    摘要： A method and apparatus of rate matching process of the hybrid Automatic Repeat reQuestion (HARQ) operation in which coded bits are selected for a transmission depends on whether the transmission is a first transmission of a new packet or a retransmission of an existing packet. In downlink of long term evolution (LTE) system, a downlink grant message is transmitted along with the packet data transmission. The grant message may also contain the redundancy version (RV). A new data indicator (NDI) is introduced to indicate the start of a new packet. The improved method of rate matching may be implanted into either a transmitter or a receiver.

    摘要： Methods for operating a user equipment and a base station in a wireless communication system, and apparatus thereof are provided. The method comprises receiving, from a first base station, a measurement configuration, transmitting, to the first base station, a measurement report according to the measurement configuration, receiving, from a first base station, a RRC reconfiguration message triggering a handover to a second base station, wherein the RRC reconfiguration message includes access information required to access the second base station, performing a synchronization to the second base station, transmitting, to the second base station, a RRC reconfiguration complete message to confirm a completion of the handover, monitoring a physical downlink control channel, PDCCH, from the second base station based on a number of symbols used for the PDCCH of the second base station, wherein the RRC reconfiguration message includes the number of symbols used for the PDCCH of the second base station.

    摘要： A method for a user equipment (UE) to transmit a sounding reference signal (SRS) is provided, comprising: identifying a DL control information (DCI) format; identifying information on a set of time resources that include time resources with fixed downlink (DL) direction, time resources with fixed uplink (UL) direction, and time resources with flexible direction; and transmitting the SRS in the time resource with flexible direction in case that the DCI format is detected and indicates UL direction and suspending transmitting the SRS in the time resource with flexible direction in case that the DCI format is not detected.
