Abstract
The present specification relates to a method for transmitting medium access control protocol data unit (MAC PDU) in a wireless communication system. The method, which is performed by a terminal, comprises the steps of: transmitting a control signal through a physical uplink channel to a base station; and transmitting the MAC PDU including terminal identifier information for identifying the terminal to the base station using contention resources within contention-based PUSCH zone (CP zone).
Claims11
A method for transmitting/receiving a medium access control protocol data unit (MAC PDU) in a wireless communication system, the method performed by a user equipment (UE) comprising:
- receiving a contention based PUSCH (CP) zone configuration-related information from a base station (BS);
- transmitting a control signal to the BS through a physical uplink channel;
- and
- determining a contention resource for transmitting the MAC PDU in one or more resource blocks forming the CP zone based on the received CP zone configuration-related information,
- wherein the CP zone is a resource region in which the UE can transmit UL data to the BS without allocating an uplink grant from the BS,
- wherein the CP zone is included in a physical uplink shared channel (PUSCH) resource region,
- wherein the MAC PDU is transmitted to the BS through the determined contention resource,
- wherein the MAC PDU comprises UE recognizer information identifying the UE,
- wherein the MAC PDU comprises an MAC header and an MAC control element (CE),
- wherein the UE recognizer information is included in the MAC CE, and
- wherein the MAC header comprises a logical channel identification (LCID) value indicative of the UE recognizer information.
A user equipment for transmitting/receiving a medium access control protocol data unit (MAC PDU) in a wireless communication system, the user equipment comprising:
- a radio frequency (RF) unit for transmitting/receiving a radio signal;
- and
- a processor, wherein:
- the processor receives a contention based PUSCH (CP) zone configuration-related information from a base station (BS), transmits a control signal to the BS through a physical uplink channel, and determines a contention resource for transmitting the MAC PDU in one or more resource blocks forming the CP zone based on the received CP zone configuration-related information,
- the CP zone is a resource region in which the UE can transmit UL data to the BS without allocating an uplink grant from the BS,
- the CP zone is included in a physical uplink shared channel (PUSCH) resource region,
- the MAC PDU is transmitted to the BS through the determined contention resource,
- the MAC PDU comprises UE recognizer information identifying the UE,
- the MAC PDU comprises an MAC header and an MAC control element (CE),
- the UE recognizer information is included in the MAC CE, and
- the MAC header comprises a logical channel identification (LCID) value indicative of the UE recognizer information.
