摘要： A method and apparatus for performing contention resolution for contention based physical uplink shared channel (CB-PUSCH) transmission in a wireless communication system is provided. A user equipment (UE) performs a first hybrid automatic repeat request (HARQ) transmission on a CB-PUSCH to a network, and determines whether contention on the CB-PUSCH is resolved. The CB-PUSCH is a channel for UL data allocated by a pre-configured UL grant which is shared by multiple UEs. If a UL grant includes an identity of the UE, it is determined that contention on the CB-PUSCH is resolved. The UE may perform a second HARQ transmission for the first HARQ transmission on a PUSCH to the network by using the UL grant.

摘要： The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting a HARQ (Hybird-ARQ) feedback signal in the wireless communication system, wherein the method comprises: receiving 1st to ith data within a time window comprising subframes 1 to N, wherein the 1st to Nth data are transmitted by a base station for the time window, wherein the ‘i’ is a natural number no more than the ‘N’, and the 1st to the Nth data are the same, sequentially decoding the 1st to the ith data, wherein the ith data received at a subframe i is data first successfully decoded, and transmitting an ACK (Acknowledgement) signal for all the 1st to the Nth data at a subframe i+X, wherein the ‘X’ is a predetermined number for transmission of the HARQ signal.

摘要： The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing autonomous RLC retransmission in a wireless communication system, the method comprising: transmitting a RLC PDU to a RLC receiver on a first transmission opportunity; checking, by the RLC transmitter, whether a condition for performing a RLC PDU retransmission procedure is met or not, when the RLC PDU is transmitted to the RLC receiver on the first transmission opportunity; and re-transmitting, by the RLC transmitter, the RLC PDU during consecutive transmission opportunities following the first transmission opportunity if a condition is met.

摘要： A method and apparatus for controlling uplink transmissions on Discontinuous reception (DRX) operation are provided. A wireless device chooses that a Channel Quality Indicator (CQI)/Precoding Matrix Index (PMI)/Rank Indicator (RI)/Precoding Type Indicator (PTI) on a Physical Uplink Control Channel (PUCCH) are not reported at a subframe n if an onDurationTimer is determined to be not active at the sub-frame n. An uncertainty about the uplink control information during the On Duration occurred by previous DRX operation can be resolved.
