[0115] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0116] PDCP duplication can be applied in dual connectivity (DC) scenarios. Figure 1 Schematic diagram of the PDCP duplication model under DC.

[0117] Figure 1 As shown, a data radio bearer (DRB) (corresponding to a PDCP entity) of the PDCP layer is transmitted separately through multiple logical channels (each logical channel corresponds to an RLC entity) in the radio link control (RLC) layer.

[0118] The function of PDCP duplication is to configure the PDCP layer of the DRB of the UE (User Equipment) on the network side to determine whether to duplicate the data of the PDCP entity and send the duplicated data through two or more different paths (such as through two different Radio Link Control (RLC) entities), and different RLC entities correspond to different logical channels. In this way, the multi-path transmission gain is used to improve transmission reliability and reduce transmission delay.

[0119] In view of the problem that conventional technologies can only support PDCP replication of two links and cannot meet the needs of PDCP replication of more than two links, an embodiment of the present invention provides an activation configuration method for link replication, which can indicate the activation or deactivation of multiple link replications through a media access control layer (Media Access Control, MAC) control element (Control Element, CE) message, and directly indicate the link information of the PDCP link that activates the DRB, so as to meet the activation or deactivation of multi-link PDCP replication and better support multiple connections.

[0120] Figure 2 FIG. 1 is a flow chart of a method for activating and configuring link replication according to an embodiment of the present invention. Figure 2 As shown, in this embodiment, the activation configuration method is applied to a base station, including:

[0121] S210, sending a media access control layer MAC control element CE message;

[0122] The MAC CE message is used for activating or deactivating at least two link duplications of a packet data convergence protocol PDCP, and the MAC CE message includes link information of the PDCP link of the activated data radio bearer DRB.

[0123] The activation configuration method of link replication described in the embodiment of the present invention, the MAC CE message is used for activation or deactivation of PDCP replication, and supports the activation or deactivation of more than two link replications, and satisfies the activation of multiple link replications by directly indicating the link information of the PDCP link that activates the DRB.

[0124] In one embodiment of the present invention, in step S210, when the first indicator bit of the MAC subheader of the MAC CE message is a preset value, the MAC CE message is used for activation or deactivation of two link duplications of PDCP;

[0125] When the second indicator bit of the MAC subheader of the MAC CE message is a preset value, the MAC CE message is used for activation or deactivation of more than two link copies of the PDCP.

[0126] Based on the above manner, the link replication activation configuration method described in the embodiment of the present invention is adopted, which can be compatible with the activation or deactivation of two link replications and can also realize the activation or deactivation of more than two link replications.

[0127] Specifically, Figure 3 As shown, in the MAC subheader, two reserved fields "field A" and "field B" of the MAC CE message used for activation or deactivation of PDCP duplication are used to indicate the activation or deactivation of two link duplications and the activation or deactivation of more than two link duplications, respectively.

[0128] For example, field A (first indicator bit) is used to indicate activation or deactivation of two link replications, and field B (second indicator bit) is used to indicate activation or deactivation of more than two links. Of course, the functions indicated by the two fields are not limited to this, and the functions can be exchanged.

[0129] Specifically, when the terminal supports only two link replications, that is, after the PDCP layer of the DRB replicates the data, the replicated data can only be sent through two paths, the sent MAC CE message indicates the activation or deactivation of the two link replications through field A. For example, field A is set to "1" to indicate the activation or deactivation of the two link replications. In addition, Figure 4 Each DRB index field (D0 to D7) of the illustrated MAC CE message indicates activation or deactivation of two link copies corresponding to each DRB.

[0130] For example, D i A value of "1" indicates that PDCP duplication of DRB i is activated. i A value of "0" indicates that PDCP duplication of DRB i is deactivated.

[0131] When the terminal supports more than two link replications, that is, after the PDCP layer of the DRB replicates the data, the replicated data can be sent through more than two paths, such as Figure 3 As shown, the sent MAC CE message, in the MAC subheader, indicates the activation or deactivation of more than two link copies through field B. For example, the field B is set to "1" to indicate the activation or deactivation of more than two link copies.

[0132] Furthermore, the link information of the PDCP link of the activated DRB is also indicated through the sent MAC CE message.

[0133] In the embodiment of the present invention, specifically, in step S210, the MAC CE message includes a DRB index field and a link information indication field corresponding to the DRB index field;

[0134] Among them, the DRB index field is used to indicate the activation or deactivation of the PDCP link replication of the DRB; the link information indication field is used for the activated link information when the DRB index field indicates the activation of the PDCP link replication of the DRB.

[0135] It should be noted that when the DRB index field indicates that the PDCP link of the DRB is deactivated, the corresponding indication of the link information indication field does not refer to the task meaning and can be any value, specifically a pre-agreed value.

[0136] Optionally, when the DRB index field is a first value, it is used to indicate activation of the PDCP link replication of the DRB; when the DRB index field is a second value, it is used to indicate deactivation of the PDCP link replication of the DRB.

[0137] Optionally, the link information indication field indicates the activated link through a preset value; wherein, there is at least one activated link, and there is a preset corresponding relationship between the preset value and the activated link.

[0138] For example, taking the case where PDCP duplication can support up to 4 links, the form of the MAC CE message sent in step S210 can be as follows: Figure 4 As shown, it includes multiple DRB index fields (D0 to D7), each DRB index field is used to indicate the activation or deactivation of at least two link copies of a DRB; further, it can also include link information indication fields (Active Leg Indicator 0 to Active Leg Indicator7) corresponding to the DRB index fields one by one, and the link information indication field indicates the activated link when the DRB indicated by the corresponding DRB index field is activated.

[0139] Optionally, the link information indication field can be located after all the DRB index fields. The one-to-one correspondence between the DRB index field and the link information indication field can be determined by pre-setting. Each link information indication field is used to indicate that the DRB indicated by the corresponding DRB index field with a pre-set correspondence is a link when it is activated.

[0140] Optionally, the DRB index field (D0 to D7) can be set to "1" (first value) to indicate the activation of the PDCP link replication corresponding to the indicated DRB; and can be set to "0" (second value) to indicate the deactivation of the PDCP link replication corresponding to the indicated DRB.

[0141] In the embodiment of the present invention, optionally, the link information indication field indicates the activated link through a preset value, wherein the preset corresponding relationship between the preset value and the activated link is as follows: Figure 5 As shown, for example, when the preset value recorded in the link information indication field is "0", it is used to indicate that the activated links are link 1 and link 2; when the preset value recorded is "8", it is used to indicate that the activated links are link 2, link 3 and link 4.

[0142] certainly, Figure 5 The preset correspondence between the preset value and the activated link described in the description is only for illustration and is not limited thereto.

[0143] Optionally, the method further comprises:

[0144] Determine, according to a preset correspondence table, a preset value corresponding to the link information activated by the target DRB;

[0145] The corresponding relationship table records corresponding preset values ​​when different links are activated.

[0146] According to the above implementation, in step S210, the sent MAC CE message indicates activation or deactivation of two link replications of PDCP by using the first indication bit of the MAC subheader as a preset value; indicates activation or deactivation of more than two link replications of PDCP by using the second indication bit of the MAC subheader as a preset value. In addition, when the MAC CE message indicates activation or deactivation of at least two link replications of PDCP, the DRB index field (D i ), when it is 1, it indicates that the PDCP duplication of DRBi is activated, and when it is 0, it indicates that the PDCP duplication of DRB i is deactivated, and the length can be 1 bit; for the link information indication field (Active Legs Indicatori) of the MAC CE message, it is used to indicate which links of DRB i are activated, the length is 4 bits, and the specific value can be as follows Figure 5 shown.

[0147] It should be noted that the DRB index field can indicate the activation or deactivation of the PDCP link of one DRB, and can also indicate the activation or deactivation of the PDCP links of at least two DRBs at the same time. The specific DRB index field is used to indicate which DRB or DRBs whose PDCP link is indicated by the DRB index field, which can be determined based on pre-configuration.

[0148] The above method can not only support the activation or deactivation of multiple link replications, but also be compatible with the activation or deactivation of two link replications.

[0149] In addition, the activation configuration method of the above-mentioned implementation mode of the embodiment of the present invention is adopted. For the sending end, on the basis of sending the above-mentioned MAC CE message, data is sent through the PDCP link activated as indicated by the MAC CE message; for the receiving end, data is received through the PDCP link activated as indicated by the MAC CE message.

[0150] Specifically, the specific implementation process of the activation configuration method according to the above implementation mode of the embodiment of the present invention is as follows: Figure 6 As shown, the steps include:

[0151] S601, the terminal receives a MAC CE message for indicating activation or deactivation of at least two link duplications of the PDCP;

[0152] S602, the terminal determines whether the first indicator bit in the MAC CE message is a preset value, such as according to Figure 2 Determine whether field A is "1". If the determination result is yes, execute step S603; if the determination result is no, execute step S604;

[0153] S603, determine the DRB index field D in the MAC CE message i is the first value or the second value, if it is the first value, execute step S605; if it is the second value, execute step S606;

[0154] S605: According to the DRB index field D in the MAC CE message i , activate the two-link replication function of DRB i, and execute S609;

[0155] S606, reporting the deactivation of the PDCP copy of DRB i to the upper layer;

[0156] S604, the terminal determines whether the second indicator bit in the MAC CE message is a preset value, such as according to Figure 2 Determine whether field B is "1". If the determination result is yes, execute step S607. If the determination result is no, end the process.

[0159] S609, the transmitting end sends data on the corresponding activated link;

[0160] S610: The receiving end receives data on the corresponding activated link.

[0161] In addition, in another implementation of the activation configuration method described in the embodiment of the present invention, in step S210, the MACCE message does not need to use a MAC subheader to indicate whether the MAC CE message is used for activation or deactivation of two link copies of PDCP, or for activation or deactivation of more than two link copies of PDCP, but directly indicates through a MAC CE message that the MAC CE message is used for activation or deactivation of at least two link copies of PDCP.

[0162] In this implementation manner, the MAC subheader of the MAC CE message is as follows: Figure 7 As shown, R is two reserved indication bits and is not used to indicate the type of link replication.

[0163] Among them, the sending end indicates the link information of the PDCP link of the activated DRB through a MAC CE message according to the needs of the service, indicating the activation of at least two link copies of the PDCP.

[0164] Specifically, in step S210, the MAC CE message includes a DRB index field and a link information indication field corresponding to the DRB index field;

[0165] Among them, the DRB index field is used to indicate the activation or deactivation of the PDCP link replication of the DRB; the link information indication field is used to indicate the link information activated corresponding to the DRB.

[0166] Optionally, when the DRB index field is a first value, it is used to indicate activation of the PDCP link replication of the DRB; when the DRB index field is a second value, it is used to indicate deactivation of the PDCP link replication of the DRB.

[0167] Optionally, the link information indication field indicates the activated link through a preset value; wherein, there is at least one activated link, and there is a preset corresponding relationship between the preset value and the activated link.

[0168] For example, taking the case where PDCP duplication can support up to 4 links, the form of the MAC CE message sent in step S210 can be as follows: Figure 8 As shown, it includes multiple DRB index fields (D0 to D7), each DRB index field is used to indicate the activation or deactivation of at least two link copies of a DRB; further, it can also include link information indication fields (Active Leg Indicator 0 to Active Leg Indicator7) corresponding to the DRB index fields one by one, and the link information indication field indicates the activated link when the DRB indicated by the corresponding DRB index field is activated.

[0169] According to the above, in Figure 8 The specific meaning of each field is as follows:

[0170] D i : Indicates the PDCP duplication activation / deactivation status of DRB i. For example, a value of "1" indicates that the PDCP duplication of DRB i is activated, and a value of "0" indicates that the PDCP duplication of DRB i is deactivated. The length is 1 bit;

[0171] Active Legs Indicator i: used to indicate which links of DRB i are activated. The length is 4 bits. The specific value can be as follows: Figure 5 As shown;

[0172] R (Reserved): Reserved field, which can be set to "0".

[0173] Alternatively, if Figure 8 As shown, the link information indication field Active Legs Indicator i corresponds to the DRB index field D i Afterwards, but not limited to this, as long as the link information indication field and the DRB index field have a one-to-one correspondence, each link information indication field indicates that the DRB indicated by the DRB index field corresponding to the preset correspondence is the activated link.

[0174] Specifically, the specific implementation process of the activation configuration method according to the above implementation mode of the embodiment of the present invention is as follows: Fig. 9 As shown, the steps include:

[0175] S901, the terminal receives a MAC CE message for indicating activation or deactivation of at least two link duplications of the PDCP;

[0176] S902, determine the DRB index field D in the MAC CE message i is the first value or the second value, if it is the first value, execute step S903; if it is the second value, execute step S906;

[0177] S903, according to the DRB index field D in the MAC CE message i The corresponding link information indicator field Active LegIndicator i determines which links of DRB i are activated;

[0178] S904, the sending end sends data on the corresponding activated link;

[0179] S905, the receiving end receives data on the corresponding activated link;

[0180] S906: Report the deactivation of the PDCP copy of DRB i to the upper layer.

[0181] By adopting the activation configuration method described in the embodiment of the present invention, it is possible to realize the activation or deactivation of multiple links of PDCP duplication in a multi-connection scenario. In addition, the MAC CE can selectively activate / deactivate certain link duplications according to actual business needs, thereby improving and enhancing the function of PDCP duplication and better supporting multiple connections.

[0187] When the second indicator bit of the MAC subheader of the MAC CE message is a preset value, the MAC CE message is used for activation or deactivation of more than two link copies of the PDCP.
