Abstract
The present invention relates to a method for transmitting signals by a transmission end in a wireless communication system. In particular, the method includes the steps of: configuring one Packet Data Convergence Protocol (PDCP) entity, at least one first RLC entity related to the one PDCP entity and at least one second RLC entity related to the one PDCP entity; determining whether a service data unit (SDU) to be transmitted is a special SDU or not; if the SDU is the special SDU, transmitting the SDU to the at least one first RLC entity; and if the SDU is not the special SDU, transmitting the SDU to the at least one second RLC entity.
Claims10
A method for processing signals by a Packet Data Convergence Protocol (PDCP) entity of a transmission end in a wireless communication system, the method comprising:
- receiving a data unit to be transmitted from an upper layer;
- and
- submitting the data unit to at least one of multiple Radio Link Control (RLC) entities associated with the PDCP entity;
- wherein, based on the data unit being related to negative acknowledgement (NACK), submitting the data unit comprises:
- submitting the data unit to all of the multiple RLC entities associated with the PDCP entity by duplicating the data unit.
A user equipment (UE) in a wireless communication system, the UE comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
- receiving a data unit to be transmitted from an upper layer;
- and
- submitting the data unit to at least one of multiple Radio Link Control (RLC) entities associated with the PDCP entity;
- wherein, based on the data unit being related to negative acknowledgement (NACK), submitting the data unit comprises:
- submitting the data unit to all of the multiple RLC entities associated with the PDCP entity by duplicating the data unit.
A method for processing signals by a Packet Data Convergence Protocol (PDCP) entity of a reception end in a wireless communication system, the method comprising:
- receiving at least one data unit from at least one of multiple Radio Link Control (RLC) entities associated with the PDCP entity;
- and
- delivering the at least one data unit to an upper layer,
- wherein, based on the at least one data unit being related to negative acknowledgement (NACK), receiving the at least one data unit comprises:
- receiving the at least one data unit duplicated, from all of the multiple RLC entities associated with the PDCP entity.
A base station (BS) in a wireless communication system, the UE comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
- receiving at least one data unit from at least one of multiple Radio Link Control (RLC) entities associated with the PDCP entity;
- and
- delivering the at least one data unit to an upper layer,
- wherein, based on the at least one data unit being related to negative acknowledgement (NACK), receiving the at least one data unit comprises:
- receiving the at least one data unit duplicated, from all of the multiple RLC entities associated with the PDCP entity.
