Abstract
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting or receiving a MAC PDU in a wireless communication system, the method comprising: setting a LCID field in a MAC subheader to a first value indicating that an eLCID field is included in the MAC subheader when a MAC PDU including the LCID field and the eLCID field is to be generated, setting the eLCID field to a second value identifying a logical channel of a MAC SDU or a type of a MAC CE, and generating and transmitting the MAC PDU including the LCID field and the eLCID field, and the MAC SDU or the MAC CE.

A method for a device operating in a wireless communication system, the method comprising:
- generating a Medium Access Control (MAC) protocol data unit (PDU) including a MAC PDU subheader, the MAC PDU subheader including a first octet of 8 bits;
- and
- transmitting the generated MAC PDU to a second device,
- wherein the first octet includes a logical channel identity (LCID) field, and a specific value of the LCID field informs of that a second octet of 8 bits following the first octet is presented for an extended LCID (eLCID) field in the MAC PDU subheader,
- wherein a length (L) field related to a length of a MAC control element (CE) is included in a third octet of 8 bits in the MAC PDU subheader, and the second octet is followed by the third octet,
- wherein the first octet includes the LCID field and a reserved bit, and the second octet includes only the eLCID field, and the third octet includes only the L field,
- wherein there is no octet between the first octet and the second octet, and
- wherein the eLCID field identifies a type of the MAC CE.
A device operating in a wireless communication system, the device comprising:
- a transceiver;
- and
- a processor operatively connected to the transceiver, the processor configured for:
- generating a Medium Access Control (MAC) protocol data unit (PDU) including a MAC PDU subheader, the MAC PDU subheader including a first octet of 8 bits;
- and
- transmitting the generated MAC PDU to a second device,
- wherein the first octet includes a logical channel identity (LCID) field, and a specific value of the LCID field informs of that a second octet of 8 bits following the first octet is presented for an extended LCID (eLCID) field in the MAC PDU subheader,
- wherein a length (L) field related to a length of a MAC control element (CE) is included in a third octet of 8 bits in the MAC PDU subheader, and the second octet is followed by the third octet,
- wherein the first octet includes the LCID field and a reserved bit, and the second octet includes only the eLCID field, and the third octet includes only the L field,
- wherein there is no octet between the first octet and the second octet, and
- wherein the eLCID field identifies a type of the MAC CE.
A method for a device operating in a wireless communication system, the method comprising:
- receiving, from a second device, a Medium Access Control (MAC) protocol data unit (PDU) including a MAC PDU subheader, the MAC PDU subheader including a first octet of 8 bits,
- decoding the MAC PDU,
- wherein the first octet includes a logical channel identity (LCID) field, and a specific value of the LCID field informs of that a second octet of 8 bits following the first octet is presented for an extended LCID (eLCID) field in the MAC PDU subheader,
- wherein a length (L) field related to a length of a MAC control element (CE) is included in a third octet of 8 bits in the MAC PDU subheader, and the second octet is followed by the third octet,
- wherein the first octet includes the LCID field and a reserved bit, and the second octet includes only the eLCID field, and the third octet includes only the L field,
- wherein there is no octet between the first octet and the second octet, and
- wherein the eLCID field identifies a type of the MAC CE.
