Description

Technical Field

[0001] The following pertains to wireless communication, including transmission coverage technology. Background Technology

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can 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), Advanced LTE (LTE-A), or LTE-A Pro systems, and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can 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 Extended Orthogonal Frequency Division Multiple Access (DFT-S-OFDM). Wireless multiple access communication systems may include one or more base stations or one or more network access nodes, each supporting communication from multiple devices simultaneously, which may also be referred to as User Equipment (UE). In some wireless communication systems (e.g., Vehicle-to-Everything (V2X) systems), UEs may be configured to transmit data omnidirectionally, which can lead to relatively inefficient communication. For example, the UE may fail to transmit data, the UE may allocate power relatively inefficiently, or both. Summary of the Invention

[0003] The described technology relates to improved methods, systems, devices, and apparatuses supporting transmission coverage techniques. Typically, the described technology enables a user equipment (UE) to achieve directional coverage for data transmission in a wireless communication system. For example, the UE can identify one or more parameters (e.g., Quality of Service (QoS) parameters) associated with data packets to be transmitted by the UE. In some examples, a first protocol layer of the UE (e.g., the application layer) can indicate the parameters to a second protocol layer of the UE (e.g., the access layer of the UE). The UE can identify directional coverage information for data packets based on one or more parameters. The directional coverage information can indicate one or more transmission directions in which data packets are to be transmitted. For example, the directional coverage information can indicate one or more directions for transmitting data packets (e.g., a direction relative to the UE's movement, a direction relative to a reference direction), one or more weighting factors for the direction, or a combination thereof. The UE can transmit data packets according to the parameters. For example, the UE can use the directional coverage information to transmit data packets (e.g., the coverage area for data transmission can be biased towards a relatively high-priority direction). Such techniques can provide one or more potential advantages. For example, it can enable the UE to send data in a targeted manner according to a set of QoS parameters and allocate power to one or more antennas. This can result in more efficient power allocation at the UE, ensuring that the data is successfully received by other devices in the system, or both, as well as other advantages.

[0004] A method for wireless communication at a UE is described. The method may include: receiving, at a second protocol layer of the UE and from a first protocol layer of the UE, an indication of one or more quality of service (QoS) parameters associated with a data packet to be transmitted by the UE, the second protocol layer being lower than the first protocol layer; identifying directional coverage information associated with the data packet from the one or more QoS parameters, the directional coverage information indicating one or more transmission directions in which the data packet is to be transmitted; and transmitting the data packet at least according to the directional coverage information of the one or more QoS parameters.

[0005] An apparatus for wireless communication at a UE is described. The apparatus may include a processor, a memory coupled to the processor, and instructions stored in the memory. These instructions are executable by the processor to cause the apparatus to: receive, at a second protocol layer of the UE and from a first protocol layer of the UE, an indication of one or more quality of service (QoS) parameters associated with a data packet to be transmitted by the UE, the second protocol layer being lower than the first protocol layer; identify, from the one or more QoS parameters, orientation coverage information associated with the data packet, the orientation coverage information indicating one or more transmission directions in which the data packet is to be transmitted; and transmit the data packet at least according to the orientation coverage information of the one or more QoS parameters.

[0006] Another apparatus for wireless communication at a UE is described. The apparatus may include components for performing the following operations: receiving, at a second protocol layer of the UE and from a first protocol layer of the UE, an indication of one or more quality of service parameters associated with a data packet to be transmitted by the UE, the second protocol layer being lower than the first protocol layer; identifying directional coverage information associated with the data packet from the one or more quality of service parameters, the directional coverage information indicating one or more transmission directions in which the data packet is to be transmitted; and transmitting the data packet at least according to the directional coverage information of the one or more quality of service parameters.

[0007] A non-transitory computer-readable medium is described, storing code for wireless communication at a UE. The code may include processor-executable instructions to: receive, at a second protocol layer of the UE and from a first protocol layer of the UE, an indication of one or more quality of service (QoS) parameters associated with a data packet to be transmitted by the UE, the second protocol layer being lower than the first protocol layer; identify, from the one or more QoS parameters, orientation coverage information associated with the data packet, the orientation coverage information indicating one or more transmission directions in which the data packet is to be transmitted; and transmit the data packet at least according to the orientation coverage information of the one or more QoS parameters.

[0016] In some wireless communication systems, devices can communicate data with other devices. For example, a UE (e.g., a vehicle) can communicate data packets with other UEs via sidelink communication in a wireless communication system (e.g., a vehicle-to-everything (V2X) system). In some cases, data packets may include information that is relatively more relevant to certain directions. As an illustrative example, a UE may transmit V2X data packets indicating an object detected in front of the UE. This information may be relatively more relevant to a UE behind the UE than to a UE in front of the UE. However, a UE can be configured to transmit such data packets omnidirectionally, which may result in relatively inefficient communication (e.g., the UE may fail to transmit data successfully, the UE may allocate power for data transmission relatively inefficiently, or both).

[0017] The techniques described herein enable devices in wireless communication systems to achieve directional coverage for data transmission. For example, a UE can identify one or more parameters associated with data packets to be transmitted by the UE. In some examples, a first protocol layer of the UE (e.g., the application layer) can indicate parameters to a second protocol layer of the UE (e.g., the access layer of the UE). As an illustrative example, the application layer can indicate quality of service (QoS) parameters associated with data packets (e.g., V2X multicast range parameters), QoS parameters associated with data streams (e.g., resource type, priority, packet delay budget, packet error rate, etc.), or combinations thereof, as well as examples of other parameters. Parameters may include directional coverage information associated with data packets and / or data streams. For example, parameters may indicate the direction for transmitting data packets relative to the UE's direction of motion (e.g., in the direction of motion, perpendicular to the direction of motion, opposite to the direction of motion, or a combination thereof). Additionally or alternatively, parameters may indicate the direction for transmitting data packets relative to a reference frame (e.g., a reference direction such as north, east, west, south, or a combination thereof). In some examples, directional coverage information may include combinations of directions, one or more weighting factors (e.g., each weighting factor indicating the relative importance of the corresponding direction), or both.

[0018] In some examples, the UE can assign data packets to a data stream (e.g., a QoS stream) based on a mapping between QoS parameters indicated by the application layer (e.g., including directional coverage information) and a set of configured QoS streams (e.g., the UE can select a QoS stream with a different set of parameters based on this mapping). The UE can determine the radio bearer used to transmit the data packets based on the selected data stream. The UE can transmit data packets according to parameters. For example, the UE can use directional coverage information to transmit data packets (e.g., the coverage area for data transmission can be biased towards a relatively high priority direction based on parameters). In some examples, the UE can identify one or more transmit antennas and / or transmit precoders based on directional coverage information (e.g., power splitting on a selected set of transmit antennas). Additionally or alternatively, as described herein, the UE can transmit one or more retransmissions of data packets based on one or more parameters (e.g., the UE can transmit each retransmission using a corresponding set of parameters based on directional coverage information).

[0019] This technology can generate one or more potential advantages. For example, it can enable the UE to send data in a targeted manner according to a set of QoS parameters and allocate power to one or more antennas, which can lead to more efficient power allocation at the UE, ensuring that the data is successfully received by other devices in the system, or both, as well as other advantages.

[0020] The aspects of this disclosure are initially described in the context of a wireless communication system. These aspects are then described in the context of block diagrams and process flows. The aspects of this disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts related to transmission coverage techniques.

[0021] Figure 1 An example of a wireless communication system 100 supporting transmission coverage technologies according to various aspects of this disclosure is shown. The wireless communication 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 communication system 100 may be a Long Term Evolution (LTE) network, an LTE-A Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0022] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 over the coverage area. Coverage area 110 can be an example of a geographical area over which base station 105 and UE 115 can support signal communication according to one or more radio access technologies.

[0023] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be fixed or mobile, or fixed or mobile at different times. UE 115 can be devices of different forms or with different capabilities. Figure 1 Some example UE 115s are shown in the document. The UE 115 described herein is capable of communicating with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as... Figure 1 As shown.

[0024] Base station 105 may communicate with core network 130, communicate with each other, or both. For example, base station 105 may interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) or both via backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 may be or may include one or more radio links.

[0025] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, NodeB, eNodeB (eNB), next-generation NodeB or giga-NodeB (any of which may be referred to as gNB), home NodeB, home eNodeB or other suitable terms.

[0026] In other examples, UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client. UE 115 may also include or 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 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, and other examples, which may be implemented in various objects such as home appliances or vehicles, meters, and other examples.

[0027] The UE 115 described in this document can communicate with various types of devices, such as other UEs 115 that can sometimes act as relays, as well as base stations 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.

[0028] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion (e.g., bandwidth portion (BWP)) of a radio frequency spectrum band that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-APro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operations for carriers, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0029] The signal waveform transmitted via a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can consist of one symbol period (e.g., the duration of a modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate the UE 115 can potentially achieve. Wireless communication resources can refer to a combination of radio spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further improve the data rate or data integrity for communication with the UE 115.

[0030] The time interval between base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f This can represent the maximum supported discrete Fourier transform (DFT) size. Communication resources can be organized into time intervals based on radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by its System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0031] 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, a frame may be divided (e.g., in the time domain) into subframes, 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 preceding each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N) f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0032] A subframe, time slot, mini-slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0033] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend over the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more UEs 115 can monitor or search for control regions for control information based on one or more search space sets, and each search space set can include one or more control channel candidates at one or more aggregation levels arranged in a cascaded manner. The aggregation level for control channel candidates can refer to the number 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 set can include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set for sending control information to a specific UE 115.

[0034] In some examples, base station 105 may be mobile, and thus provide communication coverage for mobile geographic coverage areas 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, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0035] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services (such as mission-critical key-push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0036] In some examples, UE 115 can also communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in this group may be outside the geographic coverage area 110 of base station 105 or may not be able to receive transmissions from base station 105 in other ways. In some examples, the group of UE 115s communicating via D2D communication can utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates resource scheduling for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.

[0037] 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., UE 115). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. Vehicles may signal information related to traffic conditions, signal control, weather, safety, emergencies, or any other information related to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (e.g., roadside units) via vehicle-to-network (V2N) communication through one or more network nodes (e.g., base station 105), or with the network, or with both.

[0038] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) managing access and mobility, and at least one user plane entity routing 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 can manage non-access stratum (NAS) functions associated with core network 130 for UE 115 served by base station 105, such as mobility, authentication, and bearer management. User IP packets can be delivered through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to the network operator's IP service 150. Carrier IP services 150 may include access to the Internet, one or more intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0039] Some network devices, such as base station 105, may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio headends and ANCs) or combined into a single network device (e.g., base station 105).

[0040] Wireless communication system 100 can operate using one or more frequency bands typically in the range of 300 MHz to 300 GHz. The region from 300 MHz to 3 GHz is generally referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range is from approximately 1 decimeter to 1 meter. UHF waves may be blocked or deflected by buildings and environmental features, but these waves can penetrate structures sufficiently to enable macrocells to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions may be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0041] The wireless communication system 100 can utilize both licensed and unlicensed radio spectrum bands. For example, the wireless communication system 100 can use Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands can be combined with component carriers operating in licensed bands based on carrier aggregation configurations (e.g., LAA). Operation in unlicensed spectrum can include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, and other examples.

[0042] Base station 105 or 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) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operation 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, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports, which base station 105 may use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Alternatively or additionally, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0043] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or manipulate an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming is achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to the antenna array in a particular azimuth experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include the transmitting or receiving device applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each antenna element can be defined by a beamforming weight set associated with a specific direction (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other direction).

[0044] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for communication over logical channels. The Medium Access Control (MAC) layer can perform priority processing and multiplex logical channels into transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of RRC connections between the UE 115 and the base station 105 or core network 130 that supports user plane data radio bearers. At the physical layer, transmit channels can be mapped to physical channels.

[0045] The wireless communication system 100 can support sidelink communication between devices. For example, UE 115 can communicate with other UE 115s via communication link 135. Besides other examples of wireless devices, UE 115 can also be an example of a vehicle or a vulnerable road user (VRU). UE 115 can communicate one or more data packets via sidelink transmission (e.g., a vehicle can directionally transmit data based on one or more QoS parameters).

[0046] The techniques described herein enable devices in a wireless communication system 100 to achieve directional coverage for data transmission. For example, UE 115 can identify one or more parameters associated with data packets to be transmitted by UE 115. In some examples, a first protocol layer (e.g., application layer) of UE 115 can indicate parameters to a second protocol layer (e.g., access layer) of UE 115. As an illustrative example, the application layer may indicate QoS parameters associated with data packets (e.g., V2X multicast range parameters), QoS parameters associated with data streams (e.g., resource type, priority, packet delay budget, packet error rate, etc.), or combinations thereof, as well as examples of other parameters. Parameters may include directional coverage information associated with data packets and / or data streams. For example, parameters may indicate the direction for transmitting data packets relative to the direction of movement of UE 115 (e.g., in the direction of movement, perpendicular to the direction of movement, opposite to the direction of movement, or a combination thereof). Additionally or alternatively, parameters may indicate the direction for transmitting data packets relative to a reference frame (e.g., a reference direction such as north, east, west, south, or a combination thereof). In some examples, directional coverage information may include a combination of directions, one or more weighting factors (e.g., each weighting factor indicating the relative importance of the respective directions), or a combination thereof.

[0047] In some examples, UE 115 may assign data packets to a data stream (e.g., a QoS stream) based on a mapping between QoS parameters indicated by the application layer (e.g., including directional coverage information) and a configured set of QoS streams (e.g., UE 115 may select a QoS stream with a different set of parameters based on this mapping). UE 115 may determine the radio bearer for transmitting data packets based on the selected data stream. UE 115 may transmit data packets according to parameters. For example, UE 115 may use directional coverage information to transmit data packets (e.g., the coverage area for data transmission may be biased towards a relatively high priority direction based on parameters). In some examples, UE 115 may identify one or more transmit antennas and / or transmit precoders (e.g., power splitting on the selected set of transmit antennas) based on directional coverage information. Additionally or alternatively, as described herein, UE 115 may transmit one or more retransmissions of data packets according to one or more parameters (e.g., UE 115 may use a corresponding set of parameters based on directional coverage information to transmit each retransmission).

[0048] Figure 2 An example of a wireless communication system 200 supporting transmission coverage technology according to various aspects of this disclosure is shown. In some examples, the wireless communication system 200 may implement various aspects of the wireless communication system 100. For example, the wireless communication system 200 may include device 205, which may be a reference device. Figure 1 An example of a UE 115 (e.g., a vehicle) is described. Generally, wireless communication system 200 illustrates an example of device 205 implementing directional information (e.g., transmission coverage bias) for sidelink communication.

[0049] Device 205 can communicate using a sidelink within coverage area 215, where the coverage area can be a reference. Figure 1 Examples of coverage area 110 described. In some examples, device 205 may be an example of a UE, vehicle, VRU, pedestrian device, drone, roadside unit (RSU), or any combination thereof, as well as other examples of wireless devices. As an illustrative example, device 205-a may be a vehicle that uses sidelink communication in a V2X communication system to communicate data with other vehicles (e.g., devices 205-b, 205-c, and 205-d).

[0050] In some examples, device 205 may include one or more TRPs. A TRP may be an example of an array of one or more antennas capable of transmitting wireless communication (e.g., a transmitting antenna for transmitting signal 210) and receiving wireless communication. In some examples, the TRPs of device 205 may correspond to coverage areas of communication. For example, a TRP located on the front bumper or front roof of a vehicle may result in a larger transmission coverage area for the front or sides of the vehicle (e.g., from 90 degrees to 270 degrees on an azimuth diagram, and other examples of values ​​and coverage area patterns), a TRP located on the rear roof or rear bumper of the vehicle may result in a larger transmission coverage area for the rear and / or sides of the vehicle, and so on. In some examples, device 205 may include multiple TRPs for communication in wireless communication system 200. For example, device 205-a may include multiple TRPs and may use multiple TRPs to transmit signal 210. By using multiple TRPs to transmit signal 210, device 205-a may achieve a relatively high coverage area (e.g., device 205-a may achieve a 360-degree coverage area using multiple TRPs) and other advantages.

[0051] Device 205-a can identify data packets to be communicated to one or more other devices 205. For example, an application of device 205-a can generate data packets for sidelink communication with other devices 205. In some examples, data packets (e.g., V2X packets) may be relatively more relevant to communication in certain directions compared to other directions. That is, a data packet may be associated with a directionality that is more relevant to the data information in the packet than to other directions. As an illustrative example, device 205-a can exchange messages indicating forward collision warnings with devices 205-b, 205-c, and 205-d. For example, device 205-a can use sensor information to determine a possible collision with device 205-b, and device 205-a can indicate a possible collision via a sidelink message. The sidelink message may be relatively more relevant to a direction toward device 205-b (e.g., forward or approaching) than to a direction toward device 205-c (e.g., backward or reversing direction) or device 205-d (e.g., lateral direction). For example, device 205-b may use a collision warning to take action (e.g., lane change, increase speed, etc.), while such information may not be used by devices 205-c or 205-d.

[0052] As another illustrative example, device 205-b can detect objects in front of it and may attempt to share sensor information via a side-link message indicating the detected object. This information may be more relevant to transmissions to devices 205-a, 205-c, and 205-d in the rearward direction (e.g., the reverse direction). As another illustrative example, coordinated driving messages for lane changes may be more relevant to the lateral and rearward directions (e.g., messages indicating future maneuvers such as lane changes may be more relevant to the direction of vehicles with a possible collision path associated with the future maneuver).

[0053] Device 205-a can be configured to transmit such data packets via signal 210, which could be an example of sidelink transmission (e.g., multicast messages). In some examples, device 205-a can be configured to transmit signal 210 omnidirectionally. However, such omnidirectional communication can lead to poorer performance of the wireless communication system 200, for example, if the data packets contain information that is relatively more relevant in some directions than others. For instance, device 205-a might allocate relatively higher power to the TRP transmission signal 210 in directions less relevant to signal 210, or it might allocate relatively lower power to the TRP transmission signal 210 in directions more relevant to signal 210, which could result in inefficient power usage or reduce the likelihood that the target device 205 might receive directional information from the data packets.

[0054] According to the techniques described herein, device 205 can implement directional coverage for data transmission (e.g., device 205-a can use one or more indications from the application layer of device 205-a to transmit signal 210 in a directional manner). For example, device 205-a can identify one or more parameters associated with data packets to be transmitted by device 205-a. In some examples, a first protocol layer (e.g., the application layer) of device 205-a can indicate parameters to a second protocol layer (e.g., the access layer of device 205-a). As an illustrative example, the application layer may indicate quality of service (QoS) parameters associated with data packets (e.g., V2X multicast range parameters), QoS parameters associated with data streams (e.g., resource type, priority, packet delay budget, packet error rate, etc.), or combinations thereof, as well as examples of other parameters. Parameters may include directional coverage information associated with data packets and / or data streams. For example, parameters may indicate the direction for transmitting data packets relative to the direction of movement of device 205-a (e.g., in the direction of movement, perpendicular to the direction of movement, opposite to the direction of movement, or a combination thereof). Additionally or alternatively, parameters may indicate the direction used to transmit data packets relative to a reference frame (e.g., a reference direction such as north, east, west, south, or a combination thereof). In some examples, orientation coverage information may include a combination of directions, one or more weighting factors (e.g., each weighting factor indicating the relative importance of the respective direction), or both.

[0055] In some examples, device 205-a can assign data packets to data streams (e.g., QoS streams) based on a mapping between QoS parameters (e.g., including directional coverage information) indicated by the application layer and a configured set of QoS streams (e.g., device 205-a can select QoS streams with different parameter sets based on this mapping). Device 205-a can determine the radio bearer for transmitting data packets based on the selected data stream. Device 205-a can transmit data packets according to the parameters. For example, device 205-a can transmit signal 210 from its access layer using parameters indicated by its application layer (e.g., the coverage area of ​​signal 210 can be biased towards a relatively high priority direction based on coverage information indicated by the parameters).

[0056] In some examples, device 205-a can identify one or more TRPs (e.g., device 205-a can select one or more transmit antennas to transmit signal 210) and / or transmit precoders (e.g., power splitting on the selected set of transmit antennas) based on directional coverage information. This technique allows device 205-a to adjust the shape of signal 210 (e.g., the coverage area of ​​signal 210 can be configured to be directional using these parameters). The access layer of device 205-a can determine one or more TRPs (e.g., one or more transmit antennas of one or more TRPs) and one or more power parameters of each of the one or more TRPs in order to transmit signal 210 according to the directional coverage information. As an illustrative example, in addition to other examples of direction and coverage area, if the coverage information indicates a more relevant forward direction, the coverage area of ​​signal 210 can be more directed towards device 205-b.

[0057] Additionally or alternatively, device 205-a may transmit one or more retransmissions of data packets based on one or more QoS parameters (e.g., device 205-a may use a corresponding set of parameters based on directional coverage information to transmit each retransmission), as referenced herein. Figure 4 As stated above.

[0058] Figure 3 An example block diagram 300 supporting transmission coverage techniques according to various aspects of this disclosure is shown. In some examples, block diagram 300 may implement aspects of wireless communication system 100 or wireless communication system 200. For example, block diagram 300 may illustrate inter-layer operation within a wireless device, for example, with reference to... Figure 1 and Figure 2 The UE 115 or device 205 described.

[0059] The device can generate data packet 305, which can be an example of a V2X data packet used for V2X communication. For example, the device's application can generate information to be sent to other devices (e.g., sensor information, collision indication, or other examples of data included in sidelink messages, as described herein). Data packet 305 can be processed by a first protocol layer 310. The first protocol layer 310 can be an example of the device's application layer. For example, the first protocol layer can include or can be an example of aspects of V2X layer 315. The first protocol layer 310 can classify and label PC5 user plane traffic. For example, the first protocol layer 310 can associate PC5 traffic with QoS flows at QoS rule 320. Although shown separately for clarity, it should be understood that QoS rule 320 can be included in V2X layer 315.

[0060] As an illustrative example, the device can identify one or more QoS parameters requested by an application of the device. The device can assign data packets 305 to a QoS flow based on the identified parameters. For example, the device can determine the QoS flow corresponding to the QoS parameters (e.g., the device can be configured with multiple QoS flows, each corresponding to a corresponding set of QoS parameters). The device can indicate a QoS flow identifier (ID) to other layers, which allows those layers to determine the QoS parameters used to send data packets (e.g., other layers can be configured with a set of QoS parameters for the provided QoS flow ID).

[0061] One or more QoS parameters may include per-flow parameters and / or per-packet parameters. For example, the first protocol layer 310 may indicate a QoS flow ID, which may correspond to a set of per-flow QoS parameters, such as resource type parameters (e.g., an indication of guaranteed bit rate (GBR), an indication of delay-critical GFBR, or an indication of non-GBR resource types, and other examples), priority parameters, packet delay budget parameters, packet error rate parameters (e.g., an estimated packet error rate), average window (e.g., for GBR and delay-critical GBR resource types), maximum data burst size (e.g., for delay-critical GBR resource types), or any combination thereof, and other examples of per-flow QoS parameters. Additionally or alternatively, the first protocol layer 310 may indicate a per-packet QoS parameter (e.g., for dynamic control of individual data packets in a data flow), such as a range parameter (e.g., an indication of the minimum distance at which a device can satisfy a QoS parameter), for example, for V2X multicast operations.

[0062] First protocol layer 310 may send indications 325 to one or more other layers, indicating data packets or one or more QoS parameters. For example, first protocol layer 310 may indicate one or more QoS parameters (e.g., via QoS flow ID and / or one or more per-packet QoS parameters) to second protocol layer 340, which may be an example of an access layer (e.g., a user protocol stack). Service Data Adaptation Protocol (SDAP) layer 330 may map PC5 QoS flows to sidelink radio bearers based on the QoS parameters indicated from first protocol layer 310. Although shown separately for clarity, it should be understood that SDAP layer 330 may be included within second protocol layer 340. SDAP layer 330 may indicate bearers, one or more QoS parameters, data packets, or any combination thereof to other layers. For example, PDCP layer 345, RLC layer 350, MAC layer 355, and / or physical (PHY) layer 360 may receive these indications and send data packets according to one or more QoS parameters, as described herein.

[0063] According to the techniques described herein, block diagram 300 can support the transmission of directional coverage information for data packets. For example, a first protocol layer 310 (e.g., an application layer) can indicate directional coverage information (e.g., transmit a coverage bias indication) to a second protocol layer 340. In some examples, the directional coverage information can be on a per-flow basis, which can reduce the signaling overhead used for indication parameters. For example, the parameter indicating the directional coverage information can correspond to a QoS data stream ID. The access layer can identify the parameter indicating the directional coverage information by determining the set of parameters corresponding to the QoS data stream ID indicated from the application layer. The access layer can utilize the indicated directional coverage information for multiple data packets included in the data stream. Additionally or alternatively, the directional coverage information can be implemented on a per-packet basis. For example, the application layer can send parameters indicating directional coverage information for data packets to the access layer, which can provide dynamic control of directional coverage for each data packet in the data stream.

[0064] Orientation coverage information parameters can indicate the direction in which data packets are transmitted relative to the direction of movement of the device (e.g., in the direction of movement, perpendicular to the direction of movement, opposite to the direction of movement, or a combination thereof). Additionally or alternatively, parameters can indicate the direction in which data packets are transmitted relative to a reference frame (e.g., a reference direction such as north, east, west, south, or a combination thereof). In some examples, orientation coverage information can include direction, one or more weighting factors (e.g., each weighting factor indicating the relative importance of the corresponding direction), or both, such as a reference frame. Figure 4 As stated above.

[0065] The device can use parameters indicated by the device's application layer to transmit data packets (e.g., based on coverage information indicated by the parameters, the coverage area carrying the data packets can be biased towards a relatively high-priority direction). In some examples, the device can identify one or more TRPs and / or transmit precoders based on directional coverage information. Additionally or alternatively, the device can transmit one or more retransmissions of data packets based on one or more QoS parameters (e.g., the device can use a corresponding set of parameters based on directional coverage information to transmit each retransmission), as referenced. Figure 4 As stated above.

[0066] Figure 4 An example of a process flow 400 supporting transmission coverage techniques according to various aspects of this disclosure is shown. In some examples, process flow 400 may implement aspects of wireless communication system 100 or wireless communication system 200. For example, process flow 400 may illustrate the operation of the protocol layer of device 205-e, which may be as described in reference... Figure 1-3 The UE 115 or device 205 is an example. Device 205-e may include a first protocol layer 405-a and a second protocol layer 405-b, which may be as described in reference... Figure 3 Examples of the first protocol layer 310 (e.g., application layer) and the second protocol layer 340 (e.g., access layer).

[0067] At 410, the first protocol layer 405-a can determine one or more parameters. For example, the first protocol layer 405-a can receive data packets from the application of device 205-e for sidelink communication with other devices 205. The first protocol layer 405-a can also receive indications of requested QoS parameters associated with the data packets and / or data streams including the data packets (e.g., the application of device 205-e can indicate data latency tolerance, data priority, etc.). In some examples, the first protocol layer 405-a can assign data packets to QoS data streams based on a mapping between requested (e.g., desired) QoS parameters and a pre-configured set of QoS data streams (e.g., each QoS data stream can be configured with a corresponding set of QoS parameters). Thus, as referenced... Figure 3 The first protocol layer 405-a may determine one or more per-flow parameters (e.g., a set of parameters corresponding to an assigned QoS data flow ID), one or more per-packet parameters (e.g., dynamic parameters corresponding to a data packet), or a combination thereof.

[0068] These parameters may include indications of directional coverage information. For example, one or more per-stream parameters, one or more per-packet parameters, or combinations thereof may include directional coverage information for data packets, data streams including data packets, or both. In some examples, parameters may indicate the direction (e.g., in the direction of movement, perpendicular to the direction of movement, opposite to the direction of movement, or a combination thereof) for transmitting data packets relative to the direction of movement of device 205-e. For example, parameters may indicate transmission in front of the vehicle (e.g., in the direction of movement), to the left or right of the vehicle, behind the vehicle, or a combination thereof. In some examples, parameters may indicate the direction of transmitting data packets relative to a reference frame (e.g., a global reference frame). For example, parameters may indicate a reference direction for transmitting data, such as north, east, west, south, or a combination thereof. In some examples, directional coverage information may include combinations of directions, one or more weighting factors (e.g., each weighting factor indicating the relative importance of the corresponding direction), or both (e.g., parameters may indicate the direction and the relative amplitude of the signal transmitted in that direction). As an illustrative example, in addition to other examples of direction indication and weighting factors, coverage information (e.g., QoS parameters that include coverage information) can indicate the transmission of data packets or data streams with a relative amplitude of 1.0 in the forward direction, a relative amplitude of 0.2 in the backward direction, a relative amplitude of 0.1 in the left direction, and a relative amplitude of 0.2 in the right direction.

[0069] At 415, the first protocol layer 405-a may send an indication to the second protocol layer 405-b. This indication may specify data packets and determined parameters. For example, the first protocol layer 405-a may assign data packets or data streams to QoS stream IDs based on a mapping between requested parameters and a configured set of QoS data streams. This indication may then specify the QoS stream IDs to the second protocol layer 405-b. Additionally or alternatively, the indication may include one or more per-packet parameters (e.g., range parameters and / or orientation coverage information parameters).

[0070] At 420, the second protocol layer 405-b can identify one or more parameters. For example, the second protocol layer 405-b can receive an indication 415 and can use the indication 415 to identify QoS parameters for transmitting data packets (e.g., the second protocol layer 405-b can use a pre-configured set of parameters associated with the indicated QoS data stream, the indication may include one or more parameters, such as directional coverage information parameters, etc.). The second protocol layer 405-b can use the identified parameters to determine directional coverage information for transmitting data. For example, the second protocol layer can identify one or more directions for transmitting data packets or data streams (e.g., the parameters may indicate one or more directions, weighting factors, or both).

[0071] In some examples, at 425, the second protocol layer 405-b can determine the radio bearer used for transmitting data. For example, the second protocol layer 405-b can map an allocated QoS data stream to a sidelink radio bearer that satisfies the QoS parameters associated with the QoS data stream. Therefore, the second protocol layer 405-b can determine the radio bearer based on this mapping and transmit data via the determined radio bearer.

[0072] In some examples, at 430, the second protocol layer 405-b may determine an antenna, a precoder, or both. For example, the second protocol layer 405-b may identify one or more TRPs for transmitting signals based on QoS parameters. As an illustrative example, QoS parameters may include directional coverage information indicating that data packets are transmitted with a relatively greater intensity in the forward direction than in the backward direction (e.g., such that the shape of the transmitted coverage area is relatively larger in the forward direction than in the backward direction). The second protocol layer 405-b may select a TRP located in the indicated direction (e.g., a TRP in front of a vehicle), which may cause the transmitted coverage area to be directionally biased in that direction. Additionally or alternatively, the second protocol layer 405-b may select a subset of transmit antennas (e.g., TRPs) for transmitting data. For example, the second protocol layer 405-b may select multiple transmit antennas and determine a transmit precoder to directionally bias the transmitted coverage area according to the directional coverage information. The second protocol layer 405-b may allocate power to each transmit antenna to obtain the indicated directional coverage. As an illustrative example, in addition to other examples of directionality and precoders, if the front direction is weighted more heavily than the rear direction, more power can be allocated to the front antenna to distribute the power split between the front and rear antennas. This technique can yield one or more advantages. For example, selecting transmit antennas and / or power parameters (e.g., based on the power allocation of the precoder) can achieve greater transmit coverage toward the relatively more relevant direction, reduce ineffective power use in the relatively less relevant direction, or both, as well as other advantages.

[0073] At 430, the second protocol layer 405-b can transmit data packets according to parameters. For example, data packets can be transmitted using a determined radio bearer associated with the QoS parameter set, a determined TRP that satisfies the parameters' directional coverage information, and a precoder (e.g., power splitting between antennas).

[0074] Additionally or alternatively, device 205-e may transmit one or more retransmissions of data packets based on one or more QoS parameters. For example, device 205-e may determine the number of retransmissions of a data packet (e.g., the data packet may be transmitted 3 times based on one or more QoS parameters). Device 205-e may identify a corresponding set of parameters for each transmission of data based on the QoS parameters (e.g., the QoS parameter set may be selected for each transmission based on desired directional coverage information). As an illustrative example, the QoS parameters may indicate a weighting factor of 1.0 for a first direction (e.g., forward direction, north, etc.) and a weighting factor of 0.2 for a second direction (e.g., backward direction, south direction, etc.). Device 205-e may identify a corresponding set of TRPs and / or parameters for each retransmission. For example, device 205-e may transmit data in a first transmission using a previous TRP, in a second transmission using a previous TRP, and in a third transmission using a subsequent TRP. Additionally or alternatively, device 205-e may use different precoders (e.g., power allocation) for each transmission via multiple transmit antennas such that the aggregated coverage area of ​​all retransmissions satisfies the indicated QoS parameters (e.g., the aggregated shape of the retransmission signals satisfies the indicated direction and weighting factor).

[0075] Figure 5 A block diagram 500 of a device 505 supporting transmission coverage technology according to various aspects of this disclosure is shown. Device 505 may be an example of various aspects of UE 115 as described herein. Device 505 may include a receiver 510, a communication manager 515, and a transmitter 520. Device 505 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

In some examples, according to various aspects of this disclosure, the communication manager 515 or its subcomponents may be combined with one or more other hardware components, including but not limited to input / output (I / O) components, transceivers, network servers, another computing device, one or more other components described in this disclosure, or combinations thereof.

[0080] The communication manager 515 described herein can be implemented to realize one or more potential advantages at device 505, the processor of device 505, a communication system including device 505, or a combination thereof. As described herein, one implementation may allow device 505 to direct bias towards the transmission coverage area of ​​data packets based on QoS parameters. These techniques may also improve communication efficiency, reduce power usage, or both, among other advantages.

[0081] Transmitter 520 can transmit signals generated by other components of device 505. In some examples, transmitter 520 can be co-located with receiver 510 in a transceiver module. For example, transmitter 520 can be combined with... Figure 8 Examples of various aspects of the transmitter 820 are described. The transmitter 820 may utilize a single antenna or an array of antennas.

[0082] Figure 6 A block diagram 600 of a device 605 supporting transmission coverage technology according to various aspects of this disclosure is shown. Device 605 may be an example of an aspect of device 505 or UE 115 as described herein. Device 605 may include a receiver 610, a communication manager 615, and a transmitter 635.

[0089] Figure 7 A block diagram 700 of a communication manager 705 supporting transmission coverage technology according to various aspects of this disclosure is shown. The communication manager 705 may be an example of aspects of the communication manager 515, communication manager 615, or communication manager 810 described herein. The communication manager 705 may include an instruction receiver 710, a coverage information component 715, a data transmitter 720, an allocation component 725, a radio bearer component 730, an antenna component 735, a TRP component 740, and a quantity component 745. Each of these modules may communicate directly or indirectly with each other (e.g., via one or more buses).

[0090] The receiver 710 indicates that it can receive, at and from the UE's first protocol layer, an indication of one or more quality of service parameters associated with data packets to be transmitted by the UE, wherein the second protocol layer is lower than the first protocol layer. In some cases, the UE includes a vehicle, the first protocol layer includes an application layer, the second protocol layer includes an access layer, or any combination thereof.
