Description

Technical Field

[0001] The present invention relates to wireless communication technology, and in particular to a method for controlling a copy data transmission function, a terminal and a computer storage medium. Background Art

[0002] In the dual-connectivity architecture, replicated data transmission uses a split data radio bearer (DRB) protocol architecture. Two identical copies of data are sent to the terminal by the master cell group (MCG) and the secondary cell group (SCG), respectively. The terminal discards one of the two identical copies of data and transmits the other to the upper layer.

[0003] The duplicate data transmission function is activated or deactivated based on a bitmap indication. In the 5G system, under the dual-connectivity architecture, since the MCG and SCG can respectively send MAC CEs containing bitmaps to the terminal, how does the terminal select the bitmap corresponding to the MCG or SCG, and how does it determine the correspondence between the bits in the bitmap and the split DRB with duplicate data transmission function, thereby controlling the activation / deactivation of the duplicate data transmission function of the split DRB?

[0065] Before describing in detail the method for controlling the duplicate data transmission function according to an embodiment of the present invention, the protocol stack architecture of the dual-connection architecture is first described. Figure 1a Schematic diagram of the downlink protocol stack architecture of the dual-connection system; Figure 1b The uplink protocol stack architecture diagram of the dual connection system is shown in FIG. Figure 1a As shown in the figure, the Packet Data Convergence Protocol (PDCP) entity is located in a certain cell group (CG), and the CG is called the anchor CG. The PDCP entity copies the PDCP protocol data unit (PDU) into two identical copies, for example, one is a PDCP PDU and the other is a duplicated PDCP PDU. The PDCP PDU and the Duplicated PDCP PDU pass through the RLC and MAC of different CGs (such as MCG and SCG), and then pass through the air interface to reach the corresponding MAC entity and RLC entity of the terminal, and finally converge to the PDCP entity of the terminal. The PDCP entity detects that the two PDCP PDUs are the same duplicate versions, that is, it discards one of them and transmits the other to the higher-level entity. On the contrary, if Figure 1b As shown, the PDCP entity of the terminal copies the PDCP PDU into two identical copies, for example, one is the PDCP PDU and the other is the Duplicated PDCP PDU. The PDCP PDU and the Duplicated PDCP PDU pass through the RLC and MAC corresponding to different CGs (such as MCG and SCG), and then pass through the air interface to reach the MAC entity and RLC entity of the MCG and SCG respectively, and finally converge at the PDCP entity as the anchor CG.

[0066] like Figure 1a and Figure 1bAs shown, the bearer that connects the PDCP entity to the two RLCs and MAC respectively is called a splitbearer. If the PDCP entity is located in the MCG, the bearer can be called an MCG Split Bearer. If the PDCP entity is located in the SCG, the bearer can be called an SCG Split Bearer.

[0067] In the 5G system, for bearers configured with a duplicate data transmission function, the duplicate data transmission function of a bearer can be dynamically activated (activated) or deactivated (de-activated) through MAC CE. For dual-connection scenarios, MCG and SCG can respectively send MAC CE to activate or deactivate the duplicate data transmission function of a split bearer of the terminal. Among them, MAC CE may include a bit map, that is, different bits correspond to different bearers. The value of the bit represents the activation or deactivation of the duplicate data transmission function of the corresponding bearer. However, in a dual-connection scenario, the terminal cannot determine the correspondence between the bit map of MCG or SCG and the bearer. Based on this, the following embodiments of the present invention are proposed.

[0068] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0069] Example 1

[0070] An embodiment of the present invention provides a method for controlling a copy data transmission function. Figure 2 FIG. 1 is a flow chart of a method for controlling a copy data transmission function according to an embodiment of the present invention; FIG. Figure 2 As shown, the method includes:

[0071] Step 101: The terminal determines the bit positions in the received bitmap according to the indication information corresponding to the DRB configuration and / or the preset rules; the bitmap is one of the two received bitmaps.

[0072] Step 102: The terminal determines activation / deactivation of the duplicate data transmission function of the DRB based on the indication of the bit.

[0073] In an embodiment of the present invention, before the terminal determines the bit position in the received bit map according to the indication information corresponding to the DRB configuration and / or preset rules, the method also includes: the terminal receives the bit maps of the MAC entity corresponding to the MCG and the MAC entity corresponding to the SCG respectively.

[0074] Among them, the terminal receives the bit maps corresponding to the MAC entity of MCG and the MAC entity corresponding to SCG respectively, including: the first MAC entity of the terminal receives the first MAC control element MAC CE corresponding to the MAC entity of MCG, and obtains the bit map in the first MAC CE; the second MAC entity of the terminal receives the second MACCE corresponding to the MAC entity of SCG, and obtains the bit map in the second MAC CE.

[0075] Accordingly, the terminal determines the activation / deactivation of the duplicate data transmission function of the DRB based on the indication of the bit, including: the PDCP entity of the terminal determines the activation / deactivation of the duplicate data transmission function of the DRB based on the value of the bit; the PDCP entity corresponds to the DRB. It can be understood that for a DRB configured with the duplicate data transmission function, the bit in the bitmap in the MAC CE received by the MAC entity is determined, the value of the bit is indicated to the PDCP entity corresponding to the DRB, and the PDCP entity determines the activation / deactivation of the duplicate data transmission function according to the value of the bit.

[0076] In this embodiment, before the terminal determines the bit positions in the received bitmap according to the indication information and / or preset rules corresponding to the DRB configuration, the method further includes: the terminal obtaining signaling sent by a network device, and determining the indication information and / or preset rules corresponding to the DRB based on the signaling. The signaling may specifically be Radio Resource Control (RRC) signaling, that is, the terminal may obtain the indication information and / or preset rules based on the semi-static configuration of the network device.

[0077] The embodiments of the present invention are applicable to two scenarios. In the first application scenario, the DRB is a split DRB configured with a replicated data transmission function. In the second application scenario, the DRB is a non-split DRB configured with a replicated data transmission function.

[0078] In the first application scenario, as the first implementation method, the indication information includes an indication identifier and an indication bit; the terminal determines the bit position in the received bit map based on the indication information corresponding to the DRB configuration, including: the terminal selects the bit map corresponding to the MCG or SCG reception for the DRB based on the indication identifier; the terminal determines the bit position in the bit map based on the indication bit.

[0079] Here, the indicator represents a selection rule for determining the selection of one of the two bitmaps, that is, the indicator is used to instruct the terminal to select the bitmap corresponding to MCG or the bitmap corresponding to SCG. In actual applications, the indicator can be a 0 / 1 identifier, 0 and 1 correspond to MCG and SCG respectively. For example, when the indicator is configured as a 0 identifier, the bitmap corresponding to MCG is selected, and when the indicator is configured as a 1, the bitmap corresponding to SCG is selected. Of course, it can also be the other way around, 0 identifier corresponds to MCG, and 1 identifier corresponds to SCG, which is not limited in this embodiment.

[0080] The indicator bit may indicate any bit in the bitmap; when the bitmap includes 8 bits, the indicator bit may include 3 bits, for example, 000 corresponds to the first bit in the bitmap, 001 corresponds to the second bit in the bitmap, and so on. The terminal then determines the bit in the bitmap based on the indicator bit, and determines activation / deactivation of the duplicate data transmission function of the DRB based on the value of the bit.

[0081] As a second implementation manner, the indication information includes an indication identifier; the terminal determines the bit position in the received bit map based on the indication information corresponding to the DRB configuration and the preset rules, including: the terminal selects the bit map corresponding to the MCG or SCG received for the DRB based on the indication identifier; the terminal determines the bit position in the bit map based on the identifier of the DRB.

[0082] Referring to the description of the indicator in the first embodiment, the indicator represents a selection rule for determining the selection of one of the two bitmaps, that is, the indicator is used to instruct the terminal to select the bitmap corresponding to the MCG or the bitmap corresponding to the SCG.

[0083] As an embodiment, the terminal determines the bit position in the bit map based on the identifier of the DRB, including: the terminal sorts the identifier of the DRB with the identifiers corresponding to other DRBs, and determines the bit position in the bit map according to the position of the identifier of the DRB in the sort; wherein, the sorting includes ascending sorting or descending sorting.

[0084] The identifier of the DRB is specifically a DRB ID. The DRB ID of each DRB is fixed and non-repeating. The terminal then sorts all DRB IDs, and the sorting rules can be in ascending order or descending order. For example, if the DRB ID is 3, and the IDs of other DRBs include 1, 5, 7, and 9, then the DRB ID is in the second position in the ascending order of all DRB IDs, and accordingly, the second bit in the bitmap is determined; and the DRB ID is in the third position in the descending order of all DRB IDs, and accordingly, the third bit in the bitmap is determined.

[0085] As another implementation, the terminal may also determine the bit in the bitmap based on the DRB identifier. This implementation is applied to a scenario where the number of bits in the bitmap is greater than or equal to the number of DRBs of the terminal and the DRB ID is not greater than 8. For example, if the DRB ID is 3, the third bit in the bitmap can be determined.

[0086] In the second application scenario, as the first implementation method, the indication information includes an indication bit; the terminal determines the bit position in the received bit map according to the indication information corresponding to the DRB configuration, including: the terminal selects the bit map corresponding to the MCG or SCG reception for the DRB; the terminal determines the bit position in the bit map based on the indication bit.

[0087] In this application scenario, the terminal does not need to select the bitmap corresponding to the MCG or SCG reception through the indicator, but can directly select the bitmap corresponding to the MCG or SCG reception for the DRB. Furthermore, the indicator bit can indicate any bit in the bitmap; when the bitmap includes 8 bits, the indicator bit can include 3 bits, such as 000 corresponding to the first bit in the bitmap, 001 corresponding to the second bit in the bitmap, and so on. The terminal then determines the bit in the bitmap based on the indicator bit, and determines the activation / deactivation of the DRB's duplicate data transmission function based on the value of the bit.

[0088] As a second implementation manner, the terminal determines the bit positions in the received bitmap according to preset rules, including: the terminal selects the bitmap corresponding to the MCG or SCG reception for the DRB; the terminal determines the bit positions in the bitmap based on the identifier of the DRB.

[0089] In this application scenario, the terminal does not need to select the bitmap corresponding to the MCG or SCG reception through an indication identifier, but can directly select the bitmap corresponding to the MCG or SCG reception for the DRB.

[0090] In this embodiment, the terminal determines the bit position in the bit map based on the identifier of the DRB, including: the terminal sorts the identifier of the DRB with the identifiers corresponding to other DRBs, and determines the bit position in the bit map according to the position of the identifier of the DRB in the sort; wherein, the sorting includes ascending sorting or descending sorting.

[0091] The identifier of the DRB is specifically a DRB ID. The DRB ID of each DRB is fixed and non-repeating. The terminal then sorts all DRB IDs, and the sorting rules can be in ascending order or descending order. For example, if the DRB ID is 3, and the IDs of other DRBs include 1, 5, 7, and 9, then the DRB ID is in the second position in the ascending order of all DRB IDs, and accordingly, the second bit in the bitmap is determined; and the DRB ID is in the third position in the descending order of all DRB IDs, and accordingly, the third bit in the bitmap is determined.

[0092] As another implementation, the terminal may also determine the bit in the bitmap based on the DRB identifier. This implementation is applied to a scenario where the number of bits in the bitmap is greater than or equal to the number of DRBs of the terminal and the DRB ID is not greater than 8. For example, if the DRB ID is 3, the third bit in the bitmap can be determined.

[0093] In this application scenario, the indication bits in the indication information corresponding to the non-split DRB configuration of different cell groups are the same or different. For example, the indication bits in the corresponding indication information of non-split bearers belonging to different CGs can all be configured as 000.

[0094] In this embodiment, the indicator is only configured in the indication information corresponding to the split DRB with the replicated data transmission function, indicating whether the split DRB is controlled by the MCG MAC CE or the SCG MAC CE. For non-split DRBs, the corresponding indication information does not have an indicator.

[0095] In this embodiment, for non-split bearers, whether for MCG or SCG non-split bearers, the duplicate data transmission function is only controlled based on the MAC CE received by the MAC entity corresponding to the MCG or the MAC CE received by the MAC entity corresponding to the SCG.

[0096] By adopting the technical solution of the embodiment of the present invention, the bit positions in the bitmap are determined by the indication information and / or preset rules corresponding to the DRB configuration. In a dual-connection scenario, the bitmap corresponding to the MCG or SCG can be determined according to the indication information, so that the activation / deactivation of the DRB's duplicate data transmission function can be achieved based on the indication of the bit positions in the bitmap.

[0097] The following describes in detail the method for controlling the copy data transmission function according to the embodiment of the present invention in conjunction with specific application scenarios.

[0098] Scene 1

[0099] In this scenario, the terminal determines the indication identifier and indication bit of the DRB based on the signaling of the network device, and determines the MCG MAC CE corresponding to the MCG received for the DRB based on the indication identifier.

[0100] The terminal receives a MAC CE for controlling activation / deactivation of the duplicate data transmission function from the MCG MAC entity.

[0101] The terminal first determines which DRBs are controlled by the MCG MAC entity, such as Figure 3 As shown, it can be determined first that the non-split DRB with DRB ID=1 is controlled by the MCG MAC CE, and at the same time, it can be determined that the split DRB with DRB ID=3 is controlled by the MCG MAC CE by checking the 0 / 1 indicator configured in the split DRB.

[0102] The terminal then checks the indicator bits in the two DRBs and determines that the non-split DRB with DRB ID=1 is controlled by the first bit in the bitmap, and DRB ID=3 is controlled by the second bit in the bitmap, and the remaining bits in the bitmap are invalid bits.

[0103] The MAC entity of the terminal indicates the bit value of the first bit in the bit map to the PDCP entity of the non-split DRB with DRB ID = 1, and the MAC entity of the terminal indicates the bit value of the second bit in the bit map to the PDCP entity of the split DRB with DRB ID = 3; the corresponding PDCP entity decides to activate / deactivate the copy data transmission function of the corresponding DRB based on the indicated bit value.

[0104] Scene 2

[0105] In this scenario, the terminal determines the DRB indication identifier based on the signaling of the network device, and determines to select the MCG MAC CE corresponding to the MCG received for the split DRB based on the indication identifier.

[0106] The terminal receives a MAC CE for controlling activation / deactivation of the duplicate data transmission function from the MCG MAC entity.

[0107] The terminal first determines which DRBs are controlled by the MCG MAC entity, such as Figure 3As shown, it can be determined first that the non-split DRB with DRB ID=1 is controlled by the MCG MAC CE, and at the same time, it can be determined that the split DRB with DRB ID=3 is controlled by the MCG MAC CE by checking the 0 / 1 indicator configured in the split DRB.

[0108] The terminal determines the corresponding relationship based on the IDs of these DRBs, for example, the corresponding relationship can be determined by the ascending (or descending) order of the DRB IDs. For example, the DRB IDs in the terminal include 1, 3, 5, and 6. DRB ID = 1 is ranked first in the ascending order, then the non-split DRB with DRB ID = 1 corresponds to the first bit in the bitmap, DRB ID = 3 is ranked second in the ascending order, then the split DRB with DRB ID = 3 corresponds to the second bit in the bitmap, and the remaining bits in the bitmap are invalid bits.

[0109] The terminal MAC entity indicates the bit value of the first bit in the bit map to the PDCP entity of the non-split DRB with DRB ID = 1, and the terminal MAC entity indicates the bit value of the second bit in the bit map to the PDCP entity of the split DRB with DRB ID = 3; the corresponding PDCP entity decides to activate / deactivate the corresponding DRB's duplicate data transmission function based on the indicated bit value.

[0110] Example 2

Figure 4 FIG. 1 is a schematic diagram of the structure of a terminal according to an embodiment of the present invention; FIG. Figure 4 As shown, the terminal includes: a first determining unit 31 and a second determining unit 32; wherein,

[0112] The first determining unit 31 is configured to determine a bit position in a received bitmap according to the indication information corresponding to the DRB configuration and / or a preset rule; the bitmap is one of the two received bitmaps;

[0113] The second determining unit 32 is configured to determine activation / deactivation of the duplicate data transmission function of the DRB based on the indication of the bit determined by the first determining unit 31.

Figure 5 As shown, the terminal also includes a receiving unit 33, which is configured to receive the bit maps of the MAC entity corresponding to the MCG and the MAC entity corresponding to the SCG respectively before the first determination unit 31 determines the bit positions in the received bit map according to the indication information corresponding to the DRB configuration and / or preset rules.
