The present invention can be applied to each of a plurality of serving cells set for the terminal devices 1A to 1C.

Referring to fig. 2, which shows a protocol layer architecture of duplicate Data duplicate transmission under CA technology, in fig. 2, a PDCP layer duplicates configured Data according to a PCDP Service Data Unit (SDU), so as to obtain an original PDCP PDU and a duplicate PDCP PDU (Duplicated PDCP PDU), and then the PDCP PDU passes through an R L C Entity (R L C Entity) a, and the Duplicated PDCP PDU enters a MAC layer through an R L C Entity a, and then the PDCP PDU and the Duplicated PDCP PDU are respectively set on different physical carriers for transmission through the MAC layer.
The following embodiments are proposed based on the above-described wireless communication system shown in fig. 1 and the protocol architecture shown in fig. 2 as atypical examples.
Example one
Referring to fig. 3, which illustrates a control method of a secondary cell provided in an embodiment of the present invention, and the method may be exemplarily applied to a terminal in the wireless communication system shown in fig. 1, and the method includes:
s301: receiving a first MAC CE indicating activation of a first target radio bearer data duplication transmission function;
s302, when a first target logical CHannel (L CH, &lttTtranslation = L "&tttL &lttt/T &tttlogical CHannel) in the first target radio bearer has a unique mapping relation with an auxiliary cell, acquiring a first target auxiliary cell corresponding to the first target logical CHannel according to a one-to-one correspondence relation between pre-configured logical channels and auxiliary cells;
s303: and activating the data replication transmission function of the first target radio bearer and the first target secondary cell.
As can be seen from the technical solution shown in fig. 3, in this embodiment, the terminal can activate the secondary cell and activate the duplicated data duplicate transmission function of the radio bearer after receiving the MAC CE only once through the one-to-one correspondence between the preconfigured logical channel and the secondary cell. Compared with the prior art, the method saves one-time transmission of the MAC CE between the base station and the terminal, and reduces the signaling overhead between the base station and the terminal.
For the technical solution shown in fig. 3, in a possible implementation manner, the format of the MAC CE is a 1-byte bitmap; the bitmap and the radio bearer identifier have a corresponding relationship, so that one or more target radio bearers can be determined through the bitmap in the MAC CE. For example, each byte in the bitmap has a corresponding relationship with the rb identifier, and thus, in this implementation, the bitmap can be used to indicate eight rb identifiers, which sequentially correspond to rb #1, rb #2, rb #3, rb #4, rb #5, rb #6, rb #7, and rb #8 from the highest bit to the lowest bit of the bitmap. And when the byte is set to be 1, indicating the radio bearer corresponding to the byte bit as a first target radio bearer; when the byte is set to "0", the rb corresponding to the byte bit is indicated as a non-first target rb, so that when the bitmap in the MAC CE is "11000000", it indicates that rb #1 and rb #2 are first target rbs, and rbs #3 to rb #8 are non-first target rbs.
For the technical solution shown in fig. 3, the activating the first target secondary cell in step S304 may be implemented according to the current activation state of the first target secondary cell, and may include:
activating the first target secondary cell when the first target secondary cell is in a deactivated state;
starting or restarting a deactivation timer (sCellDeactivationTimer) of the first target secondary cell when the first target secondary cell is in an activated state.
Specifically, each secondary cell is correspondingly provided with a deactivation timer sCellDeactivationTimer, the timing period of the timer is the activation state duration of the first target secondary cell, and the timer starts to time after the secondary cell is activated; and when the timer is overtime, the timing period is invalid, and the secondary cell corresponding to the timer is deactivated.
Based on this, in the first target radio bearer, at least one first target R L C entity is included, and the first target R L C entities each have a one-to-one corresponding first target logical channel.
It should be noted that, for a single R L C entity, one or more physical carriers may be controlled, and a single R L C entity corresponds to only one logical channel, so when a single logical channel is only used for transmitting data of a single carrier or cell, then, there is a one-to-one mapping relationship among the R L C entity, the logical channel, and the secondary cell, referring to fig. 4, the R L C entity a corresponds to the logical channel a one to one, and the logical channel a corresponds to the secondary cell a one to one.
In addition, if it is required to deactivate the activated target secondary cell and close the radio bearer with the duplicate data duplicate transmission function turned on, on the basis of the above scheme, the method may further include:
receiving a second MAC CE for indicating deactivation of a second target secondary cell;
acquiring second target logical channels corresponding to the second target secondary cells one by one;
and deactivating the second target secondary cell and deactivating a duplicate data duplicate transmission function of a second radio bearer corresponding to the second target logical channel.
Specifically, deactivating the second target secondary cell may include setting a deactivation timer sCellDeactivationTimer of the second target secondary cell to timeout, so that the activation state of the second target secondary cell is deactivated and deactivated, and closing a duplicate data duplicate transmission function of the second target radio bearer. Therefore, the terminal still only needs to receive the MAC CE once to deactivate the secondary cell and deactivate the duplicate data duplicate transmission function of the radio bearer.
The embodiment of the invention provides a control method of an auxiliary cell, wherein a terminal acquires a target auxiliary cell corresponding to a target radio bearer from a received MAC CE and controls the activation state of the duplicate data duplicate transmission function of the target auxiliary cell, so that the control is not required to be carried out by receiving the MAC CE twice, and the signaling overhead between the terminal and a base station is saved.
Example two
Based on the same inventive concept of the foregoing embodiments, referring to fig. 5, a method for controlling a secondary cell according to an embodiment of the present invention is shown, and the method may be exemplarily applied to a base station in the wireless communication system shown in fig. 1, where the method includes:
s501: acquiring a target logical channel corresponding to a target secondary cell;
s502: acquiring a corresponding target radio bearer according to the target logical channel;
s503: sending a media access control layer control element (MAC CE) for indicating to activate a data copy transmission function of the target radio bearer;
wherein the MAC CE is configured to activate a data duplication transmission function of the target radio bearer and the target secondary cell.
Through the technical scheme shown in fig. 5, after the terminal receives the MAC CE indicating the target radio bearer, it is able to learn the target secondary cell according to the technical scheme shown in the foregoing embodiment, and activate the target secondary cell and activate the data duplication transmission function of the target radio bearer. Compared with the prior art, the method saves one-time transmission of the MAC CE between the base station and the terminal, and reduces the signaling overhead between the base station and the terminal.
For the technical solution shown in fig. 5, acquiring the target logical channel corresponding to the target secondary cell may include: acquiring the target logical channel corresponding to the target secondary cell according to the one-to-one correspondence between the preconfigured logical channel and the secondary cell;
based on this, the obtaining the corresponding target radio bearer according to the target logical channel may include:
acquiring a target R L C entity corresponding to the target logical channel;
and acquiring the target radio bearer to which the target R L C entity belongs.
It should be noted that, the data radio bearer may include multiple RC L entities, and as shown in fig. 4 in the foregoing embodiment, a single R L C entity corresponds to only one logical channel, so when a single logical channel is only used for transmitting data of a single carrier or a secondary cell, then there is a one-to-one mapping relationship between the R L C entity, the logical channel, and the secondary cell.
For the technical solution shown in fig. 5, the sending the MAC CE for indicating the target radio bearer may include:
generating a bitmap corresponding to the target radio bearer identifier; wherein the bitmap is 1 byte;
and setting the structure of the MAC CE according to the bitmap.
Specifically, each byte in the bitmap has a corresponding relationship with the radio bearer identifier, and when the byte can be set to be "1", the radio bearer corresponding to the byte bit is indicated as a target radio bearer; when the byte is set to "0", it indicates that the rb corresponding to the byte bit is a non-target rb.
In addition, if it is required to deactivate the activated target secondary cell and close the radio bearer with the duplicate data duplicate transmission function turned on, on the basis of the above scheme, the method may further include:
sending a second media access control layer control element (MAC CE) for indicating to deactivate the target secondary cell; wherein the second MAC CE is configured to deactivate a data duplication transmission function of the target radio bearer and deactivate the target secondary cell.
Therefore, the terminal still only needs to receive the MAC CE once to deactivate the secondary cell and deactivate the duplicate data duplicate transmission function of the radio bearer. Thereby saving signaling overhead between the base station and the terminal.
