Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method and device for determining a logical channel priority. Background Art

[0002] The transmission of DRB (Dedicated Radio Bearer) is based on MAC (Media Access Control) layer scheduling. In the prior art, the uplink resource allocation of the base station is for a single terminal. In order to ensure fairness between different uplink logical channels of the same terminal and avoid starvation of some services, the prior art adopts the logical channel priority (LCP) mechanism based on logical channel priority and priority bit rate (PBR).

[0003] The LCP mechanism based on logical channel priority and PBR is as follows: when the terminal obtains the uplink resource authorization (ULgrant), the first round of resource allocation is performed according to the PBR for each logical channel with data transmission requirements in descending order of the logical channel priority; if there are remaining resources after the first round of resource allocation, resources are allocated to each logical channel in turn in descending order of the priority of the logical channel currently with data transmission requirements.

[0004] In the above LCP process, the data transmission priority of each logical channel is determined independently. Therefore, it is impossible to ensure the synchronization of multiple QoS Flows corresponding to the same service, such as multiple QoS Flow multimodal XR (eXtended Reality) services, during air interface transmission, which may affect the user experience.

[0077] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0078] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0079] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0080] First, the following contents are introduced:

[0081] (1) Basic process of air interface data processing;

[0082] Figure 1 It is a schematic diagram of a user plane protocol stack provided by related technologies, such as Figure 1 As shown, the 5G user plane air interface protocol layer includes the SDAP (Service Data Adaptation Protocol) layer, the PDCP (Packet Data Convergence Protocol) layer, the RLC (Radio Link Control) layer, the MAC (Media Access Control) layer and the physical layer.

[0083] When a service quality flow QoS Flow (Quality of Service) reaches SDAP, SDAP will perform mapping from QoS Flow to DRB (Dedicated Radio Bearer), and form SDAPPDU (Protocol Data Unit) after mapping. SDAP PDU is PDCP SDU (Service Data Unit). The PDCP layer performs header compression, encryption and other operations on the PDCP SDU and then submits it to the RLC layer. The RLC layer then encapsulates the RLC PDU according to the MAC layer scheduling information and submits it to MAC. MAC encapsulates the received RLC PDU into MAC PDU and then submits it to the physical layer for transmission.

[0084] Among them, the principle of SDAP executing QoS Flow to DRB mapping is as follows: since the QoS attributes of data packets in a QoS Flow are basically the same, a QoS Flow can only be mapped to one DRB.

[0085] (2) Basic concepts of XR;

[0086] The communication system introduces XR (eXtended Reality) services, which are divided into the following categories:

[0087] AR (Augmented Reality): Seamless integration of the real world and the virtual world, half real and half fake

[0088] VR (Virtual Reality): It uses devices to simulate a virtual world, which is completely fake.

[0089] MR (Mixed Reality): Contains both real physical entities and virtual information.

[0090] In the development of communication systems, extended reality (XR) services are introduced. XR services can have many user devices, such as 3D glasses, handle remote controls, etc.

[0091] There are two basic ways to connect XR services to wireless networks: Mode 1: All user devices are connected to a user equipment (UE, such as a terminal), and the XR service accesses the wireless network through the terminal. In this mode, the same terminal is required to achieve coordinated transmission of different streams in an XR service, also known as intra-UE multi-modal. Mode 2: Different user devices access the wireless network as different terminals. In this mode, multiple terminals are required to achieve coordinated transmission of different streams in an XR service, also known as inter-UE multi-modal.

[0092] Figure 2 is a schematic diagram of the structure of the XR service data frame provided in the embodiment of the present application, such as Figure 2 As shown in FIG. 1 , the same data frame can be divided into multiple packet data units (PDUs). The definition of a PDU set is as follows: one or more PDUs corresponding to the same information unit constitute a PDU set.

[0093] XR services support multi-mode. In multi-mode, multiple QoS Flows of a service are transmitted synchronously during air interface transmission (also called collaborative transmission).

[0094] In the LCP process in the related art, the data transmission priority of each logical channel is determined independently, and the transmission between different LCHs (Logical Chanels, downlink logical channels) has no correlation and will not be synchronized.

[0095] The embodiments of the present application provide a method and device for determining the priority of a logical channel, so as to enable different QoS Flows corresponding to the same service to be transmitted synchronously during air interface transmission, so as to meet the requirements of multimodal services for synchronous transmission.

[0096] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0097] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems, especially 5G systems. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system, etc. These various systems include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0098] Figure 3 is one of the flow charts of the method for determining the priority of a logical channel provided in an embodiment of the present application, such as Figure 3 As shown, the method for determining the priority of a logical channel is applied to a communication device, that is, the execution subject of the method for determining the priority of a logical channel is a communication device, such as a terminal or a first network device, and the method for determining the priority of a logical channel includes the following steps:

[0099] Step 300, determining that a plurality of associated logical channels belonging to one or more terminals correspond to the same logical channel priority;

[0100] The communication device includes a first network device, which includes a network device that provides services for at least one of the one or more terminals; or the communication device includes at least one of the one or more terminals; the logical channel includes a logical channel of a Uu interface or a logical channel of a direct communication interface.

[0101] Optionally, multiple logical channels correspond to the same logical channel priority, which may mean that the multiple logical channels correspond to the same logical channel priority on the Uu interface or the direct communication interface.

[0102] Specifically, in order to coordinate the transmission between different LCHs and meet the synchronization requirements of multiple QoS Flows of user terminals during air interface transmission, the association relationship between different logical channels of one or more terminals can be determined, and the logical channels with associated relationships can be determined to use the same logical channel priority on the Uu interface or direct communication interface.

[0103] In an embodiment of the present application, the same logical channel priority corresponding to multiple associated logical channels can be determined by at least one terminal among one or more terminals to which the multiple associated logical channels belong, or by a first network device that provides services to any one of the one or more terminals.

[0104] Optionally, the first network device may be a base station or a CU (Central Unit) or a DU (Distributed Unit) or the like.

[0105] Optionally, if the same logical channel priority corresponds to multiple associated logical channels, it is determined by a first network device that provides services for any one of the one or more terminals. Specifically, how to determine the same priority may depend on the implementation of the first network device.

[0106] This application proposes a method for determining logical channel priority for services with synchronization requirements, such as XR services. This method can ensure the equality of one or more terminals transmitting the same multimodal service when obtaining air interface resources as much as possible, and better ensure that multiple streams can be transmitted synchronously on the air interface, so that the service will not be starved due to the low priority of one of the logical channels, thereby affecting the overall service performance.

[0107] The method for determining the logical channel priority provided in the embodiment of the present application determines that multiple logical channels with an associated relationship belonging to one or more terminals use the same logical channel priority, so as to achieve synchronous transmission of different QoS Flows corresponding to the same service during air interface transmission, thereby meeting the requirements of multimodal services for synchronous transmission.

[0131] Optionally, in the terminal identifier and / or logical channel identifier included in the first identifier, the terminal identifier may be a unique identifier corresponding to each terminal, such as S-TMSI (Short-Temporary Mobile Subscriber Identity) or C-RNTI (Cell-Radio Network Temporary Identity), and the logical channel identifier uniquely identifies a logical channel within a terminal. The logical channel identifiers used by logical channels corresponding to different terminals may be the same or different.

[0132] Specifically, the second network device may directly inform the first network device of the association relationship between multiple logical channels through the first auxiliary information, or may indirectly inform the first network device of the association relationship between multiple logical channels through the first auxiliary information.

[0133] Optionally, the first auxiliary information may include an association relationship between multiple logical channels, that is, may include:

[0183] Optionally, in the terminal identifier and / or logical channel identifier included in the first identifier, the terminal identifier may be a unique identifier corresponding to each terminal, such as S-TMSI (Short-Temporary Mobile Subscriber Identity) or C-RNTI (Cell-Radio Network Temporary Identity), and the logical channel identifier uniquely identifies a logical channel within a terminal. The logical channel identifiers used by logical channels corresponding to different terminals may be the same or different.

[0184] Specifically, after the first network device determines that the logical channels with an associated relationship use the same logical channel priority on the Uu interface or the direct communication interface, the first network device can send a first message to the second network device through the interface between network devices (such as the Xn interface) to inform the logical channels with an associated relationship of the same logical channel priority used on the Uu interface or the direct communication interface.

[0185] Optionally, the first network device may inform the second network device of the priority corresponding to any one or more of the multiple logical channels through the first message.

[0200] First configuration information is sent to the one or more terminals, where the first configuration information is used to configure the same logical channel priority for the multiple logical channels that are associated with each other.

[0201] Specifically, if the same logical channel priority used by the associated logical channels in the Uu interface or the direct communication interface is determined by the first network device, the first network device and / or the second network device also needs to send first configuration information to the terminal, in which the same logical channel priority is configured for the associated logical channels.

[0202] Optionally, in a case where the communication device includes at least one terminal among the one or more terminals, the method further includes:

[0203] Based on the second configuration information sent by the network device providing service for the at least one terminal, an association relationship between the multiple logical channels is determined.

[0205] Specifically, if the same logical channel priority used by logical channels with an associated relationship in the Uu interface or the direct communication interface is determined by at least one terminal among one or more terminals, for the terminal, the method for determining the same logical channel priority corresponding to multiple logical channels with an associated relationship for one or more terminals includes but is not limited to: network device configuration and / or terminal determination.

[0206] Optionally, the second configuration information includes at least one of the following:

[0207] A service identifier configured for each bearer and / or logical channel;

[0210] a terminal identifier of a terminal corresponding to a bearer or a logical channel associated with any bearer and / or logical channel among the multiple logical channels;

[0211] A network device identifier of a network device that provides services to a terminal corresponding to a bearer or a logical channel associated with any bearer and / or logical channel among the multiple logical channels.

[0217] A network device identifier of a network device that provides services to a terminal corresponding to a bearer or a logical channel associated with any bearer and / or logical channel among the multiple logical channels.

[0218] Optionally, if the second configuration information includes a service identifier configured for each bearer and / or logical channel, and among the service identifiers configured for each bearer and / or logical channel, some or all of the service identifiers are the same, the terminal can determine that the bearers and / or logical channels with the same service identifiers are associated;

[0220] In one embodiment, the second configuration information includes but is not limited to one or more of the following:

[0221] Configure a common service identifier (such as Common ID or service ID) for each bearer and / or logical channel;

[0224] Determine, based on the logical channel priority configuration information sent by the network device providing services for the terminal, initial logical channel priorities corresponding to the multiple logical channels respectively;

[0225] Based on the initial logical channel priorities respectively corresponding to the multiple logical channels, it is determined that the multiple associated logical channels belonging to the one or more terminals correspond to the same logical channel priority.

[0226] Specifically, when the terminal determines that multiple logical channels with an associated relationship belonging to one or more terminals correspond to the same logical channel priority, it can first obtain the logical channel priority configuration information sent by the network device providing service to the terminal, and the logical channel priority configuration information includes the initial logical channel priorities corresponding to the multiple logical channels, that is, the configured logical channel priorities; but in order to ensure that the associated logical channels use the same logical channel priority on the Uu interface or the direct communication interface, the terminal also needs to adjust the initial logical channel priorities corresponding to the multiple logical channels, so that the multiple logical channels with an associated relationship belonging to the one or more terminals correspond to the same logical channel priority.

[0227] Optionally, the determining that the multiple associated logical channels belonging to the one or more terminals correspond to the same logical channel priority includes any one of the following:

[0228] Using the highest priority among the initial logical channel priorities respectively corresponding to the multiple logical channels as the logical channel priorities corresponding to the multiple logical channels;

[0229] Using the lowest priority among the initial logical channel priorities respectively corresponding to the multiple logical channels as the logical channel priorities corresponding to the multiple logical channels;

[0230] A weighted average of the initial logical channel priorities respectively corresponding to the multiple logical channels is used as the logical channel priorities corresponding to the multiple logical channels.

[0231] Optionally, when the terminal determines that multiple logical channels with an associated relationship belonging to the one or more terminals correspond to the same logical channel priority based on the initial logical channel priorities respectively corresponding to the multiple logical channels, the terminal may perform one or more of the following:

[0238] A weighted average of the initial logical channel priorities respectively corresponding to the multiple logical channels is used as the logical channel priorities corresponding to the multiple logical channels.

[0239] In one embodiment, when the terminal determines that multiple logical channels with an associated relationship belonging to the one or more terminals correspond to the same logical channel priority, the specific implementation method may be one of the following:

[0240] The terminal receives priority configuration information of the logical channel from the network device, and for the logical channels with associated relationships, selects the initial logical channel priority of the logical channel with the highest priority as the logical channel priority used by each logical channel in the logical channel group with associated relationships on the Uu interface and / or the direct communication interface.

[0241] The terminal receives priority configuration information of the logical channel from the network device, and for the logical channels with associated relationships, selects the initial logical channel priority of the logical channel with the lowest priority as the logical channel priority used by each logical channel in the logical channel group with associated relationships on the Uu interface and / or the direct communication interface.

[0242] The terminal receives priority configuration information of the logical channel from the network device, and for the logical channels with associated relationships, performs weighted average on the initial logical channel priority corresponding to each logical channel, and uses the weighted average as the logical channel priority used by each logical channel in the logical channel group with associated relationships on the Uu interface and / or the direct communication interface.

[0243] Optionally, the same logical channel priority corresponding to multiple associated logical channels at the Uu interface is used for the logical channel prioritization LCP process.

[0244] Optionally, the same logical channel priority corresponding to multiple logical channels associated with the direct communication interface is used for at least one of the following:

[0245] Logical channel prioritization LCP process;

[0246] Determine the priority indicated by the direct communication interface control information SCI;

[0247] In case of a conflict between uplink UL transmission and direct communication link SL transmission, priority UL transmission or priority SL transmission is determined.

[0248] Specifically, the "same logical channel priority" can be used in the Uu interface to determine the LCP (Logical Channel Prioritization) process, and in the direct communication interface it can be used for one or more of the following: determining the LCP process, determining the priority contained in the SCI (Sidelink Control Information), and determining whether UL transmission or SL transmission is prioritized when there is a UL / SL transmission conflict.

[0249] In one embodiment, taking the first network device determining the same priority as an example, Figure 4This is a second flow chart of the method for determining the priority of a logical channel provided in an embodiment of the present application, such as Figure 4 As shown, the specific steps include:

[0250] Step 1: The second network device sends first auxiliary information to the first network device;

[0251] Optionally, this step may be performed only when multiple logical channels having an associated relationship are served by different network devices.

[0252] For example, in a DC (Dual Connectivity) scenario, one part of the associated logical channels is the logical channel corresponding to the MN (Master Node) terminated bearer, and the other part is the logical channel corresponding to the SN (Secondary Node) terminated bearer.

[0253] Specifically, the second network device sends first auxiliary information to the first network device through an interface between network devices (such as an Xn interface), where the first auxiliary information includes at least one of the following:

[0271] The mapping relationship between the QoS Flow identifier and the logical channel identifier may also carry the terminal identifier to which the logical channel belongs.

[0272] Specifically, the content of the first auxiliary information may come from the second network device or a DU (Distributed Unit) corresponding to the second network device. The content of the first auxiliary information is used to assist the first network device in determining associated logical channels of multiple terminals served by different network devices.

[0273] Optionally, the first network device may also determine a group of logical channels with which the Uu interface has an associated relationship according to auxiliary information obtained from the core network or auxiliary information reported by the terminal.

[0274] Optionally, the auxiliary information may include one or more of the following:

[0275] Public business identification information (such as Common ID or business ID)

[0276] The association relationship between QoS (Quality of Service) Flows. If the QoS Flows belong to different terminals, the terminal identifier and / or the network device identifier to which the terminal belongs must also be included.

[0277] Optionally, the first network device determines a group of logical channels with an associated relationship based on the auxiliary information, the mapping relationship between QoS Flow and DRB, and / or the mapping relationship between DRB and logical channels.

[0278] Step 2: The first network device determines the logical channel priority;

[0279] Optionally, after the first network device determines the association relationship between multiple logical channels of one or more terminals, the associated logical channels use the same logical channel priority on the Uu interface or the direct communication interface. How to determine the same logical channel priority may depend on the implementation of the first network device.

[0280] Optionally, after the first network device determines the association relationship between multiple logical channels of one or more terminals, the associated logical channels use the same logical channel priority on the Uu interface or the direct communication interface, which can be determined based on any of the following:

[0281] Using the highest priority among the initial logical channel priorities respectively corresponding to the multiple logical channels as the logical channel priorities corresponding to the multiple logical channels;

[0282] Using the lowest priority among the initial logical channel priorities respectively corresponding to the multiple logical channels as the logical channel priorities corresponding to the multiple logical channels;

[0283] A weighted average of the initial logical channel priorities respectively corresponding to the multiple logical channels is used as the logical channel priorities corresponding to the multiple logical channels.

[0284] Step 3: The first network device sends a first message to the second network device through the network device interface;

[0285] Optionally, if the associated logical channels correspond to multiple different terminals, and the different terminals are served by different network devices, step 3 is executed; otherwise, step 3 may be omitted.

[0286] Specifically, the first network device determines that the associated logical channels use the same logical channel priority on the Uu interface or the direct communication interface, and then the first network device sends a first message to the second network device through the network device interface (such as the Xn interface). The first message includes at least one of the following:

[0287] a logical channel priority corresponding to a logical channel belonging to the second network device and having an associated relationship with the logical channel belonging to the first network device;

[0288] a logical channel priority corresponding to the first identifier belonging to the second network device and having an associated relationship with the logical channel belonging to the first network device;

[0293] The first identifier includes at least one of the following: a terminal identifier and a logical channel identifier.

[0294] For example, the first message includes at least the logical channel priority, and may also include one or more of the following:

[0295] A public business identifier (such as Common ID or business ID);

[0296] Logical channel identifier;

[0297] The terminal identifier to which the logical channel belongs.

[0298] Step 4: The first network device and / or the second network device sends first configuration information to the terminal.

[0299] Specifically, the first network device and / or the second network device sends first configuration information to the terminal, in which the same logical channel priority is configured for logical channels having an associated relationship.

[0300] In one embodiment, taking the terminals determining the same priority as an example, Figure 5 This is a flowchart of the method for determining the priority of a logical channel provided in an embodiment of the present application. Figure 5 As shown, the specific steps include:

[0301] Step 1: The terminal determines a logical channel with an associated relationship;

[0302] For a terminal, methods for determining associations between different logical channels of one or more terminals include but are not limited to:

[0303] Network equipment configuration;

[0304] Terminal confirmed.

[0305] If the network device configuration method is adopted, the second configuration information includes at least one of the following:

[0306] A service identifier configured for each bearer and / or logical channel;

[0307] QoS Flow identifier corresponding to each bearer and / or logical channel;

[0308] an identifier of a bearer or a logical channel associated with any bearer and / or a logical channel among the multiple logical channels;

[0309] a terminal identifier of a terminal corresponding to a bearer or a logical channel associated with any bearer and / or logical channel among the multiple logical channels;

[0310] A network device identifier of a network device that provides services to a terminal corresponding to a bearer or a logical channel associated with any bearer and / or logical channel among the multiple logical channels.

[0311] For example, the second configuration information of the network device includes but is not limited to one or a combination of the following:

[0312] Configure a common service identifier (such as Common ID or service ID) for each bearer and / or logical channel;

[0313] Other bearers or logical channel identifiers associated with the bearer or logical channel, wherein if the other bearers or logical channels belong to other terminals, they also need to carry terminal identification information and / or identification information of the network device to which the terminal belongs.

[0314] If the terminal determination method is adopted, the terminal can determine the associated logical channel based on the inter-layer interaction information provided by the terminal high layer, the mapping relationship between QoSFlow and DRB, and / or auxiliary information sent by other terminals through the direct communication interface (such as the mapping relationship between data flow QoSFlow and DRB or logical channel).

[0315] Step 2: The terminal determines to use the same logical channel priority for the logical channels having an associated relationship;

[0316] The “same logical channel priority” is determined by the terminal, that is, the terminal determines that multiple associated logical channels belonging to the one or more terminals correspond to the same logical channel priority, including any of the following:

[0317] Using the highest priority among the initial logical channel priorities respectively corresponding to the multiple logical channels as the logical channel priorities corresponding to the multiple logical channels;

[0318] Using the lowest priority among the initial logical channel priorities respectively corresponding to the multiple logical channels as the logical channel priorities corresponding to the multiple logical channels;

[0319] A weighted average of the initial logical channel priorities respectively corresponding to the multiple logical channels is used as the logical channel priorities corresponding to the multiple logical channels.

[0320] For example, the specific implementation manner in which the “same logical channel priority” is determined by the terminal may be one of the following:

[0321] The terminal receives priority configuration information of the logical channel from the network device, and for the associated logical channels, selects the priority of the logical channel with the highest priority as the logical channel priority used by each logical channel in the associated logical channel group on the Uu interface and / or the direct communication interface.

[0322] The terminal receives priority configuration information of the logical channel from the network device, and for the logical channels with associated relationships, selects the priority of the logical channel with the lowest priority as the logical channel priority used by each logical channel in the logical channel group with associated relationships on the Uu interface and / or the direct communication interface.

[0323] The terminal receives priority configuration information of the logical channel from the network device, and for the logical channels with associated relationships, performs weighted average on the logical channel priorities corresponding to each logical channel, and uses the weighted average as the logical channel priority used by each logical channel in the logical channel group with associated relationships on the Uu interface and / or the direct communication interface.

[0324] Step 3: The terminal notifies other terminals of the priorities of the associated logical channels through the direct communication interface;

[0325] Optionally, this step needs to be performed only when the associated logical channels belong to different terminals.

[0326] For example, if these associated logical channels belong to multiple terminals respectively, after one of the terminals determines that the associated logical channels use the same logical channel priority, the terminal can inform other terminals among the multiple terminals of the same logical channel priority used by the associated logical channels.

[0327] Step 4: The terminal applies the same logical channel priority;

[0328] For example, the LCP process is performed on the logical channels with associated relationships;

[0329] For example, setting the priority in the direct communication interface SCI;

[0330] For example, the UL or SL priority may be determined, that is, when there is a conflict between uplink UL transmission and direct communication link SL transmission, priority UL transmission or priority SL transmission may be determined.
