Description

Technical Field

[0001] This application relates to the field of wireless communication systems or networks, and more specifically, to a scheme for wireless communication between user equipment in a wireless communication system using dedicated communication resources for communication related to at least one communication service provided by a base station and / or a network. The at least one communication service may be permanently or conditionally available, i.e., it may only be available if at least one predetermined condition is met. Implementations and some non-limiting embodiments may relate to improvements and enhancements for pedestrian UEs in communication environments related to vehicle-to-everything (V2X) services. Background Technology

[0002] like Figure 1A As shown, Figure 1A and Figure 1B It includes the core network 102 and one or more radio access networks RAN1, RAN2, ... RAN N A schematic representation of an embodiment of a terrestrial wireless network 100. Figure 1B It can be a radio access network (RAN) that may include one or more base stations gNB1 to gNB5. n The embodiments are illustrative representations, where each base station serves a designated area surrounding the base station, illustratively represented by corresponding cells 1061 to 1065. The base station provides services to users within the cell. The term base station (BS) refers to a gNB in ​​a 5G network, an eNB in ​​the UMTS / LTE / LTE-A / LTE-A protocol, or simply a BS in other mobile communication standards. Users can be static or mobile devices. Wireless communication systems can also be accessed via mobile or static Internet of Things (IoT) devices connected to the base station or the user. Mobile devices or IoT devices can include physical devices, ground-based vehicles such as robots or cars, aircraft such as manned or unmanned aerial vehicles (UAVs) (UAVs are also called drones), mobile machines, smart devices like smartwatches, buildings, and other items or devices that embed electronics, software, sensors, actuators, etc., and network connections that enable these devices to collect data and exchange data over existing network infrastructure.

[0003] It should be noted that the embodiments are not limited to terrestrial wireless networks, but network entities can involve non-terrestrial networks (NTNs), wherein the parts of the BS and / or the BS and / or the core network can be payloads of satellites (LEO, GEO, MEO) or high-altitude platforms (HAPs), such as balloons or special aircraft.

[0004] Figure 1B An exemplary diagram of five cells is shown; however, RAN n It can include more or less such cells, and RANn It can also include only one base station. Figure 1B Two users, UE1 and UE2, are shown, also referred to as user equipment UEs located in cell 1062 and served by base station gNB2. Another user, UE3, is shown in cell 1064 served by base station gNB4. Arrows 1081, 1082, and 1083 schematically represent uplink / downlink connections used to transmit data from users UE1, UE2, and UE3 to base stations gNB2 and gNB4, or to transmit data from base stations gNB2 and gNB4 to users UE1, UE2, and UE3. Furthermore, Figure 1B Two IoT devices, 1101 and 1102, located in cell 1064 are shown; these can be stationary or mobile devices. As schematically indicated by arrow 1121, IoT device 1101 accesses the wireless communication system via base station gNB4 to receive and transmit data. As schematically indicated by arrow 1122, IoT device 1102 accesses the wireless communication system via user UE3. The corresponding base stations gNB1 through gNB5 can be connected to... Figure 1B The arrow pointing to the "core" schematically represents the core network 102, for example, via the S1 interface and corresponding backhaul links 1141 to 1145. Core network 102 can connect to one or more external networks and the Internet. Furthermore, some or all of the corresponding base stations gNB1 to gNB5 can connect via... Figure 1B The arrow pointing to "gNB" schematically indicates that the corresponding backhaul links 1161 to 1165 are connected to each other, for example, via the S1 or X2 interface or the XN interface in the NR. The network can also contain direct-mode UE communication, also known as device-to-device (D2D) communication. This interface is often referred to as the PC5 interface.

[0005] Data transmission can be performed using a physical resource grid. A physical resource grid can include a set of resource elements that map various physical channels and physical signals to that set of resource elements. For example, physical channels can include physical downlink, uplink, and sidelink shared channels (PDSCH, PUSCH, PSSCH) carrying user-specific data (also known as downlink, uplink, and sidelink payload data); physical broadcast channels (PBCH) carrying, for example, Master Information Block (MIB) and System Information Block (SIB); and physical downlink, uplink, and sidelink control channels (PDCCH, PUCCH, PSSCH) carrying, for example, downlink control information (DCI), uplink control information (UCI), and sidelink control information (SCI). For the uplink, once the UE is synchronized and has acquired the MIB and SIB, the physical channels can further include the physical random access channel (PRACH or RACH) used by the UE to access the network. Sidelinks can also include physical sidelink feedback channels (PSFCH). Physical signals can include reference signals or symbols (RS), synchronization signals, etc. A resource grid can include frames or radio frames that have a specific duration in the time domain and a given bandwidth in the frequency domain. A frame can have a specific number of subframes of a predetermined length, for example, 1 ms. Each subframe can include 12 or 14 OFDM symbols in one or more time slots, depending on the cyclic prefix (CP) length. For example, a frame can also consist of an even smaller number of OFDM symbols when utilizing a shortened transmission time interval (sTTI) or a micro-slotted / non-slotted frame structure that includes only a small number of OFDM symbols.

[0006] Wireless communication systems can be any single-tone system or a multi-carrier system using frequency division multiplexing, such as orthogonal frequency division multiplexing (OFDM) systems, orthogonal frequency division multiple access (OFDMA) systems, or any other IFFT-based system with or without CP, such as DFT-s-OFDM. Other waveforms can be used, such as non-orthogonal waveforms for multiple access, such as filter bank multicarrier (FBMC), universal frequency division multiplexing (GFDM), or universal filtered multicarrier (UFMC). Wireless communication systems can operate according to, for example, advanced LTE protocol standards or 5G or NR, new radio standards or NR-U, new unlicensed radio standards or NR-NTN, non-terrestrial network standards or 3GPP UAV, unlicensed aircraft standards or IoT, Internet of Things standards or 802.11ax or 802.11be specifications.

[0007] Figure 1A and Figure 1BThe wireless network or communication system described herein can be a heterogeneous network with different coverage networks, such as a macro cell network, and each macro cell includes a network of macro base stations, such as base stations gNB1 to gNB5, and small cell base stations. Figure 1A and Figure 1B (as shown in the diagram), such as a femtocell or picocell.

[0008] In addition to the aforementioned terrestrial wireless networks, there exist non-terrestrial wireless communication networks that include space-borne transceivers, such as satellites, and / or non-terrestrial wireless communication networks that include airborne transceivers, such as unmanned aerial systems. Non-terrestrial wireless communication networks or systems can be referenced in the above-mentioned... Figure 1A and Figure 1B The ground systems described above operate in a similar manner, for example, according to the Advanced LTE protocol standard or the new 5G or NR radio standard.

[0009] In mobile communication networks, for example, as referenced above... Figure 1A and Figure 1B In the aforementioned networks, such as LTE or 5G / NR networks, there may be UEs that communicate directly with each other via one or more sidelink (SL) channels, for example, using the PC5 interface. UEs that communicate directly with each other via sidelinks can include vehicles communicating directly with other vehicles (V2V communication), vehicles communicating with other entities in the wireless communication network (e.g., roadside entities such as traffic lights and traffic signs) (V2I communication), and vehicles communicating directly with pedestrians (V2P communication) (also referred to as pedestrian UEs (P-UEs)). Other UEs may not be vehicle-related UEs and may include any of the devices mentioned above. These devices may also communicate directly with each other using the SL interface and its defined channels (D2D communication).

[0010] When considering two UEs that communicate directly with each other via a sidelink, the two UEs can serve the same base station, allowing the base station to provide sidelink configuration, resource allocation, or assistance to the UEs. For example, the two UEs can be located at a base station (such as...). Figure 1B The scenario described above refers to the coverage area of ​​a base station. This is called the "in-coverage" scenario. Another scenario is called the "out-of-coverage" scenario. It should be noted that "out-of-coverage" does not mean that the two UEs are not located within the coverage area of ​​a base station. Figure 1B The text does not refer to a single cell, but rather to these UEs:

[0011] The UE may not be connected to a base station, for example, it may not be in an RRC connected or RRC deactivated state, therefore, the UE does not receive any sidelink configuration, resource allocation, or assistance from the base station; and / or

[0012] It can connect to the base station; however, for one or more reasons, the base station cannot provide the UE with sidelink configuration, resource allocation, or assistance; and / or

[0013] It can connect to base stations that do not support NR V2X services, such as GSM, UMTS, LTE base stations, or WiFi access points.

[0014] When considering two UEs that communicate directly with each other via a sidelink, for example using a PC5 interface, one UE can also connect to a BS and relay information from the BS to other UEs via the sidelink interface. Relay can be performed in the same frequency band (in-band relay) or in another frequency band (out-of-band relay). In the first case, different time slots can be used in a time-division duplex (TDD) system to decouple communication on the UE and the sidelink.

[0015] Figure 2 This is a schematic representation of an in-coverage scenario where two UEs, 202 and 204, communicating directly with each other are connected to base station 201. Base station gNB 201 has a coverage area schematically represented by circle 200, which is essentially... Figure 1B The cell correspondence is schematically represented in the diagram. UEs 202 and 204 that communicate directly with each other can include both a first vehicle 202 (also referred to as a vehicle UE or V-UE) and a second vehicle 204 (also referred to as a vehicle UE or V-UE) located in the coverage area 200 of base station gNB 201. The two vehicle UEs 202 and 204 are connected to base station gNB 201, and furthermore, they are directly connected to each other via their PC5 interfaces. V2V traffic scheduling and / or interface management are assisted by control signaling on the Uu interface (i.e., the radio interface between base station 201 and UEs 202 and 204) of gNB 201. In other words, gNB 201 provides SL configuration, resource allocation, or assistance to UEs 202 and 204, and gNB 201 allocates resources used for V2V communication via sidelinks. This configuration is also referred to as Mode 1 configuration in NR V2X or Mode 3 configuration in LTE V2X.

[0016] Figure 3This is an illustrative representation of an out-of-coverage scenario, in which, although they may be physically located within a cell and thus within the coverage of a base station of a wireless communication network, UEs 206, 208, and 210 communicating directly with each other are not connected to the base station, or some or all of UEs 206, 208, and 210 communicating directly with each other are connected to the base station, but the base station does not provide any SL configuration, resource allocation, or assistance. Three vehicle UEs 206, 208, and 210 communicating directly with each other via sidelinks are shown, for example, using the PC5 interface. The scheduling and / or interface management of V2V traffic is based on an algorithm implemented between vehicle UEs 206, 208, and 210. This configuration is also referred to as Mode 2 configuration in NR V2X or Mode 4 configuration in LTE V2X. As mentioned above, Figure 3 The scenario described, namely, the out-of-coverage scenario, does not necessarily refer to the corresponding Mode 2 UE (in NR) or Mode 4 UE (in LTE) being located outside the base station's coverage area. Rather, it refers to the corresponding Mode 2 UE (in NR) or Mode 4 UE (in LTE) not being served by the base station, not being connected to the base station in the coverage area, or being connected to the base station but not receiving SL configuration, resource allocation, or assistance from the base station. Therefore, situations may exist where, in Figure 2 Within the coverage area 200 shown, in addition to NR mode 1 or LTE mode 3 UEs 202 and 204, there are also NR mode 2 or LTE mode 4 UEs 206, 208 and 210.

[0017] It should be noted that the information in the foregoing section is only intended to enhance the understanding of the background of the present invention, and therefore may contain information that does not constitute prior art known to those skilled in the art.

[0018] Starting with the aforementioned existing technology, there may be a need for improvements in resource allocation for communication in the side link. Attached Figure Description

[0027] Figure 7 This is a schematic representation illustrating the method according to the present invention. Detailed Implementation

[0028] In the following description, equivalent or identical reference numerals are used to denote one or more equivalent or identical elements having the same or identical functions.

[0029] The method steps depicted and described by reference to the block diagrams may also be performed in an order different from the order depicted and / or described. Furthermore, method steps relating to specific features of the device may be replaced by those features, as well as other surrounding factors.

[0030] It is possible Figure 1A , Figure 1B , Figure 2 ,as well as Figure 3 The embodiments of the present invention are implemented in wireless communication systems including base stations and users (such as mobile terminals or IoT devices) as described herein. Figure 4 It includes a transmitter 300 (such as a base station) and one or more receivers 3021 to 302. n This is a schematic representation of a wireless communication system (such as a user equipment, UE). Transmitter 300 and receiver 302 can communicate via one or more wireless communication links or channels 304a, 304b, 304c (such as radio links). Transmitter 300 may include one or more antennas ANT. T Alternatively, it may include an antenna array with multiple antenna elements coupled to each other, a single processor 300a, and a transceiver 300b. The receiver 302 includes one or more antennas ANT. R Or an antenna array with multiple antennas coupled to each other, a single processor 302a1, 302a n and transceivers 302b1 and 302b nBase station 300 and UE 302 can communicate via corresponding first wireless communication links 304a and 304b (e.g., radio links using Uu interfaces), while UE 302 can communicate with each other via a second wireless communication link 304c (e.g., radio links using PC5 interfaces). When a UE is not served by the base station or is not connected to the base station, for example, when it is not in an RRC connection state, or more generally, when the base station does not provide SL configuration, resource allocation, or assistance, the UEs can communicate with each other via sidelinks. The system, one or more UEs 302, and the base station can operate in accordance with the teachings of the invention described herein.

[0031] The concepts described herein may relate to communication between user equipment, referred to as user equipment (UE), wherein the communication between two UEs may also be referred to as device-to-device (D2D) communication, or the communication between at least one UE and a network entity (e.g., a base station) may also be referred to as cellular communication. According to the concepts, a UE can participate in communication related to a first service (e.g., a D2D communication type) and communication related to different second services (e.g., a cellular communication type). As a non-limiting embodiment of the concepts described herein, at least one communication service may include, for example, D2D communication between a UE and at least one other UE via a side link. As a non-limiting embodiment of the concepts described herein, the second service may include cellular communication via, for example, a Uu link, such as communication between a UE and a base station. As a non-limiting embodiment of at least one communication service, a vehicle-to-everything (V2X) communication scenario between a vehicle UE and a non-vehicle UE can be described. As a non-limiting embodiment of a non-vehicle UE, a so-called pedestrian UE (P-UE) may be mentioned herein. Of course, other D2D communications are possible, and other types of UEs, such as (Internet of Things) devices, robots, drones, and many others, can adopt the concepts described herein.

[0032] In the non-limiting case of at least one communication service, multiple such UEs can constitute a user equipment group, also simply referred to as a packet, and can perform intra-packet or inter-packet communication via a sidelink interface between user equipments (such as a PC5 interface). Thus, the concept described herein supports not only direct D2D communication, but also broadcast, UE-wide addressing, or multicast communication. In multicast communication, a UE can use a dedicated packet ID to directly transmit information to a group of UEs within its communication range.

[0033] For example, the scenario described herein, using specific UEs employing the first and second services, can be adopted in the transportation industry. In this scenario, for example, one or more vehicles equipped with vehicle UEs can be grouped together via a remote-driven application. Other embodiments may include scenarios where non-vehicle UEs (e.g., P-UEs) can communicate with vehicle UEs. Other use cases where multiple user equipments can be grouped together for sidelink communication with each other include, for example, factory automation and power distribution. In the case of factory automation, multiple mobile or stationary machines within a factory can be equipped with user equipment and grouped together for sidelink communication, for example, for controlling machine operation, such as robot motion control. In the case of power distribution, entities within a power distribution network can be equipped with corresponding user equipment, and within a specific area of ​​the system, the corresponding user equipment can be grouped together to communicate with each other via sidelink communication, allowing for system monitoring and handling of power distribution network faults and interruptions.

[0034] Naturally, in the use cases mentioned above, sidelink communication is not limited to communication within a packet. Rather, sidelink communication can occur between any UE (such as any pair of UEs).

[0035] As referenced above Figure 1A , Figure 1B , Figure 2 ,or Figure 3 In the described wireless communication system or network, sidelink communication between corresponding user equipment can be realized, such as vehicle-to-vehicle communication (V2V), vehicle-to-infrastructure communication (V2I), vehicle-to-pedestrian communication (V2P), vehicle-to-home communication (V2H), vehicle-to-network communication (V2N), vehicle-to-anything communication (V2X), or any other user equipment (e.g., between the devices mentioned above).

[0036] Release 14 of the 3GPP standard includes the initial vehicle-to-everything (V2X) specification. This release also includes definitions for communication between vehicles and pedestrians. Release 14 specifies the resource definitions used by pedestrian UEs (P-UEs) and the procedures for resource selection.

[0037] Although this feature is not included in NR V2X version 16, it is envisioned to be covered in version 17. With the new version and update requirements for enhanced reliability, reduced latency, and the implementation of multicast / multicast and unicast communication, there are few problems with existing implementations of P-UE. In version 14, P-UE operated essentially in the same way as a vehicle. It needed to constantly monitor a selected resource pool to receive transmissions from the vehicle. This was acceptable for vehicles because they did not have arbitrary power efficiency issues; however, this is not the case for P-UEs, which are essentially headsets or sensors with limited battery and power capabilities.

[0038] Even if the P-UE is far from the road, the resource pool that the P-UE monitors for all conversion types and modes increases the power consumption burden on the P-UE.

[0039] Furthermore, P-UE can also be an NR UE with limited processing capabilities in intermediate layer NR devices (such as MTC devices, NR lighting devices, wearable devices, etc.). As expected of NR V2X UEs, these devices include special power-saving capabilities and therefore should not monitor the entire V2X spectrum. Although P-UE stands for pedestrian UE, the described implementation is not limited to this scenario but should include usage scenarios involving the aforementioned intermediate layer devices.

[0040] In version 14, pedestrian-to-vehicle (P2X) communication or P2X procedures follow a similar guidance to normal V2X communication. The P-UE receives resource pool configuration from the gNB and is expected to select the relevant resource pool based on the area concept and its location.

[0041] Once the P-UE detects an appropriate resource pool, it operates in the same manner as a normal vehicle UE (V-UE). In LTE Mode 3 or NR V2X Mode 1, resources are requested from the gNB by sending a scheduling request and a buffer status report (BSR), whereby the gNB provides a DCI format, such as Format 5a in LTE, containing information about the time-frequency resources used by the P-UE transmission. The P-UE then sends the SCI of the location with the data resources to the relevant receiver.

[0042] like Figure 5As exemplarily illustrated, P-UE 501 can operate in various indoor scenarios 504 or outdoor scenarios 505. P-UE 501 can also listen to a receive (RX) resource pool defined for vehicle communications and, accordingly, receive transmissions from other P-UE 501s or V-UE 206s. This is independent of the location of P-UE 501; for example, it may be located indoors and completely away from any vehicle's vicinity, but still need to receive transmissions from other UEs. P-UE 501 intended for outdoor movement decodes messages sent from the RX resource pool and / or messages from other P-UE 501s or V-UE 206s. Furthermore, P-UE 501 located indoors within industrial manufacturing facilities may have special use cases where it must listen to an RX pool used nearby, which is only for private networks, such as campus networks or industrial communications, such as Industrial IoT (IIoT) networks. Here, campus network refers to a separate NR network deployed for international NR deployments, separate from commercial NR networks, such as industrial manufacturing sites or secure public infrastructure (e.g., airports, power plants).

[0043] Overview of the concept

[0044] To summarize the non-limiting embodiments of P-UE 501 and V-UE 206 mentioned above, it is conceivable that a UE can generally be configured to utilize communication services that may be permanently available or should be permanently available, such as communication with a base station, for example, using a Uu link. According to the principles of the invention, a UE can utilize another communication service that is not permanent but only conditionally available, and / or the UE can only use that other communication service if one or more predetermined conditions are met, as will now be described in detail.

[0045] In the following sections, different solutions for improving the efficiency of P-UE 501 based on its position and orientation relative to other V-UE 206 are presented only as non-limiting embodiments. P-UE 501 may be configured with an appropriate resource pool of gNB, or roadside unit (RSU), or packet leader UE (GL-UE), or another UE, but transmission and reception are only performed when in a specific location.

[0046] As mentioned above, since the present invention is not limited to P-UE 501 and / or V-UE 206, the transceiver can be described below. The transceiver may include UEs, such as P-UE, V-UE, IoT devices, or any other device capable of communicating with one or more other devices specifically via a Uu link and / or via a side link (e.g., PC5).

[0047] like Figure 6AAs shown, a first aspect of the invention relates to a transceiver 10 for wireless communication in a wireless communication network 100. Specifically, the transceiver 10 is configured to participate in at least one communication service 20 provided by the wireless communication network 100. One or more additional transceivers 21 may be participants in at least one communication service 20.

[0048] The transceiver 10 includes a communication interface 13 for receiving and / or sending communication data 14, 15 in relation to at least one communication service 20, such as vehicle communication or communication with any other transceiver 21, for example via a side link (e.g., via PC5).

[0049] As mentioned above, at least one communication service 20 may be used conditionally only by transceiver 10, and / or transceiver 10 may use at least one communication service 20 conditionally, that is, only if one or more predetermined conditions are met. Thus, arrows 14 and 15, respectively, representing the transmission and reception of communication data, are depicted in dashed lines. Therefore, transceiver 10 is configured to transmit and / or receive communication data 14 and 15 related to at least one communication service 20 only if at least one of the following predetermined criteria is met:

[0050] a. Determine that the current location of transceiver 10 is within a designated geographical area 500 related to at least one communication service 20; and / or

[0051] b. Transceiver 10 receives an information signal 16 from a second service 22 (e.g., cellular communication of base station 201), the second service 22 being different from at least one communication service 20; and / or

[0052] c. Transceiver 10 receives communication data 23 in relation to at least one communication service 20, for example, within a specific sensing window / time window.

[0053] The following sections provide a more detailed explanation of standards a) and c). Standard b) anticipates notification signal 16. For example, notification signal 16 may include a notification to transceiver 10 that at least one communication service 20 is available and that transceiver 10 should use at least one communication service 20 to send and / or receive communication data. Additionally or alternatively, notification signal 16 may include, for example, configuration data for configuring transceiver 10, and / or resource allocation information for enabling transceiver 10 to participate in at least one communication service 20.

[0054] As mentioned above, transceiver 10 can receive notification signal 16 from the second service 22. The second service 22 can be a communication service of a different type from at least one communication service 20. For example, the second service 22 can be a permanently available communication service, such as a communication service provided by base station 201 for example, communicating with base station 201 via a Uu link.

[0055] The notification signal 16 may be provided from the second service 22 to the transceiver 10. The notification signal 16 may include a display signal received by the transceiver 10, triggering the transceiver 10 to receive and / or transmit communication data 14, 15 related to at least one communication service 20, such as a display trigger, or a broadcast signal or multicast signal via the MIB / SIB. Alternatively, the notification signal 16 may include resource allocation information within configuration resources received by the transceiver 10 for explicitly configuring the transceiver 10 to receive and / or transmit communication data 20 related to at least one communication service 20.

[0056] According to standard c), transceiver 10 can be configured to receive communication data 23 in relation to at least one communication service 20. This may be related to... Figure 6A The communication data 14 and 15 depicted are different from the communication data 23. For example, communication data 23 related to at least one communication service 20 may have been sent before the transceiver 10 was able to participate in at least one communication service. Alternatively, communication data 14 and 15 may be communication data received and / or sent by the transceiver 10 after the transceiver 10 is able to participate in at least one communication service. This is one difference between communication data 23 and communication data 14 and 15. The transceiver 10 is only able to participate in at least one communication service 20 upon receiving communication data 23.

[0057] According to an embodiment, received communication data (23) in relation to at least one communication service (20) is received:

[0058] Within the scheduled time window; and / or

[0059] Within a predetermined frequency range, for example, within a bandwidth portion (BWP) or resource pool (RP); and / or

[0060] In more than one transmission instance; and / or

[0061] Within the predefined message types.

[0062] Regarding the predefined message type, as a non-limiting embodiment, it may be that the transceiver 10 only responds to other V2X messages but not other P-UE messages, or only responds to specific V2X messages, such as high-priority messages like emergency messages for sensor failures.

[0063] Definition of geographical region

[0064] The designated geographical area 500 mentioned above in relation to at least one communication service 20 may be at least one of the following:

[0065] The spatial vicinity of at least one of the one or more other transceivers 21 associated with at least one communication service 20;

[0066] The spatial area associated with at least one communication service 20;

[0067] Infrastructure related to at least one communication service 20, such as transportation infrastructure;

[0068] The vicinity of Road 502;

[0069] Near the space of 503 at the intersection;

[0070] Near the road construction site;

[0071] For example, the space near roadside equipment such as lampposts and guardrails;

[0072] Near the space where vehicle user equipment is located;

[0073] Near hazardous areas in industrial sites, such as near automated machines on factory floors;

[0074] Location within the communication range of at least one of one or more other transceivers 21 associated with at least one communication service (20);

[0075] The location of at least one of one or more additional transceivers 21 associated with at least one communication service 20 within the minimum required communication range;

[0076] For example, the space near the infrastructure equipment of the roadside unit (RSU);

[0077] For example, the location within the communication range of infrastructure equipment in a roadside unit (RSU).

[0078] Transportation infrastructure can also be dedicated infrastructure (e.g., campus networks), such as industrial manufacturing sites, or safe public infrastructure (e.g., airports, power plants, etc.).

[0079] For example, such as Figure 5 As shown, P-UE 501 can determine whether it is located within the specified geographic area 500, for example, near traffic-related scenarios, such as near roads 502, intersections 503, V-UE 206, etc.

[0080] According to an implementation, transceiver 10 (e.g., including P-UE 501) can be configured to determine whether it is located within a designated geographical area 500 by sensing (e.g., periodically or based on the motion state of transceiver 10) the presence of any communication data 23 related to at least one communication service 20. That is, if transceiver 10 can detect the communication data 23 (e.g., a V2X message), transceiver 10 can thereby infer that it is located within the designated geographical area 500 (e.g., near road 502).

[0081] The transceiver 10 can be further configured to determine whether it is located within a specified geographical area 500 by judging its location (e.g., by GNSS, cellular positioning, WiFi-assisted positioning, etc.).

[0082] For example, transceiver 10 can be configured to determine its location by using at least one of the following:

[0083] GNSS;

[0084] Cellular positioning;

[0085] WiFi-based assisted positioning;

[0086] Fingerprint printing using radio technology;

[0087] Transceiver 10 thereby obtains its location as location data or as a mechanism for determining whether transceiver 10 is located within a specified geographic area 500, based on signals emitted from network 100 or from another transceiver, such as another UE (e.g., a smartwatch that may not have built-in GPS but informs its location via an external device, such as a smartphone).

[0088] It should be mentioned that network 100 can be base station 201, another UE 21 (e.g., vehicle UE), an entity within the core network (e.g., a V2X server within the core network), or an over-the-top (OTT) of the Internet.

[0089] For example, transceiver 10 can be configured to determine whether it is located within a designated geographic area 500 by direct or indirect indications from network 100. For example, direct indications could be RRC, DCI, SIB, multicast / broadcast indicating a secure area or disabling P-UE functionality. Indirect indications could be auxiliary information from network 100 to help transceiver 10 determine whether it is located within the designated geographic area 500, such as information about secure areas around a base station (measurements such as path loss), beam information, or timing advances to allow the transceiver to determine whether it is part of the designated geographic area 500.

[0090] According to this embodiment, the transceiver 10 can be configured to determine whether it is located within a specified geographical area 500 by at least one of the following methods:

[0091] Direct or indirect instructions from the network (100);

[0092] Direct or indirect instructions from external applications residing in the transceiver (10) (e.g., pre-stored applications) or external applications not residing in the transceiver (10) (e.g., Internet applications).

[0093] The aforementioned indirect instructions from external applications could be a pre-stored layout specifying a geographic region 500, such as a geofence.

[0094] At least one embodiment of a communication service

[0095] As mentioned above, according to the embodiments, transceiver 10 may include a sidelink communication interface, wherein at least one communication service 20 may include communication between transceiver 10 and at least one of one or more other transceivers 21 associated with at least one communication service 20 via its sidelink communication interface.

[0096] According to a non-limiting embodiment, at least one communication service 20 may include communication using a device-to-device (D2D) communication protocol (e.g., a vehicle-to-everything (V2X) communication protocol that includes vehicle-to-pedestrian communication), the communication relating to communication with a pedestrian UE (P-UE). Another embodiment of device-to-device (D2D) communication is vehicle-to-infrastructure (V2I) communication.

[0097] Transceiver 10 can perform D2D communication via its communication interface 13, which may include a sidelink interface, such as a PC5 interface. For example, transceiver 10 may include a sidelink communication interface 13, such as a PC5 interface, and at least one communication service 20 may include communication between transceiver 10 and at least one or more other transceivers 21 associated with the at least one communication service 20 via its sidelink communication interface 13. Transceiver 10 may be configured to receive resource configuration including configuration information for configuring the sidelink communication interface 13.

[0098] According to an embodiment, one or more transceivers 21 associated with at least one communication service 20 may include at least one vehicle user equipment. Therefore, one or more of these transceivers 21 may be vehicle UEs associated with V2X services.

[0099] The second service 22 may include, for example, communication with one or more base stations 201 via an additional PC5 interface, and / or one or more additional transceivers (not shown) associated with the second service 22. For example, the one or more transceivers associated with the second service 22 may include at least one base station 201 and / or at least one user equipment.

[0100] The present invention may also relate to a corresponding base station 201, for example, a base station 201 for a wireless communication network 100. The base station 201 may be configured to provide at least one transceiver 10 with resource configuration and / or one or more resources related to at least one communication service 20. The resource configuration includes configuration information for configuring the communication interface of at least one transceiver 10 to participate in communication with one or more other transceivers 21 related to at least one communication service 20. At least one transceiver 10 may use the one or more resources to participate in the communication with one or more other transceivers 21.

[0101] If it is determined that the current location of at least one transceiver 10 is within or outside a designated geographical area 500 related to at least one communication service 20, then the base station 201 of the present invention may be configured to provide the resource configuration to at least one transceiver 10. Alternatively, the base station 201 may be configured to provide the one or more resources to at least one transceiver 10 only if it is determined that the current location of at least one transceiver 10 is within or near a designated geographical area 500 related to at least one communication service 20.

[0102] Base station 201 can be configured to provide resource configuration and / or one or more resources for at least one communication service 20 through a second service 22, which is different from at least one communication service 20. The second service 22 can be, for example, a communication service that enables communication between transceiver 10 and base station 201 via a Uu link.

[0103] As further described above, base station 201 can send notification signal 16 to transceiver 10 via second service 22.

[0104] Idea 1: Enabling / Disabling P-UE Communication Based on Location and / or Mobility State

[0105] In this concept, it is proposed that transceiver 10 (e.g., P-UE) may send and / or receive communications related to at least one communication service 20, such as V2X communications, only when transceiver 10 (e.g., P-UE) is located near a designated geographic area 500, such as road 502, intersection 503, and other potentially high-risk areas that are usually involved in traffic to some extent.

[0106] To enhance the power and battery utilization of P-UE 10, it is advantageous to enable P-UE 10 to send and receive V2X communications only when located near roads 502, intersections 503, and other potentially high-risk areas. To achieve this, P-UE 10 can receive resource pool configuration from gNB 201 but not send or receive within the resources, unless P-UE 10 is located near a designated geographic area 500, such as near vehicles.

[0107] UE 10 utilizes advanced positioning technology to achieve this goal, enabling V2X applications running on P-UE 10 to perceive roads 502, intersections 503, and other areas near the vehicle. Only when located in these areas does P-UE 10 request resources to transmit its location from gNB 201 to other transceivers 21 associated with at least one communication service 20 (e.g., to other V-UEs 21 and / or P-UEs 21).

[0108] According to an implementation, the transceiver 10 may include a location determination unit configured to determine the current location of the transceiver 10 and, based on the current location, determine whether the transceiver 10 is located within a designated geographical area 500 associated with at least one communication service 20. Alternatively, the transceiver 10 may include a mobility state determination unit configured to determine the current mobility state of the transceiver 10 and, based on the current mobility state, determine whether the transceiver 10 is located within the designated geographical area 500 associated with at least one communication service 20. Further, alternatively, the transceiver 10 may be configured to sense the presence of any communication data 23 associated with at least one communication service 20, and, if the communication data 23 is successfully detected, determine whether the transceiver 10 is located within the designated geographical area 500 associated with at least one communication service 20.

[0109] According to another embodiment, transceiver 10 may include a mobility state determination unit configured to determine the current mobility state of transceiver 10 and, based on the current mobility state, determine whether transceiver 10 is in a mobility state, from which transceiver 10 can infer its ability to participate in at least one communication service (20). For example, transceiver 10 can only transmit if transceiver 10 (e.g., P-UE) is currently moving or moved recently before a certain time.

[0110] According to this embodiment,

[0111] If it is determined that the current location of transceiver 10 is within a specified geographical area 500 related to at least one communication service 20; and / or

[0112] If transceiver 10 successfully receives communication data 23 related to at least one communication service 20;

[0113] The transceiver 10 can then be configured to actively request from the base station 201 resource configuration and / or one or more resources for at least one communication service 20.

[0114] In other words, only after the transmitter 10 receives the resource configuration from the base station 201 can the transmitter 10 successfully receive communication data related to at least one communication service 20, such as V2X communication data. The resource configuration contains a large set of resources called a resource pool. When the transceiver 10 receives the configuration, it can listen to the pool to check incoming transmissions. It can also request resources within the pool from the base station for its own transmission, as described in the scenario above.

[0115] In another scenario, by default, transceiver 10 can only connect to any application associated with at least one communication service 20, such as any V2X application, by activation via network 100 or gNB 201, for example, using RRC signaling (P-UE configuration: P-UE=On). Network 100 and / or gNB 201 may maintain tracking of other sensor data (e.g., accelerometer, direction, speed, etc.) that transceiver 10 may provide to network 100, including the location of transceivers 10 connected to network 100, or their mobility status relative to a given transceiver 10. P-UE mode is automatically activated once transceiver 10 approaches a potentially hazardous area 500. This will trigger transceiver 10 to request resources in the Buffer Status Report (BSR) for regular beacon transmissions, or gNB 201 to configure appropriately periodic authorization (CG) without requiring any display request from transceiver 10. If device or network 100 can detect the indoor / outdoor status of transceiver 10, it can be used to enable / disable P-UE communication by, for example, issuing signaling to transceiver 10.

[0116] According to an implementation, transceiver 10 may be configured to receive configuration messages from base station 201 and / or from network 100, the configuration messages including requested resource configurations and / or one or more requested resources for at least one communication service 20.

[0117] Wherein, when transceiver 10 is located within a designated geographical area 500, transceiver 10 can be configured to receive configuration messages, and when transceiver 10 is located within a designated geographical area 500, transceiver 10 can be configured to utilize resource configuration for at least one communication service 20 and / or one or more resources; or

[0118] Specifically, before transceiver 10 enters the designated geographical area 500, transceiver 10 can be configured to receive configuration messages, and before transceiver 10 is located within the designated geographical area 500, transceiver 10 can be configured to suppress the use of resource configuration and / or one or more resources for at least one communication service 20.

[0119] Therefore, transceiver 10 can be configured to receive resource pool (RP) configurations in the past, but when transceiver 10 enters or is located within a specified geographic area 500, it can choose to send and / or receive on these resources.

[0120] When it is determined that the current location of the at least one transceiver 10 is within or near a geographical area 500 related to at least one communication service 20, the corresponding base station 201 of the present invention can be configured to receive a resource configuration request message from the at least one transceiver 10. Furthermore, the base station 201 can be configured to provide resource configuration for at least one communication service 20 to the at least one transceiver 10 in response to the received resource configuration request message.

[0121] When at least one transceiver 10 is located within or near a designated geographical area 500, the corresponding base station 201 of the present invention can be further configured to send a resource configuration response message to at least one transceiver 10, the resource configuration response message including the requested resource configuration.

[0122] Alternatively, base station 201 may be configured to first provide the requested resource configuration, and then provide one or more dedicated resources. Thus, when it is determined that at least one transceiver 10 is located outside a designated geographical area 500, base station 201 may be configured to provide at least one transceiver 10 with the requested resource configuration for at least one communication service 20, and when at least one transceiver 10 is located within or near the designated geographical area 500, upon receiving a resource configuration request message, base station 201 may be configured to allocate dedicated resources from the resource configuration to at least one transceiver 10.

[0123] In order to send one or more dedicated resources to at least one transceiver 10, when it is determined that the current location of the at least one transceiver 10 is within or near a geographical area 500 related to at least one communication service 20, the base station 201 may be configured to receive a resource request message from the at least one transceiver 10. The resource request message includes a request for one or more dedicated resources related to at least one communication service 20.

[0124] In response, when at least one transceiver 10 is located within or near a designated geographical area 500, base station 201 may send a resource response message to at least one transceiver 10. The resource response message includes one or more requested dedicated resources for at least one communication service 20.

[0125] As mentioned above, transceiver 10 may include at least one sensor for generating sensor data relating to the current mobility state of transceiver 10. Transceiver 10 may be configured to provide the sensor data to base station 201 or network 100. If base station 201 and / or network 100 determine, based on the sensor data, that transceiver 10 is located within a designated geographical area 500 relating to at least one communication service 20, transceiver 100 may be further configured to receive requested resource configurations for at least one communication service 20 from base station 201 and / or from network 100.

[0126] Alternatively, when base station 201 and / or network 100 determine based on sensor data that transceiver 10 is located within a designated geographical area 500 related to at least one communication service 20, or when transceiver 10 successfully receives communication data related to at least one communication service 20, transceiver 10 may be configured to provide the sensor data to base station 201 or network 100, and transceiver 10 may be configured to receive one or more requested resources for at least one communication service 20 from base station 201 and / or from network 100.

[0127] According to an implementation, transceiver 10 can be configured to determine whether it is located indoors or outdoors. Only when the transceiver 10 is determined to be outdoors can it be configured to send and / or receive communication data 14, 15 related to at least one communication service 20. Alternatively, when the transceiver 10 is determined to be indoors, it can be configured to only receive, but not send, communication data 14, 15 related to at least one communication service 20.

[0128] Base station 201 can notify transceiver 10 of its indoor or outdoor status. For example, transceiver 10 can be configured to determine whether it is indoor or outdoor by receiving a notification from base station 201 or from network 100 indicating whether it is connected to an indoor or outdoor base station.

[0129] Alternatively, transceiver 10 may be configured to determine whether it is part of a predetermined geographical area, for example, a predetermined geographical area that is different from the geographical area 500 associated with at least one communication service 20. For example, the predetermined geographical area may refer to a geographical area not associated with at least one communication service 20. For example, transceiver 10 may include a base station located in a park or outdoors that is not associated with at least one communication service 20 (e.g., V2X communication service). According to this embodiment, if transceiver 10 can determine that it is part of the predetermined geographical area, transceiver 10 may only receive but not transmit communication data 14, 15 associated with at least one communication service 20, or transceiver 10 may actively suppress the reception and / or transmission of communication data 14, 15 associated with at least one communication service 20.

[0130] As mentioned above, base station 201 can be configured to keep tracking the current location of at least one transceiver 10 to determine when at least one transceiver 10 is located within or near a designated geographic area 500 related to at least one communication service 20.

[0131] As mentioned above, base station 201 can be configured to receive sensor data from at least one transceiver 10, wherein the sensor data may relate to the current mobility state of at least one transceiver 10, for example, to acceleration, speed, direction, altitude, etc. Based on the sensor data, base station 201 can be configured to determine whether and / or when at least one transceiver 10 is located within or near a designated geographical area 500 associated with at least one communication service 20.

[0132] Base station 201 may be further configured to send a notification to at least one transceiver 10, the notification indicating to at least one transceiver 10 whether it is connected to an indoor base station or an outdoor base station, in order to determine whether at least one transceiver 10 is located indoors or outdoors.

[0133] If it is determined that the current location of at least one transceiver 10 is outdoors, the base station 201 may be configured to send resource configuration and / or one or more resources for at least one communication service 20 to at least one transceiver 10 so that the transceiver 10 can send and / or receive communication data 14, 15 related to at least one communication service 20.

[0134] Alternatively, if it is determined that the current location of at least one transceiver 10 is indoors, the base station 201 may be configured to send the resource configuration and / or the one or more resources to at least one transceiver 10, such that at least one transceiver 10 is able to receive but not send communication data 14, 15 related to at least one communication service 20.

[0135] Figure 6B Some non-limiting embodiments of indoor and outdoor scenarios are illustrated. Base station 201 includes a coverage area. The coverage area may define at least a portion of a designated geographic area 500. It can be seen that street 502 extends through the coverage area of ​​base station 201. These portions of street 502 located within the coverage of base station 201 may define at least one portion of the designated geographic area 500.

[0136] Two transceivers 21 located within the coverage of base station 201 and associated with at least one communication service 20 are shown. q ,twenty one m A transceiver 21 q It can include a V-UE, and another transceiver 21 m It can include P-UE.

[0137] The transceiver 10 of the first invention p It can be located within the coverage of base station 201, but inside building 5041. Base station 10 of the second invention. k It can also be located within building 5042. Small cell 600 can provide cellular coverage within building 5042. Small cell 600 can provide a so-called campus network. The campus network can be a privately operated network, for example, capable of supporting all types of QoS or emergency calls without restricting network neutrality, i.e., mandatory use of public wireless networks. For example, a campus network, campus LAN, or enterprise LAN (CAN) can be a computer network consisting of interconnected LANs within a limited geographical area. Network equipment (switches, routers) and transmission media (fiber optic cables, copper cables, Cat5 cables, etc.) are almost entirely owned by the campus tenant / owner: for example, businesses, universities, governments, etc. A campus LAN may be larger than a LAN but smaller than a metropolitan area network (MAN) or wide area network (WAN). Optionally, in addition, the transceiver 10 of the second invention... k It can also be located within the coverage area of ​​base station 201. For example... Figure 6B As exemplarily shown, the coverage area 601 of the campus network provided by the small cell 600 may overlap with the coverage area 500 of the base station 201.

[0138] As mentioned above, network entities, such as base station / NR-U base station 201, can communicate with transceiver 10 (e.g., to P-UE 10) via messages (broadcast, MIB, SIB, RRC, multicast). p 10 k The transceiver 10 indicates that it is connected to an indoor base station. If the indoor / outdoor status cannot be directly detected, the base station 201 can define a "safe zone" 602 based on, for example, path loss / received strength, i.e., if the transceiver 10 pIf a path loss (PL) > x dBm, it can be considered to be within the "safe zone" 602 and thus too far from the base station 201. Therefore, transceiver 10 p It is "secure" and therefore does not require sending / receiving communication data 14, 15 related to at least one communication service 20, such as SL messages. On the other hand, if the path loss is below a threshold, the transceiver 10 is outside the "secure zone" (see, for example, P-UE 21). m And it must be used as a P-UE or other sensor data must be used to detect whether it must be used as a P-UE. Furthermore, the P-UE can be located in the configuration of the P-UE 10. k The aforementioned campus network (indoor or outdoor) coverage area is used to decode the appropriate RP and / or V-UE messages accordingly.

[0139] Therefore, according to the exemplary embodiment, transceiver 10 can be located inside or outside the "safe zone" 602. For example, if transceiver 10 has a path loss higher than a predetermined threshold, transceiver 10 can be configured to determine whether it is located within the "safe zone" 602. Then, transceiver 10 can be configured to actively suppress receiving and / or transmitting communication data 14, 15 related to at least one communication service 20.

[0140] Alternatively, if transceiver 10 has a path loss below a predetermined threshold, transceiver 10 may be configured to determine that it is outside the “safe zone” 602. Then, transceiver 10 may be configured to send and / or receive communication data 14, 15 related to at least one communication service 20.

[0141] Another implementation may involve the campus network mentioned above. According to this implementation, when it is determined that the current location of transceiver 10 is indoors, if transceiver 10 is within the coverage of a separate campus network, for example, if at least one communication service 20 is related to services primarily provided outdoors (e.g., vehicle (V2X) services, etc.), then transceiver 10 can be configured not to receive and / or transmit communication data related to at least one communication service 20. For example, transceiver 10 may include a P-UE that, when indoors, does not need to transmit and / or receive V2X data.

[0142] Alternatively, even if the current location of transceiver 10 is determined to be indoors, for example, if at least one communication service 20 may be related to services primarily provided outdoors (e.g., robots, etc.), transceiver 10 may also be configured to receive and / or transmit communication data related to at least one communication service 20.

[0143] Furthermore, the corresponding base station 201 of the present invention can be configured to determine whether at least one transceiver 10 is located inside or outside the aforementioned “safe zone” 602 by, for example, the path loss threshold mentioned above.

[0144] For example, if base station 201 determines that at least one transceiver 10 has a path loss higher than a predetermined threshold, base station 201 may be configured to send resource configuration and / or one or more resources for at least one communication service 20 to at least one transceiver 10 so that at least one transceiver 10 can actively suppress receiving and / or sending communication data 14, 15 related to at least one communication service 20.

[0145] If base station 201 alternatively determines that at least one transceiver 10 has a path loss below a predetermined threshold, then base station 201 is configured to send the resource configuration and / or the one or more resources to at least one transceiver 10 so that at least one transceiver 10 can send and / or receive communication data 14, 15 in relation to at least one communication service 20.

[0146] Idea 2: Once the P-UE approaches the vehicle, the gNB proactively provides resources for transmission.

[0147] In this idea, it is proposed that because gNB 201 can sense the location of transceiver 10 (e.g., P-UE), rather than the resources requested by transceiver 10 for transmission (which essentially refers to the location of all other transceivers 21 (e.g., V-UE) nearby (“I am here” message)), gNB 201 can proactively provide resources for the transmission.

[0148] As mentioned in the previous section, transceiver 10, such as P-UE, can only request resources for broadcasting, multicasting, or unicasting its location when it is located near a designated geographic area 500, for example, when it is near a vehicle. However, gNB 201 can be more efficient if it can also be aware of the presence of transceiver 10 within these designated geographic areas 500 (e.g., near a vehicle). Because transceiver 10 can periodically transmit its location to gNB 201, gNB 201 can proactively send resources to transceiver 10 for transmitting its location. Of course, it is preferable if gNB 201 is aware of the designated geographic area 500, such as the area near a vehicle.

[0149] In another embodiment, transceiver 10 may also be configured to report only whether a specific condition has been triggered. The condition may refer to the last reported physical distance, a change in mobility status, a change in orientation (motion vector), a change in indoor / outdoor status, or any combination thereof in conjunction with timer functionality in the listed embodiments. This can be configured by base station 201, network 100, or another UE 21 (e.g., a GL-UE).

[0150] According to an implementation, transceiver 10 can be configured to periodically send information about its current location to base station 201. If the information about its current location indicates to base station 201 that transceiver 10 is located within a designated geographical area 500 related to at least one communication service 20, transceiver 10 can be configured to actively receive resource configuration related to at least one communication service 20 from base station 201 without first sending a resource configuration request message to base station 201.

[0151] Alternatively, transceiver 10 may have previously received resource configurations related to at least one communication service 20, and then transceiver 10 may request one or more dedicated resources from the resource configurations.

[0152] According to this embodiment, transceiver 10 can be configured to periodically send information about its current location to base station 201. If the information about its current location indicates to base station 201 that transceiver 10 is located within a designated geographical area 500 related to at least one communication service 20, and if transceiver 10 has previously received resource configuration related to at least one communication service 20, transceiver 10 can receive one or more resources for at least one communication service 20 actively offered by base station 201 without having previously sent a resource request message to base station 201.

[0153] The transceiver 10 can be configured to transmit information about its current location at least once or periodically in response to a predetermined condition being met, wherein the predetermined condition includes at least one of the following:

[0154] The spatial distance to the previous position, at which transceiver 10 previously sent information about its current position to base station 201;

[0155] Changes in the mobility state of transceiver 10;

[0156] Changes in the direction of movement of transceiver 10;

[0157] The change between indoor and outdoor conditions; or

[0158] A combination of one or more of the above-mentioned functions that incorporate timer functionality.

[0159] For example, changes in the direction of movement of transceiver 10 can be detected by motion vector detection. For example, the acceleration and / or deceleration of transceiver 10 can be determined. For example, if transceiver 10 slows down (decelerates), transceiver 10 can be configured to suppress the reception and / or transmission of communication data 14, 15 related to at least one communication service 20.

[0160] The corresponding base station 201 of the present invention can proactively provide transceiver 10 with resource configurations and / or one or more dedicated resources related to at least one communication service 20. Therefore, the base station 201 of the present invention can be configured to periodically receive information about the current location of at least one transceiver. If the information about its current location indicates to the base station 201 that at least one transceiver 10 is located within a geographical area 500 related to at least one communication service 20, then the base station 201 can be configured to proactively provide resource configurations for at least one communication service 20 to at least one transceiver 10 without having previously received a display resource configuration request message from at least one transceiver 10.

[0161] Alternatively, if at least one transceiver 10 has previously received resource configuration for at least one communication service from the base station 201, the base station 201 may be configured to proactively offer one or more resources for at least one communication resource 20 to at least one transceiver 10 without having previously received a display resource request message from at least one transceiver 10.

[0162] Idea 3: Once the P-UE approaches the vehicle, the RSU proactively relays the resources used for transmission.

[0163] Similar to previous concepts, a relay unit, such as a roadside unit (RSU) or other relay UE, is proposed that can provide resource configuration and / or one or more resources to transceiver 10 to transmit its location to other UEs 21, such as V-UEs.

[0164] This is similar to idea 1 above, except that the relay unit can be located within a designated geographical area 500. For example, the RSU can be located in the area near the vehicle, and therefore, no additional information is required other than the transceiver 10 requesting resource configuration and / or one or more resources. The relay unit has been configured to relay resource configuration and / or one or more resources via gNB 201. For example, the RSU has been configured to relay resources for the P-UE via gNB 201.

[0165] According to this embodiment, when the transceiver 10 is located within a designated geographical area 500 related to at least one communication service 20, the transceiver 10 can be configured to send a resource configuration request message to the base station 201 to request resource configuration related to at least one communication service 20. According to this embodiment, the transceiver 10 can be configured to send the resource configuration request message to the base station 201 via a relay unit (e.g., RSU) that relays the resource configuration request message to the base station 201.

[0166] Alternatively, when transceiver 10 is located within a designated geographical area 500 associated with at least one communication service 20, transceiver 10 may be configured to receive a requested resource configuration associated with at least one communication service 20 from base station 201 via a relay unit (e.g., RSU) that relays the resource configuration from base station 201 to transceiver 10.

[0167] There are two possible scenarios. In the first scenario, the transceiver first requires the resource configuration described above, for example, via a relay unit. In the second scenario, transceiver 10 has already received the resource configuration, but now needs to request one or more dedicated resources as described below.

[0168] If transceiver 10 has previously received resource configuration, transceiver 10 may request one or more dedicated resources for at least one communication service 20.

[0169] According to this embodiment, when transceiver 10 is located within a designated geographical area 500 related to at least one communication service 20, and when transceiver 10 has previously received resource configuration related to at least one communication service 20, transceiver 10 can be configured to send a resource request message to base station 201 to request one or more resources for at least one communication service 20 from base station 201. According to this embodiment, transceiver 10 can be configured to send the resource request message to base station 201 via a relay unit that relays the resource request message to base station 201.

[0170] Alternatively, when transceiver 10 is located within a designated geographical area 500 associated with at least one communication service 20, and when transceiver 10 has previously received resource configurations associated with at least one communication service 20, transceiver 10 may be configured to receive one or more requested resources for at least one communication service 20 from base station 201 via a relay unit that relays the one or more resources for at least one communication service 20 from base station 201 to transceiver (10).

[0171] The relay unit may be located within a designated geographical area 500 relating to at least one communication service 20. The relay unit may include at least one of the following:

[0172] Roadside unit;

[0173] Vehicle user equipment; or

[0174] Airplanes, helicopters, unmanned aerial vehicles (e.g., drones), and satellites (NTN).

[0175] Additional transceiver 21 associated with at least one communication service 20;

[0176] Additional transceiver 21 related to the second service 22.

[0177] The corresponding base station 201 of the present invention can provide resource configuration and / or one or more dedicated resources for at least one communication service 20 to the transceiver 10 by means of relay unit relay.

[0178] In order to provide resource configuration via a relay unit, when at least one transceiver 10 is located within a geographical area 500 relating to at least one communication service 20, the base station 201 of the present invention can be configured to receive a resource configuration request message from at least one transceiver 10 to request resource configuration. The base station 201 can receive the resource configuration request message from at least one transceiver 10 via a relay unit that relays the resource configuration request message to the base station 201.

[0179] In response, when at least one transceiver 10 is located within a geographical area 500 relating to at least one communication service 20, base station 201 may be configured to send the requested resource configuration to at least one transceiver 10 via a relay unit or another relay unit.

[0180] To provide one or more dedicated resources via a relay unit, when at least one transceiver 10 is located within a geographical area 500 relating to at least one communication service 20, the base station 201 of the present invention can be configured to receive a resource request message from at least one transceiver 10 to request one or more resources for at least one communication service 20. The base station 201 can be configured to receive the resource request message from at least one transceiver 10 via a relay unit that relays the resource request message to the base station 201.

[0181] In response, when at least one transceiver 10 is located within a geographical area 500 relating to at least one communication service 20, base station 201 may be configured to send one or more requested resources for at least one communication service 20 to at least one transceiver 10 via a relay unit or another intermediate unit.

[0182] Idea 4: Resources delivered via the new DCI / SCI format

[0183] As described above, gNB 201 can use the new DCI format to provide time-frequency resources for the location of broadcast transceiver 10.

[0184] As described above, a relay unit (e.g., an RSU or a dedicated relay UE) can use the new SCI format to provide time and frequency resources for transceiver 10 (e.g., a P-UE).

[0185] To facilitate the above ideas, gNB 201 can adopt a new DCI format to proactively provide resources to transceiver 10 (e.g., P-UE). Relay units (e.g., RSUs) can also provide the same resources, but in SCI format.

[0186] The content of DCI / SCI can be as follows:

[0187] Transmission time-frequency location

[0188] Periodicity and duration of transmission

[0189] One focus of this idea might be defining new DCI and new SCI to cater to the needs of pedestrian UE 10 with this capability. P-UE 10 can essentially be a normal UE (earphone), and the current set of DCIs sent / received to these UEs by base station 201 does not include information about SL communication. Similarly, SCI can currently only be sent / received by V-UE, not normal UE 10.

[0190] According to an embodiment, transceiver 10 can be configured to read all SIBs required by a normal UE, as well as SIBs related to sidelinks. This enables transceiver 10 to obtain configuration information about the RP and, consequently, to send / receive DCIs related to sidelink communications. Transceiver 10 can only choose to read the SL SIB if it is informed that it is within a specified geographical area 500.

[0191] Therefore, according to the implementation, transceiver 10 can be configured to receive system information (SIB) related to at least one communication service 20 from base station 201. The system information related to at least one communication service 20 enables transceiver 10 to receive resource configuration and / or one or more resources related to at least one communication service 20, and to receive and / or transmit control information (DCI re. SL communication) related to at least one communication service 20.

[0192] According to another embodiment, transceiver 10 can be configured to read system information (SIB) related to at least one communication service 20 only if transceiver 10 is located within a designated geographical area 500 associated with at least one communication service 20.

[0193] The corresponding base station 201 of the present invention can be configured to transmit system information (SIB) related to at least one communication service 20 (and optionally system information (SIB) related to a second service 22) to at least one transceiver 10, wherein the system information related to at least one communication service 20 enables the transceiver 10 to receive resource configuration and / or one or more resources for at least one communication service 20, and to receive and / or transmit control information (DCI re. SL communication) related to at least one communication service 20.

[0194] Idea 5 - Resources provided via RRC signaling

[0195] Resources for beacon transmission can be provided using configuration grants (CGs) within the V2X pool. However, transceiver 10 may not need to be aware of the existence of the V2X pool. The V2X pool may appear to be a common UL spectrum / timeslot / pool for transceiver 10, where it is instructed to transmit its beacon via gNB 201. However, beacon transmission itself differs from common PUSCH transmission in some sense as follows:

[0196] Different transmission structures (PSCCH+PSSCH)

[0197] Different DMRS configurations

[0198] Different SCS

[0199] Not equipped with UCI

[0200] Other UEs 21, such as V2X UEs, can replace the presence of the sensing pool and can decode beacon information to enable their sensing transceivers 10.

[0201] Another implementation involves providing periodic resources within a resource configuration (e.g., within a P-UE configuration) such that these periodic resources can be bound to beacon transmissions and other transmissions are not permitted. Furthermore, different configuration parameters may also be transmitted within said configuration.

[0202] Another option is to configure a normal CG, but associate the CG configuration with beacon transport / P-UE behavior. This can be done by providing the CG configuration ID within the resource configuration (e.g., within the P-UE configuration) (optionally, along with the associated transport parameters), and may produce the behavior described in the previous paragraphs.

[0203] Therefore, according to an implementation, when the transceiver 10 is located within a designated geographical area 500 associated with at least one communication service 20, the transceiver 10 can be configured to receive configuration messages, such as Radio Resource Control (RRC) messages, from the base station 201. Alternatively, the transceiver 10 can be configured to receive configuration messages before entering the designated geographical area 500 associated with at least one communication service 20. In any case, the transceiver 10 can be configured to configure its communication interface for communication related to at least one communication service 20 in response to the configuration messages.

[0204] When at least one transceiver 10 is located within a geographical area 500 associated with at least one communication service 20, the corresponding base station 201 of the present invention can be configured to send configuration messages (e.g., Radio Resource Control (RRC) messages) to at least one transceiver 10. The configuration messages may include resource configuration and / or one or more resources for at least one communication service (20).

[0205] According to an embodiment, the configuration message may include one or more periodic resources, such as one or more periodically reconfigured authorization CGs, wherein the transceiver 10 may be configured to use one or more periodic resources to periodically send communication data 14, 15 related to at least one communication service 20, such as one or more beacons.

[0206] One or more periodic resources may be exclusively reserved for the periodic transmission of communication data 14, 15 in relation to at least one communication service 20, that is, periodic resources may be bound to beacon transmissions and other transmissions may not be permitted.

[0207] At least one of the periodic resources included in the configuration message may include an identifier, such as a CG configuration ID, which identifies the particular periodic resource as a resource for the periodic transmission of communication data 14, 15 in relation to at least one communication service 20 (e.g., for beacon transmission). That is, the CG configuration ID can be used to associate a CG configuration with beacon transmission.

[0208] According to this embodiment, transceiver 10 can be configured to identify the specific periodic resource based on an identifier and use the specific periodic resource for periodic transmission of communication data 14, 15 in relation to at least one communication service 20.

[0209] Idea 6 - Sensing triggered P-UE transmission

[0210] Transceiver 10 can periodically sense the spectrum associated with at least one communication service 20, and can begin transmitting when other communication data 23 associated with at least one communication service 20 is detected. For example, P-UE 10 can periodically sense V2X spectrum, and can begin transmitting when other V2X transmissions are detected. In Mode 2 (M2), there may be no assistance from network 100. To determine whether transceiver 10 (e.g., P-UE) should transmit, it can periodically sense a dedicated spectrum (e.g., V2X spectrum) associated with at least one communication service 20. When other transmissions (e.g., vehicle V2X transmissions) are detected, it can begin transmitting itself or can send beacons to other UEs 21 or GL-UEs (if available) within a specific communication range to verify their participation in all communications associated with at least one communication service 20, such as all communications associated with P-UE. Periodic sensing may vary and depend on the known proximity of geographic area 500 (e.g., road, street canyon, street type - highway / expressway / urban restrictions, etc.) or the estimated or measured movement or mobility of the transceiver 10.

[0211] According to this embodiment, transceiver 10 can be configured to periodically sense a predetermined spectrum for the presence of at least one dedicated message, including data types related to at least one communication service 20. If transceiver 10 can identify at least one of the dedicated messages in the predetermined spectrum, transceiver 10 can be configured to transmit communication data 14, 15 related to at least one communication service 20.

[0212] According to another embodiment, transceiver 10 can be configured to adapt to periodically sensing the periodicity of a predetermined spectrum based on proximity to a designated geographic area 500 associated with at least one communication service 20. For example, the periodicity may increase with increasing proximity. Imagine getting closer and closer to the geographic area 500 associated with the V2X service (e.g., intersection 503). Figure 5 The closer P-UE 10 is to the intersection 503, the more frequently P-UE 10 senses the predetermined V2X spectrum for the presence of dedicated V2X messages.

[0213] Alternatively, transceiver 10 may be configured to adapt to periodically sensing the periodicity of a predetermined spectrum based on the mobility state and / or battery state of transceiver 10. For example, a P-UE 10 moving around a V2X-related geographic area 500 may sense the predetermined V2X spectrum for the presence of dedicated V2X messages more frequently, while a stationary P-UE 10 (e.g., located in front of a red traffic light) may sense the predetermined V2X spectrum for the presence of dedicated V2X messages less frequently.

[0214] Idea 7: Reduce P-UE sensing in Mode 2

[0215] Specifically, if transceiver 10 includes a P-UE, then continuous sensing and resource reselection are energy-intensive and should be minimized in the transceiver 10 of this invention. To conserve battery power, the P-UE 10 may suppress the use of normal V2X M2 sensing procedures.

[0216] Alternatively, it could be:

[0217] Random frequency hopping sensing;

[0218] For example, sensing can be performed once in a pre-configured or randomly selected frequency band, and then the selected frequency band and transmission mode can be maintained for a longer, predefined time period before switching back to the sensing procedure. This type of sensing can be configured (pre-configured) in an SPS-type style, providing the sensing duration and interval, as well as the resource selection duration and interval. Furthermore, appropriate signaling (e.g., RRC signaling) should be used to allow for reconfiguration of sensing and reselection of resource modes, durations, and intervals.

[0219] According to this embodiment, the transceiver 10 can be configured to periodically sense the predetermined spectrum between two or more frequency bands of the predetermined spectrum in a random frequency hopping mode.

[0220] Alternatively, transceiver 10 may be configured to periodically sense the presence of at least one message relating to at least one communication service 20 located in a particular selected frequency band of a predetermined spectrum within a predetermined and / or adjustable sensing duration or sensing interval.

[0221] For example, transceiver 10 can be configured to receive control messages from base station 201, such as radio resource control (RRC) messages, which include information for causing transceiver 10 to adjust at least one of the following:

[0222] Sensing duration;

[0223] Sensing interval;

[0224] Resource selection duration;

[0225] Resource selection interval.

[0226] According to a non-limiting embodiment, the transceiver 10 described herein may include at least one of the following:

[0227] Dedicated pedestrian user equipment;

[0228] Industrial mobile machines;

[0229] Unmanned aerial vehicles (UAVs) or aircraft;

[0230] Baby stroller;

[0231] Bicycles, scooters, motorcycles;

[0232] Roadside equipment, such as building signs or signage on the street.

In this state, the transceiver's ability to receive and / or send communication data 14, 15 related to at least one communication service 20 can be disabled.

[0236] Block diagram 702 illustrates that the state of transceiver 10 can be conditionally set, for example, if one or more conditions are met. This state can also be referred to as a conditional state. In this state, at least temporarily, the transceiver's ability to receive and / or send communication data 14, 15 in relation to at least one communication service 20 can be enabled.

[0237] The transceiver 10 can only be set to condition state 702 if at least one of the following predetermined criteria is met:

[0238] a. Determine that the current location of transceiver 10 is within a designated geographical area 500 related to at least one communication service 20; and / or

[0239] b. Receive a notification signal (16) from a second service 22 that is different from at least one communication service 20; and / or

[0240] c. Receive communication data 23 in connection with at least one communication service 20.
