with the core network via an interface (which may be an example of a portion of a backhaul link) and may communicate with other CUs 160 (e.g., CU 160 associated with an alternative IAB host) via an Xn-C interface (which may be an example of a portion of a backhaul link).

[0060] An IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UE 115, wireless self-backhaul capabilities, etc.). DU 165 may act as a distributed scheduling node toward child nodes associated with IAB node 104, and IAB-MT may act as a scheduled node toward a parent node associated with IAB node 104. That is, an IAB host may be referred to as a parent node that communicates with one or more child nodes (e.g., an IAB host may relay for UE transmissions through one or more other IAB nodes 104). Additionally or alternatively, depending on the relay chain or configuration of the AN, an IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104. Thus, the IAB-MT entity of the IAB node 104 may provide a Uu interface for the child IAB node 104 to receive signaling from the parent IAB node 104 , and a DU interface (eg, DU 165 ) may provide a Uu interface for the parent IAB node 104 to signal to the child IAB node 104 or the UE 115 .

[0061] For example, the IAB node 104 may be referred to as a parent node that supports child IAB node communications, and may be referred to as a child IAB node associated with the IAB host. The IAB host may include a CU 160 having a wired or wireless connection (e.g., backhaul communication link 120) to the core network 130, and may act as a parent node of the IAB node 104. For example, the DU 165 of the IAB host may relay transmission to the UE 115 through the IAB node 104, and may directly signal the UE 115 of the transmission. The CU 160 of the IAB host may signal the establishment of a communication link to the IAB node 104 via the F1 interface, and the IAB node 104 may schedule transmission (e.g., transmission relayed from the IAB host to the UE 115) via the DU 165. That is, data may be relayed to and from the IAB node 104 via signaling via the NR Uu interface of the MT to the IAB node 104. Communications with the IAB node 104 may be scheduled by the DU 165 of the IAB host, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .

[0062] Where the techniques described herein are applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support hybrid waveform communications as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the disaggregated RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0063] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0064] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0065] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between these devices and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate" when referring to the network entity 105 may refer to any portion of a network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0066] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified based on a channel raster used for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be made by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0067] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. A carrier may carry either downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink communications and uplink communications (e.g., in TDD mode).

[0068] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths of carriers of a particular radio access technology (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). Devices of the wireless communication system 100 (e.g., the network entity 105, the UE 115, or both) may have a hardware configuration that supports communications using a particular carrier bandwidth, or may be configured to support communications using one of the carrier bandwidths in the set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.

[0069] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing may be inversely related. The amount of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), so that a relatively high amount of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0070] One or more parameter sets for a carrier may be supported, and a parameter set may include a subcarrier spacing ( ) and cyclic prefix. A carrier may be divided into one or more BWPs with the same or different parameter sets. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications of a UE 115 may be constrained to one or more active BWPs.

[0071] The time interval for the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, which may be, for example, a sampling period. seconds, of which may indicate the supported subcarrier spacing, and The supported discrete Fourier transform (DFT) size may be indicated. Time intervals of the communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0072] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended to the front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0073] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the amount of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0074] According to various techniques, physical channels may be multiplexed using carriers for communication. Physical control channels and physical data channels may be multiplexed for signaling via downlink carriers, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of the control channel candidates may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0075] The network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with the network entity 105 (e.g., using a carrier), and may be associated with an identifier used to distinguish adjacent cells (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other cell identifier). In some examples, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) on which the logical communication entity operates. Depending on various factors such as the capabilities of the network entity 105, such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping coverage areas 110, and the like.

[0076] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have service subscriptions with a network provider that supports the macro cell. Small cells may be associated with a lower power network entity 105 (e.g., a lower power base station 140) than macro cells, and small cells may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with small cells (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A network entity 105 may support one or more cells, and may also use one or more component carriers to support communications via one or more cells.

[0077] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0078] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0079] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the network entities 105 may have different frame timing, and in some examples, transmissions from different network entities 105 may not be aligned in time. The techniques described herein may be used for either synchronous operation or asynchronous operation.

[0080] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or acquire information and relay such information to a central server or application that uses the information or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, wildlife monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0081] Some UEs 115 may be configured to employ an operating mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not transmit and receive concurrently). In some examples, half-duplex communication may be performed at a reduced peak rate. Other energy-saving techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communications, operating using limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0082] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). The UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communications may include private communications or group communications and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms "ultra-reliable," "low latency," and "ultra-reliable low latency" are used interchangeably herein.

[0083] In some examples, a UE 115 may be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 in such a group may be outside of the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0084] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these items. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or both.

[0085] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management of UEs 115 served by network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP services 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0086] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide service to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than communications using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0087] The wireless communication system 100 may also operate using a super high frequency (SHF) region (also known as a centimeter band) that may be in the range of 3 GHz to 30 GHz or an extremely high frequency (EHF) region (e.g., 30 GHz to 300 GHz) (also known as a millimeter band) using a spectrum. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between a UE 115 and a network entity 105 (e.g., a base station 140, a RU 170), and the EHF antennas of the corresponding devices may be smaller and closer together than UHF antennas. In some examples, such technology may facilitate the use of antenna arrays within a device. However, the propagation of EHF transmissions may be affected by greater attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be used across transmissions using one or more different frequency regions, and the use of frequency bands specified across these frequency regions may vary by country or regulatory agency.

[0088] The wireless communication system 100 can utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 can employ carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands can be based on carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating using licensed bands. Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0089] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly such as an antenna tower. In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a set of antenna ports of multiple rows and columns that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0090] The network entity 105 or UE 115 may use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. The multiple signals may be sent, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technologies include: single-user MIMO (SU-MIMO), in which multiple spatial layers are sent to the same receiving device; and multi-user MIMO (MU-MIMO), in which multiple spatial layers are sent to multiple devices.

[0091] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other orientation).

[0092] The network entity 105 or the UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the network entity 105 (e.g., the base station 140, the RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the network entity 105 along different directions. For example, the network entity 105 may send signals according to different sets of beamforming weights associated with different transmission directions. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device (such as the network entity 105), or by a receiving device (such as the UE 115)) beam directions for later transmission or reception by the network entity 105.

[0093] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., a direction associated with a receiving device (such as receiving network entity 105 or receiving UE 115)). In some examples, a beam direction associated with transmission along a single beam direction may be determined based on signals transmitted along one or more beam directions. For example, UE 115 may receive one or more of the signals sent by network entity 105 along different directions, and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0094] In some examples, transmission by a device (e.g., by network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more subbands. Network entity 105 may send a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may or may not be precoded. UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

[0095] A receiving device (e.g., UE 115) may perform receiving operations according to multiple receiving configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a receiving device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple receiving directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receiving beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receiving beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0096] The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly to communicate via logical channels. The MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also implement error detection techniques, error correction techniques, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer may provide the establishment, configuration, and maintenance of an RRC connection for a radio bearer supporting user plane data between the UE 115 and the network entity 105 or the core network 130. The PHY layer may map transport channels to physical channels.

[0097] UE 115 and network entity 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data via a communication link (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In some other examples, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0098] In some implementations, the UE 115 and the network entity 105 may support the use of multiple waveforms within a single overall bandwidth for communication in a wireless communication system. For example, various devices within the wireless communication system may use different waveforms, all within the overall bandwidth of the system, for communication. Such waveforms may include waveforms based on the frequency domain, based on the time domain, or based on both the frequency domain and the time domain. The network entity 105, one or more other wireless devices, or any combination thereof may determine or send scheduling parameters to schedule the use of such various waveforms for different devices, and such different devices may communicate using one or more different waveforms, all within the same overall bandwidth of the device, the wireless communication system, or both.

[0099] Figure 2 An example of a wireless communication system 200 supporting hybrid waveform communications according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may involve a network entity 105-a, which may be an example of one or more network entities discussed with respect to other figures. The wireless communication system 200 may involve a UE 115-a, which may be an example of a UE discussed with respect to other figures.

[0100] In wireless communications, a waveform may refer to a signal whose energy is mostly or completely constrained to a frequency bandwidth (e.g., an allocated bandwidth). Many such waveforms have been adopted or studied for various aspects of wireless communications. These waveforms may have varying characteristics or advantages (e.g., spectral efficiency, PAPR, link budget, power consumption, different types of processing (e.g., time domain processing, frequency domain processing, spatial domain processing, or any combination thereof), one or more other features or advantages, or any combination thereof). Some radio technologies (including, for example, future radio technologies) may adopt different tradeoffs in different scenarios. For example, in some scenarios, a first waveform may be used, and in other scenarios, other waveforms may be selected or used. Such selection or use may take into account varying characteristics or advantages (e.g., based on which characteristics or advantages may provide improvements to communications in various scenarios).

[0101] The use of one or more hybrid waveforms (e.g., multiple waveforms mixed together in the same total bandwidth) can be a technique for wireless communication systems (e.g., sixth generation or 6G systems) to provide a unified framework with flexibility for different tradeoffs between conflicting objectives that may exist in wireless communication systems. In some examples, OFDMA can be used as a framework for combining such multiple waveforms in communications. Additionally or alternatively, a joint scheduling method can be used to coordinate the use of multiple waveforms. In addition, methods for processing (e.g., joint physical layer processing at the transmitter, receiver, or both) can be used to process different waveforms. Other designs or methods used in wireless communication systems may also consider the use of multiple waveforms (e.g., physical layer designs, MAC designs, other designs, or any combination thereof), which can be used to provide flexibility to wireless communication systems in different scenarios that may be associated with different characteristics.

[0102] Various techniques using one or more hybrid waveforms may be used to send data in a wireless communication system. It should be understood that these techniques may be applied to the communication of any type of data, including control channel information, information associated with the format of a physical layer packet, channel state information, any information communicated by a UE, a network entity, or other wireless communication device, or any combination thereof.

[0103] An example scenario for using multiple waveforms may be a satellite system. In a satellite system (e.g., a low earth orbit satellite system, optionally involving a cellular phone depending on the factors), the budget for uplink communications may be limited. For example, assuming satellite service, some devices may only provide emergency messaging services. In such cases, a trade-off may be made between spectral efficiency and PAPR. However, other units (e.g., ground units) may have other form factors. For example, a ground relay network entity may have a much larger antenna and power amplifier, and a dish unit may be able to provide a higher data rate. Therefore, PAPR metrics may not be a problem for these devices compared to other devices. Another example in which multiple waveforms may be used is a scenario involving uplink synchronization between users in a very large cell.

[0104] In these and other examples, it may be desirable to accommodate the use of multiple waveforms within a single overall bandwidth of a wireless communication system. In some cases, the use of OFDMA may provide a framework in which frequency regions may be cut out for other waveforms, and such an approach may be applied to uplink communications, downlink communications, or both.

[0105] In some examples, a high frequency wireless communication system may be used. In such a system, the power consumption for transmission may increase with the carrier frequency, but the signal bandwidth may remain the same. Therefore, power saving and low PAPR may be considerations for high frequency systems. In some such cases, there may be a trade-off between PAPR and spectral efficiency (e.g., a higher PAPR may be associated with a lower spectral efficiency, and vice versa). Therefore, it may be desirable to adapt to the use of multiple waveforms within a single total bandwidth of a wireless communication system. In some cases, the use of OFDMA may provide a framework in which frequency regions may be cut out for other waveforms, and may be applied to uplink communications, downlink communications, or both. For example, the OFDMA method may define a grid of time and frequency resources, and assign these resources between different devices, logical channels, other elements, or any combination thereof. This framework is very suitable for the subject matter described herein, because this same convention or method may be applied to assign different resources to different waveforms within the total system bandwidth.

[0106] In order to provide the use of multiple waveforms in a single total bandwidth, various methods, techniques, schemes, processes or procedures may be used. For example, different waveforms may be mixed in the time domain (e.g., a single waveform type may be used for a specific user at any given time). Additionally or alternatively, FDM in waveforms may be used. For example, a total bandwidth (e.g., for a device or wireless communication system) may be divided into regions in which one or more waveforms may be used. The division of regions may be consistent with the division of BWP or may be divided in different ways. For example, the division may be more dynamic than BWP or have a finer resolution than BWP (e.g., multiple waveforms may be mixed in a single BWP). Additionally or alternatively, dynamic scheduling may indicate the type of waveform, its frequency allocation, or both. The scheduling device may consider or analyze the tradeoff between spectral efficiency and link budget or power consumption, and this analysis may provide a basis (e.g., partially or completely) for selecting one or more waveforms. Generally speaking, in some cases, such waveforms can be classified into two categories: waveforms that rely on time domain processing (e.g., where the waveform is generated or received without using a Fast Fourier Transform (FFT) or Inverse Fast Fourier Transform (IFFT) operation) and waveforms that rely on frequency domain processing (e.g., where the waveform is generated or received using an FFT or IFFT operation). In some examples, some waveforms can be processed using time domain processing, frequency domain processing, or both.

[0107] For example, Figure 2 As shown, UE 115-a and network entity 105-a can communicate in a wireless communication system. In some examples, multiple waveforms 220 can be used. For example, UE 115-a can receive signaling (e.g., from network entity 105-a) that can indicate a set of frequency resources that UE 115-a is to use for communication. For example, such a set of frequency resources can correspond to frequency resources 225-a, 225-b, or 225-c. Because different waveforms may be more suitable for different communication scenarios (e.g., different business types, different operating environments, different operating characteristics, different device capabilities, other aspects of the communication scenario, or any combination thereof), UE 115-a can send an indication of the business type (e.g., uplink communication) (e.g., to network entity 105-a), and the receiving device (e.g., network entity 105-a) can select or determine the waveform type to be used for communication in the resources 225 indicated to UE 115-a. Additionally or alternatively, the network entity 105-a may identify or select a traffic type (e.g., for downlink communications) and may select a waveform type independently of another device. Additionally or alternatively, a device (e.g., UE 115-a) may send an indication of capabilities associated with one or more waveform types, and the network entity 105-a may base selection or determination of one or more waveforms on the indication of capabilities.

[0108] The network entity 105-a may send (e.g., to the UE 115-a) an indication of the type of waveform that the UE 115-a is to use to communicate on the indicated resources 225. For example, the network entity 105-a may indicate the resources 225-a and the waveform 220-a to the UE 115-a. In some examples, the selected or determined waveform 220 may be indicated for use for a time period, such as the time period 230. For example, the network entity 105-a may have received or determined information indicating a condition or characteristic of the wireless communication system 200 that may be valid or sustainable for the time period 230, and therefore the UE 115-a may use the waveform 220-a during the time period 230 for communicating on the resources 225-a.

[0109] like Figure 2 As shown, other waveforms (e.g., waveforms 220-b and 220-c) may be used within the same bandwidth 235 as the waveform 220-a indicated to the UE 115-a. For example, a first additional wireless device (e.g., another UE) may communicate using waveform 220-b for communicating using resources 225-b, and a second additional wireless device (e.g., yet another UE) may communicate using waveform 220-c for communicating using resources 225-c. The additional devices may receive indications of the same time period 230 for communication, or may receive indications of different time periods. In this manner, the various waveforms 220 may be multiplexed or combined together for use within the bandwidth 235 of the wireless communication system 200. The UE 115-a (and optionally, the additional wireless devices) may communicate using the respectively indicated or selected waveforms 220 and resources 225, which are all within the bandwidth 235 of the wireless communication system 200.

[0110] Figure 3 An example of a processing scheme 300 for supporting hybrid waveform communications according to one or more aspects of the present disclosure is illustrated. The processing scheme 300 may describe one or more examples of processing associated with the transmission of one or more waveforms. For example, the processing scheme 300 shows an example of a transmitter 330-a for a UE using a time-domain based waveform and transmitters 330-b and 330-c using frequency-domain based waveforms and associated processing operations. In the processing scheme 300, the depicted operations may be performed at different times or in a different order. Some operations may be omitted, or other operations may be added. In addition, the depicted operations may also be performed in association with other elements of the processing scheme, even though such associations or operations may not be described in detail. Figure 3 The example depicted is shown.

[0111] exist Figure 3In the example, each transmitter 330 can be associated with a UE or other device that can transmit a waveform on which processing can be performed. In some examples, such a UE can perform processing on a waveform type indicated to the UE instead of performing processing on other waveform types. In addition, the various types of waveforms used by the various UEs can be multiplexed in the frequency domain within the bandwidth of the wireless communication system.

[0112] As described herein, various waveform types may be used. In general, waveform types may be divided into various groups of waveform types, including waveforms based on time-domain processing and waveforms based on frequency-domain processing. Furthermore, some waveform types may be processed or generated using a variety of techniques (e.g., time-domain processing, frequency-domain processing, or both). For example, some waveforms may be classified (e.g., depending on one or more associated processes or procedures) as both time-domain processed waveforms and frequency-domain processed waveforms. Additionally or alternatively, different waveforms within the categories of time-domain processed waveforms and frequency-domain processed waveforms may be processed differently.

[0113] For example, a waveform based on time domain processing may include a direct sequence waveform, where the decoded data symbol 310 may be multiplied with a spreading code (e.g., similar to the method used in a CDMA system), which may be an example of time domain processing 315. Such a direct sequence waveform may provide a reduced or lower PAPR compared to other waveforms (such as an OFDMA waveform) because multiple data symbols are not mixed in the final waveform (e.g., although pulse shaping 320 such as a pulse shaping filter may mix multiple data symbols to some extent). The transmitted signal of the direct sequence waveform may occupy a contiguous trunk or frequency resource set within the total bandwidth of the system. Additionally or alternatively, frequency hopping may be used to provide additional frequency diversity. Furthermore, synchronization and orthogonality parameters may be modified, increased, decreased, or relaxed, and autonomous transmission of the direct sequence waveform may also be used. Optionally, the processing may include cyclic prefix (CP) insertion 325.

[0114] Waveforms based on time domain processing may also include resource spread multiple access (RSMA) waveforms, in which multiple signals from multiple devices may be superimposed on each other, and one or more of the multiple signals may be spread over some or all of the resources (e.g., frequency resources, time resources, space resources, or any combination thereof) associated with or assigned to the multiple devices. For example, in upsampling or DFT repetition methods, The data symbol can be factored Upsample to form A long time domain sequence with M symbols distributed therein. The PAPR of such a waveform may be comparable to the PAPR of a direct stream waveform (e.g., reduced or lower PAPR compared to other waveforms such as OFDMA waveforms). In some examples, the RSMA method may include smoothing across the upsampled data samples, which may reduce the PAPR. In some examples, to fully utilize the frequency set, multiple devices may be scheduled together. Optionally, the processing may include CP insertion 325.

[0115] Waveforms based on time domain processing may also include sequence repetitive waveforms (e.g., upsampled DFT waveforms or distributed DFT-spread FDMA (DFT-s-FDMA)). In such waveforms, the M-ary DFT 335 may be applied Decoded data symbols 310 are provided. The DFT values ​​may be uniformly distributed (e.g., upsampled in frequency, such as by a factor of ) to form an N-element vector to which an IFFT is applied (e.g., N-element IFFT 345). In some examples, the PAPR of such a waveform can be comparable to the PAPR of a direct sequence waveform (e.g., a reduced or lower PAPR compared to other waveforms such as OFDMA waveforms). In some examples, the transmitted signal can be designed to span a larger bandwidth to achieve better frequency diversity. In some examples, to fully utilize the frequency set, multiple devices can be scheduled together. Optionally, the processing can include CP insertion 325.

[0116] Waveforms based on time domain processing may also include constant envelope waveforms. Such waveforms may include Gaussian minimum shift keying waveforms (e.g., those used in global system for mobile communications (GSM) and Bluetooth low energy applications, specifications or methods). Such waveforms may also include minimum shift keying waveforms (e.g., as used in some personal area networks) and minimum shift keying methods involving nonlinear modulation. These and other constant envelope waveforms may be associated with reduced PAPR, reduced spectral efficiency, or both. Optionally, the processing may include CP insertion 325.

[0117] The waveform based on frequency domain processing may also include a contiguous DFT-s-FDMA waveform, where an M-ary DFT 335 may be applied to decode the data symbol 310. The DFT values ​​may be placed consecutively to form an N-element vector (e.g., N-element IFFT 345) to which an IFFT is applied. Such waveforms may be associated with a lower PAPR than other waveforms (e.g., OFDMA waveforms), but may be higher than the PAPR of direct stream waveforms. In some examples, improved spectral efficiency may be obtained through frequency domain equalization at the receiver. Optionally, the processing may include CP insertion 325, zero padding 340 for forming an N-vector, or both.

[0118] Waveforms based on frequency domain processing may also include OFDMA waveforms, in which decoded data symbols 310 may be placed in the frequency domain. For example, transmitter 330-c may transmit an OFDMA waveform generated by using decoded data symbols 310, CP insertion 325, or any combination thereof. Waveforms based on frequency domain processing may also include frequency modulated continuous wave waveforms that can be used for sensing. By allocating frequency resources as frequency ramps, such waveforms may be modifications to OFDMA waveforms or included in the designation of OFDMA waveforms. Further modifications or variations of OFDMA may also be used, including various pre-coding variations that may be introduced across subcarriers. Optionally, processing may include CP insertion 325, zero padding 340 for forming an N vector, or both.

[0119] The frequency-domain processed waveform may also include a frequency-domain processed RSMA version, which may be obtained by performing an M-ary DFT 335 and repeating the Optionally, the processing may include CP insertion 325.

[0120] In some examples, a joint scheduling method or technique can be used to help schedule multiple waveforms for communication within the total bandwidth of the wireless communication system. Nominally, if the total bandwidth is occupied by pure OFDMA waveforms, subcarriers (e.g., using N-ary FFT, IFFT, or both). Some such methods may assume or employ an ODFMA chip duration of And the ODFMA symbol duration .

[0121] In examples of both waveforms based on time domain processing and waveforms based on frequency domain processing, the insertion of a CP (e.g., CP insertion 325) can implement an FFT with the entire bandwidth at the receiver. In some examples, including a CP may involve additional overhead, increase symbol-level synchronization with other frequency domain waveforms, or both. However, the insertion of a CP can provide the benefits of a frequency domain equalizer at the receiver. In the case of adopting CP insertion 325, autonomous transmission is still possible, but may be more affected by symbol timing parameters. In the case of not adopting CP insertion 325, the transmission time may be more flexible. In addition, in the case of no CP insertion 325, the receiving device may use additional resources to search for time domain signals, and for higher data rates, equalization may be more complex.

[0122] If multiple waveforms are mixed in the frequency domain, the entire bandwidth can be divided into multiple regions, where each region is mapped to one waveform. One or more frequency regions can be defined as component carriers, BWPs, other regions (e.g., a set of frequency resources signaled by control signaling such as RRC configuration, which is semi-static or dynamically scheduled by other control signaling such as MAC layer messages or PHY layer control channel messages), or any combination thereof. In some examples, the scheduling method may allow different waveforms to be used for uplink and downlink communications. For example, a direct stream waveform may be used for uplink communications, while OFDMA may be used for downlink communications. Different combinations or methods may be better suited for different applications, service types, or other variables or characteristics (e.g., satellite communications may use direct stream waveforms for uplink communications and OFDMA waveforms for downlink communications).

[0123] In some examples (e.g., Figure 3 ), one or more waveforms associated with time domain processing may be multiplied by a center frequency , optionally, with guard subcarriers on one or both sides of the allocated frequency region.

[0124] As described herein, frequency resources may be allocated for different waveforms, and various factors may affect the frequency resource allocation. One such factor may include PAPR, which may affect the frequency resource allocation for uplink, downlink, or both or may be a factor on which the frequency resource allocation for uplink, downlink, or both may be based. In some examples, OFDMA may provide increased spectral efficiency and improved MIMO schemes. UEs or other devices associated with PAPR restrictions may be placed in an area according to one or more preferences or orders. For example, one such preference may adopt the following waveform preference order: direct stream / upsampling (DFT repetition) / sequence repetition (distributed DFT-s-FDMA), contiguous DFT-s-FDMA, and OFDMA. In some examples, the direct stream waveform may include one or more advantages, including the advantages of relaxing synchronization and orthogonality parameters. Therefore, the direct stream waveform may be suitable for low-latency, low-data rate services (e.g., control information, voice, other low-latency services, or any combination thereof).

[0125] In some wireless communication systems, the methods described herein may be used in MIMO scenarios. The first MIMO method may involve the use of sub-band MIMO with OFDMA. Such methods may be particularly suitable for channels with high MIMO rank, wide bandwidth (e.g., so that the frequency selectivity in the MIMO codeword is not negligible), or both. Additionally or alternatively, the MIMO method may adopt continuous DFT-s-FDMA that can be used in uplink MIMO situations. Additionally or alternatively, the MIMO method may adopt the use of time domain waveforms. Such methods may be particularly beneficial when the channel is not selective in the bandwidth used by the waveform. MIMO in a universal mobile telecommunications system (UMTS) scenario may be an example use case. Additionally or alternatively, the MIMO method may be used in higher frequency systems (e.g., such as those in the sub-THz range). In such methods, lenses may be used to implement MIMO in line-of-sight channels. In addition, the frequency selectivity of the channel used may be low, so that MIMO can be implemented for time domain waveforms and frequency domain waveforms.

[0126] As described herein, the method of using multiple waveforms may be applied to both uplink operations and downlink operations. In some downlink operations, the waveform used may be an OFDMA waveform, which may not utilize the mixing or multiplexing of multiple waveforms in the total bandwidth of the system. However, there is no precluded use of multiple waveforms for downlink operations, and such systems may use the methods described herein (e.g., to improve PAPR metrics in the system). In some downlink scenarios, a transmitting device may use one waveform at a time, and a receiving device may process the one waveform, and optionally may not perform processing associated with other waveforms. However, multiple downlink transmitting devices may use different waveforms that may be multiplexed within a frequency resource, similar to the methods described herein for uplink transmitting devices.

[0127] Figure 4 An example of a processing scheme 400 for supporting hybrid waveform communications in accordance with one or more aspects of the present disclosure is illustrated. The processing scheme 400 describes different options for processing that may be performed at a receiving device in a wireless communication system that utilizes the methods described herein for use of multiple waveforms within the total bandwidth of the wireless communication system. Because different waveforms may have different characteristics and various processing methods may have been used to generate and transmit the waveforms, various processing methods may be applied at the receiving device to appropriately interpret and process the transmission to obtain the information in the transmission. Such processing steps may vary between scenarios, specific implementations, waveform types, or other scenarios as described herein. In the processing scheme 400, the operations depicted may be performed at different times or in different orders. Some operations may be omitted, or other operations may be added. In addition, the operations depicted may also be performed in association with other elements of the processing scheme, even though such associations or operations may not be described in detail. Figure 4 The example depicted is shown.

[0128] Figure 4 The upper branch depicted in FIG. 4 (ultimately leading to data decoding 440 - a) may be associated with processing of waveforms based on time domain processing and may be associated with processing of waveforms based on time domain processing. Figure 3 The above-described transmission processing associated with the transmitter 330-a is associated. In such a scenario, the receiver 410 may receive the transmission and may optionally perform CP removal 415 to remove the cyclic prefix from the transmission to facilitate further processing. In some examples, CP removal 415 may not be performed, and the signal may then be processed to reversely apply the center frequency to the signal. Additionally or alternatively, CP removal 415 may be performed and an FFT 420 operation may be performed, after which the inversion of the application of the center frequency may be performed. A low pass filter 445 may be applied to the signal, and an IDFT 450 procedure or processing may be performed on the signal, after which time domain processing 455, sequence despreading 460, or both may be performed. For example, different waveforms may utilize time domain processing 455, while other waveforms (e.g., RSMA waveforms) may utilize sequence despreading 460. In some examples, data decoding 440-a may then be performed.

[0129] Figure 4 The intermediate branch in (ultimately leading to data decoding 440-b) may be associated with the processing of waveforms based on frequency domain processing and may be related to the above Figure 3 The described associated with the transmission processing of the transmitter 330-b. In such a scenario, the receiver 410 can receive the transmission and CP removal 415 can be performed to remove the cyclic prefix from the transmission for further processing. FFT 420 processing can be applied, after which filtering 425 can be performed to form an N' vector. Subband selection 430 can be performed to form an M' element vector, after which an M' element IDFT 435 can be performed. The "prime" notation of "M' element" or "N' element" (as opposed to "M element" or "N element") is used herein and in the accompanying drawings to indicate the receiving side reconstruction of the original signal, vector or other element. Data decoding 440-b can then be performed to obtain the information or data of the transmission.

[0130] Figure 4 The lower branch in (ultimately leading to data decoding 440-c) may be associated with processing of waveforms based on frequency domain processing and may be associated with the ... Figure 3 The above is associated with the transmission processing of the transmitter 330-c. In such a scenario, the receiver 410 can receive the transmission and can perform CP removal 415 to remove the cyclic prefix from the transmission for further processing. FFT 420 processing can be applied, and then data decoding 440-b can be performed to obtain the information or data of the transmission.

[0131] In some cases, FFT 420 processing may be performed for a portion of the bandwidth (e.g., time domain processing may be performed for some waveforms). Further, in some examples, waveforms based on time domain processing may occupy or use frequency resources that may be at the edge of the total bandwidth of the device or wireless communication system. Additionally or alternatively, where multiple types of waveforms are multiplexed in frequency resources, FFT 420 processing may be performed for the entire bandwidth of the device or wireless communication system. In some such cases, CP may be added to the time domain waveform transmission. Further, a receiving device (e.g., a network entity) may perform processing on waveforms used in transmissions to be received, and may not perform processing on other types of waveforms that are not used for transmission and reception.

[0132] Figure 5 An example of a process flow 500 for supporting hybrid waveform communications according to one or more aspects of the present disclosure is illustrated. The process flow 500 may implement various aspects of the present disclosure described herein. The elements described in the process flow 500 (e.g., the network entity 105-b and the UE 115-b) may be examples of similarly named elements described herein.

[0133] In the following description of process flow 500, operations between various entities or elements may be performed in different orders or at different times. Some operations may also be excluded from process flow 500, or other operations may be added. Although various entities or elements are shown as performing operations of process flow 500, some aspects of some operations may also be performed by other entities or elements of process flow 500 or by entities or elements not depicted in the process flow, or any combination thereof.

[0134] At 520, UE 115-b may receive an indication of a set of frequency domain resources allocated to the UE for communicating data on a wireless channel. In some examples, the set of frequency domain resources occupies the entire bandwidth portion. In some examples, the set of frequency domain resources occupies a portion of the bandwidth portion.

[0135] At 525, for uplink traffic, UE 115-b may send an indication of a traffic type associated with communicating on the wireless channel. At 525, for downlink traffic, the network is aware of the traffic type.

[0136] At 530, UE 115-b may receive an indication of a waveform type associated with the set of frequency-domain resources, wherein the waveform type is based on a data type of the data, is to be used for a defined amount of time, and is one of a plurality of waveform types that are multiplexed together on different frequency-domain resources within an overall system bandwidth. In some examples, receiving the indication of the waveform type may be based on a peak-to-average power ratio metric associated with the UE.

[0137] In some examples, the multiple waveform types multiplexed together on different frequency domain resources within the total system bandwidth may include a combination of one or more waveforms based on frequency domain processing and one or more waveforms based on time domain processing. In some examples, the one or more waveforms based on time domain processing include one or more of a direct sequence waveform, a resource extension multiple access waveform, an up-sampled waveform, a distributed Fourier spread waveform, a constant envelope waveform, or any combination thereof. In some examples, the one or more waveforms based on time domain processing occupy frequency domain resources located at the edge of the total system bandwidth.

[0138] In some examples, the waveform type may be a direct sequence waveform type, and the set of frequency domain resources may include multiple contiguous subbands of the total system bandwidth. In some examples, the waveform type may include one or more of a distributed Fourier spread waveform type or an upsampled waveform type. In some examples, the one or more frequency domain processing-based waveforms include one or more of a contiguous Fourier spread waveform, an orthogonal frequency domain multiple access waveform, a frequency modulated continuous wave waveform, or any combination thereof.

[0139] At 535, the UE 115-b may receive scheduling information associated with the direct sequence waveform type, the scheduling information including a center frequency, a chip rate, a spreading factor, a data rate, or any combination thereof.

[0140] At 540, the UE 115-b may process the cyclic prefix associated with the direct sequence waveform type.

[0141] At 545, UE 115-b may communicate within the set of frequency-domain resources in accordance with the indicated waveform type and data type. In some examples, UE 115-b may communicate within the set of frequency-domain resources in accordance with a direct sequence waveform type and scheduling information.

[0142] Notice, Figure 5 Communication in the CAN bus may occur on the downlink or uplink.

[0143] Figure 6 A block diagram 600 of a device 605 supporting hybrid waveform communications according to one or more aspects of the present disclosure is shown. The device 605 may be an example of aspects of the UE 115 as described herein. The device 605 may include a receiver 610, a transmitter 615, and a communication manager 620. The device 605 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0144] Receiver 610 may provide means for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with hybrid waveform communications). The information may be communicated to other components of device 605. Receiver 610 may utilize a single antenna or a collection of multiple antennas.

[0145] The transmitter 615 may provide means for transmitting signals generated by other components of the device 605. For example, the transmitter 615 may transmit information associated with various information channels (e.g., control channels, data channels, information channels related to hybrid waveform communications), such as packets, user data, control information, or any combination thereof. In some examples, the transmitter 615 may be co-located with the receiver 610 in a transceiver module. The transmitter 615 may utilize a single antenna or a collection of multiple antennas.

[0146] The communication manager 620, the receiver 610, the transmitter 615, or various combinations thereof or various components thereof may be examples of means for performing various aspects of hybrid waveform communications as described herein. For example, the communication manager 620, the receiver 610, the transmitter 615, or various combinations thereof or components thereof may support methods for performing one or more of the functions described herein.

[0147] In some examples, the communication manager 620, the receiver 610, the transmitter 615, or various combinations or components thereof may be implemented in hardware (e.g., in a communication management circuit). The hardware may include a processor, a digital signal processor (DSP), a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic components, discrete hardware components, or any combination thereof that is configured as or otherwise supports components for performing the functions described in the present disclosure. In some examples, the processor and a memory coupled to the processor may be configured to perform one or more of the functions described herein (e.g., by executing instructions stored in the memory by the processor).
