Description

Technical Field

[0001] Embodiments of the invention relate to a method for managing, e.g. sharing, resources, and to a corresponding communication system. Another embodiment relates to a first mobile transceiver belonging to the communication system, wherein the first mobile transceiver is configured to offer a portion of its resources to be shared / offered / permitted. Another embodiment relates to a second mobile transceiver belonging to the communication system, wherein the second mobile transceiver is configured to request resources. Another embodiment relates to a user device or a vehicle comprising one of the mobile transceivers. Background Art

[0002] A mobile communication system typically includes a transceiver, such as a base station's transceiver, and multiple mobile transceivers, such as a UE or a vehicle's transceiver. Different mobile transceivers typically require different amounts of resources at different points in time. According to commonly used communication systems, there are two broad resource allocation modes:

[0003] - Centralized resource allocation - controlled by the base station - known as Mode 3 in LTE;

[0004] - Distributed resource allocation - Here, resources are allocated by any user equipment V2X service - This mode is called Mode 4 in LTE.

[0005] Both resource allocation modes cannot take into account the current demand for resources of different mobile transceivers. Therefore, an improved method capable of reallocating resources is needed. Summary of the invention

[0006] The object of the present invention is to provide a concept that enables resource management like resource reallocation, especially for V2X resource allocation networks.

[0007] This problem is solved by the subject matter of the independent claims.

[0008] One embodiment provides a method for managing / sharing resources within a communication network. The communication network includes a transceiver (e.g., a base station), a first mobile transceiver (e.g., a mobile device or a vehicle), and a second mobile transceiver (e.g., another device or another vehicle), or only two mobile transceivers (e.g., in the case of pre-configured resources). The transceivers can be configured to exchange data and / or control information with the first mobile transceiver using a first resource (e.g., a selected resource or a resource allocated to the first mobile transceiver), and to exchange data and / or control information with the second mobile transceiver. The second mobile transceiver uses a second resource, such as a selected resource or a resource allocated to the second mobile transceiver. Here, resource allocation can be performed, for example, according to one of the above-mentioned resource allocation modes (centralized or autonomous / distributed). The first mobile transceiver (also referred to as a donor) has an unused / idle / unneeded portion of the first resource that can be shared, provided or licensed, where the second mobile transceiver (also referred to as a recipient) needs more resources. The method for sharing resources comprises two basic steps, namely exchanging resource control information between a first and a second mobile transceiver, for example directly granting or providing said part (or the whole resource) of the first resource to the second transceiver in response to exchanging resource control information. Alternatively, the method may be performed as follows: exchanging resource control information between a first and a second mobile transceiver so as to provide said part of the first resource to the second transceiver so that the second transceiver can directly use the corresponding part (or the whole resource). Thus, providing means providing information so as to be able to directly use the provided resource. Note that the resource to be shared, granted or provided may be a preconfigured resource that is (selected / allocated and) not used or (selected / allocated and) used or an unallocated but idle resource.

[0009] As described above, the resource management / sharing method may have two variants: According to a first embodiment, the exchange of resource control information is initiated by the first mobile transceiver, for example using a resource offer message, so that the second mobile transceiver can react to use the offered resources. According to a second embodiment, the exchange of resource control information is initiated by the second mobile transceiver, for example using a request, so that the first mobile transceiver can grant a corresponding portion of its resources if it has available (unused) resources.

[0010] Embodiments of the present invention are based on the principle that two mobile transceivers with resources (e.g. allocated in the above pattern) can share their resources when a user whose resources are not fully consumed lends some of their resources to other users with greater needs and scarce resources. Therefore, the idea is to grant unused resources of one entity (donor) to a resource requesting entity (recipient) by notifying the recipient of its idle resources. In one embodiment, sidelink control information (SCI) can be used. According to another embodiment, the donor user can announce its unused resources on a broadcast message. The recipient user can announce the capture of donated resources on a dedicated shared channel. This basic idea enables the reallocation or reassignment of resources of one user to another user, so that both user needs can be better met compared to the initial resource allocation. The main advantage is that other UEs sharing resources on the resource pool can be notified in a very short time to keep the resources (in notification) clear. In addition, since other UEs are prevented from using the indicated resources, any high priority / urgent messages can be sent permission-free (very low latency) with high reliability.

[0011] According to one embodiment, the announcement of resource blocks can be performed in frequency or time so that the recipient can use the frequency band or time frame (subframe block) of the unused resources of the licensed donor, for example, if the donor announced the resources, no further communication is required. For example, the announced resources can be on dedicated resources, pre-configured resources and / or exceptional dedicated pools. The use of pre-configured (license-free) resources facilitates better utilization and efficient sharing.

[0012] As described above, there are two substantially different embodiments, namely, one embodiment in which the first mobile transceiver initiates the exchange of resource control information using a resource offer message, and a second embodiment in which the second mobile transceiver initiates the exchange of resource control information using a resource request message.

[0013] In a first embodiment, according to an embodiment, the method may be performed as follows. Exchanging resource control information comprises a sub-step of providing the portion to the second mobile transceiver. Here, broadcasting or sending a resource offer message is used. Furthermore, the method may optionally further comprise a sub-step, according to which the second mobile transceiver uses the offered portion. According to an embodiment, the resource offer message comprises information about the resource to be shared (granted / offered), such as time and / or frequency information, which is broadcasted to enable the recipient to directly use the portion. The message is ultimately sent on the next pre-configured (unnecessary) grant on the shared resource.

[0014] Starting from the second embodiment, according to the first embodiment, the resources are provided by the first mobile transceiver, and according to the embodiment, the method can be performed as follows: the step of exchanging resource control information includes a sub-step of requesting resources, wherein the corresponding resource request message is sent or broadcast by the second mobile transceiver. Here, the method can optionally / additionally include a step of performing the permission by the first mobile transceiver by sending a resource permission message. Advantageously, sharing without sensing will reduce complexity. The same algorithm can be used for coexistence in autonomous mode to reduce interference. The common point of the two implementations of this second embodiment is that the permission / use is performed based on guiding the prior knowledge from the recipient user to the donor user showing the sharing intention. For example, the prior knowledge is exchanged between the mobile transceiver / user equipment / vehicle via the sidelink control information (SCI) of the shared dedicated sharing request and the dedicated sharing response. Here, it should be noted that the messages can be exchanged using unicast, multicast or broadcast.

[0015] With regard to the granting, it should be noted that, according to an embodiment, the method further comprises the step of notifying the transceiver of the announced resource blocks (frequency or time, frame or subframe) corresponding to the granted portion to be shared with the second mobile transceiver. According to an embodiment, this information may be sent to the transceiver via a control channel, a data message or a combination of both. According to an embodiment, in response, the transceiver may control resource allocation or provide resources according to the announced resource blocks. In other words, the steps may be summarized, namely, the resources to be shared are announced in a control and / or data message, thereby allowing all recipients (more demanding "recipient" users) to access the allowed resources, and therefore, the base station will re-report information about the autonomous mode, activities and granting mechanisms between users (generally reporting sharing activities to the eNB / gNB). According to an embodiment, in response to the report, the eNB / gNB may provide sharing restrictions for the mobile transceiver.

[0016] According to an embodiment, the communication system may include a third mobile transceiver, such as a third mobile transceiver that needs more resources or has resources to be shared / permitted / provided. For example, in the case of two donors, the method may include the following steps: performing an iterative request for resources by the second mobile transceiver, and permitting another portion of the third resource from the third mobile transceiver. Here, the permission is performed by the third mobile transceiver itself. Starting from the two recipient users, the donor user (first mobile transceiver) can perform priority division. The step of priority division can be based on QoS level information or RSSI information of the second and third mobile transceivers. For example, for a mobile transceiver with a lower priority, the permission is denied. According to an embodiment, the priority division between the two recipient users can be performed as follows. If the RSSI value of the first mobile transceiver is lower than the RSSI value of the request of the second mobile transceiver, the first mobile transceiver accepts the request from the first mobile transceiver. If both recipient mobile transceivers have the same priority or a lower priority, the resources can be granted to both to achieve coexistence. The whole method improves reliability based on the priority selection of the donor user and the recipient user in need. In other words, the prioritization can be described as selecting permitted resources and resource sharing algorithms, and matching user patterns and QoS. According to an embodiment, if the first mobile transceiver and the second mobile transceiver have different QoS levels, or if the second mobile transceiver has a higher QoS level than the first mobile transceiver, the first mobile transceiver permits resources. This allows the donor user to prioritize his own transmission compared to the recipient user in need. In order to achieve this prioritization, the step of exchanging resource control information can include exchanging information about QoS level information or RSSI information according to an embodiment.

[0017] According to another embodiment, the power level can be used to ensure that only mobile transceivers that are at an appropriate distance from each other (the distance defined by the power level) share their resources. This helps to keep the signal-to-noise ratio at a relatively low level. This can be achieved, for example, when the radio frequency used to exchange resource control information has a controlled power (e.g., to enable resource sharing from mobile transceivers that are appropriately close, and to disable resource sharing from mobile transceivers that are very close or very far away). Here, according to an embodiment, the first mobile transceiver can analyze the power level of the request (e.g., resource request message) in parallel with the request.

[0018] According to an embodiment, the power of the recipient can be limited, which allows the first mobile transceiver (donor) to use the licensed portion itself when the first mobile transceiver (donor) increases the transmission power level to a level higher than the transmission parallelism level of the recipient mobile transceiver. Another option for reclaiming the already licensed resources is to use a switching mechanism. This switching mechanism allows Layer 1 (e.g., SCI) signaling to activate and deactivate sharing on one or more transmission occasions. Therefore, according to an embodiment, the licensed resources or the license frame of the licensed resources include a switching subframe that can activate or deactivate resource sharing. Due to this mechanism, resource sharing can be activated and deactivated during normal operation without timeout. According to another embodiment, the power of the request token and the power of the license token can be applicable to the discovered UE. Another embodiment discusses a general power scheme (interleaved power steps) for selecting transmission power. Power can also be a function of QoS.

[0019] According to the above method of embodiment 2 (sharing is initiated by the requester), the recipient user sends a request to multiple UEs in the vicinity. If the message cannot be decoded by the donor, the request will be ignored. This ensures that only users at an appropriate distance can start resource sharing. In order to avoid that there is no donor transceiver nearby that can grant resources, according to an embodiment, the recipient mobile transceiver can sense the power level and analyze the traffic between the transceiver and the first transceiver.

[0020] The above method has been described from a system perspective. Since it is clear for most of the method steps which entity performs this operation, the above given definition of the feature also relates to a method that is performed during resource sharing by one entity (e.g., by a donor or recipient UE). An embodiment provides a method for providing resources (donor) within the communication system in question. The method includes a step of exchanging resource control information, including a sub-step of providing the portion to a second mobile transceiver. Here, the provision is performed by a first mobile transceiver, for example, by unicasting and / or multicasting and / or broadcasting a resource provision message so that the second mobile transceiver can use the provided portion. Additionally or optionally, the first mobile transceiver can use a resource grant message to perform the grant, i.e., grant or provide the portion, so that the second mobile transceiver can use the provided portion. Vice versa, another embodiment provides a method for using / requesting resources (recipient) within the communication system in question. The method includes exchanging resource control information, including a sub-step of requesting resources. This step is performed by the second mobile transceiver by unicasting and / or multicasting and / or broadcasting a resource request message so that the first mobile transceiver can grant the portion to the second mobile transceiver. Here, additionally or optionally, the second mobile transceiver can use the provided granted portion as an additional step. Alternatively, the method can only include the following steps: receiving exchange resource control information including the provision of the first mobile transceiver, and using the provided portion / resources.

[0021] If the mobile transceiver or at least the first or second mobile transceiver is not within the coverage of the base station, the principles defined above can be used. In this case, pre-configured resources can be shared. Therefore, an embodiment relates to a method for managing / sharing pre-configured resources, and to a corresponding transceiver and a resulting system, which are able to manage / share resources according to the above principles. Vice versa, the first UE does not necessarily share resources from the transceiver. As a result, according to an embodiment, the first resource or the portion is a resource provided by a transceiver or a base station, or according to other embodiments, is a pre-configured resource or a pre-configured resource mapped to a geographical area or pattern. Note that the recipient UE can use the pre-configured resources to exchange resource management control information.

[0022] Another embodiment provides a method for managing resources within a communication system. The method has the following basic steps: Resource control is exchanged between a first and a second mobile transceiver using a handover subframe or a handover control frame to manage resources.

[0023] A computer program may be used to perform all the methods or steps of the methods discussed above. Therefore, another embodiment provides a computer program having a program code for performing one of the above methods or at least one of the above method steps on a computer.

[0024] Another embodiment provides a first transceiver configured to exchange resource control information (parts of which are provided by using unicast and / or multicast and / or broadcast resource provision messages). Here, the first mobile transceiver may also be configured to grant the provided part.

[0025] Another embodiment provides a second mobile transceiver configured to exchange resource control information by requesting resources or receiving exchange resource control information including providing resources. Here, the second mobile transceiver can be configured to use the provided or requested portion with or without permission.

[0026] Please note that both UEs, whether recipient or donor, can operate using distributed MAC resource allocation, i.e., as in Mode 3 LTE or Mode 4 (such as NR operation), or both UEs can operate using centralized MAC mechanism, i.e., as in Mode 3 LTE or Mode 4, such as NR operation.

[0027] Another embodiment provides a communication system including three physical transceivers, a first mobile transceiver and a second mobile transceiver. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Below, the embodiment of the present invention will be discussed with reference to the accompanying drawings. Here, the same reference numerals are given to objects having similar or identical functions, so that their descriptions can be mutually applicable and interchangeable.

[0038] Figure 1a A first mobile communication system 10 is shown having a transceiver 12, a first mobile transceiver 14 (also referred to as a UE-D or donor), and a second mobile transceiver 16 (also referred to as a UE-T or recipient). Both mobile transceivers 14 and 16 can actively communicate with a base station to exchange data and / or control information. The communication links are marked by reference numerals 14R and 16R. To enable communications 14R and 16R, a first resource 14R is allocated to the first mobile transceiver 14, while a second resource 16R is allocated to the second mobile transceiver 16. Note that the first resource and the second resource can be resources used for communication between the base station 12 and the corresponding UE / transceivers 14 and 16. Alternatively, the first resource and the second resource can be used to enable direct communication between the UEs 14 and 16 (e.g., preconfigured resources or, in general, side link resources).

[0039] It should be noted that the communication system 10 can be a cellular communication system that enables data exchange between the base station 12 and the V2X / D2D side link users. Here, a centralized resource allocation mode (similar to mode 3) and a distributed resource allocation mode (similar to mode 4) for V2X and D2X users can be implemented so that V2X and D2X can use the side link (in both directions). These modes are called "mode 1" and "mode 2" in the D2D side link. Note that preconfigured resources can be shared between users of the same mode with different QoS constraints. In the current 3GPP specifications, resource pool sharing with sensing and reporting mechanisms is proposed. Sensing itself consumes a full time of 1000ms, which will result in a longer waiting time. Reports may only be transmitted to the base station via CBR messages, which may not be enough.

[0040] Next, we will refer to Figure 1a An improved method for resource sharing is discussed. The situation is that the mobile transceiver 14 has allocated but not fully used the resource 14R. The portion of the first resource 14R to be shared can be shared. The second mobile transceiver 16 has also been allocated the second resource 16R, but needs more resources. In order to achieve resource sharing between transceivers 14 and 16, transceiver 16 can send a request S-SR (sidechain scheduling request). The request is preferably sent from transceiver 16 to transceiver 14, as shown by the communication channel marked by S-SR. In response to the S-SR, the transceiver 14 can grant the request using a sidechain grant response S-GR sent to the transceiver 16. Of course, the donor 14 can also use S-GR to reject the request. The grant of resources S-GR enables the recipient 16 to use a portion of the resource 14R that has been allocated but is to be shared / provided / granted. Note that the part of the (first) resources to be shared / provided / granted may also be the resources used for direct communication (in case the group of UEs 14, 16 is within or outside the coverage of the BS 12). For example, the recipient user 16 sends a request to one or more user equipments in the vicinity. Note that if the message cannot be decoded by the donor 16, the request may be ignored. This principle of RRC (Radio Resource Control) is initiated by the recipient transceiver 16. This mode is called recipient user equipment (UE-T or recipient).

[0041] According to an embodiment, the mode may have the following sub-steps. The sharing intention from the recipient user UE is transmitted (in different steps) to one or more donor user UEs. The recipient user UE first starts to discover and identify nearby users and, if possible, traffic utilization. Thereafter, the recipient UE starts to announce some donor user UEs whose resources are most promising (less interference). In this case, if the nearby UEs have a higher traffic utilization, the recipient UE sends a request token with a certain power value that reaches the farther UEs, i.e. to reduce interference while the donor continues to use the resources or a subset of the resources. Depending on the situation, the sharing request should be a unicast or multicast or broadcast message.

[0042] refer to Figure 1b , another mode will be discussed, also called donor user equipment (UE-D or donor). Figure 1bThe embodiment of starts from the same configuration of the communication network 10 with the transceiver 12, the donor user 14 and the recipient user 16. Here, the sharing activation is initiated by the donor user 14 who has an allocated but part of the resource 14R to be shared. To this end, the donor transceiver 14 sends (using the side channel) a grant message S-GR for offering the part to the recipient 16. In response to the offer, the recipient 16 can use the resource directly or optionally answer so that a license acquisition can be performed.

[0043] Common to both embodiments is that grant requests S-SR and grant responses S-GR are exchanged on an additional resource request side link between the donor transceiver 14 and the recipient transceiver 16 to enhance shared resources between different users 14 and 16 with different QoS traffic requirements.

[0044] like Figure 1b As shown in the embodiment of FIG. 1 , the donor UE starts to advertise its unused resources for sharing. Here, the donor UE 14 broadcasts its unneeded resource configuration (time and frequency). This message is eventually sent on the next pre-configured (unneeded) grant on the shared resources. For example, the donor UE 14 may be requested to update the gNB (base station) of the shared resources or the amount of shared resources or the amount of provided resources in response to the offer.

[0045] From the perspective of the donor user 16, it can be described as follows Figure 1a and 1b Resource sharing of an embodiment. UE-D should

[0046] · Receive a Sidelink Scheduling Request (S-SR) and / or send a Sidelink Grant Response (S-GR) with rejected resources or announced resources. In one embodiment, UE-D will send an S-GR as a response to a specific S-SR.

[0047] • Or in another embodiment, UE-D will send S-GR as a broadcast / multicast message, announcing the shared time slot and resources to any UE (broadcast) or specific UEs (multicast / groupcast).

[0048] Therefore, both modes can meet the urgent needs of user equipment, for example, assuming that the distributed MAC operation wants to share resources from other users, such as Mode 3, where it should be noted that both user equipments, recipient or donor, can operate using distributed MAC resource allocation, i.e. as in Mode 4 LTE or NR operation like Mode 4, or both can operate using centralized MAC mechanisms, such as in Mode 3 LTE or NR in Mode 4. Note that sharing can be granted once or multiple times, with or without time periods.

[0049] According to another embodiment, the donor UE executes a priority selection algorithm and grants shared resources to selected recipient user UEs via sidelink control information regarding dedicated resources for virtual grants, preconfigured data exchange resource pools and / or exception / additional resource pools (such as common bandwidth portions).

[0050] As described above, preferably, a side chain is used to change the resource control information. According to an embodiment, sharing information can also be done through additional resource pools involved in the idea, which can also be: additional exception pools, additional reserved resource pools for real-time and critical message delivery and / or emergency exception resource pools. However, the information shared by the recipient user is not only sent through the SCI through the defined pool (such as the information in the classic Rel 15 SCI extended with the sharing bit), but also through the shared resource pool (in this case, it is the exception RP or other future RP). The main function of this resource pool should be observed by the intended sharing users (e.g., recipient and donor users).

[0051] refer to Figure 1a and 1b It should be noted that according to other embodiments, there may be other UEs in the communication system 10 that want to participate in resource sharing. All users can be divided into two modes according to their packet QoS requirements (i.e., reliability and latency) and their actual service QoS (e.g., denoted as 5GQ). Therefore, all UEs can act as recipient UEs or donor UEs.

[0052] Depending on the embodiment, the quality of service satisfaction is implemented at different levels; the quality of service may be referred to as a 5G quality of service indicator (5QI). It may be:

[0053] A requesting sharing user shall only share resources if its packet QoS constraint (i.e. 5QI: 5G QoS Identifier) ​​is above the selected QoS value QoS_sharing_request_level (i.e. can be mapped or PPPP, PPPR and / or f(PPPP)). QoS may be individual for packets / applications or users.

[0054] · The donating user can evaluate the request and grant only when QoS_requesting >> QoS_donated_packets. The recipient UE in turn sends the 5QI value, UE-ID and BSR (if possible) in the sharing request.

[0055] Deny sharing based on the following decision: QoS_requesting< <QoS_donated_packets

[0056] Users who donate their resources (i.e. users who are able to send grant responses) implement different algorithms to grant some resources and deny others. If sharing is accepted based on this algorithm, the donating user should send a grant token (as described earlier) on the shared advertised resource / pool. The grant response is sent along with the power level of the intended user. Therefore, broadcast messages can be applied and a simple grant key can be specified. The key can be decodable by each user.

[0057] Note that the Sidechain Share Request (S-SR) is also defined as Request to Send (RTS), while the Sidechain Grant Response is also known as Clear to Send (CTS).

[0058] According to another embodiment, the permission policy may be designed as follows.

[0059] Sidechain UE with different modes (distributed and centralized resource allocation)

[0060] Sidelink UEs within the same mode (mostly centralized), where some of them are using many pre-configured resources that can be shared with other UEs.

[0061] Cellular UE is pre-configured for resource and UE sidelink sharing:

[0062] ο Licensed frequency bands below 6 GHz

[0063] ο Licensed frequency bands above 6 GHz

[0064] Permitted resources can be:

[0065] o One subframe / time slot is only prepared for one-shot transmission

[0066] o Multiple subframes / time slots can be used for multiple single transmissions

[0067] οReservation time periods for multiple resources for SPS and / or preconfigured periodic transmissions.

[0068] If the message is XORed with the Grant Request Message ID, the UE attempts to decode the message without XORing first if a decodable reservation is made (if granted). If the message is not decodable, the UE repeats the message decoding after XORing with the Message ID field. The Message ID may be extended (by repetition) to cover multiple fields in a Grant message.

[0069] If the message is not encrypted, then another UE or UEs may capture the SCI information in the virtual grant request message. Any of these UEs should tune to transmit (inclusive) on the evacuated (granted) resources.

[0070] refer to Figure 2a , different situations of sharing requests and permission requests will be discussed. Figure 2a The communication between the recipient UE 16 (UE-T) and the donor UE 14 (UE-D) is shown at different time points from time t0 to t6. At time point t0, UE-T 16 sends a request S-SR using an exception / shared pool 20 with a dedicated frequency range. In response, UE-D 14 receiving the request S-SR accepts the request and sends a grant message S-GR, which can be received by UE-T 16 at t2. Here, the request S-SR and the grant S-GR can be sent using different frequencies within the frequency band of the shared pool 20.

[0071] Thus, it appears that a sharing request is sent over the air (OTA) on a shared / exceptional pool or a predefined set of resources. Although not explicitly shown, the sharing message sent, for example, at t0, may be received by one or more user equipment, for example, at t1. As a response to the request at t2 / t3, as shown by S_GR, which is equivalent to rejecting the transmission at t4, UE-D 16 may also reject resource sharing. If the received message allows sharing, then according to an embodiment, the resources granted to the recipient UE14 (i.e., the mode of the UE) may be included in the response.

[0072] The transmission power for requesting S-SR and eventually for S-GR may have limited transmission power. Limiting the transmission power can define the communication range and ensure that no interference range beyond the defined range is caused. Figure 2b The communication range of two recipient UEs 16_1 and 16_2 with multiple potential donor UEs 14_1 to 14_8 is shown by two circles surrounding the recipient UEs 16_1 and 16_2. Around each recipient UE 16_1 and 16_2, two circles 21 are shown, which represent the limited transmission power. Within each circle 21, the multicast / unicast of the S-GR is depicted. In detail, the S-SR of UE 16_1 can be received by potential donor UEs 14_1 to 14_3, but cannot be received by UEs 14_4 to 14_8. Vice versa, potential donor UEs 14_6, 14_7 and 14_8 can only receive the S-SR of 16_2. UEs 14_4 and 14_5 do not receive any S-SR.

[0073] The UE requesting resources shall continue to use the discovery mechanism to select neighboring UEs, i.e. if the UE needs to multicast or unicast its scheduling messages. All these UEs are assumed to be active UEs, even if they are in RRC idle state or not connected. If the discovery mechanism indicates that there are multiple layers of UEs around the recipient user UE, and if necessary, one or more requests shall be sent at the primary (maximum) achievable power (see for more details). Figure 6)。Any other UE for which the communication range is not the target receives the resource scheduling request (borrowing) message in its interference range (i.e., with a very weak power signal). Therefore, power selection must be carried out accurately to avoid multiple reservations.

[0074] According to an embodiment, a threshold for determining whether the donor will coexist with the recipient on the donated resources: Compare the scheduling request message received at the donor UE with a defined threshold (Thr). The reason here is to encourage the donor UE to accept more permission request messages from relatively distant UEs. In this case, the donor UE can decide to use the donated resources because the location of the recipient UE is far from its possible communication range, that is, in this case, the shared power should be restricted to avoid interference.

[0075] Figure 3 Illustrates how, according to an embodiment, the permission request UEs 16_1 to 16_4 should select power based on the discovered location of the potential donor UE 14. If the discovery does not generate information, the permission request UE selects a high power range for better reachability. Refer to Figure 3 , it is clear that the selection of the transmission power of the GR message must exceed a certain threshold (see UEs 16_1 and 16_2, but not the non-received requests of UEs 16_3 and 16_4). If not, the received power will be too low to be dedicated to the donor UE 14.

[0076] Preferably, if the power level is within a predetermined range of the threshold when sharing is required, the permission is executed or that part is provided: for example, UE2-T may have an RX power level within this range (higher than the RX power of UE1-T) (high power indication is too close) and lower than UE3-T (low power level). In addition, if the power level is lower than a second threshold (<<Thr), and if sharing is not required, the permission is executed or that part is provided. This can be effective for UE3-T. Therefore, the second threshold can be less than the threshold of the range, or can be defined by the low power level threshold of the range.

[0077] Below, embodiments based mainly on Figure 1b will be discussed, where further details will be discussed, especially regarding spontaneous sharing and regarding optional handover steps. Refer to Figure 4 for discussion.

[0078] Figure 4The resources for exchanging resource control information marked by reference numeral 20 and the resources to be shared / granted marked by reference numeral 23 are shown. As shown, resource sharing is performed with respect to time frames SF11 to SF 19, and also with respect to different subchannels belonging to the time frames, as can be seen with respect to SF 15 or SF 14. Resource control information is exchanged within the resource 20, wherein so-called toggles are used. A toggle may indicate that a resource is free, wherein there is no toggled field enabling the resource to be reserved. The toggled field is marked by reference numeral 20T.

[0079] In the sharing activity shown, the donor UE starts offering its resources for sharing using the Sidelink Grant Response (S-GR) message without receiving an S-SR. In this case, a mode is introduced in the sharing activation message sent by the network to allow spontaneous sharing.

[0080] S-GR is a control message (or shared data channel, with controlled multiplexing within the data) which can contain:

[0081] - Selected resource pool or preconfiguration

[0082] -RIV (Redundant Incremental Version) location

[0083] - Maximum number of subchannels (N subchannels or L-PRBs)

[0084] - Toggle field to indicate whether the shared resource is still available in the next time slot.

[0085] The switch is considered as a signal indicating whether the donor is allowed to share its resources in the next time slot. If the switch field = is a short indication flag (allowed or not).

[0086] For example, the switch may be performed as follows:

[0087] S-GR (or Clear to Send (CTS)) is transmitted on preconfigured / shared / excepted resources. This can also be a licensed band for Mode 3 or Mode 4 LTE. This can also be a portion of the common bandwidth used to exchange shared messages, such as Resend Request (RTS, aka S-SR) or Clear to Send (CTS, aka S-GR):

[0088] o When it is a pre-configured exceptional resource in parallel with the provided resource, the S-GR may point to a subframe (or timeslot) on a subsequent subframe (or timeslot).

[0089] o If there are shared resources for S-GR transmission in the LTE resource pool, one or more pre-arrived subframes may be designated in the S-GR to share the resources (collectively referred to as subframes).

[0090] o If dynamic activation and deactivation of switching control is not supported, S-GR may consume the entire subframe or timeslot.

[0091] For LTE shared resources, if the subframes of NRV2X and LTE shared control resources are not aligned, switching control is not supported.

[0092] If handover is supported (for dynamic activation and deactivation of UE-D), the handover control field may consume a subslot-based time (minimum slot duration) before the start of the S-GR subframe. Therefore, the S-GR subframe should partially use the following subframe (i.e., to allow the handover field of the next cycle to be transmitted at the end of the S-GR).

[0093] o Therefore, if a UE receives an internal message with a higher priority (i.e. higher than the priority of the recipient UE data packet), the UE should send a busy handover value on the mini-slot (as UE1-D does in subframe 17 to disable sharing on subframe 18).

[0094] o If the UE has sent an Activate Handover message, the UE may schedule its emergency transmission to another timeslot. If sidelink sharing (puncturing supported):

[0095] If the donor UE misses the deactivation handover transmission opportunity and its data is highly proprietary, the UE may puncture one or more mini-slots to send its own data value.

[0096] o Puncturing can be performed by increasing the power of the donor UE's emergency transmission.

[0097] Therefore, the power added for the mini-slots selected for puncturing is power-2

[0098] ο Assume that the recipient UE will not transmit at a power higher than power-1

[0099] o Therefore, power-2>>power-1 (as in UE2-T and UE2-D in subframe 19).

[0100] According to another embodiment, a puncturing mechanism may be used. According to this, the donor UE has a time period to donate partially or completely. The recipient UE reacts passively, i.e., the UE-T scans the shared resource pool for sharing. If the pool indicates the current S-GR subframe, the recipient UE may only be able to capture the frame in the next transmission opportunity (such as in SF 16, where UE3-D announces sharing). This embodiment can be summarized as follows: The switching mechanism allows signaling (e.g., using Layer 1 SCI) to activate and deactivate sharing on one or more multiple transmission opportunities.

[0101] According to another embodiment, the resources virtually granted by the donor UE may be fed back to the base station for further analysis. The amount or ratio of granted resources will be sent to the base station to indicate the shared traffic. The base station may receive the report during one of the measurement reports on the UL. The successful sharing percentage may be sent as an index quantized into 3 bits (i.e., 8 levels) (indicating the successful sharing percentage quantization bits).

[0102] Bit-Field percentage 000 0％ 001 12,5％ 010: 25％ … … 111 100％

[0103] This feedback information can be used to offload pre-configuration to the requesting mode / UE if possible. If not, the base station can find supplementary resources for the donor UE on the same or higher frequency.

[0104] According to another embodiment, matching users of mode and QoS information are used for selecting permitted resources, or generally for resource sharing algorithms. In the following, we describe the operation of D-UE and UE-T in V2X. Let us now assume that UE-D is a mode 3-like UE and the recipient user is a mode 4-like UE, i.e., one for network-assisted resource allocation and the other for autonomous (distributed) resource allocation mode, respectively. In mode 3-like operation, the base station configures a grant for a single transmission and pre-configures a grant for unlicensed access transmission (from Rel 15 NR onwards). In both cases, it is assumed that if there is a network coverage (through one or more base stations), it pre-configures certain resources to process (exchange) a grant proposal in one mode and carry the returned backhaul scheduling grant. UEs in higher 5QI value modes are able to grant one or more UEs at a time on one or more of their consumed (pre-configured or permitted) resources.

[0105] Let us assume that Mode 3 or Mode 3-like users are users of licensed resources that are pre-configured or used primarily for semi-persistent scheduling. Other resources can be based on one-time resources that occur in later subframes (if possible, according to the new radio definition, resources can be pre-configured).

[0106] In our context: Mode 3 UE refers to: higher priority UE, sidelink UE with Mode 3 configuration and / or any UE with similar Mode 3 operation for NR design with RRC connection / network connection based on network scheduling. Mode 3 can also be denoted as Mode 1 (for sidelink non-V2X UE).

[0107] According to another embodiment, the QoS flow-aware selection and matching mechanism can be implemented as follows. Figure 5a Discuss the implementation.

[0108] Figure 5aA donor user process 100 for resource sharing is shown. Here, a donor UE (UE-D) initiates the method, as shown in method step 105. The first step is 110: initiate UE-D grant based on SPS. Here, the UE-D acquires SPS, pre-configured resources or random grant (single transmission); the donor UE may not need to consume all possible resources. In addition, the donor UE may not be transmitting high reliability and / or low latency data. This step 110 may have three optional sub-steps 112, 114 and 116. In step 112, it is checked whether the SIB is received within a sharing command. If the donor UE receives a SIB command with sharing activated (for example, in LTE SIB 18, 19, 21 for sidelink in LTE, this may be different for new radio), the following rules apply:

[0109] o The donor UE identifies the sharing command for possible RSSI thresholds to respond (see step 114)

[0110] ο Donor UE identifies sharing command PPPP / PPPR / QoS flow level to evaluate sharing and priority decisions

[0111] o The donor UE identifies the shared preconfigured resource size (in frequency and time), the starting index and its periodicity in the shared signaling. The preconfigured resource may also be a preconfigured pool used only for emergency situations. It may also be one of the "exceptional pools" or "exceptional pools" to handle the problem with RLF (Radio Link Failure) or congestion resolution.

[0112] Regarding step 116: Once the Mode 3 UE identifies the shared resource (pool), it starts scanning the shared resource for possible grant requests from lower priority UEs (possibly a recipient UE or a UE similar to a recipient UE or a congested donor UE or a congested donor UE similar to a donor UE).

[0113] If sharing is received (see step 100), the donor UEs analyze the request and identify whether they should tentatively accept the sharing request or reject the sharing request. If the UE accepts sharing, and if the received RSSI is less than a (predefined) threshold, low priority UEs are allowed to coexist.

[0114] If the RSSI is high (see steps 122 and 124), and the donor UE has redundant resources, it decides to share without coexisting (the UE donor UE decides to prohibit transmission on the shared resources).

[0115] Once the donor UE is accepting sharing (see step 126a or 126c), the donor UE sends a sharing acceptance short data with a short (or if not possible, a long) P(U / S)CCH containing the resource allocation to be shared that has been accepted. The donor UE only sends the time offset, the starting PRB and the length of the PRB. If the UE will grant a full SPS or a preconfigured time period, this time period must also be added.

[0116] As indicated by step 130 , the message is sent as unicast (for a single UE), multicast (for multiple licensed UEs), or broadcast if unicast and multicast are not possible. As indicated by endpoint 132 , step 130 is the final step of method 100 .

[0117] With respect to method 100 , it should be noted that there are some optional steps, such as 112 , 114 , 116 , 122 , and 124 .

[0118] Next, we will refer to Figure 5b The operation sequence of the recipient user equipment is discussed. Method 200 starts from point 205. The resource demand user is performing distributed MAC scheduling and / or centralized resource allocation. However, in any case, the UE urgently needs to eventually use the resources that are not available. Here, UE-T starts with distributed MAC, as shown in step 206.

[0119] In step 210, the UE scans the SIB for sharing configuration, and if identified, then:

[0120] -UE scans the SI share command to get detailed information about sharing:

[0121] Donor UE resource pool information, bitmap, starting RB, subchannel length (see step 215)

[0122] Public search space on sidechains (shared pool for shared handshakes, possibly exception pools with exception definitions).

[0123] To avoid interference to the S-SR, the sharing request is randomized (a pseudo-random pattern (PN sequence) is used to randomize the request to avoid collisions, and the NOMA concept may also be applied) (see step 220)

[0124] o If the PN pattern is defined or pre-configured by the network, the UE is requested to send a sharing request using this pattern.

[0125] Otherwise, if the UE does not know any pattern, it shall send sharing requests in a non-random manner. (See step 221)

[0126] In step 230, the grant requests on the preconfigured resources for message exchange defined previously are summed. After sending the grant, the requesting UE starts a timer T_timer_grant_response (see 231).

[0127] If the timer T_timer_grant_response has not expired:

[0128] Check if a permission response is received (see 232),

[0129] If yes, use the shared resources in S-GR (see 233 and 234)

[0130] If you do not receive permission, please continue to wait.

[0131] Otherwise, if the timer expires:

[0132] UE-T selects another way to share resources, for example based on sensing (see 235 ).

[0133] refer to Figure 6 , the mechanisms used for power control will be discussed.

[0134] Power of the request message: Based on the discovery mechanism, multiple power levels may be selected to transmit the request from the recipient UE. If the discovery information is not available, the maximum power shall be selected in this case. The UE may attach a power level (2 (4 levels) or 3 (8 levels) bits) identifying the power control value to the donor UE. This value may be used to determine the Thr of the received S-SR.

[0135] Power of message response: If the donor UE is receiving a request to share message, and if the power level can be decoded, the donor sends a grant response using the same or higher power value. If the donor UE cannot decode the power control, the grant response will be sent using the maximum power.

[0136] Shared donor resource pool: Based on the result of the threshold check in mark (A) Figure 4 ), the donor UE may specify the shared power value in the grant response message. If the result in the marking is low, and the donor UE will use the shared resources accurately (when the recipient UE is far away), the donor UE may choose one of the low power levels. Otherwise, if the result of the marking is that the power exceeds the threshold, the donor UE may not reuse the resources (the recipient UE is close enough to the donor UE), and a higher power level may be recommended for the recipient UE.

[0137] According to an embodiment, it is recommended that UE-D announce or inform the BS of the donated resources. If the donor UE receives a specific S-SR, the donor UE should inform the BS of possible activities regarding the donated resources. This information can be provided using a specific control channel or a regular data channel.

[0138] According to a further embodiment, if the traffic is high or the shared resource regularity cannot be ensured, the BS will deactivate the sharing mechanism on some resources (selected resources) or all resources. According to a further embodiment, the UE-D may announce the selected UE5QI / QoS.

[0139] According to an embodiment, the BS will also indicate the minimum acceptable shared 5QI / CQI in the RRC message. In this case, in the first mechanism (sharing request and grant), UE-D will accept UE-Ts with higher or equal 5QI / CQI than the minimum. In the other mechanism (UE-D grant request only), only UE-Ts with minimum 5QI and higher values ​​can start sharing the announced resources.

[0140] In the above embodiments, the invention has been mainly discussed in connection with general mobile transceivers. Preferred applications are V2X, D2D, mMTC, URLLC, critical communications. A further application is a high traffic scenario of V2X where some / few / single UEs request resources to transmit high priority data (e.g. due to unexpected damage or accident of previous vehicle, while other UEs in the vicinity do not (urgently) need the granted resources).

[0141] Another embodiment relates to a mobile device, such as a mobile phone or a vehicle, using the resource sharing mechanism described above. According to a first embodiment, if the transceiver needs more resources, the transceiver of the device can initiate resource sharing with a request. According to a second embodiment, if the transceiver has a portion of resources, it can initiate resource sharing by offering resources.

[0142] In the above embodiments, the step of exchanging resource control information should be understood as one-way communication (for example, if the donor UE provides resources without feedback or request), and can also be understood as two-way communication (for example, UE-T's request, and UE-D provides / permits as a response to the request).
