Description

【Technical Field】 【0001】 The present invention relates to wireless communication, and more particularly, to an apparatus, system, and method for side-link physical channel expansion for unlicensed spectrum in, for example, 5G NR systems and later. 【Background Art】 【0002】 The use of wireless communication systems has been increasing rapidly. In recent years, wireless devices such as smartphones and tablet computers have become increasingly high-performance. In addition to supporting telephone functions, many mobile devices now provide access to the Internet, email, text messaging, and navigation using the global positioning system (GPS), and can operate sophisticated applications that utilize those functionalities. 【0003】 Some examples of wireless communication standards include GSM, UMTS (associated with, for example, the WCDMA or TD-SCDMA air interface), LTE, LTE Advanced (LTE-A), NR, HSPA, 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), IEEE802.11 (WLAN or Wi-Fi), BLUETOOTH (trademark), and the like. 【0004】 The ever-increasing features and functionalities introduced into wireless communication devices also create a continuous need to improve both wireless communication and wireless communication devices. In particular, it is crucial to ensure the accuracy of transmitted and received signals via user equipment (UE) devices, such as cellular phones, base stations, and relay stations used in wireless cellular communications. In addition, increasing the functionality of UE devices can place a significant burden on their battery life. Therefore, it is also very important to reduce the power requirements of UE device designs while ensuring that UE devices maintain good transmit and receive capabilities to improve communication. Thus, improvements in this area are desirable. [Overview of the project] 【0005】 The embodiments relate to wireless communication, and more particularly to apparatus, systems, and methods for side-link physical channel expansion for unlicensed spectrum in, for example, 5G NR systems and beyond. 【0006】 For example, in some embodiments, the UE (e.g., the UE's baseband processor) may be configured to determine whether a subchannel can be used for sidelink physical channel transmission based on a condition associated with the number of physical resource blocks (PRBs) configured for the sidelink physical channel, for consecutive resource block (RB) based sidelink physical channel transmission in the SL-U. In some cases, the sidelink physical channel may be a PSCCH or a PSSCH. Furthermore, the UE may be configured to transmit the sidelink physical channel depending on whether it has determined that a condition is met. The condition may be that the total number of PRBs in the subchannel that do not overlap with the protection bandwidth is greater than or equal to the number of PRBs configured for the sidelink physical channel, or that the leading portion of the PRBs in the subchannel that do not overlap with the protection bandwidth is greater than or equal to the number of PRBs configured for the sidelink physical channel. 【0007】 As another example, in some embodiments, the UE (e.g., the UE's baseband processor) may be configured to configure the transmit bandwidth to satisfy the occupied channel bandwidth (OCB) requirement. The UE may be configured to transmit S-SSB for a number of repetitions configured in the frequency domain. Gaps may be included between repetitions to satisfy the OCB requirement. 【0008】 As an additional example, in some embodiments, the UE (e.g., the UE's baseband processor) may be configured to create a gap between the common PRB and the dedicated PRB to avoid in-band radiation (IBE) from the common PRB to the dedicated PRB. The UE may be configured to transmit PSFCH using the gap between the common PRB and the dedicated PRB. 【0009】 As a further example, in some embodiments, the UE (e.g., the UE's baseband processor) may be configured to use either a frequency-first interlacing rule or an interlace-first interlacing rule for each orthogonal frequency division multiplexing (OFDM) symbol (e.g., the OFDM symbol for the subchannel) for multiple interlaces per subchannel. In addition, the UE may be configured to use either a subchannel-first interlacing rule, a frequency-first interlacing rule, or an interlace-first interlacing rule for each OFDM symbol (e.g., the OFDM symbol for the subchannel) for interlacing multiple subchannels in transmission. 【0010】 The techniques described herein may be implemented in and / or used in several different types of devices, including but not limited to unmanned aerial vehicles (UAVs), unmanned aerial vehicle controllers (UACs), UTM servers, base stations, access points, cellular phones, tablet computers, wearable computing devices, portable media players, and various other computing devices. 【0011】 This summary of the invention is intended to provide a brief overview of some of the subject matter described herein. Therefore, it should be understood that the features described above are merely examples and should not be construed as narrowing the scope or spirit of the subject matter described herein.

[Modes for carrying out the invention] 【0027】 acronym This disclosure uses a variety of acronyms throughout. The definitions of the most frequently used acronyms that may appear throughout this disclosure are as follows: ● 3GPP: Third Generation Partnership Project ● UE: User Equipment ● RF: Radio frequency ● BS: Base station ● DL: Downlink ● UL: Uphill Link ● LTE: Long-Term Evolution ● NR: New radio ● 5GS: 5G system ● 5GMM: 5GS Mobility Management ● 5GC / 5GCN: 5G Core Network ● SIM: Subscriber Identification Module ● eSIM: Embedded subscriber identification module ● IE: Information element ● CE: Control element ● MAC: Media Access Control ● SSB: Synchronization Signal Block ● PDCCH: Physical Downlink Control Channel ● PDSCH: Physical Downlink Shared Channel ● RRC: Wireless Resource Control term 【0028】 The following is an explanation of the terms used in this disclosure. 【0029】 Memory medium – any of the various types of non-temporary memory devices or storage devices. The term “memory medium” is intended to include, for example, installation media such as CD-ROMs, floppy disks, or tape devices; computer system memory or random access memory such as DRAM, DDR RAM, SRAM, EDO RAM, Rambus RAM; non-volatile memory such as flash, hard drives, or optical storage; registers, or other similar types of memory elements. The memory medium may also include other types of non-temporary memory, or combinations thereof. In addition, the memory medium may be located on a first computer system on which a program is executed, or on a second different computer system connected to the first computer system via a network such as the Internet. In the latter case, the second computer system can provide program instructions to the first computer for execution. The term “memory medium” may include two or more memory mediums that may exist in different locations, for example, on different computer systems connected via a network. The memory medium may store program instructions (embodied, for example, as computer programs) that can be executed by one or more processors. 【0030】 Carrier medium - memory media as described above, as well as physical transmission media such as buses and networks, and / or other physical transmission media that transmit signals such as electrical signals, electromagnetic signals, or digital signals. 【0031】 Programmable hardware elements include various hardware devices comprising multiple programmable function blocks connected via programmable interconnectors. Examples include field programmable gate arrays (FPGAs), programmable logic devices (PLDs), field programmable object arrays (FPOAs), and complex PLDs (CPLDs). Programmable function blocks can range in granularity from fine-grained (combinatorial logic or lookup tables) to coarse-grained (arithmetic logic units or processor cores). Programmable hardware elements may also be referred to as "reconfigurable logic." 【0032】 User equipment (UE) (or “UE device”) – various types of mobile or portable computer system devices that perform wireless communication. Examples of UE devices include mobile phones or smartphones (e.g., iPhone®, Android®-based phones), portable gaming devices (e.g., Nintendo DS®, PlayStation Portable®, Gameboy Advance®, iPhone®), laptops, wearable devices (e.g., smartwatches, smart glasses), PDAs, mobile internet devices, music players, data storage devices, other handheld devices, unmanned aerial vehicles (UAVs) (e.g., drones), and UAV controllers (UACs). Generally, the terms “UE” or “UE device” can be broadly defined to encompass any electronic device, computing device, and / or telecommunications device (or combination of devices) that is easily carried by a user and capable of wireless communication. 【0033】 Base station - The term "base station" has the full scope of its ordinary meaning and includes at least a radio communication station that is installed in a fixed location and used for communication as part of a radiotelephone system or a radio system. 【0034】 Processing element (or processor) refers to various elements or combinations of elements that are capable of performing functions in a device such as a user device or a cellular network device. Processing elements may include, for example, a processor and associated memory, a part or circuit of an individual processor core, an entire processor core, a processor array, circuits such as an Application Specific Integrated Circuit (ASIC), programmable hardware elements such as a field-programmable gate array (FPGA), and any of the various combinations of the above. 【0035】 Channel - The medium used to transmit information from the transmitter to the receiver. It should be noted that the characteristics of the term "channel" can vary according to different radio protocols; therefore, when used herein, the term "channel" is considered to be used in accordance with the standards of the type of device in which it is used. In some standards, channel width can be variable (depending on, for example, device capabilities, bandwidth conditions, etc.). For example, LTE may support scalable channel bandwidths from 1.4 MHz to 20 MHz. In contrast, a WLAN channel may have a width of 22 MHz, and a Bluetooth channel may have a width of 1 MHz. Other protocols and standards may include different channel definitions. Furthermore, some standards may define and use multiple types of channels, e.g., different channels for uplink or downlink, and / or different channels for different uses such as data, control information, etc. 【0036】 Bandwidth – The term “bandwidth” encompasses the entire range of the ordinary meaning of bandwidth and includes at least a portion of the spectrum (e.g., the radio frequency spectrum) that is used for a particular purpose or set aside for the same purpose. 【0037】 The term "Wi-Fi" (or WiFi) encompasses the full scope of its ordinary meaning and includes, at a minimum, wireless communication networks or RATs that are serviced by wireless LAN (WLAN) access points and provide connectivity to the Internet through these access points. Modern Wi-Fi networks (or WLAN networks) are based on the IEEE 802.11 standard and are marketed under the name "Wi-Fi". Wi-Fi (WLAN) networks are distinct from cellular networks. 【0038】 3GPP access refers to access (e.g., wireless access technology) specified by 3GPP standards. These accesses include, but are not limited to, GSM / GPRS, LTE, LTE-A, and / or 5G NR. In general, 3GPP access refers to various types of cellular access technologies. 【0039】 Non-3GPP access refers to any access not defined by the 3GPP standard (e.g., wireless access technologies). These accesses include, but are not limited to, WiMAX, Wi-Fi, WLAN, and / or fixed networks. Non-3GPP access can be divided into two categories: "trusted" and "untrusted": trusted non-3GPP access can directly interact with the Evolutionary Packet Core (EPC) and / or 5G Core (5GC), while untrusted non-3GPP access interacts with the EPC / 5GC through network entities such as Evolutionary Packet Data Gateways and / or 5G NR Gateways. In general, non-3GPP access refers to various types of non-cellular access technologies. 【0040】 Automatically refers to an action or operation performed by a computer system (e.g., software run by the computer system) or device (e.g., circuitry, programmable hardware element, ASIC, etc.) without user input directly specifying or executing the action or operation. Therefore, the term "automatically" is in contrast to an operation performed or specified manually by the user, where the user provides input to directly execute the operation. An automated procedure may be initiated by user-provided input, but the subsequent actions performed "automatically" are not specified by the user; that is, they are not performed "manually" where the user specifies each action to be performed. For example, a user filling out an electronic form by providing input to select each field and specify the information (e.g., by typing information, selecting checkboxes, selecting radio selections, etc.) is considered manually filling out the form, although the computer system must update the form in response to the user action. A form may also be automatically filled out by a computer system, where the computer system (e.g., software run by the computer system) analyzes the fields of the form and fills it out without user input specifying the answers to the fields. As described above, users can invoke form autofill but do not participate in the actual form completion (for example, the user does not manually specify answers in the fields; rather, the answers are completed automatically). This specification provides various examples of actions that are performed automatically in response to actions taken by the user. 【0041】 "Approximately" refers to a value that is nearly accurate or precise. For example, "approximately" may refer to a value within 1 to 10 percent of a precise (or desired) value. However, it should be noted that the actual threshold (or tolerance) may depend on the application. For example, in some embodiments, "approximately" may mean within 0.1% of a given specified or desired value, while in various other embodiments, the threshold may be, as desired or as required by the particular application, for example, 2%, 3%, 5%, etc. 【0042】 Concurrency refers to parallel execution (execution or performance) in which tasks, processes, or programs are executed at least partially on top of each other. For example, concurrent execution may be performed using "strong" or strict parallelism, where tasks are executed in parallel (at least partially) on each computational element, or it may be performed using "weak parallelism," where tasks are executed interleaved, for example, by time-sharing multiplexing of execution threads. 【0043】 Various components may be described as "configured to" perform a task(s). In such contexts, "configured to" is a broad description that generally means "having a structure" that performs a task(s) or more tasks during operation. Thus, a component may be configured to perform a task even when it is not currently performing that task (for example, a set of conductors may be configured to electrically connect two modules to another even when the two modules are not connected). In some contexts, "configured to" may be a broad description of a structure that generally means "having a circuit" that performs a task(s) or more tasks during operation. Thus, a component may be configured to perform a task even when it is not currently turned on. Generally, the circuit that forms a structure corresponding to "configured to" may include hardware circuitry. 【0044】 For convenience, various components may be described in this specification as performing one or more tasks. Such descriptions should be interpreted as including the phrase “configured to perform.” Descriptions of components configured to perform one or more tasks are expressly intended not to be subject to the interpretation of § 112(f) of the U.S. Patent Act. Figure 1: Communication System 【0045】 Figure 1 shows a simplified, exemplary wireless communication system according to several embodiments. Note that the system in Figure 1 is merely an example of a possible system, and features of this disclosure may be implemented as desired in any of the various systems. 【0046】 As shown in the figure, the exemplary wireless communication system includes one or more user devices 106A, 106B, and so on, up to 106N, and a base station 102A that communicates via a transmission medium. Each of the user devices may be referred to herein as a “user equipment” (UE). Thus, user device 106 is referred to as a UE or UE device. 【0047】 Base station (BS) 102A may be a base transceiver station (BTS) or a cellular base station ("cellular base station"), and may include hardware that enables wireless communication with UE106A~106N. 【0048】 The communication area (or coverage area) of a base station may be referred to as a “cell.” Base stations 102A and UE106 may be configured to communicate over a transmission medium using any of the various radio access technologies (RATs), also known as wireless communication technologies or telecommunications standards, such as LTE, LTE-Advanced (LTE-A), 5G New Radio (5G NR), and Wi-Fi. Note that when base station 102A is implemented in the context of LTE, it may be alternatively referred to as an “eNodeB” or eNB. Note that when base station 102A is implemented in the context of 5G NR, it may be alternatively referred to as a “gNodeB” or “gNB.” 【0049】 As shown in the figure, the base station 102A may also be equipped to communicate with the network 100 (for example, among various possibilities, the core network of a cellular service provider, a telecommunications network such as the Public Switched Telephone Network (PSTN), and / or the Internet). Thus, the base station 102A can facilitate communication between user devices and / or between user devices and the network 100. In particular, the cellular base station 102A can provide the UE 106 with various telecommunications capabilities such as voice, SMS, and / or data services. 【0050】 Base station 102A, and other similar base stations (such as base stations 102B-102N) operating according to the same or different cellular communication standards, may be provided as a network of cells, which can provide continuous or nearly continuous superimposed services over a geographical area to UE106A-106N and similar devices via one or more cellular communication standards. 【0051】 Therefore, as shown in Figure 1, base station 102A can function as a “serving cell” for UEs 106A to 106N, and each UE 106 can also receive signals from one or more other cells (which may be provided by base stations 102B to 102N and / or any other base stations) (within their communication range, if possible). Such cells can also facilitate communication between user devices and / or between user devices and the network 100. Such cells may include “macro” cells, “micro” cells, “pico” cells, and / or cells that provide any other granularity of service area size. For example, base stations 102A to 102B shown in Figure 1 may be macrocells, and base station 102N may be a microcell. Other configurations are also possible. 【0052】 In some embodiments, base station 102A may be a next-generation base station, such as a 5G New Radio (5G NR) base station, or a "gNB". In some embodiments, the gNB may be connected to a conventional evolved packet core (EPC) network and / or an NR core (NRC) network. In addition, a gNB cell may include one or more transition and reception points (TRPs). In addition, UEs capable of operating in accordance with 5G NR may be connected to one or more TRPs in one or more gNBs. 【0053】 In addition, UE 106 may communicate with access point 112 using, for example, wireless networking (e.g., Wi-Fi) and / or peer-to-peer wireless communication protocols (e.g., Bluetooth, Wi-Fi peer-to-peer, etc.). Access point 112 can provide connectivity to network 100. 【0054】 It should be noted that UE106 may be capable of communicating using multiple wireless communication standards. For example, UE106 may be configured to communicate using at least one cellular communication protocol (e.g., LTE, LTE-A, 5G NR, etc.) in addition to wireless networking (e.g., Wi-Fi) and / or peer-to-peer wireless communication protocols (e.g., Bluetooth, Wi-Fi peer-to-peer, etc.). In addition, or alternatively, UE106 may be configured to communicate using one or more Global Navigational Satellite Systems (GNSS, e.g., GPS or GLONASS), one or more mobile television broadcasting standards (e.g., ATSC-M / H or DVB-H), and / or any other wireless communication protocols, if desired. Other combinations of wireless communication standards (including three or more wireless communication standards) are also possible. Figure 2 - Block diagram of a base station 【0055】 Figure 2 shows an exemplary block diagram of a base station 102 according to several embodiments. Note that the base station in Figure 3 is only one example of a possible base station. As shown, the base station 102 includes one or more processors 204 capable of executing program instructions for the base station 102. The processors 204 may also be coupled to a memory management unit (MMU) 240, which may be configured to receive addresses from the processors 204 and translate those addresses to locations in memory (e.g., memory 260 and read-only memory (ROM) 250) or to other circuits or devices. 【0056】 The base station 102 may include at least one network port 270. The network port 270 may be connected to a telephone network and configured to provide multiple devices, such as UE devices 106, with access to the telephone network as described in Figures 1 and 2 above. 【0057】 Network port 270 (or additional network ports) may also, or alternatively, be configured to connect to the cellular network of a cellular service provider's core network. The core network may provide mobility-related services and / or other services to multiple devices, such as UE device 106. In some cases, network port 270 may be connected to a telephone network via the core network, and / or the core network may provide a telephone network (for example, between other UE devices serviced by the cellular service provider). 【0058】 In some embodiments, base station 102 may be a next-generation base station, for example, a 5G New Radio (5G NR) base station, or a "gNB". In such embodiments, base station 102 may be connected to a conventional evolved packet core (EPC) network and / or an NR core (NRC) network. In addition, base station 102 may be considered a 5G NR cell and may include one or more transition and receive points (TRPs). In addition, UEs capable of operating according to 5G NR may be connected to one or more TRPs in one or more gNBs. 【0059】 The base station 102 may include at least one antenna 234, and potentially more antennas. At least one antenna 234 may be configured to operate as a radio transceiver and may be further configured to communicate with the UE device 106 via a radio 230. The antenna 234 communicates with the radio 230 via a communication chain 232. The communication chain 232 may be a receive chain, a transmit chain, or both. The radio 230 may be configured to communicate via a variety of wireless communication standards, including but not limited to 5G NR, LTE, LTE-A, and Wi-Fi. 【0060】 Base station 102 can be configured to communicate using multiple wireless communication standards. In some cases, base station 102 may include multiple radios, which may enable base station 102 to communicate according to multiple wireless communication technologies. For example, one possibility is that base station 102 may include an LTE radio for performing communication according to LTE, and a 5G NR radio for performing communication according to 5G NR. In such a case, base station 102 may be capable of operating as both an LTE base station and a 5G NR base station. Another possibility is that base station 102 may include a multimode radio, which may perform communication according to any of multiple wireless communication technologies (e.g., 5G NR and Wi-Fi, LTE and Wi-Fi, etc.). 【0061】 As further described below in this specification, BS102 may include hardware and software components for implementing or supporting the implementation of the features described herein. The processor 204 of the base station 102 may be configured to implement or support some or all of the methods described herein by executing program instructions stored in a memory medium (e.g., a non-temporary computer-readable memory medium), for example. Alternatively, the processor 204 may be configured as a programmable hardware element such as an FPGA (Field-Programmable Gate Array), or as an ASIC (Application-Specific Integrated Circuit), or a combination thereof. Alternatively (or in addition), the processor 204 of BS102 may be configured to perform or support some or all of the features described herein, together with one or more of the other components 230, 232, 234, 240, 250, 260, 270. 【0062】 In addition, as described herein, the processor(s) 204 may consist of one or more processing elements. In other words, one or more processing elements may be contained within the processor(s) 204. Thus, the processor(s) 204 may include one or more integrated circuits (ICs) configured to perform the functions of the processor(s) 204. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the processor(s) 204. 【0063】 Furthermore, as described herein, the radio 230 may consist of one or more processing elements. In other words, one or more processing elements may be included within the radio 230. Thus, the radio 230 may include one or more integrated circuits (ICs) configured to perform the functions of the radio 230. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the radio 230. Figure 3: Block diagram of the UE 【0064】 Figure 3 shows an exemplary simplified block diagram of a communication device 106 according to several embodiments. Note that the block diagram of the communication device in Figure 3 is only one example of a possible communication device. According to the embodiments, the communication device 106 may be a combination of, among other devices, a User Equipment (UE) device, a mobile device or mobile station, a radio device or radio station, a desktop computer or computing device, a mobile computing device (e.g., a laptop, notebook, or portable computing device), a tablet, an unmanned aerial vehicle (UAV), a UAV controller (UAC), and / or other devices. As shown in the figure, the communication device 106 may include a set of components 300 configured to perform core functions. For example, this set of components may be implemented as a system on a chip (SOC) which may include parts for various purposes. Alternatively, this set of components 300 may be implemented as separate components or groups of components for various purposes. The set of components 300 may be coupled (e.g., directly or indirectly so as to be communicative) to various other circuits of the communication device 106. 【0065】 For example, the communication device 106 may include various types of memory (including, for example, NAND flash 310), an input / output interface such as a connector I / F 320 (for connecting to, for example, a computer system, a dock, a charging station, an input device such as a microphone, a camera, a keyboard, or a speaker), a display 360 which may be integrated with or outside the communication device 106, a cellular communication circuit 330 for 5G NR, LTE, GSM, etc., a short-to-medium-range wireless communication circuit 329 (e.g., Bluetooth® and WLAN circuit), and a wake-up wireless circuit 331. In some embodiments, the communication device 106 may include a wired communication circuit (not shown), such as a network interface card for Ethernet. 【0066】 The cellular communication circuit 330 can be coupled (e.g., directly or indirectly, in a communicative manner) to one or more antennas, such as antennas 335 and 336, as shown in the figure. The short-to-medium range wireless communication circuit 329 can also be coupled (e.g., directly or indirectly, in a communicative manner) to one or more antennas, such as antennas 337 and 338, as shown in the figure. Alternatively, the short-to-medium range wireless communication circuit 329 can be coupled (e.g., directly or indirectly, in a communicative manner) to antennas 335 and 336, in addition to or instead of coupling (e.g., directly or indirectly, in a communicative manner) to antennas 337 and 338. The wake-up wireless circuit 331 can also be coupled (e.g., directly or indirectly, in a communicative manner) to one or more antennas, such as antennas 339a and 339b, as shown in the figure. Alternatively, the wake-up radio circuit 331 may be coupled to antennas 335 and 336 (for example, directly or indirectly, in a communicative manner) in addition to, or instead of, coupling to antennas 339a and 339b (for example, directly or indirectly, in a communicative manner). The short-to-medium-range radio communication circuit 329 and / or cellular communication circuit 330 may include multiple receive chains and / or transmit chains for receiving and / or transmitting multiple spatial streams in a multiple-input multiple output (MIMO) configuration, etc. The wake-up radio circuit 331 may include a wake-up receiver; for example, the wake-up radio circuit 331 may be a wake-up receiver. In some cases, the wake-up radio circuit 331 may be a low-power and / or ultra-low-power wake-up receiver. In some cases, the wake-up radio circuit may be powered / active only when the cellular communication circuit 330 and / or the short-to-medium-range radio communication circuit 329 are in a sleep / no-power / inactive state. In some cases, the wake-up radio circuit 331 may monitor a specific frequency / channel for the wake-up signal (e.g., periodically). Reception of the wake-up signal can trigger the wake-up radio circuit 331 to notify (e.g., directly and / or indirectly) the cellular communication circuit 330 to enter a power-supply / active state. 【0067】 In some embodiments, as further described below, the cellular communication circuit 330 may include dedicated receiving chains for multiple RATs (e.g., a first receiving chain for LTE and a second receiving chain for 5G NR) (e.g., including dedicated processors and / or radios, and / or directly or indirectly coupled to the dedicated processors and / or radios in a communicative manner). In addition, in some embodiments, the cellular communication circuit 330 may include a single transmitting chain that can be switched between radios dedicated to a particular RAT. For example, the first radio may be dedicated to a first RAT, e.g., LTE, and communicate with a dedicated receiving chain and a transmitting chain shared with an additional radio, e.g., a second radio, and the second radio may be dedicated to a second RAT, e.g., 5G NR, and communicate with a dedicated receiving chain and a shared transmitting chain. 【0068】 The communication device 106 may also include and / or be configured for use with one or more user interface elements.

In some embodiments, the UE 106 may include at least two SIMs. Each SIM may perform one or more SIM applications and / or implement SIM functionality. Thus, each SIM may be, for example, a single embeddable smart card that can be soldered onto a circuit board within the UE 106, or each SIM 310 may be implemented as a removable smart card. Therefore, the SIM may be one or more removable smart cards (such as UICC cards, which are sometimes called "SIM cards"), and / or the SIM310 may be one or more embedded cards (for example, embedded UICCs (eUICCs), which are sometimes called "eSIMs" or "eSIM cards"). 【0070】 As shown in the figure, the SOC 300 may include one or more processors 302 capable of executing program instructions for the communication device 106, and a display circuit 304 capable of performing graphics processing and providing display signals to the display 360. The one or more processors 302 may be coupled to a memory management unit (MMU) 340, which may be configured to receive addresses from the one or more processors 302, and to translate those addresses to locations in memory (e.g., memory 306, read-only memory (ROM) 350, NAND flash memory 310), and / or to other circuits or devices such as the display circuit 304, the short-to-medium-range wireless communication circuit 329, the cellular communication circuit 330, the connector I / F 320, and / or the display 360. The MMU 340 may be configured to perform memory protection and page table conversion or setup. In some embodiments, the MMU 340 may be included as part of the one or more processors 302. 【0071】 As described above, the communication device 106 may be configured to communicate using wireless and / or wired communication circuits.

The processor 302 of the communication device 106 may be configured to implement some or all of the features described herein by executing program instructions stored in a memory medium (e.g., a non-temporary computer-readable memory medium). Alternatively (or in addition), the processor 302 may be configured as a programmable hardware element such as a field-programmable gate array FPGA, or as an application-specific integrated circuit (ASIC). Alternatively (or in addition), the processor 302 of the communication device 106 may be configured to implement some or all of the features described herein together with any one or more of the other components 300, 304, 306, 310, 320, 329, 330, 340, 345, 350, 360. 【0073】 In addition, as described herein, the processor 302 may include one or more processing elements. Thus, the processor 302 may include one or more integrated circuits (ICs) configured to perform the functions of the processor 302. In addition, each of the integrated circuits may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the processor(s) 302. 【0074】 Furthermore, as described herein, each of the cellular communication circuit 330 and the short-to-medium range wireless communication circuit 329 may include one or more processing elements. In other words, the cellular communication circuit 330 may include one or more processing elements, and similarly, the short-to-medium range wireless communication circuit 329 may include one or more processing elements. Therefore, the cellular communication circuit 330 may include one or more integrated circuits (ICs) configured to perform the functions of the cellular communication circuit 330. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the cellular communication circuit 330. Similarly, the short-to-medium range wireless communication circuit 329 may include one or more ICs configured to perform the functions of the short-to-medium range wireless communication circuit 329. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the short-to-medium range wireless communication circuit 329. Figure 4 - Block diagram of a modem or baseband processor 【0075】 Figure 4 shows an exemplary block diagram of a modem 400, which may also be referred to as a baseband processor 400, according to several embodiments. The modem 400 may provide signal processing functions for one or more wireless communication technologies, such as Wi-Fi, Bluetooth®, and / or cellular (e.g., 3GPP) communication technologies. Thus, in one possibility, the modem 400 may represent a Wi-Fi modem. For example, the modem 400 shown in Figure 4 may represent one possible example of the Wi-Fi modem 232 shown in Figure 2. In another possibility, the modem 400 may represent a cellular modem or a cellular baseband processor. For example, the modem 400 shown in Figure 4 may represent one possible example of the cellular modem 234 shown in Figure 2. In yet another possibility, the modem 400 may represent a Bluetooth modem. For example, the modem 400 shown in Figure 4 may represent one possible example of the Wi-Fi modem 236 shown in Figure 2. In some embodiments, the modem 400 may implement functions to support communication according to multiple wireless communication technologies. In at least some embodiments, the modem 400 may run a real-time operating system, for example, to facilitate the execution of timing-dependent wireless communication functions. 【0076】 The modem 400 may include a processing circuit 402 which may include one or more processor cores, ASICs, programmable hardware elements, digital signal processors, and / or other processing elements. The processing circuit may be capable of preparing baseband signals for upconversion and transmission by the radio circuit of a wireless device, and / or for processing baseband signals received and downconverted by the radio circuit of a wireless device. Such processing may include signal modulation, coding, decoding, etc., among a variety of possible functions. The processing circuit may similarly or alternatively perform functions for one or more baseband and / or other layers / sublayers of the protocol stack for (one or more) wireless communication technologies implemented by the modem 400, such as physical layer (PHY) functions, media access control (MAC) functions, logic link control (LLC) functions, radio resource control (RRC) functions, and radio link control (RLC) functions. In some embodiments, the modem 400 itself may include at least some radio circuits (for example, for performing the conversion of an input baseband signal to a radio frequency signal, and / or the conversion of an input radio frequency signal to a baseband signal). Alternatively, or in addition, some or all of such functions may be performed by separate radio / transceiver components of the wireless device. 【0077】 The modem 400 may also include a memory 404 which may include a non-temporary computer-readable memory medium. The memory 404 may include program instructions for performing signal processing and / or any of a variety of possible general processing functions. The processing circuit 402 may be capable of executing program instructions stored in the memory 404. The memory 404 may also store data that is generated and / or used during processing performed by the processing circuit 402. 【0078】 As shown in the figures, the modem 400 may further include interface circuits for communicating with other components of the wireless device (such as the STA106 or AP104 shown in Figures 1 to 3), such as an application processor, a wireless / transceiver circuit, and / or various other components. Such interfaces can be implemented in any of several ways. For example, one possibility is that the modem 400 has a direct interface with the transceiver circuit of the wireless device, and an additional indirect interface with the application processor and / or other components of the wireless device via a system bus. Other configurations are also possible. 【0079】 According to at least some embodiments, the hardware and software components of the modem 400 may be configured to implement or support the implementation of features described herein, in particular, among a variety of other possible features, such as performing a method for side-link physical channel expansion for unlicensed spectrum in 5G NR systems and beyond. For example, the processing circuit 402 of the modem 400 may be configured to implement or support some or all of the methods described herein by executing program instructions stored in memory (e.g., a non-temporary computer-readable memory medium) 404, and / or by using dedicated hardware components. Sidelink physical channel expansion 【0080】 The evolution of 3GPP Release 18 sidelinks on unlicensed spectra began with the study and specification of sidelinks on unlicensed spectra for both Mode 1 and Mode 2, where Uu operation for Mode 1 was limited to licensed spectra only. To date, it has been determined that channel access mechanisms from NR-U should be reused for sidelink unlicensed operation. Furthermore, the applicability of sidelink resource reservations from 3GPP Releases 16 and 17 should have been evaluated for their applicability to sidelink unlicensed operation within the boundaries of unlicensed channel access mechanisms and operations. Also to date, it has been determined that physical channel designs require modifications to NR sidelink physical channel structures and procedures to operate on unlicensed spectra, and that existing NR sidelink and NR-U channel structures should be reused as baselines without specific extensions for existing NR SL features. 【0081】 Furthermore, regarding continuous resource block (RB)-based PSCCH / PSSCH transmission in sidelink unauthorized operation (SL-U), it has been agreed that, with respect to subchannels including intra-cell protection band physical RBs (PRBs), such subchannels may be used for PSCCH / PSSCH transmission (note that PRBs within the intra-cell protection band are not used for PSCCH transmission as per previous agreements), or that such subchannels may not be used for PSCCH transmission but may be used for PSSCH transmission. The conditions for applying the above, as well as the definition of candidate resources and their impact on resource selection, remained undetermined. 【0082】 In addition, with respect to sidelink sync signal block (S-SSB) transmission within the RB set, it has been determined that, for 15 kHz and 30 kHz subcarrier spacing (SCS), the frequency domain repetitions will support the transmission of N legacy sidelink primary sync signals (S-PSS) / sidelink secondary sync signals (S-SSS) / physical sidelink broadcast channels (PSBCH), and that there will be a gap between the repetitions and the legacy S-SSB transmissions to satisfy the occupied channel bandwidth (OCB) requirements. It remained undecided whether the length of the gap between repetitions is (pre)configured or predefined, the value of N, whether the peak-to-average power ratio (PAPR) will be reduced and / or how it will be reduced, and whether there may be no gap at all. 【0083】 Furthermore, for physical sidelink feedback channel (PSFCH) transmissions using 15kHz and 30kHz SCS, it has been decided to support one or more of the following: each PSFCH transmission occupies one common interlace and a K3 dedicated PRB (K3 is (pre)configured), each PSFCH transmission occupies one dedicated interlace, or each PSFCH transmission occupies a K4 dedicated PRB and a K2 common PRB, with the K2 common PRB located at two edges of the RB set (K2 is set to a value of 2 and K4 is (pre)configured). However, whether or not an in-band radiation (IBE) problem exists, and whether or not such a problem will be addressed and / or how it will be addressed, for example, whether or not a protected band PRB / resource element (RE) will be introduced between the common PRB and the dedicated PRB, remains undecided beyond which of the above will be used. 【0084】 Therefore, improvement is desired. 【0085】 The embodiments described herein provide systems, methods, and mechanisms for sidelink physical channel expansion for unlicensed spectra, including subchannels with overlapping protection bands for PSCCH / PSSCH transmission, S-SSB repetition in SL-U, PSFCH with a gap between a common PRB and a dedicated PRB, and systems, methods, and mechanisms for PSCCH and PSSCH resource mapping. 【0086】 For example, in some cases, assuming that the number of (pre-)configured PSCCHs is N PRBs for a subchannel with overlapping protection bandwidth for PSCCH / PSSCH transmission, in continuous RB-based PSCCH / PSSCH transmission in SL-U, the subchannel can be used for PSCCH / PSSCH transmission if the total number of PRBs in the subchannels that do not overlap with the protection bandwidth is N or greater. Otherwise, the subchannel can be used for PSSCH transmission but not for PSCCH transmission. For example, Figure 5A shows an example of multiple resource blocks spanning multiple subchannels with overlapping protection bandwidth according to one embodiment. As shown, the first RB set (e.g., RB set #1) may include subchannels 1, 2, and 3 and a portion of subchannel 4. The portion of subchannel 4 included in the first RB set may include A RBs. Similarly, the second RB set (e.g., RB set 2) may include a portion of subchannel 5 and subchannels 6, 7, and 8. A portion of subchannel 5 included in the second RB set may contain B RBs, as shown. Furthermore, the protection bandwidth may extend over a portion of subchannel 4 and a portion of subchannel 5. Thus, in some cases, when A is greater than or equal to the number of (pre)configured PSCCHs, e.g., N, subchannel 4 may be used for PSCCH / PSSCH transmission. Otherwise, subchannel 4 cannot be used for PSCCH / PSSCH transmission. Similarly, in some cases, when B is greater than or equal to the number of (pre)configured PSCCHs, e.g., N, subchannel 5 may be used for PSCCH / PSSCH transmission. Otherwise, subchannel 5 cannot be used for PSCCH / PSSCH transmission. As another example, Figure 5B shows an example of a single subchannel containing a protection bandwidth according to several embodiments. As shown, a subchannel (e.g., subchannel 0) may contain three parts. The first portion, starting from the beginning of the subchannel, may contain C RBs; the second portion following the first portion may contain a protection band; and the third portion following the second portion may contain D RBs.Therefore, in some cases, if the sum of C and D is greater than or equal to the number of (pre-)configured PSCCHs, e.g., N, then subchannel 0 can be used for PSCCH / PSSCH transmission. Otherwise, subchannel 4 cannot be used for PSCCH / PSSCH transmission. 【0087】 As another example, in some cases, for a subchannel with overlapping protection bandwidth for PSCCH / PSSCH transmission, assuming that the number of (pre-)configured PSCCHs is N PRBs, in continuous RB-based PSCCH / PSSCH transmission in SL-U, the subchannel can be used for PSCCH / PSSCH transmission if the first N PRBs in the subchannel do not overlap with the protection bandwidth. Otherwise, the subchannel can be used for PSSCH transmission but cannot be used for PSCCH transmission. Returning to the example in Figure 5A, in some cases, when A is greater than or equal to the number of (pre-)configured PSCCHs, e.g., N, subchannel 4 can be used for PSCCH / PSSCH transmission. Otherwise, subchannel 4 cannot be used for PSCCH / PSSCH transmission. Furthermore, since subchannel 5 starts with the protection bandwidth, subchannel 5 cannot be used for PSCCH / PSSCH transmission. Similarly, returning to Figure 5B, in some cases, subchannel 0 cannot be used for PSCCH / PSSCH transmission unless C is greater than or equal to the number of (pre-)configured PSCCHs, e.g., N. 【0088】 As another example, in some cases, with respect to S-SSB repetitions in an SL-U where each S-SSB occupies 11 PRBs and each RB set has a bandwidth of 20 megahertz (MHz), the legacy S-PSS / S-SSS / PSBCH may be transmitted N times by repetitions in the frequency domain with gaps between repetitions to satisfy the OCB requirement. In some cases, the two S-SSBs may always be configured at the edge of the SL bandwidth portion (BWP) or SL resource pool, as shown, for example, by Figure 6A. Thus, the length of the gap may be predefined between the two S-SSB repetitions. For example, to indicate the location of the second S-SSB, a sidelink frequency configuration information element (IE), such as SL-FreqConfig, may be extended and / or modified to include parameters such as an additional sl-AbsoluteFreqeuncySSB_2 parameter. In other cases, the gap from the S-SSB start PRB to the RB set start PRB may be (pre)configured and / or (pre)defined, for example, as shown in Figure 6B. In such cases, the gap from the S-SSB iteration end PRB to the RB set end PRB may have the same value or a different value (which may also be (pre)configured and / or (pre)defined). In addition, in such cases, the gap between the two S-SSBs may be determined autonomously. In yet another case, the gap from the S-SSB end PRB to the S-SSB iteration start PRB may be (pre)configured, for example, as shown in Figure 6C. Furthermore, the gap from the S-SSB start PRB to the RB set start PRB may be (pre)configured and / or (pre)defined. 【0089】 As further examples, in some cases, the PSFCH resource, gap, may be included between a common PRB and a dedicated PRB, for example, as illustrated by Figure 7. In some cases, the gap may help avoid IBE from a common PRB to a dedicated PRB. In some cases, the gap may be (pre)configured. In some cases, the configuration of a dedicated PRB PSFCH may be restricted (e.g., not all PRBs are suitable for a dedicated PRB). For example, both the upper and lower bounds of the bitmap for a dedicated PRB may be restricted. In some cases, the bitmap may be of a length equal to the number of PRBs in the RB set. However, the first X bits and the last X bits in the bitmap may be 0 (e.g., not used for a dedicated PRB). In other cases, the bitmap may be 2X less in length than the number of PRBs, where X may be (pre)defined (e.g., 5 or 10 PRBs). 【0090】 As a further example, in some cases, for PSCCH and PSSCH resource mappings, multiple interlace mappings may be performed for OFDM symbols on a per-subchannel basis for both PSCCH and PSSCH. In some cases, as shown in Figure 8A, the mapping may follow a frequency priority rule. In such cases, note that the modulation symbols may be placed on the lowest unoccupied frequency PRB of the subchannel. In other cases, as shown in Figure 8B, the mapping may follow an interlace priority rule. In such cases, note that the modulation symbols may be placed on the lowest unoccupied frequency PRB of the lowest interlace of the subchannel. The mapping can then continue on the next unoccupied interlace. 【0091】 As yet another example, in some cases, for PSCCH resource mapping, for OFDM symbols with multiple subchannels during transmission, the interlaced mapping may follow a subchannel priority rule, a frequency priority rule, or an interlaced priority rule. In some cases, for example, as shown in Figure 9A, the mapping may follow a subchannel priority rule that incorporates a frequency priority rule. The mapping may start with the lowest subchannel according to the frequency priority rule, followed by the next lowest subchannel according to the frequency priority rule. In some cases, the mapping may follow a subchannel priority rule that incorporates an interlaced priority rule. The mapping may start with the lowest subchannel according to the interlaced priority rule, followed by the next lowest subchannel according to the interlaced priority rule. In some cases, the mapping may follow a frequency priority rule, and the modulation symbol may be placed on the lowest unoccupied frequency PRB of all PRBs used for transmission across multiple subchannels. In some cases, for example, as shown in Figure 9B, the mapping may follow an interlace priority rule, starting at the lowest interlace for transmission and continuing at the next lowest interlace for transmission. 【0092】 Figure 10 shows a block diagram of an example of a method for transmitting a sidelink physical channel with protection bandwidth overlap in an SL-U, according to several embodiments. The method shown in Figure 10 can be used in conjunction with any of the systems, methods, or devices shown in the figure, among other devices. For example, the processor (such as the baseband processor 400 shown and described in relation to Figure 4) and / or other hardware of such a device may be configured to cause the device to execute any combination of the method elements shown in the figure and / or other method elements. In various embodiments, some of the illustrated method elements may be executed simultaneously, in a different order than shown, or omitted. Additional method elements may be executed as needed. As shown in the figure, this method may operate as follows: 【0093】 In 1002, a UE such as UE106 may determine, with respect to continuous resource block (RB)-based sidelink physical channel transmission in the SL-U, whether a subchannel can be used for sidelink physical channel transmission based on conditions associated with the number of physical resource blocks (PRBs) configured for the sidelink physical channel. In some cases, the sidelink physical channel may be a PSCCH or a PSSCH. 【0094】 In 1004, the UE may transmit the sidelink physical channel depending on whether it has determined that the condition is met. In some cases, the condition may be that the total number of PRBs in subchannels that do not overlap with the protection band is greater than or equal to the number of PRBs configured for the sidelink physical channel. In some cases, the condition may be that a portion of the PRBs at the beginning of subchannels that do not overlap with the protection band is greater than or equal to the number of PRBs configured for the sidelink physical channel. 【0095】 In some cases, the UE may transmit a first type of sidelink physical channel and is prohibited from transmitting a second type of sidelink physical channel when the conditions are not met. The first type of sidelink physical channel may be a PSSCH, and the second type of sidelink physical channel may be a PSCCH. 【0096】 In some cases, the protection bandwidth extends to the two subchannels. In other cases, the protection bandwidth can be within a single subchannel. 【0097】 In some cases, a UE may use either a frequency-first interlacing rule or an interlacing-first interlacing rule, e.g., a first interlacing rule, for each orthogonal frequency division multiplexing (OFDM) symbol for multiple interlaces per subchannel. In addition, to interlace multiple subchannels in transmission, a UE may use either a subchannel-first interlacing rule, a frequency-first interlacing rule, or an interlacing-first interlacing rule, e.g., a second interlacing rule, for OFDM symbols. 【0098】 In some cases, multiple interlacing per subchannel may be applied to both the first type and the second type of sidelink physical channel, and multiple subchannel interlacing in transmission may be applied to the first type of sidelink physical channel but not to the second type of sidelink physical channel. The first type may be PSCCH and the second type may be PSSCH. 【0099】 In some cases, with multiple interlacing per subchannel and under frequency-first interlacing rules, the modulation symbol may be placed on the lowest unoccupied frequency physical resource block of the subchannel. 【0100】 In some cases, for interlacing multiple subchannels in transmission, under a subchannel-first interlacing rule, the mapping may start from the lowest subchannel, with the modulation symbol placed on the lowest unoccupied frequency physical resource block of the subchannel according to a frequency-first interlacing rule, or on the lowest unoccupied frequency physical resource block of the subchannel's lowest interlacing according to an interlacing-first interlacing rule. In some cases, for interlacing multiple subchannels in transmission, under a frequency-first interlacing rule, the modulation symbol may be placed across multiple subchannels on the lowest unoccupied frequency PRB among all physical resource blocks (PRBs) used for transmission. In some cases, for interlacing multiple subchannels in transmission, under an interlacing-first interlacing rule, the mapping may start from the lowest interlacing for transmission and continue to the next lowest interlacing for transmission. 【0101】 Figure 11 shows a block diagram of an example of a method for a sidelink synchronization signal block (S-SSB) in an SL-U according to several embodiments. The method shown in Figure 11 can be used in conjunction with any of the systems, methods, or devices shown in the figure, among other devices. For example, the processor (such as the baseband processor 400 shown and described in relation to Figure 4) and / or other hardware of such a device may be configured to cause the device to execute any combination of the method elements shown in the figure and / or other method elements. In various embodiments, some of the illustrated method elements may be executed simultaneously, in a different order than those shown, or omitted. Additional method elements may be executed as needed. As shown in the figure, the method may operate as follows: 【0102】 In 1102, a UE such as UE 106 may configure the transmit bandwidth to satisfy the occupied channel bandwidth (OCB) requirement. 【0103】 In 1104, the UE can transmit S-SSB in a configured number of repetitions in the frequency domain, with gaps between repetitions to satisfy the OCB requirements. 【0104】 In some cases, S-SSB repeats may be configured at the edges of the sidelink bandwidth portion / sidelink resource pool, and the S-SSB configuration may predefine the gaps between S-SSB repeats. In some cases, the first parameter in the SL-FreqConfig information element may indicate the location of the first S-SSB repeat in the sidelink bandwidth portion / sidelink resource pool, and the second parameter in the SL-FreqConfig information element may indicate the location of the second S-SSB repeat in the sidelink bandwidth portion / sidelink resource pool, thereby configuring the gap between the first and second S-SSB repeats. 【0105】 In some cases, a first gap can be configured or defined between the starting physical resource block (RB) of an S-SSB iteration and the RB start PRB. A second gap can also be configured or defined between the ending RB of an S-SSB iteration and the RB set end PRB. In some cases, the first and second gaps may be equal to the second gap. In other cases, the first gap may not be equal to the second gap. In some cases, the UE can determine the gap between S-SSB iterations based on the first and second gaps. 【0106】 In some cases, the gap between S-SSB iterations can be constructed or defined. 【0107】 Figure 12 shows a block diagram of an example of a method for specifying the gap between a common PRB and a dedicated PRB for PSFCH transmission in an SL-U, according to several embodiments. The method shown in Figure 12 can be used in conjunction with any of the systems, methods, or devices shown in the figure, among other devices. For example, the processor (such as the baseband processor 400 shown and described in relation to Figure 4) and / or other hardware of such a device may be configured to cause the device to execute any combination of the method elements shown in the figure and / or other method elements. In various embodiments, some of the illustrated method elements may be executed simultaneously, in a different order than shown, or omitted. Additional method elements may be executed as needed. As shown in the figure, this method may operate as follows: 【0108】 In 1202, UEs such as UE106 may form a gap between the common PRB and the dedicated PRB to avoid in-band radiation (IBE) from the common PRB to the dedicated PRB. 【0109】 In 1204, the UE may transmit the PSFCH using the gap between the common PRB and the dedicated PRB. 【0110】 In some cases, the bitmap specifying the configuration may conform to upper and lower limits for dedicated PRBs. In some cases, to conform to the upper and lower limits, the bitmap may contain the number of bits configured at the beginning and end of resource blocks, which are set to a value of 0. In such cases, the length of the bitmap may be equal to the total number of PRBs in the resource block set. In some cases, to conform to the upper and lower limits, the length of the bitmap may be set to a length less than the total number of PRBs in the resource block set. In such cases, the length of the bitmap is determined by reducing the total number of PRBs by twice a defined value, which may be specified by the standard. 【0111】 Figure 13 shows a block diagram of an example of a method for sidelink physical channel resource mapping in an SL-U according to several embodiments. The method shown in Figure 13 can be used in conjunction with any of the systems, methods, or devices shown in the figure, among other devices. For example, the processor (such as the baseband processor 400 shown and described in relation to Figure 4) and / or other hardware of such a device may be configured to cause the device to execute any combination of the method elements shown in the figure and / or other method elements. In various embodiments, some of the illustrated method elements may be executed simultaneously, in a different order than those shown, or omitted. Additional method elements may be executed as needed. As shown in the figure, this method may operate as follows: 【0112】 In 1302, a UE such as UE106 may use one of either a frequency-first interlacing rule or an interlacing-first interlacing rule, for example, the first interlacing rule, for each orthogonal frequency division multiplexing (OFDM) symbol for multiple interlaces per subchannel. 【0113】 In 1304, the UE may use one of the following rules for OFDM symbols to interlace multiple subchannels in transmission: a subchannel-first interlacing rule, a frequency-first interlacing rule, or an interlacing-first interlacing rule, such as a second interlacing rule. 【0114】 In some cases, multiple interlacing per subchannel may be applied to both the first type and the second type of sidelink physical channel, and multiple subchannel interlacing in transmission may be applied to the first type of sidelink physical channel but not to the second type of sidelink physical channel. The first type may be PSCCH and the second type may be PSSCH. 【0115】 In some cases, with multiple interlacing per subchannel, and under frequency-first interlacing rules, modulation symbols may be placed on the lowest unoccupied frequency physical resource block of the subchannel. 【0116】 In some cases, with multiple interlacing per subchannel, and under interlacing-first interlacing rules, the modulation symbols may be placed on the lowest unoccupied frequency physical resource block of the lowest interlacing subchannel. 【0117】 In some cases, to interlace multiple subchannels in transmission, under subchannel-first interlacing rules, the mapping may start from the lowest subchannel, with the modulation symbols placed on the lowest unoccupied frequency physical resource block of the subchannel according to frequency-first interlacing rules, or the modulation symbols placed on the lowest unoccupied frequency physical resource block of the lowest interlaced subchannel according to interlacing-first interlacing rules. 【0118】 In some cases, in order to interlace multiple subchannels in transmission, under the frequency-priority interlacing rule, the modulation symbol may be placed on the lowest unoccupied frequency PRB among all physical resource blocks (PRBs) used for transmission across multiple subchannels. 【0119】 In some cases, to interlace multiple subchannels in transmission, under interlace priority interlacing rules, the mapping may start with the lowest interlace for transmission and continue with the next lowest interlace for transmission. 【0120】 In some cases, the UE may determine whether a subchannel can be used for sidelink physical channel transmission based on a condition associated with the number of physical resource blocks (PRBs) configured for the sidelink physical channel, for continuous resource block (RB)-based sidelink physical channel transmission in the SL-U. In some cases, the sidelink physical channel may be a PSCCH or a PSSCH. In addition, the UE may transmit the sidelink physical channel depending on whether it determines that the condition is met. In some cases, the condition may be that the total number of PRBs in a subchannel that does not overlap with the protection bandwidth is greater than or equal to the number of PRBs configured for the sidelink physical channel. In some cases, the condition may be that a portion of the PRBs at the beginning of a subchannel that does not overlap with the protection bandwidth is greater than or equal to the number of PRBs configured for the sidelink physical channel. Furthermore, when the condition is not met, the UE may transmit the first type of sidelink physical channel, and the transmission of the second type of sidelink physical channel is prohibited. The first type of sidelink physical channel may be a PSSCH, and the second type of sidelink physical channel may be a PSCCH. The protection bandwidth may extend to portions of two subchannels, and / or the protection bandwidth may be within a subchannel. 【0121】 It should be fully understood that the use of personally identifiable information should adhere to privacy policies and practices that are generally recognized as meeting or exceeding industry or government requirements for maintaining user privacy. In particular, personally identifiable information data should be managed and handled in a manner that minimizes the risk of unintended or unauthorized access or use, and the nature of authorized use should be clearly indicated to the user. 【0122】 Embodiments of the present disclosure can be implemented in various forms. For example, some embodiments may be implemented as a method executed by a computer, on a computer-readable storage medium, or on a computer system. Other embodiments may be implemented using one or more custom-designed hardware devices, such as ASICs. Still other embodiments may be implemented using one or more programmable hardware elements, such as FPGAs. 【0123】 In some embodiments, a non-temporary computer-readable memory medium may be configured to store program instructions and / or data, which, when executed by a computer system, cause the computer system to execute the Method, for example, any embodiment of the Method described herein, a combination of embodiments of the Method described herein, a subset of embodiments of the Method described herein, or a combination of such subsets. 【0124】 In some embodiments, the device (e.g., UE 106) may be configured to include a processor (or a set of processors) and a storage medium, the storage medium storing program instructions, and the processor is configured to read and execute program instructions from the storage medium, the program instructions being executable to implement various method embodiments described herein (or combinations of method embodiments described herein, or subsets of method embodiments described herein, or combinations of such subsets). The device may be implemented in any of the various forms. 【0125】 Any of the methods described herein for operating user equipment (UE) can form the basis for a corresponding method for operating a base station by interpreting each message / signal X received by the UE on the downlink as a message / signal X transmitted by the base station, and each message / signal Y transmitted by the UE on the uplink as a message / signal Y received by the base station. 【0126】 Although the embodiments described above are described in considerable detail, numerous variations and modifications will become apparent to those skilled in the art if the above disclosure is fully understood. The following claims are intended to be construed as encompassing all such variations and modifications.
