Description

Logical channel priority determination method and device

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 202310947478.4, filed on July 28, 2023, entitled “Logical Channel Priority Determination Method and Device,” which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to the field of communication technology, and in particular to a method and device for determining a logical channel priority. Background Art

[0004] Dedicated Radio Bearer (DRB) transmission is scheduled at the MAC (Media Access Control) layer. In existing technologies, base stations allocate uplink resources to a single terminal. To ensure fairness across different uplink logical channels for the same terminal and prevent some services from being starved, existing technologies employ a Logical Channel Priority (LCP) mechanism based on logical channel priority and Prioritized Bit Rate (PBR).

[0005] The LCP mechanism based on logical channel priority and PBR is as follows: after the terminal obtains an uplink resource grant (UL grant), the first round of resource allocation is performed for each logical channel with data transmission requirements according to the PBR in descending order of 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.

[0006] During the LCP process, the data transmission priority of each logical channel is determined independently. Therefore, synchronization of multiple QoS flows corresponding to the same service, such as multimodal XR (eXtended Reality) services, over the air interface cannot be guaranteed, potentially impacting the user experience.

[0130] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0131] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0132] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0133] First, let’s introduce the following contents:

[0134] (1) Basic process of air interface data processing;

[0135] Figure 1 is a schematic diagram of the user plane protocol stack provided by the relevant technology. As shown in Figure 1, 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.

[0136] When a QoS Flow (Quality of Service) reaches the SDAP, SDAP maps the QoS Flow to a DRB (Dedicated Radio Bearer), forming an SDAP PDU (Protocol Data Unit). The SDAP PDU is the PDCP SDU (Service Data Unit). The PDCP layer performs header compression, encryption, and other operations on the PDCP SDU before delivering it to the RLC layer. The RLC layer then encapsulates the RLC PDU based on the MAC layer scheduling information and delivers it to the MAC. The MAC encapsulates the received RLC PDU into a MAC PDU and delivers it to the physical layer for transmission.

[0137] 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.

[0138] (2) Basic concepts of XR;

[0139] The communication system has introduced XR (eXtended Reality) services, which are divided into the following categories:

[0140] AR (Augmented Reality): seamless integration of the real and virtual worlds, half real and half fake

[0141] VR (Virtual Reality) uses devices to simulate a virtual world that is completely fake. MR (Mixed Reality) contains both real physical entities and virtual information.

[0142] As communication systems evolve, extended reality (XR) services are being introduced. XR services can involve multiple user devices, such as 3D glasses and controllers.

[0143] There are two basic ways to connect XR services to wireless networks: Method 1: All user devices are connected to a single user equipment (UE), and XR services access the wireless network through this terminal. In this method, the same terminal must coordinate the transmission of different streams within a single XR service, also known as intra-UE multi-modal. Method 2: Different user devices access the wireless network as separate terminals. In this method, multiple terminals must coordinate the transmission of different streams within a single XR service, also known as inter-UE multi-modal.

[0144] Figure 2 is a schematic diagram of the structure of an XR service data frame provided by an embodiment of the present disclosure. As shown in Figure 2, the same data frame can be divided into multiple packet data units (PDUs). Among them, a PDU set is defined as follows: one or more PDUs corresponding to the same information unit constitute a PDU set.

[0145] XR services support multimodality. In multimodality, multiple QoS flows of a service are transmitted synchronously during air interface transmission (also known as coordinated transmission).

[0146] In the LCP process in the related art, the data transmission priority of each logical channel is determined independently. There is no correlation between the transmissions of different LCHs (Logical Channels, downlink logical channels) and no synchronous transmission is performed.

[0147] The embodiments of the present disclosure provide a method and apparatus for determining logical channel priorities to enable synchronous transmission of different QoS flows corresponding to the same service during air interface transmission, thereby meeting the synchronous transmission requirements of multimodal services.

[0148] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0149] The technical solution provided by the embodiment of the present disclosure 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.

[0150] FIG3 is a flow chart of a method for determining a logical channel priority according to an embodiment of the present disclosure. As shown in FIG3 , the method for determining a logical channel priority is applied to a communication device, that is, the execution subject of the method for determining a logical channel priority is a communication device, such as a terminal or a first network device. The method for determining a logical channel priority includes the following steps:

[0151] Step 300: Determine that multiple logical channels associated with one or more terminals have the same logical channel priority.

[0152] 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 the Uu interface or a logical channel of the direct communication interface.

[0153] Optionally, multiple logical channels correspond to the same logical channel priority, which may indicate that the multiple logical channels correspond to the same logical channel priority on the Uu interface or the direct communication interface.

[0154] 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.

[0155] In an embodiment of the present disclosure, the same logical channel priority corresponding to multiple logical channels with an associated relationship can be determined by at least one terminal among the one or more terminals to which the multiple logical channels with an associated relationship belong, or by a first network device that provides services to any one of the one or more terminals.

[0156] Optionally, the first network device may be a base station, a CU (Central Unit), or a DU (Distributed Unit), etc.

[0157] Optionally, if the same logical channel priority corresponds to multiple associated logical channels, it is determined by the first network device providing services to 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.

[0158] This disclosure proposes a method for determining logical channel priority for services with synchronization requirements, such as XR services. This method can maximize the equality of one or more terminals transmitting the same multimodal service when obtaining air interface resources, better ensure that multiple streams can be transmitted synchronously on the air interface, and prevent service starvation due to the low priority of one logical channel, thereby affecting the overall service performance.

[0159] The logical channel priority determination method provided in the embodiment of the present disclosure 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.

[0163] The second network device includes a network device that provides services for at least one of the one or more terminals, and the second network device is different from the first network device.

[0164] Specifically, when multiple logical channels with an associated relationship are served by different network devices (i.e., a first network device and a second network device), the second network device needs to send first auxiliary information to the first network device through an interface between network devices (such as an Xn interface) so that the first network device can know the associated relationship between the multiple logical channels.

[0180] a mapping relationship between the QoS Flow identifier and the first identifier belonging to the second network device;

[0181] The first identifier includes at least one of the following: a terminal identifier and a logical channel identifier.

[0182] Optionally, the first identifier includes a terminal identifier and a logical channel identifier, wherein the terminal identifier can 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 can be identified by LCID (Logical Channel Identity); the logical channels under different terminals can use the same or different LCIDs.

[0183] Optionally, in the terminal identifier and / or logical channel identifier included in the first identifier, the terminal identifier can 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 the logical channels corresponding to different terminals can be the same or different.

[0184] 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.

[0185] Optionally, the first auxiliary information may include an association relationship between multiple logical channels, that is, may include:

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 logical channels with an associated relationship 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.

[0290] 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.

[0291] In one embodiment, when the terminal determines that multiple logical channels associated with the one or more terminals correspond to the same logical channel priority, the specific implementation manner may be one of the following:

[0292] 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 direct communication interface.

[0293] 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 direct communication interface.

[0294] The terminal receives priority configuration information of the logical channel from the network device, and for the logical channels with associated relationships, performs weighted averaging 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 direct communication interface.

[0295] Optionally, the same logical channel priority corresponding to multiple logical channels in an associated relationship on the Uu interface is used for a logical channel prioritization LCP process.

[0296] 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:

[0297] Logical channel prioritization LCP process;

[0298] Determine the priority indicated by the direct communication interface control information SCI;

[0299] In case of a conflict between uplink UL transmission and direct communication link SL transmission, priority UL transmission or priority SL transmission is determined.

[0300] Specifically, the "same logical channel priority" can be used to determine the LCP (Logical Channel Prioritization) process in the Uu interface, and can be used for one or more of the following in the direct communication interface: determining the LCP process, determining the priority contained in the SCI (Sidelink Control Information, direct communication interface control information), and determining whether to prioritize UL transmission or SL transmission when UL / SL transmission conflicts.

[0301] In one embodiment, taking the case where the first network device determines the same priority as an example, FIG4 is a second flow chart of a method for determining the priority of a logical channel provided in an embodiment of the present disclosure. As shown in FIG4 , the method specifically includes the following steps:

[0302] Step 1: The second network device sends first auxiliary information to the first network device;

[0303] Optionally, this step may be performed only when multiple logical channels with an associated relationship are served by different network devices.

[0304] For example, in a DC (Dual Connectivity) scenario, part of the associated logical channels are logical channels corresponding to the MN (Master Node) terminated bearer, and the other part are logical channels corresponding to the SN (Secondary Node) terminated bearer.

[0305] 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:

[0324] Specifically, the first auxiliary information may be derived from the second network device or a DU (Distributed Unit) corresponding to the second network device. 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.

[0325] Optionally, the first network device may further 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.

[0326] Optionally, the auxiliary information may include one or more of the following:

[0327] Public business identification information (such as Common ID or business ID)

[0328] 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.

[0329] 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.

[0330] Step 2: The first network device determines the logical channel priority;

[0331] 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.

[0332] 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 one of the following:

[0333] 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;

[0334] 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;

[0335] 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.

[0336] Step 3: The first network device sends a first message to the second network device through the network device interface;

[0337] 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 can be omitted.

[0338] 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:

[0339] a logical channel priority corresponding to a logical channel belonging to the second network device and associated with the logical channel belonging to the first network device;

[0340] A logical channel priority corresponding to the first identifier of the second network device and associated with the logical channel of the first network device;

[0345] The first identifier includes at least one of the following: a terminal identifier and a logical channel identifier.

[0346] For example, the first message includes at least the logical channel priority and may also include one or more of the following:

[0347] Public business identifier (such as Common ID or business ID);

[0348] Logical channel identifier;

[0349] The terminal identifier to which the logical channel belongs.

[0350] Step 4: The first network device and / or the second network device sends first configuration information to the terminal.

[0351] Specifically, the first network device and / or the second network device sends first configuration information to the terminal, where the first configuration information configures the same logical channel priority for the associated logical channels.

[0352] In one embodiment, taking the case where terminals determine the same priority as an example, FIG5 is a flowchart of a third method for determining the priority of a logical channel provided by an embodiment of the present disclosure. As shown in FIG5 , the method specifically includes the following steps:

[0353] Step 1: The terminal determines the logical channels with associated relationships;

[0354] For a terminal, methods for determining associations between different logical channels of one or more terminals include but are not limited to:

[0355] Network device configuration;

[0356] Terminal confirmed.

[0357] If a network device configuration method is used, the second configuration information includes at least one of the following:

[0358] Service identifier configured for each bearer and / or logical channel;

[0359] QoS Flow identifier corresponding to each bearer and / or logical channel;

[0360] an identifier of a bearer or logical channel associated with any bearer and / or logical channel among the multiple logical channels;

[0361] a terminal identifier of a terminal corresponding to a bearer or logical channel associated with any bearer and / or logical channel among the multiple logical channels;

[0362] A network device identifier of a network device that provides services to a terminal corresponding to a bearer or logical channel associated with any bearer and / or logical channel among the multiple logical channels.

[0363] For example, the second configuration information of the network device includes but is not limited to one or a combination of the following:

[0364] Configure a common service identifier (e.g., Common ID or service ID) for each bearer and / or logical channel;

[0365] Identifiers of other bearers or logical channels associated with the bearer or logical channel. If the other bearers or logical channels belong to other terminals, they also need to carry identification information of the terminal and / or identification information of the network device to which the terminal belongs.

[0366] 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 QoS Flow and DRB, and / or auxiliary information sent by other terminals through the direct communication interface (such as the mapping relationship between data flow QoS Flow and DRB or logical channel).

[0367] Step 2: The terminal determines to use the same logical channel priority for the associated logical channels;

[0368] The “same logical channel priority” is determined by the terminal, that is, the terminal determines that multiple logical channels with associated relationships belonging to the one or more terminals correspond to the same logical channel priority, including any of the following:

[0369] 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;

[0370] 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;

[0371] 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.

[0372] For example, the specific implementation manner in which the “same logical channel priority” is determined by the terminal may be one of the following:

[0373] 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 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 direct communication interface.

[0374] 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 direct communication interface.

[0375] The terminal receives priority configuration information of the logical channel from the network device, and for the logical channels with associated relationships, performs weighted averaging 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 direct communication interface.

[0376] Step 3: The terminal notifies other terminals of the priorities of the associated logical channels through the direct communication interface;

[0377] Optionally, this step needs to be performed only when the associated logical channels belong to different terminals.

[0378] 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.

[0379] Step 4: The terminal applies the same logical channel priority;

[0380] For example, the LCP process is performed on the logical channels with associated relationships;

[0381] For example, setting the priority in the direct communication interface SCI;

[0382] For example, UL or SL priority may be determined, that is, when uplink UL transmission and direct communication link SL transmission conflict, priority UL transmission or priority SL transmission may be determined.
