Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Fig. 1 is a schematic view of a dual connectivity operating mode scenario, in which two network nodes connected to a UE are a primary base station 101 and a secondary base station 102, it should be noted that, in an LTE architecture, a base station in this embodiment may be an enhanced base station (eNB), and in a fifth Generation (5G, 5th-Generation) communication technology architecture, a base station in this embodiment may be a gNB. Since the LTE architecture is taken as an example to describe the technical solution in this embodiment, the primary base station and the secondary base station in the embodiment may be a menb (masterenb) and a senb (secondary enb), respectively.
As can be seen from fig. 1, the UE is simultaneously in the coverage of the main base station 101 (as shown by the solid oval in fig. 1) and the coverage of the secondary base station 102 (as shown by the dashed oval in fig. 1), so that the bearer splitting technique can be adopted for both uplink transmission and downlink transmission of the UE, so that both uplink transmission and downlink transmission of the UE can be transmitted on the bearers of the main base station 101 and the secondary base station 102, respectively.
For the bearers of the primary base station 101 and the secondary base station 102, three categories can be distinguished: the first type is a Master Cell Group bearer (MCGbearer), that is, a bearer which is only located in the MeNB and only uses MeNB resources; the second type is Secondary Cell Group bearer (SCG bearer), that is, a bearer which is located only in the SeNB and uses only SeNB resources; the third type is a Split bearer (Split bearer), i.e. a bearer that is simultaneously localized to the MeNB and SeNB and uses the MeNB and SeNB resources simultaneously.
For the Split bearer, as shown in fig. 2, different PDUs of the same PDCP may be mapped to the Logical Channel 1 of the MeNB and may also be mapped to the Logical Channel 2 of the SeNB for transmission, as described in the foregoing.
Further, in the CA scenario, PDUs of the same PDCP may be mapped to different logical channels for transmission, and may also be mapped to different carriers for transmission.
According to the above scenario, when the UE transmits duplicate (duplicate) data, the duplicate data may be mapped to different logical channels for transmission, or may be mapped to different carriers for transmission.
Example one
An embodiment of the present invention provides a method for transmitting duplicate data, which is applied to a communication device, and as shown in fig. 3, the method may include:
s101, acquiring a first data packet corresponding to a first bearer, wherein the first bearer is a bearer for bearer data or a signaling data packet.
In an embodiment of the present invention, a communication device may include: user equipment or network side equipment. When the communication device is a user device, the transmission of the repeated data provided by the embodiment of the invention is the transmission of the uplink repeated data, namely, the first data packet is the uplink data to be transmitted at this time; when the communication device is a network side device, the transmission of the duplicate data provided by the embodiment of the present invention is the transmission of downlink duplicate data, that is, the first data packet is the downlink data to be transmitted at this time.
In the embodiment of the present invention, data is transmitted between the user equipment and the network side equipment, and the method for transmitting duplicate data provided in the embodiment of the present invention is applicable to both the user equipment and the network side equipment.
It should be noted that when the communication device uses the first bearer to perform the current service, data transmission needs to be performed between the user equipment and the network side device, so that when the communication device in the embodiment of the present invention is the user equipment, an opposite end of the communication device is the network side device; when the communication device in the embodiment of the present invention is a network side device, the opposite end of the communication device is a user device.
In this embodiment of the present invention, the communication device may obtain a first data packet corresponding to a first bearer, where the first bearer is a bearer used by an ongoing communication service, and the first bearer is a bearer carrying data or a signaling data packet.
Optionally, the first Data Packet may be a Protocol Data Unit (PDU) of a Packet Data Convergence Protocol (PDCP), a PDU of a radio link layer Control Protocol (RLC), a PDU of a Medium Access Control (MAC), a Service Data Unit (SDU) of the PDCP, an SDU of the RLC, or an SDU of the MAC.
Specifically, first, the communication device obtains an original data packet for implementing a first bearer; then, the communication device sets a first identifier corresponding to the logical channel in the original data packet to obtain a first data packet. That is to say, in the embodiment of the present invention, each bearer of the communication device may transmit through a non-dedicated logical channel, but an identifier of the logical channel through which the first data packet is transmitted for the first time, that is, a first identifier, is set in a first data packet corresponding to each bearer (corresponding to each service).
In this way, after the communication device obtains the first data packet, the communication device may transmit the first data packet on different logical channels, that is, the communication device transmits the first data packet on at least one preset logical channel, where the at least one preset logical channel includes a non-dedicated logical channel corresponding to the first bearer. Specifically, the first data packet and the second data packet are transmitted on different non-dedicated logical channels, after which the communication device may determine the carrier on which the first data packet is transmitted, which is specifically the process described in the following section in the embodiment of the present invention.
S102, detecting whether the first data packet is a repeated data packet of the transmitted second data packet.
After acquiring the first packet corresponding to the first bearer, the communication device may detect whether the first packet is a duplicate packet of a transmitted second packet because the first packet may be transmitted for the first time or may be a duplicate packet of a repeatedly transmitted second packet, where the second packet is a packet of new data transmitted before the first packet is transmitted. If the first data packet is a data packet which is not transmitted, the first data packet is represented as new data; if the first data packet is a duplicate data packet of the transmitted second data packet, the data representing the first data packet is the duplicate data which has been transmitted before and is the same as the data of the second data packet.
Specifically, in the embodiment of the present invention, the communication device may record the record of the transmission data each time, so that the communication device may detect the transmission data record before the first data packet is transmitted this time, and find out whether a data packet identical to the first data packet transmitted this time is transmitted. The same data packet as the first data packet transmitted this time may be the second data packet, or may be a duplicate data packet of the second data packet transmitted before.
It should be noted that, in the method for transmitting duplicate data provided in the embodiment of the present invention, in order to improve reliability of data transmission when the communication device communicates with the opposite end of the communication device, the communication device may transmit the data packet corresponding to one service for the number of times of repetition. The repeated data provided by the embodiment of the invention is obtained in the same way.
S103, when the first data packet is a repeated data packet of the transmitted second data packet, determining a first carrier for transmitting the first data packet according to a preset rule, wherein the first carrier is at least one carrier in available carriers; the preset rule is a rule for judging that the data packets with the same data are transmitted on different carriers within a preset time.
After detecting whether the first data packet is a duplicate data packet of the transmitted second data packet, the communication device may obtain two results, one is: the first data packet is a duplicate data packet of the transmitted second data packet, and the other data packet is: the first packet is an untransmitted packet, i.e. new data. In this case, when the first packet is a duplicate packet of the transmitted second packet, it is characterized that the first packet is the duplicate packet at this time, and therefore, the communication device may determine the first carrier used for transmitting the first packet according to the preset rule, where the purpose is to transmit the first packet and the previously transmitted same data on different carriers within the preset time, that is, the preset rule in the communication device determines the rule for transmitting the packet with the same data on different carriers within the preset time. And when the first data packet is the data packet of the new data, the first data packet is transmitted by utilizing the bearer.
It should be noted that, in the embodiment of the present invention, the available carrier is a carrier that can be used by the communication device for data transmission. The preset time may be defined differently according to the preset rule.
In an embodiment of the invention, the current time instant at which the first data packet is to be transmitted is within the current transmission time interval.
Based on the premise that the first packet is a duplicate packet of the transmitted second packet, a specific process of the communication device determining the first carrier for transmitting the first packet according to a preset rule is described as follows:
optionally, the transmitted third data packet is the second data packet, or the transmitted third data packet is a duplicate data packet of the second data packet and the second data packet.
That is, before the first packet is transmitted, the transmitted third packet may be the second packet, i.e. the new data, or may be the new data or the duplicate data (duplicate) that has been transmitted again.
(1) The communication equipment acquires a second carrier wave of the transmitted third data packet; the communication device determines any one carrier other than the second carrier as the first carrier from the available carriers.
It should be noted that the second carrier is a generic term of a carrier that transmits the third data packet, and may include at least one carrier, and the specific number of the carriers is determined according to the number of carriers that actually transmit the third data packet, which is not limited in the embodiment of the present invention. The available carrier of the communication device may also be multiple carriers, and the communication device determines multiple carriers other than the second carrier from the available carriers, and then determines any one of the multiple carriers as the first carrier, so as to implement transmission of the first data packet on the first carrier.
Here, the preset rule may be a B rule that the communication apparatus first transmits new data on one carrier, and when transmitting duplicate data, the communication apparatus needs to transmit duplicate data on a carrier on which the new data and the duplicate have not been transmitted before. Alternatively, the preset rule may be a D rule, that is, the communication device first transmits new data on one carrier, and when transmitting duplicate data, the communication device needs to transmit duplicate data on a carrier on which the new data has not been transmitted before.
It should be noted that, when the preset rule may be a B rule and a D rule, the preset time may be different transmission time intervals.
(2) The communication equipment acquires a first transmission time interval of the third data packet; when the first transmission time interval is a transmission time interval before the current transmission time interval, the communication equipment determines any carrier except the second carrier as a first carrier from the available carriers; when the first transmission time interval is not a transmission time interval previous to the current transmission time interval, the communication device determines any one carrier as the first carrier from the available carriers.
Here, the preset rule may be an a rule that the communication device first transmits new data on one carrier, and when the duplicate data is transmitted, the duplicate data needs to be transmitted on a carrier on which the new data and the duplicate have not been transmitted last time. Or, the preset rule may be a C rule, that is, the communication device first transmits new data on one carrier, and when transmitting duplicate data, the duplicate data needs to be transmitted on a carrier on which the new data was not transmitted last time.
It should be noted that, when the preset rule may be the a and C rules, the preset time may be different transmission time intervals.
(3) When the first transmission time interval is the same as the current transmission time interval, the communication equipment determines any carrier except the second carrier from the available carriers as a first carrier; when the first transmission time interval is different from the current transmission time interval, the communication device determines any one carrier as a first carrier from the available carriers.
Here, the preset rule may be an E rule that the new data and the duplicate data of the communication device in the same TTI transmission time interval cannot simultaneously transmit the duplicate data on the same carrier.
It should be noted that, when the preset rule may be an E rule, the preset time may be a time of the same transmission time interval.
Illustratively, as shown in fig. 4, at time T1, when a UE (communication device) receives a grant (grant information) on carrier 1, the UE carries new data transmission, although at this time, grant resources are left and cannot be filled with duplicate data. At time T2, the UE receives the grant on carrier 1 again, where carrier 1 is the second carrier that has transmitted the third data packet, and if according to rule a-D, the UE cannot transmit duplicate data on carrier 1, but if according to rule E, because the grants of T1 and T2 do not belong to the same TTI, duplicate data can be transmitted at time T2. At time T3, the UE receives the grant on carrier 2, and the new data or the duplicate data has not been transmitted on carrier 2, at this time, the UE may transmit the duplicate data on carrier 2. At time T4, the UE receives the grants on carriers 1, 2, and 3 simultaneously, and at this time, if the duplicate data according to rule a can be mapped to carrier 1 for transmission, but if the duplicate data according to rule B can be mapped to carrier 3 for transmission. Wherein TI, T2, T3, and T4 belong to different transmission time intervals.
Further, when the first data packet is a first data packet to be transmitted, the communication device may determine one carrier from available carriers to transmit the first data packet. The repeated data transmission method provided by the embodiment of the invention can be adopted to realize the subsequent transmission of the repeated data packet of the first data packet.
And S104, transmitting the first data packet at the current transmission time interval of the first carrier.
When the first data packet is a transmitted data packet, after the communication device determines the first carrier used for transmitting the first data packet according to the preset rule, the communication device may transmit the first data packet at the current transmission time interval of the first carrier because the communication device has found the first carrier used for transmitting the first data packet.
It can be understood that, in the embodiment of the present invention, when one communication device transmits communication data, it may implement, according to a preset rule, transmission of a data packet with the same data on different carriers within a preset time, so as to implement transmission of the same certain data (new data and duplicate data are the same data) on different carriers, and ensure a probability of successful transmission of the certain data, thereby improving reliability of mobile communication (data transmission).
Further, as shown in fig. 5, before S101, a method for transmitting duplicate data according to an embodiment of the present invention further includes: and S105. The following were used:
and S105, acquiring available carriers.
It should be noted that, in the embodiment of the present invention, data needs to be transmitted by using a carrier as a carrier, and a carrier that can be used by a communication device for transmission is referred to as an available carrier in the embodiment of the present invention. Therefore, before data transmission is performed, it is necessary to acquire available carriers of the communication apparatus.
However, since the communication device may include: user equipment or network side equipment. Therefore, the manner of acquisition of available carriers of one communication apparatus is also different.
Specifically, when the communication device is a user device, the available carrier is obtained from the transmission configuration information sent by the network side device; and when the communication equipment is network side equipment, acquiring the available carrier waves from the preset transmission configuration.
It should be noted that, in the embodiment of the present invention, the process of acquiring an available carrier by the communication device may occur when the communication device and the communication device communicate with each other by interworking a notification message when the segment starts to communicate.
Example two
An embodiment of the present invention further provides a method for transmitting duplicate data, which is applied to a communication device, and as shown in fig. 6, the method includes:
s201, obtaining an original data packet for realizing a first bearer, wherein the first bearer is a bearer for carrying data or a signaling data packet.
S202, setting a first identifier corresponding to the logic channel in the original data packet to obtain a first data packet.
S203, transmitting the first data packet on at least one preset logical channel, where the at least one preset logical channel includes a non-dedicated logical channel corresponding to the first bearer.
In an embodiment of the present invention, a communication device may include: user equipment or network side equipment. When the communication device is a user device, the transmission of the repeated data provided by the embodiment of the invention is the transmission of the uplink repeated data, namely, the first data packet is the uplink data to be transmitted; when the communication device is a network side device, the transmission of the duplicate data provided by the embodiment of the present invention is the transmission of downlink duplicate data, that is, the first data packet is the downlink data to be transmitted.
In the embodiment of the present invention, data is transmitted between the user equipment and the network side equipment, and the method for transmitting duplicate data provided in the embodiment of the present invention is applicable to both the user equipment and the network side equipment.
It should be noted that when the communication device uses the first bearer to perform the current service, data transmission needs to be performed between the user equipment and the network side device, so that when the communication device in the embodiment of the present invention is the user equipment, an opposite end of the communication device is the network side device; when the communication device in the embodiment of the present invention is a network side device, the opposite end of the communication device is a user device.
In this embodiment of the present invention, the communication device may obtain a first data packet corresponding to a first bearer, where the first bearer is a bearer used by an ongoing communication service.
Specifically, first, the communication device obtains an original data packet for implementing a first bearer; then, the communication device sets a first identifier corresponding to the logical channel in the original data packet to obtain a first data packet. That is to say, in the embodiment of the present invention, each bearer of the communication device may transmit through a non-dedicated logical channel, but an identifier of the logical channel through which the first data packet is transmitted for the first time, that is, a first identifier, is set in a first data packet corresponding to each bearer (corresponding to each service). Finally, the communication device transmits the first data packet on the preset at least one logical channel.
In this way, after the communication device obtains the first data packet, the communication device may transmit the first data packet on different logical channels, that is, the communication device transmits the first data packet on at least one preset logical channel, where the at least one preset logical channel includes a non-dedicated logical channel corresponding to the first bearer.
In the embodiment of the invention, the communication equipment transmits the first data packet and the data packet (the second data packet or the repeated data packet of the second data packet) of the same data transmitted last time on different non-exclusive logical channels, so that the transmission of the same data on different logical channels is realized, and the reliability of data transmission is improved.
Optionally, in this embodiment of the present invention, the first identifier is set in a logical label field in header information of PDCP, header information of RLC, header information of MAC, or a Quality of Service flow identifier (Qosflow ID); alternatively, Qosflow ID is used as the first identifier.
It should be noted that multiple uplink and downlink Qos flows can be mapped to one logical channel, and each IP packet of the Qos flow carries a Qos flow ID. The Qosflow ID is encapsulated by the upper layer protocol of PDCP.
For example, as shown in fig. 7, a communication device transmits Data to an opposite end of the communication device through a Logical Channel 1(Logical Channel 1) and a Logical Channel 2(Logical Channel 2), where the Logical Channel 1 and the Logical Channel 2 are two preset Logical channels, where the Logical Channel 1 carries normal transmission Data (a first Data packet) of a Data Radio Bearer (DRB) 1 (corresponding to the first Bearer), and meanwhile, the Logical Channel 1 may be configured as a duplicate Logical Channel of a DRB2, and similarly, the Logical Channel 2 carries normal transmission Data (a second Data packet) of a DRB2 and may be configured as a duplicate Logical Channel of a DRB 1. In this way, the duplicate data (first packet) of the DRB1 can be placed on logical channel 2 for transmission. However, it needs to identify which logical channel the data packet of this logical channel comes from, for example, a data packet with LC-1 SN-1 transmitted on logical channel 2 indicates that the data with SN-1 comes from the repeated data on logical channel 1, and LC-1 is the identifier corresponding to the logical channel, where the identifier of the logical channel, that is, the LC field, may be added to the PDU header information of the PDCP or RLC.
Illustratively, the Qos flow, the IP and the DRB are mapped respectively, and when the communication device performs uplink Qos flow mapping or downlink Qos flow mapping, the uplink and downlink data packets may carry information of a Qos flow ID, if the first data packet is a first data packet, since the first data packet corresponds to a first bearer, the Qos flow ID corresponds to the first bearer, and then a field of a label of a logical channel corresponding to the first bearer is set in the Qos flow ID. Therefore, the QoS flow ID can be used for distinguishing whether the data packet is a repeated data packet or not by the communication equipment.
In the embodiment of the present invention, the labels of the Logical channels set in the Qos flow IDs on different Logical channels on the communication device are not repeatable, as shown in fig. 8, when mapping downlink Qos flow, the Qos flow IDs on Logical Channel 1 are all Qos flow IDs 1, and the Qos flow IDs on Logical Channel 2 are all Qos flow IDs 2; when mapping the uplink Qos flow, the Qos flow IDs on the Logical Channel 1 are all Qos flow IDs 4, and the Qos flow IDs on the Logical Channel 2 are all Qos flow IDs 3. Thus, when the opposite end of the communication device receives the transmission data packet, the PDCP layer of the opposite end of the communication device needs to solve the Qos flow ID of the data packet, determine, according to the Qos flow ID, which bearer (corresponding to which logical channel) the data packet actually comes from (for example, the duplicate data from the DRB 1), and then put the data packet into the data re-ordering window of the DRB1 to participate in data ordering.
It can be understood that, with the transmission method of the duplicated data provided in the embodiment of the present invention, even when the communication device performs transmission of the first data packet corresponding to the first bearer and the fourth data packet corresponding to the second bearer on the preset at least one non-proprietary logical channel, because the bearer or the data packet corresponding to the service from which the data packet is transmitted is marked when the data packet is transmitted, the opposite end of the communication device can analyze data of the same bearer according to the first identifier to put the data of the same bearer on the corresponding bearer for rearrangement, that is, different data packets can be transmitted on the same logical channel without causing confusion of data transmission, thereby improving reliability of mobile communication. Meanwhile, the data packets of the same data can also be transmitted on different logical channels, and since the data packet corresponding to which bearer or service the data packet comes from is marked when the data packet is transmitted, the opposite end of the communication device can analyze the data of the same bearer according to the first identifier so as to put the data of the same bearer on the corresponding bearer for rearrangement, that is, different data packets can be transmitted on the same logical channel without causing data transmission confusion, thereby improving the reliability of mobile communication.
