    摘要: A wireless communication device includes a receiver configured to receive a transport block with a sequence of bits wherein A is the number of bits, a first cyclic redundancy check (CRC) coder configured to generate a first block of CRC parity bits on a transport block and to associates the first block of CRC parity bits with the transport block, wherein a number of CRC parity bits in the first block is L, a segmenting entity configured to segment the transport block into multiple code blocks after associating when A+L is larger than 6144, a second CRC coder configured to generate a second block of CRC parity bits on each code block and to associate a second block of CRC parity bits with each code block, and a channel encoder configured to encode each of the code blocks including the associated second block of CRC parity bits if A+L>6144.

    摘要: A method in a transmitter for data collision avoidance in an uncoordinated frequency hopping communication system is disclosed. The base station (104) first determines (304) that a first data set to be sent to a first device (105) and a second data set to be sent to a second device (107) are scheduled to be transmitted simultaneously on a first frequency of a frequency hop-set. The device then transmits (310) the first data set on the first frequency of the frequency hop-set. The base station delays (312) transmission of the second data set, and finally transmits (316) the second data set on a second frequency of a frequency hop-set.
