The method includes: determining, by a terminal according to first indication information, whether to release a mapping relationship between a first logical channel and a first physical carrier set, after receiving a first message used for indicating deactivation of a duplicate data transmission function. ## Claims ### Claim 1 A method for information indication, the method comprising: determining, by a mobile terminal according to a first indication information carried in a Media Access Control Control Element (MAC CE) or in a Radio Resource Control (RRC) signaling, whether to release a mapping relationship between a first logical channel and a first physical carrier set, after receiving a first message, from a base station, used for indicating deactivation of a duplicate data transmission function, wherein after the mapping relationship between the first logical channel and the first physical carrier set is released, data of the first logical channel is capable of being transmitted on all authorized carriers configured for the mobile terminal. ### Claim 2 (depends on 1) The method of claim 1, wherein the first indication information is carried in an MAC CE or in an MAC CE used for indicating the deactivation of the duplicate data transmission function; or, the first indication information is carried in an RRC signaling used for indicating the deactivation of the duplicate data transmission function. ### Claim 3 (depends on 1) The method of claim 1, wherein the first indication information comprises a first parameter configured in the first logical channel, wherein a radio bearer corresponding to the first logical channel is configured with the duplicate data transmission function. ### Claim 4 (depends on 3) The method of claim 3, wherein the terminal deactivates the duplicate data transmission function of the radio bearer corresponding to the first logical channel after receiving the first message used for indicating the deactivation of the duplicate data transmission function, and determines, according to the first parameter, whether to release the mapping relationship between the first logical channel and the first physical carrier set. ### Claim 5 (depends on 4) The method of claim 4, wherein determining, according to the first parameter, whether to release the mapping relationship between the first logical channel and the first physical carrier set comprises: responsive to a value of the first parameter being a first value, releasing the mapping relationship between the first logical channel and the first physical carrier set; responsive to the value of the first parameter being a second value, not releasing the mapping relationship between the first logical channel and the first physical carrier set. ### Claim 6 (depends on 1) The method of claim 1, wherein the first indication information comprises configuration information of a second physical carrier set, wherein the configuration information of the second physical carrier set is configured in the first logical channel, and a radio bearer corresponding to the first logical channel is configured with the duplicate data transmission function. ### Claim 7 (depends on 6) The method of claim 6, wherein after receiving the first message used for indicating the deactivation of the duplicate data transmission function, the terminal deactivates the duplicate data transmission function of the radio bearer corresponding to the first logical channel, releases the mapping relationship between the first logical channel and the first physical carrier set, and maps the first logical channel to the second physical carrier set. ### Claim 8 (depends on 7) The method of claim 7, wherein after the first logical channel is mapped to the second physical carrier set, data of the first logical channel is capable of being transmitted on the second physical carrier set. ### Claim 9 An apparatus for information indication, comprising: a memory storing processor-executable instructions; and a processor configured to execute the stored processor-executable instructions to perform an operation of: determining, by a mobile terminal according to a first indication information carried in a Media Access Control Control Element (MAC CE) or in a Radio Resource Control (RRC) signaling, whether to release a mapping relationship between a first logical channel and a first physical carrier set, after receiving a first message, from a base station, used for indicating deactivation of a duplicate data transmission function, wherein after the mapping relationship between the first logical channel and the first physical carrier set is released, data of the first logical channel is capable of being transmitted on all authorized carriers configured for the mobile terminal. ### Claim 10 (depends on 9) The apparatus of claim 9, wherein the first indication information is carried in an MAC CE or in an MAC CE used for indicating the deactivation of the duplicate data transmission function; or, the first indication information is carried in an RRC signaling used for indicating the deactivation of the duplicate data transmission function. ### Claim 11 (depends on 9) The apparatus of claim 9, wherein the first indication information comprises a first parameter configured in the first logical channel, wherein a radio bearer corresponding to the first logical channel is configured with the duplicate data transmission function. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the processor is configured to execute the stored processor-executable instructions to further perform an operation of: deactivating the duplicate data transmission function of the radio bearer corresponding to the first logical channel after the first message used for indicating the deactivation of the duplicate data transmission function is received; and determining, according to the first parameter, whether to release the mapping relationship between the first logical channel and the first physical carrier set. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein determining, according to the first parameter, whether to release the mapping relationship between the first logical channel and the first physical carrier set comprises: determining to release the mapping relationship between the first logical channel and the first physical carrier set, responsive to a value of the first parameter being a first value; and determining not to release the mapping relationship between the first logical channel and the first physical carrier set, responsive to the value of the first parameter being a second value. ### Claim 14 (depends on 9) The apparatus of claim 9, wherein the first indication information comprises configuration information of a second physical carrier set, wherein the configuration information of the second physical carrier set is configured in the first logical channel, and a radio bearer corresponding to the first logical channel is configured with the duplicate data transmission function. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the processor is configured to execute the stored processor-executable instructions to further perform operations of: after receiving the first message used for indicating the deactivation of the duplicate data transmission function, deactivating the duplicate data transmission function of the radio bearer corresponding to the first logical channel; releasing the mapping relationship between the first logical channel and the first physical carrier set; and mapping the first logical channel to the second physical carrier set. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein after the first logical channel is mapped to the second physical carrier set, data of the first logical channel is capable of being transmitted on the second physical carrier set.
