Blind scheduling apparatus and method in a mobile communication system

A scheduling method of a user equipment (UE) in a mobile communication system, the scheduling method comprising:nreceiving a radio resource control (RRC) message including information related to an interval of a second type of uplink (UL) grant and a second cell radio network temporary identifier (C-RNTI) to be used for the second type of UL grant;detecting that a UL grant is available;determining a type of the UL grant if there is no data to transmit using the UL grant;determining to transmit a medium access control (MAC) protocol data unit (PDU) using the UL grant if the type of the UL grant is a first type; anddetermining not to transmit the MAC PDU using the UL grant if the type of UL grant is the second type,wherein the first type of UL grant is associated with a first C-RNTI and the second type of UL grant is associated with the second C-RNTI,wherein an interval of the first type of UL grant is not configured and an interval of the second type of UL grant is configured by the RRC message, andwherein the second C-RNTI and the interval of the second type of UL grant are configured by an evolved Node B (eNB) using a single RRC message.

A user equipment (UE) in a mobile communication system, comprising:na receiver configured to receive a radio resource control (RRC) message including information related to an interval of a second type of uplink (UL) grant and a second cell radio network temporary identifier (C-RNTI) to be used for the second type of UL grant; anda controller configured to detect that UL grant is available, determine a type of the UL grant if there is no data to transmit using the UL grant, determine to transmit a medium access control (MAC) protocol data unit using the UL grant if the type of the UL grant is a first type, and determine not to transmit the MAC PDU using the UL grant if the type of the UL grant is the second type,wherein the first type of UL grant is associated with a first C-RNTI, and the second type of UL grant is associated with the second C-RNTI,wherein an interval of the first type of UL grant is not configured, and the interval of the second type of UL grant is configured by the RRC message, andwherein the second C-RNTI and the interval of the second type of UL grant are configured by an evolved Node B (eNB) using a single RRC message.

A scheduling method of an evolved node B (eNB) in a mobile communication system, the scheduling method comprising:ntransmitting a radio resource control (RRC) message including information related to an interval of a second type of uplink (UL) grant and a second cell radio network temporary identifier (C-RNTI) to be used for the second type of UL grant; andallocating a UL grant,wherein a user equipment (UE) determines to transmit a medium access control (MAC) protocol data unit (PDU) using the UL grant if a type of the UL grant is a first type, andwherein the UE determines not to transmit the MAC PDU using the UL grant if the type of the UL grant is the second type,wherein the first type of UL grant is associated with a first C-RNTI, and the second type of UL grant is associated with the second C-RNTI,wherein an interval of the first type of UL grant is not configured, and the interval of the second type of UL grant is configured by the RRC message, andwherein the second C-RNTI and the interval of the second type of UL grant are configured by the eNB using a single RRC message.

An evolved node B (eNB) in a mobile communication system, comprising:na transmitter configured to transmit a radio resource control (RRC) message including information related to an interval of a second type of uplink (UL) grant and a second cell radio network temporary identifier (C-RNTI) to be used for the second type of UL grant; anda controller configured to allocate a UL grant,wherein a user equipment (UE) determines to transmit a medium access control (MAC) protocol data unit (PDU) using the UL grant if a type of the UL grant is a first type, andwherein the UE determines not to transmit the MAC PDU using the UL grant if the type of the UL grant is the second type,wherein the first type of UL grant is associated with a first C-RNTI, and the second type of UL grant is associated with the second C-RNTI,wherein an interval of the first type of UL grant is not configured, and the interval of the second type of UL grant is configured by the RRC message, andwherein the second C-RNTI and the interval of the second type of UL grant are configured by the eNB using a single RRC message.
