Based on the above-described wireless communication system shown in FIG. 1 and the protocol architecture shown in FIG. 2 being an atypical example, the following embodiments are proposed.

Embodiment 1

Referring to FIG. 3, a method for controlling a secondary cell according to an embodiment of the present invention is shown. The method may be exemplarily applied to a terminal in the wireless communication system shown in FIG. 1. The method includes:

S301: Receive a first MAC CE indicating that the first target radio bearer data replication transmission function is activated;

S302: When the first target logical channel (LCH, Logical CHannel) in the first target radio bearer has a unique mapping relationship with the secondary cell, obtain the foregoing according to a one-to-one correspondence between the pre-configured logical channel and the secondary cell. a first target secondary cell corresponding to the first target logical channel;

S303: Activate a data replication transmission function of the first target radio bearer and the first target secondary cell.

It can be seen from the technical solution shown in FIG. 3 that, in this embodiment, the terminal can achieve the auxiliary function after receiving the MAC CE only once by the one-to-one correspondence between the pre-configured logical channel and the secondary cell. Activation of the cell and activation of the duplication transmission function of the radio bearer. Compared with the current related technologies, the transmission of MAC CE between the base station and the base station is saved, and the signaling overhead between the base station and the terminal is reduced.

For the technical solution shown in FIG. 3, in a possible implementation manner, the format of the MAC CE is a 1-byte byte bitmap; wherein the bitmap has a correspondence with a radio bearer identifier, and therefore, The bitmap in the MAC CE determines one or more target radio bearers. For example, each byte in the bitmap has a corresponding relationship with the radio bearer identifier. Therefore, in this implementation manner, the bitmap can be used to indicate eight radio bearer identifiers, and the radio bearer #1 is sequentially selected from the highest bit to the lowest bit of the bitmap. , radio bearer #2, radio bearer #3, radio bearer #4, radio bearer #5, radio bearer #6, radio bearer #7, and radio bearer #8. And when the setting byte is "1", indicating that the radio bearer corresponding to the byte bit is the first target radio bearer; when the setting byte is "0", indicating that the radio bearer corresponding to the byte bit is not the first Target radio bearer. Therefore, when the bitmap in the MAC CE is "11000000", it indicates that the radio bearer #1 and the radio bearer #2 are the first target radio bearers, and the radio bearers #3 to #8 to the radio bearer #8 are non-first targets. Wireless bearer.

Specifically, each secondary cell is configured with a deactivation timer sCellDeactivationTimer, and the timing period of the timer is an activation state duration of the first target secondary cell, and when the secondary cell is activated, the timer starts timing; When the timer expires, it indicates that the timer expires, and the secondary cell corresponding to the timer is deactivated.

In addition, in the technical solution shown in FIG. 3, the first target radio bearer specifically includes a data radio bearer based on a carrier aggregation CA architecture. Based on this, in the first target radio bearer, at least one first target RLC entity is included; and the first target RLC entities each have a one-to-one corresponding first target logical channel.

It should be noted that, for a single RLC entity, one or more physical carriers may be controlled, and a single RLC entity only corresponds to one logical channel. Therefore, when a single logical channel is only used to transmit data of a single carrier or cell, then The RLC entity, the logical channel, and the secondary cell have a one-to-one mapping relationship. Referring to FIG. 4, the RLC entity A corresponds to the logical channel A, and the logical channel A corresponds to the secondary cell A one by one. Based on the mapping relationship, the secondary cell that needs to be activated can be obtained, so that the terminal can activate the first target secondary cell only by receiving the MAC CE once, and enable the replication data transmission function of the first target radio bearer, thereby saving the terminal and the Signaling overhead between base stations.

In addition, if the activated target secondary cell needs to be deactivated and the radio bearer with the duplicate data duplication transmission function enabled is turned off, the foregoing solution may further include:

Receiving a second MAC CE for instructing deactivation of the second target secondary cell;

Obtaining a second target logical channel that is in one-to-one correspondence with the second target secondary cell;

Deactivating the second target secondary cell and deactivating a duplicate data duplication transmission function of the 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 a timeout, so that the second target secondary cell The activation state is deactivated and deactivated, and the duplicate data duplication transmission function of the second target radio bearer is turned off. Therefore, the terminal can still deactivate the secondary cell only after receiving the MAC CE once, and deactivate the duplicate data duplication transmission function of the radio bearer.

The embodiment of the present invention provides a method for controlling a secondary cell, where the terminal acquires a target secondary cell corresponding to the target radio bearer from the received MAC CE, and controls an activation state of the duplicate data duplication transmission function of the target secondary cell, Therefore, it is not necessary to perform control by receiving the MAC CE twice, which saves signaling overhead between the terminal and the base station.

Wireless bearer data copy transmission function. Compared with the current related technologies, the transmission of MAC CE between the base station and the base station is saved, and the signaling overhead between the base station and the terminal is reduced.

Obtaining a target radio bearer to which the target RLC entity belongs.

It should be noted that the data radio bearer may include multiple RCL entities. As shown in FIG. 4 in the foregoing embodiment, a single RLC entity only corresponds to one logical channel. Therefore, when a single logical channel is used only for transmitting a single carrier or a secondary cell. When there is data, then there is a one-to-one mapping relationship between the RLC entity, the logical channel, and the secondary cell.

For the technical solution shown in FIG. 5, sending a MAC CE for indicating the target radio bearer may include:

Generating a bitmap bitmap corresponding to the target radio bearer identifier; wherein the bitmap is 1 byte byte;

The structure of the MAC CE is set according to the bitmap.

Specifically, each byte in the bitmap has a corresponding relationship with the radio bearer identifier. When the byte is set to "1", the radio bearer corresponding to the byte bit is indicated as the target radio bearer; the set byte is "0". When the radio bearer corresponding to the byte bit is indicated as a non-target radio bearer.

Transmitting, by the second MAC CE, a second media access control layer control unit MAC CE for invoking the target secondary cell, where the second MAC CE is used to deactivate the data replication transmission function of the target radio bearer and the deactivation station The target secondary cell.

Therefore, the terminal can still deactivate the secondary cell only after receiving the MAC CE once, and deactivate the duplicate data duplication transmission function of the radio bearer. Thereby, the signaling overhead between the base station and the terminal is saved.
