Description

Indication method for data copying transmission, terminal equipment and network equipment

Background

In Release15 URLLC, high reliability low latency traffic is considered and handled. In Rel-16, the study object was expanded, and finally, the IIoT project considers data replication transmission and multiple connectivity (Data duplication and multi-connectivity).

Release16 puts a higher demand on the data replication and transmission characteristics, and the system can implement a more flexible and efficient data replication mode, so that the following challenges or problems are brought to the prior art: the number of logical channel/radio link control (RLC, radio Link Control) entities (the number of legs supported by R16 is at least 1, including logical channel/RLC entity data = 1,2,3,4, 5.) that need to be supported for the same bearer is greater than the number of legs supported by existing data replication (the number of legs supported by R15 is 1, 2).

The data copy transmission can only support up to 2 logical channels/RLC entities, which is not matched with the requirements of more than two logical channels/RLC entities of R16, and thus a corresponding solution needs to be considered.

The communication system 100 further comprises at least one terminal device 120 located within the coverage area of the network device 110. "terminal device" as used herein includes, but is not limited to, a connection via a wireline, such as via a public-switched telephone network (Public Switched Telephone Networks, PSTN), a digital subscriber line (Digital Subscriber Line, DSL), a digital cable, a direct cable connection; and/or another data connection/network; and/or via a wireless interface, e.g., for a cellular network, a wireless local area network (Wireless Local Area Network, WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter; and/or means of the other terminal device arranged to receive/transmit communication signals; and/or internet of things (Internet of Things, ioT) devices.

Optionally, the communication system 100 may further include a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

It should be understood that a device having a communication function in a network/system in an embodiment of the present application may be referred to as a communication device. Taking the communication system 100 shown in fig. 1-1 as an example, the communication device may include the network device 110 and the terminal device 120 with communication functions, where the network device 110 and the terminal device 120 may be specific devices described above, which are not described herein again; the communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

In addition, regarding the related art, data duplication is performed at the PDCP layer, and the same PDCP PDUs are mapped to different RLC entities, respectively. The MAC needs to transmit duplicate data of different RLC entities (RLC entities) to different carriers, where the number of corresponding RLC entities may be at least one: 1,2,3,4, etc.

For CA scene, the scheme supporting data duplicate transmission (data duplicate) utilizes the duplicate data function of PDCP, so that the duplicate PDCP PDU is respectively transmitted to two RLC entities (two different logic channels), and finally, the duplicate PDCP PDU can be transmitted on different physical layer aggregation carriers, thereby achieving frequency diversity gain to improve the reliability of data transmission. Such as DRB 1 and DRB3 in fig. 1-2. :

for the DC scenario, a scheme supporting data duplicate transmission (data duplicate) utilizes the duplicate data function of PDCP to make duplicate PDCP PDUs be transmitted to two RLC entities respectively, which correspond to different MAC entities respectively. Such as DRB2 shown in fig. 1-2.

For data duplication transmission, the uplink PDCP data duplication function can be configured based on DRBs, that is, with DRB granularity, to configure duplication data transmission, and control activation or deactivation of duplication data transmission.

In the existing protocol (NR R15), for a data radio bearer configured with a copy data transmission function, the network may dynamically activate (activate) or deactivate (deactivate) the data copy transmission function of a certain data radio bearer by the MAC CE. For example, in fig. 1-3, the MAC CE includes an 8-bit Bitmap, the bits in the Bitmap correspond to different DRBs, and the activation or deactivation of the data copy data of the corresponding DRBs is indicated by the difference of the values in the bits. The prior art can only support a number of legs of up to 2, which is not matched to the requirement of more than two legs of R16. Thus, it is a problem to be solved for a corresponding solution to be considered to support the new problem introduced by R16 due to the increase in the number of legs, such as how to configure more than 2 legs, and in case more than two legs are configured, how to instruct which leg of the configuration transmits the copy data (activate), which leg of the configuration does not transmit the copy data (deactivate).

It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

Embodiment 1,

The embodiment of the invention provides an indication method for data replication and transmission, which is applied to network equipment, as shown in fig. 2, and comprises the following steps:

step 201: sending first information to terminal equipment; the first information is used for representing binding information of data copy transmission, and the objects indicated in the first information use the same copy transmission state; and/or, the first information is used for determining binding information of data copy transmission;

wherein the first information includes at least one of:

binding relationship between logical channels;

binding relationship between DRBs and/or SRBs;

binding relation between carrier wave and bearing logic channel;

binding relationship between carriers.

Wherein the object is one of a bearer, RLC (Radio Link Control, radio link layer control protocol) entity, a logical channel, and a carrier.

The use of the same copy transmission state by the above-described objects means that the copy transmission state is used by the objects indicated by the first information, or that the copy transmission state is not used by the objects.

In this embodiment, the copy transmission mode may specifically be that the logic channel is in an active state, that is, the copy transmission is in an active state; the logical channel may be in a deactivated state, i.e., a state in which no duplicate transmission is performed, without using the duplicate transmission mode.

The following describes the processing modes of the foregoing binding relationships:

the binding relationship between the logical channels includes one of:

binding relationship information of at least two logical channels;

first type mode information of at least two logical channels;

and second type mode information of at least two logical channels.

Wherein the logical channel is a configured logical channel that can be used to transmit packet data convergence protocol (PDCP, packet Data Convergence Protocol)) protocol data units (PDUs, protocol Data Unit) and/or duplicate data thereof.

It should also be noted that the logical channel may be any logical channel of the terminal device. The logical channels paired with the logical channels may belong to different Cell Groups (CG) or may belong to the same CG. And/or, the paired logical channels may correspond to different bearers, or may correspond to the same bearer.

Further, when the paired logical channels correspond to the same bearer, the logical channel is leg.

In the explanation of the les, when the data is duplicated and transmitted, the data packet of one PDCP entity may be transmitted by a plurality of RLC entities or logical channels, where one RLC entity or logical channel may be one leg. In the embodiment of the present application, it may be assumed that the number of les is n, where n is an integer greater than or equal to 1.

Specifically, at least two logical channels indicated by the binding relationship information of the at least two logical channels have the same state of using or not using copy transmission; specifically, the bound logical channels and the data copy transmission of the paired logical channels have the same activation/deactivation state, i.e. both transmit copy data or not transmit copy data.

Or,

the first type of mode information of the at least two logical channels comprises at least one mode; the state of the copy transmission used or not used for the corresponding logic channels in the same mode is the same, and the state of the copy transmission used or not used for the corresponding logic channels in different modes is the same or different. For example, there may be two modes for at least one mode, such as a first mode and a second mode, mode1 and mode 2. The data copy transmission activation/deactivation states of the logic channels in the same mode are the same, namely, the data copy transmission activation/deactivation states are the same. The data copy transmission activation/deactivation states of the logical channels of different modes may be the same or different.

Or alternatively

The second type mode information of the at least two logic channels comprises at least one full mode and a selection mode; the corresponding logic channels in the same full mode are identical in state of copy transmission or copy transmission not, and the corresponding logic channels in different full modes are identical in state of copy transmission or copy transmission not; and the use copy transmission or the non-use copy transmission state of the logic channel corresponding to the selection mode is respectively indicated. Wherein the full mode, selects the mode select mode. The full mode represents a pairing group of logical channels with other logical channels, the group of logical channels uses a common bit to indicate whether to transmit duplicate data, and the select mode represents a logical channel unpaired group, the logical channels require a separate bit to indicate whether to transmit duplicate data.

It should be noted that the usage or non-usage of the duplicate transmission status of the logical channels between each full mode may be the same or different, e.g., the usage or non-usage of the duplicate transmission status of the logical channels of the first full mode and the second full mode may be different; the first full mode and the third full mode are the same in logical channel with or without duplicate transmission states.

It should be further noted that, the first information is used to determine binding information of data replication transmission, which means that the terminal device can determine the binding information between objects through the related information indicated in the first information. For example, when the first information indicates that the logical channel 1 is a bonded logical channel, or that the logical channel 1 is a full-mode channel, the

logical channels

3 and 4 also indicate that the logical channel is a full-mode channel; that is, the terminal device may determine that the

logical channels

1, 3, 4 have the bonding relationship based on the first information for the

logical channels

1, 3, 4. Other granularities are also the same processing manner, for example, for a DRB or a carrier, a binding identifier may be set for the DRB or the carrier, and when another SRB and/or DRB are also set with a corresponding binding identifier, a binding relationship is provided between the data resource bearer (DRB, data Resource Bearer) and the signaling resource bearer (SRB, signal Resource Bearer) and/or DRB; and will not be described in detail here.

By adopting the mode, under the condition of flexibly and effectively supporting the indication of data replication, bit positions required in the indication information are reduced, short/simple bit indication is used as much as possible, air interface signaling overhead caused by the introduction of a plurality of bit indications is reduced as much as possible, and the processing complexity of terminal equipment and a base station is reduced.

A first treatment mode,

The specific flow of this processing mode is shown in fig. 3:

the network side may specifically determine whether to use the data replication transmission mode and the relevant configuration information of the data replication transmission mode for the base station. The first information is a mandatory or optional configuration.

The network side can be a base station, determines a used data copying transmission mode and informs the terminal equipment of configuration information and first information corresponding to the data copying mode; the first information is used to indicate a bonding relationship between logical channels. Specifically, the bound logical channels and the data copy transmission of the paired logical channels have the same activation/deactivation state, i.e. both transmit copy data or not transmit copy data.

Further, the present processing method includes sub-scheme 1:

the sending the first information to the terminal equipment includes:

determining at least two logical channels having the same state of using or not using duplicate transmissions; transmitting configuration information corresponding to the at least two logic channels to terminal equipment, wherein the configuration information is used for indicating the first information;

wherein the configuration information includes binding information of the logical channel; and when the binding information indicated in the configuration information is true, characterizing the logic channel as one of at least two logic channels with the same copy transmission using or no copy transmission state.

That is, the binding information is indicated in a configuration message corresponding to a logical channel that the network-side base station transmits to the terminal device. If the bonding indication information is true (tube), it represents logical channel bonding. Further, the terminal device may set all logical channels with binding indication information of more as a group. By indicating whether one of the logical channels transmits duplicate data (active/inactive), i.e. whether all logical channels of the group transmit duplicate data (active/inactive).

In this sub-scheme, the network side may indicate to the terminal device the state of using or not using copy transmission of the logical channel through one of a media access Control (MAC, media Access Control) Control Element (CE), a radio resource Control (RRC, radio Resource Control) message, and DownLink Control information (DCI, downLink Control Information); wherein, one of the MAC CE, the RRC message and the DCI carries at least one of the following information: logical channel identification, CG identification of cell group corresponding to logical channel.

Another way of sending the indication may be: the configuration message further includes: group identification to which the logical channels are bound; the method further comprises the steps of: indicating the use copy transmission or non-use copy transmission state of the logic channel to the terminal equipment through one of MAC CE, RRC message and DCI; wherein, one of the MAC CE, the RRC message and the DCI carries at least one of a group identifier bound by a logic channel and a logic channel identifier, and a cell group CG identifier corresponding to the logic channel.

That is, the bound group identity is indicated at the same time in a configuration message sent to the terminal device at the network side. And then, at least one of the group identifier and the logic channel identifier which are bound is carried in the message indicating update, such as the MAC CE, and the cell group CG identifier corresponding to the logic channel.

For example, referring to fig. 4, if the Logical Channel (LC) 1 of DRB1 and the LC4 of DRB2 and the LC5 of DRB3 are configured, the binding indication information of the Logical Channel (LC) 1 of DRB1 and the LC4 of DRB2 and the LC5 of DRB3 is set to be Ture, boundflag=1.

The new Information Element (IE) boundFlag may be formatted as follows boundFlag-R16 BOOLEAN OPTIONAL, -Need R. Specific:

the processing mode may further include sub-scheme 2:

the sending the first information to the terminal equipment includes:

determining at least two logical channels having the same activation or deactivation state;

transmitting configuration information corresponding to a first logical channel in the at least two logical channels to terminal equipment; the configuration information comprises an identifier of a logic channel bound with the first logic channel and/or a CG identifier of the logic channel bound with the first logic channel.

That is, in the configuration message corresponding to the logical channel, the logical channel identifier bound thereto and/or the CG identifier to which the bound logical channel belongs are indicated. The bonded logical channels are a group, indicating whether one of the logical channels transmits duplicate data (active/inactive), i.e., indicating whether all logical channels of the group transmit duplicate data (active/inactive).

The method further comprises the steps of: indicating the use copy transmission or non-use copy transmission state of the logic channel to the terminal equipment through one of MAC CE, RRC message and DCI; wherein, one of the MAC CE, the RRC message and the DCI carries at least one of the following: logical channels, CG identification of cell group to which the logical channels belong.

For example, configuring Logical Channel (LC) 1 of DRB1, and LC4 of DRB2, LC5 of DRB3, can carry boundLogicalChannels IE and CG-Idendity when configuring Logical Channel (LC) 1 of DRB 1.

For example, a new number IE, boundLogicalChannel is used to configure the binding logical channel identifier corresponding to the logical channel and the cell group identifier to which the binding logical channel identifier belongs. The binding logical channel is specifically indicated by the IE, and may include a logical channel identifier (logicalchannel identifier) and a cell group identifier (CG-identifier), for example, may include: "boundLogicalchannelist-r 16 SEQUENCE (SIZE (1..maxlc-ID-1)) OF boundLogicalChannel OPTIONAL, -Need R boundLogicalChannel: =sequence {

LogicalChannelIdentity LogicalChannelIdentity,OPTIONAL,--Need R

CG-identity CellGroupId OPTIONAL,--Need R”

A list of logical channels for identifying the binding, an identification of the logical channels, and a cell group identification.

The method comprises the following steps:

The first information is carried by an RRC reconfiguration message. That is, the base station informs all data copy transmission configuration information and the first information through the RRC reconfiguration message.

Optionally, the base station adds an IE in LogicalChannelConfig IE in RRC reconfiguration IE for notifying the first information. The advantage of reusing RRC reconfiguration messages is that existing messages and procedures are reused as much as possible, reducing terminal equipment complexity. Specific IE formats are referred to in the foregoing description and will not be described here.

For the subsequent processing of the foregoing two sub-schemes, still referring to fig. 3, the terminal device receives an RRC message from the base station (i.e., the network side), configures the RLC entity according to the first information in the RRC message, and confirms the pairing information and/or the paired logical channel according to the first information. The terminal device then transmits in accordance with the initial copy data transmission. The initial copy data transmission mode may be included in the configuration information sent from the network side, or may be a default initial copy data transmission mode of the terminal device, or may be activated or deactivated, that is, a copy transmission mode or a mode that does not use copy transmission. Further, in the initial transmission mode configuration, the RLC entity used may be configured to be activated or deactivated.

When the base station judges that the data replication mode is required to be changed, and when the data replication transmission is activated/deactivated, the base station instructs the terminal equipment to change the state of replication data transmission into activation or deactivation through the special information. The dedicated information may be MAC CE, RRC, DCI signaling.

When the terminal equipment receives a change indication message of the data replication mode from the base station, for example, when the terminal equipment is instructed to activate/deactivate the correspondingly carried data replication transmission by the MAC CE, the terminal equipment determines to activate or deactivate according to the corresponding bit information in the MAC CE, and then performs data transmission according to the updated data replication transmission activation/deactivation state.

The formats of MAC CE, RRC, DCI may be illustrated as shown in fig. 5 and 6, taking MAC CE as an example, and a new LCID may be introduced into a MAC CE subheader to indicate a new format for duplicating data transmission activation/deactivation signaling. Wherein, A/D: representing whether the corresponding logical channel transmits duplicate data. Logicalchannelidity: representing the indicated logical channel identity. CG-ID: cell Group identity representing indicated logical channel home.

Sub-scheme 3:

indicating a state of using or not using the duplicate transmission of the logical channel, that is, an activated or deactivated state, through at least one mode; the present solution is illustrated by taking two modes as an example, which are a first mode and a second mode, specifically:

And indicating the copy transmission state or the copy transmission state not used for the logic channel corresponding to the first mode to the terminal equipment through one of the MAC CE, the RRC message and the DCI, and/or indicating the copy transmission state or the copy transmission state not used for the logic channel corresponding to the second mode.

Specifically, the first information may be mode type information of a logical channel, including mode 1 and mode 2. The data copy transmission activation/deactivation states of the logic channels in the same mode are the same, namely, the data copy transmission activation/deactivation states are the same.

Specifically, the indication bits used are different in different modes.

For example: configuring Logical Channel (LC) 1 of DRB1 and LC4 of DRB2, LC5 of DRB3 being 1 and the other logical channels being 2, it is possible to carry bound mode when configuring Logical Channel (LC) 1 of DRB1, and determine which mode is based on the IE, e.g. the rrc configuration, e.g. IE bound mode, for configuring the mode information of the logical channel binding, which may be "bound mode-R16 ENUMERATED {1,2,3,4} operation, -new R" for indicating binding mode. See in particular the following:

and the MAC CE, the RRC message and the DCI indicate the copy transmission using or not using state of the logic channel corresponding to the first mode through different rows, and/or indicate the copy transmission using or not using state of the logic channel corresponding to the second mode. It should be understood that the first row and the second row may or may not be adjacent, and of course, the first row and the second row may be from top to bottom or from bottom to top.

For example, referring to fig. 7, the first row represents whether the logical channel of mode1 transmits duplicate data, and the second row represents whether the logical channel of mode2 transmits duplicate data.

Sub-scheme 4:

and indicating the copy transmission state or the copy transmission state not used for the logic channel corresponding to the full mode to the terminal equipment through one of the MAC CE, the RRC message and the DCI, and/or selecting the copy transmission state or the copy transmission state not used for the logic channel corresponding to the mode.

Specifically, the first information may be mode information of a logical channel, including full mode, select mode. Wherein full mode represents pairing of logical channels with other logical channels to form a group, the group of logical channels employing a common bit to indicate whether to transmit duplicate data, and select mode represents a logical channel unpaired group, the logical channels requiring a separate bit to indicate whether to transmit duplicate data.

If the logical channels are configured as full mode, the activation/deactivation states of the paired logical channels are the same, or the paired logical channels are all activated, or the paired logical channels are all deactivated.

If the logical channel is configured as a select mode, representing no pairing, a separate bit is required to indicate whether duplicate data is to be transmitted.

For example: and determining the final supportable RLC entity activation mode according to the mode information. For example, 4 logical channels/RLC entities are configured, and the modes of

channels

0,1,2,3 are full, select, full, select, respectively, and the combination of all RLC activations supported in this way is several (0 represents the corresponding RLC entity activation, 1 represents the corresponding RLC entity deactivation, and the order is RLC entity 0, RLC entity 1, RLC entity 2, RLC entity 3): (0, 0), (1, 0,1, 0), (1, 0), (1, 0, 1), (1, 1) for example, these 5 combinations, may be indicated by different values represented by 3 bits in the corresponding row of the select mode. Alternatively, the leg combining mode or the combining mode of all RLC activation may be notified to the terminal device by the base station, or may be predefined.

And at least one bit in the first row indicates the copy transmission state or the copy transmission state not used by the logic channel corresponding to the full mode, and/or at least one bit in the second row indicates the copy transmission state or the copy transmission state not used by the logic channel corresponding to the selection mode. For example, referring to fig. 7 and 8, the first row in fig. 7 represents whether the logical channel of full mode transmits the copy data, and the second row represents whether the logical channel of select mode transmits the copy data; alternatively, as shown in FIG. 8, the A/D in the information: representing whether the corresponding logical channel transmits duplicate data; logicalchannelidity: representing the indicated logical channel identity; CG-ID: a Cell Group identity representing the indicated logical channel assignment; index: representing which of the corresponding indications is available for transmitting the logical channel combination of the duplicate data.

A second treatment mode,

The DRB indicated in the binding relation between the DRB and/or the SRB and the SRB have the same data replication transmission activation or data replication transmission deactivation state;

or, the SRB indicated in the binding relationship between the DRBs and/or SRBs, and the SRB and/or the DRB have the same data replication transmission activation or data replication transmission deactivation state.

Specifically, the bound SRBs and/or DRBs are the same as their paired DRBs and/or SRBs in the data copy transmission activation/deactivation state, i.e., both transmit copy data or no copy data.

Based on the above processing mode, under the condition of supporting the indication of data duplex flexibly and effectively, bit positions required in the indication information are reduced, short/simple bit indication is used as much as possible, air interface signaling overhead caused by the introduction of a plurality of bit indications is reduced as much as possible, and the processing complexity of terminal equipment and a base station is reduced.

The method comprises the following specific steps:

the network side, such as a base station, determines to use a data replication transmission mode, and notifies the terminal device of configuration information corresponding to the data replication mode, and first information, which is used to indicate that the first information is a binding relationship between bearers (DRBs and/or SRBs). Specifically, the bound bearer and the data copy transmission of the paired bearer have the same activation/deactivation state, i.e. both the copy data and the non-copy data are transmitted.

For example, referring to fig. 4, DRB1 and DRB2 binding is configured, representing that if the use of DRB is indicated for duplicate data transmission, DRB2 also employs the same duplicate data transmission at the same time.

The RRC IE is as follows: an IE, boundDRBs, is added, for example, in RadioBearerConfig IE in RRC reconfiguration IE, for configuring the identity of the bearer to which this bearer is bound. For example, "" boundSRBs-R16 SEQUENCE (SIZE (1..maxDBB-1)) OF SRB-Identity OPTIONAL, - - -Need R "and/or" boundDRBs-R16 SEQUENCE (SIZE (1..maxDBB-1)) OF DRB-Identity OPTIONAL, - - -Need R "are used to indicate information OF the bound DRB, respectively. Specifically, for example:

the base station informs all the data copy transmission configuration information and the first information through the RRC reconfiguration message.

Optionally, the base station adds an IE in LogicalChannelConfig IE in RRC reconfiguration IE for notifying the first information. The advantage of reusing RRC reconfiguration messages is that existing messages and procedures are reused as much as possible, reducing terminal equipment complexity. The specific IE format is referred to in the foregoing description and will not be described in detail.

The terminal equipment receives the RRC message from the base station, configures the RLC entity, and confirms the pairing information and the paired bearing information according to the first information. The terminal device then transmits in accordance with the initial copy data transmission.

The method further comprises the steps of:

indicating a change instruction of data copy transmission to the terminal equipment through one of MAC CE, RRC message and DCI;

and one of the MAC CE, the RRC message and the DCI carries the identification of the DRB or the SRB, or carries the identification of the DRB or the SRB and an indication of whether the logical channel corresponding to the DRB or the SRB transmits the copy data.

The MAC CE may be in the following format:

optionally, a new LCID is introduced in the MAC CE sub-header for indicating a new format of the duplicate data transmission activation/deactivation signaling. See, for example, fig. 9, where a/D: representing whether the corresponding logical channel transmits duplicate data; DRB-identity: representing the indicated DRB identity.

A third treatment mode,

And the binding relation between the carrier and the loaded logical channel is used for determining whether the loaded logical channel transmits the copy data by indicating the copy transmission state of the carrier or the copy transmission state of the carrier.

That is, the first information is bonding information between the carrier and the logical channel of the bearer. Specifically, a manner of activation/deactivation based on a carrier may be used to indicate whether a logical channel of a corresponding bearer transmits duplicate data. Here, when the logical channel indicated by the carrier transmits the copy data, the bearers corresponding to the logical channel may or may not be the same bearer.

The method comprises the following specific steps:

the base station determines to use a data replication transmission mode, and informs the terminal device of configuration information corresponding to the data replication mode and first information, wherein the first information is used for indicating that the first information is a binding relation between a carrier and a Logic Channel (LC). Specifically, the carrier wave and the data copy transmission of the logic channel have the same activation/deactivation state, namely, both the transmission of the copy data and the non-transmission of the copy data.

For example, referring to fig. 4, LC1 of DRB1 and LC1 of DRB2 are transmitted over carrier 1, indicating whether the carrier uses duplicate data transmission, representing whether LC1 of DRB1 and LC1 of DRB2 employ duplicate data transmission. Determining a binding relationship between a carrier and a logical channel according to IE allowedServingCells

The terminal equipment receives the RRC message from the base station, configures the RLC entity, and confirms the relation information of the logic channel and the carrier according to the first information. The terminal device then transmits in accordance with the initial copy data transmission.

The method further comprises the steps of:

the MAC CE, the RRC message and the DCI carry at least one of the following: the identification of the carrier, the identification of the cell group to which the carrier belongs, and an indication of whether the logical channel to which the carrier corresponds transmits duplicate data.

In the MAC CE sub-header, a new LCID is introduced for indicating a new format of the duplicate data transmission activation/deactivation signaling. For example, referring to FIG. 10, A/D: representing whether the corresponding logical channel transmits duplicate data; servCellIndex: representing an indicated serving cell (carrier) identity; CG-ID, representing the cell group identity to which the indicated serving cell (carrier) belongs.

A fourth treatment mode,

And the binding relation between the carriers is used for indicating that at least two carriers with the binding relation have the same state of using copy transmission or not using copy transmission.

That is, the first information is carrier-to-carrier bonding information. In particular, the data copy transmission activation/deactivation status of the indication carrier and the carrier paired therewith may be the same, i.e., both the copy data and the copy data are transmitted or not transmitted.

The method comprises the following specific steps:

the base station determines a data copying transmission mode, and informs the terminal equipment of configuration information corresponding to the data copying mode and first information, wherein the first information is used for indicating that the first information is a binding relation between carriers. Specifically, the carrier wave and the data copy transmission of the carrier wave have the same activation/deactivation state, namely, both the transmission of the copy data and the non-transmission of the copy data. Further, according to the carrier information which is allowed to be used by the logic channel, the binding relation between the carrier and the logic channel is determined. Specifically, the carrier wave and the data copy transmission of the logic channel have the same activation/deactivation state, namely, both the transmission of the copy data and the non-transmission of the copy data. Alternatively, a combination of the third processing method may be used, where the first information carries a binding relationship between the carrier and the carrier, and between the carrier and the LC.

For example, carrier 1 and carrier 2 are bonded, and carrier 2 uses duplicate data transmission at the same time by indicating whether carrier 1 uses duplicate data transmission. Accordingly, the logical channel or RLC entity transmitting the duplicate data using the carrier employs the same data transmission scheme (active/inactive)

Optionally, the base station adds IE, boundServingCells to CellGroupConfig IE in RRC reconfiguration IE to indicate the carrier bound to this carrier. Such as boundServingCells-r16 SEQUENCE (SIZE (1. MaxNrofServingCells-1)) OF ServCellIndex OPTIONAL, -PDCP-ca duplex. The method comprises the following steps:

the terminal equipment receives the RRC message from the base station, configures the RLC entity, and confirms the relation information between the carriers according to the first information. The terminal device then transmits in accordance with the initial copy data transmission.

The format of the MAC CE, the RRC message and the DCI is the same as the third processing mode, specifically, a change instruction of data copy transmission is indicated to the terminal equipment through one of the MAC CE, the RRC message and the DCI; the MAC CE, the RRC message and the DCI carry at least one of the following: the identification of the carrier, the identification of the cell group to which the carrier belongs, and an indication of whether the logical channel to which the carrier corresponds transmits duplicate data.

Finally, the description is made for the formats of MAC CE, RRC message, DCI, since the prior art can only support data copy transmission with a number of legs of at most 2, which is not matched to the requirement of R16 for more than two legs. And only one bit of activation/deactivation indication mode is supported, the method can only realize that all the leg transmits the copy data (activation), or that all the leg does not transmit the copy data (deactivation, only the primary leg transmits PDCP PDU original) indication result. However, once the base station wants to indicate different activation/deactivation actions (pass or fail) to different leg, respectively, no indication can be made. Therefore, the embodiment of the invention introduces a new special information indication mode, such as introducing a new MAC CE, RRC message, DCI format, and each leg (logical channel) corresponding to each bearer uses a 1bit indication to indicate whether the leg transmits copy data (activation/deactivation).

The new MAC CE, RRC message, DCI, one of its alternative formats is as follows:

different columns correspond to different DRB IDs, or carrier identifications, or cell group identifications to which carriers belong, and the corresponding modes are consistent with the existing protocol; different rows correspond to different RLC entities associated with a certain DRB, or carrier identification, or cell group identification to which the carrier belongs; the value in the bit represents whether duplicate data is transmitted using the RLC entity; the following description will be made with DRB:

The number of rows=max { is any one bearer configuration, RLC entity/logical channel number for duplication data output }, for example, the number of RLC entities configured for DRB0 is 4, the number of RLC entities configured for DRB3 is 8, and the number of rows of the MAC CE is 8.

Or, the number of lines = limited RLC entity/logical channel number for transmitting duplicate data, which may be a preset value or an RRC configured value.

For example, the MCG has 2 DRBs configured with copy data transfer functions, and DRB IDs of 0, 3, 5, and 7, respectively;

the format of the MAC CE is 4 bytes, and these DRBs are corresponding to each other in ascending order of DRB IDs from column 1 to column 4 at a time. For example, columns D0, D1, D2, D3 correspond to

DRB IDs

0, 3, 5, 7, respectively. The different rows in each column indicate which RLC entities are employed to transmit duplicate data, and in particular, up to 4 RLC entities may be indicated to transmit duplicate data in this example. Ordered in the order MCG first and SCG then, in each CG in ascending or descending order of logical channel IDs. Alternatively, the order may be in order of SCG followed by MCG, with logical channel IDs ascending or descending in each CG. For example, for each row of DRB0,

RLC entities

0, 1, 2, 3 are represented from top to bottom, respectively.

Referring to fig. 11, after determining and executing data copy transmission configuration according to the first information, the terminal device receives an indication sent by the network base station through the new format MAC CE, and determines whether each leg transmits copy data according to the indication of the MAC CE.
