3. A base station, comprising:
a processor; and
a memory storing instructions,
wherein the instructions, when run by the processor, cause the base station to perform following steps:
transmitting configuration information of a first RRC parameter and a second RRC parameter, wherein,
the first RRC parameter is pdsch-HARQ-ACK-Codebook parameter whose value is an element in a set {semiStatic, dynamic}; and
the second RRC parameter is pdsch-HARQ-ACK-Codebook-r16 parameter whose value is an element in a set {enhancedDynamic}; wherein
the configuration information causes a user equipment to determine each of a first HARQ-ACK codebook type for HARQ-ACK information for downlink and a second HARQ-ACK codebook type for HARQ-ACK information for sidelink, based on either the first RRC parameter or the second RRC parameter, wherein,
for the first HARQ-ACK codebook type, the first RRC parameter is ignored; and
for the second HARQ-ACK codebook type, the second RRC parameter is ignored and the first RRC parameter is applied.
