Embodiment 1
[0172] Example exemplary flowchart of a wireless transmission of the embodiment 1, as attached figure 1 Indicated. Attach figure 1 In the middle, the base station N1 is a serving cell of the UE U2 to maintain the base station. Attach figure 1 In block F1, F2 of a block, the step of block block F3 and F4, respectively, is optional.
[0173] For N1, a first transmission information in step S11; the number of bits of the third bit sub-block is determined in step S12; channel coding is performed in step S13; transmitting a first radio signal in a step S14.
[0174] For U2, received at step S21, the first information; receiving a first wireless signal in step S22; assumed to be performed based on a first channel in step S23 predecoder; determining a third bit sub-block in step S24 the bit number; channel decoding performed in step S25.
[0175] In Example 1, the first bit of an input block is N1 channel coding. The channel-coded code based on polarization. The channel encoded output N1...
Embodiment 2
[0188] Bit block schematic configuration of a first exemplary embodiment 2 of the embodiment, as attached figure 2 Indicated.
[0189] In Example 2, the first channel coding bit block of input bits of the first block by a bit in the first bit sub-block bit, a second bit sub-blocks of bits, and the third bit subblock the bits. The number of bits in the first block of bits is L, the number of bits of the first sub-block of bits of L1, the number of bits of the second sub-block of bits is L2. The base station calculates the number of bits to obtain the third bit in accordance with the sub-block L, the L1 and L2 is the L-L1-L2. The third bit in the bit subblock bits for freezing. Freezing the default for a bit having a bit. The configuration of the base station number of rows and columns are the L switch matrix (Permutation Matrix) P, the sub-block of the first bit, the second bit sub-block and the sub-block concatenation third bit length to give L bit sequence, then the bit sequence ...
Embodiment 3
[0197] Embodiment 3 illustrates a schematic diagram of a mapping relationship between a first bit of average block, a second ratio of a sub-block, and a third bit, such as attached. image 3 Indicated.
[0198] In Example 3, the number of bits in the first bit larger is L, the number of bits in the first bit, the number of bits, the number of bits in the second ratio is L2, the third bit of the specion block The number of bits is L-L1-L2. The bits in the first ratio are corresponding to the L1 subchannel, and the bits in the second ratio correspond to the L2 subchannel one by one, and the bits and L-L1 in the third ratio block. -L2 subchannel one or one. The channel capacity corresponding to any one subchannel in the L1 sub-channel is higher than the channel capacity corresponding to any one of the L2 subchannels, and any of the L2 subchannels corresponds to any of the subchannels. The channel capacity is higher than the channel capacity corresponding to any one of the subchannels ...
