Abstract
Provided is a method for a user equipment to duplicately receive an identical control messages. The method includes duplicately receiving identical control messages from a base station and processing the duplicately received identical control messages by mapping same to mutually different logical channels, by using identification information or an identification entity for identifying and processing the duplicately received identical control message.
Claims20
A method for transmitting a data unit by a transmitting device, the method comprising:
- configuring a packet data convergence protocol (PDCP) entity associated with a signaling radio bearer (SRB) or a data radio bearer (DRB);
- configuring a first radio link control (RLC) entity associated with the SRB or DRB and a second RLC entity associated with the SRB or DRB, the second RLC entity being different from the first RLC entity;
- configuring a single medium access control (MAC) entity associated with the first RLC entity and the second RLC entity for the SRB or DRB;
- transmitting, by the transmitting device, the data unit through the PDCP entity, the first RLC entity, and the single MAC entity, the first RLC entity being identified as a primary RLC entity, the data unit being transmitted by the transmitting device associating a first logical channel with the single MAC entity, the first logical channel being mapped to the first RLC entity;
- and
- transmitting, by the transmitting device, a duplicate of the data unit through the PDCP entity, the second RLC entity, and the single MAC entity, the duplicate of the data unit being transmitted by the transmitting device associating a second logical channel with the single MAC entity, the second logical channel being mapped to the second RLC entity,
- wherein the first logical channel is identified by a first logical channel identity (LCID), and the second logical channel is identified by a second LCID,
- wherein the first LCID and the second LCID are values configured by a radio resource control (RRC) message,
- wherein at least one of the first LCID and the second LCID is used as a logical channel identity for an associated SRB among a plurality of SRBs to distinguish the associated SRB from other SRBs, and
- wherein the same LCID value as the at least one of the first LCID and the second LCID is used as a logical channel identity for an associated DRB among a plurality of DRBs to distinguish the associated DRB from other DRBs.
