Method for reporting user equipment capability information and apparatus

User equipment (UE), comprising:

• a receiver configured to obtain UE capability information of the UE;
• a processor configured to:
• determine whether a size of the UE capability information exceeds a maximum tolerance that can be processed by a Packet Data Convergence Protocol (PDCP) layer of the UE, and
• when the size of the UE capability information exceeds the maximum tolerance that can be processed by the PDCP layer of the UE, split the UE capability information into at least two pieces of UE capability information, wherein each piece of the at least two pieces of UE capability information does not exceed the maximum tolerance that can be processed by the PDCP layer;
• and
• a transmitter configured to report at least one piece of the at least two pieces of UE capability information to a network side device.

A base station, wherein the base station is applied to a network side device, the base station comprising:

• a transmitter configured to send, to a user equipment (UE), a first request message that UE capability information needs to be reported;
• a receiver configured to receive a first radio resource control (RRC) message fed back by the UE based on the first request message, wherein the first RRC message carries at least one piece of at least two pieces of UE capability information formed after the UE capability information is split;
• the processor is configured to:
• determine, based on the received at least one piece of UE capability information, whether the UE has at least another piece of UE capability information or whether the UE is further required to report at least another piece of UE capability information, and
• when the UE has the at least another piece of UE capability information or the UE is further required to report at least another piece of UE capability information, generate a second request message;
• and
• the transmitter is further configured to send the second request message to the UE.
