    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： A method includes separating resource elements from multiple code blocks into different groups, and decoding the code bits of the resource elements within each group without waiting for a completed reception of a transport block to start decoding.
    A method includes separating coded bits from multiple code blocks into different groups, and decoding the code blocks containing coded bits within each group. A first CRC is attached to the transport block and a second CRC is attached to at least one code block from the transport block.
    An improved channel interleaver design method including mapping from coded bits of different code blocks to modulation symbols, and mapping from modulation symbols to time, frequency, and spatial resources, to make sure each code block to get roughly the same level of protection.

    摘要： Methods and apparatus for transmitting power setting information in a downlink Physical Downlink Shared Channel (PDSCH) in a communication system. In this communication system, a plurality of methods for calculating traffic-to-pilot ratios (T2P) are established. In addition, a mapping scheme between a plurality of overhead signals and a plurality of reference signal (RS) overhead ratios, η RS , and the plurality of T2P calculation methods is established. A user-specific T2P ratio P B , k / P RS for certain OFDM symbols, a RS overhead ratio η RS and a calculation method selected from the plurality of T2P calculation methods are assigned to a wireless terminal. Then, an overhead signal corresponding to both of the assigned RS overhead ratio η RS and the assigned T2P calculation method is selected in accordance with the mapping scheme and is transmitted to the wireless terminal. In addition, the user-specific traffic-to-pilot ratio P B , k / P RS is transmitted to the wireless terminal. The wireless terminal may calculate the traffic-to-pilot ratios across different transmission antennas and different OFDM symbols in dependence upon the received traffic-to-pilot ratio P B,k / P RS , and the RS overhead ratio and the T2P calculation method indicated by the RS overhead signal.
