Description

WIRELESS SENSING INDICATION IN NEW RADIO COMMUNICATIONS

FIELD OF TECHNOLOGY

The following relates generally to wireless communications and more specifically to wireless sensing indication in new radio communications.

BACKGROUND

Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the 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, LTE-Advanced (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 technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal frequency division multiple access (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE) .

A UE or a base station may perform wireless detection sensing using a same bandwidth as wireless communications. Sharing the bandwidth for both wireless detection sensing signals and wireless communications signals may result in collisions between the signals. Some techniques for sharing the bandwidth with both types of signaling can be improved.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support wireless sensing indication in new radio communications. Generally, the described techniques provide for sharing a radio frequency spectrum band between sensing signals and wireless communications signals. A wireless detection sensing signal may be transmitted using a bandwidth which is also used for wireless communications. Wireless communications and wireless detection sensing signaling sharing the same bandwidth may lead to collisions between the signals. The techniques described herein support efficient dynamic resource sharing of wireless detection sensing signaling and wireless communications. For example, by indicating which resources are reserved for wireless detection sensing, a device may efficiently use resources around the reserved resources for wireless communications. Additionally, or alternatively, a device may either cancel transmissions which are scheduled to overlap with the reserved resources or empty a buffer of received information corresponding to the reserved resources. These techniques may prevent collisions between the wireless detection sensing and the wireless communications. In some cases, there may be configured wireless detection sensing occasions on the radio frequency spectrum band. The device may be indicated which of the configured wireless detection sensing occasions are reserved and used for wireless detection sensing, and which of the configured wireless detection sensing occasions are not being used for wireless sensing. The device may then accordingly communicate around the reserved wireless sensing occasions.

DETAILED DESCRIPTION

Some devices in a wireless communications system may use wireless sensing for precise environment imaging. For example, a user equipment (UE) in a vehicle-to-everything (V2X) system may use wireless sensing to detect locations or movements of vehicles, obstructions, pedestrians, etc. Wireless detection sensing may be used for other environment sensing as well, such as building analytics and digital health monitoring. A wireless sensing signal may be transmitted using a millimeter wave, which may provide a high level of detail for extracting range, velocity, or angular information for the environment imaging. Some wireless communications systems may use sub-6 Gigahertz radio frequency spectrum bands and millimeter wave radio frequency spectrum bands for wireless communications. Therefore, some systems may support both wireless communications and wireless sensing on a millimeter wave radio frequency spectrum band. Wireless communications and wireless sensing sharing the same bandwidth may lead to collisions between the signals. Furthermore, it may be inefficient to allocate dedicated resources for wireless sensing and wireless communication separately.

The techniques described herein support efficient dynamic resource sharing of wireless sensing and wireless communications. These techniques support dynamic indication of resources which are allocated, or reserved, for wireless sensing in a radio frequency spectrum band that may also be used for wireless communications. By indicating which resources are reserved for wireless sensing, a device may efficiently use resources around the reserved resources for wireless communications. Additionally, or alternatively, the device may either cancel transmissions which are scheduled to overlap with the reserved resources or empty a buffer of received information corresponding to the reserved resources. These techniques may prevent collisions between the wireless sensing and the wireless communications. In some cases, there may be configured wireless sensing occasions on the radio frequency spectrum band. The device may be indicated which of the configured wireless sensing occasions are reserved and used for wireless sensing, and which of the configured wireless sensing occasions are not being used for wireless sensing. The device may then accordingly communicate around the reserved wireless sensing occasions. These techniques may be implemented for communications between a base station and a UE, between UEs (e.g., in device-to-device (D2D) communications or sidelink communications) , V2X communications, or others.

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to wireless sensing indication in new radio communications.

FIG. 1 illustrates an example of a wireless communications system 100 that supports wireless sensing indication in new radio communications in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communications system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

The base stations 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may be devices in different forms or having different capabilities. The base stations 105 and the UEs 115 may wirelessly communicate via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base station 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a base station 105 and a UE 115 may support the communication of signals according to one or more radio access technologies.

The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115, the base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment) , as shown in FIG. 1.

The base stations 105 may communicate with the core network 130, or with one another, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface) . The base stations 105 may communicate with one another over the backhaul links 120 (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between base stations 105) , or indirectly (e.g., via core network 130) , or both. In some examples, the backhaul links 120 may be or include one or more wireless links.

One or more of the base stations 105 described herein may include or may be referred to by a person having ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a Home NodeB, a Home eNodeB, or other suitable terminology.

A 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 the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A 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, a UE 115 may include or 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 communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.

The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the base stations 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.

The UEs 115 and the base stations 105 may wirelessly communicate with one another via one or more communication links 125 over one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP) ) that is operated 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 that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers.

In some examples (e.g., in a carrier aggregation configuration) , a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN) ) and may be positioned according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode where initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode where a connection is anchored using a different carrier (e.g., of the same or a different radio access technology) .

The communication links 125 shown in the wireless communications system 100 may include uplink transmissions from a UE 115 to a base station 105, or downlink transmissions from a base station 105 to a UE 115. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .

A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a number of determined bandwidths for carriers of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the base stations 105, the UEs 115, or both) may have hardware configurations that support communications over a particular carrier bandwidth or may be configurable to support communications over one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include base stations 105 or UEs 115 that support simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating over portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.

Signal waveforms transmitted over a carrier may be made up 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, a resource element may consist of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) . Thus, the more resource elements that a UE 115 receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE 115. A wireless communications resource may refer to a combination of a radio frequency spectrum resource, a time resource, and a spatial resource (e.g., spatial layers or beams) , and the use of multiple spatial layers may further increase the data rate or data integrity for communications with a UE 115.

One or more numerologies for a carrier may be supported, where a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.

The time intervals for the base stations 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of T _s = 1/ (Δf _max·N _f) seconds, where Δf _max may represent the maximum supported subcarrier spacing, and N _f may represent the maximum supported discrete Fourier transform (DFT) size. Time intervals of a communications resource 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) .

Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on subcarrier spacing. Each slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems 100, a slot may further be divided into multiple mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N _f) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.

A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications 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 communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .

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

Each base station 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a base station 105 (e.g., over a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) , or others) . In some examples, a cell may also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the base station 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with geographic coverage areas 110, among other examples.

A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a lower-powered base station 105, as compared with a macro cell, and a small cell may operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG) , the UEs 115 associated with users in a home or office) . A base station 105 may support one or multiple cells and may also support communications over the one or more cells using one or multiple component carriers.

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 for different types of devices.

In some examples, a base station 105 may be movable and therefore provide communication coverage for a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, the overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

The wireless communications system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timings, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timings, and transmissions from different base stations 105 may, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operations.

Some UEs 115, such as MTC or IoT devices, may be low cost or low complexity devices and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication) . M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that makes use of the information or presents the information to humans interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception simultaneously) . In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 include entering a power saving deep sleep mode when not engaging in active communications, operating over a limited bandwidth (e.g., according to narrowband communications) , or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs) ) within a carrier, within a guard-band of a carrier, or outside of a carrier.

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

In some examples, a UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol) . One or more UEs 115 utilizing D2D communications may be within the geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of a base station 105 or be otherwise unable to receive transmissions from a base station 105. In some examples, groups of the UEs 115 communicating via D2D communications may utilize a one-to-many (1: M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, a base station 105 facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out between the UEs 115 without the involvement of a base station 105.

In some systems, the D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs 115) . In some examples, vehicles may communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., base stations 105) using vehicle-to-network (V2N) communications, or with both.

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 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (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 the UEs 115 served by the base stations 105 associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to the network operators IP services 150. The operators IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.

Some of the network devices, such as a base station 105, may include subcomponents such as an access network entity 140, which may be an example of an access node controller (ANC) . Each access network entity 140 may communicate with the UEs 115 through one or more other access network transmission entities 145, which may be referred to as radio heads, smart radio heads, or transmission/reception points (TRPs) . Each access network transmission entity 145 may include one or more antenna panels. In some configurations, various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a base station 105) .

The wireless communications system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. The UHF waves may be blocked or redirected by buildings and environmental features, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. The transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmission using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

The wireless communications system 100 may also operate in a super high frequency (SHF) region using frequency bands from 3 GHz to 30 GHz, also known as the centimeter band, or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) , also known as the millimeter band. In some examples, the wireless communications system 100 may support millimeter wave (mmW) communications between the UEs 115 and the base stations 105, and EHF antennas of the respective devices may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate use of antenna arrays within a device. The propagation of EHF transmissions, however, may be subject to even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions that use one or more different frequency regions, and designated use of bands across these frequency regions may differ by country or regulating body.

The wireless communications system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as the base stations 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations in unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating in a licensed band (e.g., LAA) . Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

A base station 105 or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a base station 105 may be located in diverse geographic locations. A base station 105 may have an antenna array with a number of rows and columns of antenna ports that the base station 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel may support radio frequency beamforming for a signal transmitted via an antenna port.

The base stations 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase the spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the 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 bits 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 used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , where multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , where multiple spatial layers are transmitted to multiple devices.

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 base station 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 the signals communicated via antenna elements of an antenna array such that some signals propagating at particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .

A base station 105 or a UE 115 may use beam sweeping techniques as part of beam forming operations. For example, a base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a base station 105 multiple times in different directions. For example, the base station 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device, such as a base station 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the base station 105.

Some signals, such as data signals associated with a particular receiving device, may be transmitted by a base station 105 in a single beam direction (e.g., a direction associated with the receiving device, such as a UE 115) . In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted in one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the base station 105 in different directions and may report to the base station 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.

In some examples, transmissions by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from a base station 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across a system bandwidth or one or more sub-bands. The base station 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The 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 type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted in one or more directions by a base station 105, a UE 115 may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal in a single direction (e.g., for transmitting data to a receiving device) .

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

The wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. A Radio Link Control (RLC) layer may perform packet segmentation and reassembly to communicate over logical channels. A Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a base station 105 or a core network 130 supporting radio bearers for user plane data. At the physical layer, transport channels may be mapped to physical channels.

The UEs 115 and the base stations 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly over a communication link 125. 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 in poor radio conditions (e.g., low signal-to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, where the device may provide HARQ feedback in a specific slot for data received in a previous symbol in the slot. In other cases, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.

The wireless communications system 100 may support wireless sensing. Wireless sensing may be used for environment imaging, such as in a V2X system. For example, a UE 115 may transmit a wireless sensing signal and detect a reflected wireless sensing signal, which may be similar to radar sensing. The reflected wireless sensing signal may indicate information for an object which reflected the signal, such as the location, angular information, and velocity information of the object. The object could be an obstruction in the road, a vehicle UE, a pedestrian, etc. Wireless sensing may be used for other applications as well. For example, wireless sensing may be used for vehicle sensing by millimeter wave Radar and millimeter wave communication, handheld short-range sensing by UEs 115 such as smartphones or smartwatches or in-car-based control UE sensing, building analytics, such as residential security or building management (e.g., performed by sensing at a base station 105) , digital health monitoring, such as device-free eldercare by motion sensing, and sensing to support wireless communications, among other uses. In some cases, a higher sensing granularity may be supported by, for example, Terahertz radio. In some cases, digital health sensing may be performed by a customer premise equipment (CPE) or an access point.

In some cases, the wireless sensing signal may be transmitted on a bandwidth that is also used for wireless communications in the wireless communications system 100. For example, the wireless sensing signal may be transmitted using a millimeter wave bandwidth. Some wireless communications, such as NR communications, may use both sub-6GHz bands (e.g., Frequency Range 1 (FR1) bands) and millimeter wave bands (e.g., Frequency Range 2 (FR2) bands) for communications. Using a cellular band for wireless sensing may provide some advantages for wireless sensing. For example, a device (e.g., a base station 105 or a UE 115) transmitting the wireless sensing signal may already be configured with radio frequency hardware and antennas which use the radio frequency spectrum band. Additionally, wireless sensing may use some frameworks of wireless communications for efficient sensing procedures, such as re-using a channel state information (CSI) framework as a coarse input for a higher resolution sensing. In some cases, wireless sensing may also provide some information for the wireless communications. For example, the wireless communications system 100 may use environment sensing for network management (e.g., beam adaptation, protocol adaptation, etc. ) based on an environment condition which may be obtained via the wireless sensing.

In some cases, sharing the radio frequency spectrum band between wireless detection sensing and wireless communications may cause collisions between the signaling. Some wireless communications systems may implement techniques such as a preemption indication or a cancellation indication to indicate possible signaling collisions between high priority signaling and lower priority signaling. For example, for urgent transmission of a higher priority UE 115 (e.g., sending ultra-reliable, low latency communications) , some already indicated resource allocation for a lower-priority UE 115 may be preempted by the higher-priority data transmission. For downlink signaling, a preemption indication may be sent after a base station 105 has transmitted the URLLC data to indicate to the lower-priority UE 115 that the signaling in the overlap resources was not targeted for the lower-priority UE 115. For uplink, an a priori cancellation indication may be sent before an uplink transmission (e.g., an uplink shared channel transmission or a sounding reference signal) to configure the lower-priority UE to cancel the uplink transmission.

Wireless detection sensing signaling may be transmitted in bursts of pulses. The pulses may, in some cases, span a large frequency bandwidth (e.g., the system bandwidth) and be transmitted closely together in the time domain. Some current techniques for preempting, or cancelling, resource assignments may not provide sufficient granularity for preempting or cancelling resources which overlap with a wireless detection sensing signal. For example, some current preemption or cancellation techniques for high priority signaling may not be granular enough to support communications in resources which are not directly overlapping the wireless detection sensing signal or between the pulses of a wireless detection sensing signal, or these techniques may not sufficiently indicate the wide bandwidth usage of the wireless detection sensing signal. Therefore, the

wireless communications systems

100 and 200 described herein may implement techniques described herein to indicate wireless sensing with a fine enough granularity to support wireless communications in available resources which do not overlap with the reserved resources. In some examples, some aspects of the techniques for preemption indications and cancellation indications may be implemented to support indicating wireless detection sensing signals for enhanced use of a radio frequency spectrum band for wireless communications.

In some examples, a transmitting device may send a sensing signal occasion indication to other devices to indicate which resources are reserved for the wireless sensing signal. In some cases, there may be a set of possible wireless sensing signal occasions, though a subset of the possible wireless sensing signal occasions may actually be reserved and used for wireless sensing. A pattern for the wireless sensing signal occasions may be preconfigured, and the transmitting device may indicate which of the occasions in a time range are reserved for wireless detection sensing. The transmitting device may send the indication the reserved occasions to neighboring devices, which may also indicate which of the occasions may be used for wireless communications. The indication may indicate reserved an unused occasions within a corresponding time range, such as a number of slots before or after the indication. This may support efficient use of the radio frequency spectrum band, as neighboring devices may use the non-reserved resources for wireless communications.

FIG. 2 illustrates an example of a wireless communications system 200 that supports wireless sensing indication in new radio communications in accordance with aspects of the present disclosure. In some examples, wireless communications system 200 may implement aspects of wireless communication system 100. The wireless communications system 200 may include UE 115-a and base station 105-a, which may be respective examples of a UE 115 and a base station 105 described with reference to FIG. 1. The wireless communications system 200 may include vehicle UE (V-UE) 205-a and V-UE 205-b, which may each be an example of a UE 115. The techniques described herein may be implemented for communication between UEs 115, base stations 105, V-UEs 205, or any combination thereof, among other examples of devices in the

wireless communications system

100 or 200.

The wireless communications system 200 may support wireless sensing. Wireless sensing may be used for environment imaging, such as in a V2X system. For example, V-UE 205-a may transmit a wireless sensing signal 210 and detect a reflected wireless sensing signal 215. The reflected wireless sensing signal 215 may indicate information for an object 220, such as the location, angular information, and velocity information of the object 220. The object 220 could be an obstruction in the road, another V-UE 205 (e.g., V-UE 205-b) , a pedestrian, etc. The wireless sensing signal 210 may be transmitted as a burst of wireless signal pulses, which may be similar to some aspects of radar sensing. Wireless sensing may be used for other applications as well, such as facial or movement recognition at a UE 115, pedestrian movement sensing, short-range sensing in a smartphone or a smartwatch, building analytics or security, digital health monitoring, among other uses.

In some cases, the wireless sensing signal may be transmitted on a bandwidth that is also used for wireless communications in the wireless communications system 200. For example, the wireless sensing signal may be transmitted using a millimeter wave bandwidth. The wireless communications system 200 may also use the millimeter wave bandwidth for wireless communications, such as NR communications in Frequency Range 2. Using a cellular band for wireless sensing may provide some advantages for wireless sensing. For example, a device (e.g., a base station 105, a UE 115, or a V-UE 205) transmitting the wireless sensing signal may already be configured with radio frequency hardware and antennas which use the radio frequency spectrum band. Additionally, wireless sensing may use some frameworks of wireless communications for efficient sensing procedures, such as re-using a channel state information (CSI) framework as a coarse input for a higher resolution sensing. In some cases, wireless sensing may also provide some information for the wireless communications. For example, the wireless communications system 200 may use environment sensing for network management (e.g., beam adaptation, protocol adaptation, etc. ) based on an environment condition which may be obtained via the wireless sensing.

Using the same radio frequency spectrum band for wireless communications and wireless sensing may lead to collisions without specifying resource allocations for the different types of signals. In some cases, dedicated resources for wireless sensing and wireless communications may be inefficient. To support wireless communications and wireless sensing on a same radio frequency spectrum band, the wireless communications system 200 may implement techniques for dynamic resource sharing and wireless sensing indication.

For example, a transmitting device may send a sensing signal occasion indication 225 to other devices to indicate which resources are reserved for the wireless sensing signal. In some cases, there may be a set of possible wireless sensing signal occasions, though a subset of the possible wireless sensing signal occasions may actually be reserved and used for wireless sensing. The transmitting device may send the indication 225 of which occasions are reserved and which may be used for wireless communications. The indication 225 may indicate reserved an unused occasions within a corresponding time range, such as a number of slots before or after the indication 225. This may support efficient use of the radio frequency spectrum band, as neighboring devices may use the non-reserved resources for wireless communications.

In some cases, a time-frequency occupation pattern of the possible wireless sensing signal occasions may be pre-configured or pre-defined. For example, neighboring devices may be configured with the occasions via RRC or system information. Additionally, or alternatively, the pattern for the wireless sensing signal occasions may be included in the sensing signal occasion indication 225. In an example, UE 115-a may be configured with a bitmap, where each bit of the bitmap corresponds to a different wireless sensing signal occasion. If a bit of the bitmap is toggled, it may indicate that the corresponding wireless sensing signal occasion within the time range is reserved for wireless sensing. If the bit is not toggled, it may indicate that the corresponding wireless sensing signal occasion is not used for wireless sensing within the time range and may instead be used for wireless communications. In some cases, UE 115-a may be configured with a set of reserved occasion patterns, and the sensing signal occasion indication 225 may indicate a specific reserved occasion pattern of the set of reserved occasion patterns. For example, each pattern may correspond to a different value, which may save some bits over a bitmap if not all possible combinations of the occasions are used for a reserved pattern.

The sensing signal occasion indication 225 may be transmitted before or after the corresponding wireless sensing signal occasions. For example, the sensing signal occasion indication 225 may correspond to a time range including one or more sensing signal occasions, and the sensing signal occasion indication 225 may be transmitted before the time range (e.g., indicating which of the upcoming occasions are reserved for wireless sensing) or after the time range (e.g., indication which of the occasions were used for wireless sensing) . For example, if the time range occurs before the sensing signal occasion indication 225 is received, the receiving device may be informed that the channels or signals received at the time/frequency resources corresponding to the reserved occasions are not targeted for the receiving device. If the time range occurs after the sensing signal occasion indication 225 is received, the receiving device may cancel transmission of a signal at the time/frequency resources corresponding to the reserved occasions.

For some wireless sensing examples, the wireless sensing signal may be transmitted in a burst using a pulse waveform. For example, the wireless sensing signal 210 may have intervals between the pulses of the burst which may be utilized for wireless communication. In some cases, the receiving device may be configured with the pulse pattern of the wireless sensing signal 210. For example, the transmitting device may indicate the pulse pattern, or the receiving device may be indicated the pulse patterns. Configuring the receiving device with the pulse pattern may enable the receiving device to use any resources between, or adjacent to, the pulse waveform for wireless communications.

The wireless sensing signal 210 may have different waveforms in other examples. For example, in some cases the wireless sensing signal 210 may have a frequency-modulated continuous waveform or a phase-modulated continuous waveform.

These techniques may support efficient use of a radio frequency spectrum band that is used for both wireless communications and wireless sensing. These techniques may prevent collisions between wireless sensing and wireless communications and support high spectral efficiency for wireless communications in the resources which are not reserved for wireless sensing.

FIG. 3 illustrates an example of a wireless sensing burst pattern 300 that supports wireless sensing indication in new radio communications in accordance with aspects of the present disclosure. In some examples, the wireless sensing burst pattern 300 may implement aspects of wireless communication system 100. As described with reference to FIG. 2, a wireless communications system may support wireless sensing and wireless communications on a same radio frequency spectrum band.

A device may transmit a wireless sensing signal 305 on a radio frequency spectrum band. For example, the device may transmit the wireless sensing signal 305 on a millimeter wave band which may also be used for a wireless communications channel 310. In some cases, the wireless sensing signal 305 may be an example of a radar signal which is transmitted over a large bandwidth. For example, the wireless sensing signal 305 may be transmitted over an entire system bandwidth.

The wireless sensing signal 305 may be transmitted with a specific pattern in the time domain. For example, the wireless sensing signal 305 may be transmitted in a burst 315 including multiple pulses 320 of the wireless sensing signal 305. In some cases, there may be intervals between the pulses 320 of the burst 315. By implementing techniques described herein, these resources may be used for the wireless communication channel 310. Additionally, the wireless communication channel 310 which is outside of the burst 315 may be used for wireless communications on the wireless communication channel 310. The burst 315 may be transmitted within an affected slot 325. In some cases, some techniques for preempting or canceling a transmission within an affected slot 325 may not provide sufficient granularity to perform wireless communications in resources outside of the overlapping resources. By implementing the techniques described herein, a device may communicate on the wireless communication channel 310 during the affected slot 325 both outside of the burst 315 within the affected slot 325 but also between the pulses 320 within the burst 315.

FIG. 4 illustrates an example of a reserved occasion indication scheme 400 that supports wireless sensing indication in new radio communications in accordance with aspects of the present disclosure. In some examples, the reserved occasion indication scheme 400 may implement aspects of wireless communication system 100.

A device may transmit a wireless sensing signal on a radio frequency spectrum band that is also used for wireless communications. To prevent collisions between the wireless sensing signal and wireless communications signals, the device may indicate the presence of the wireless sensing signal. By indicating the presence of the wireless sensing signal, other wireless devices communicating on the radio frequency spectrum band may use resources on the radio frequency spectrum band which did not overlap with the wireless sensing signal for wireless communications.

In some cases, a device using the radio frequency spectrum band for wireless communications may be configured with a pattern of sensing signal occasions. A sensing occasion may either be reserved for the wireless sensing signal (e.g., a reserved occasion 405) or may not be used for the wireless sensing signal (e.g., an unreserved occasion 410) . The reserved occasions 405 may collide with wireless communications, where the unreserved occasions 410 may be available for wireless communications without a possible collision, as there may not be a sensing signal transmission in these occasions. The device may be configured with the time and frequency resources corresponding to the possible wireless sensing occasions. The time and frequency occupation pattern of the potentially transmitted wireless sensing signal may be pre-defined, pre-configured, or indicated dynamically. One example of time and frequency resources for an occupation pattern may be wireless sensing signal burst occasions, which may use the entire system bandwidth.

A reserved occasion indication 415 may be used to indicate the presence of a wireless sensing signal over a time range 420. In some cases, the duration of the time range 420 may be configurable. The reserved occasion indication 415 may be transmitted via system information, downlink control information, or RRC signaling. In some cases, the downlink control information may be UE group common downlink control information. In some examples, the reserved occasion indication 415 may be downlink control information which includes per-component carrier sub-fields for indicating reserved time and frequency resources. This may enable finer granularity for indicating reserved resources for different UEs or serving cells.

The reserved occasion indication 415 may be transmitted before or after the time range 420. For example, reserved occasion indication 415-a may be transmitted before the time range 420, and reserved occasion indication 415-b may be transmitted after the time range 420.

For reserved occasion indication 415-a, the device receiving the indication may cancel transmitting signal or channels corresponding to reserved occasions 405. For example, if the device is a UE 115, the UE 115 may cancel the transmission of uplink channels and signals at time frequency resources overlapping the wireless sensing signal in the reserved occasions 405. In some cases, the UE 115 may still transmit uplink channels and signals between pulses of the wireless sensing signal burst and in resources which do not overlap the wireless sensing signal. In some cases, reserved occasion indication 415-a may be transmitted a threshold of time before the cancelled transmission. For example, reserved occasion indication 415-a may be transmitted at least a configured amount of time (e.g., a DCI-to-cancelled-transmitting time) prior to the resources with the cancelled transmission.

For reserved occasion indication 415-b, the device receiving the indication may be informed that the channel or signal received at the corresponding time and frequency resources are not targeted for the device. For example, the device may be indicated that the wireless sensing signal collided with the original channel or signal at the time and frequency resources reserved for the wireless sensing signal. In some cases, the device may empty a buffer corresponding to the reserved resources.

FIG. 5 illustrates an example of a wireless sensing burst pattern 500 that supports wireless sensing indication in new radio communications in accordance with aspects of the present disclosure. In some examples, the wireless sensing burst pattern 500 may implement aspects of wireless communication system 100.

A device may transmit a wireless sensing signal 515 on a radio frequency spectrum band which is also used for wireless communications. For example, the wireless sensing signal 515 and a wireless communication channel 520 may occupy a portion of a millimeter wave band. Techniques described herein support indicating the presence of resources which are reserved for the wireless sensing signal 515 (e.g., reserved occasions 505) so that other devices may efficiently use the wireless communication channel 520. The device transmitting the wireless sensing signal 515 may be referred to as the sensing device and may be an example of a base station 105 or a UE 115 described herein. A neighboring device using the wireless communication channel 520 and being indicated of the wireless sensing signal 515 may be referred to as a neighboring device and may be an example of a UE 115 or a base station 105 described herein.

The wireless sensing signal 515 may be transmitted in configured time and frequency resource occasions in the radio frequency spectrum band. For example, wireless sensing occasions may be configured on the radio frequency spectrum band. A wireless sensing occasion may either be reserved for wireless sensing (e.g., a reserved occasion 505) , or the wireless sensing occasion may not be reserved or used for wireless sensing (e.g., an unreserved occasion 510) . The wireless sensing signal 515 may be transmitted during the reserved occasion 505 and may collide with wireless communications in overlapping resources. The wireless sensing signal 515 may not be transmitted during the unreserved occasions 510, and the unreserved occasions 510 may be used for wireless communications without affecting the wireless communications.

In some cases, the wireless sensing signal 515 may be transmitted in bursts 530. For example, each burst 530 may include a set of pulses 525 of the wireless sensing signal 515. The reserved occasion 505 may overlap a wireless communication channel 520, so the wireless communication channel 520 may be present between the intervals of the pulses 525.

Neighboring devices to a sensing device may be configured with the time and frequency occupation pattern for the wireless sensing occasions. In some cases, the pattern for the wireless sensing occasions may be pre-configured (e.g., via system information or RRC) , pre-defined (e.g., stored in memory at the devices) , or indicated to the devices (e.g., via RRC signaling, a MAC CE, or control information) .

In some cases, the neighboring devices to the sensing device may be indicated which of the wireless sensing occasions are reserved (e.g., reserved occasions 505) and which wireless sensing occasions are not used (e.g., unreserved occasions) . For example, the sensing device may transmit a wireless sensing occasion indication to indicate which occasions are reserved occasions 505. In some cases, the representation of the wireless sensing occasions in the indication may be a bitmap for all potential occasions within a time range. For example, each occasion within a time range may correspond to a bit of the bitmap. If a bit is toggled, then the corresponding sensing occasion may be a reserved occasion 505 for the time range. In the example of FIG. 5, the bitmap may include 8 bits, and fourth, fifth, and sixth bits of the bitmap may be toggled (e.g., the bitmap may be {0, 0, 0, 1, 1, 1, 0, 0} ) .

In another example, there may be a set of reserved sensing signal occasion patterns. For example, a maximum number of wireless sensing occasions during the time range may be pre-defined or pre-configured. For example, a number of bits less than the total number of possible occasions may be used to represent the reserved occasions 505 (e.g., instead of a bitmap) . For example, if there may only be one reserved occasion per time range, then log ₂ (N+1) bits may be used for the reserved occasion indication, where N is the total number of potential wireless sensing occasions in the time range. In another example, if the maximum number of reserved occasions 505 is limited to M, where M＜N, then

may be used for the reserved occasion indication. In some cases, the set of reserved occasions may include consecutive occasions. In this example, a start and length indicator value (SLIV) representation may be used, and

may be used for the indication.

In some other examples of waveforms (e.g., non-pulse waveforms) , there may not be a gap for wireless communications between pulses. However, these techniques may still be applied to support wireless communications around the sensing signal waveform with a high granularity.

FIG. 6 illustrates an example of a process flow 600 that supports wireless sensing indication in new radio communications in accordance with aspects of the present disclosure. In some examples, the process flow 600 may implement aspects of

wireless communication system

100 or 200. The process flow 600 may be implemented by a UE 115 or a base station 105, or both, which may be respective examples of a UE 115 and a base station 105 described with reference to FIGs. 1 and 2. In the example of the process flow 600, base station 105 transmits a wireless sensing signal. In other examples, a UE 115, or another device, may transmit the wireless sensing signal.

At 605, base station 105-b and UE 115-b may identify a pattern for a set of sensing signal occasions. The pattern may be, for example, the time frequency resources of possible sensing signal occasions as described with reference to FIGs. 4 and 5.

At 610, base station 105-b may transmit an indication that one or more of the set of sensing signal occasions are reserved for wireless detection sensing. For example, the some of the sensing signal occasions may be reserved occasions, and some of the sensing signal occasions may be unreserved. In some cases, the indication may be a bitmap, where each bit of the bitmap may correspond to a sensing signal occasion of the set of sensing signal occasions. If, for example, a bit is toggled, the corresponding sensing signal occasion may be reserved for transmitting the sensing signal. In some cases, there may be a set of reserved occasion patterns, where the indication may indicate one pattern of the set of reserved occasion patterns.

At 615, base station 105-b and UE 115-b may identify a resource allocation for communications over resources that include a first set of resources and a second set of resources. The second set of resources may overlap the one or more reserved occasions. At 620, UE 115-b may allocate the first set of resources for communications based on the indication. For example, UE 115-b may communicate on the resource allocation except for where the sensing signal overlaps the allocated resources.

At 625, base station 105-b, UE 115-b, or both, may communicate using the first set of resources. For example, base station 105-b may communicate with UE 115-b using the first set of resources of the resource allocation in accordance with the indication. At 630, base station 105-b may transmit the sensing signal during the one or more reserved occasions of the set of sensing signal occasions.

In some cases, the indication may be received after the resource allocation in the time domain. In this example, UE 115-b may determine that the second set of resources correspond to the wireless sensing detection. In some examples, UE 115-b may empty buffered information corresponding to the second set of resources. UE 115-b may still receive information from the first set of resources or use the first set of resources for communications.

In some examples, the indication may be received before the resource allocation in the time domain. In this example, UE 115-b may cancel an uplink transmission corresponding to the second set of resources. In some cases, UE 115-b may still communicate the uplink transmission on the first set of resources. In some examples, UE 115-b may cancel the uplink transmission from the first symbol of the reserved resources until a last symbol of the scheduled uplink transmission.
