Resource management techniques for full duplex and half duplex vehicle-to-anything systems

Abstract

Methods, systems, and devices are described for sidelink wireless communications, where a user equipment (UE) that supports full-duplex communications, such as a vehicle UE, can transmit a sidelink control channel during a set of time resources, the sidelink control channel including scheduling information for a subsequent transmission by the UE via a first set of resources. The UE can receive a sidelink control channel from a second UE that can support full-duplex communications or half-duplex communications during the set of time resources. The sidelink control channel can include scheduling information for a subsequent transmission via a second set of time-frequency resources that at least partially overlap with the first set of time-frequency resources. The first UE can determine that a collision will occur and can perform a resource selection procedure, or can transmit a request for the second device to perform a resource selection procedure.

[0004] 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 (e.g., Long Term Evolution (LTE) systems, improved LTE (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems 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 Spread Spectrum Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)).

[0083] Wireless communication systems can support both access links and sidelinks for communication between wireless devices. An access link can refer to a communication link between a UE and a base station. For example, an access link can support uplink signaling, downlink signaling, connection procedures, etc. A sidelink can refer to a communication link similar to that between wireless devices (e.g., a communication link between UEs, or a backhaul communication link between base stations). Note that while the various examples provided herein are discussed with respect to UE sidelink devices, this sidelink technology can be used with any type of wireless communication device (e.g., UE, base station, etc.) that uses sidelink communication. For example, a sidelink can support device-to-device (D2D) communication, V2X and / or vehicle-to-vehicle (V2V) communication, message relay, discovery signaling, beacon signaling, or any combination of these signals or other signals transmitted between devices over the air.

[0084] In some sidelink communication systems (e.g., V2X systems), UEs (e.g., vehicles such as cars, ships, drones, etc.) can use sidelink communication channels (e.g., time-frequency resources allocated for sidelink communication) to send and receive data from other UEs. For example, a UE in a V2X system can send sidelink data to notify other UEs of the vehicle's status, or it can send data to assist vehicles performing certain tasks (e.g., autonomous driving). In some cases, UEs in a V2X system can maintain accurate system information by attempting to receive data packets from each neighboring UE. In some V2X systems, UEs can operate in half-duplex mode when sending and receiving data, where a UE can be configured to send or receive data during a time period. Such V2X systems may include methods for resource management for UEs that enable half-duplex.

[0085] With increasing demand for sidelink resources (e.g., due to increased V2X requirements for autonomous and semi-autonomous vehicles), techniques for efficiently and reliably enhancing the throughput of sidelink channels may be desired. For example, in some V2X systems, UEs can operate in half-duplex mode while transmitting and receiving data. However, incorporating UEs that operate in full-duplex mode while transmitting and receiving data (where full-duplex UEs can be configured to transmit and receive signals during the same time period) can improve spectral efficiency, enabling V2X systems to share large payloads (e.g., sensor message sharing). As the number of full-duplex UEs in a V2X system increases, switching periods may exist, where such systems include both full-duplex and half-duplex UEs (half-duplex UEs). While some systems may include resource management techniques for half-duplex UEs, efficient resource management techniques for full-duplex UEs may be desired due to the introduction of full-duplex UEs, for example, within the V2X system.

[0086] In some examples, wireless communication systems (e.g., V2X) can implement autonomous resource allocation, which may include time-frequency resource reservation techniques. For example, a UE may transmit during a first time period (e.g., during one or more sets of communication resources in time) and reserve several resources for subsequent transmissions during a second time period (e.g., in several future time slots). Transmissions during the first time period may include one or more of transport blocks (TBs), control information, data, etc. The transmitting UE may indicate the reserved resources to other UEs via sidelink control information (SCI) included in the transmissions during the first time period. In some examples, the transmitting UE may send scheduling information indicating the reserved resources to other UEs. In some cases, the reserved resources may be used for retransmission of TBs transmitted during the first time period. In some cases, the reserved resources may be used to transmit new TBs. Such resource reservation methods may include protocols or technologies that support resource reservation and may further support the transition from half-duplex UEs to full-duplex UEs. For example, a V2X system may implement a specific protocol that enables autonomous resource reservation, which may differ from, for example, D2D systems, user-to-user (UU) systems, etc. Therefore, conflicts arising from the autonomous resource reservation involving at least one UE with full-duplex capability can be associated with V2X systems, etc.

[0087] When reserving resources for future transmissions, a UE can consider resource reservations made by other UEs. For example, when a half-duplex UE is not transmitting, it may be listening for transmissions from other UEs (e.g., transmissions including SCI). The half-duplex UE can decode these transmissions and consider them when selecting resources. However, the half-duplex UE may not be aware of reservation information sent by other UEs while it is transmitting. Therefore, a half-duplex UE and another UE in the V2X system may reserve resources for the same future time period. Transmissions from multiple UEs can be frequency-division multiplexed, allowing different UEs to reserve different resources (e.g., sub-channels) during the same time period (e.g., time slot). However, in some cases, the reserved resources may overlap and potentially cause conflicts.

[0088] In some examples, a half-duplex UE can transmit control information including resource reservation information during the same time period (e.g., during a time resource set) that a full-duplex UE transmits control information including reservation information (e.g., scheduling information indicating which time and frequency resources are reserved for subsequent transmissions). Half-duplex and full-duplex UEs can transmit simultaneously and can both reserve frequency resources for the same future time period. In some cases, the reserved frequency resources may overlap (e.g., at least partially overlap, where both full-duplex and half-duplex UEs can reserve at least one frequency resource), potentially leading to collisions. A half-duplex UE may be unaware of the collision because it transmits at the same time as the full-duplex UE (e.g., not listening, operating in transmit mode), but a full-duplex UE may be aware of the collision because it can transmit and receive simultaneously. In some cases, the reserved frequency resources may not overlap, but a half-duplex UE may not receive transmissions from the full-duplex UE during the reserved future time period because the half-duplex UE may also transmit during the reserved future time period and may miss additional resource reservation information. Therefore, technologies for resource management between half-duplex UEs and full-duplex UEs may be desired.

[0089] For example, a full-duplex UE can detect and avoid collisions by performing a resource reselection procedure. For instance, a full-duplex UE performing a resource reselection procedure can choose a new set of resources for reservation, or it can choose some new resources for reservation, to avoid collisions with transmissions from a half-duplex UE. The full-duplex UE can then update its SCI using the updated resource reservation information (e.g., indicating the set of frequency resources to avoid collisions) and can transmit the updated SCI while the half-duplex UE is in receive mode (e.g., operating in a way that allows it to receive signaling instead of transmitting signaling). In such an example, the half-duplex UE may be unaware of the collision and therefore unaware of the selection procedure. In some cases, the full-duplex UE performs reselection based on the full-duplex UE's future transmission priority being less than or equal to the half-duplex UE's future transmission priority. In other cases, the full-duplex UE will perform the selection procedure regardless of future transmission priority.

[0090] In some examples, a full-duplex UE can send a collision indication to a half-duplex UE, requesting the half-duplex UE to perform a resource selection procedure. In some cases, this indication may include the number of physical resource blocks, time slots, or other resources in which collisions occur, or a one-bit indication of future collisions. For example, the indication may transmit the number of resources in which collisions will occur, or it may indicate whether a collision will occur. The half-duplex UE can receive the indication and select a new set of resources for reservation, or it may select some new resources for reservation to avoid collisions with the full-duplex UE. The half-duplex UE can then update its SCI using the updated resource reservation information and can send the updated SCI.

[0091] In some cases, a UE in a full-duplex system may experience high self-interference due to simultaneous transmission and reception (e.g., transmission from the UE at least partially overlaps with reception at the UE). In one aspect, high self-interference may be due to interference from the transmit antenna to the receive antenna. This high self-interference can be mitigated by analog and digital cancellation techniques and is therefore manageable effectively. This allows a full-duplex UE to transmit and receive efficiently during the same time period. There may be situations where a full-duplex UE may not utilize full-duplex capability and may transmit or receive at the same time. For example, a full-duplex UE may experience clutter echoes due to undesirable signal-to-noise ratio (SNR) ratios caused by nearby objects or other UEs at the full-duplex UE in full-duplex mode. A full-duplex UE can determine that its decoding capability may be unreliable based on the SNR and may operate according to reduced full-duplex capability (e.g., sometimes according to half-duplex capability).

[0092] In some examples, a full-duplex UE can transmit within the same time period as a second full-duplex UE, and both UEs can reserve resources for the same future time period. In some cases, the reserved frequency resources may overlap and potentially cause conflicts, or in other cases, the reserved frequency resources may not overlap, but the second UE may, in some situations (e.g., the second full-duplex UE has reduced full-duplex capability, as described herein), not receive transmissions from the first full-duplex UE that are transmitted during the future reserved time period. Therefore, techniques for resource management between full-duplex UEs may be desired.

[0093] For example, a first full-duplex UE and a second full-duplex UE can receive sidelink transmissions, decode SCIs from another full-duplex UE, and infer resource conflicts during future time slots. Additionally, one or both full-duplex UEs can measure SNR based on received transmissions and determine that decoding may be unreliable. In some cases, a full-duplex UE with a lower priority future transmission can perform resource reselection and can choose a new or partially new set of resources to reserve. In some cases, the full-duplex UEs can have equal priorities, and a full-duplex UE with a lower transmission ID (e.g., a smaller transmission ID number) can reselect a new or partially new set of resources to reserve, or both full-duplex UEs can reselect a new or partially new set of resources to reserve. In some cases, both full-duplex UEs can reselect a partially new set of resources. For example, a full-duplex UE with a higher transmission priority can choose odd-numbered resources in the reserved resource set, and a full-duplex UE with a higher transmission priority can choose even-numbered resources in the reserved resource set, and vice versa. In some cases, a full-duplex UE (e.g., a full-duplex UE with higher / lower transmission priority, higher / lower transmission ID, etc.) can send explicit signaling to another full-duplex UE requesting that the other full-duplex UE perform a selection procedure, or instructing the full-duplex UE that is transmitting to perform a selection procedure. For example, a receiving full-duplex UE can receive an indication to select an odd-numbered or even-numbered resource in a reserved resource set, or a new resource set, or it can receive an indication that the full-duplex UE that is transmitting will select an even-numbered or odd-numbered resource in a reserved resource set, or a new resource set.

[0094] The described techniques can support system efficiency, enabling UEs to efficiently reuse or avoid using resources occupied by another UE. The described techniques can support resource reselection and resource management in V2X systems that support one or more of autonomous resource selection, full-duplex UEs, or resource reservation. In this way, full-duplex UEs can transmit over a larger amount of resources, potentially increasing the throughput of the V2X system (compared to other V2X systems without full-duplex UEs). Therefore, the described techniques can allow for greater transmission flexibility at the UE and more efficient use of available resources. Thus, supported techniques can include improved network operation and, in some examples, improved device and network efficiency, among other aspects.

[0095] The various aspects of this disclosure are first described in the context of a wireless communication system. These aspects are further illustrated by segmentation schemes, process flows, apparatus diagrams, system diagrams, and flowcharts relating to resource allocation and segmentation in a wireless system, and are described with reference to the foregoing.

[0096] Figure 1 An example of a wireless communication system 100 supporting resource management techniques for full-duplex and half-duplex V2X systems, according to one or more 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 an LTE network, an LTE-A network, an LTE-A Pro network, or an 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, or communication with low-cost and low-complexity devices, or any combination thereof.

[0097] 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, on which UE 115 and base station 105 can establish one or more communication links 125. Coverage area 110 can be an example of a geographical area where base station 105 and UE 115 can support signal transmission according to one or more wireless access technologies.

[0098] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both 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.

[0099] Base station 105 can communicate with core network 130, communicate with each other, or perform both operations. For example, base station 105 can interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) on backhaul links 120 (e.g., via X2, Xn, or other interfaces), or perform both operations. In some examples, backhaul link 120 can be one or more radio links or may include one or more radio links. UE 115 can communicate with core network 130 via communication link 155.

[0100] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, a base station transceiver, a wireless base station, an access point, a wireless transceiver, a node B, an evolved node B (eNB), a next-generation node B or a gigabit node B (any of which may be referred to as gNB), a home node B, a home evolved node B, or some other suitable term.

[0101] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or user equipment, or some other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, and other examples. UE 115 may also include or 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, among others, UE 115 may include or 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, which, among other examples, may be implemented in various objects such as electrical appliances, vehicles, or instruments.

[0102] The UE 115 described herein is capable of communicating with various types of devices, such as other UEs 115 that can sometimes act as repeaters, as well as base station 105 and network devices, including, among other examples, macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, such as... Figure 1 As shown in the image.

[0103] UE 115 and base station 105 can communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" refers to a set of radio frequency 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 of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating the operation of the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0104] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0105] A carrier can be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the "system bandwidth" of the wireless communication system 100. For example, the carrier bandwidth can be one of several defined bandwidths of a carrier for a specific wireless access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have a hardware configuration that supports communication on a specific carrier bandwidth, or can be configured to support communication on one carrier bandwidth in a set of carrier bandwidths. In some examples, the wireless communication system 100 can 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 can be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0106] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, the two initial operating bands have been designated as frequency range names FR1 (410MHz-7.125GHz) and FR2 (24.25GHz-52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, in various documents and articles, FR1 is generally (interchangeably) referred to as the "below 6GHz" band. Similar naming issues sometimes arise regarding FR2; although it differs from the extremely high frequency (EHF) band (30GHz-300GHz), it is generally (interchangeably) referred to as the "millimeter wave" band in documents and articles, while the EHF band is designated as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0107] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have designated the operating bands for these mid-band frequencies as the frequency range name FR3 (7.125GHz–24.25GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the characteristics of FR1 and / or FR2 to mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation above 52.6GHz. For example, three higher operating frequency bands have been designated as the frequency range names FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0108] In light of the foregoing, unless otherwise specifically stated, it should be understood that when the term "below 6 GHz" is used herein, it can broadly refer to frequencies that are less than 6 GHz, within FR1, or may include intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that when the term "millimeter wave" is used herein, it can broadly refer to frequencies that may include intermediate frequency band frequencies, within FR2, FR4, FR4-a or FR4-1 and / or FR5, or within the EHF band.

[0109] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Spread Spectrum 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 UE 115 receives 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, temporal 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 used for communication with UE 115.

[0110] It can be expressed in a basic unit of time (which can be, for example, 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 The time interval for base station 105 or UE 115 can be represented as a multiple of the maximum supported Discrete Fourier Transform (DFT) size. The time interval for communication resources can be organized based on radio frames, each 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).

[0111] 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., this depends on the length of the cyclic prefix added before 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. Excluding 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.

[0112] A subframe, time slot, micro-time 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)).

[0113] 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 multiple 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 in UE 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 from one or more aggregation levels arranged in a cascaded manner. An 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 may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set used to send control information to a specific UE 115.

[0114] In some examples, base station 105 may be mobile, and therefore 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 wireless access technologies to provide coverage for various geographic coverage areas 110.

[0115] Some UE 115s (e.g., MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated machine-to-machine communication (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 base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices that have integrated sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents it to humans interacting with the application. Some UE 115s can be designed to collect information or automate the behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based billing.

[0116] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via either transmission or reception, rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communication, when operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s 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 carrier's guard band, or outside a carrier.

[0117] 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 (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 push-to-talk, 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 commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0118] In some examples, UE 115 may also communicate directly with other UE 115 on a device-to-device (D2D) (e.g., sidelink) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some examples, multiple groups of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system, wherein each UE 115 transmits to each other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.

[0119] 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, the vehicle may communicate using V2X communication, vehicle-to-vehicle (V2V) communication, or some combination of these. The vehicle may signal information relating to traffic conditions, signal control, weather, safety, emergencies, or any other information relating to the V2X system. In some examples, a vehicle in a V2X system may communicate with roadside infrastructure (such as a roadside unit), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.

[0120] 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 Unit (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function Unit (UPF)) for routing or interconnecting packets to external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to network operator IP service 150. Carrier IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0121] Some network devices (e.g., 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 transport entities 145 (which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP)). Each access network transport 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 individual network devices (e.g., radio headends and ANCs) or incorporated into a single network device (e.g., base station 105).

[0122] Wireless communication system 100 can operate using one or more frequency bands (sometimes in the range of 300 MHz to 300 GHz). In some respects, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can be sufficient to penetrate structures for use in macrocells to provide service to UE 115 located indoors. Compared to the transmission of smaller frequencies and longer waves in the lower frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0123] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency 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 based on carrier aggregation configurations that combine component carriers operating in licensed frequency bands (e.g., LAA). Among other examples, operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, peer-to-peer (P2P) transmissions, or digital-to-digital (D2D) transmissions.

[0124] Base station 105 or UE 115 may be equipped with multiple antennas, which can 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 rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Alternatively or additionally, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0125] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique can be called spatial multiplexing. For example, a transmitting device can transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) (where multiple spatial layers are transmitted to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).

[0126] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105 or UE 115) to form or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0127] As part of beamforming operations, base station 105 or UE 115 may use beam scanning techniques. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Base station 105 may transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, 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 (e.g., by a transmitting device (such as base station 105) or by a receiving device (such as UE 115)) to identify the beam direction for subsequent transmissions or receptions performed by base station 105.

[0128] Base station 105 may transmit signals (e.g., data signals associated with a specific receiving device, such as UE 115) in a single beam direction (e.g., a direction associated with a particular receiving device, such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 that has the highest signal quality or otherwise acceptable signal quality.

[0129] In some examples, multiple beam directions can be used to perform transmissions by a device (e.g., base station 105 or UE 115), and the device can use a combination of digital precoding or radio frequency beamforming to generate combined beams for (e.g., from base station 105 to UE 115) transmissions. UE 115 can report feedback indicating precoding weights for one or more beam directions, and this feedback can correspond to a configured number of beams spanning the system bandwidth or one or more subbands. Base station 105 can transmit reference signals that can be precoded or unprecoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). UE 115 can provide feedback on 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 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify beam directions for subsequent transmissions or receptions by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0130] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the receiving device (e.g., UE 115) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (any of these operations can be referred to as "listening" according to different receiving configurations or receiving directions). In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned to a beam direction determined based on listening in different receiver configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening in multiple beam directions).

[0131] 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 fragmentation and reassembly for transmission over logical channels. The Media Access Control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of RRC connections between the UE 115 and the base station 105 or core network 130 (which supports radio bearers for user plane data). At the physical layer, transport channels can be mapped to physical channels.

[0132] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correct data reception on communication link 125. HARQ can 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 can improve throughput at the MAC layer under poor radio conditions (e.g., low signal and noise conditions). In some examples, the device can support same-slot HARQ feedback, where the device can provide HARQ feedback for data received in a previous symbol within a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0133] In some wireless communication systems (e.g., V2X systems), UE 115 may transmit a Physical Side Link Control Channel (PSCCH) or a Physical Side Link Shared Channel (PSSCH) during a first time period, and may reserve several resources (e.g., RBs) during a second time period (e.g., in several future time slots). Transmissions during the first time period may include one or more of transport blocks (TBs), control information, data, etc. UE 115 may indicate the reserved resources to other UEs 115 via SCIs included in the transmissions during the first time period. In some cases, the reserved resources may be used for retransmission of TBs transmitted during the first time period. In some cases, the reserved resources may be used for transmitting new TBs.

[0134] UE 115 can reserve resources based on reservation information received from one or more other UEs 115. For example, UE 115 can reserve resources separately from other reserved resources. UE 115 in a V2X system can have half-duplex capability, and a half-duplex UE 115 in receive mode (e.g., not transmitting) can monitor transmissions including SCIs from other UEs 115. The half-duplex UE 115 can decode the SCI and consider the decoded scheduling information when selecting resources. However, the half-duplex UE 115 may be unaware of reservation information being transmitted simultaneously with its own transmission. A half-duplex UE 115 and another UE 115 in a V2X system may reserve resources during the same future time period, which could lead to conflicts.

[0135] In some examples, a half-duplex UE 115 may send control information including resource reservation information during the same time period that a full-duplex UE 115 sends, which includes reservation information for the same future time period. In some cases, the reserved frequency resources may overlap and potentially cause collisions. The half-duplex UE 115 may be unaware of the collision because it is transmitting simultaneously with the full-duplex UE (e.g., in transmit mode, not listening, etc.), but the full-duplex UE 115 may be aware of the collision because full-duplex capability includes simultaneous transmission and reception. In some cases, the reserved frequency resources may not overlap, but the half-duplex UE 115 may not receive subsequent transmissions from the full-duplex UE 115 during the reserved future time period and may miss additional resource reservation information.

[0136] In some situations, a full-duplex UE 115 may experience interference conditions (e.g., noisy spurious echoes) and may not utilize full-duplex capability, and may occasionally transmit or receive at one point in time. For example, a full-duplex UE 115 may experience spurious echoes due to undesirable signal-to-noise ratio (SNR) caused by nearby objects or other UEs at the full-duplex UE 115. The full-duplex UE 115 can determine that its decoding capability may be unreliable based on the SNR and can operate according to reduced full-duplex capability (e.g., sometimes according to half-duplex capability).

[0137] In some examples, a full-duplex UE can transmit during the same time period as a second full-duplex UE, and both UEs can reserve resources for the same future time period. In some cases, the reserved frequency resources may overlap and potentially cause conflicts, or in other cases, the reserved frequency resources may not overlap, but the second UE may, in some situations (e.g., if the second full-duplex UE has reduced full-duplex capability, as described herein), not receive transmissions from the first full-duplex UE that are transmitted during the future reserved time period. Therefore, techniques for resource management between full-duplex UEs may be desired.

[0138] UE 115 may include a communication manager 101 that enables UE 115 to reselect resources for transmitting one or more subsequent transmissions of data or control information. A full-duplex UE 115 may transmit concurrently with a half-duplex UE 115 or another full-duplex UE 115 and reserve the same future resources for subsequent transmissions. The communication manager 101 may initiate a selection process to avoid such conflicts. For example, the communication manager 101 may perform a selection process, request other UE 115s to perform resource reselection, and / or may send an indication of a conflict based on one or more of the following: the priority of the subsequent transmission, the transmission ID of the subsequent transmission, or a measured SNR. In some cases, a completely new set of resources may be selected, or a partially new set of resources may be selected.

[0139] Figure 2 Examples of a wireless communication system 200 supporting resource management techniques for full-duplex and half-duplex V2X systems according to one or more aspects of this disclosure are shown. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. In some examples, the wireless communication system 200 may include UE 115-a, UE 115-b, and UE 115-c, which may respectively refer to Figure 1Examples of UE 115 and base station 105 are described. Note that for brevity, communication between three UEs 115 is shown in the wireless communication system 200, and the techniques described herein can be applied to one or more UEs 115 within the system. For example, UE 115-a can communicate with UEs 115-b and UE 115-c simultaneously or at different times, or can communicate with one or the other, for example. Furthermore, sidelink communication techniques can be used for communication of wireless devices other than UEs, such as base station communication (e.g., wireless backhaul links between base stations or TRPs), communication between access points, etc. One or more of the UEs 115 can be implemented in V2X systems, etc., and can be examples of vehicles, autonomous vehicles, drones, or other wireless devices using sidelink communication, as described herein.

[0140] UE 115-a may have full-duplex capability enabled and may be referred to as a full-duplex UE. Full-duplex capability may include the ability to transmit and receive simultaneously. For example, UE 115-a may transmit sidelink transmission 205 to one or both of UE 115-b and UE 115-c during the same time period, and may receive sidelink transmission 205 from either UE 115-d or UE 115-c. UE 115-c may have similar capability and may also be referred to as a full-duplex UE.

[0141] UE 115-b can enable half-duplex capability and can be referred to as a half-duplex UE. Half-duplex capability can include the ability to transmit or receive simultaneously. For example, UE 115-c can send sidelink transmission 205-b to UE 115-a during the same time period that UE 115-a sends sidelink transmission 205-a to UE 115-b. UE 115-b may not receive sidelink transmission 205-a because it is operating in transmit mode with half-duplex capability. For example, when UE 115-b is operating in transmit mode, it may not be operating in receive mode. When UE 115-b is not transmitting, it can operate in receive mode (e.g., listening to or monitoring transmissions).

[0142] In some examples, UE 115-b (which may be referred to as half-duplex UE 115-b operating in half-duplex mode) may transmit sidelink transmission 205-b, including reservation information 210, during the same time period as UE 115-a (which may be referred to as full-duplex UE 115-a operating in full-duplex mode). For example, sidelink transmissions 205-a and 205-b may be transmitted in the same time slot or other time resource unit. The reservation information 210 in sidelink transmissions 205-a and 205-b may include reservations for resources (e.g., frequency resources) during the same subsequent time period. For example, both half-duplex UE 115-b and full-duplex UE 115-a, which are transmitted concurrently, may reserve frequency resources such as physical resource blocks for the same future time period (such as time slots). In some cases, a portion of the reserved frequency resources may overlap, which may lead to conflicts. Half-duplex UE 115-b may not receive the reserved information 210 in the sidelink transmission 205-a and may not detect collisions. However, full-duplex UE 115-a can detect collisions because when sending sidelink transmissions 205-a and 205-b, full-duplex UE 115-a is operating in full-duplex mode with full-duplex capability.

[0143] In some cases, the frequency resources reserved in reservation information 210 may not overlap. However, half-duplex UE 115-b may not receive subsequent transmissions from full-duplex UE 115-a during the subsequent reserved time period because half-duplex UE 115-b may also be transmitting during the subsequent reserved time period (e.g., operating in transmission mode during that time period) and may miss additional resource reservation information. Full-duplex UE 115-a can initiate a resource selection process to avoid such conflicts.

[0144] For example, full-duplex UE 115-a can receive sidelink transmission 205-b and can determine the overlap of reserved resources 230-a in subsequent time slots. Full-duplex UE 115-a can perform a resource selection procedure 220 to avoid conflicts. For example, full-duplex UE 115-a can select a new resource set 230-b for reservation. For example, the reselected resource 230-b may include a completely new resource set or may include a partially new resource set for reservation to avoid conflicts with the reserved resources indicated in sidelink transmission 205-b. Full-duplex UE 115-a can use the updated resource information to send updated reservation information 215 for subsequent sidelink transmissions, and when UE 115-b operates in receive mode 235, the updated reservation information 215 can be sent to UE 115-b. In such an example, half-duplex UE 115-b may be unaware of conflicts and therefore may not be aware of the selection procedure. In some cases, the reservation information 210 sent by UE 115-a may include a transmission ID 220-a associated with a subsequent transmission of UE 115-a, and the reservation information 210 sent by UE 115-b may include a transmission ID 220-b associated with a subsequent transmission of UE 115-b. The transmission ID 220 may indicate the priority of the future transmission. A reselection procedure may be performed by full-duplex UE 115-a based on the transmission ID 220-a of the subsequent transmission (e.g., the priority of the subsequent transmission of UE 115-a) being less than or equal to the transmission ID 220-b of the subsequent transmission associated with half-duplex UE 115-b (e.g., the priority of the subsequent transmission of UE 115-b). In some cases, full-duplex UE 115-a will perform the selection procedure regardless of the transmission ID 220 of the subsequent transmission.

[0145] In some examples, full-duplex UE 115-a can send a collision indication 215 to half-duplex UE 115-b, requesting the half-duplex UE to perform a resource selection procedure while UE 115-b is operating in receive mode. In some cases, the indication may include the number 215-b of physical resource blocks, time slots, or other resources in which the collision occurred, or a one-bit indication 215-a of a future collision, etc. Half-duplex UE 115-b can receive the indication 215 and can select a new set of resources for reservation, or select some new sets of resources for reservation, to avoid collisions with subsequent transmissions of full-duplex UE 115-a. Then, half-duplex UE 115-b can update the reservation information 210 with the updated resource information and can send the updated reservation information 215 to full-duplex UE 115-a.

[0146] In some examples, full-duplex UE 115-a may send a sidelink transmission 205-d to a second full-duplex UE 115-c during the same time period during which UE 115-c sends a sidelink transmission 205-d to full-duplex UE 115-a. Sidelink transmissions 205-c and 205-d may include reservation information 210 for subsequent transmissions by UE 115-a and UE 115-c within the same future time period. The reservation information may include reserved frequency resources, which may overlap and potentially cause conflicts during the reserved time period. In some cases, the reserved frequency resources may not overlap, but in some cases (e.g., where full-duplex UE 115-c may have reduced full-duplex capability, as described herein), full-duplex UE 115-c may not receive transmissions from full-duplex UE 115-a sent during the future reserved time period. Full-duplex UE 115-a or full-duplex UE 115-c or both can initiate a resource selection process to avoid conflicts and ensure reliable decoding.

[0147] For example, full-duplex UEs 115-a and 115-c can receive sidelink transmissions 205-c and 205-d, respectively, and can decode reservation information 210 received from another full-duplex UE. One or both of UEs 115-a and 115-c can infer resource conflicts during future time slots based on the received reservation information 210. Additionally, one or both of full-duplex UEs 115-a and 115-c can measure the SNR based on the received transmissions and can determine that decoding may be unreliable. In some cases, full-duplex UEs 115-a or 115-c, or both, can identify priorities associated with subsequent future transmissions and can perform a resource selection process based on one priority being lower or higher than another. In some cases, the selection process may include selecting a new or partially new set of resources for reservation. In some cases, full-duplex UEs 115-a and 115-c may have equal priorities, and the full-duplex UE 115-a or 115-c with the lower transmission ID may reselect a new or partially new set of resources for reservation. In some cases, both full-duplex UEs 115-a and 115-c may reselect a partially new set of resources. For example, the full-duplex UE 115 with a higher transmission priority may select odd-numbered resources in the reserved resource set, and the full-duplex UE 115 with a higher transmission priority may select even-numbered resources in the reserved resource set, and vice versa. In some cases, a full-duplex UE 115 (e.g., a full-duplex UE 115 with a higher or lower transmission priority, a higher or lower transmission ID, etc.) may send explicit signaling to another full-duplex UE 115 requesting a selection process, or indicating that the full-duplex UE 115 sending the indication will perform the selection process. For example, another full-duplex UE may receive an instruction to select an odd-numbered resource or an even-numbered resource from the reserved resource set, or a new resource set, or it may receive an instruction regarding whether the full-duplex UE making the transmission will select an even-numbered resource or an odd-numbered resource from the reserved resource set, or a new resource set. In such a case, UE 115 can perform a resource selection procedure to avoid conflicts during a future time period.

[0148] Figure 3A and 3B Examples of resource structures 301 and 302 supporting resource management techniques for full-duplex and half-duplex V2X systems according to one or more aspects of this disclosure are shown. In some examples, resource structures 301 and 302 can implement aspects of wireless communication system 100 and wireless communication system 200.

[0149] Resource structures 301 and 302 can illustrate aspects of resource selection before, during, and after resource selection (e.g., a reselection process). Figure 2 As described, a UE can select and reserve resources for transmissions in a wireless communication system (e.g., a V2X system). In some cases, a UE may select resources for transmissions that overlap with those selected by another UE.

[0150] Based on several factors, the UE can determine to reselect reserved resources for future subsequent transmissions. For example, in time slot 1, a first UE can transmit control channel information including scheduling information 305-a, and a second UE can transmit control channel information including scheduling information 305-b, and both can reserve resources 310 (e.g., one or more Physical Resource Blocks (PRBs) in time slot 5) for subsequent time slots. Time slot 5 can include PRB1 to PRBn+1. In some examples, the first UE can reserve a first set of PRBs 310-a in time slot 5, and the second UE can reserve a second set of PRBs 310-b in time slot 5. In some examples, reserved resources 310-c can include one or more of PRBs 1 to PRBn+1, which can be reserved by both the first UE and the second UE, potentially leading to conflicts.

[0151] In some cases, the first UE can determine that: the first UE and the second UE have reserved one or more of PRB1 to PRBn+1, as shown in the reference. Figure 2 The description (e.g., reserved resource 310-c) is as follows. Then, one of the UEs can reselect resource 310 based on determining one or more overlapping frequency resources. In some cases, the first UE can select a new set of PRBs 310-e that was not previously reserved by the first UE. For example, the first UE can initially reserve PRBs 1, 2, 5, and 8 in time slot 5, and the second UE can reserve PRBs 2, 4, and n+1 in time slot 5. The first UE can reselect a new set of resources different from the previously reserved ones, such as PRBs 3, 6, and n. In some cases, the UE can select a partially new set of resources. For example, the first UE can select PRBs 1, 3, and 5. In some cases, the first UE can request the second UE to perform a resource selection procedure. For example, when the second UE is in receive mode 320, the first UE can send an instruction 315. In such cases, the second UE can select a new resource similar to the example provided above (not shown) based on receiving this instruction. The UE performing the reselection process can send an updated SCI (e.g., scheduling information 305-c or 305-d) to indicate the newly selected resource.

[0152] In some cases, the first UE can select an odd-numbered resource from the reserved resources and can instruct the second UE to select an even-numbered resource from the reserved resource set. For example, continuing the previous example, the first UE can reselect PRB 1, 5, and n+1, and the second UE can reselect resources 2, 4, and 8, and vice versa.

[0153] In some cases, reselection is performed based on the priority associated with subsequent transmissions of the UE, the transmission ID associated with the subsequent transmission, the measured SNR at the UE, the sub-channel ID, etc.

[0154] Figure 4 Examples of process flow 400 supporting resource management techniques for full-duplex and half-duplex V2X systems according to one or more aspects of this disclosure are shown. In some examples, process flow 400 may implement aspects of wireless communication system 100 and wireless communication system 200. Process flow 400 may be implemented by UE 115-d, UE 115-e, or any other example of UE 115 as described herein. Alternative examples are possible, some of which may be performed in a different order than described or not at all. In some cases, steps may include additional features not mentioned below, or additional steps may be added.

[0155] At 405, full-duplex UE 115-d may transmit a sidelink control channel or a sidelink data channel, or both, to half-duplex UE 115-e on a resource set (e.g., subchannel / PRB). For example, full-duplex UE 115-d may transmit PSCCH and PSSCH to half-duplex UE 115-e, which may include a first SCI for full-duplex UE 115-d. The first SCI may include resource reservation information indicating resources reserved by UE 115-d for a first subsequent sidelink data channel transmission during a time period. Half-duplex UE 115-e may not receive the first SCI for UE 115-d transmitted on the resource set because at 410, half-duplex UE 115-e may concurrently transmit PSCCH and PSSCH to full-duplex UE 115-d on the same resource set, including a second SCI for UE 115-e. The second SCI may include resource reservation information indicating resources reserved by UE 115-e for transmission of a second subsequent side walkway data channel during the same time period. Full-duplex UE 115-d can receive the second SCI transmitted on the resource set for half-duplex UE 115-e. Therefore, full-duplex UE 115-d and half-duplex UE 115-e can concurrently transmit control information and / or data on the same resource set, but full-duplex UE 115-d can receive the second SCI, while half-duplex UE 115-e may not receive the first SCI.

[0156] At 415, the full-duplex UE 115-d can decode the received SCI and identify the resource reservation information for UE 115-e and the transmission priority information for the first and second subsequent data transmissions. At 420, UE 115-d can determine that the resources reserved by UE 115-e in the second SCI overlap with the resources reserved by UE 115-d in the first SCI, and can infer or determine that a conflict will occur.

[0157] At position 425, full-duplex UE 115-d can send a collision indication to half-duplex UE 115-e, requesting half-duplex UE 115-e to perform a resource selection procedure. In some cases, this indication can be quantified. For example, the indication may include information about the collision, such as how many PRB collisions there are, which PRB collisions, which time slots contain the collision, or indications of other resources in which the collision occurred. In some examples, the indication is a bit used to indicate that the collision is scheduled to occur during a future time period. Full-duplex UE 115-d may transmit during the time period that half-duplex UE 115-e is listening for (e.g., not transmitting, operating in receive mode, etc.), and half-duplex UE 115-e may receive the indication. In some cases, full-duplex UE 115-d sends the collision indication based on the transmission priority of the first subsequent data channel transmission being greater than or equal to that of the second subsequent data channel transmission. In some cases, full-duplex UE 115-d will send the collision indication regardless of future transmission priority.

[0158] At 430, the half-duplex UE 115-e can select a new set of resources for reservation, or select some new resources (e.g., a partially new set of resources) for reservation, based on a received instruction, to avoid conflicts with the full-duplex UE 115-d. The half-duplex UE 115-e can update its SCI at 440 using the updated resource reservation information based on the execution of a resource selection procedure, and can send the updated SCI to the full-duplex UE 115-d.

[0159] At point 435, the full-duplex UE 115-d can detect and avoid conflicts by performing a resource selection procedure. For example, the full-duplex UE 115-d can select a new set of resources for reservation or can select some new resources for the first subsequent data channel transmission to avoid conflicts with the second subsequent data channel transmission. At point 440, the full-duplex UE 115-d can update its SCI using the updated resource reservation information and can send the updated SCI to the half-duplex UE 115-e. In such an example, the half-duplex UE 115-e may be unaware of the conflict and therefore unaware of the selection procedure. In some cases, the full-duplex UE 115-d performs reselection based on the transmission priority of the first subsequent data channel transmission being less than or equal to that of the second subsequent data channel transmission. In some cases, the full-duplex UE 115-d will perform the selection procedure regardless of future transmission priorities.

[0160] Figure 5Examples of process flow 500 supporting resource management techniques for full-duplex and half-duplex V2X systems according to one or more aspects of this disclosure are shown. In some examples, process flow 500 may implement aspects of wireless communication system 100 or wireless communication system 200. Process flow 500 may be implemented by UE 115-f, UE 115-g, or any other example of UE 115 as described herein. Alternative examples are possible, some of which may be performed in a different order than described or not at all. In some cases, steps may include additional features not mentioned below, or additional steps may be added.

[0161] At 505, full-duplex UE 115-f can transmit a sidelink control channel or a sidelink data channel, or both, to full-duplex UE 115-g on a resource set (e.g., subchannel / PRB). For example, full-duplex UE 115-f can transmit PSCCH and PSSCH to full-duplex UE 115-g, which may include a first SCI for full-duplex UE 115-f. The first SCI may include resource reservation information indicating resources reserved by UE 115-f for a first subsequent sidelink data channel transmission during a time period. Full-duplex UE 115-g can receive the first SCI transmitted on the resource set for UE 115-f and can concurrently transmit PSCCH and PSSCH to full-duplex UE 115-f on the same resource set including a second SCI for UE 115-g. The second SCI may include resource reservation information indicating resources reserved by UE 115-g for transmission of a second subsequent side walkway data channel during the same time period. Full-duplex UE 115-f can receive the second SCI transmitted on the resource set for full-duplex UE 115-g. Therefore, full-duplex UE 115-f and full-duplex UE 115-g can concurrently transmit and receive control information and / or data on the same resource set.

[0162] At point 510, full-duplex UE 115-f and UE 115-g can decode the received SCI and can identify resource reservation information for UE 115-g and UE 115-f respectively. UE 115-f can determine that the resources reserved by UE 115-g in the second SCI overlap with the resources reserved by UE 115-f in the first SCI, and can infer or determine that a conflict will occur, and vice versa. At point 515, UE 115-f can determine the transmission priority associated with the transmission of the second subsequent side walkway data channel, and can determine that it is higher, lower, or equal to the transmission priority associated with the transmission of the first subsequent data channel. Alternatively, UE 115-g can determine the transmission priority associated with the transmission of the first subsequent side walkway data channel, and can determine that it is higher, lower, or equal to the transmission priority associated with the transmission of the second subsequent data channel. In some cases, transmission priorities may be equal, and UE 115-f may also determine that the transmission ID associated with the second subsequent data channel transmission is higher or lower than the transmission ID associated with the first subsequent data channel transmission, or UE 115-g may also determine that the transmission ID associated with the first subsequent data channel transmission is higher or lower than the transmission ID associated with the second subsequent data channel transmission, or both.

[0163] At position 520, UE 115-f and UE 115-g can each measure the SNR of the received PSCCH and PSSCH, and UE 115-f and UE 115-g, or both, can determine that the corresponding SNR meets a threshold. For example, UE 115-f or UE 115-g, or both, can determine that the SNR is too low or too high for reliable decoding. In some cases, UE 115-f or UE 115-g, or both, can determine that the SNR does not meet the threshold.

[0164] In some cases, at 525, UE 115-f can send a conflict indication to UE 115-g. For example, UE 115-f can determine that the transmission priority associated with a first subsequent data channel transmission is lower than the transmission priority associated with a second subsequent data channel transmission, and can send an indication to UE 115-g that it will perform a resource selection procedure (e.g., explicit signaling). UE 115-f can indicate that it will select a new set of resources or a partially new set of resources that includes some of the previously reserved resources. If UE 115-f will select a partially new set of resources, UE 115-g can also select a partially new set of resources based on this indication to avoid conflicts. For example, UE 115-f can indicate that it will select odd-numbered resources in the reserved resource set, and based on this indication, UE 115-f can select even-numbered resources in the reserved resource set, and vice versa. In some cases, UE 115-f may send this indication when it determines that the transmission priority associated with the first subsequent data channel transmission is higher than the transmission priority associated with the second subsequent data channel transmission.

[0165] In some examples, UE 115-f may determine that the transmission priority associated with the first subsequent data channel transmission may be higher than the transmission priority associated with the second subsequent data channel transmission, and may send a conflict indication to explicitly request UE 115-g to perform a selection process. For example, UE 115-f may request that UE 115-g select a new resource set or a partially new resource set that includes some of the previously reserved resources to avoid a conflict. When instructing UE 115-g to select a partially new resource set, UE 115-f may also select the partially new resource set based on that indication. For example, UE 115-f may instruct UE 115-g to select an odd number of resources from the reserved resource set, and based on that indication, UE 115-f may select an even number of resources from the reserved resource set, and vice versa. In some cases, UE 115-f may send a request when it determines that the transmission priority associated with the first subsequent data channel transmission is lower than the transmission priority associated with the second subsequent data channel transmission.

[0166] In some examples, UE 115-f may determine that the transmission priority associated with the first subsequent data channel transmission may be equal to the transmission priority associated with the second subsequent data channel transmission, and may send a conflict indication to another UE 115-g based on determining that the transmission ID associated with the second subsequent data channel transmission is higher or lower than the transmission ID associated with the first subsequent data channel transmission. The conflict indication requests UE 115-g to perform a selection procedure or instructs UE 115-f to perform a selection procedure.

[0167] At point 530, UE 115-f can perform a resource selection procedure. For example, UE 115-f can determine at point 515 that the transmission priority associated with the first subsequent data channel transmission is lower than the transmission priority associated with the second subsequent data channel transmission, and can select a new set of resources to avoid conflicts with reserved resources for the second subsequent data channel transmission. In such a case, UE 115-g can transmit the second subsequent data channel transmission on resources reserved in the second SCI. In some cases, UE 115-g can determine that the transmission priority associated with the second subsequent data channel transmission is lower than the transmission priority associated with the first subsequent data channel transmission, and can alternatively select a new set of resources to avoid conflicts with reserved resources for the first subsequent data channel transmission.

[0168] In some examples, at 530, a lower-priority UE (e.g., UE 115-f or UE 115-g) can select a portion of the new resource set as well as some resources from previously reserved resources. For example, UE 115-f or UE 115-g may determine that one or more resource blocks reserved via a first SCI overlap with one or more resource blocks reserved via a second SCI, and may reselect the overlapping resource blocks while retaining the non-overlapping reserved resource blocks. In some cases, a reselection process is performed based on whether the measured SNR of UE 115-f or UE 115-g meets a threshold (e.g., the SNR is too high or too low for reliable decoding). For example, the SNR measured at UE 115-g may meet a threshold, and UE 115-g may determine to perform a reselection process to avoid conflicts.

[0169] In some examples, at 530, UE 115 can have the same priority and can perform a reselection process based on the transmission IDs of the first and second subsequent data channel transmissions. For example, UE 115-f can determine at 515 that the transmission ID associated with the first subsequent data channel transmission is lower than the transmission ID associated with the second subsequent data channel transmission, and can select a new set of resources to avoid conflicts with reserved resources for the second subsequent data channel transmission, and vice versa. In some examples, the UE associated with the lower transmission ID can select a partially new set of resources. In some cases, the reserved resources and the reselected resources can be randomized by the UE. In some cases, the reserved resources and the reselected resources can be based on whether the resource number is odd or even. For example, UE 115 associated with the higher transmission ID can reselect odd-numbered resources, while UE 115 associated with the lower transmission ID can reselect even-numbered resources, and vice versa. In some examples, such a reselection can be based on the transmission priority associated with UE 115.

[0187] Figure 8 A block diagram 800 of a communication manager 805 supporting resource management techniques for full-duplex and half-duplex V2X systems, according to one or more aspects of this disclosure, is shown. The communication manager 805 may be an example of aspects of the communication manager 615, communication manager 715, or communication manager 910 described herein.

[0199] In some cases, the indication includes the number of resources in which the first time-frequency resource set and the second time-frequency resource set overlap.

[0200] The full-duplex resource selection manager 825 can perform a resource selection process based on determining that the first time-frequency resource set and the second time-frequency resource set at least partially overlap.

[0202] In some examples, a third time-frequency resource set, different from the second time-frequency resource set, is selected, wherein the third time-frequency resource set includes a subset of the first time-frequency resource set based on a threshold satisfied by the signal-to-noise ratio of the received second-side link control channel.

[0203] In some examples, the full-duplex resource selection manager 825 may select a third time-frequency resource set that is different from the second time-frequency resource set based on the determination that a second transmission identifier associated with the second side cross-link data channel is greater than a first transmission identifier associated with the first side cross-link data channel.

[0216] Figure 9 A diagram of a system 900 including device 905 supporting resource management technologies for full-duplex and half-duplex V2X systems is shown, according to one or more aspects of this disclosure. Device 905 may be an example of device 605, device 705, or UE 115 as described herein, or a component including device 605, device 705, or UE 115. Device 905 may include components for bidirectional voice and data communication, including components for transmitting and receiving communications, including a communication manager 910, an I / O controller 915, a transceiver 920, an antenna 925, a memory 930, and a processor 940. These components may communicate electronically via one or more buses (e.g., bus 945).

[0217] The communication manager 910 can perform the following operations: transmit a first-side hop control channel during a time resource set, the first-side hop control channel including scheduling information for the device to transmit a first-side hop data channel via a first time-frequency resource set; receive a second-side hop control channel from a second device during a time resource set, the second-side hop control channel including scheduling information for the second device to transmit a second-side hop data channel via a second time-frequency resource set; determine that the first time-frequency resource set and the second time-frequency resource set at least partially overlap; and perform a resource selection process based on the determination that the first time-frequency resource set and the second time-frequency resource set at least partially overlap.

[0218] The I / O controller 915 can manage input and output signals for device 905. The I / O controller 915 can also manage peripheral devices not integrated into device 905. In some cases, the I / O controller 915 can represent a physical connection or port to an external peripheral device. In some cases, the I / O controller 915 can utilize, for example... This can be an operating system such as a modem, keyboard, mouse, touchscreen, or similar device, or an interface with such devices. In some cases, the I / O controller 915 may be implemented as part of a processor. In some cases, a user may interact with the device 905 via the I / O controller 915 or via hardware components controlled by the I / O controller 915.

For example, transceiver 920 can represent a wireless transceiver and can communicate bidirectionally with another wireless transceiver. Transceiver 920 may also include a modem for modulating packets and providing the modulated packets to the antenna for transmission, and for demodulating packets received from the antenna.

Memory 930 may store computer-readable, computer-executable code 935, which includes instructions that, when executed, cause the processor to perform the various functions described herein. In some cases, in addition to this, memory 930 may also contain a basic I / O system (BIOS) that controls basic hardware or software operations, such as interaction with peripheral components or devices.

[0222] Processor 940 may include intelligent hardware devices (e.g., general-purpose processors, DSPs, CPUs, microcontrollers, ASICs, FPGAs, programmable logic devices, discrete gate or transistor logic components, discrete hardware components, or any combination thereof). In some cases, processor 940 may be configured to use a memory controller to operate a memory array. In other cases, the memory controller may be integrated into processor 940. Processor 90 may be configured to execute computer-readable instructions stored in memory (e.g., memory 930) to cause device 905 to perform various functions (e.g., functions or tasks supporting resource management techniques for full-duplex and half-duplex V2X systems).

[0223] Code 935 may include instructions for implementing various aspects of this disclosure, including instructions for supporting wireless communication. Code 935 may be stored in a non-transitory computer-readable medium (e.g., system memory or other types of memory). In some cases, code 935 may not be directly executable by processor 940, but may cause a computer (e.g., when compiled and executed) to perform the functions described herein.

[0224] The actions performed by the processor 940, memory 930, I / O controller 915, communication manager 910, transceiver 920, and antenna 925, as described herein, can be implemented to achieve one or more potential implementations. One implementation may allow device 905 to save power and increase battery life by performing a resource selection process. Another implementation may provide improved data throughput and user experience at device 905, enabling full-duplex capability.
