1. A bearer establishment method, performed by a terminal, the method comprising:
receiving first information, wherein the first information carries a part of configuration parameters of a Layer 2 (L2) configuration parameter; and
establishing, according to a first L2 configuration parameter of a first Multicast Broadcast Service (MBS), a bearer corresponding to the first MBS, wherein the first L2 configuration parameter is determined based on the part of configuration parameters of the L2 configuration parameter carried in the first information and a default L2 configuration parameter,
wherein the first L2 configuration parameter is used to indicate at least one of the following:
a parameter of a Packet Data Convergence Protocol (PDCP) entity on the bearer, wherein the parameter of the PDCP entity comprises at least one of the following: a header compression configuration, a security configuration, a reordering timer configuration, or a PDCP Sequence Number (SN) size; or
a parameter of a Radio Link Control (RLC) entity of the bearer, wherein the parameter of the RLC entity comprises at least one of the following: an RLC transmission mode, an RLC SN length, a reassembly timer length, or a related parameter of an AM status feedback.
