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

Referring to fig. 3, it illustrates an activation method for duplicate data transmission according to an embodiment of the present invention, which may be applied to a network device, and the method may include:

s301: determining activation information for the terminal device;

the activation information includes parameter information required for repeated data transmission by the terminal device.

S302: transmitting the activation information to the terminal device;

the activation information is used for activating the terminal equipment to send repeated data.

Here, the network device may be a management device on the network side, or may be a base station on the network side, as long as the management of the terminal device is possible, which is not exhaustive in this embodiment.

It can be understood that, after receiving the activation information, the terminal device not only transmits the repeated data, but also transmits the repeated data according to the parameter information included in the activation information.

In an optional implementation manner, before performing S302, the network device may set a logical channel and/or a carrier capable of performing repeated data transmission for the terminal device; specifically, the method may be implemented by the network device sending a configuration instruction to the terminal device, where the configuration instruction includes an indication of a logical channel and/or a carrier that is specified by the network device for the terminal device and can be used for sending repeated data. After receiving the configuration command, the terminal device can perform repeated data transmission through the logical channel and/or carrier specified in the configuration command.

It should be noted that the type of signaling may include, but is not limited to, Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling, and physical layer signaling, and therefore, for S302, the transmitting the activation information to the terminal device specifically includes:

and transmitting the activation information to the terminal equipment by adopting RRC signaling, MAC signaling or physical layer signaling.

For the foregoing configuration instruction, in an optional implementation manner, if the activation information is transmitted by using RRC signaling, the configuration instruction may be transmitted by using the RRC signaling together with the activation information, in addition to the configuration instruction being sent before executing S302, so that the number of interactions from the network device to the terminal device can be reduced, and the network load can be reduced.

Further, for determining activation information for the terminal device in S301, there may be the following exemplary scenarios, which are respectively described below:

scene one

And determining the times of repeated transmission of the data packet needing to be repeatedly transmitted by the terminal equipment.

It should be noted that, when the terminal device performs new transmission (i.e., first transmission) on a certain data packet that needs to be repeatedly transmitted, the number of times of repeatedly transmitting the data packet is 1; when the terminal device performs one new transmission and N repeated transmissions on a certain data packet which needs to be repeatedly transmitted, the number of times of repeatedly transmitting the data packet is N + 1. This embodiment is not described in detail.

In this scenario, the network device may acquire information such as current network quality, load condition, or channel quality, and evaluate the current network environment according to the acquired information, where the specific evaluation manner may perform weighted analysis on the acquired information, and distinguish analysis results by different grades; such as three levels of low, medium and high, a higher level indicates a better network environment. The network device may determine, according to a correspondence between a preset network environment level and the number of times of repeated transmission, the number of times of repeated transmission of a single data packet by the terminal device. For example, if the network environment level is high, the network device determines that the terminal device needs to repeatedly transmit a single data packet twice, that is, the terminal device needs to perform a new transmission and a repeated transmission for a certain data packet that needs to be repeatedly transmitted.

It can be understood that the number of times of repeatedly transmitting the data packet that needs to be repeatedly transmitted may correspond to a feature of a network environment, and may also correspond to more features.

The activation information provided in this scenario is the number of times of repeated transmission of the data packet that needs to be repeatedly transmitted, so that the terminal device can transmit repeated data according to the number of times of repeated transmission of the data packet that needs to be repeatedly transmitted in the activation information after receiving the activation information. Therefore, a specific implementation scheme for activating the UE to perform repeated data transmission is provided.

Scene two

And determining the bearers required to transmit the repeated data packets by the terminal equipment and the times of repeated transmission of the data packets required to be repeatedly transmitted corresponding to each bearer.

In this scenario, the bearer that needs to send the duplicate packets may be a logical channel or a carrier; different from the logical channels and/or carriers in the configuration instructions, the indication of the logical channels and/or carriers included in the configuration instructions represents the logical channels and/or carriers capable of repeating data transmission; thus, the bearers described in this scenario that require the sending of duplicate packets may be a subset of the logical channels and/or carriers included in the configuration instructions.

Specifically, each bearer has a corresponding data packet that needs to be repeatedly sent, and therefore, the number of times that the data packet that needs to be repeatedly sent is repeatedly sent for each bearer can be implemented by referring to the determination process of the number of times of repeated sending in the scenario one, which is not described in detail in this scenario.

Scene three

Determining the bearers required to transmit the repeated data packets by the terminal equipment and the quantity of the data packets required to be repeatedly transmitted corresponding to each bearer.

Specifically, the network device may obtain data transmission quality corresponding to each bearer, and perform quality classification for each bearer according to the transmission quality, where the higher the classification is, the higher the transmission quality of the bearer is. The network device may compare the quality level corresponding to each bearer with a preset quality level threshold, and a bearer higher than the quality level threshold is determined as a bearer for the terminal device to send a duplicate packet; subsequently, the number of data packets that need to be repeatedly transmitted corresponding to each bearer can be determined according to the data packet transmission capability corresponding to each quality level.

In this scenario, taking a MAC Control Element (CE, Control Element) in the MAC signaling as an example, when the activation information is transmitted by using the MAC signaling, the bearers that the terminal device needs to send the duplicate data packets and the number of data packets that need to be sent repeatedly and correspond to each bearer may be encapsulated in the MAC CE, where a specific encapsulation structure is shown in fig. 4, and the function identifier represents that the signaling is used to activate the terminal device to send the duplicate data; a Resource Block (RB) identifier represents a bearer which needs to send a repeated data packet; the PDU number marks represent the number of data packets which need to be repeatedly sent by the bearer; the number is counted as the number of PDU packets of the PDCP.

In addition, the activation information in this scenario may also be transmitted by using a Physical layer signaling, such as a Physical Downlink Control Channel (PDCCH).

The activation information provided in this scenario is the bearer that needs to send the duplicate data packets and the number of the data packets that need to be sent repeatedly and correspond to each bearer, so that the terminal device can send the duplicate data according to the bearer that needs to send the duplicate data packets and the number of the data packets that need to be sent repeatedly and correspond to each bearer in the activation information after receiving the activation information. Therefore, another specific implementation scheme for activating the UE for repeated data transmission is provided.

Scene four

And determining the bearers required to transmit the repeated data packets by the terminal equipment and the data quantity required to be repeatedly transmitted corresponding to each bearer.

The difference between the scenario and scenario three is that each bearer that needs to send repeated data packets in the scenario corresponds to the amount of data that needs to be sent repeatedly instead of the number of data packets; the data amount is counted in bytes Byte, and the number of PDU packets of the non-PDCP is counted.

In this scenario, when the activation information is transmitted by using an MAC signaling, bearers that the terminal device needs to send the duplicate data packets and data volumes that need to be sent repeatedly and correspond to each bearer may be encapsulated in the MAC CE, where a specific encapsulation structure is shown in fig. 5, and the functional identifier represents that the signaling is used to activate the terminal device to send the duplicate data; a Resource Block (RB) identifier represents a bearer which needs to send a repeated data packet; the Byte number marks represent the number of data packets which need to be repeatedly sent by the bearer; the number is counted in bytes of PDU packets of the PDCP.

Similar to the third scenario, the activation information in the present scenario may also be transmitted by using a Physical layer signaling, such as a Physical Downlink Control Channel (PDCCH).

The activation information provided in this scenario is the bearer that needs to send the duplicate data packet and the data amount that needs to be sent repeatedly and corresponds to each bearer, so that the terminal device can send the duplicate data according to the bearer that needs to send the duplicate data packet and the data amount that needs to be sent repeatedly and corresponds to each bearer in the activation information after receiving the activation information. Therefore, the specific implementation scheme for activating the UE for repeated data transmission is provided.

Scene five

And determining the bearers required to transmit the repeated data packets by the terminal equipment and the repeated transmission duration corresponding to each bearer.

The difference between this scenario and scenario two is that each bearer that needs to send a duplicate packet in this scenario corresponds to a duration for performing repeated sending, and this duration may be timed in seconds, for example, 200 seconds; it may also be clocked in Transmission Time Intervals (TTI), for example 500 TTIs. Therefore, the terminal equipment can transmit the repeated data on each bearer which needs to transmit the repeated data packet according to the corresponding duration.

In this scenario, when the activation information is transmitted by using an MAC signaling, bearers that the terminal device needs to send the duplicate data packet and the duration of the duplicate transmission corresponding to each bearer may be encapsulated in the MAC CE, where a specific encapsulation structure is shown in fig. 6, and the functional identifier represents that the signaling is used to activate the terminal device to send the duplicate data; a Resource Block (RB) identifier represents a bearer which needs to send a repeated data packet; the duration identifies the duration of the repeated transmission of the bearer, which may be 200 seconds, or 500 TTIs, for example.

Scene six

Determining the bearers required to transmit the duplicate packets, and the starting Sequence Number (SN) of the Packet Data Convergence Protocol (PDCP) and/or the ending SN of the PDCP for each bearer.

The difference between this scenario and scenario two is that each bearer that needs to send a duplicate packet in this scenario corresponds to a location indication for sending the duplicate packet on the PDCP, which may include three situations, namely, a start SN of the PDCP, an end SN of the PDCP, and a start SN of the PDCP and an end SN of the PDCP.

In this scenario, when the activation information is transmitted by using an MAC signaling, bearers that need to send the duplicate packets, and a start sequence number SN of a packet data convergence protocol PDCP and/or an end SN of the packet data convergence protocol PDCP that are used by each bearer to send the duplicate packets may be encapsulated in the MAC CE, where a specific encapsulation structure is shown in fig. 7, and the function identifier represents that the signaling is used to activate the terminal device to send the duplicate packets; a Resource Block (RB) identifier represents a bearer which needs to send a repeated data packet; as shown in fig. 7(1), only the initial SN of PDCP is encapsulated in MAC CE; as shown in fig. 7(2), only the ending SN of PDCP is encapsulated in the MAC CE; and as shown in FIG. 7(3), the MAC CE encapsulates the starting SN of the PDCP and the ending SN of the PDCP.

For the description of the above six scenarios, optionally, the duplicate packets to be sent may be Protocol Data Units (PDUs) of a Packet Data Convergence Protocol (PDCP), PDUs of a Radio Link Control Protocol (RLC), PDUs of a Medium Access Control (MAC), Service Data Units (SDUs) of the PDCP, SDUs of the RLC, or SDUs of the MAC.

Through the description of the six scenarios, the present embodiment explains some preferred parameter information included in the activation information and required by the terminal device to perform the repeated data transmission. It can be understood that, since the activation information may include a combination of one or more of the above five parameter information, the technical solutions described in the above six scenarios may also be combined arbitrarily according to the actual needs of those skilled in the art. This embodiment will not be described in detail.

Example two

Based on the same inventive concept of the foregoing embodiment, referring to fig. 8, it illustrates an activation method for duplicate data transmission provided in an embodiment of the present invention, where the method may be applied to a terminal device, and the method may include:

s801: receiving activation information sent by network equipment;

the activation information is used for activating the terminal equipment to send repeated data; and the activation information includes parameter information required for the terminal device to perform repeated data transmission.

S802: and repeating data transmission according to the activation information.

It should be noted that, since the type of the signaling may include, but is not limited to, Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling, and physical layer signaling, the activation information described in S801 may specifically be transmitted by using RRC signaling, MAC signaling, or physical layer signaling.

Before performing S802, the network device may set a logical channel and/or a carrier capable of performing repeated data transmission for the terminal device, and therefore the method according to this embodiment further includes: and receiving a configuration instruction sent by the network equipment, wherein the configuration instruction comprises an indication of a logic channel and/or a carrier wave which is specified by the network equipment for the terminal equipment and can be used for repeated data transmission. Therefore, after receiving the configuration command, the terminal device can perform repeated data transmission through the logical channel and/or the carrier specified in the configuration command.

It should be noted that, for the configuration instruction, if the activation information is transmitted by using RRC signaling, the configuration instruction may also be transmitted by using the RRC signaling together with the activation information, so as to reduce the number of interactions from the network device to the terminal device and reduce the network load.

Further, corresponding to the embodiment, in the present embodiment, for S802, there may be the following scenarios on the terminal device side, which are described below:

scene one

When the activation information includes the number of times of repeated transmission of the terminal device for the data packet which needs to be repeatedly transmitted, the terminal device transmits repeated data according to the number of times of repeated transmission of the data packet which needs to be repeatedly transmitted.

It should be noted that, when the terminal device performs new transmission for a certain packet that needs to be repeatedly transmitted, the number of times of repeatedly transmitting the data packet is 1; when the terminal device performs one new transmission and N repeated transmissions for a certain data packet to be repeatedly transmitted, the number of times of repeatedly transmitting the data packet is N + 1. This embodiment is not described in detail.

Taking the number of times that the terminal device repeatedly transmits the data packet that needs to be repeatedly transmitted as two examples, it indicates that the terminal device needs to perform one new transmission and one repeated transmission on the data packet, as shown in fig. 9, a process of the terminal device performing repeated data transmission according to the number of times that the terminal device repeatedly transmits the data packet that needs to be repeatedly transmitted may include:

the terminal device receives grant from carrier 1, carrier 2, and carrier 3 at time T1, where in fig. 9, the received grant is indicated by a box, and a blank space is left if no grant is received. Therefore, at time T1, the terminal device may perform repeated data transmission on carrier 1, carrier 2, and carrier 3, but only the data packet with SN equal to 1 is data that needs to be repeatedly transmitted at this time, and therefore, the terminal device may select a carrier, such as carrier 2, from carrier 1, carrier 2, and carrier 3 that does not perform repeated data transmission; thus, the terminal device may perform repeated data transmission on carrier 1 and carrier 3, for example, newly transmit a data packet with SN 1 on carrier 1, and repeatedly transmit a data packet with SN 1 on carrier 3.

The terminal device receives only the grant from the carrier 1 at time T2, and the data that needs to be repeatedly transmitted at this time are the data packet with SN-2 and the data packet with SN-3, and because there is only the grant of the carrier 1, the terminal device selects to newly transmit the data packet with SN-2 on the carrier 1.

Since the terminal device receives the grant from carrier 1, carrier 2, and carrier 3 at the same time at T3, the terminal device performs the repeated data transmission not completed at T2, and thus the terminal device completes the repeated transmission of the data packet with SN equal to 2, the data packet with SN equal to 3, and the data packet with SN equal to 3 on different carriers, and in fig. 9, the terminal completes the repeated transmission of the data packet with SN equal to 2 through carrier 2, the data packet with SN equal to 3 through carrier 1, and the repeated transmission of the data packet with SN equal to 3 through carrier 3 at T3.

Scene two

And when the activation information comprises the bearers needing to send the repeated data packets and the times of repeatedly sending the data packets needing to be repeatedly sent and corresponding to each bearer, the terminal equipment sends the repeated data on the bearers needing to send the repeated data packets according to the times of repeatedly sending the data packets needing to be repeatedly sent and corresponding to each bearer.

Specifically, each bearer has a corresponding data packet that needs to be repeatedly transmitted, and in combination with scenario one, the data packet that needs to be repeatedly transmitted has the number of times of repeated transmission. Therefore, after acquiring the number of times of repeatedly transmitting the data packet which needs to be repeatedly transmitted and corresponds to each bearer, the terminal device performs repeated data transmission on the bearer which needs to transmit the repeated data packet according to the number of times of repeatedly transmitting the data packet which needs to be repeatedly transmitted and corresponds to each bearer.

Scene three

When the activation information includes the bearers required to send the duplicate data packets and the number of the data packets required to be repeatedly sent corresponding to each bearer, the terminal device sends the duplicate data packets on the bearers required to send the duplicate data packets according to the number of the data packets required to be repeatedly sent corresponding to each bearer.

In addition, the number of duplicate packets to be transmitted can be counted by the number of PDU packets of the PDCP.

Specifically, the activation information is transmitted by using MAC signaling, such as MAC CE; physical layer signaling, such as PDCCH, may also be employed for transmission. This embodiment will not be described in detail.

Scene four

When the activation information includes the bearer requiring to send the duplicate data packet and the data volume requiring to be repeatedly sent corresponding to each bearer, the terminal device sends the duplicate data packet on the bearer requiring to send the duplicate data packet according to the data volume requiring to be repeatedly sent corresponding to each bearer.

The difference between the scenario and the scenario two is that each bearer requiring to send repeated data packets in the scenario corresponds to the data amount required to be sent repeatedly, rather than the data packet amount; the data amount is counted in bytes Byte, and the number of PDU packets of the non-PDCP is counted.

Similar to scenario three, the activation information may be transmitted using MAC signaling, such as MAC CE; physical layer signaling, such as PDCCH, may also be employed for transmission.

Scene five

And when the activation information comprises the bearer which needs to transmit the repeated data packet and the duration time of the repeated transmission corresponding to each bearer, the terminal equipment transmits the repeated data on the bearer which needs to transmit the repeated data packet according to the duration time of the repeated transmission corresponding to each bearer.

The difference between this scenario and scenario two is that each bearer that needs to send a duplicate packet in this scenario corresponds to a duration for performing repeated sending, and this duration may be timed in seconds, for example, 200 seconds; it may also be clocked in Transmission Time Intervals (TTI), for example 500 TTIs. Therefore, the terminal device may perform the repeated data transmission according to the respective corresponding duration on each bearer that needs to perform the repeated data packet transmission.

Scene six

When the activation information includes bearers required to send the duplicate packets, and a start sequence number SN of a packet data convergence protocol PDCP and/or an end SN of the packet data convergence protocol PDCP used by each bearer to send the duplicate packets, the terminal device sends duplicate packets on the bearers required to send the duplicate packets according to the start SN of the packet data convergence protocol PDCP used by each bearer to send the duplicate packets and/or the end SN of the packet data convergence protocol PDCP.
