    摘要: Methods and apparatus for allocating acknowledgement channels in a communication network. A linking scheme is established between indices of a plurality of physical hybrid automatic repeat-request indicator channels (PHICHs), and a combination of indices of control channel elements (CCEs) or indices of physical resource blocks (PRBs) and indices of demodulation reference signals (DMRSs). A base station (BS) transmits a scheduling grant to a unit of user equipment (UE) by using a plurality of CCEs. In response to receiving a data packet and a DMRS from the UE, the BS determines an index of a PHICH within the plurality of PHICHs in dependence upon at least one index of the CCEs used to transmit the scheduling grant or at least one index of the PRBs used to transmit the data packet, and an index of the transmitted DMRS in accordance with the linking scheme established. Finally, the BS transmits an acknowledgement signal to the UE by using the PHICH indicated by the determined index.

    摘要: Methods and apparatus for transmitting Asynchronous Hybrid Automatic Repeat reQuest (ARQ) process identities in a wireless communication system. A linking scheme is established between at least two sets of process identities of two respective corresponding codewords. When a first process identity is selected from among a first set of process identities of a first codeword, a second process identity may be derived in dependence upon the first process identity and the established linking scheme. Finally, a first packet from the first codeword is transmitted using a first transmission channel indicated by the first process identity, and a second packet is transmitted from the second codeword using a second transmission channel indicated by the second process identity. In addition, a control message including only the first process identity is transmitted.

    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 and a circuit for generating cyclic redundancy checks. The method calculates a plurality of cyclic redundancy checks for a transport block with a plurality of information bits.
    A transport block CRC is calculated for a transport block including a plurality of information bit. A transport block including the transport block CRC is segmented into a plurality of subsets and a plurality of cyclic redundancy checks are calculated for the plurality of subsets. At least one cyclic redundancy check among the plurality of cyclic redundancy checks is calculated based on a subset of information bits. In addition, a transport block cyclic redundancy check may be calculated based on all the information bits.
