Configuration for duplication transmission and duplication transmission method and device

A duplication transmission method, comprising:

• receiving, by a terminal, a duplication transmission configuration performed at a network side through a radio resource control (RRC) signalling, wherein the duplication transmission configuration is performed at the network side for each radio bearer of the terminal;
• and
• performing the duplication transmission according to the configuration;
• wherein the duplication transmission configuration comprises a Radio Bearer Identity (RB ID) and a configuration of a packet data convergence protocol (PDCP) entity corresponding to the radio bearer, and the duplication transmission configuration further comprises for uplink transmission, configuring initial states of two logical channels as whether to be in an activated state immediately after the configuration, and for uplink transmission, a configuration as to whether to allow to activate or deactivate the duplication transmission;
• receiving, by the terminal, a media access control (MAC) layer signalling for activating or deactivating the duplication transmission from the network side,
• wherein one logical channel identifier (LCID) value is used to indicate an MAC control element (CE) for activating or deactivating the duplication transmission, and different values of a CE Type field are used to indicate an MAC CE for activating the duplication transmission or an MAC CE for deactivating the duplication transmission;
• or
• an LCID field in an independent MAC subheader is used to indicate that an MAC CE is used to activate or deactivate the duplication transmission, wherein two LCID values are used to indicate an MAC CE for activating the duplication transmission and an MAC CE for deactivating the duplication transmission respectively.

A duplication transmission device, comprising:

• a processor configured to read a program in a memory to perform a process of:
• processing data according to a transceiver requirement;
• a transceiver configured to receive and transmit data under control of the processor to perform processes of:
• receiving a duplication transmission configuration performed at a network side through a radio resource control (RRC) signalling, wherein the duplication transmission configuration is performed at the network side for each radio bearer of a terminal;
• performing the duplication transmission according to the configuration;
• the duplication transmission configuration comprises a Radio Bearer Identity (RB ID) and a configuration of a packet data convergence protocol (PDCP) entity corresponding to the radio bearer, and the duplication transmission configuration further comprises for uplink transmission, configuring initial states of two logical channels as whether to be in an activated state immediately after the configuration, and for uplink transmission, a configuration as to whether to allow to activate or deactivate the duplication transmission;
• receiving a media access control (MAC) layer signalling for activating or deactivating the duplication transmission from the network side,
• wherein one logical channel identifier (LCID) value is used to indicate an MAC control element (CE) for activating or deactivating the duplication transmission, and different values of a CE Type field are used to indicate an MAC CE for activating the duplication transmission or an MAC CE for deactivating the duplication transmission;
• or
• an LCID field in an independent MAC subheader is used to indicate that an MAC CE is used to activate or deactivate the duplication transmission, wherein two LCID values are used to indicate an MAC CE for activating the duplication transmission and an MAC CE for deactivating the duplication transmission respectively.
