Detailed Description
So that the manner in which the features and technical contents of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the present invention will be rendered by reference to the appended drawings, which are included for purposes of illustration and not limitation.
Before describing embodiments of the present invention in detail, a brief description of data replication transmission will be provided.
The research object is expanded in the Release16 topic, and the business aiming at factory automation (factory automation), transportation industry (transportation industry) and electric power distribution (electric power distribution) is expanded to the topic of 5G IIoT; thus, the concept of Time Sensitive Network (TSN) was introduced. Thus, the issues of 5G IIoT will be for TSN related enhancements, intra-user priority and Data replication (Data replication) transmission and multi-connectivity. A schematic diagram of a data replication transmission architecture, as shown in fig. 1; as shown in (Data Resource Bearer, DRB) ID2 between the terminal device and the base station in fig. 1, a Dual Connectivity (DC) Data replication transmission scheme adopts a split Bearer (split Bearer) architecture. A Packet Data Convergence Protocol (PDCP) entity associates two different Radio Link Control (RLC) entities; one entity corresponds to a Primary Cell Group (MCG) and one entity corresponds to a Secondary Cell Group (SCG). For uplink transmission Data and downlink transmission Data, a PDCP entity copies a PDCP Protocol Data Unit (PDU) into two identical parts, and the two PDCP entities reach a corresponding MAC entity and RLC entity of a terminal device or a base station through an RLC entity of a different cell group, a different Media Access Control (MAC) entity, and an air interface; finally converging to a PDCP layer; when the PDCP layer detects that the data received by the two PDCP entities are the same data obtained after copying, if it is determined that the data are the same data obtained after copying through the two PDCP PDUs having the same sequence Number (Serial Number), one of the data is discarded, and the other data is delivered to the higher layer.
Carrier Aggregation (CA) data duplication transmission scheme as shown in DRB ID1 or DRB ID3 in fig. 1, a PDCP entity is associated with two different RLC entities, and the two RLC entities are associated with the same MAC entity. For uplink transmission data and downlink transmission data, the PDCP entity copies the PDCP PDU into two same parts, and the two PDCP entities reach corresponding MAC entities and RLC entities of terminal equipment or a base station through different RLC entities and the same MAC entity of a cell group and an air interface; finally converging to a PDCP layer; when the PDCP layer detects that the data received by the two PDCP entities are the same data obtained after copying, if it is determined that the data are the same data obtained after copying through the two PDCP PDUs having the same sequence Number (Serial Number), one of the data is discarded, and the other data is delivered to the higher layer.
In the related art, when data copy transmission is performed, the uplink PDCP data copy function is configured based on the DRB, that is, the uplink PDCP data copy transmission configures data copy transmission with the DRB as a granularity, so as to control activation or deactivation of data copy transmission. In specific implementation, corresponding information is added to a PDCP-config IE in a Radio Resource Control (RRC) reconfiguration message to configure a bearer-based data replication scheme. Indicating activation or deactivation based on the MAC CE, namely indicating to adopt PDCP to copy data transmission or not adopt PDCP to copy data transmission; if the MAC CE for activating or deactivating the PCDP duplicated data transmission comprises an 8-bit bitmap, the bits in the bitmap respectively correspond to different DRBs, and the activation or deactivation of the corresponding DRBs for data duplicated transmission is indicated through different values in the bits; if the bit value is 0, indicating to deactivate data copy transmission; a bit value of 1 indicates that data copy transmission is activated.
However, data replication in the related art can only be transmitted through two paths, that is, one data packet is replicated once, so that the application scenario of data replication transmission is limited; and, the terminal device can only determine whether to perform data copy transmission and the manner of performing data copy transmission by the instruction of the base station. The method for determining the data copy transmission mode through the base station indication by the terminal device not only has poor flexibility, but also may cause the data copy transmission mode that the base station indicates the terminal device to be unsuitable because the base station is unclear about the downlink channel quality.

In specific implementation, the first indication information is used to indicate the terminal device to determine the first data copying manner, or indicate the terminal device to determine the first data copying manner. As, the first indication information is used to indicate: first data replication information autonomously determined by the terminal device; or first data replication information determined by the terminal device according to indication information from a network; or first data copying information determined by the terminal device according to the first indication information; or the first data replication information determined by the negotiation between the terminal device and the network device. Or the first data replication information determined by the terminal device according to the second data replication information and/or the first policy; or the first data replication information further determined by the terminal device based on second data replication information. As, the first indication information is used to indicate: a data replication mode autonomously determined by the terminal device; or the data copying mode determined by the terminal equipment according to the indication information from the network; or the terminal equipment determines the data copying mode according to the first indication information; or the terminal equipment and the network equipment negotiate a determined data copying mode; or the terminal equipment determines a data copying mode according to the second data copying information and/or the first strategy; or a data replication mode further determined by the terminal device based on the second data replication information. Specifically, for example, the terminal device determines, based on the first indication information, that the path identifier or the path used in the data copy transmission may be determined by the terminal device itself or the terminal device participates in the determination.
The first information includes at least one of: channel Quality information, a Service mode (pattern), Quality of Service (QoS) information, a size of data to be transmitted in a cache, an available time-frequency resource size, a priority of a logical channel to be transmitted, a priority of a logical channel group to be transmitted, a logical channel identifier to be transmitted, a logical channel group identifier to be transmitted, a Service identifier carried/established by a terminal device, Internet Protocol (IP) information, an Ethernet (Ethernet) address of a data packet, a copy indication, a specific Service, a specific bearer, a specific data packet, a type of Service to be transmitted, and an available time-frequency resource attribute. Wherein the service QoS information comprises at least one of the following: delay level, reliability level, delay, reliability, period, packet size, Service priority, Service type, and Qos Flow Identifier (QFI). Optionally, the size of the data to be transmitted in the buffer is the size of the data to be transmitted in the PDCP buffer and/or the size of the data to be transmitted in the RLC buffer. The size of the available time frequency resource is the size of the available time frequency resource of the MAC layer. The available time-frequency resource attributes include at least one of: time frequency resource priority, time frequency resource identification and time frequency resource Link Control Protocol (LCP) restriction attribute; such as available subcarrier spacing (SCS), Physical Uplink Shared Channel (PUSCH) duration (duration). The channel quality information may be determined by at least one of: reference signal measurement values, Hybrid Automatic Repeat-reQuest (HARQ) information, and Automatic Repeat-reQuest (ARQ) information. Wherein the reference signal measurements comprise: signal to Interference plus Noise Ratio (SINR), Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Received Signal Strength Indication (RSSI).
The data replication mode comprises at least one of the following modes: determining whether to adopt a bearer corresponding to data replication; whether data copy transmission is adopted or not; the number of times of data replication; when data copy transmission is not adopted, a used path identifier or path is used; the number of paths for data replication transmission is adopted; a path identifier or a path used in data copy transmission; granularity of data replication transmission; the data replicates the objects of the transmission.
In the implementation, it is determined whether to use a bearer corresponding to the data copy transmission, that is, it is determined whether to activate the data copy transmission or deactivate the data copy transmission on that bearer. Whether to employ data copy transmission, including activating data copy transmission and deactivating data copy transmission, or using data copy transmission and not using data copy transmission. The path identity includes a logical channel identity and/or an RLC identity. The number of paths includes the number of logical channels and/or the number of RLC. The number of data copies includes: the number of data copies per path and/or the total number of data copies. For example, when the number of data copies is the total number of data copies, and the total number of data copies is 4, the used path is 2, and 3 copies of the data may be transmitted through one path and 1 copy of the data may be transmitted through the other path. When the number of times of data copying is the number of times of copying of each path, the number of times of copying of each path is 1, and the number of paths transmitted by data copying is 4, the transmitted data is 4. In the embodiment of the invention, as the number of the paths adopting the data copying transmission can be more than 2, the application range of the data copying transmission is expanded.
The granularity of data replication transmission includes at least one of: packet-based granularity, QoS flow-based (flow) granularity, PDU session-based granularity, IP quintuple-based granularity, Ethernet address-based granularity, DRB-based granularity, and terminal device-based granularity.

Optionally, for the same bearer, the terminal device may employ one or more than two granularities of data copy transmission. The granularity of data copy transmission of more than two types is used for the same bearer by the terminal device for example. For example, DRB1 carries packet 1 and a packet with a QFI value of 1, and packet 1 does not belong to a QoS flow with a QFI value of 1; and QoF-based data replication transmission is performed on the data packet with the QFI value of 1, and packet-based data replication transmission is performed on the packet 1. Wherein a QFI value of 1 refers to a QoS flow identified as 1. In the embodiment of the invention, the granularity of data replication transmission is divided more finely, for example, the granularity based on the data packet can indicate the replication data transmission with finer granularity. Taking the granularity of the network device configuration or the indication data copy transmission as the QFI granularity as an example, when the network device simultaneously configures or indicates the data copy transmission of the corresponding QFI or QFI list, the terminal device performs the copy transmission of the data packet corresponding to the determined QFI or QFI list. And if the QFI configured by the network equipment for the terminal equipment is 2, the terminal equipment performs copy transmission on the data packet with the QFI of 2. Taking the granularity of the network device configuration or the indication data copy transmission as the granularity based on the data packet as an example, the network device simultaneously configures or indicates the data copy transmission data packet IP information, or the identification information, or the specific priority information, and the terminal device performs the copy transmission on the data packet corresponding to the configured or indicated data packet IP, or the identification or the priority. And if the IP of the data packet configured for the terminal equipment by the network equipment is A, the terminal equipment copies and transmits the data packet with the IP of A.

Optionally, the data replication method further includes: data packets with data replication are carried. When the granularity of data copy transmission is based on the granularity of data packets or QoS flow granularity, the terminal equipment determines the data packets adopting data copy in the bearer based on at least one of the following items: PDU session identification, QFI and duplicate transport assistance information. The QFI may be obtained from the packet header corresponding to the SDAP through the PDCP entity, or may be indicated by an upper layer or carried by a transmitted packet. When the granularity of data copy transmission is based on the granularity of a data packet or based on the granularity of a PDU session, the terminal equipment determines the data packet adopting data copy in the bearer based on at least one of the following items: PDU session identity, QFI and duplicate transmission assistance information.

In some embodiments, the terminal device can determine, according to the first information, a data replication manner required for data replication transmission, that is, the terminal device can independently determine how to perform data replication transmission according to the first information, without combining a data replication manner sent by the network device or a pre-configured data replication manner.
In other embodiments, the terminal device cannot independently determine a data copying mode required for data copying transmission according to the first information; or according to the factors such as protocol agreement, configuration information and the like, the terminal equipment determines a data replication mode required by data replication transmission by combining the first data replication information determined by the terminal equipment and the second data replication information sent by the network equipment. In this scenario, as shown in fig. 4, another optional processing flow of the data copying method applied to the terminal device includes, in addition to step S201, the method further includes:
step S202, the terminal equipment receives the second data copy information sent by the network equipment.
Here, the second data replication information is used to indicate a data replication mode, and the second data replication information is sent to the terminal device by the network device through a dedicated signaling, that is, the dedicated signaling carries the second data replication information. Optionally, the dedicated signaling comprises: RRC message, MAC CE and DCI signaling. In particular implementation, the second data replication information is determined by the network device according to the first information; or the second data replication information is determined according to the first data replication information sent to the network equipment by the terminal equipment; or the second data replication information is determined according to the first data replication information and the first information which are sent to the network equipment by the terminal equipment; the first information may be acquired by the network device itself, or may be sent to the network device by the terminal device.
In this embodiment of the present invention, the data replication method indicated by the first data replication information may be completely the same as, partially the same as, or completely different from the data replication method indicated by the second data replication information. For example, the first data copy information includes: whether data copy transmission and the load bearing of data copy transmission are adopted; the second data replication information includes: not adopting a path identifier used in data copying transmission, granularity of data copying transmission and data copying times; at this time, the data copy manner indicated by the first data copy information is completely different from the data copy manner indicated by the second data copy information.
In some embodiments, when the terminal device determines that the first data replication information and the second data replication information include completely different data replication modes according to the first information, the terminal device determines first information in the first data replication data based on the first data replication information, and determines second information in the first data replication data based on the second data replication information, wherein the first data replication data includes the first information and the second information; or the terminal device determines first information in the first data copying mode based on the first data copying information, and determines second information in the first data copying mode based on the second data copying information, wherein the first data copying mode comprises the first information and the second information. For example, the terminal device determines that the data copy manner included in the first data copy information is at least one of the following: whether data copy transmission is adopted, whether a bearer corresponding to the data copy is adopted or not is determined, the data copy frequency is determined, and a path identifier is used when the data copy transmission is not adopted; the terminal equipment determines that the data replication mode included in the second data replication information is at least one of the following modes: the number of paths for data copy transmission, the path or path identification used in data copy transmission, the granularity of data copy transmission, and the object of data copy transmission are used. The data replication method finally determined by the terminal device includes a data replication method of at least one corresponding data replication information: whether data replication transmission is adopted, whether a bearer corresponding to the data replication is adopted or not is determined, the data replication frequency is determined, and a path or a path identifier is used when the data replication transmission is not adopted; and a data replication method of a corresponding at least one of the second data replication information: the number of paths for data copy transmission, the path or path identification used in data copy transmission, the granularity of data copy transmission, and the object of data copy transmission are used.
In some embodiments, the first data copy information and the second data copy information determined by the terminal device according to the first information include a part or all of the same data copy mode, and for the same data copy mode, when the content indicated by the first data copy information is different from the content indicated by the second data copy information, the terminal device adopts the content indicated by the corresponding first data copy mode in the second data copy information; or the terminal equipment adopts the content indicated by the first data copying mode in the first copying information; or, the terminal device determines the content indicated by the first data copying mode based on the first copying information and the second copying information; or, the terminal device determines the content indicated by the first data copying manner based on the second copying information and/or a first policy, where the first policy is configured or preset by a network device; or, the terminal device determines or further determines the content of the first data copy manner based on the second copy information. For example, when the first data copy information and the second data copy information determined by the terminal device based on the first information both include the number of data copies, the first data copy information indicates that the number of data copies is 4, and the second data copy information indicates that the number of data copies is 8, the terminal device may adopt the number of data copies as 4 or the number of data copies as 8. In addition, when the terminal device adopts the content indicated in the second data copy information, so that the terminal device cannot realize data copy transmission based on the first data copy information, the terminal device may adaptively modify the data copy mode indicated in the first data copy information. For another example, when the terminal device performs transmission by using the path 1,2,3,4 according to the second data replication information, if the first data replication information determined by the terminal device uses a different path for data replication transmission, the terminal device needs to further update the path for data replication transmission to be 1,3 or 1,5, and the number of the transmitted replicated data is 8. For another example, when the terminal device performs transmission by using the path 1,2,3,4 according to the second data replication information, if the value of the number of times of data replication transmission in the first data replication information determined by the terminal device is different, the terminal device needs to further update the number of times of data replication transmission, but selects the path 1,2,3,4 for transmission. Or the terminal equipment simultaneously updates the times of data copying transmission and the path of the data copying transmission.
The content indicated by the first data copying mode is determined by the terminal device based on the first copying information and the second copying information; taking the data replication mode as the data replication transmission, taking the path identifier used as an example, if the terminal device determines that the path identifiers used for data replication transmission are 1 and 2 based on the first replication information, determines that the path identifier used for data replication transmission is 3 based on the second replication information, and finally determines that the path identifiers used for data replication transmission are 1,2, and 3. Or, if the terminal device determines that the path identifiers used in data copy transmission are 1 and 2 based on the first copy information, determines that the path identifiers used in data copy transmission are 1 and 3 based on the second copy information, and finally determines that the path identifier used in data copy transmission is 1.
The content indicated by the first data copying mode is determined by the terminal device based on the second copying information and a first strategy; taking the data replication mode as the number of paths adopting data replication transmission as an example, if the number of paths adopting data replication transmission is determined to be 2 based on the second replication information, and the first policy indicates that the number of paths adopting data replication transmission is less than 4, the terminal device finally determines the number of paths adopting data replication transmission to be 2. Taking the data replication mode as the number of paths adopting data replication transmission as an example, if the number of paths adopting data replication transmission is determined to be 4 based on the second replication information, and the first policy indicates that the number of paths adopting data replication transmission is 2, the terminal device finally determines the number of paths adopting data replication transmission to be 2. Optionally, the first policy may agree on information of the number of paths, RLC entities, carriers, and the like that support or select data replication transmission at most at the same time. Optionally, the first policy may be preconfigured or network indicated.
Then, the content indicated by the first data copying mode is determined by the terminal device based on the second copying information and a first policy for example; the first policy may be information or a policy on how to determine a data replication manner when the second replication information and the first replication information collide; alternatively, the first policy may be information or a policy on how to determine the data replication method when the second replication information is received. For example, when the network device indicates that the used or activated path (leg) is leg1, leg2, and leg3, the UE selects legs that are finally used for data replication transmission based on the first policy and the three legs indicated by the network, e.g., leg1 and leg2 are selected legs that are finally used for data replication transmission from leg1, leg2, and leg 3. For another example, when the legs indicated to be used or activated by the network device are legs 1, legs 2, and legs 3, the UE determines that the largest number of legs used for transmitting the duplicated data is 2 and selects the leg to be finally used for the data duplication transmission based on the first policy and the three legs indicated by the network, such as legs 1 and legs 2 selected from legs 1, legs 2, and legs 3.
Then, the content indicated by the first data copying mode is determined by the terminal device based on the second copying information for example; taking the data replication mode as the path of data replication transmission as an example, the terminal device selects the leg finally used for data replication transmission from the activated legs used for data replication transmission indicated by the network device. Specifically, the network device indicates the used or activated legs as leg1, leg2, and leg3, and the UE selects legs ultimately used for data replication transmission based on the three legs indicated by the network, e.g., leg1 and leg2 are selected from leg1, leg2, and leg3 as legs ultimately transmitting replicated data.
In other embodiments, when the first data copy information determined by the terminal device and the second data copy information include completely different data copy manners, the terminal device updates the first data copy information based on the second copy information, or the terminal device determines partial information of the data copy manners based on the second copy information, or the terminal device determines another partial information of the data copy manners based on the second copy information. Optionally, in other embodiments, when the first data copy information determined by the terminal device according to the first information and the second data copy information completely differ from each other in data copy manner, the terminal device updates the first data copy information based on the second copy information, or the terminal device determines partial information of the data copy manner based on the second copy information, or the terminal device determines another partial information of the data copy manner based on the second copy information. It can be understood that the terminal device stores the data copy manner indicated in the second copy information into the first copy information to update the first copy information. And the terminal equipment performs data copying transmission based on the data copying mode indicated by the updated first copying information. For example, the terminal device determines to perform data replication transmission on the DRB1, where the second data replication information indicates that a path identifier for data transmission is a logical channel identifier, and the path identifier is transmitted using logical channels identified as 1 and 2; the terminal device determines to transmit the DRB1 using the logical channels identified as 1 and 2. Or the terminal device determines the data replication mode according to the first data replication information and the second data replication information when the first data replication information and the second data replication information determined by the terminal device are completely different in data replication mode.
Based on the above description, when determining the data replication mode, the terminal device in the embodiments of the present invention may determine the data replication mode by itself, may also determine the data replication mode according to the configuration of the network device or the indication of the network device, and may also determine the data replication mode by negotiation between the terminal device and the network device.
