The method may include the steps of: determining a priority associated with sidelink (SL) transmission; receiving information about an SL threshold associated with uplink (UL) transmission from a base station; and performing one of the SL transmission and the UL transmission based on the priority associated with the SL transmission and the SL threshold.

Description

Technical Field

[0001] The present disclosure relates to a wireless communication system. Background Art

[0002] Sidelink (SL) communication is a communication scheme in which a direct link is established between user equipments (UEs) and the UEs directly exchange voice and data with each other without the intervention of an evolved Node B (eNB). SL communication is being considered as a solution to eNB overhead caused by rapid growth of data traffic.

[0003] V2X (Vehicle-to-Everything) refers to a communication technology in which a vehicle exchanges information with other vehicles, pedestrians, objects equipped with infrastructure, etc. V2X can be classified into four types such as V2V (Vehicle-to-Vehicle), V2I (Vehicle-to-Infrastructure), V2N (Vehicle-to-Network), and V2P (Vehicle-to-Pedestrian). V2X communication can be provided through a PC5 interface and / or a Uu interface.

[0004] In addition, since more and more communication devices require a large communication capacity, enhanced mobile broadband communication is required as compared with traditional radio access technology (RAT). Accordingly, a communication system design for UEs or services sensitive to reliability and latency has also been discussed, and a next-generation radio access technology considering enhanced mobile broadband communication, massive MTC, and ultra-reliable low-latency communication (URLLC) can be referred to as a new RAT (radio access technology) or NR (New Radio).

[0005] Figure 1 is a diagram for describing NR-based V2X communication as compared with V2X communication based on a RAT used before NR. Figure 1 Embodiments of can be combined with various embodiments of the present disclosure.

[0006] Regarding V2X communication, when discussing a RAT used before NR, a scheme of providing a security service based on V2X messages such as BSM (Basic Safety Message), CAM (Cooperative Awareness Message), and DENM (Decentralized Environment Notification Message) has been focused on. V2X messages may include location information, dynamic information, attribute information, etc. For example, a UE may transmit a periodic message type CAM and / or an event-triggered message type DENM to another UE.

[0007] For example, the CAM may include dynamic state information of the vehicle such as direction and speed, static data of the vehicle such as size, and basic vehicle information such as external lighting status, route details, etc. For example, the UE may broadcast the CAM, and the latency of the CAM may be less than 100 ms. For example, the UE may generate a DENM and send it to another UE in the event of an unexpected situation such as a vehicle failure, an accident, etc. For example, all vehicles within the transmission range of the UE can receive the CAM and / or the DENM. In this case, the priority of the DENM may be higher than that of the CAM.

[0008] Thereafter, regarding V2X communication, various V2X scenarios have been proposed in NR. For example, these various V2X scenarios may include vehicle platooning, advanced driving, extended sensors, remote driving, etc.

[0009] For example, based on vehicle platooning, vehicles can move together by dynamically forming groups. For example, in order to perform platooning operations based on vehicle formation, the vehicles belonging to the group can receive periodic data from the leading vehicle. For example, the vehicles belonging to the group can reduce or increase the interval between vehicles by using the periodic data.

[0010] For example, based on advanced driving, the vehicle can be semi-automatic or fully automatic. For example, each vehicle can adjust its trajectory or maneuver based on data obtained from local sensors of nearby vehicles and / or nearby logical entities. Additionally, for example, each vehicle can share its driving intention with nearby vehicles.

[0011] For example, based on extended sensors, raw data, processed data, or real-time video data obtained through local sensors can be exchanged between vehicles, logical entities, UEs of pedestrians, and / or V2X application servers. Therefore, for example, compared with the environment where detection is performed using self-sensors, the vehicle can identify an environment with further improvement.

[0012] For example, based on remote driving, for a person who cannot drive or a remote vehicle in a dangerous environment, a remote driver or a V2X application can operate or control the remote vehicle. For example, if the route is predictable, such as public transportation, cloud-based driving can be used to operate or control the remote vehicle. Additionally, for example, remote driving can consider accessing a cloud-based backend service platform.

[0013] In addition, in NR-based V2X communication, solutions for specifying service requirements for various V2X scenarios such as vehicle platooning, advanced driving, extended sensors, remote driving, etc. have been discussed. Summary of the Invention

[0039] In this specification, "A or B" may mean "only A", "only B", or "both A and B". In other words, in this specification, "A or B" may be interpreted as "A and / or B". For example, in this specification, "A, B, or C" may mean "only A", "only B", "only C", or "any combination of A, B, and C".

[0040] In this specification, the slash ( / ) or comma used may mean "and / or". For example, "A / B" may mean "A and / or B". Therefore, "A / B" may mean "only A", "only B", or "both A and B". For example, "A, B, C" may mean "A, B, or C".

[0044] The technical features described separately in one of the drawings in this specification may be implemented separately or may be implemented simultaneously.

[0045] The techniques described below can be used in various wireless communication systems such as code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), etc. CDMA can be implemented using radio technologies such as Universal Terrestrial Radio Access (UTRA) or CDMA-2000. TDMA can be implemented using radio technologies such as Global System for Mobile Communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data Rate for GSM Evolution (EDGE). OFDMA can be implemented using radio technologies such as Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Evolved UTRA (E-UTRA), etc. IEEE 802.16m is an evolved version of IEEE 802.16e and provides backward compatibility for systems based on IEEE 802.16e. UTRA is part of the Universal Mobile Telecommunications System (UMTS). The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is part of the Evolved UMTS (E-UMTS) that uses E-UTRA. 3GPP LTE uses OFDMA in the downlink and SC-FDMA in the uplink. Long Term Evolution-Advanced (LTE-A) is an evolution of LTE.

[0046] 5G NR is a subsequent technology to LTE-A corresponding to a new and innovative mobile communication system with characteristics such as high performance, low latency, and high availability. 5G NR can utilize resources of all available spectrums, including low-frequency bands below 1 GHz, intermediate frequency bands from 1 GHz to 10 GHz, and high frequencies (millimeter waves) above 24 GHz.

[0047] For clear description, the following description will mainly focus on LTE-A or 5G NR. However, the technical features according to the embodiments of the present disclosure are not limited thereto.

[0048] Figure 2 Shows the structure of an NR system based on an embodiment of the present disclosure. Figure 2 Embodiments of can be combined with various embodiments of the present disclosure.

[0049] Refer to Figure 2 , the next-generation radio access network (NG-RAN) may include a BS20 that provides user-plane and control-plane protocol termination to the UE 10. For example, BS20 may include a next-generation node B (gNB) and / or an evolved node B (eNB). For example, UE10 may be fixed or mobile and may be referred to by other terms such as a mobile station (MS), a user terminal (UT), a subscriber station (SS), a mobile terminal (MT), a wireless device, etc. For example, a BS may be referred to as a fixed station communicating with the UE 10 and may be referred to by other terms such as a base transceiver system (BTS), an access point (AP), etc.

[0050] Figure 2 Embodiments of illustrate only the case including a gNB. BS20s may be interconnected via the Xn interface. BS20s may be interconnected via the fifth-generation (5G) core network (5GC) and the NG interface. More specifically, BS 20 may be connected to the access and mobility management function (AMF) 30 via the NG-C interface and may be connected to the user-plane function (UPF) 30 via the NG-U interface.

[0051] Figure 3 Shows the functional division between the NG-RAN and the 5GC based on an embodiment of the present disclosure. Figure 3 Examples of can be combined with various examples of the present disclosure.

[0052] Refer to Figure 3, the gNB can provide functions such as inter-cell radio resource management (inter-cell RRM), radio bearer (RB) control, connection mobility control, radio access control, measurement configuration and regulation, dynamic resource allocation, etc. The AMF can provide functions such as non-access stratum (NAS) security, idle state mobility handling, etc. The UPF can provide functions such as mobility anchoring, protocol data unit (PDU) processing, etc. The session management function (SMF) can provide functions such as user equipment (UE) Internet protocol (IP) address allocation, PDU session control, etc.

[0053] The radio interface protocol layers between the UE and the network can be classified into a first layer (L1), a second layer (L2), and a third layer (L3) based on the lower three layers of the well-known Open Systems Interconnection (OSI) model in a communication system. Here, the physical (PHY) layer belonging to the first layer provides an information transmission service using a physical channel, and the radio resource control (RRC) layer located in the third layer controls the radio resources between the UE and the network. To this end, the RRC layer exchanges RRC messages between the UE and the BS layer.

[0054] Figure 4 Shows a radio protocol architecture based on an embodiment of the present disclosure. Figure 4 Embodiments of can be combined with various embodiments of the present disclosure. Specifically, Figure 4 (a) in shows a radio protocol architecture for the user plane, and Figure 4 (b) in shows a radio protocol architecture for the control plane. The user plane corresponds to a protocol stack for user data transmission, and the control plane corresponds to a protocol stack for control signal transmission.

[0055] Referring to Figure 4 , the physical layer provides an information transfer service to the upper layer through a physical channel. The physical layer is connected to the medium access control (MAC) layer, which is the upper layer of the physical layer, through a transport channel. Data is transferred between the MAC layer and the physical layer through the transport channel. The transport channel is classified according to how data is transmitted through the radio interface and what characteristics of the data are transmitted.

[0056] Data is transferred through a physical channel between different PHY layers (i.e., the PHY layer of the transmitter and the PHY layer of the receiver). The physical channel can be modulated using an orthogonal frequency division multiplexing (OFDM) scheme, and the physical channel uses time and frequency as radio resources.

[0057] The MAC layer provides services to the Radio Link Control (RLC) layer via logical channels, and the RLC layer is the higher layer of the MAC layer. The MAC layer provides the function of mapping multiple logical channels to multiple transport channels. The MAC layer also provides the function of logical channel multiplexing by mapping multiple logical channels to a single transport channel. The MAC layer provides data transmission services via logical channels.

[0058] The RLC layer performs concatenation, segmentation, and reassembly of Radio Link Control Service Data Units (RLC SDUs). To ensure different Quality of Service (QoS) required by radio bearers (RBs), the RLC layer provides three types of operation modes, namely, Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). AM RLC provides error correction through Automatic Repeat reQuest (ARQ).

[0059] The Radio Resource Control (RRC) layer is only defined in the control plane. Moreover, the RRC layer performs the function of controlling physical channels, transport channels, and logical channels associated with the configuration, reconfiguration, and release of radio bearers. An RB refers to the logical path provided by the first layer (i.e., the PHY layer) and the second layer (i.e., the MAC layer, RLC layer, and PDCP layer) to transmit data between the UE and the network.

[0060] The functions of the Packet Data Convergence Protocol (PDCP) in the user plane include the transmission, header compression, and encryption of user data. The functions of the Packet Data Convergence Protocol (PDCP) in the control plane include the transmission and encryption / integrity protection of control plane data.

[0061] The Service Data Adaptation Protocol (SDAP) layer is only defined in the user plane. The SDAP layer performs the mapping between Quality of Service (QoS) flows and Data Radio Bearers (DRBs) and the QoS Flow ID (QFI) marking in both DL packets and UL packets.

[0062] The configuration of an RB refers to the process of specifying radio protocol layers and channel attributes to provide a specific service and determining the corresponding detailed parameters and operation methods. An RB can then be classified into two types, namely, Signaling Radio Bearer (SRB) and Data Radio Bearer (DRB). The SRB is used as the path for sending RRC messages in the control plane, and the DRB is used as the path for sending user data in the user plane.

[0063] When the RRC connection is established between the RRC layer of the UE and the RRC layer of the E-UTRAN, the UE is in the RRC connected (RRC_CONNECTED) state. Otherwise, the UE can be in the RRC idle (RRC_IDLE) state. In the case of NR, an RRC inactive (RRC_INACTIVE) state is additionally defined, and a UE in the RRC_INACTIVE state can maintain its connection with the core network while releasing its connection with the BS.

[0064] The downlink transport channels for sending (or transmitting) data from the network to the UE include the broadcast channel (BCH) for sending system information and the downlink shared channel (SCH) for sending other user services or control messages. The services or control messages for downlink multicast or broadcast services can be sent via the downlink SCH or can be sent via a separate downlink multicast channel (MCH). In addition, the uplink transport channels for sending (or transmitting) data from the UE to the network include the random access channel (RACH) for sending initial control messages and the uplink shared channel (SCH) for sending other user services or control messages.

[0065] The logical channels that exist at a layer higher than the transport channels and are mapped to the transport channels can include the broadcast control channel (BCCH), the paging control channel (PCCH), the common control channel (CCCH), the multicast control channel (MCCH), the multicast traffic channel (MTCH), etc.

[0066] The physical channel is configured by multiple OFDM symbols in the time domain and multiple subcarriers in the frequency domain. A subframe is configured by multiple OFDM symbols in the time domain. A resource block is configured by multiple subcarriers and multiple OFDM symbols in a resource allocation unit. Additionally, each subframe can use a specific subcarrier of a specific OFDM symbol (e.g., the first OFDM symbol) of the corresponding subframe of the physical downlink control channel (PDCCH), i.e., the L1 / L2 control channel. The transmission time interval (TTI) refers to the unit time for sending a subframe.

[0067] Figure 5 The structure of an NR system according to an embodiment of the present disclosure is shown. Figure 5 The embodiments of can be combined with various embodiments of the present disclosure.

[0068] Refer to Figure 5, in NR, radio frames can be used to perform uplink and downlink transmissions. The length of a radio frame is 10 ms and can be defined as consisting of two half-frames (HFs). A half-frame can include five 1-ms sub-frames (SFs). A sub-frame (SF) can be divided into one or more time slots, and the number of time slots within a sub-frame can be determined based on the subcarrier spacing (SCS). Each time slot can include 12 or 14 OFDM(A) symbols according to the cyclic prefix (CP).

[0069] In the case of using normal CP, each time slot can include 14 symbols. In the case of using extended CP, each time slot can include 12 symbols. Herein, a symbol can include an OFDM symbol (or CP-OFDM symbol) and a single-carrier FDMA (SC-FDMA) symbol (or discrete Fourier transform spread OFDM (DFT-s-OFDM) symbol).

[0070] For example, Table 1 below shows the number of time slots per symbol (N slot symb ), the number of time slots per frame (N frame,u slot ), and the number of time slots per sub-frame (N subframe,u slot ) based on the SCS setting (μ) in the case of using normal CP.

[0071] [Table 1]

[0072] <![CDATA[SCS(15*2 u )]]> <![CDATA[N slot symb > <![CDATA[N frame,u slot > <![CDATA[N subframe,u slot > 15 KHz (u = 0) 14 10 1 30 KHz (u = 1) 14 20 2 60 KHz (u = 2) 14 40 4 120 KHz (u = 3) 14 80 8 240 KHz (u = 4) 14 160 16

[0073] Table 2 shows examples of the number of symbols per time slot, the number of time slots per frame, and the number of time slots per sub-frame based on the SCS in the case of using extended CP.

[0074] [Table 2]

[0075] <![CDATA[SCS(15*2 u )]]> <![CDATA[N slot symb > <![CDATA[N frame,u slot > <![CDATA[N subframe,u slot > 60 KHz (u = 2) 12 40 4

[0076] In an NR system, the OFDM(A) parameter sets (e.g., SCS, CP length, etc.) between multiple cells integrated into one UE can be configured differently. Therefore, the (absolute time) duration (or interval) of a time resource (e.g., sub-frame, time slot, or TTI) (collectively referred to as a time unit (TU) for simplicity) consisting of the same number of symbols can be configured differently in the integrated cells.

[0077] In NR, multiple parameter sets or SCSs can be supported to support various 5G services. For example, in the case of an SCS of 15 kHz, a wide range of traditional cellular bands can be supported, and in the case of an SCS of 30 kHz / 60 kHz, dense urban areas, lower latency, and wider carrier bandwidth can be supported. In the case of an SCS of 60 kHz or higher, in order to overcome phase noise, a bandwidth greater than 24.25 GHz can be used.

[0078] NR bands can be defined as two different types of frequency ranges. The two different types of frequency ranges can be FR1 and FR2. The values of the frequency ranges can change (or vary). For example, the two different types of frequency ranges can be as shown in Table 3 below. Among the frequency ranges used in the NR system, FR1 can mean "the range below 6 GHz", and FR2 can mean "the range above 6 GHz", and can also be referred to as millimeter wave (mmW).

[0079] [Table 3]

[0080] Frequency range specification Corresponding frequency range Subcarrier spacing (SCS) FR1 450 MHz - 6000 MHz 15, 30, 60 kHz FR2 24250 MHz - 52600 MHz 60, 120, 240 kHz

[0081] As described above, the values of the frequency ranges in the NR system can change (or vary). For example, as shown in Table 4 below, FR1 can include a bandwidth in the range of 410 MHz to 7125 MHz. More specifically, FR1 can include bands at 6 GHz (or 5850, 5900, 5925 MHz, etc.) and higher. For example, the bands at 6 GHz (or 5850, 5900, 5925 MHz, etc.) included in FR1 can include unlicensed bands. The unlicensed bands can be used for various purposes. For example, the unlicensed bands are used for vehicle-specific communication (e.g., autonomous driving).

[0082] [Table 4]

[0083] Frequency range specification Corresponding frequency range Subcarrier spacing (SCS) FR1 410 MHz - 7125 MHz 15, 30, 60 kHz FR2 24250 MHz - 52600 MHz 60, 120, 240 kHz

[0084] Figure 6 The structure of a time slot of an NR frame according to an embodiment of the present disclosure is shown. Figure 6 Embodiments of can be combined with various embodiments of the present disclosure.

[0085] Referring to Figure 6 , a time slot includes multiple symbols in the time domain. For example, in the case of normal CP, one time slot can include 14 symbols. For example, in the case of extended CP, one time slot can include 12 symbols. Alternatively, in the case of normal CP, one time slot can include 7 symbols. However, in the case of extended CP, one time slot can include 6 symbols.

[0086] A carrier includes multiple subcarriers in the frequency domain. A resource block (RB) can be defined as multiple consecutive subcarriers in the frequency domain (e.g., 12 subcarriers). A bandwidth part (BWP) can be defined as multiple consecutive (physical) resource blocks ((P)RB) in the frequency domain, and the BWP can correspond to a parameter set (e.g., SCS, CP length, etc.). A carrier can include up to N BWPs (e.g., 5 BWPs). Data communication can be performed via an active BWP. Each element can be referred to as a resource element (RE) in a resource grid, and one complex symbol can be mapped to each element.

[0087] In addition, the radio interface between a UE and another UE or the radio interface between a UE and the network can include an L1 layer, an L2 layer, and an L3 layer. In various embodiments of the present disclosure, the L1 layer can mean the physical layer. Additionally, for example, the L2 layer can mean at least one of the MAC layer, the RLC layer, the PDCP layer, and the SDAP layer. Additionally, for example, the L3 layer can mean the RRC layer.

[0088] Hereinafter, the bandwidth part (BWP) and the carrier will be described in detail.

[0089] The BWP can be a continuous set of physical resource blocks (PRB) within a given parameter set. The PRB can be selected from a continuous subset of common resource blocks (CRB) for a given parameter set on a given carrier.

[0090] When using bandwidth adaptation (BA), it is not necessary for the receiving bandwidth and the transmitting bandwidth of a user equipment (UE) to be as wide (or large) as the bandwidth of the cell, and the receiving bandwidth and the transmitting bandwidth of the UE can be controlled (or adjusted). For example, the UE can receive information / configuration for bandwidth control (or adjustment) from the network / base station. In this case, bandwidth control (or adjustment) can be performed based on the received information / configuration. For example, bandwidth control (or adjustment) can include reduction / enlargement of the bandwidth, change of the position of the bandwidth, or change of the subcarrier spacing of the bandwidth.

[0091] For example, the bandwidth can be reduced during a duration with little activity to save power. For example, the position of the bandwidth can be repositioned (or moved) from the frequency domain. For example, the position of the bandwidth can be repositioned (or moved) from the frequency domain to enhance scheduling flexibility. For example, the subcarrier spacing of the bandwidth can be changed. For example, the subcarrier spacing of the bandwidth can be changed to authorize different services. A subset of the total cell bandwidth of a cell can be referred to as a bandwidth part (BWP). BA can be performed when the base station / network configures a BWP for the UE and when the base station / network notifies the UE of the currently active BWP among the BWPs.

[0092] For example, the BWP can be one of the active BWP, the initial BWP, and / or the default BWP. For example, the UE cannot monitor the downlink radio link quality in a DL BWP other than the active DL BWP within the primary cell (PCell). For example, the UE cannot receive a Physical Downlink Control Channel (PDCCH), a Physical Downlink Shared Channel (PDSCH), or a Channel State Information - Reference Signal (CSI-RS) (except for RRM) from outside the active DL BWP. For example, the UE cannot trigger a Channel State Information (CSI) report for an inactive DL BWP. For example, the UE cannot transmit a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH) from outside the non-active DL BWP. For example, in the case of the downlink, the initial BWP can be given as a set of consecutive resource blocks (RBs) for the remaining minimum system information (RMSI) control resource set (CORESET) (configured by the Physical Broadcast Channel (PBCH)). For example, in the case of the uplink, the initial BWP can be given by the System Information Block (SIB) for the random access procedure. For example, the default BWP can be configured by a higher layer. For example, the initial value of the default BWP can be the initial DL BWP. To save energy, if the UE cannot detect the Downlink Control Information (DCI) within a predetermined time period, the UE can switch the active BWP of the UE to the default BWP.

[0093] In addition, the BWP can be defined for SL. The same SL BWP can be used for transmission and reception. For example, the transmitting UE can transmit an SL channel or an SL signal within a specific BWP, and the receiving UE can receive the SL channel or the SL signal within the same specific BWP. In a licensed carrier, the SL BWP can be defined separately from the Uu BWP, and the SL BWP can have configuration signaling separate from the Uu BWP. For example, the UE can receive the configuration for the SL BWP from the base station / network. The SL BWP can be configured (in advance) for out-of-coverage NR V2X UEs and RRC_IDLE UEs. For a UE operating in the RRC_CONNECTED mode, at least one SL BWP can be activated within the carrier.

[0094] Figure 7 An example of the BWP based on an embodiment of the present disclosure is shown. Figure 7 The embodiments of can be combined with various embodiments of the present disclosure. Assume that in Figure 7 the embodiment of, the number of BWPs is 3.

[0095] Referring to Figure 7, a Common Resource Block (CRB) can be a carrier resource block numbered from one end of a carrier frequency band to the other end. Additionally, a PRB can be a resource block numbered within each BWP. Point A can indicate a common reference point of the resource block grid.

[0096] It can be configured by Point A, the offset relative to Point A (N start BWP ) and the bandwidth (N size BWP ). For example, Point A can be an external reference point of the PRB of a carrier, and the subcarrier 0 of all parameter sets (e.g., all parameter sets supported by the network on the corresponding carrier) is aligned at Point A. For example, the offset can be the PRB distance between the lowest subcarrier within a given parameter set and Point A. For example, the bandwidth can be the number of PRBs within a given parameter set.

[0097] Hereinafter, V2X or SL communication will be described.

Figure 8 The embodiments of can be combined with various embodiments of the present disclosure. More specifically, Figure 8 (a) in shows the user plane protocol stack, and Figure 8 (b) in shows the control plane protocol stack.

[0099] Next, the Sidelink Synchronization Signal (SLSS) and synchronization information will be described in detail.

[0100] The SLSS can include a Primary Sidelink Synchronization Signal (PSSS) and a Secondary Sidelink Synchronization Signal (SSSS) as SL-specific sequences. The PSSS can be referred to as the Sidelink Primary Synchronization Signal (S-PSS), and the SSSS can be referred to as the Sidelink Secondary Synchronization Signal (S-SSS). For example, an M sequence of length 127 can be used for the S-PSS, and a gold sequence of length 127 can be used for the S-SSS. For example, the UE can use the S-PSS for initial signal detection and synchronization acquisition. For example, the UE can use the S-PSS and S-SSS for obtaining detailed synchronization and for detecting the synchronization signal ID.

[0101] The Physical Sidelink Broadcast Channel (PSBCH) can be a (broadcast) channel for transmitting default (system) information that the UE must first know before SL signal transmission / reception. For example, the default information can be information related to SLSS, duplex mode (DM), time division duplex (TDD) uplink / downlink (UL / DL) configuration, information related to resource pools, the type of application related to SLSS, subframe offset, broadcast information, etc. For example, in order to evaluate the PSBCH performance, in NR V2X, the payload size of the PSBCH can be 56 bits, including a 24-bit CRC.

[0102] The S-PSS, S-SSS, and PSBCH can be included in a block format that supports periodic transmission (e.g., SL Synchronization Signal (SS) / PSBCH block, hereinafter, Sidelink Synchronization Signal Block (S-SSB)). The S-SSB can have the same parameter set (i.e., SCS and CP length) as the Physical Sidelink Control Channel (PSCCH) / Physical Sidelink Shared Channel (PSSCH) in the carrier, and the transmission bandwidth can be within a (pre-)configured Sidelink (SL) BWP. For example, the S-SSB can have a bandwidth of 11 resource blocks (SB). For example, the PSBCH can span 11 RBs. Additionally, the frequency position of the S-SSB can be (pre-)configured. Therefore, the UE does not have to perform hypothesis detection at the frequency to discover the S-SSB in the carrier.

[0103] Figure 9 A UE that performs V2X or SL communication according to an embodiment of the present disclosure is shown. Figure 9 Embodiments can be combined with various embodiments of the present disclosure.

[0104] Referring to Figure 9 , in V2X or SL communication, the term "UE" can generally refer to the user's UE. However, if a network device such as a BS transmits / receives signals according to the communication scheme between UEs, the BS can also be regarded as a type of UE. For example, UE 1 can be the first wireless device 100, and UE 2 can be the second wireless device 200.

[0105] For example, UE 1 can select a resource unit corresponding to a specific resource in a resource pool that means a set of resource series. Additionally, UE 1 can transmit an SL signal by using the resource unit. For example, the resource pool in which UE 1 can transmit signals can be configured to UE 2 as the receiving UE, and the signal of UE 1 can be detected in the resource pool.

[0106] In this document, if UE 1 is within the connection range of the BS, the BS can inform UE 1 of the resource pool. Otherwise, if UE 1 is outside the connection range of the BS, another UE can inform UE 1 of the resource pool, or UE 1 can use a pre-configured resource pool.

[0107] Generally, a resource pool can be configured with multiple resources as units, and each UE can select one or more resource units to use in its SL signal transmission.

[0108] In the following text, resource allocation in SL will be described.

[0109] Figure 10 The process of a UE performing V2X or SL communication based on a transmission mode according to an embodiment of the present disclosure is shown. Figure 10 The embodiments can be combined with various embodiments of the present disclosure. In various embodiments of the present disclosure, the transmission mode can be referred to as a mode or a resource allocation mode. In the following text, for ease of description, in LTE, the transmission mode can be referred to as the LTE transmission mode. In NR, the transmission mode can be referred to as the NR resource allocation mode.

[0110] For example, Figure 10 (a) in shows UE operations related to LTE transmission mode 1 or LTE transmission mode 3. Alternatively, for example, Figure 10 (a) in shows UE operations related to NR resource allocation mode 1. For example, LTE transmission mode 1 can be applied to regular SL communication, and LTE transmission mode 3 can be applied to V2X communication.

[0111] For example, Figure 10 (b) in shows UE operations related to LTE transmission mode 2 or LTE transmission mode 4. Alternatively, for example, Figure 10 (b) in shows UE operations related to NR resource allocation mode 2.

[0112] Referring to Figure 10 (a) in, in LTE transmission mode 1, LTE transmission mode 3, or NR resource allocation mode 1, the BS can schedule SL resources for the UE to use in SL transmission. For example, the BS can perform resource scheduling on UE 1 through PDCCH (more specifically, downlink control information (DCI)), and UE 1 can perform V2X or SL communication for UE 2 according to the resource scheduling. For example, UE 1 can send sidelink control information (SCI) to UE 2 through the physical sidelink control channel (PSCCH), and then send data based on the SCI to UE 2 through the physical sidelink shared channel (PSSCH).

[0113] Referring to Figure 10In (b), in LTE transmission mode 2, LTE transmission mode 4, or NR resource allocation mode 2, the UE can determine the SL transmission resources within the SL resources configured by the BS / network or pre-configured SL resources. For example, the configured SL resources or pre-configured SL resources can be resource pools. For example, the UE can autonomously select or schedule the resources for SL transmission. For example, the UE can perform SL communication by autonomously selecting the resources in the configured resource pool. For example, the UE can autonomously select the resources within the selection window by performing a sensing and resource (re)selection process. For example, sensing can be performed in units of sub-channels. In addition, the UE 1 that has autonomously selected resources in the resource pool can send the SCI to the UE 2 via the PSCCH, and then can send the data based on the SCI to the UE 2 via the PSSCH.

[0114] Figure 11 Shows three playback types based on embodiments of the present disclosure. Figure 11 Embodiments can be combined with various embodiments of the present disclosure. Specifically, Figure 11 In (a) shows broadcast-type SL communication, Figure 11 In (b) shows unicast-type SL communication, and Figure 11 In (c) shows multicast-type SL communication. In the case of unicast-type SL communication, the UE can perform one-to-one communication for another UE. In the case of multicast-type SL transmission, the UE can perform SL communication for one or more UEs in the group to which the UE belongs. In various embodiments of the present disclosure, SL multicast communication can be replaced by SL multi-cast communication, SL one-to-many communication, etc.

[0115] In addition, in the next-generation system, various usage scenarios can be supported. For example, services for communication in autonomous vehicles, smart cars, or connected cars, etc. can be considered. For such services, each vehicle can receive and send (or transmit) information as a user equipment capable of performing communication. And, depending on the situation, each vehicle can select the resources for communication with the help (or assistance) of a base station or without any help (or assistance) from a base station, and send messages to other UEs and receive messages from other UEs.

[0116] On the other hand, as one of the problems in NR sidelink (SL), there is a problem related to the prioritization between uplink (UL) transmission and SL transmission on the Uu interface. The prioritization scheme can be applied between SL transmission and UL transmission within a RAT or between SL transmission and UL transmission between RATs. For example, the prioritization between RATs can be applied between LTE UL transmission and NR SL transmission or between LTE SL transmission and NR UL transmission.

[0117] For example, in LTE V2X, the following three cases are discussed as cases where a priority sorting scheme should be applied. That is, from the perspective of a UE, when UL transmission and SL transmission are simultaneously performed on the same carrier or a shared carrier, or when UL transmission and SL transmission are simultaneously performed on different carriers, according to the first case (Case 1) to the third case (Case 3) of Table 5 below, there is a situation where UL transmission and SL transmission cannot be simultaneously performed when they overlap on the time axis. For example, in the case of the first case, if these two transmissions overlap on the time axis, although UL transmission and SL transmission each have different TX chains and power budgets, the UE may not be able to perform UL transmission or SL transmission. Similarly, in the case of the second case, even if UL transmission and SL transmission have different TX chains and share power, if these two transmissions overlap on the time axis, the UE may also not be able to perform UL transmission or SL transmission. In Case 3, when UL transmission and SL transmission share both the TX chain and power, there may be issues related to determining which of these two transmissions is discarded or how to perform power allocation for these two transmissions when they overlap on the time axis.

[0118] Table 5 shows an example of simultaneous execution of UL transmission and SL transmission.

[0119] [Table 5]

[0120]

[0121]

[0122] Regarding the problems caused in LTE V2X, the LTE V2X MAC procedure is specified as shown in Table 6 below in terms of the procedure. Details included in Table 6 can be referred to in 3GPP TS 36.213.

[0123] [Table 6]

[0124]

[0125] Briefly describe the operations in Table 6. When the above three conditions are met, V2X SL transmission takes precedence over UL transmission. The above three conditions may include the condition that the MAC layer cannot transmit all UL transmissions and all SL transmissions simultaneously, the condition that UL transmission is not prioritized by a higher layer specification, and the condition that the value associated with the highest priority of the SL logical channel (LCH) is less than a preconfigured SL threshold. For example, the SL threshold may include thresSL-TxPrioritization. For example, when comparing two values related to priorities, the smaller value of one party may mean that the actual priority of the item associated with the smaller value is relatively higher than the priority of the item associated with the other value. For example, the situation where all UL transmissions and all SL transmissions cannot be transmitted simultaneously at the same time may include the first to third cases in Table 5 above. Alternatively, the situation where all UL transmissions and all SL transmissions cannot be transmitted simultaneously at the same time may be included in the scenario related to Table 6. For example, referring to the 3GPP document TS 36.321, thresSL-TxPrioritization may represent the threshold used to determine whether V2X SL transmission takes precedence over UL transmission when V2X SL transmission overlaps with UL transmission on the time axis. Additionally, referring to the 3GPP document TS36.331, thresSL-TxPrioritization can be used to override the thresSL-TxPrioritization configured in the V2X SL preconfiguration.

[0126] On the other hand, even in NR V2X, the priorities of UL transmission and SL transmission must be adjusted according to the conflicts that occur as described above. For example, the conflict may include the situation where these two transmissions overlap on the time axis. In the present disclosure, a method for prioritizing based on the conflict between UL transmission and SL transmission within or between RATs related to the NR sidelink is proposed. First, the scenarios to which the proposed prioritization method can be applied will be illustrated by examples.

[0127] 1. Inter-RAT UL / SL Conflict Scenarios

[0128] A. Conflict between LTE UL transmission and NR SL transmission: For example, from the perspective of the UE's transmission, the situation where the LTE UL transmission of MCG or SCG overlaps with the NR SL transmission on the UE's transmission time axis.

[0129] B. Conflict between NR UL transmission and LTE SL transmission: For example, from the perspective of the UE's transmission, the situation where the NR UL transmission of MCG or SCG overlaps with the LTE SL transmission on the UE's transmission time axis.

[0130] 2. Intra-RAT UL / SL Conflict Scenarios

[0131] Conflict between NR UL transmission and NR SL transmission: For example, from the perspective of the UE's transmission, the situation where the NR UL transmission and the NR SL transmission of the MCG or SCG overlap on the UE's transmission time axis.

[0132] In the following, in the above scenario, it is proposed that the UE makes the SL transmission take precedence over the UL transmission or discards the SL transmission based on a pre-configured threshold. Here, the UL transmission can be performed based on the PUCCH resource or the PUSCH resource pre-configured for the UE. For example, the UL transmission can include PUCCH or PUSCH transmitted through the PUCCH resource or the PUSCH resource pre-configured for the UE.

[0133] According to an embodiment of the present disclosure, in NR, since the information related to the priority is not always linked to the PUCCH resource, when the UL transmission is a PUCCH transmission, similar to the principle of LTE in UL / SL prioritization, when the value related to the highest priority of the SL LCH related to the SL transmission is less than the pre-configured SL threshold, the scheme of making the SL transmission take precedence over the UL transmission can be applied. For example, the SL threshold can include thresSL-TxPrioritization. For example, the situation where the value related to the highest priority of the SL LCH related to the SL transmission is less than the pre-configured SL threshold can include the situation where the priority of the SL LCH related to the SL transmission is higher than the priority related to the threshold or the priority of the SL LCH is higher than the priority corresponding to the pre-configured SL threshold. Here, it is proposed that the SL threshold for comparing the priority of the SL transmission can be different according to what the UL transmission with the conflict includes.

[0134] For example, PUCCH can be used to transmit information related to at least one of a scheduling request (SR), HARQ ACK / NACK related to PDSCH transmission, and / or channel state information (CSI). Generally, HARQ ACK / NACK and SR can have relatively higher priorities than CSI because HARQ ACK / NACK and SR are information related to the success or failure of the initial transmission or are resource scheduling requests for urgently needed data, while CSI is used for the purpose of adapting to the link state by reporting the channel state. Therefore, the base station can pre-configure the SL threshold differently according to the content to be transmitted through the PUCCH. For example, the SL threshold can include the thresSL-TxPrioritization value.

[0135] For example, a first SL threshold (e.g., thresSL-TxPrioritization1) applied to the priority between PUCCH and SL transmissions related to HARQ ACK / NACK and / or SR can be configured to be relatively smaller than a second SL threshold (e.g., thresSL-Txprioritization2) applied to the priority between PUCCH and SL transmissions related to CSI transmission.

[0136] For example, when a PSFCH transmission conflicts with a UL transmission, in terms of the priority between the PSFCH transmission and the UL transmission, the priority of the PSFCH transmission can be the same as the highest priority among the PSCCH / PSSCH related to the PSFCH. For example, when the UL transmission is not related to the SL HARQ report, if the UL transmission is configured as a high priority from a higher layer, or if the UL transmission is a UL transmission related to DCI indicating "high" in the priority field and an SL threshold related to URLLC is configured, the UE can perform the UL transmission or the PSFCH transmission based on the SL threshold and the priority of the SL transmission. Here, if the SL threshold related to URLLC is not configured, the UE can prioritize the UL transmission over the PSFCH transmission. For example, if the priority value related to the SL transmission is less than the SL threshold, the UE can prioritize the SL transmission over the UL transmission, and if the priority value is greater than the SL threshold, the UE can prioritize the UL transmission over the SL transmission. For example, when the UL transmission is not related to the SL HARQ report, if the UL transmission is configured as a high priority from a higher layer or the UL transmission is not a UL transmission related to DCI indicating "high" in the priority field, the UE can perform prioritization based on the SL threshold not related to URLLC. Additionally, for example, the UE can always prioritize the PRACH and PUSCH scheduled by RAR UL grant.

[0137] Figure 12 A process for determining whether to perform an SL transmission according to an embodiment of the present disclosure is shown. Figure 12 Embodiments of can be combined with various embodiments of the present disclosure.

[0138] Referring to Figure 12, the SL priority value can be 3. For example, the SL priority value can represent a value related to the priority included in the LCH associated with SL transmission. For example, the first SL threshold (e.g., thresSL-TxPrioritization1) and the second SL threshold (e.g., thresSL-TxPrioritization2) can be 2 and 4 respectively. Here, the UE can perform prioritization related to SL transmission and UL transmission based on two differently configured SL thresholds. For example, if a conflict occurs between SL transmission related to HARQ ACK / NACK and / or SR and PUCCH transmission, the UE can compare the first SL threshold with the SL priority value and prioritize UL PUCCH transmission because the SL transmission has a lower priority. At this time, for example, the UE can discard the SL transmission. Conversely, if a conflict occurs, for example, between low-priority SL transmission related to CSI and PUCCH, since the SL priority value is less than the second SL threshold, the UE can discard the UL PUCCH transmission.

[0139] In the above, it is assumed that the priority of the PUCCH related to HARQ ACK / NACK and SR is higher than the priority of the PUCCH related to CSI, and the priority relationship between these PUCCHs can be predefined and reflected in the SL threshold signaled by the base station. For example, the SL threshold can include thresSL-TxPrioritization. For example, the base station can configure the SL threshold related to URLLC transmission to be smaller in order to perform emergency URLLC transmission and protect the associated HARQ ACK / NACK. For example, this threshold configuration can be signaled periodically and changed.

[0140] According to an embodiment of the present disclosure, when there is an LCH priority value related to the PUCCH, the UE can determine whether to discard the SL transmission by comparing the priority between UL transmission and SL transmission. For example, in the case of SR in NR, the priority of SR can be the priority of the LCH related to SR. For example, in the case of SR, by directly comparing the priority of the LCH related to the PUCCH with the priority of the SL LCH, the transmission related to the LCH with a higher priority can be prioritized. That is, for example, the transmission related to the LCH with a lower priority as a comparison result can be discarded.

[0141] According to an embodiment of the present disclosure, the UE can determine which transmission will be prioritized in the UL / SL conflict scenario, thereby preventing the phenomenon that all data transmissions fail in the conflict scenario.

[0142] Figure 13Illustrates a process by which a UE determines whether to transmit an SL signal according to an embodiment of the present disclosure. Figure 13 Embodiments may be combined with various embodiments of the present disclosure.

[0143] Referring to Figure 13 , for example, the UE may include at least one of a VRU, V2X, and / or RSU. Figure 13 Is a flowchart for explaining a method by which a UE determines whether to discard the transmission of a UL signal and preferentially transmit an SL signal in the case where the SL signal to be transmitted from the UE overlaps with the UL signal to be transmitted from the UE in the time domain.

[0144] Referring to Figure 13 , when the transmission of the UL signal and the transmission of the SL signal overlap with each other in the time domain, in step S1310, the UE may compare a preconfigured threshold with the priority associated with the SL signal. Here, the priority associated with the SL signal may be the LCH priority configured for the SL signal or the highest priority among the LCH priorities configured for the SL signal. Additionally, here, the preconfigured threshold may be configured differently based on the content associated with the UL signal. For example, the threshold configured when the UL signal is a signal related to HARQ ACK / NACK and SR may be configured to be a smaller value than the threshold configured when the UL signal is a signal related to CSI.

[0145] In step S1320, the UE may determine whether to transmit the SL signal prior to the UL signal based on the comparison result between the preconfigured threshold corresponding to the content associated with the UL signal and the priority associated with the SL signal. Specifically, when the priority value associated with the SL signal has a value smaller than the preconfigured threshold (i.e., when the priority of the SL signal is prior to the priority corresponding to the preconfigured threshold), the UE may discard the UL signal and preferentially transmit the SL signal. On the other hand, when the priority value associated with the SL signal has a value larger than the preconfigured threshold (i.e., when the priority corresponding to the preconfigured threshold has a priority prior to the priority of the SL signal), the UE may discard the SL signal and transmit the UL signal.

[0146] Figure 14 Illustrates a process by which a first device performs any UL transmission according to an embodiment of the present disclosure. Figure 14 Embodiments may be combined with various embodiments of the present disclosure.

[0147] Referring to Figure 14, in step S1410, the first device may determine the priority associated with the sidelink (SL) transmission. In step S1420, the first device may receive information related to the SL threshold associated with the uplink (UL) transmission from the base station. In step S1430, the first device may perform either the SL transmission or the UL transmission based on the priority associated with the SL transmission and the SL threshold. For example, the SL transmission and the UL transmission may overlap in the time domain, and the SL threshold may be configured for the first device based on the priority associated with the UL transmission.

[0148] For example, the priority associated with the SL transmission may be determined based on the first logical channel (LCH) associated with the SL transmission.

[0149] For example, the unexecuted transmission among the SL transmission or the UL transmission may be discarded.

[0150] For example, based on the priority associated with the SL transmission having a value greater than the SL threshold, the UL transmission may be performed among the SL transmission or the UL transmission.

[0151] For example, the priority associated with the UL transmission may include the priority associated with the packet transmitted through the UL transmission.

[0152] For example, the packet transmitted through the UL transmission may include information related to at least one of the physical uplink control channel (PUCCH), scheduling request (SR), hybrid automatic repeat request (HARQ) feedback, and / or channel state information (CSI).

[0153] For example, the priority associated with the packet transmitted through the UL transmission may be configured by the base station.

[0154] For example, the priority associated with the packet transmitted through the UL transmission may be "high".

[0155] For example, the priority associated with the packet transmitted through the UL transmission may change periodically.

[0156] For example, the priority associated with the UL transmission may be received from the base station.

[0157] For example, the priority associated with the UL transmission may be received from the base station through the downlink control information (DCI).

[0158] For example, the priority associated with the UL transmission may be received from the base station through the radio resource control (RRC) message.

[0159] For example, the priority related to SL transmission can be included in the first LCH related to SL transmission, the priority related to UL transmission can be included in the second LCH related to UL transmission, and the performed transmission can be executed as one of SL transmission and UL transmission based on the priority related to SL transmission and the priority related to UL transmission.

[0160] The above-described embodiments can be applied to various apparatuses described below. For example, the processor 102 of the first device 100 can determine the priority related to sidelink SL transmission. Also, the processor 102 of the first device 100 can control the transceiver 106 to receive information related to the SL threshold related to uplink UL transmission from the base station 300. Also, the processor 102 of the first device 100 can control the transceiver 106 to execute one of SL transmission and UL transmission based on the priority related to SL transmission and the SL threshold. For example, SL transmission and UL transmission can overlap in the time domain, and the SL threshold can be configured for the first device based on the priority related to UL transmission.

[0161] According to an embodiment of the present disclosure, a first device for performing wireless communication can be supported. For example, the first device can include: one or more memories that store instructions; one or more transceivers; and one or more processors connected to the one or more memories and the one or more transceivers. For example, the one or more processors can execute the instructions to: determine the priority related to sidelink SL transmission; receive information related to the SL threshold related to uplink UL transmission from a base station; and based on the priority related to the SL transmission and the SL threshold, execute one of the SL transmission and the UL transmission, wherein the SL transmission overlaps with the UL transmission in the time domain, and wherein the SL threshold is configured for the first device based on the priority related to the UL transmission.

[0162] According to an embodiment of the present disclosure, a device configured to control a first device can be proposed. For example, the device can include: one or more processors; and one or more memories operably connected to the one or more processors and storing instructions. For example, the one or more processors can execute the instructions to: determine the priority related to sidelink SL transmission; receive information related to the SL threshold related to uplink UL transmission from a base station; and based on the priority related to the SL transmission and the SL threshold, execute one of the SL transmission and UL transmission, wherein the SL transmission overlaps with the UL transmission in the time domain, and wherein the SL threshold is configured for the first device based on the priority related to the UL transmission.

[0163] According to an embodiment of the present disclosure, a non-transitory computer-readable storage medium storing instructions may be supported. For example, when the instructions are executed, they may cause a first device to: determine a priority associated with sidelink (SL) transmission; receive information related to an SL threshold associated with uplink (UL) transmission from a base station; and perform one of the SL transmission or the UL transmission based on the priority associated with the SL transmission and the SL threshold, wherein the SL transmission overlaps with the UL transmission in the time domain, and wherein the SL threshold is configured for the first device based on a priority associated with the UL transmission.

[0164] Figure 15 A process of a base station receiving a UL transmission according to an embodiment of the present disclosure is shown. Figure 15 Embodiments of may be combined with various embodiments of the present disclosure.

[0165] Refer to Figure 15 , in step S1510, the base station may send information related to an SL threshold associated with the UL transmission to the first device based on a priority associated with the UL transmission. In step S1520, the base station may receive a UL transmission from the first device. For example, the UL transmission may be performed by the first device based on a priority associated with the SL transmission and the SL threshold.

[0166] For example, the priority associated with the UL transmission may include a priority associated with a packet transmitted via the UL transmission.

[0167] The above embodiments may be applied to various apparatuses described below. For example, the processor 202 of the base station 200 may control the transceiver 206 to send information related to an SL threshold associated with the UL transmission to the first device 100 based on a priority associated with the UL transmission. And, the processor 202 of the base station 200 may control the transceiver 206 to receive a UL transmission from the first device 100. For example, the UL transmission may be performed by the first device based on a priority associated with the SL transmission and the SL threshold.

[0168] According to an embodiment of the present disclosure, a base station for performing wireless communication can be supported. For example, the base station can include: one or more memories that store instructions; one or more transceivers; and one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors send information related to a sidelink (SL) threshold related to uplink (UL) transmission to a first device based on a priority related to UL transmission; and receive a UL transmission from the first device, wherein the first device performs the UL transmission based on a priority related to SL transmission and the SL threshold.

[0169] For example, the priority related to UL transmission can include a priority related to a packet transmitted by UL transmission.

[0170] Hereinafter, devices to which respective embodiments of the present disclosure can be applied will be described.

[0171] Various descriptions, functions, processes, proposals, methods, and / or operation flows of the present disclosure described in this document can be applied to, but are not limited to, various fields that require wireless communication / connection (e.g., 5G) between devices.

[0172] Hereinafter, a more detailed description will be given with reference to the drawings. In the following drawings / descriptions, unless otherwise described, the same reference numerals can represent the same or corresponding hardware blocks, software blocks, or functional blocks.

[0173] Figure 16 A communication system (1) based on an embodiment of the present disclosure is shown.

[0174] Refer to Figure 16, A communication system (1) applying various embodiments of the present disclosure includes a wireless device, a base station (BS), and a network. Herein, a wireless device refers to a device that performs communication using a radio access technology (RAT) (e.g., 5G new RAT (NR) or Long-Term Evolution (LTE)), and can be referred to as a communication / radio / 5G device. The wireless device may include, without limitation, a robot (100a), a vehicle (100b-1 and 100b-2), an extended reality (XR) device (100c), a handheld device (100d), a household appliance (100e), an Internet of Things (IoT) device (100f), and an artificial intelligence (AI) device / server (400). For example, a vehicle may include a vehicle with wireless communication capabilities, an autonomous vehicle, and a vehicle capable of performing vehicle-to-vehicle communication. Herein, a vehicle may include an unmanned aerial vehicle (UAV) (e.g., a drone). The XR device may include an augmented reality (AR) / virtual reality (VR) / mixed reality (MR) device and may be implemented in the form of a head-mounted device (HMD), a head-up display (HUD) mounted in a vehicle, a television, a smartphone, a computer, a wearable device, a household appliance device, a digital sign, a vehicle, a robot, etc. The handheld device may include a smartphone, a smart board, a wearable device (e.g., a smart watch or smart glasses), and a computer (e.g., a notebook). The household appliance may include a TV, a refrigerator, and a washing machine. The IoT device may include sensors and smart meters. For example, the BS and the network may be implemented as wireless devices, and a specific wireless device (200a) may operate as a BS / network node with respect to other wireless devices.

[0175] The wireless devices 100a to 100f may be connected to the network 300 via the BS 200. AI technology may be applied to the wireless devices 100a to 100f, and the wireless devices 100a to 100f may be connected to the AI server 400 via the network 300. The network 300 may be configured using a 3G network, a 4G (e.g., LTE) network, or a 5G (e.g., NR) network. Although the wireless devices 100a to 100f may communicate with each other via the BS 200 / network 300, the wireless devices 100a to 100f may perform direct communication (e.g., sidelink communication) with each other without passing through the BS / network. For example, the vehicles 100b-1 and 100b-2 may perform direct communication (e.g., vehicle-to-vehicle (V2V) / vehicle-to-everything (V2X) communication).

[0185] Figure 18 A signal processing circuit for transmitting signals according to an embodiment of the present disclosure is shown.

[0186] Referring to Figure 18 , the signal processing circuit (1000) may include a scrambler (1010), a modulator (1020), a layer mapper (1030), a precoder (1040), a resource mapper (1050), and a signal generator (1060). The operations / functions of Figure 18 may be performed, not limited to Figure 17 the processors (102, 202) and / or transceivers (106, 206) of Figure 17implemented by a processor (102, 202) and / or a transceiver (106, 206). Figure 18 hardware components. For example, blocks 1010 to 1060 can be implemented by Figure 17 a processor (102, 202). Alternatively, blocks 1010 to 1050 can be implemented by Figure 17 a processor (102, 202), and block 1060 can be implemented by Figure 17 a transceiver (106, 206).

[0187] The codeword can be converted into a radio signal via Figure 18 the signal processing circuit (1000). Here, the codeword is a sequence of coded bits of an information block. The information block can include transport blocks (e.g., UL-SCH transport blocks, DL-SCH transport blocks). The radio signal can be transmitted through various physical channels (e.g., PUSCH and PDSCH).

[0188] Specifically, the codeword can be converted by a scrambler 1010 into a scrambled bit sequence. The scrambling sequence for scrambling can be generated based on an initial value, and the initial value can include the ID information of the wireless device. The scrambled bit sequence can be modulated by a modulator 1020 into a sequence of modulation symbols. The modulation scheme can include pi / 2-binary phase shift keying (pi / 2-BPSK), m-phase shift keying (m-PSK), and m-quadrature amplitude modulation (m-QAM). The complex sequence of modulation symbols can be mapped by a layer mapper 1030 to one or more transmission layers. The modulation symbols of each transmission layer can be mapped (precoded) by a precoder 1040 to the corresponding antenna port(s). The output z of the precoder 1040 can be obtained by multiplying the output y of the layer mapper 1030 by an N*M precoding matrix W. Here, N is the number of antenna ports, and M is the number of transmission layers. The precoder 1040 can perform precoding after performing transform precoding (e.g., DFT) on the complex modulation symbols. Alternatively, the precoder 1040 can perform precoding without performing transform precoding.

[0189] A resource mapper 1050 can map the modulation symbols of each antenna port to time-frequency resources. The time-frequency resources can include multiple symbols in the time domain (e.g., CP-OFDMA symbols and DFT-s-OFDMA symbols) and multiple subcarriers in the frequency domain. A signal generator 1060 can generate a radio signal from the mapped modulation symbols, and the generated radio signal can be transmitted to other devices through each antenna. For this purpose, the signal generator 1060 can include an inverse fast Fourier transform (IFFT) module, a cyclic prefix (CP) inserter, a digital-to-analog converter (DAC), and an upconverter.

[0190] It can be configured in a manner opposite to the signal processing procedure (1010 to 1060) of Figure 18 the signal processing procedure for the signals received in a wireless device. For example, a wireless device (e.g., Figure 17 100 and 200) can receive radio signals from the outside through an antenna port / transceiver. The received radio signals can be converted into baseband signals by a signal restorer. For this purpose, the signal restorer can include a frequency down-converter, an analog-to-digital converter (ADC), a CP remover, and a fast Fourier transform (FFT) module. Next, the baseband signals can be restored into codewords through a resource demapping procedure, a post-coding procedure, a demodulation processor, and a descrambling procedure. The codewords can be restored into the original information blocks through decoding. Therefore, the signal processing circuit (not illustrated) for receiving signals can include a signal restorer, a resource demapper, a post-encoder, a demodulator, a descrambler, and a decoder.
