DETAILED DESCRIPTION OF THE INVENTION

[0009] A method and method for prioritizing transmission of V2X sidelink communications over uplink (UL) transmissions The present disclosure provides an extended V2X management object (Management Object) and an apparatus for implementing the same. A User Equivalent Object (MO) is described herein, which is a It can be used to provision V2X configuration parameters to the UE. (1) Sidelink logical channel prioritization (LCP) can be implemented. (2) implementing UL Data LCP to address the impact of SL-related transmissions; and (3) For scenarios where V2X traffic priority relative to UL traffic changes dynamically , determining the priority of transmission of V2X sidelink communication relative to UL transmission; and In the embodiments described herein, the term "V2 "V2X Service", "V2X Message" or "V2X Application Data Packet" are sometimes used with the same meaning.

[0010] The techniques described herein are applicable to New Radio (NR) networks, which are more diverse and demanding than LTE V2X. Considering the V2X (Vehicle to X) communication requirements, we will solve the sidelink LCP problem. These techniques are based on the traditional system prioritization as opposed to the relative priority between SL and UL transmissions. Such prioritization in the system is dependent on the absolute sidelink LCH configured in the UE. Taking into account the fact that it is based on prioritization, This solves the problem of inter-UE prioritization between sidelink and uplink transmissions.

[0012] NR V2X use cases and requirements are addressed by the techniques described herein. The SA1 is a state-of-the-art design that takes into account new applications desired in the automotive industry. It has clarified numerous use cases for V2X services. These service use cases include vehicle platooning, extended sensors, and advanced These can be categorized into four modern use cases: driving, remote driving, and remote operation.

[0013] Vehicle platooning allows vehicles to dynamically form a convoy that travels together. Each vehicle in the platoon obtains information from the lead vehicle that manages the platoon. This information is coordinated so that each vehicle is traveling in the same direction and together, This may allow vehicles to drive closer together than usual.

[0014] The expanded sensors are used in vehicles, road site units, pedestrian devices, and V2X applications. raw data collected through local sensors or live video images across application servers or transforming the processed data. Vehicles can use their own sensors to Improve your awareness of your surroundings and get a broader picture of the situation beyond what you can do. High data rates allow for an extensive sensor usage scenario. This is one of the characteristics of the Rice Group.

[0015] Advanced driving enables semi-automated or fully automated driving. Each vehicle and / or RSU When a vehicle shares its own perception data acquired from its local sensors with nearby vehicles, This allows the vehicles to synchronize and coordinate their paths or maneuvers. Similarly, each vehicle may share its driving intentions with nearby vehicles.

[0016] Remote driving is not permitted by passengers themselves or the remote vehicle in dangerous situations. For passengers, remote drivers or V2X applications can operate remote vehicles. As in the case of public transport, there are limitations on the form of variation and the route is predictable. Where possible, cloud computing-based operations may be used. Reliable and low latency are key requirements for the Remote Driving use case group.

[0017] Figure 1 shows an overview of 5G eV2X requirements versus LTE V2V R14 requirements. The target data rate for eV2X is, for example, Data rates are about 100 times higher than the 1 to 10 Mbps range, at over 1 Gbps Similarly, the target end-to-end delay 52 for 5G eV2X is, for example, 3 to 5 m, 5 to 20 times lower than the 20 to 100 ms range of Rel-14 V2V The target communication range 53 of 5G eV2X is, for example, LT E Rel-14 V2X's range of 100 to 320m is 2 to 3 times wider, 1000 The target accuracy of 5G eV2X positioning is 54, even if For example, 0.1 to 15m range, 10 times higher than the 5 to 15m range of LTE Rel-14 V2X. Improved accuracy with a range of 0.5m. Similarly, target mobility for 5G eV2X. The relative speed 55 is twice as high as, for example, 280 km / h for LTE Rel-14 V2V. The increased target relative velocity is 550 km / h. Target reliability56 is, for example, 1000% higher than 90% for LTE rel-14 V2V. The reliability requirement is improved to over 99.99%, twice as high.

[0018] Figure 2 shows the non-roaming architecture for PC5 and LTE-Uu based V2X communication. The V2X control function 201 controls network-related operations required for V2X. The V2X control function 201 is a logic function that may be used to The V2X control function 2 may communicate with the V2X application server 202 via the V2X control function 2. 01 is a parameter required for V2X communication (e.g., destination Layer 2 ID, Radio resource parameters, V2X application server 202 address information, service UEs (e.g., UE 205a, UE 205b) using a mapping between V2X frequency and V2X type. 05b, UE205c or UE205d) These parameters may be pre-configured in the UE or may be configured when in coverage. ,V in the Home Public Land Mobile Network (HPLMN) The provisioning is performed by signaling from the 2X control function 201 through the V3 reference point 210. The UE may transmit V2X control information to V2 through the V3 reference point 210. V2X control function 201. application 204a, V2X application 204b, and V2X application 20 4c or V2X application) each UE (e.g., UE 205a, U Each V2X may be associated with a UE (UE205b, UE205c, or UE205d). Applications may communicate over V5 reference points 212. V2X applications The application communicates with the V2X application server 202 via the V1 reference point 219. There are cases where this happens.

[0019] A UE (e.g., UE 205a, UE 205b, UE 205c, or UE 205d) via the LTE-Uu interface 213, the evolved UMTS terrestrial radio access network The E-UTRAN 206 may communicate with the S1 interface. The mobile station 207 accesses the mobility management entity (MME) 207 via an interface 214. The V2X Control Function 201 may communicate with the home subscriber via the V4 reference point 218. The MME 207 may access the S6a reference point 21 V2X Application Server 2 may access the HSS 209 via 5. 02 communicates with the PDN Gateway or Serving Gateway via the SGi reference point 216. When accessing PDN Gateway or Serving Gateway (S / P-GW) 208 be.

[0020] When PC5 211 is used for transmitting V2X messages, Scheduled operation mode (e.g., mode 3) and UE autonomous resource selection mode (e.g., In both modes (e.g. mode 4), the following principle may be used: ProSe per-packet priority (PPPP) is used for V2X communication via PC5 211. It can be applied to faith. The application layer must determine the V2X message before sending it to the lower layer for transmission. PPPP can be set up. Mapping of application layer V2X message priorities to PPPP is done by the UE. It may be configured. The PPPP value setting is based on the delay required by both the UE and the evolved Node B (eNB). For example, a low Packet Delay Budget (PDB) may reflect a high priority It may be mapped to a PPPP value. Mapping between V2X service types and V2X frequencies. Layer 2 ID of the destination and the V2X service, e.g., V2X application (e.g., V 2X application 204a, V2X application 204b, V2X application PSID or ITS-AID of the V2X application 204c or V2X application 204d Mapping with. Mapping PPPP to packet delay budgets.

[0021] When the network scheduled operation mode is used, the following principles apply: There are cases where this happens. The UE can provide PPPP-reflected priority information to the eNB in the resource request. When the eNB receives a request for PC5 resources from the UE, the eNB From the PPPP-reflected priority information, the packet delay budget can be inferred. The eNB uses PPPP-reflected priority information for priority handling, UE-PC5-AM for capping UE PC5 transmissions in resource management BR can be used. The UE can provide the Layer 2 ID of the V2X service destination to the eNB in the resource request. . When the eNB receives a request for PC5 resources from the UE, the eNB The system can determine the V2X frequencies on which service will be scheduled.

[0022] When the autonomous resource selection mode is used, the following additional principles apply. Based on the provisioned mapping information, the UE can A packet delay budget for the message can be derived. The UE determines the V2X service from the mapping between the V2X service type and the V2X frequency. The frequency at which the service will be transmitted can be derived.

[0023] Figure 3 shows the P for V2X communication through PC5 in LTE V2X communication provisioning. The configuration parameters of the LTE V2X MO300 configuration via C5 communication are shown.

[0024] FIG. 4 shows configuration parameters in the form of a geographic area (GA) MO 400 .

[0025] For sidelink HARQ operation, several parallel SL-SCHs are used for transmission. To the Media Access Control (MAC) entity that may continue sidelink processing. There may be one sidelink HARQ entity, e.g., V2X sidelink In the case of sidelink communication, the transmit sidelink processing associated with the sidelink HARQ entity The maximum number of logics may be eight.

[0026] A sidelink process may be configured for the transmission of multiple MAC PDUs. For example, in the case of transmission of multiple MAC PDUs, transmission using a sidelink HARQ entity is The maximum number of sidelink processes provided and configured may be 2. The sidelink grant and its associated HARQ information are associated with the sidelink process. The sidelink processing may be associated with a HARQ buffer. The sidelink processing is the process of processing multiple MAC PDUs for V2X sidelink communication. If configured to perform transmission, the process uses the counter SL_RESOURCE_RESELECTION_COUNT For other configurations of sidelink processing, this counter may be used Sometimes it's not possible.

[0027] V2X sidelink communication transmissions have priority over UL transmissions if the following conditions are met: This may be the case. The MAC entity performs UL transmission and V2X sidelink transmission simultaneously. If you cannot. · UL transmission is not prioritized by higher layers. The highest priority value of a sidelink logical channel in a MAC PDU is thresSL-TxPr If it is less than ioritization.

[0028] A UE may establish multiple logical channels. The Physical Channel Identification (LCID) identifies one source Layer 2 ID and one destination Layer 2 ID. The logical channel can be identified within the range of combinations of D. The access stratum (AS) may be configured by the upper layer to provide a PC5 interface. Each logical channel may be provided with a PPPP for PDUs sent through the interface. There may be a PPPP associated with the PDU. The PDB of the PDU is determined from the PPPP. A low PDB may be mapped to a high priority PPPP value.

[0029] When a new transmission is made, the Sidelink LCP procedures may apply. Each sidelink logical channel has an associated priority which may include PPPP. Multiple sidelink logical channels may have the same associated priority. The mapping between priority and LCID may be left to the UE implementation.

[0030] The MAC entity shall transmit the sidelink communication during the Sidelink Control (SC) period. For each Sidelink Control Information (SCI) that is sent or for each new For each SCI corresponding to a transmission, the following LCP procedures may be performed:

[0031] The MAC entity allocates resources to sidelink logical channels in the following steps: There may be cases where this is assigned.

[0032] This SC period in order to have data available for transmission in the sidelink communication, and Sidelinks that are not pre-selected during SC periods (if any) that overlap with this SC period Consider logical channels.

[0033] Among the sidelink logical channels that have data available for transmission, the highest priority Select a ProSe destination with a sidelink logical channel.

[0034] For each MAC PDU associated with an SCI, the following steps may be performed: Sidelink logic that belongs to the selected ProSe destination and has data available for transmission Among the channels, resources are allocated to the sidelink logical channel with the highest priority. If resources remain, data or SL grants for sidelink logical channels The sidelink logical channel belonging to the selected ProSe destination is used up until either of them is exhausted first. Channels may be run in descending order of priority. Side links configured with equal priority Link logical channels may function equally well.

[0035] During the above scheduling procedure, the UE may follow the following rules: If all SDUs (or partially transmitted SDUs) fit into the remaining resources The UE then sends the radio link control (RLC) SDU (or a partially transmitted SDU) to the Do not segment. When the UE segments an RLC SDU from a sidelink logical channel, You may want to maximize the size of the segments to fit as many entries as possible. · Maximize data transmission. 10 bytes or more (for sidelink communication), or 11 bytes or more (for V2X sidelink communication) The MAC entity provides the sidelink grant size for the At the same time, if the MAC entity has data available for transmission, it You can't just send

[0036] The above sidelink LCP procedure involves avoiding starvation of lower priority channels. To avoid this, logical channel priority bit rates, etc., are used for Uu interface logical channels. There is no provision similar to that used for prioritization procedures. Sidelink logical channel procedures may include delay constraints, numerology constraints, or Constraints such as allowed serving cell constraints (e.g., when packet duplication is supported) To meet the requirements imposed by the NR LCP procedure, Constraints on the logical channels that can be served by a given resource grant. There is no specific provision for

[0037] In LTE or NR, information about the UL data volume of the MAC entity is , buffer over the Uu interface to provide to the serving eNB or gNB The Fast Status Report (BSR) procedure may be used. Also, the sidelinks available for transmission in the SL buffer associated with the MAC entity The sidelink buffer is used to provide the serving eNB with information about the amount of data Radio Resource Control (RRC) may use the QoS status reporting procedure. ) is achieved by configuring two timers: periodic-BSR-TimerSL and retx-BSR-TimerSL. The BSR reporting for the sidelink may be controlled by the Each sidelink logical channel may belong to a ProSe destination. Link logical channel prioritization, and LCG ID and priority provided by higher layers Depending on the mapping between the priority and the logical channel group (LCG), LCG may be defined for each ProSe destination. Similar to the sidelink BSR, the sidelink BSR can be a regular BSR, a periodic BSR, or a padding BSR. It may be a BSR.

[0038] By the time the first sidelink BSR is sent, multiple events may cause the sidelink Even if a sidelink BSR is triggered, the MAC PDU is sent to at most one sidelink BSR. It may contain a MAC Control element, in which case it will include a regular sidelink BSR and a peripheral The primary sidelink BSR may have a higher priority than the padding sidelink BSR. There is a match.

[0039] If the MAC entity receives an SL grant, it restarts retx-BSR-TimerSL. There is.

[0040] The remaining configured SL grants are used to transmit all available packets in the V2X sidelink communication. In cases where the binding data can be effectively applied, all triggered rules The sidelink BSR may be cancelled. The case where there is no data available for transmission on any of the link logical channels. In this case, a triggered sidelink BSR may be cancelled. When a BSR (except for the shortened sidelink BSR) is included in a MAC PDU for transmission A triggered sidelink BSR may be cancelled. Configuring source selection cancels all triggered sidelink BSRs and The retx-BSR-TimerSL and periodic-BSR-TimerSL may be stopped.

[0041] A MAC entity may transmit at most one regular / periodic sideband packet in a Transmission Time Interval (TTI). A MAC entity may transmit a link BSR. When a DU needs to be transmitted, the MAC entity Any MAC PDU that does not contain a link BSR may contain a padding side link BSR. This may occur.

[0042] All sidelink BSRs sent in a TTI are sent only if a MAC PDU is constructed during the TTI. Each LCG may have at most one buffer per TTI. A buffer status value may be reported, and this value reports the buffer status of this LCG. It may be reported on all sidelink BSRs that are available.

[0043] Padding Sidelink BSR triggered by regular / periodic Sidelink BSR In some cases, it may not be possible to cancel the SR. Padding sidelink BSRs are The trigger may be triggered for a specific MAC PDU, and the trigger occurs when the MAC PDU Once constructed, it may be cancelled.

The example in FIG. 5 includes a destination index field 501, a report One LCG ID field 502 and one target group for each target group advertised. a BSR MAC Control Element (CE) containing a corresponding buffer size field 503; Sidelink BSR and shortened Sidelink BSR MAC CE are shown. The field 501 allows identifying the destination of the V2X sidelink communication. The length of this field may be, for example, 4 bits. The value is The index of the destination reported to the eNB as part of the V2X destination list in the information message. The LCG ID field 502 may be set to This field can identify the group of logical channels for which the The length of the field may be, for example, 2 bits. After all MAC PDUs are constructed during the TTI, all LCGs of the ProSe destination are The total amount of data available across the logical channels can be identified. The amount of data is sometimes expressed in bytes. It may contain all available data. The LCG buffer size is the destination index file. The highest priority sidelink logical channel belonging to the LCG is used regardless of the value of field 501. May be included in descending order from the top.

The SR configuration may consist of different Bandwidth Parts (BWP) and Cell For logical channels, it may contain a set of PUCCH resources for SRs spanning In addition, a maximum of one PUCCH resource in the SR is configured per BWP.

[0048] Each SR configuration may correspond to one or more logical channels. Each logical channel may be mapped to 0 or 1 SR configuration, which is configured by RRC. The SR configuration of the LCH that triggered the BSR, if such a configuration exists, is The SR configuration may be considered to correspond to the SR configuration of the SR.

[0049] In the case of a BSR triggered by the expiration of the BSR retransmission timer, The corresponding SR configuration is the highest available data for transmission at the time the BSR is triggered. The SR configuration of the priority LCH (if such a configuration exists).

[0050] RRC may configure the following parameters for the scheduling request procedure: There is a match. ·sr-ProhibitTimer (per SR configuration). ·sr-TransMax (per SR configuration). ·sr-ConfigIndex.

[0051] The following UE variables may be used for the scheduling request procedure: . ·SR_COUNTER (per SR configuration).

[0052] When an SR is triggered and there are no other pending SRs corresponding to the same SR configuration ,The MAC entity may set the SR_COUNTER of the corresponding SR configuration to 0.

[0053] Once triggered, an SR may be considered pending until it is canceled. be.

[0054] When a MAC PDU is transmitted, all triggered MAC PDUs are reassembled. Pending SRs are either cancelled or the respective sr-ProhibitTimer is stopped. This PDU may contain a BSR MAC Control Element (CE). This BSR MAC Control Element (CE) is responsible for the MAC PDU assembly. Contains the buffer state up to (and including) the most recent event that triggered the BSR. The UL grant can accommodate all pending data available for transmission. In this case, all pending SRs may be cancelled.

[0055] Only PUCCH resources on the BWP that are active at the time of the SR transmission opportunity are valid. It may be thought that...

[0056] In Rel-15, sidelink packet duplication is supported for V2X sidelink communication. The sidelink packet for transmission may be transmitted and implemented in the PDCP layer of the UE. Regarding packet duplication, PDCP PDUs may be duplicated in a PDCP entity. Duplicate PDCP PDUs of the same PDCP entity are sent to two different RLC entities. are sent to the same entity and are associated with two different sidelink logical channels respectively. Duplicate PDCP PDUs of the same PDCP entity may be It may be transmitted on a sidelink carrier. Autonomous resource selection (in its RRC state) The UE will autonomously perform sidelink packet replication based on (pre)configuration. Scheduled Resource Allocation In the case of (Mode 3), the eNB sends ProSe packets for V2X transmissions requested by the UE. The UE is notified of the packet reliability (PPPR) information that it has in its buffer. The amount of data associated with the PPPR value(s) being used and the amount of data that the UE buffers The destination of the V2X message associated with one (or more) PPPR values in May include.

[0057] The primary use cases supported by Release 14 LTE V2V are 1 to 10M It includes basic security at relatively low data rates in the order of bps, where position, velocity, Vehicle state information, such as direction of travel, is sent to nearby vehicles, infrastructure nodes, As V2X applications advance, the status of the vehicle itself will be monitored. The sending of short messages about vehicle state data is done through raw sensor data, vehicle intent data, and This will be complemented by the transmission of larger messages containing data, future maneuvers, and confirmations. For these modern applications, the required data rates The expected requirements to meet are speed, reliability, latency, range, and speed as shown in Figure 1. The throughput of modern V2X applications can be 100x higher throughput than LTE V2X basic safety applications For example, it is expected that the UE will share the V2X applications it supports. Raw sensor data can require data rates as high as 1 Gbps. The NR LCP procedure for sidelink communication is the same as the LTE sidelink LCP procedure. or the newly defined NR Uu interface LCP procedure. Each of these has its own limitations on the NR sidelink requirements.

[0058] The current LTE V2X LCP procedure for sidelink data transmission has several limitations. At least the following restrictions apply:

[0059] (1) Primarily supports low data rate transmissions without inherent logical channel starvation avoidance mechanisms. For example, the current LTE sidelink LCP procedure is designed to work for applications with high data rate requirements. To avoid starvation of low priority logical channels by high priority logical channels, For example, it does not support specific mechanisms such as prioritized bitrate.

[0060] (2) Supports the following constraint mapping configuration for each sidelink logical channel: It is not designed to

[0061] (2a) Subcarrier spacing (SCS) transmission constraint.

[0062] (2b) Tolerable delay constraints, e.g., NR side similar to NR Uu interface A link may be characterized by variable transmission opportunity timing or variable transmission duration. As a result, sidelink logical channels are allocated to the same logical channel due to the logical channel delay tolerance requirements. may be restricted to using certain resource grants.

[0063] (2c) Other restrictions, such as data duplication restrictions and RAT / 3GPP release coexistence restrictions. Potential constraints, such as carrier frequency constraints, RAT constraints or 3GPP release constraints Taking into account the need for a coordinated design, e.g., to support different RATs or 3GPP releases. Considering the coexistence of multiple V2X devices with wireless capabilities, some of these limitations , which may be seen in LCP procedures.

[0064] (3) The criteria for selecting a sending destination (e.g., ProSe destination) during the LCP procedure are ,The priority of the logical channels towards the destination, especially the logical channel with the highest priority (e.g. Furthermore, at a given transmission opportunity, once selected, other destinations are considered. All logical channels of a selected destination must be functional before a further logical channel can be selected. In LTE V2X, the UE is configured with a mapping between PPPP and PDB. This mapping is left for implementations to choose from, but is not specified. One problem with this destination selection approach is that it is difficult to provide services beyond basic safety services. In the case of NR V2X with a diverse set of destinations, some destinations may have higher priority. Data on the highest priority logical channel is served by the selected destination's lower priority channel. In the meantime, their transmission delay requirements may not be met and may even be discarded. Another problem with current LTE V2X transmission destination selection approaches is that they do not allow for logic other than the tolerable delay constraint. Ability to efficiently allocate resource grants while taking into account channel mapping constraints Current destination selection approaches must select at least the highest priority logical The channel has an available grant or its transmission time falls within the next available grant. Runts also prevent the function from functioning, and the tolerable delay requirements cannot be met, and the data transmission destinations with unnecessary risk of being lost and radio resource grants being wasted It may be a choice.

[0065] The NR Uu LCP procedure specifies priority data rates, SCS constraints, and allowable delay constraints. High data rate with specific mechanisms to support any logical channel mapping constraints It is designed to support the NR Uu interface requirements. Although designed for text, it does not have the ability to select destinations or other potential arguments. Supports physical channel mapping constraints (e.g., service to frequency mapping constraints) Not yet.

[0066] In view of the above discussion, the existing LTE sidelink LCP procedure and the NR Uu A new NR sidelink LCP procedure based on the LCP procedure is required. Also, the grant type (e.g., mode 3 or mode 4 grant type) is The possible impact on CP procedures also needs to be investigated.

[0067] In Rel-15 LTE, during the LCP procedure, the MAC entity: may take into account the relative priorities of the ·MAC CE for C-RNTI or data from UL-CCCH. · MAC CE for Data Volume · Power Headroom Reporting (DPR). ·MAC CE for SPS verification. ·MAC CE for BSR, excluding BSR included in padding. ·MAC CE for PHR, Enhanced PHR, or Dual Connectivity PHR. MAC for Sidelink BSR, excluding Sidelink BSR included in padding CE. ·Data from any logical channel except data from UL-CCCH. ·MAC CE for recommended bitrate query. · MAC CE for BSR included in padding. MAC CE for Sidelink BSR included in padding.

[0068] In Rel-15 NR, logical channels are ordered in the following order (first in the list has highest priority): Priorities may be assigned according to the following criteria: ·C-RNTI MAC Data from CE or UL-CCCH. · Configured Grant Verification MAC CE. ·MAC CE for BSR, excluding BSR included in padding. Single-entity PHR MAC CE or multi-entity PHR MAC CE. ·Data from any logical channel except data from UL-CCCH. · MAC CE for BSR included in padding.

[0069] In this description, we will be referring to non-padding BSRs, BSRs, and In this description, we will also exclude the BSR included in the padding. Non-padding sidelink BSR, MAC CE for sidelink BSR In Rel-15 LTE, non-padding BSR is used for non-padding sidelinks. This non-padding sidelink BSR takes precedence over the UL-CCCH BSR. It has priority over data from any logical channel except for Rel- In 15 NR, the non-padding BSR is used for all data except data from the UL-CCCH. This takes priority over data from the physical channel.

[0070] The above prioritization rules determine the relative priority between sidelink and uplink transmissions. For example, the UL data that triggers the BSR does not take into account the sidelink BSR. The BSR will not send sidelink data even if it has a lower priority than the sidelink data that triggers the Always takes priority over Drink BSR.

[0071] As mentioned above, the term "BSR" refers to the UL buffer associated with the MAC entity. The serving eNB (in the case of LTE) provides information about the amount of data available for transmission within the or gNB (in the case of NR), On the other hand, the "Sidelink BSR" is a sidelink BSR associated with a MAC entity. The serving eN then transmits information about the amount of sidelink data available for transmission in the buffer. It may refer to the procedure used to provide B.

[0072] Rules for prioritizing sidelink vs. UL data transmissions are also needed. In the current LTE V2X (e.g., TS 36.321), if the following conditions are met, the V2X cycle is Drink communication transmissions are prioritized over uplink transmissions. (1) When transmitting, the MAC entity performs uplink transmission and V2X sidelink communication. When it is not possible to simultaneously send and receive messages. (2) When uplink transmission is not prioritized by higher layers. (3) The highest priority value of the sidelink logical channel in the MAC PDU is If the link transmit prioritization threshold (thresSL-TxPrioritization) is configured, this value If it is less than.

[0073] In the LTE V2X standard, if the following conditions are met in accordance with the above conditions, Sidelink transmissions have priority over sidelink transmissions. (1) When transmitting, the MAC entity performs uplink transmission and V2X sidelink communication. When it is not possible to simultaneously send and receive messages. (2) When uplink transmission is not prioritized by higher layers, e.g., when the UE is not receiving an urgent When PDN connection is established, the UE transmits V2X communication through PC5 to the lower layers. may send an indication to prioritize transmission over the urgent PDN connection. (e.g. TS 24.386). (3) The highest priority value of the sidelink logical channel in the MAC PDU is If the link transmit prioritization threshold (thresSL-TxPrioritization) is configured, this value is greater than or equal to.

[0074] As mentioned above, the NR system will provide enhanced mobile services over the Uu interface. In addition to enhanced Mobile Broadband (eMBB) and massive Machine Type Telecommunications (mMTC) In addition, it supports a diverse set of services, including Ultra-Reliable Low-Latency Services (URLLC). Basic safety services, as well as vehicle platooning, extended sensors, advanced driving, The latest technology is expected to support various degrees of URLLC services, such as remote driving. V2X is a technology that provides information and entertainment over sidelinks, including sidelinks by relay UE nodes. entertainment services and other time-sensitive critical services. Furthermore, sidelink or uplink transmissions are also expected to be It may be based on free resource allocation, where the UE autonomously chooses the resources for transmission. In light of these NR requirements and these latest V2X requirements, in addition to emergency calls, Some uplink transmissions are more critical and time-sensitive than some V2X communications. While other V2X transmissions are critical and uplink transmissions For example, in the case of relay UE nodes, some non- Emergency uplink transmissions are more critical and time-sensitive than sidelink transmissions. Therefore, the absolute priority configured for sidelink transmissions LTE V2X with sidelink transmissions prioritized over uplink transmissions based on a ranking threshold The prioritization approach may not be suitable regardless of the priority of the uplink transmission. Therefore, new prioritization rules are introduced between sidelink and uplink transmissions. It is needed.

[0075] In conventional systems, sidelink transmission opportunities are periodic with fixed transmission time intervals and fixed NR sidelink transmissions follow a fixed transmission duration. NR sidelink transmissions do not have a predetermined periodicity of transmission opportunities. In the case of an NR RAT design with variable transmission time intervals and variable transmission time lengths, As a result, multiple overlapping sidelink grants (e.g., sidelink transmissions) may occur. Similarly, multiple uplink grants may coexist within a UE. grants for uplink transmissions also coexist within the UE. The rules for prioritizing sidelink transmissions relative to link transmissions need to be expanded. do.

The method also includes determining a priority for transmission of a drink communication. To prioritize V2X sidelink transmissions, sidelink PPPR or The method also includes using uplink PPPR when grants overlap. The method includes determining the priority of V2X sidelink transmissions relative to V2X sidelink transmissions.

[0085] Another solution described herein is to provide a method for determining transmission parameters associated with a radio resource grant. A method for determining the meter is included.

[0086] In support of the NR V2X solution described herein, the NR V2X MO is configured In addition to the configuration parameters, the following V2X configuration parameters are included in the LTE V2X MO: There is. Prioritized Bit Rate (PBR) for each allowed V2X service. · Bucket size length (BSD) per allowed V2X service. A list of allowed SCSs for each permitted V2X service. List of allowed V2X BWPs for each allowed V2X service. List of allowed RATs for each permitted V2X service. A list of allowed RAT versions for each permitted V2X service. A list of allowed transmission profiles for each allowed V2X service. A list of allowed carrier frequencies for each permitted V2X service.

For example, the number of paths may be 2, 3, or 4. , or even more.

[0087] NR V2X MO is based on the transmission mode (unicast, groupcast or broadcast). cast) and V2X services, e.g., PSID or ITS for V2X applications. -AID and mapping may be included. For example, the transmission mode may be For V2X services for which no transmission mode mapping is configured, a default One or more default transmission modes may be configured for V2X Mapping of transmission modes to V2X services may be configured per service. This is achieved by using a structure within the NR V2X MO that clearly associates X services with transmission modes. Alternatively, the association may be implicit and may be achieved by broadcast transmission. Layer 2 of V2X services and destinations for ,groupcast transmission, and unicast transmission The mapping to the ID is done using a separate or dedicated Information Element (IE ) or data structure. Mapping of transmission modes to V2X services defines the mapping between transmission modes and service data flows or packet filter sets. For example, the mapping between transmission modes and V2X services may include: Several mappings including transmission modes and service data flows or packet filter sets In an alternative embodiment, a mapping between transmission modes and V2X services may be implemented. For each V2X service, the mapping between the V2X service and multiple transmission modes is performed. For example, the association between the V2X service and the transmission mode may include, for each service, For example, a PSID or ITS-AID may be associated with multiple transmission modes. This is done at a service level.

[0088] NR V2X MO uses PC5 QoS Identifier (PQI) and V For example, the PQI may include a mapping to a permitted V2X service. It may be configured per V2X service. One or more default PQIs may be configured for use by the V2X service. A PQI may contain multiple service data flows or packet filter sets. The mapping between PQI and V2X service is performed by using PQI and service data flow or packet flow. For example, a mapping between PQI and V2X services. The mapping is based on the PQI and service data flow or packet filter set. In an alternative embodiment, the PQI and V2X service Mapping between V2X service and multiple PQIs is performed for each V2X service. For example, the association between the V2X service and the PQI may be If a service (e.g., PSID or ITS-AID) is associated with multiple transmission modes, It is generated at a service level where there is a possibility of

[0089] The NR V2X MO determines the transmission range and the V2X service (e.g. PSID or ITS-AID), e.g., groupcast or unicast The transmission range may be configured for each V2X service. For V2X services for which no range mapping is configured, a default transmission range is configured. The default transmission range may be, for example, In this case, it may be configured for each V2X service. Mapping of transmission ranges to V2X services contains a mapping between transmission ranges and service data flows or packet filter sets. For example, the mapping between transmission ranges and V2X services may be Several mappings including ranges and service data flows or packet filter sets In an alternative embodiment, the mapping between transmission ranges and V2X services may include V Each V2X service may contain a mapping between the V2X service and multiple transmission ranges. For example, the association between V2X services and transmission ranges is determined by the respective services (e.g., PS A service where a single ITS-ID (or ITS-AID) may be associated with multiple transmission ranges. Mapping of transmission ranges to V2X services and transmission modes and V2X services are jointly generated using the same IE or data structure. It is okay to do so.

[0090] NR V2X MO also considers each QoS rule as a QFI for the associated QoS flow, Contains a list of allowed PC5 QoS rules, including the default filter set and priority value. That's fine too.

[0091] NR V2X MO also includes mapping between QFI (QoS flow identifier) and PQI, Mapping between PQI and logical channel, mapping between QFI and sidelink bearer, Q OS characteristics, e.g., mapping PQI to QoS profile or resource allocation Mapping between resource allocation modes and logical channels, or resource allocation modes and QoS flows As used herein, the term "QFI" may also refer to a mapping between PC5 and It is sometimes called a QoS Flow Identifier (PC5 QoS Flow Identifier: PFI) .

In this case, the latter may be the UE-V2X provisioning configuration parameter validity type. The validity timer may be checked (step 1412), and if the validity timer expires, V A configuration parameter request to the 2X control function 1404 may be triggered (step 1413) Similarly, if the UE goes out of coverage, e.g., while the UE is out of coverage, If the configuration parameter validity timer expires, the UE-V2X function 1402 You may need to be aware of this to avoid unnecessarily triggering configuration requests to the network. In step 1414, the V2X control function 1404 V2X configuration parameters are programmed to the UE-V2X function 1402 through the NR interface. In step 1415, the UE RRC 1401 and the UE-V 2 function 1402 stores new V2X configuration parameters or updates stored V2X configuration parameters.

[0143] When a new transmission is to be performed, the MAC entity Only the following rules may be assigned resources:

[0144] For the selection of the V2X transmission destination as part of the logical channel selection procedure, the term " The "selected sidelink logical channel" is, as mentioned above, e.g., a sidelink resource graph. regarding the selected sidelink logical channels that are allowed to function by the This may be used as a mapping for the sidelink resource grants mentioned above. It may include a sidelink logical channel that implements ping constraints.

[0145] Another embodiment of destination selection is described herein, which is described herein. The first transmission destination selection method may be used in combination with any of the embodiments. The entity may, when a new transmission is made, specify the ProSe destination, e.g. From the selected sidelink logical channels with available data, the highest priority selected sidelink logical channel is selected. A send destination having a link logical channel may be selected. With the same destination ID and data available for transmission, as defined in the channel selection solution. Each selected sidelink logical channel is multiplexed and assembled within one PDU. It is okay to do so.

[0146] If the UE supports multiple transmit chains, the UE can transmit to multiple destinations simultaneously. The UE may select the ProSe destinations, one per transmission chain, in descending order of the priority of the transmission destinations. Select one ProSe destination. The priority of a transmission destination is determined by the selected logical channel of that destination. the selected sidelink logic having the highest priority and available data for transmission. The priority of the channel. The destination selected by the destination selection procedure is called the "selected destination." This may be referred to herein as "destination."

[0147] FIG. 17 shows a V2X transmission destination selection procedure 1700 for a single transmit chain. In step 1710, logical channel selection may be performed on the grant allocation. At 1711, selecting from among available V2X transmission destinations having data available for transmission. A V2X transmission destination having a logical channel may be selected.

[0148] FIG. 18 illustrates a V2X transmission destination selection procedure 1800 for multiple transmit chains. In step 1810, logical channel selection may be performed on the grant allocation. 1811, selecting from among available V2X transmission destinations having data available for transmission; A V2X transmission destination having a logical channel may be selected. Step 181: The X transmission destination may be removed from the set of available V2X transmission destinations. In 3, it may be determined whether there are more available transmit chains, and If there is a possible transmit chain, step 1811 is repeated.

[0149] Transmission modes may include broadcast, groupcast or unicast. The transmission mode priority may be (pre-)configured or defined in the UE. For example, a broadcast transmission may have a higher priority than a groupcast transmission. Often, this groupcast transmission may have a higher priority than unicast transmission. be.

[0150] In the alternative transmission destination selection method, the MAC entity selects the ProSe destination, e.g., a selected sidelink logical channel with data available for transmission and selects a transmission destination from among the selected sidelink logical channels that has the highest priority. In the case of a tie, for example, multiple transmission destinations may choose the highest priority destination with data available for transmission. If it has a preferred selected logical channel, the UE shall select the transmission destination according to one of the following: You may choose.

[0151] The destination among the tie-up destinations that has the highest transmission mode priority and is available for transmission. Among the selected logical channels having data, the logical channel with the highest selection priority is In other words, the destination with the highest transmission mode priority and the highest transmission mode priority among the tie-up destinations. The selected logical channel having the data is identified. The transmission destination is then determined based on the most recent transmission mode. The highest priority logical channel among those determined to have available data transmission. It may be selected as the destination corresponding to the logical channel.

[0152] Among the tied-up destinations, the destination with the higher transmission mode priority is the one that is available for transmission. The destination with the highest selected priority logical channel that has data. Among the tie-up destinations, the selected destination is the selected highest priority destination with data available for transmission. The higher priority channel is the one with the higher transmission mode.

[0153] The term "selected logical channel" refers to the channel selected by the sidelink resource grant, as described above. Used for selected sidelink logical channels that are allowed to function This may be achieved by implementing the mapping constraints for sidelink resource grants mentioned above. It may include the sidelink logical channels that can be implemented.

[0154] In another alternative transmission destination selection method, the UE selects the destination with the highest transmission mode priority and available for transmission. The logical channel mapping scheme for the resource grants described above is also included. In case of a tie, the UE may select a transmission destination with a logical channel that satisfies the following conditions: You may select among the tie-up sending destinations according to one of the following:

[0155] The highest transmission mode priority, has data available for transmission, and has the resources mentioned above. The highest priority logical channel that implements the logical channel to grant mapping constraints. Destination with a rule.

[0156] of logical channels that have data available for transmission and for which the resource grants are mentioned above The destination with the highest priority logical channel that can fulfill the mapping constraints.

[0157] In yet another alternative transmission destination selection method, the UE selects the transmission mode with the highest transmission mode priority and has data available for the resource grants and has the above-mentioned mapping of logical channels to resource grants. The transmission destination may be selected to have the highest priority logical channel that can fulfill the routing constraints.

[0158] One or more of the alternative procedures may be used to link between sidelink LCP procedures. It may be used for source allocation.

[0159] FIG. 19 illustrates an example during an NR V2X sidelink LCP procedure according to one embodiment. 19 shows an exemplary resource allocation procedure 1900, which is implemented as described herein. The entity may use the When the resource allocation is completed, the resource may be allocated based on the procedure 1900.

[0160] In step 1910, it may be determined whether there is a resource grant available. In step 1911, the selected sidelink logical channel (LCHj with Bj>0 of the selected destination) may be assigned resources in descending order of priority, with the selected logical channel and the selected destination The logical channel selection solution and the destination selection solution described herein are respectively The PBR of the selected logical channel of the selected destination is set to "infinite". If so, the MAC entity shall select the selected sidelink logical channel with lower priority. Before satisfying the PBR, all data available for transmission on the selected sidelink logical channel shall be In step 1912, Bj may allocate resources according to the above side link theory. The number may be decremented by the total size of the MAC SDUs provided to the physical channel j.

[0161] In step 1913, it may be determined whether there is a resource grant available. In step 1914, if there are any remaining resource grants, the data for that logical channel is All selected cycles of the selected destination are continued until either the selected or sidelink grants are exhausted first.

[0164] A solution for uplink data logical channel prioritization according to another embodiment is As described herein, this may be combined with any of the embodiments described herein. This solution may be used in conjunction with the NR uplink data logical channel prioritization procedure. Logical channel prioritization procedures over the NR Uu interface Regarding the impact of sidelink related transmissions on the UE.

[0165] In Rel-15 LTE, the non-padding BSR is a non-padding sidelink BSR. This non-padding sidelink BSR takes precedence over the data from the UL-CCCH. It takes priority over data from any logical channel except Rel-15 N. In R, the non-padding BSR is used for all logical channels except for data from the UL-CCCH. For NR V2X deployments, the sidelink BSR The prioritization of non-padding BSR for uplink and sidelink transmissions is The same priority order may be followed between the two, e.g., sidelink transmissions take priority over uplink transmissions. If preceded by a BSR, the corresponding sidelink BSR takes precedence over the corresponding uplink transmit BSR. In particular, a non-padding V2X sidelink BSR is allowed if the following conditions are met: If so, it may take precedence over a non-padding BSR. (1) UL data related to BSR is transmitted by higher layers to the sidelink BSR. does not take priority over the Sidelink data being transmitted. (2) Sidelink logical channel for sidelink data involved in sidelink BSR The highest priority value of the channel is the sidelink transmission prioritization threshold (thresSL-TxPrioritiza tion) is configured to be less than this value.

[0166] The second of the above conditions is that non-emergency uplinks are allowed regardless of the priority of uplink communications. Absolute V2X sidelink threshold for prioritizing sidelink communications over V2X communications As mentioned above, this condition is based on the NR V2X sideband for uplink transmissions. Therefore, according to one embodiment, The priority of uplink transmission is given to V2X sidelink transmission, which has a higher priority than uplink transmission. It may also be used to rank items. Therefore, an alternative example to the second condition above is may include the following:

[0167] (1) Sidelink logical channel for sidelink data involved in sidelink BSR The highest priority value of a channel is the highest priority of a logical channel for UL data involved in BSR. If it is less than the rank value.

[0168] (2) Sidelink logical channel for sidelink data involved in sidelink BSR The highest priority value of the channel is the sidelink transmission prioritization threshold (thresSL-TxPrioritiza If the Sidelink BSR is configured, the value must be less than this value and the The highest priority value of the sidelink logical channel for sidelink data that is If it is less than the highest priority value of the involved UL data-oriented logical channel. The threshold parameter (thresSL-TxPrioritization) determines whether SL V2X transmissions are uplink transmissions. In the case of overlapping time periods, this is used to determine whether the former should be given higher priority than the latter. It may be pre-configured in the UE or may be configured specifically for RRC. signaling, RRC common signaling, e.g., RRC broadcast signaling It may be configured in the UE through a

[0169] (3) Sidelink logical channel for sidelink data involved in sidelink BSR The highest priority value of the channel is the sidelink transmission prioritization threshold (thresSL-TxPrioritiza If the UL data involved in the BSR is smaller than this value, The highest priority value of the logical channel for If sUL-TxPriortization) is configured, it is greater than this value. The parameter thresUL-TxPrioritization determines the time at which UL transmissions overlap with sidelink communications. If so, indicates the threshold used to determine whether the former should be given lower priority than the latter. It may be pre-configured in the UE or used for RRC dedicated signaling. , through RRC common signaling, e.g., RRC broadcast signaling, It may be configured as follows.

[0170] (4) Sidelink logical channel for sidelink data involved in sidelink BSR The highest priority value of the channel is the sidelink transmission prioritization threshold (thresSL-TxPrioritiza If the UL data involved in the BSR is smaller than this value, The highest priority value of the logical channel for If sUL-TxPriortization is configured, it must be greater than this value and the side link Highest priority of sidelink logical channel for sidelink data involved in BSR The value of this parameter is less than the highest priority value of the logical channel for UL data involved in the BSR. If so.

[0171] Another embodiment of the present invention provides a method for prioritizing sidelink data relative to uplink data. A solution for this is described herein, which may be implemented in any of the embodiments described herein. As mentioned above, in conventional LTE V2X, If the conditions are met, V2X sidelink transmissions will have priority over uplink transmissions. . (1) When transmitting, the MAC entity performs uplink transmission and V2X sidelink communication. When it is not possible to simultaneously send and receive messages. (2) When uplink transmission is not prioritized by higher layers. (3) The highest priority value of the sidelink logical channel in the MAC PDU is If the link transmit prioritization threshold (thresSL-TxPrioritization) is configured, this value If it is less than.

[0172] The third of the above three conditions is that non-urgent uplinks are allowed regardless of the priority of the uplink communications. Absolute V2X sidelink for prioritizing sidelink communications over V2X sidelink communications As mentioned above, this third condition is the NR V It may not be sufficient to prioritize 2X sidelink communications. Depending on the state, the priority of the uplink transmission is subject to a third condition with one of the following alternatives: By replacing the V2X sidelink transmission with the V2X uplink transmission, the V2X sidelink transmission is prioritized over the uplink transmission. It may be used when

[0173] (1) The priority value of the V2X sidelink transmission is smaller than the priority value of the uplink transmission. This criterion is used for all sidelink transmission modes and , may be used especially in the case of unicast transmissions, for example.

[0174] (2) The priority value of V2X sidelink transmission is equal to the sidelink transmission prioritization threshold ( If thresSL-TxPrioritization is configured, it must be less than this value and V2X If the priority value of the sidelink transmission is less than the priority value of the uplink transmission. The priority threshold parameter thresSL-TxPrioritization determines whether SL V2X transmissions are uplink transmissions. In the case of overlapping time periods, this is used to determine whether the former should be given higher priority than the latter. It may be pre-configured in the UE or may be configured specifically for RRC. signaling, RRC common signaling, e.g., RRC broadcast signaling This criterion is used for all sidelink transmission modes. At the same time, this standard is specific to broadcast or groupcast transmissions. may be used for.

[0175] (3) The priority value of V2X sidelink communication is equal to the sidelink transmission prioritization threshold ( If thresSL-TxPrioritization is configured, it must be less than this value and The priority value of the uplink transmission is equal to or greater than the uplink transmission prioritization lower threshold (thresUL-TxPriortizat If the priority threshold parameter thresUL is configured, it is greater than this value. -TxPrioritization: When UL transmission overlaps in time with sidelink communication, the former is prioritized. When used to indicate the threshold used to determine whether a This may be pre-configured in the UE or may be implemented using RRC dedicated signaling, RRC shared signaling, etc. Nulling, e.g., configured in the UE through RRC broadcast signaling This criterion is used for all sidelink transmission modes and also applies to: It may be particularly used for broadcast or groupcast transmissions.

[0176] (4) The priority value of V2X sidelink transmission is equal to the sidelink transmission prioritization threshold ( If thresSL-TxPrioritization is configured, it must be less than this value and The priority value of the uplink transmission is equal to or greater than the uplink transmission prioritization lower threshold (thresUL-TxPriortizat ion) is configured, it must be greater than this value and the V2X sidelink transmission priority The priority value is less than the priority value of the uplink transmission. This criterion is applied to all sidelinks. This criterion is used for broadcast transmission or group transmission as well as for group transmission mode. It may be particularly useful for broadcast transmission.

[0177] In the above, the priority value of the V2X sidelink transmission is set to the sidelink priority in the MAC PDU. It may be the highest priority value of the logical channel. Similarly, the priority value of the uplink transmission may be the highest priority value of an uplink logical channel in a MAC PDU. The lower the priority value of a logical channel, the higher the priority of the logical channel may be. Similarly, the lower the priority value of a transmission, the higher the priority of the transmission may be.

[0178] (5) The highest priority value of the sidelink logical channel in the MAC PDU is If the link transmit prioritization threshold (thresSL-TxPrioritization) is configured, this value In this case, the parameter thresSL-TxPrioritization is set to Specific to each transmission destination, specific to each transmission mode, or specific to each sidelink transmission destination and transmission mode The V2X sidelink transmissions relative to the uplink transmissions may be (pre-)configured in the specific UE. When determining the priority, V2X sidelink transmission PPPR or uplink transmission PPP R may also be taken into account by the UE. Similarly, V2X support for uplink transmissions When prioritizing link transmissions, if one transmission is preferred over another The amount of radio resources at risk of being lost may be taken into account by the UE. ,The third condition above may be modified as follows:

[0179] (1) The priority value of the V2X sidelink transmission is smaller than the priority value of the uplink transmission. If the priorities are equal, V2X sidelink communication will be based on the PPPR value of the uplink. It may be prioritized if it is greater than the PPPR value of the link transmission, or if it has equal priority. In this case, the amount of resource grant for V2X sidelink communication is This criterion applies to all sidelinks. While this criterion is used for the network transmission mode, it is also used in the case of unicast transmission, e.g. It may be used in particular.

[0180] (2) The priority value of V2X sidelink transmission is equal to the sidelink transmission prioritization threshold ( If thresSL-TxPrioritization is configured, it must be less than this value and V2X If the priority value of the sidelink transmission is less than the priority value of the uplink transmission. V2 X If the priority between the sidelink communication priority and the uplink transmission priority is equal, V2X sidelink communication has a PPPR value that is greater than the PPPR value of uplink transmission. Alternatively, if the priorities are equal, the V2X sidelink communication , the amount of resource grant for that transmission is greater than the amount of resource grant for uplink transmission. This criterion is the same as that used for all sidelink transmission modes. Sometimes this standard is used specifically for broadcast or groupcast transmissions. good.

[0181] (3) The priority value of V2X sidelink transmission is equal to the sidelink transmission prioritization threshold ( If thresSL-TxPrioritization is configured, it must be less than this value and The priority value of the uplink transmission is equal to or greater than the uplink transmission prioritization lower threshold (thresUL-TxPriortizat ion) is configured, it must be greater than this value and the V2X sidelink transmission priority If the priority value is smaller than the priority value of the uplink transmission, V2X sidelink communication priority is If the priority between the V2X sidelink communication and the uplink transmission priority is equal, A transmission should be prioritized if its PPPR value is greater than the PPPR value of the uplink transmission. If the priority is equal, the V2X sidelink communication will If the amount of source grant is greater than the amount of resource transmission for uplink transmission, it is prioritized. This criterion is used for all sidelink transmission modes and also applies to It may be particularly used for broadcast or groupcast transmissions.

[0182] In the above, the PPPR value for V2X sidelink transmission is the sidelink The maximum PPPR value of the logical channel is given by , the largest PPPR value of the uplink logical channels in the MAC PDU. The higher the PPPR value of the channel, the higher the reliability requirement for the logical channel may be. Similarly, the higher the PPPR value of a transmission, the higher the reliability requirements for the transmission may be.

[0183] As noted above in light of the embodiments described herein with respect to UL LCP, BSRs other than the BSR included in the padding and Sidelink BSRs included in the padding The sidelink BSR, excluding the UL-CCCH, also transmits data from any logical channel, excluding the UL-CCCH. It may take priority over data from other channels. Sidelink BSR prioritization,BSR prioritization for sidelink transmissions The prioritization algorithm described in the embodiments described herein for the UL LCP The approach is to prioritize the relative priority between the UL data involved in the BSR and the sidelink data. Similarly, the sidelink BS for UL data transmission may R prioritization is performed to distinguish between sidelink data involved in sidelink BSR and UL data. The relative prioritization between the

[0184] The non-padding V2X sidelink BSR is based on UL data if the following conditions are met: may also be given priority. (1) When transmitting, the MAC entity performs uplink transmission and V2X sidelink communication. When it is not possible to simultaneously send and receive messages. (2) UL data is sent by higher layers to the sidelink device involved in the sidelink BSR. If it does not take precedence over the data. (3) Sidelink logical channel for sidelink data involved in sidelink BSR The highest priority value of the channel is the sidelink transmission prioritization threshold (thresSL-TxPrioritiza tion) is configured to be less than this value.

[0185] Examples of alternatives to the third condition above may include:

[0186] (1) Sidelink logical channel for sidelink data involved in sidelink BSR The highest priority value of a logical channel in the UL MAC PDU is the highest priority value of a logical channel in the UL MAC PDU. This criterion is used for all sidelink transmission modes, e.g. For example, the highest priority sidelink for sidelink data involved in the sidelink BSR. This criterion may be used in particular when the link logical channel supports unicast transmission. .

[0187] (2) Sidelink logical channel for sidelink data involved in sidelink BSR The highest priority value of the channel is the sidelink transmission prioritization threshold (thresSL-TxPrioritiza If the Sidelink BSR is configured, the value must be less than this value and the The highest priority value of the sidelink logical channel for sidelink data in the UL M If the value is less than the highest priority of any logical channel in the AC PDU, the priority threshold parameter The meter thresSL-TxPrioritization is used to determine whether SL V2X transmissions overlap in time with uplink transmissions. If so, indicate the threshold used to determine whether the former should be given higher priority than the latter. It may be pre-configured in the UE or used for RRC dedicated signalling. RRC common signaling, e.g., RRC broadcast signaling This criterion is the same as that used for all sidelink transmission modes. Sometimes, for example, the highest priority for sidelink data involved in the sidelink BSR. If the sidelink logical channel supports groupcast or broadcast transmissions, In this case, this criterion may be particularly useful.

The threshold UL-TxPrioritization is used when UL transmissions overlap in time with sidelink communications. Used to indicate the threshold used to determine whether the former should be given lower priority than the latter. It may be pre-configured in the UE or transmitted via RRC dedicated signaling, RRC Common signaling, e.g., configured in the UE through RRC broadcast signaling This criterion is used for all sidelink transmission modes and may be used for For example, the highest priority sidelink for sidelink data involved in the sidelink BSR. This is used when the logical channel supports groupcast or broadcast transmission. The criteria may be used specifically.

[0189] (4) Sidelink logical channel for sidelink data involved in sidelink BSR The highest priority value of the channel is the sidelink transmission prioritization threshold (thresSL-TxPrioritiza If UL MAC PDU is configured, it must be less than this value and the logical The highest priority value of the physical channel is equal to or exceeds the uplink transmission prioritization lower threshold (thresUL-TxPr If Sidelink BSR is configured, it must be greater than this value. The highest priority value of the sidelink logical channel for sidelink data involved in If the value is smaller than the highest priority value of the logical channel in the UL MAC PDU, this criterion is used for all sidelink transmission modes and at the same time, e.g., for the sidelink BSR. The sidelink logical channel with the highest priority for the sidelink data involved is the group This criterion may be used in particular when dealing with cast or broadcast transmissions. .

[0190] (5) Sidelink logical channel for sidelink data involved in sidelink BSR The highest priority value of the channel is the sidelink transmission prioritization threshold (thresSL-TxPrioritiza If the threshold is less than this value, the parameter thresSL-Tx Prioritization can be specific to each sidelink transmission destination, specific to each transmission mode, or specific to each sidelink Drink transmission destinations and transmission modes may be specific (pre-)configured in the UE.

[0191] V2X sidelink transmissions have priority over non-padding BSRs if the following conditions are met: It is okay to do so. (1) When transmitting, the MAC entity performs uplink transmission and V2X sidelink communication. When it is not possible to simultaneously send and receive messages. (2) UL data related to BSR is prioritized by higher layers over sidelink data. If not preceded. (3) The highest priority value of the sidelink logical channel in the sidelink MAC PDU. However, the sidelink transmission prioritization threshold (thresSL-TxPrioritization) is configured. This criterion is used for all sidelink transmission modes. At the same time, this criterion may be used especially in the case of unicast transmissions, for example.

[0192] Examples of alternatives to the third condition may include:

[0193] (1) The highest priority value of the sidelink logical channel in the sidelink MAC PDU. is less than the highest priority value of the logical channel for UL data involved in the BSR. This criterion is used for all sidelink transmission modes, and at the same time, this criterion is For example, it may be used especially in the case of unicast transmission.

[0194] (2) The highest priority value of the sidelink logical channel in the sidelink MAC PDU. However, the sidelink transmission prioritization threshold (thresSL-TxPrioritization) is configured. When the Sidelink MAC PDU is The highest priority value of a channel is the highest priority of a logical channel for UL data involved in BSR. The priority threshold parameter thresSL-TxPrioritization is set to S L When V2X transmissions overlap in time with uplink transmissions, the former should be given priority over the latter. It may be used to indicate the threshold used to determine whether to increase Pre-configured in the UE or RRC dedicated signaling, RRC common signaling, e.g. This may be configured to the UE through RRC broadcast signaling. This criterion is used for all sidelink transmission modes as well as for broadcast transmission. It may be particularly used for broadcast or groupcast transmissions.

[0195] (3) The highest priority value of the sidelink logical channel in the sidelink MAC PDU. However, the sidelink transmission prioritization threshold (thresSL-TxPrioritization) is configured. When the maximum logical channel for UL data involved in BSR is less than this value, The high priority value is the uplink transmission prioritization lower threshold (thresUL-TxPriortization). If configured, the priority threshold parameter thresUL-TxPr is greater than this value. Prioritization is when UL transmissions overlap in time with sidelink communications, and the former takes priority. It is sometimes used to indicate the threshold used to determine whether the It can be pre-configured in the UE or can be implemented using RRC dedicated signaling, RRC common signaling, etc. may be configured in the UE via RRC broadcast signaling, for example. This criterion is used for all sidelink transmission modes, and also applies to broadcast It may be particularly used for broadcast or groupcast transmissions.

[0196] (4) The highest priority value of the sidelink logical channel in the sidelink MAC PDU. However, the sidelink transmission prioritization threshold (thresSL-TxPrioritization) is configured.

[0197] Prioritization solutions for sidelink transmissions relative to uplink transmissions described herein where the parameter thresSL-TxPrioritization may be (pre-)configured in the UE, and Specific to each sidelink transmission destination, specific to each transmission mode, or specific to each sidelink transmission destination and Such configuration signaling may be specific to the Uu RR. C signaling, PC5-RRC signaling, or PC3-S signaling This may be done.

[0198] Priority, one of the QoS features, is the priority of sidelink transmissions over uplink transmissions. While used in ranking, any other QoS characteristic may be used instead of or in preference to priority. For example, in the prioritization method described above, Sidelink transmission when the link transmission QoS requires higher prioritization than UL transmission Priority replaces any other QoS criteria, so that UL transmissions take priority over UL transmissions. Similarly, the logical channel for data involved in sidelink BSR may be Non-padding side if the UL requires higher priority than the UL BSR. Sidelink BSRs, such as link BSRs, have priority over UL transmissions, including UL BSRs. An example of a QoS feature that may be used in the prioritization method described above is priority Instead, delay, range, a combination of priority and delay and range, or PQI (PC5 Any other single metric that may be used to represent QoS, such as a QoS identifier. It's okay to have one.

[0199] Examples of different overlapping grant scenarios are shown in Figures 7, 8, 9, 10 and 11. do.

[0200] Figure 7 shows that both grants overlap completely and the first allowed transmission start point is the same. Similarly, Figure 8 shows the case where the two grants have completely overlapping time lengths. The grants are the same, and the last allowed transmission end point is the same, but the duration of the two grants is different. Figures 9 and 10 show the case where the grants have different durations and overlap partially. , the first allowable transmission start point and the last allowable transmission end point of each grant are different. Figure 11 shows that the grants have different durations, completely overlap, and the maximum duration of each grant is This shows a case where the first allowable transmission start point and the last allowable transmission end point are different.

[0201] In LTE V2X, the priority of uplink transmission is higher than that of the above-mentioned side link. The first condition for prioritizing upstream link communications is that the MAC entity must "When V2X sidelink communication transmission and V2X sidelink communication transmission cannot be performed simultaneously." The sentence "at the time of sending" is unclear and is not clear enough in the context of overlapping grants. Therefore, the condition "The MAC entity is "When V2X sidelink transmission and V2X sidelink communication transmission cannot be performed simultaneously," UE behavior needs to be clarified, updated or extended to avoid ambiguity. For example, if a transmission is in progress on the uplink, then a subsequent transmission may occur on the sidelink. Considering a scenario triggered by a traffic jam, the existing LTE V2X transmission prioritization rules are In this scenario, the sidelink transmission may be prioritized over the ongoing uplink. how uplink transmissions are handled (e.g., whether interruption or abandonment of uplink transmissions may be implemented) Therefore, it is not clear whether V2X sidelink transmissions are prioritized over uplink transmissions. The first of the three preceding LTE V2X conditions is extended with one of the following conditions: It is okay to do so.

[0202] (1) When transmitting, the MAC entity performs uplink transmission and V2X sidelink communication. The prioritization is performed when the uplink transmission cannot be performed simultaneously with the uplink transmission. It is not possible to forcibly discard uplink TBs that have already been sent to lower layers for transmission during this period. No. The prioritization rules in the LTE V2X regulations make it impractical or An example of a scenario where an uplink transmission may be forced to be discarded if it is not feasible is shown in Fig. 8, the scenario of sidelink and uplink transmission overlap as shown in Figs. 10 and 11. It could be Rio.

[0203] Alternatively, the fourth condition for prioritizing V2X sidelink transmission over uplink transmission is: It could be something like the below.

[0204] (1) The prioritization is based on the packets already sent to lower layers for transmission in this uplink transmission period. It is not possible to forcibly discard a received uplink TB.

[0205] Regarding random access transmission, the priority of sidelink transmission is given to random access. If the triggering event is higher than the sidelink transmission, e.g., random access, For example, it may be given priority over random access message 1 transmission. UL data during RRC_CONNECTED when there are no available PUCCH resources The arrival of the UL data triggers random access, but the UL data arrives at the side link. If the sidelink transmission has a lower priority than the random access, the sidelink transmission will take precedence over the random access. It needs to be prioritized.

[0206] The determination of transmission parameters associated with the radio resource grant is described herein. One issue that needs to be resolved is the scheduled grant, configured Submissions associated with resource grants, either autonomous or non-autonomous grants The question is how the MAC determines the parameters.

[0207] The determination of the allowed transmission modes associated with a radio resource grant comprises the following steps: This may occur.

[0208] The UE MAC determines the radio resource grant based on one or more of the following: The allowable transmission modes may be determined by the

[0209] A grant may also include an indication of the allowable transmission modes associated with the grant. good.

[0210] The PHY may indicate to the MAC the allowed transmission modes associated with the grant.

[0211] For example, the RRC (pre-)configures the UE with sidelink radio resources (e.g. The physical sidelink shared channel resource (e.g., physical sidelink shared channel resource) is determined by the allowed transmission modes associated with the resource. This may include side configuration, e.g., side configuration (pre-)configured in the UE by RRC. Link radio resources (e.g., physical sidelink shared channel resources) are allocated in the transmission mode Scheduled, e.g., dynamic grant or Mode 1 When a grant is allocated to a UE, the MAC is assigned to the UE to which the grant is mapped. The transmission mode of the grant is determined based on the allowed transmission modes of the configured sidelink radio resources. The user may determine the code.

[0212] For example, the sidelink resource pool (pre-configured) in the UE by RRC is: This may include the configuration of allowed transmission modes associated with the resource, e.g., by RRC. Therefore, the sidelink radio resource pool (pre-configured) in the UE is transmission mode specific. An autonomous grant or a Mode 2 grant may be selected by the UE. If so, the MAC will determine the sidelink radio resource configured for the UE to which the grant is mapped. The transmission mode of the grant may be determined based on the allowed transmission mode of the spool.

[0213] Determining the allowed transmission range associated with the radio resource grant comprises the steps of: There are cases where this happens.

[0214] The UE MAC determines the radio resource grant based on one or more of the following: The allowable transmission range may be determined by the

[0215] The grant may include an indication of the allowable transmission range associated with the grant. stomach.

[0216] The PHY may indicate to the MAC the allowable transmission range associated with the grant.

[0217] For example, the RRC (pre-)configures the UE with sidelink radio resources (e.g. A resource (e.g., a physical sidelink shared channel resource) is defined by the allowable transmission range associated with the resource. For example, side links (pre-)configured in the UE by RRC. The sidelink radio resources (e.g., physical sidelink shared channel resources) are transmission range specific. Scheduled, e.g., dynamic grant or Mode 1 grant. When a grant is assigned to a UE, the MAC is configured in the UE to which the grant is mapped. Determine the transmission range of the grant based on the allowed transmission range of the sidelink radio resource You may do so.

[0218] For example, the sidelink resource pool (pre-configured) in the UE by RRC is: This may include configuration of the allowed transmission range associated with the resource, e.g., by RRC. The sidelink radio resource pool (pre-configured in the UE) is transmission range specific. If autonomous grant or Mode 2 grant is selected by the UE, If so, the MAC will assign the sidelink radio resource configured for the UE to which the grant is mapped. The transmission range of the grant may be determined based on the allowed transmission modes of the pool.
