Technical Field

[0003] The following relates to wireless communications, including constellation-based resource allocation for sensing and communication. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. 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 communication for a communication device, which may be referred to as a user equipment (UE).

[0005] The wireless communication system may support sensing (e.g., radar) applications, in which a sensing device may reflect signaling from a target (e.g., an opaque object) to determine one or more characteristics associated with the target. For example, in single-base sensing, a sensing device may send a waveform in the direction of a target. The target may reflect the waveform that may be received by the sensing device. The sensing device may determine the distance, angle, speed, or other parameters of the target based on the received waveform. In some cases, the sensing device may use the same waveform configuration to send both radar signaling and communication-based signaling, which may be referred to as joint communication and sensing (JCS). In some cases, the achievable sensing resolution and accuracy may be limited by the communication parameters used to send the JCS waveform. Summary of the invention

The transmitting device may map the first portion of the data to a first subset of REs associated with sensing in the set of REs. In addition, the transmitting device may map the second portion of the data to a second subset of REs associated with data communication in the set of REs. The transmitting device may send the transmission block including the mapped first portion of the data and the second portion of the data to a receiving device, and the receiving device may demodulate the transmission block based on the first modulation scheme and the second modulation scheme. In some examples, the transmitting device may perform a sensing process using the first subset of REs.

[0058] A wireless device (user equipment (UE), network entity, etc.) may use radar, sensing, ranging, and positioning processes to identify, track, or locate a target object, and determine characteristics or attributes of the target object, such as direction, speed, etc. For example, a wireless device may send a waveform in one or more directions and may monitor the reflection of the waveform. The waveform may be reflected from one or more objects and received back at a receiver of the wireless device after a time delay. The wireless device may detect or otherwise identify the target object based on the received waveform. For example, the time delay between transmission and reception may be proportional to the distance between the wireless device and the detection object from which the waveform is reflected. In some examples, a sensing process (which may include a ranging process, a positioning process, etc. or may be an example thereof) may utilize a digital waveform, such as an orthogonal frequency division multiplexing (OFDM) based waveform.

[0059] In a joint communication and sensing (JCS) application (also referred to as a joint communication and radar (JCR) application), a common transmitter or receiver may be used for both communication and radar functionality, and a communication waveform (such as OFDM) may also be used for radar sensing. That is, a JCS application may use the same (e.g., common) waveform to convey data and perform sensing, rather than using separate waveforms for data communication and sensing processes, which may reduce communication throughput (e.g., because resources used for the sensing waveform are no longer available for data communication). For example, a transmitting device may send a JCS waveform carrying data information to a receiving device, where the JCS waveform is also used for a sensing process (e.g., a monostatic sensing process, a bistatic sensing process). The transmitting device may monitor reflections of the JCS waveform and detect a target object. A JCS application may improve efficiency while avoiding the throughput costs associated with utilizing a dedicated sensing waveform.

[0060] However, communication parameters that provide optimal performance for data communications may conflict with communication parameters associated with improved sensing. For example, in data communications, higher order modulation schemes may support relatively higher data rates and increased throughput. Compared to lower order or constant modulus modulation schemes, such modulation schemes may be associated with increased noise when receiving or processing sensing signals, which may degrade the performance and accuracy of the sensing process. Therefore, a JCS waveform transmitted with a higher order modulation scheme may achieve a relatively high data rate, but may suffer from reduced performance in the corresponding sensing process. Alternatively, a JCS waveform transmitted with a lower order or constant modulus modulation scheme may provide improved performance in the sensing process, but may have a relatively low throughput.

[0061] The techniques described herein support configuring communications using a JCS waveform to provide balanced performance in both data communications and sensing. For example, a transmitting device may utilize multiple modulation schemes for a data transmission block to be communicated via a JCS waveform, and may transmit the transmission block using a set of resource elements (REs) including sensing REs and data REs (e.g., data-only REs that may not be used for sensing). The transmitting device may modulate a first portion of the data of the transmission block according to a first modulation scheme, wherein the first modulation scheme is from a set of modulation schemes used for sensing, and may map the first portion of the data to the sensing REs. The transmitting device may modulate a second portion of the data of the transmission block according to a second modulation scheme (e.g., different from the first modulation scheme), and may map the second portion of the data to the data REs. The sensing REs carrying the first portion of the data may be used by the transmitting device to perform a sensing process.

[0062] In some examples, the transmitting device may implement one or more parameters for the configuration of the JCS waveform, such as an RE pattern for mapping data to a sensing RE, a transmit power for a sensing RE, a transmit power for a data RE, and the like, as well as other examples. The first modulation scheme and the second modulation scheme may also be considered to be parameters of the configuration. In order to enable the receiving device to receive and decode the JCS waveform according to the configuration, the transmitting device may indicate one or more parameters via control signaling. Additionally, in some cases, the transmitting device may indicate (e.g., via control signaling) whether to use the JCS waveform to transmit an upcoming transmission using two different modulation schemes on two sets of REs, as described herein. The receiving device may respond to the control signaling by sending an indication of support for the configuration, one or more parameters supported by the receiving device, or a combination thereof.

[0063] Aspects of the disclosure are first described in the context of a wireless communication system. Aspects of the disclosure are then discussed with reference to RE configurations and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to constellation-based resource allocation for sensing and communication.

[0064] Figure 1 An example of a wireless communication system 100 supporting constellation-based resource allocation for sensing and communication 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).

[0065] 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 names. 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), and the UE 115 and the network entity 105 may establish one or more communication links 125 over the coverage area. The coverage area 110 may be an example of a geographic area, and the network entity 105 and the UE 115 may support signal communications over the geographic area according to one or more radio access technologies (RATs).

[0066] 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 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 Communicate with other UEs 115 or network entities 105) as shown.

[0067] 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.

[0068] 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 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 directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130) via the backhaul communication link 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, the network entities 105 may communicate with each other via the midhaul communication link 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication link 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, the midhaul communication link 162, or the fronthaul communication link 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), or other examples or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0069] 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 terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) 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).

[0070] 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)).

[0071] The functional split between CU 160, DU 165, and RU 170 is flexible and can support different functionalities, 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 can be employed between CU 160 and DU 165, such that CU 160 can support one or more layers of a protocol stack and DU 165 can support one or more different layers of a protocol stack. In some examples, CU 160 can 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 CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by the other of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and 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 based on interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 that communicate via those communication links.

[0072] 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 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 donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140). One or more donor network entities 105 (e.g., IAB donors) 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 donor. 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.

[0073] For example, an access network (AN) or RAN may include an access node (e.g., an IAB donor), communications between an IAB node 104, and one or more UEs 115. The IAB donor may facilitate a connection 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 donor may refer to a RAN node having a wired or wireless connection to the core network 130. The IAB donor 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 donor and the IAB node 104 may communicate via an F1 interface according to a protocol defining a signaling message (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 donor) via an Xn-C interface (which may be an example of a portion of a backhaul link).

[0074] 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 donor may be referred to as a parent node that communicates with one or more child nodes (e.g., an IAB donor 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 .

[0075] For example, the IAB node 104 may be referred to as a parent node supporting communications for a child IAB node or as a child IAB node associated with an IAB donor, or both. The IAB donor 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 donor may relay transmission to the UE 115 through the IAB node 104, or may directly signal the transmission to the UE 115, or both. The CU 160 of the IAB donor 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 donor 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 to the MT of the IAB node 104. Communications with the IAB node 104 may be scheduled by the DU 165 of the IAB donor, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .

[0076] In the case where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support constellation-based resource allocation for sensing and communication 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 decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0077] 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 terminology, 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.

[0078] 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.

[0079] 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 defined physical layer structure 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 to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between a device 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 the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0080] 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 according to a channel raster for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be performed by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case the connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0081] 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).

[0082] 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, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). A device of the wireless communication system 100 (e.g., a network entity 105, a UE 115, or both) may have a hardware configuration that supports communications using a particular carrier bandwidth, or may be capable of being configured to support communications using one of a 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 a carrier bandwidth.

[0083] The signal waveform transmitted via the carrier may be composed of 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, RE 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 number of bits carried by each RE 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 number of REs (e.g., in the transmission duration) and a relatively high-order modulation scheme 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, beams), and the use of multiple spatial resources may increase the data rate or data integrity of communication with UE 115.

[0084] 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 T s =1 / (Δf max ·N f ) seconds, where Δfmax It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. The 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).

[0085] 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 multiple 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 multiple symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, the time slot may also be divided into multiple mini-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0086] A subframe, a time slot, a mini-time slot, or a 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 number 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 bursts of shortened TTIs (sTTIs)).

[0087] Physical channels may be multiplexed using carriers for communication according to various techniques. For example, physical control channels and physical data channels may be multiplexed via downlink carriers for signaling 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)) for a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search a 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 a control channel candidate 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 a plurality of UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0088] The network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, 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 a 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.

[0089] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to a UE 115 that has a service subscription with a network provider that supports the macro cell. A small cell may be associated with a lower power network entity 105 (e.g., a lower power base station 140) than a macro cell, and the small cell may operate using the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to a UE 115 that has a service subscription with a network provider, or may provide restricted access to a UE 115 associated with a small cell (e.g., a UE 115 in a closed subscriber group (CSG), a UE 115 associated with a user 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.

[0090] 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.

[0091] 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.

[0092] 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 with integrated sensors or meters to measure or capture 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.

[0093] 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 communication may include private communication or group communication, 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 applications or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency are used interchangeably herein.

[0094] 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 various aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 of 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 conducted between UEs 115 without involving network entity 105.

[0095] 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.

[0096] 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 for managing access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity for routing packets or interconnecting to an external network (e.g., a serving gateway (S-GW)), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered via the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to an IP service 150 for 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.

[0097] 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). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is approximately one decimeter to one meter. 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 services 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 lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0098] The wireless communication system 100 may utilize both licensed RF spectrum bands and unlicensed RF spectrum bands. For example, the wireless communication system 100 may employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology using unlicensed bands such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating using unlicensed RF spectrum bands, devices such as network entities 105 and UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands may be based on carrier aggregation configuration in combination with component carriers operating using licensed bands (e.g., LAA). Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0099] 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) communications, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels that can 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 rows and columns of antenna ports 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 can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0100] 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 technology may be referred to as spatial multiplexing. Multiple signals may be, for example, sent by a transmitting device via different antennas or different combinations of antennas. Similarly, 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.

[0101] 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 steer 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 the 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).

[0102] The network entity 105 or UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with 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 network entity 105), or by a receiving device (such as UE 115)) beam directions for later transmission or reception by the network entity 105.

[0103] Some signals, such as data signals associated with a particular receiving device, may be sent 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 sent 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.

[0104] 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 be precoded or non-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).

[0105] 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 the 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 the 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).

[0106] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication 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 processing and multiplexing of logical channels to 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 that supports a radio bearer for user plane data between the UE 115 and the network entity 105 or the core network 130. The PHY layer may map a transport channel to a physical channel.

[0107] 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 via 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.

[0108] The wireless communication system 100 may support radar devices and processes. For example, devices in the wireless communication system 100, such as the network entity 105, the UE 115, etc., may reflect radar signaling from a target (e.g., an opaque object) to determine one or more characteristics associated with the target. For example, the UE 115 may send a waveform in one or more directions. The waveform may be reflected by one or more targets. After receiving the reflection of the waveform, the UE 115 may identify one or more physical properties of the radar target. That is, the reflection of the waveform may indicate the physical properties of the radar target. Specifically, the UE 115 may determine the values ​​of one or more radar measurement parameters of the radar target (e.g., position, velocity, size, orientation, and uncertainty values ​​of each value).

[0109] The performance of the radar may be measured or evaluated based on one or more performance parameters. In some cases, the one or more performance parameters may include key performance indicators (KPIs). For example, resolution, estimation accuracy, maximum and minimum range, maximum and minimum Doppler shift, field of view (FoV), maximum number of detected targets, update rate, and update rate delay may be examples of KPIs. Additionally or alternatively, signal to interference plus noise ratio (SINR) and other interference-based parameters may be examples of KPIs. In some cases, one or more KPIs may be used to evaluate the radar based on the automotive application and environment.

[0110] Similar processes can be used for sensing, ranging and positioning applications. For example, a device in the wireless communication system 100 can use a positioning reference signal (PRS) or a sounding reference signal (SRS) to determine parameters (e.g., position, speed, size, orientation, etc.) of one or more other devices in the wireless communication system 100 or sense the environment of the wireless communication system 100. In some examples, a sensing process (which may include a ranging process, a positioning process, etc. or may be an example of them) may utilize a digital waveform, such as an OFDM-based waveform. A single-base sensing process may be performed by a single device that sends a sensing waveform and monitors reflections to detect a target object. A dual-base sensing process may be performed by a transmitter and a receiver separated by a certain distance (e.g., not co-located). For example, a transmitting device may send a sensing waveform and a receiving device (e.g., different from the transmitting device) may receive the sensing waveform and detect one or more target objects. In some cases, a receiving device may determine information about a target object (e.g., distance, speed, etc.) by performing channel estimation on multiple OFDM symbols (e.g., consecutive OFDM symbols) of the sensing waveform.

[0111] In JCS applications, the same waveform may be used to both communicate data and perform sensing, which may improve efficiency in resource utilization. JCS applications may utilize JCS waveforms as part of monostatic sensing, bistatic sensing, and the like. For example, a device in the wireless communication system 100 may send data via a JCS waveform, and may perform a sensing process using the JCS waveform. In some examples, the device may treat the data sent via the JCS waveform as a sensing reference signal for the sensing process, and may monitor reflections to detect target objects, perform channel estimation, and the like, as well as other examples.

[0112] For example, the device may calculate (e.g., estimate) a channel impulse response (CIR) based on a reflection of a received JCS waveform. The device may determine a CIR estimate based on known characteristics of the JCS waveform, a channel frequency response measured at the device, and any additive noise. The device may calculate the CIR by transforming the channel frequency response to the time domain. However, if the device uses a higher-order modulation scheme such as a quadrature amplitude modulation (QAM) scheme to transmit the JCS waveform to achieve a relatively high data rate, the sensing process may suffer from performance degradation due to increased noise. The noise is introduced when estimating the channel frequency response and equalizing the received sensing REs by the (higher-order) constellation symbols transmitted on the REs. That is, higher-order modulation schemes may be associated with lower signal-to-noise ratios (SNRs), which may make accurate channel estimation difficult. As illustrated in Table 1 below, transmission using a higher-order QAM scheme may be associated with increased noise compared to transmission using a constant modulus modulation scheme (e.g., QPSK), which may reduce the accuracy of sensing. Note that while Table 1 corresponds to forced-zero equalization, other types of equalization may be used to produce similar SNR degradation.

[0113] QAM Order SNR loss compared to QPSK 16 2.76dB 64 4.29dB 256 5.36dB 1024 6.20dB 4096 6.90dB

[0114] Table 1

[0115] Improved sensing performance can be achieved using a lower order or constant modulus modulation scheme, although such modulation schemes can reduce the data rate and throughput of the JCS waveform. Therefore, in some other examples, the JCS waveform may be associated with one or more reference signal REs. For example, the device may send a JCS waveform via a set of REs including a first subset of REs for reference signals and a second subset of REs for carrying data, and the reference signal REs may be used to perform a sensing process. The first subset of REs may be associated with a frequency comb (e.g., comb 2 mode, comb 4 mode) so that each OFDM symbol of the JCS waveform includes a reference signal RE. The device may modulate the reference signal RE according to a lower order or constant modulus modulation scheme to avoid performance degradation. Additionally, when the reference signal RE has a relatively high density in both the frequency domain and the time domain, the sensing process may be associated with improved performance and accuracy. However, in such examples, utilizing the reference signal RE may reduce throughput because the reference signal RE is no longer available for data transmission. Therefore, the device may determine the tradeoff between the sensing performance and communication throughput of the JCS waveform.

[0116] According to the techniques described herein, a transmitting device (e.g., a network entity 105, a UE 115) may adjust or configure a JCS waveform to transmit data at a relatively high throughput (e.g., a data rate) while maintaining sensing accuracy. The transmitting device may utilize different modulation schemes for different portions of a transport block associated with a JCS waveform, and may perform sensing based on data of the transport block transmitted via the JCS waveform (e.g., rather than performing sensing based on reference signals REs associated with the JCS waveform). For example, the transmitting device may transmit data of a transport block via a JCS waveform such that a first set of REs is associated with sensing, and data mapped to the first set of REs is modulated according to a first modulation scheme. A second set of REs may be associated with data communication, and the transmitting device may modulate data mapped to the second set of REs according to a second modulation scheme. The first modulation scheme may support improved performance in a sensing process performed by the transmitting device using the first set of REs. For example, the first modulation scheme may be a constant modulus modulation scheme or a lower order modulation scheme. The second modulation scheme may be a relatively higher order modulation scheme that may support a higher data rate, so that the transmitting device may transmit data on a second set of REs at a relatively high throughput. By multiplexing modulation schemes within the same transmission block of a JCS waveform, a transmitting device can achieve desired performance results for both communication and sensing.

[0117] Additionally, in some cases, the transmitting device may select one or more parameters (e.g., waveform parameters) for the configuration of the JCS waveform (e.g., JCS waveform configuration). The one or more parameters may include, but are not limited to, a first modulation scheme, a second modulation scheme, a RE pattern for a first set of REs, a transmit power for a first set of REs, a transmit power for a second set of REs, a number of time domain resources for configuration, a periodicity of configuration, a time duration of configuration, and the like, as well as other examples. In order to enable the receiving device to successfully receive the JCS waveform and decode the JCS waveform, the transmitting device may send an indication of one or more parameters to the receiving device, and the receiving device may monitor the JCS waveform according to the one or more parameters. That is, the transmitting device may generate and send a JCS waveform according to the indicated waveform parameters. The receiving device may receive, demodulate, and decode the JCS waveform based on the indicated waveform parameters.

[0118] In some examples, a transmitting device and a receiving device may exchange capability information associated with JCS waveform parameters. For example, a transmitting device may indicate to a receiving device the capability of the transmitting device to communicate using a JCS waveform and one or more JCS waveform parameters supported by the transmitting device. In response to the indication, the receiving device may send a message indicating the capability of the receiving device to support the JCS waveform and one or more JCS waveform parameters supported by the receiving device, so that the transmitting device may consider the capability of the receiving device when determining a configuration (e.g., selecting one or more parameters) for the JCS waveform.

[0119] Additionally or alternatively, the receiving device may determine and indicate one or more preferred JCS waveform parameters based on the capabilities of the receiving device and, in some cases, based on tradeoffs associated with the preferred JCS waveform parameters. For example, some waveform parameters may be associated with increased power consumption, reduced data throughput, etc., and the receiving device may select the preferred waveform parameters accordingly. The receiving device may indicate the preferred waveform parameters to the transmitting device, which may configure the JCS waveform based on the preferred waveform parameters.

[0120] Figure 2 An example of a wireless communication system 200 supporting constellation-based resource allocation for sensing and communication according to one or more aspects of the present disclosure is illustrated. For example, the wireless communication system 200 may include a network entity 105-a and a UE 115-a, which may be as described in reference Figure 1 The network entity 105-a and the UE 115-a may communicate via the communication link 215, which may be as described in reference Figure 1 Examples of communication links 125 described. For example, the wireless communication system 200 may include an uplink communication link 215-a and a downlink communication link 215-b, which may be examples of communication links 125. The uplink communication link 215-a may include one or more uplink channels or may be examples of one or more uplink channels, such as a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), etc. The downlink communication link 215-b may include one or more downlink channels or may be examples of one or more downlink channels, such as a physical downlink shared channel (PDSCH), a physical downlink control channel (PDCCH), etc.

[0121] Although described as communications between a UE 115-a and a network entity 105-a, any type or number of devices may implement the techniques described herein (e.g., multiple UEs 115, IoT devices, roadside units (RSUs), network entities 105, centralized controller nodes, or any combination thereof, as well as other examples of wireless devices). For example, although Figure 2 A single-base sensing process is illustrated as being performed with the network entity 105-a as a transmitting device and the UE 115-a as a receiving device, but any device or any type of device may act as a transmitting device or a receiving device. For example, the single-base sensing process may be performed via a sidelink channel (e.g., a physical sidelink shared channel (PSSCH)) between two UEs 115, between two network entities 105, and the like, as well as other examples, or the UE 115-a may act as a transmitting device and the network entity 105-a may act as a receiving device. In addition, the techniques described herein may be extended to dual-base or other sensing processes using any number of devices. Additionally, although the examples herein refer to sensing processes, the methods and techniques described may be applied to any ranging, positioning, or radar application.

[0122] In some cases, UE 115-a, network entity 105-a, or both may be examples of vehicles (e.g., vehicles in a vehicle-to-everything (V2X) network). As described herein, UE 115-a and network entity 105-a may each be capable of sending and receiving both radar (e.g., sensing) signaling (e.g., for performing sensing, estimating characteristics associated with nearby objects, etc.) and communication-based signaling (e.g., data and control signaling). For example, UE 115-a and network entity 105-a may support JCS waveforms, where data communicated via the JCS waveform is also used for sensing. That is, a portion or all of a JCS waveform used for data communication may be considered a sensing reference signal. In some examples, network entity 105-a and UE 115-a may support configurations for JCS waveforms including one or more waveform parameters, and may exchange signaling to coordinate waveform parameter selection.

[0123] exist Figure 2 In an example of a JCS waveform 230, the network entity 105-a may send a message 220 to the UE 115-a to indicate a configuration and one or more parameters for a subsequent JCS waveform (e.g., a JCS waveform 230) to be sent by the network entity 105-a. The UE 115-a may send a message 225 indicating whether the UE 115-a supports the configuration and the one or more parameters in response to the message 220. In some cases, the message 220 may additionally or alternatively indicate one or more waveform parameters supported or preferred by the UE 115-a. The network entity 105-a may send the JCS waveform 230 to the UE 115-a according to the configuration. The JCS waveform 230 may be an example of an OFDM-based waveform (e.g., an OFDM-based signal, such as a cyclic prefix OFDM (CP-OFDM) signal), and in some examples, may be an OFDM-based radar waveform. The JCS waveform may include data communications and may be sent via a data channel such as a PDSCH, a PUCCH, or a PSSCH.

[0124] Network entity 105-a may transmit JCS waveform 230, cause portion 235 of JCS waveform 230 to reflect from object 205, and receive reflection 240 (e.g., of JCS waveform 230) at network entity 105-a. Figure 2 In the example of , portion 235 may be JCS waveform 230 transmitted by network entity 105-a, and reflection 240 may be JCS waveform 230 as received by network entity 105-a, for example, after being reflected from object 205. Network entity 105-a may perform sensing based on receiving reflection 240.

[0125] For example, the network entity 105-a may calculate or otherwise determine one or more parameters or characteristics associated with the object 205. The network entity 105-a may determine the position (e.g., location), orientation, size, etc. of the object 205, the distance or angle between the network entity 105-a and the object 205, the speed of the object 205, the Doppler or delay associated with the object 205, etc. For example, the network entity 105-a may determine the distance between the network entity 105-a and the object 205 based on the path delay associated with the reflection 240. The network entity 105-a may determine the speed of the object 205 based on determining the Doppler shift on the symbol (e.g., OFDM symbol) of the reflection 240. In some cases, the network entity 105-a may additionally determine an uncertainty value for each parameter or characteristic of the object 205. Additionally or alternatively, the network entity 105-a may perform channel estimation based on the transmitted JCS waveform 230 and the reflection 240. For example, the network entity 105 - a may calculate (eg, estimate) a channel impulse response (CIR) based on the reflections 240 from the object 205 .

[0126] According to the techniques described herein, when sending the JCS waveform 230, the network entity 105-a can utilize REs dedicated to sensing (e.g., sensing REs) (e.g., time resources, frequency resources) and REs dedicated to data (e.g., data-only REs). The network entity 105-a can adjust communication parameters on the sensing REs and the data-only REs to achieve appropriate performance for sensing and data communications, respectively. That is, the network entity 105-a can select parameters that support improved accuracy and resolution of the sensing process for sending data on the sensing REs, and can select parameters that provide relatively high throughput and data rate for sending data on the data-only REs.

[0127] For example, the network entity 105-a may transmit a transport block via the JCS waveform 230, wherein the transport block includes at least a first portion of data and a second portion of data transmitted on a first set of REs and a second set of REs, respectively. The network entity 105-a may perform sensing based on the first set of REs. Therefore, the REs (e.g., the first set of REs) used by the network entity 105-a to perform sensing may carry data instead of a preconfigured sequence associated with a reference signal, which may avoid a reduction in throughput associated with the reference signal REs. Additionally, in order to prevent sensing performance degradation associated with a higher-order modulation scheme, the network entity 105-a may modulate the first portion of the data according to a first modulation scheme from a set of modulation schemes used for sensing. Furthermore, in order to avoid a reduction in data rate and throughput, the network entity 105-a may modulate the second portion of the data according to a second modulation scheme used for data communication (e.g., different from the first modulation scheme).

[0128] The set of modulation schemes used for sensing may include modulation schemes associated with relatively low noise such as QPSK, phase shift keying (PSK), one or more constant modulus schemes, one or more lower order modulation schemes (e.g., 16-QAM), or a subset of a higher order modulation scheme (e.g., a four-symbol subset of 64-QAM). In contrast, the second modulation scheme used for data communication may be a relatively higher order modulation scheme, such as 64-QAM, 256-QAM, 1024-QAM, 4096-QAM, etc., as well as other examples.

[0129] The network entity 105-a may map a first portion of the modulated data to a first set of REs, and may map a second portion of the data to a second set of REs. The network entity 105-a may send a transport block including the first portion and the second portion of the mapped data via the JCS waveform 230. To perform the sensing process, the network entity 105-a may monitor the first set of REs for reflections 240. The network entity 105-a may perform channel estimation (e.g., for the communication link 215-a, the communication link 215-b, or both) based on receiving the reflections 240. For example, the network entity 105-a may use the reflections 240 to perform measurements to determine a CIR associated with the channel over which the JCS waveform is sent.

[0130] In some examples, the network entity 105-a may send the JCS waveform 230 and perform sensing periodically, for example, according to a configured periodicity. For example, the network entity 105-a may send the JCS waveform 230 according to a sensing period, which may be determined or adjusted based on the environment of the wireless communication system 200. In a relatively fast-changing environment, the network entity 105-a may send the JCS waveform 230 more frequently to maintain awareness of the environment. In other examples, the network entity 105-a may use the JCS waveform 230 to perform sensing in a dynamic manner, such as when tracking a target of interest.

[0131] To support successful reception of the JCS waveform 230, the network entity 105-a may send a message 220 to inform the UE 115-a of one or more parameters for the configuration of the JCS waveform 230 so that the UE 115-a can demodulate and decode the JCS waveform 230 according to the modulation scheme applied by the network entity 105-a. Figure 3 Described in more detail, the network entity 105-a may indicate in message 220 a first modulation scheme, a second modulation scheme, and an RE pattern associated with the transport block. The RE pattern may indicate which REs are associated with the first set of REs and are therefore modulated according to the first modulation scheme. In some examples, the UE 115-a may assume that any REs not included in the RE pattern belong to the second set of REs and are modulated according to the second modulation scheme. The UE 115-a may demodulate a first portion of data mapped to the first set of REs according to the RE pattern based on the first modulation scheme, and may demodulate a second portion of data mapped to the second set of REs based on the second modulation scheme.

[0132] In some cases, the network entity 105-a may transmit the JCS waveform 230 according to the power allocation. The network entity 105-a may transmit the first portion of the data on the first set of REs according to the first transmit power, and may transmit the second portion of the data on the second set of REs according to the second transmit power. To achieve adequate sensing performance, the network entity 105-a may boost the transmit power of the first set of REs compared to the second set of REs, e.g., the first transmit power may be greater than the second transmit power. The network entity 105-a may indicate the first transmit power, the second transmit power, or both in the message 220.

[0133] In some cases, the network entity 105-a may semi-statically configure (e.g., pre-configure) the JCS waveform 230 via a message 220, which may be an example of an RRC message. The message 220 may indicate a configuration, which may include a first modulation scheme, a second modulation scheme, a first transmit power, a second transmit power, an RE pattern for a first set of REs, or a combination thereof. The network entity 105-a may send the message 220 to configure multiple transmissions of the JCS waveform 230, which may be sent by the network entity 105-a at regular intervals (e.g., periodically). The message 220 may additionally indicate a periodicity of the configuration, which may correspond to a periodicity for sending the JCS waveform 230. Thus, the network entity 105-a and the UE 115-a may periodically apply the configuration indicated by the message 220, which may enable the UE 115-a to receive a periodic JCS waveform 230 without receiving configuration information for each JCS waveform 230. For example, the message 220 may indicate a periodicity such that the UE 115-a assumes that transmissions received from the network entity 105-a are JCS waveforms 230 according to the periodicity and may receive these transmissions according to this configuration.

[0134] Additionally or alternatively, the message 220 may indicate a duration of time over which the indicated configuration is to be applied. During the duration of time, the configuration may be considered active, e.g., it may be assumed that the transmission communicated within the duration of time is a JCS waveform 230, and the UE 115-b may receive the JCS waveform 230 according to the configuration. After the duration of time, the configuration may be considered inactive, and the UE 115-a may avoid applying the configuration. For example, the message 220 may indicate the number of time domain resources (e.g., time slots, symbols, etc.) on which the configuration is to be applied for each periodic instance of the JCS waveform 230. In this example, the network entity 105-a may send the JCS waveform such that the first set of REs and the second set of REs span the number of time domain resources, and the UE 115-b may apply the configuration for the number of time domain resources. In another example, the message 220 may indicate the duration of time by indicating an end time or system frame number (SFN), after which the configuration is inactive. Additionally or alternatively, the message 220 may indicate a timer, such that expiration of the timer indicates that the configuration should no longer be applied (eg, the configuration is inactive after expiration of the timer).

[0135] In some examples, the network entity 105-a may send one or more additional messages 220 to activate, deactivate, or modify the configuration for the JCS waveform 230. For example, the network entity 105-a may semi-statically configure the configuration to the UE 115-b via the message 220, but the UE 115-a may not apply the configuration until the network entity 105-a sends a second message 220 indicating the activation of the configuration. The second message 220 may be an example of dynamic control signaling such as DCI, SCI, etc., which includes a field (e.g., a one-bit field) for indicating that the configuration is active. In some cases, the second message 220 may indicate the activation of the configuration for an upcoming transmission (such as a transmission scheduled by the second message 220) (e.g., may indicate that the upcoming transmission is a JCS waveform 230). For another example, the network entity 105-a may send one or more JCS waveforms 230 according to the configuration until the network entity 105-a sends a second message 220 indicating that the configuration is inactive (e.g., terminated). Additionally or alternatively, the network entity 105 - a may determine to update (eg, modify) one or more parameters of the configuration and may send the second message 220 to indicate the updated one or more parameters.

[0136] In some cases, the network entity 105-a may semi-statically configure a first subset of the configured parameters and may dynamically configure a second subset of the configured parameters. The network entity 105-a may send a message 220 (which may be an example of RRC signaling) to indicate the first subset of parameters and may send a second message 220 (which may be an example of a DCI, an SCI, a MAC control element (MAC-CE), etc.) to indicate the second subset of parameters. For example, the first subset of parameters indicated by the message 220 may include a set of modulation schemes for sensing, and the network entity 105-a may indicate, via the second message 220, a modulation scheme from the set of modulation schemes to be used for a subsequent JCS waveform 230.

[0137] Alternatively, the network entity 105-a may dynamically indicate one or more parameters for configuration of the JCS waveform 230. Here, the message 220 may be an example of a DCI, an SCI, a MAC-CE, etc. The network entity 105-a may send a message 220 indicating one or more parameters of each JCS waveform 230 sent by the network entity 105-a. For example, the network entity 105-a may send a message 220 including a DCI scheduling a JCS waveform 230, wherein the DCI indicates one or more parameters to be used by the UE 115-a to receive the scheduled JCS waveform 230. In such an example, the message 220 may indicate a table (e.g., a pre-configured table) corresponding to the one or more parameters. For example, each entry in the table may correspond to a configured parameter, wherein the value of the entry may be mapped to the value of the corresponding parameter.

[0138] In some cases, the network entity 105-a may send a message 220 to indicate the network entity 105-a's intent to apply a configuration (e.g., a JCS configuration) to subsequent transmissions from the network entity 105-a. The network entity 105-a and the UE 115-a may coordinate to determine parameters for the configuration, for example, based on capability information associated with the network entity 105-a, the UE 115-a, or both. For example, as part of the message 220, the network entity 105-a may indicate capability information associated with the network entity 105-a for the configuration, such as one or more parameters supported by the network entity 105-a. The UE 115-a may send a message 225 in response to the message 220 indicating capability information associated with the UE 115-a, such as whether the UE 115-a supports the JCS waveform or the indicated configuration. The message 225 may be an example of control signaling, such as RRC signaling, or may include a feedback message (e.g., a HARQ feedback message) or may be an example of a feedback message.

[0139] For example, UE 115-a may indicate the ability of UE 115-a to receive JCS waveforms, and may further indicate support for the configuration indicated by network entity 105-a. In this example, network entity 105-a may send JCS waveform 230 according to the indicated configuration. Alternatively, UE 115-a may indicate that UE 115-a has the ability to receive JCS waveform 230, but does not support the configuration indicated by network entity 105-a. In either case, UE 115-a may include capability information associated with a set of parameters for the configuration in message 225. For example, UE 115-a may indicate a set of parameters for the configuration supported by UE 115-a. In another example, UE 115-a may indicate a preference of UE 115-a for the configuration, such as one or more preferred parameters. Here, UE 115-a may select preferred parameters based on, for example, a tradeoff associated with one or more parameters indicated by network entity 105-a in message 220.

[0140] For example, UE 115-a may determine that the modulation scheme for sensing indicated in message 220 is associated with a relatively low data rate. UE 115-a may be unwilling or unable to sacrifice data rate performance to support a sensing process to be performed at network entity 105-a, and may select a different modulation scheme for sensing that may be associated with a higher data rate (e.g., from a set of modulation schemes). UE 115-a may indicate the selected modulation scheme as part of the preferred parameters indicated in message 225. Other preferred parameters may include an RE pattern for the first set of REs, a transmit power for the first set of REs, a transmit power for the second set of REs, a power allocation between the first set of REs and the second set of REs, or a combination thereof.

[0141] When sending the JCS waveform 230, the network entity 105-a may consider the message 225 received from the UE 115-a. For example, the network entity 105-a may select parameters for configuration of the JCS waveform 230 that align with the capability information indicated by the UE 115-a (e.g., supported by the UE 115-a) to ensure that the UE 115-a is able to receive the JCS waveform 230. If the UE 115-a indicates a preferred set of parameters, the network entity 105-a may send the JCS waveform 230 according to one or more parameters in the preferred set of parameters. However, if the UE 115-a indicates that the UE 115-a is not capable of supporting the JCS waveform, the network entity 105-a may refrain from sending the JCS waveform 230 to the UE 115-a.

[0142] The preferences of the UE 115-a may change over time, and in some cases, the UE 115-a may request reconfiguration of the JCS waveform 230, e.g., via transmission of the second message 225. For example, the UE 115-a may request the network entity 105-a to switch to a different modulation scheme for a subsequent JCS waveform 230, such as a modulation scheme associated with a relatively higher data throughput than a currently configured modulation scheme. In another example, the UE 115-a may no longer support power boosting of a first set of REs (e.g., associated with sensing), and may request the network entity 105-a to modify the first transmit power, the second transmit power, or both. For example, the UE 115-a may request the network entity 105-a to apply the same transmit power to both the first set of REs and the second set of REs, or to request the network entity 105-a to reduce the first transmit power.

[0143] In any case, the UE 115-a may identify or otherwise select one or more parameters (e.g., preferred parameters) for configuration of the JCS waveform 230 to be updated by the network entity 105-a. The UE 115-a may indicate the one or more preferred parameters via control signaling, such as RRC signaling, or via feedback information, such as a feedback message. In the latter example, the UE 115-a may send feedback for the JCS waveform 230 and may include the one or more preferred parameters in the feedback message. For example, the UE 115-a may send a NACK sequence or an ACK sequence including information associated with the one or more preferred parameters.

[0144] The network entity 105-a may update one or more parameters for the configuration of the JCS waveform 230 based on the one or more preferred parameters indicated by the UE 115-a. In some examples, the network entity 105-a may send a message (e.g., a control signal) to the UE 115-a to indicate the updated parameters. The network entity 105-a may send a subsequent JCS waveform 230 to the UE 115-a according to the updated parameters.

[0145] In some examples, the network entity 105-a may send the JCS waveform 230 based on a quality of service (QoS) associated with the communication link 215 (e.g., communication link 215-a, communication link 215-b) between the UE 115-a and the network entity 105-a. For example, the communication link 215 may be associated with one or more QoS parameters (e.g., QoS requirements) such as a QoS flow identifier (QFI), a priority field value (e.g., indicated via an SCI), etc. The network entity 105-a may determine whether to send the JCS waveform 230 according to the configuration based on the one or more QoS parameters. As an example, if the communication link 215 is associated with a relatively high throughput QoS requirement, for example, if sending the JCS waveform 230 according to the first modulation scheme and the second modulation scheme may not meet the throughput QoS requirement, the network entity 105-a may avoid sending the JCS waveform 230. Additionally or alternatively, the network entity 105-a may select one or more parameters for the configuration of the JCS waveform 230 based on the one or more QoS parameters. For example, the network entity 105 - a may select an RE pattern having a relatively low number of REs for the first set of REs, or select a modulation scheme from a set of modulation schemes to avoid significant throughput degradation associated with the first set of REs.

[0146] Figure 3An example of a resource allocation configuration 300 that supports constellation-based resource allocation for sensing and communication according to one or more aspects of the present disclosure is illustrated. The resource allocation configuration 300 may be implemented by the wireless communication systems 100 and 200, or may implement aspects of these wireless communication systems. For example, as shown in FIG. Figure 1 and Figure 2 As described, UE 115 or network entity 105 may implement aspects of resource allocation configuration 300 to transmit a JCS waveform according to the techniques described herein.

[0147] Resource allocation configuration 300 may be an example of a configuration for a JCS waveform. As described herein, a transmitting device (e.g., a UE, a network entity) may configure a JCS waveform based on one or more waveform parameters. The JCS waveform may be transmitted over a set of REs (e.g., time and frequency resources) (e.g., a set of symbols and a set of subcarriers, respectively) via a communication link (e.g., PDSCH, PUSCH, PSSCH). According to the techniques described herein, a transmitting device may allocate data of a transport block 305 to REs of a JCS waveform based on a modulation scheme associated with the JCS waveform. In other words, the transmitting device may allocate modulated symbols of a transport block 305 to REs based on the constellation from which the modulation symbols originate.

[0148] As reference Figure 2 As described, one or more waveform parameters may include at least a first modulation scheme, a second modulation scheme, and an RE pattern. The first modulation scheme may be an example of a 16-QAM scheme, and may correspond to constellation 320-a (e.g., represented by the constellation). The second modulation scheme may be an example of a QPSK scheme, and may correspond to constellation 320-b (e.g., represented by the constellation). The RE pattern may be an example of an interlaced comb 3 pattern. A first subset of REs in a set of REs may be associated with data (e.g., and not with sensing) and may be referred to as data REs 310. A second subset of REs in a set of REs may be associated with sensing and may be referred to as sensing REs 315. As shown, the RE pattern may be used for sensing REs 315, so that the sensing REs 315 are distributed over a set of REs according to an interlaced comb 3 pattern.

[0149] The transmitting device may modulate the first portion of the data of the transport block 305 according to the first modulation scheme. The transmitting device may map the first portion of the data to the data REs 310 based on the first modulation scheme such that the data-carrying symbols of the data REs 310 originate from the constellation 320-a. For example, the transmitting device may assign modulation symbols from the constellation 320-a to the data REs 310 of the transport block 305 according to the RE pattern.

[0150] The transmitting device may modulate the second portion of the data of the transport block 305 according to the second modulation scheme, and may map the second portion of the data to the sensing RE 315 based on the second modulation scheme. Therefore, the transmitting device may obtain the data-bearing symbols to be allocated to the sensing RE 315 from the constellation 320-b. That is, the transmitting device may allocate the modulation symbols from the constellation 320-b to the sensing RE 315 of the transport block 305 according to the RE pattern.

[0151] The transmitting device may transmit the transport block 305 via the JCS waveform based on the allocation of the data RE 310 and the sensing RE 315 and according to one or more waveform parameters. The receiving device may receive the transport block 305 and may demodulate the first part of the data and the second part of the data according to the first modulation scheme and the second modulation scheme, respectively. For example, the receiving device may demodulate the data transmitted on the data RE 310 based on the first demodulation scheme. The receiving device may demodulate the data transmitted on the sensing RE 315 based on the second demodulation scheme.

[0152] Additionally, the transmitting device may perform sensing using the sensing RE 315. For example, the transmitting device may monitor the reflection of the JCS waveform transmitted via the sensing RE 315. In some cases, the transmitting device may perform one or more measurements on the sensing RE 315 to obtain a channel estimate for the communication link over which the JCS waveform is transmitted. The transmitting device may calculate or otherwise identify a channel frequency response via the sensing RE 315, and may obtain a CIR based on the channel frequency response.

[0153] The RE pattern may be associated with a density of sensing REs 315 corresponding to the number of sensing REs 315. The number of sensing REs 315 in the frequency domain may correspond to the frequency density for sensing, and the number of sensing REs 315 in the time domain may correspond to the time density for sensing. The time density and frequency density indicated by the RE pattern may affect channel estimation or other calculations performed by the transmitting device. A relatively high number of sensing REs 315 corresponding to a relatively high density of sensing REs 315 may be associated with an improved sensing process. For example, an RE pattern associated with a relatively high density of sensing REs 315 in the time domain, the frequency domain, or both may enable the transmitting device to obtain channel measurements from a larger number of sensing REs 315, which may provide improved sensing resolution and accuracy.

[0154] In some examples, the RE pattern may overlap with another RE pattern such as a reference signal (e.g., a demodulation reference signal (DMRS), a phase tracking (PT) reference signal (PT RS)) RE pattern. Figure 3The sensing RE 315 associated with the illustrated RE pattern may overlap with the RE associated with the DMRS RE pattern. In such an example, the transmitting device may yield the RE to the DMRS RE pattern. That is, the transmitting device may avoid mapping the second portion of the data (e.g., data from constellation 320-b) to the sensing RE 315, and may instead transmit the DMRS on the sensing RE 315. In such a case, the transmitting device may include the DMRS as part of the sensing process, for example, sensing may be performed based on the DMRS and other (non-overlapping) sensing REs 315.

[0155] Figure 4 An example of a process flow 400 for supporting constellation-based resource allocation for sensing and communication according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 400 can implement aspects of the wireless communication systems 100 and 200 and the resource allocation configuration 300. For example, the process flow 400 includes a UE 115-b and a network entity 105-b, which can be examples of corresponding devices described herein. The network entity 105-b can send a transport block via a JCS waveform, and the UE 115-b can receive a transport block via a JCS waveform, wherein the JCS waveform can implement aspects of the resource allocation configuration 300.

[0156] In the following description of process flow 400, the operations between UE 115-b and network entity 105-b may be sent in an order different from the order shown, or the operations may be performed at different times. Some operations may also be excluded from process flow 400, or other operations may be added to process flow 400. Although UE 115-b and network entity 105-b are shown as performing the operations of process flow 400, any wireless device or any number of devices may perform the operations shown.

[0157] At 405, the network entity 105-b may select one or more waveform parameters of the JCS waveform. That is, the network entity 105-b may determine a configuration for the JCS waveform (e.g., a JCS waveform configuration), the configuration including one or more waveform parameters for transmitting the JCS waveform. The one or more waveform parameters may include a number of time domain resources for the configuration, a periodicity of the configuration, a time duration for which the configuration is to be used, a system frame number corresponding to an end time of the configuration, or a combination thereof, among other examples.

[0158] Additionally, the network entity 105-b may select or otherwise determine one or more waveform parameters for a first set of REs associated with the transport block, one or more waveform parameters for a second set of REs associated with the transport block, or a combination thereof. The first set of REs may be associated with sensing, and the second set of REs may be associated with data communication. The one or more waveform parameters for the first set of REs may include, but are not limited to, a RE pattern, a first modulation scheme, and a first transmit power. The network entity 105-b may select a first modulation scheme associated with sensing from a set of modulation schemes; the set of modulation schemes may include at least one of PSK, QPSK, and a constant modulus modulation scheme. The one or more waveform parameters for the second set of REs may include, but are not limited to, a second modulation scheme (e.g., different from the first modulation scheme) and a second transmit power (e.g., different from the first transmit power). The second modulation scheme may be used for data communication and may be an example of a higher order modulation scheme such as QAM.

[0159] In some examples, network entity 105-b may select or otherwise determine one or more waveform parameters based on a QoS associated with a communication link between network entity 105-b and UE 115-b. For example, network entity 105-b may determine or identify one or more QoS values ​​associated with the communication link and may select one or more waveform parameters corresponding to the one or more QoS values. In some cases, network entity 105-b may receive control signaling indicating a mapping between one or more QoS values ​​and one or more waveform parameters and may select one or more waveform parameters based on the mapping.

[0160] At 410, the network entity 105-b may optionally send, and the UE 115-b may receive, at least one message indicating a configuration, one or more waveform parameters, or a combination thereof. For example, the network entity 105-b may send a signal (e.g., a control signal) indicating that a transport block is to be sent according to a configuration (e.g., a JCS waveform configuration) and indicating one or more parameters (e.g., waveform parameters) for the configuration supported by the network entity 105-b. In some cases, the indicated one or more parameters may include the one or more waveform parameters selected at 405.

[0161] Additionally or alternatively, network entity 105-b may send at least one message indicating the one or more waveform parameters selected at 405. In some cases, as part of the at least one message, network entity 105-b may send an indication of a table corresponding to the one or more waveform parameters selected at 405. In some examples, the at least one message may include control signaling (such as RRC signaling, DCI, SCI, MAC-CE, or a combination thereof) or may be an example of control signaling. For example, network entity 105-b may send a first message indicating a first subset of one or more parameters, wherein the first message is an RRC message. Network entity 105-b may send a second message indicating a second subset of one or more parameters, wherein the second message is a DCI, SCI, or MAC-CE.

[0162] At 415, UE 115-b may optionally send, and network entity 105-b may receive, a message indicating whether UE 115-b supports the configuration, one or more parameters, or both. The message may include control signaling (e.g., RRC signaling) or a feedback message (e.g., a HARQ feedback message, such as an ACK or a NACK) or may be an example of either. For example, UE 115-b may indicate that UE 115-b supports the configuration (e.g., indicated at 410) and supports one or more parameters (e.g., indicated at 410). Alternatively, UE 115-b may indicate that UE 115-b supports the configuration and may indicate a set of parameters for the configuration supported by UE 115-b, which set of parameters may be different from the one or more parameters indicated by network entity 105-b at 410. The set of parameters may include a first modulation scheme for a first set of REs, a second modulation scheme for a second set of REs, a transmit power for a first set of REs, a transmit power for a second set of REs, an RE pattern for a first set of REs, a number of time domain resources for configuration, a periodicity of configuration, or a combination thereof.

[0163] Additionally or alternatively, UE 115-b may send a message indicating one or more preferences of UE 115-b for a JCS waveform (e.g., for a configuration). For example, UE 115-b may indicate one or more waveform parameters preferred by UE 115-b, such as a first modulation scheme for a first set of REs, a second modulation scheme for a second set of REs, a transmit power for a first set of REs, a transmit power for a second set of REs, a pattern of REs for a first set of REs, a number of time domain resources for configuration, a periodicity of configuration, or a combination thereof.

[0164] In some cases, network entity 105-b may select, adjust, or modify one or more waveform parameters for configuration of the JCS waveform based on receiving the message at 415. For example, network entity 105-b may select one or more waveform parameters supported by UE 115-b, e.g., as indicated by the message received at 415. As another example, network entity 105-b may have previously selected one or more waveform parameters (e.g., at 405), but may adjust (e.g., update) at least one of the one or more waveform parameters based on the message received at 415, e.g., according to a set of parameters supported or preferred by UE 115-b. Here, network entity 105-b may send a signal to UE 115-b indicating the adjusted at least one waveform parameter.

[0165] At 420, the network entity 105-b may modulate portions of the data of the transport block. The network entity 105-b may modulate a first portion of the data according to a first modulation scheme (e.g., from a set of modulation schemes used for sensing). Additionally, the network entity 105-b may modulate a second portion of the data according to a second modulation scheme.

[0166] At 425, the network entity 105-b may map portions of the data of the transport block to a first set of REs and a second set of REs. The network entity 105-b may map the first portion of the modulated data to the first set of REs based on a first modulation scheme, and the first set of REs is used for sensing. In some cases, the network entity 105-b may map the first portion of the modulated data to the first set of REs according to a RE pattern for the first set of REs. The network entity 105-b may map the second portion of the data to the second set of REs based on a second modulation scheme, and the second set of REs is associated with data communication.

[0167] In some examples, network entity 105-b may determine that at least one RE in the first set of REs is associated with (e.g., reserved for) a reference signal RE used to send a reference signal such as a DMRS, a PT reference signal, etc. For example, the at least one RE may overlap with a reference signal RE associated with the reference signal RE pattern. In such a case, network entity 105-b may avoid mapping the first portion of the modulated data to the at least one RE.

[0168] At 430, on a communication link between the network entity 105-b and the UE 115-b, the network entity 105-b may send, via a JCS waveform, and the UE 115-b may receive, via the JCS waveform, a transport block including a first portion of the mapped data and a second portion of the mapped data. For example, based on one or more waveform parameters and a configuration for the JCS waveform, the network entity 105-b may send, via the JCS waveform, and the UE 115-b may receive, the transport block via the JCS waveform. For example, the network entity 105-b may send the first portion of the data according to a first transmit power, and may send the second portion of the data according to a second transmit power. Additionally or alternatively, based on one or more QoS values ​​for the communication link, a mapping between the QoS value and one or more waveform parameters, or a combination thereof, the network entity 105-b may send, and the UE 115-b may receive, the transport block.

[0169] In some cases, based on a set of parameters supported by UE 115-b or one or more preferences of UE 115-b (e.g., based on the message received at 415), network entity 105-b may send via a JCS waveform and UE 115-b may receive a transport block via a JCS waveform.

[0170] At 435, UE 115-b may demodulate the first portion of the data and the second portion of the data based on at least the first modulation scheme. For example, UE 115-b may demodulate the first portion of the data according to the first modulation scheme and may demodulate the second portion of the data according to the second modulation scheme.

[0171] At 440, the network entity 105-b may optionally use the first set of REs to perform a sensing process. For example, the network entity 105-b may perform channel estimation for the communication link based on the JCS waveform. Additionally or alternatively, the network entity 105-b monitors reflections of the JCS waveform (e.g., sent at 430). Based on the received reflections of the JCS waveform, the network entity 105-b may obtain or otherwise calculate parameters (e.g., distance, speed, etc.) associated with one or more target objects from which the JCS waveform was reflected. In some cases, if at least one RE in the first set of REs overlaps with a reference signal RE, the network entity 105-b may perform a sensing process using the first set of REs and a reference signal associated with the reference signal RE.

[0172] Figure 5A block diagram 500 of a device 505 supporting constellation-based resource allocation for sensing and communication according to one or more aspects of the present disclosure is shown. The device 505 may be an example of aspects of a UE 115 or a network entity 105 as described herein. The device 505 may include a receiver 510, a transmitter 515, and a communication manager 520. The device 505 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0173] The receiver 510 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 related to constellation-based resource allocation for sensing and communication). The information may be communicated to other components of the device 505. The receiver 510 may utilize a single antenna or a collection of multiple antennas.

[0174] The transmitter 515 may provide means for transmitting signals generated by other components of the device 505. For example, the transmitter 515 may transmit 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 related to constellation-based resource allocation for sensing and communication). In some examples, the transmitter 515 may be co-located with the receiver 510 in a transceiver module. The transmitter 515 may utilize a single antenna or a collection of multiple antennas.

[0175] The communication manager 520, the receiver 510, the transmitter 515, or various combinations thereof, or various components thereof, may be examples of means for performing various aspects of constellation-based resource allocation for sensing and communication as described herein. For example, the communication manager 520, the receiver 510, the transmitter 515, or various combinations thereof, or components thereof, may support methods for performing one or more of the functions described herein.

[0176] In some examples, the communication manager 520, the receiver 510, the transmitter 515, 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).

[0177] Additionally or alternatively, in some examples, the communication manager 520, the receiver 510, the transmitter 515, or various combinations or components thereof may be implemented in code executed by a processor (e.g., as communication management software or firmware). If implemented in code executed by a processor, the functionality of the communication manager 520, the receiver 510, the transmitter 515, or various combinations or components thereof may be performed by a general purpose processor (e.g., configured as or otherwise supporting components for performing the functions described in the present disclosure), a DSP, a CPU, an ASIC, an FPGA, a microcontroller, or any combination of these or other programmable logic devices.

[0178] In some examples, communication manager 520 may be configured to perform various operations (e.g., receive, obtain, monitor, output, send) using or otherwise cooperating with receiver 510, transmitter 515, or both. For example, communication manager 520 may receive information from receiver 510, transmit information to transmitter 515, or be integrated in conjunction with receiver 510, transmitter 515, or both to obtain information, output information, or perform various other operations as described herein.

[0179] According to examples as disclosed herein, the communication manager 520 may support wireless communications at a wireless device. For example, the communication manager 520 may be configured to or otherwise support a component for modulating a first portion of data of a transport block associated with a JCS waveform according to a modulation scheme for sensing.
