1. An information processing method performed by a transmission terminal, comprising:
determining, for a sidelink interface, whether to enable a bearer-splitting transmission mode for a radio bearer;
obtaining a relationship between a Packet Data Convergence Protocol (PDCP) entity corresponding to the radio bearer and Radio Link Control (RLC) entities corresponding to the radio bearer in a case of determining to enable the bearer-splitting transmission mode for the radio bearer;
wherein a quantity of the RLC entities corresponding to the PDCP entity is N, Nis an integer and N≥2,
wherein,
obtaining the relationship between the Packet Data Convergence Protocol (PDCP) entity corresponding to the radio bearer and the Radio Link Control (RLC) entities corresponding to the radio bearer comprises:
obtaining a predetermined relationship among logical channel identities of multiple RLC layers corresponding to the radio bearer, wherein, a mode of predetermination comprises any one of following: predetermination in a protocol; predetermination in pre-configuration information of the transmission terminal and a reception terminal;
or,
obtaining the relationship between the Packet Data Convergence Protocol (PDCP) entity corresponding to the radio bearer and the Radio Link Control (RLC) entities corresponding to the radio bearer comprises:
receiving a configuration signaling from a network-side device;
obtaining, based on the configuration signaling, a relationship among logical channel identities of multiple RLC layers corresponding to the radio bearer;
or,
obtaining the relationship between the packet data convergence protocol (PDCP) entity corresponding to the radio bearer and the radio link control (RLC) entities corresponding to the radio bearer comprises:
determining, by the transmission terminal itself, a relationship among logical channel identities of multiple RLC layers corresponding to the radio bearer.
