Abstract
According to the present invention, a user equipment (UE) receives semi-persistent scheduling (SPS) resource configuration information relating to SPS resources and receives an SPS command indicating activation or deactivation of the SPS resources. The UE flushes, in response to the SPS command, a buffer of an HARQ process associated with an SPS resource to transmit an SPS confirmation medium access control (MAC) control element (CE). The UE transmits a new MAC protocol data unit (PDU) including the SPS confirmation MAC CE on the SPS resource by using the HARQ process.
Claims8
A method of transmitting an uplink signal by a user equipment (UE), the method comprising:
- receiving semi-persistent scheduling (SPS) resource configuration information on SPS resources;
- receiving an SPS command indicating activation or release of the SPS resources;
- flushing a buffer of a hybrid automatic repeat and request (HARQ) process related to an SPS resource on which an SPS confirmation medium access control (MAC) control element (CE) is to be transmitted as a response to the SPS command;
- and
- transmitting a new MAC protocol data unit (PDU) including the SPS confirmation MAC CE on the SPS resource using the HARQ process.
A user equipment (UE) for transmitting an uplink signal, the UE comprising,
- a radio frequency (RF) unit, and
- a processor configured to control the RF unit,
- wherein the processor is configured to:
- control the RF unit to receive semi-persistent scheduling (SPS) resource configuration information on SPS resources;
- control the RF unit to receive an SPS command indicating activation or release of the SPS resources;
- flush a buffer of a hybrid automatic repeat and request (HARQ) process related to an SPS resource on which an SPS confirmation medium access control (MAC) control element (CE) is to be transmitted as a response to the SPS command;
- and
- control the RF unit to transmit a new MAC protocol data unit (PDU) including the SPS confirmation MAC CE on the SPS resource using the HARQ process.
