[0003] The following generally relates to wireless communication and, more particularly, to concurrent sidelink and uplink transmission. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. These systems are capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multi - 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 that may be referred to as New Radio (NR) systems. These systems may employ techniques such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT - S - OFDM). A wireless multi - access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication for multiple communication devices, which may also be referred to as User Equipment (UE).

[0005] A UE may communicate with a base station via an uplink communication channel in a first resource and may also communicate with an adjacent UE via a sidelink communication channel in a second resource different from the first resource. Traditional uplink and sidelink communication techniques may be insufficient. Summary of the Invention

The UE may send concurrent messages to other UEs via a sidelink communication channel and may also send an uplink communication channel to a base station. The UE may send a report indicating the UE's ability to perform concurrent transmissions on the sidelink channel and the uplink channel. The UE may receive a transmission configuration from the base station based on the report, the transmission configuration scheduling concurrent sidelink and uplink transmissions within resources shared by the sidelink channel and the uplink channel. Then, the UE may send the concurrent sidelink and uplink transmissions within the resources shared by the sidelink channel and the uplink channel based on the transmission configuration. Other UEs and one or more base stations may receive the concurrent sidelink and uplink transmissions and may decode different layers of the transmissions based on the received channel quality at the device.

[0054] A user equipment (UE) may communicate with a base station via an uplink channel and may also communicate with an adjacent UE via a sidelink communication channel. A UE communicating with other adjacent UEs via the sidelink channel may be an example of a vehicle in a vehicle-to-vehicle (V2V) or vehicle-to-everything (V2X) wireless communication system. In some cases, separate resources may be allocated for sidelink transmission and uplink transmission, such as in a traditional Mode-1 V2X system. The UE may perform channel monitoring, which may include periodic channel measurements, such as measurements of the signal-to-noise ratio (SNR) of one or more channels. The sidelink communication channel may sometimes have a lower SNR than the uplink communication channel. This SNR mismatch may be exploited to obtain higher throughput communication for the transmitting UE.

[0055] In one example, the UE may transmit sidelink communication in a basic layer, and the UE may transmit uplink communication in an enhanced layer. For example, the UE may encode data to be transmitted in a sidelink channel (e.g., a physical sidelink shared channel (PSSCH)) as the basic layer and encode data to be transmitted in a physical uplink shared channel (PUSCH) as the enhanced layer. The basic layer and the enhanced layer may be superimposed in a superimposed transmission such that the UE may transmit the basic layer and the enhanced layer simultaneously. The basic layer in the superimposed transmission may be encoded based on a weaker link (e.g., based on a channel with a lower SNR), and the enhanced layer may be encoded based on a stronger link (e.g., based on a channel with a higher SNR). Thus, the UE may transmit a concurrent transmission within the same resource including the basic layer and the enhanced layer, which may result in higher spectral efficiency.

[0056] A UE that simultaneously transmits concurrent sidelink (SL) and uplink (UL) communications (e.g., concurrent SL and UL or Uu transmissions) can indicate to the base station an intention to perform concurrent transmissions, or can convey to the base station an indication of the ability to perform concurrent transmissions. In some cases, the UE can send a report to the base station indicating the ability to perform concurrent transmissions. The ability report can be accomplished using a UE capability message, transmission of an information element indicating the ability, or other types of messages. In some cases, the report can be an implicit indication that the UE is capable of performing concurrent transmissions. For example, the UE can indicate a transmission mode that includes the ability to perform concurrent transmissions. The base station can authorize sidelink and uplink resources based on the UE's intention or ability. The UE can then encode the data to be transmitted concurrently and can send the concurrent base layer and enhancement layer over the sidelink and uplink channels.

[0057] Due to the lower SNR in the sidelink channel, the receiving UE may be able to decode the base layer that may include the sidelink transmission message, and due to the lower SNR in the sidelink channel, the receiving UE may not be able to receive the enhancement layer. Due to the higher SNR in the uplink channel, the base station can receive and decode the transmitted base layer and enhancement layer, and the base station can be able to decode the relevant uplink information in the concurrent transmission by eliminating the base layer from the received transmission to obtain the enhancement layer. Thus, the same resource allocation can be used to send information over the sidelink channel and the uplink channel.

[0058] Aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects of the present disclosure are described in the context of process flow diagrams. Aspects of the present disclosure are further illustrated and described by means of block diagrams, system diagrams, and flowcharts related to concurrent sidelink and uplink transmissions.

[0059] Figure 1 An example of a wireless communication system 100 that supports concurrent sidelink and uplink transmissions in accordance with aspects of the present disclosure is illustrated. The wireless communication system 100 can 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 can 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 communication system 100 can 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.

[0060] Base stations 105 can be dispersed throughout a geographical area to form a wireless communication system 100 and can be devices of different forms or with different capabilities. The base stations 105 and the UEs 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and the UEs 115 and the base stations 105 can establish one or more communication links 125 over the coverage area 110. The coverage area 110 can be an example of a geographical area over which the base stations 105 and the UEs 115 can support signal communication according to one or more radio access technologies.

[0061] The UEs 115 can be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary or mobile, or both, at different times. The UEs 115 can be devices of different forms or with different capabilities. Figure 1 The figure illustrates some exemplary UEs 115. As Figure 1 shown, the UEs 115 described herein can be capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices).

[0062] The base stations 105 can communicate with the core network 130, or with each other, or both. For example, the base stations 105 can be connected to the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 can communicate with each other directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130) or both via the backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, the backhaul links 120 can be or can include one or more wireless links.

[0063] One or more of the base stations 105 described herein can include or can be referred to by those of ordinary skill in the art as base station transceivers, radio base stations, access points, radio transceivers, NodeB, eNodeB (eNB), next-generation NodeB, or giga-NodeB (any of which can be referred to as gNB), home NodeB, home eNodeB, or other suitable terms.

[0064] The UE 115 may include or may be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, where "device" may also be referred to as a unit, station, terminal, or client, etc. The UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, the UE 115 may include or may be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances, vehicles, meters, etc.

[0065] As Figure 1 shown, the UE 115 described herein may be capable of communicating with various types of devices, such as other UE 115s that may sometimes act as relays, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc.

[0066] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on 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 link 125. For example, a carrier for the communication link 125 may include a portion (e.g., bandwidth part (BWP)) of a radio frequency band operating according to one or more physical layer channels of a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operation, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. According to a carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0067] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have control signaling that captures signaling or coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel raster used for discovery by UE 115. A carrier may operate in an independent mode in which initial capture and connection may be made by UE 115 via the carrier, or a carrier may operate in a non-independent mode in which another different carrier (e.g., of the same or a different radio access technology) is used to anchor the connection.

[0068] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from UE 115 to the base station 105, or a downlink transmission from the base station 105 to UE 115. A carrier may carry downlink communication or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink communication and uplink communication (e.g., in TDD mode).

[0069] 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 the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of determined bandwidths for a carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication on a particular carrier bandwidth, or may be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of a carrier bandwidth.

[0070] The signal waveform transmitted on a carrier can be composed of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource unit can include a symbol period (e.g., the duration of a modulated symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource unit can 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 units received by UE 115 and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity of communication with UE 115.

[0071] One or more numerology for a carrier can be supported, where the numerology can include subcarrier spacing (Δf) and cyclic prefix. A carrier can be divided into one or more bandwidth parts (BWPs) with the same or different numerology. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP of a carrier can be active at a given time, and communication for UE 115 can be restricted to one or more active BWPs.

[0072] The time interval for the base station 105 or UE 115 can be expressed as a multiple of a basic time unit. For example, the basic time unit can refer to T s = 1 / (Δf max ·N f ) seconds of sampling period, where Δf max can represent the maximum supported subcarrier spacing and N f can represent the maximum supported discrete Fourier transform (DFT) size. The time intervals of communication resources can be organized according to radio frames, each radio frame having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0073] Each frame may include a plurality of consecutively numbered sub - frames or time slots, and each sub - frame or time slot may have the same duration. In some examples, a frame (e.g., in the time domain) may be divided into sub - frames, and each sub - frame may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the sub - carrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, a time slot may also be divided into a plurality of mini - time slots each containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f f

[0074] sub - frames, time slots, mini - time slots, or symbols may be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) 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 the TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of short TTIs (sTTIs)).

[0075] Physical channels may be multiplexed on a carrier according to various techniques. For example, time - division multiplexing (TDM) techniques, frequency - division multiplexing (FDM) techniques, or one or more of hybrid TDM - FDM techniques may be used to multiplex physical control channels and physical data channels on a downlink carrier. The control region of a physical control channel (e.g., a control resource set (CORESET)) may be defined by a number of symbol periods and may extend across the system bandwidth of the carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more of the UEs 115 may monitor or search for control regions for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information of a control information format with a given payload size. The search space set may 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.

[0076] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity (e.g., via a carrier) for communicating with the base station 105 and may be associated with an identifier (e.g., physical cell identifier (PCID), virtual cell identifier (VCID), or others) for distinguishing adjacent cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion (e.g., a sector) of the geographic coverage area 110 on which the logical communication entity operates. Depending on various factors such as the capabilities of the base station 105, the range of the cell may vary from a relatively small area (e.g., a structure, a subset of a structure) to a relatively large area. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping with the geographic coverage area 110, and so on.

[0077] Macro cells typically cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow UEs 115 that have subscribed to the services of the network provider supporting the macro cell to have unrestricted access. Compared with macro cells, small cells may be associated with base stations 105 with lower power, and small cells may operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to UEs 115 that have subscribed to the services of the network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed user group (CSG), UEs 115 associated with users in a home or office). The base station 105 may support one or more cells and may also support communication on one or more cells using one or more component carriers.

[0078] 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)), which may provide access for different types of devices.

[0079] In some examples, the base station 105 may be movable and thus provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but 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. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0080] The wireless communication system 100 can support synchronous or asynchronous operations. For synchronous operations, the base stations 105 can have similar frame timings, and transmissions from different base stations 105 can be approximately aligned in time. For asynchronous operations, the base stations 105 can have different frame timings, and in some examples, transmissions from different base stations 105 can be not aligned in time. The techniques described herein can be used for synchronous operations or asynchronous operations.

[0081] Some UEs 115, such as MTC or IoT devices, can be low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with the base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices integrated with sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents the information to a person interacting with the application. Some UEs 115 can be designed to collect information or implement automated behavior of machines or other devices. Examples of applications of 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.

[0082] Some UEs 115 can be configured to operate in power-saving modes, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but not both simultaneously). In some examples, half-duplex communication can be performed at a reduced peak rate. Other energy-saving techniques for UEs 115 include entering a deep sleep power-saving mode when not participating in active communication, operating on a limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of the carrier, or outside the carrier.

[0083] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. The UE 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission-critical functions). Ultra-reliable communication 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.

[0084] In some examples, the UE 115 may also be able to communicate directly with other UEs 115 via 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 communication may be located within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or may be unable to receive transmissions from the base station 105 for other reasons. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0085] In some systems, the D2D communication link 135 may be an example of a communication channel (e.g., a sidelink communication channel) between vehicles (e.g., the 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 scheduling, 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) using vehicle-to-network (V2N) communication, or communicate with the network via one or more network nodes (e.g., the base station 105), or both.

[0086] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an Evolved Packet Core (EPC) or a 5G Core (5GC), which can include at least one control plane entity for managing access and mobility (e.g., Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) and at least one user plane entity for routing packets or interconnecting to external networks (e.g., Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)). The control plane entity can manage Non-Access Stratum (NAS) functions such as mobility, authentication, and bearer management of the UE 115 served by the base station 105 associated with the core network 130. User IP packets can be passed through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can be connected to the network operator IP services 150. The operator IP services 150 can include access to the Internet, intranet, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0087] Some network devices (e.g., base station 105) can include sub-components, such as access network entity 140, which can be an example of an access node controller (ANC). Each access network entity 140 can communicate with the UE 115 through one or more other access network transmission entities 145, which can be referred to as radio heads, intelligent radio heads, or Transmission / Reception Points (TRPs). Each access network transmission entity 145 can include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 can be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., base station 105).

[0088] The wireless communication system 100 can 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 the decimeter band because the wavelength range is approximately from 1 decimeter to 1 meter. UHF waves can be blocked or redirected by buildings and environmental features, but these waves can be sufficient to penetrate structures so that macrocells can serve UEs 115 located indoors. Compared to transmissions at smaller frequencies and longer wavelengths using the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions can be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers).

[0089] The wireless communication system 100 may also operate in the super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz, also known as the centimeter band, or in the 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 communication system 100 may support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the respective devices may be smaller and closer spaced than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the devices. However, the propagation of EHF transmissions may be affected by greater atmospheric attenuation and shorter ranges than SHF or UHF transmissions. The techniques disclosed herein may be used across transmissions using one or more different frequency regions, and the specified use of frequency bands across these frequency regions may vary by country or regulatory body.

[0090] The wireless communication system 100 may use licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may use licensed-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 an unlicensed radio frequency spectrum band, devices such as the base station 105 and the UE 115 may use carrier sensing for collision detection and avoidance. In some examples, operation in an unlicensed band may be based on a carrier aggregation configuration in combination with a component carrier operating in a licensed band (e.g., LAA). Operation in the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer (P2P) transmissions, or device-to-device (D2D) transmissions, among others.

[0091] The base station 105 or the 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 the base station 105 or the UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operation or transmit beamforming 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 the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array with rows and columns of antenna ports that the base station 105 may use to support beamforming for communication with the UE 115. Similarly, the UE 115 may have one or more antenna arrays, which may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0092] The base station 105 or the UE 115 may use MIMO communication to utilize multipath signal propagation and may improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. For example, the multiple signals may be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry 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 for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) and multi-user MIMO (MU-MIMO), where in SU-MIMO, multiple spatial layers are transmitted to the same receiving device, and in MU-MIMO, multiple spatial layers are transmitted to multiple devices.

[0093] 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., base station 105, UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals transmitted via the antenna elements of an antenna array such that signals propagating in a particular direction relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjustment of the signals transmitted via the antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals transmitted via the antenna elements associated with the device. The adjustment associated with each antenna element may be defined by a set of beamforming weights associated with a particular direction (e.g., a particular direction relative to the antenna array of the transmitting device or the receiving device, or a particular direction relative to some other direction).

[0094] The base station 105 or the UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform a beamforming operation for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by the base station 105 multiple times in different directions. For example, the base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used to identify (e.g., by the transmitting device (e.g., base station 105), or by the receiving device (e.g., UE 115)) the beam direction so that the base station 105 can perform subsequent transmissions or receptions.

[0095] Some signals, such as data signals associated with a particular receiving device, can be transmitted by base station 105 in a single beam direction (e.g., the direction associated with the receiving device (e.g., UE 115)). In some examples, the beam direction associated with a transmission along a single beam direction can be determined based on signals that have been transmitted in one or more beam directions. For example, UE 115 can receive one or more of the signals transmitted by base station 105 in different directions and can report to base station 105 an indication of the signal that UE 115 received with the highest signal quality or other acceptable signal quality.

[0096] In some examples, transmissions by a device (e.g., base station 105 or UE 115) can be performed using multiple beam directions, and the device can use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 can report feedback indicating precoding weights for one or more beam directions, and the feedback can correspond to a configured number of beams across the system bandwidth or one or more subbands. Base station 105 can transmit reference signals (e.g., cell-specific reference signal (CRS), channel state information reference signal (CSI-RS)), which can be precoded or not precoded. UE 115 can provide feedback for beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 can employ similar techniques to transmit signals multiple times in different directions (e.g., for identifying beam directions for subsequent transmission or reception by UE 115) or to transmit signals in a single direction (e.g., for transmitting data to a receiving device).

[0097] When receiving various signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, a receiving device (e.g., UE 115) may attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device may attempt multiple receiving directions in the following ways: by receiving via different antenna sub-arrays, by processing received signals according to different antenna sub-arrays, by receiving according to different sets of receive beamforming weights (e.g., different sets of directional listening weights) applied to signals received at multiple antenna elements of the antenna array, or by processing received signals according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of the antenna array; according to different receiving configurations or receiving directions, and any of these ways may be referred to as "listening". In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). This single receiving configuration may be aligned with a beam direction determined based on listening according to different receiving configuration directions (e.g., a beam direction determined to have the highest signal strength, highest SNR, or other acceptable signal quality based on listening according to multiple beam directions).

[0098] Wireless communication system 100 may be a packet-based network operating according to a hierarchical protocol stack. In the user plane, communication at the packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly for communication over logical channels. The medium access control (MAC) layer may perform priority handling and multiplexing of logical channels to transport channels. The MAC layer may 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 may provide establishment, configuration, and maintenance of an RRC connection for a radio bearer supporting user plane data between UE 115 and base station 105 or core network 130. At the physical layer, transport channels may be mapped to physical channels.

[0099] UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid Automatic Repeat reQuest (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data over communication link 125. HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), Forward Error Correction (FEC), and retransmission (e.g., Automatic Repeat reQuest (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, in which the device may provide HARQ feedback for data received in previous symbols in a particular slot in that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0100] In a wireless communication system such as a V2V or V2X communication system, UE 115 may send concurrent messages to other UEs 115 on a sidelink communication channel and to base station 105 on an uplink communication channel. UE 115 may send a report or transmission indicating the ability of UE 115 to perform concurrent transmissions on the sidelink channel and the uplink channel to base station 105. UE 115 may receive a transmission configuration from base station 105 based on the report, where the transmission configuration schedules concurrent sidelink and uplink transmissions within resources shared by the sidelink channel and the uplink channel. Then, UE 115 may send concurrent sidelink and uplink transmissions within the resources shared by the sidelink channel and the uplink channel based on the transmission configuration. Other UEs 115 and one or more base stations 105 may receive the concurrent sidelink and uplink transmissions and may decode different layers of the transmissions based on the received channel quality at the device.

[0101] Figure 2 The illustration shows an example of a wireless communication system 200 that supports concurrent sidelink and uplink transmissions in accordance with various aspects of the present disclosure. In some examples, wireless communication system 200 may implement various aspects of wireless communication system 100. UEs 115-a and 115-b may be examples of UEs 115 as described in the reference Figure 1 above. Base station 105-a may be an example of base station 105 as described in the reference Figure 1 above. UE 115-a may communicate with base station 105-b by receiving and sending signaling on communication channel 205. UE 115-a may communicate with UE 115-b by receiving and sending signaling on sidelink channel 210. UE 115 may be an example of a vehicle in a V2V or V2X wireless communication system.

[0102] UE 115-a can periodically measure the channel quality parameters of communication channel 205 and sidelink channel 210. UE 115-a can measure the SNR of both channels 205 and 210, and can determine that the sidelink channel 210 has a lower SNR or another channel quality measurement. In the case where channel 205 has a relatively higher SNR than sidelink channel 210, this may result in a situation of SNR mismatch. UE 115-a can utilize the SNR mismatch between uplink channel 205 and sidelink channel 210 to send concurrent sidelink and uplink transmissions within the resources shared by sidelink channel 210 and uplink channel 205 to obtain higher spectral efficiency.

[0103] UE 115-a can perform path loss measurements (e.g., average path loss measurements) experienced in sidelink channel 210 during a specific time window T. W UE 115-a can perform this measurement by determining the reference signal received power (RSRP) of sidelink channel 210, and also by receiving sidelink control information (SCI) from a nearby UE (e.g., from UE 115-b) on sidelink channel 210 and decoding the SCI.

[0104] UE 115-b can indicate the intention to perform concurrent sidelink and uplink transmissions to send an indication to base station 105-a. The indication regarding the intention to perform concurrent transmissions can implicitly indicate to the base station the ability to perform concurrent transmissions. In some cases, UE 115-a can also send a capability report 215 to base station 105-a, which indicates the ability of UE 115-a to perform concurrent sidelink and uplink transmissions. In some cases, the indication regarding the intention can be included in the capability report 215.

[0105] UE 115-a can also send a request for sidelink transmission resources to base station 105-a. The request for sidelink transmission resources can be based on sidelink packet priority, buffer status report (BSR), or both. In addition to other path loss reports (e.g., Uu path loss report) to base station 105-a, UE 115-a can also report sidelink quality (e.g., SNR or other measurements) to base station 105-a.

[0106] UE 115-a may also request uplink resources by sending a request to base station 105-a. UE 115-a may also be configured with uplink resources (e.g., based on previous RRC or downlink control information (DCI) signaling). Base station 105-a may send a transmission configuration 220, which may indicate common resources on which base layer 230 encoding for sidelink channel 210 transmission and enhanced layer 235 encoding for uplink communication channel 205 may be performed. The base layer 230 may include sidelink information or data, and the enhanced layer 235 may include uplink information or data. The base layer 230 and the enhanced layer 235 may be assigned the same resources. The base layer 230 may include data of lower quality or lower fidelity than the enhanced layer 235, and the enhanced layer may include data encoded with scalable coding such that the enhanced layer 235 and the base layer 230 can be decoded when transmitted in a high-quality channel, and, due to transmission in a lower-quality channel (e.g., based on the SNR of the channel), the base layer 230 can be decoded and the enhanced layer may not be received.

[0107] The transmission configuration 220 may also include a set of parameters based on the sidelink path quality metric reported by UE 115-a, the uplink path quality metric, the priorities of sidelink communication and uplink communication, and the requested resources. These parameters may include a resource grant, which indicates the resources shared by the uplink channel and the sidelink channel, and the resources may completely or at least partially overlap in time, frequency, or both. These parameters may also include a first modulation and coding scheme (MCS) for sidelink transmission and a second MCS for uplink transmission, and the second MCS may be the same as or different from the first MCS. These parameters may indicate the power allocation β between sidelink transmission and uplink transmission. For example, the power allocation β may indicate the power level for each of the sidelink transmission in the base layer 230 and the uplink transmission in the enhanced layer 235. The power allocation β may be defined such that the power allocation between the sidelink channel and the uplink channel is 0 ≤ β ≤ 1. These parameters may indicate open-loop control parameters (e.g., Po, alpha) for concurrent sidelink and uplink transmission. For example, the open-loop power control parameters may include a Po value and an alpha value.

[0108] UE 115-a can determine the total power budget P based on the open-loop power control parameters received from base station 105-a and the closed-loop power control signaling (e.g., in physical downlink control channel (PDCCH) signaling). UE 115-a can then use the power βP for encoding the base layer 230 and the power (1 - β)P for encoding the uplink enhancement layer 235 of the concurrent transmission 225, and use the MCS parameters indicated for sidelink and uplink to perform the concurrent transmission 225. UE 115-a can send the concurrent transmission 225 of the base layer 230 and the enhancement layer 235 in the same resource, and the concurrent transmission 225 can be received by base station 105-a in channel 205 and also by UE 115-b in the sidelink channel 210.

[0109] UE 115-b can perform decoding of the SCI content to decode the sidelink information of the base layer 230 of the concurrent transmission 225. UE 115-b may not be aware of the existence of the enhancement layer 235, may treat the enhancement layer 235 of the concurrent transmission 225 as noise, or both. Similarly, base station 105-a can decode and obtain the enhancement layer 235 of the concurrent transmission 225 by ignoring or eliminating the sidelink base layer 230. Base station 105-a can know the shared resources allocated for the sidelink channel and the uplink channel and the transmission parameters of the sidelink communication in the base layer 230, and can use these parameters to eliminate the base layer 230 from the received concurrent sidelink and uplink transmissions to decode the enhancement layer 235.

[0110] Figure 3 The illustration shows an example of a process flow 300 that supports concurrent sidelink and uplink transmissions according to aspects of the present disclosure. In some examples, the process flow 300 can implement various aspects of the wireless communication system 100. UE 115-c and 115-d can be examples of UE 115 as described in reference Figure 1 and 2 Base station 105-b can be an example of base station 105 as described in reference Figure 1 and 2 UE 115 can be an example of a vehicle, such as in a V2V or V2X wireless communication system.

[0111] UE 115-c and UE 115-d can communicate via the sidelink communication channel. For example, at 305, UE 115-d can send a sidelink message (e.g., SCI) to UE 115-c. The sidelink reception of UE 115-c can be from a nearby UE, such as UE 115-d. UE 115-c can also communicate with base station 105-b by sending an uplink message and receiving a downlink message from base station 105-b.

[0112] At 310, UE 115-c may determine path loss metrics for the sidelink channel and the uplink channel. UE 115-c may send a first path quality metric for the sidelink channel and a second path quality metric for the uplink channel to the base station 105-b, where the transmission configuration may be based on the first path quality metric and the second path quality metric. Each of the first path quality metric and the second path quality metric may be a path loss metric or another channel measurement.

[0113] At 315, UE 115-c may send a report indicating the ability of UE 115-c to perform concurrent transmissions on the sidelink channel and the uplink channel. UE 115-c may send a report including an indication of the intention to perform concurrent transmissions on the sidelink channel and the uplink channel.

[0114] At 320, UE 115-c may send a resource request. UE 115-c may send a sidelink resource request, where the transmission configuration may be received based on the sidelink resource request. UE 115-c may also send an uplink resource request, where the transmission configuration may be received based on the uplink resource request. These resource requests may be sent jointly or as separate messages.

[0115] At 325, UE 115-c may receive a transmission configuration based on the capability report, where the transmission configuration schedules concurrent sidelink and uplink transmissions within resources shared by the sidelink channel and the uplink channel. UE 115-c may receive a transmission configuration including a resource allocation indicating the resources.
