The original input block and the interleaved input block are encoded to obtain a codeword block, wherein the original input block is interleaved using an interleaver of size K′ and a permutation π(i)=(fi×i+f2×i2)mod K′, where 0≦i≦K′-1 is the sequential index of the symbol positions after interleaving, π(i) is the symbol index before interleaving corresponding to position i, K′ is the interleaver size in symbols, and f1 and f2 are the factors defining the interleaver. The values of K′, f1, f2 are taken from at least one row of a table. The codeword block is transmitted through the channel.

摘要： A method and apparatus for decoding data is provided herein to show how to turbo decode LDPC codes that contain a partial dual diagonal parity-check portion, and how to avoid memory access contentions in such a turbo decoder. During operation, a decoder will receive a signal vector corresponding to information bits and parity bits and separate the received signal vector into two groups, a first group comprising signals corresponding to the information bits and one or more parity bits, a second group comprising a remainder of the parity bits. The first group of received signals is passed to a first decoder and the second group of received signals is passed to a second decoder. The decoders are separated by an interleaver and a deinterleaver. Iterative decoding takes place by passing messages between the decoders, through the interleaver and the deinterleaver, and producing an estimate of the information bits from the output of the first decoder.

摘要： Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

摘要： A method and apparatus for rate matching is described. During operation of a transmitter, multiple data streams are received and individually interleaved with a permutation of a same length KΠ. A permutation (πp0) of a second stream is the same as a permutation (πsys) of a first stream and a permutation (πp1) of a third stream is different from the permutation of the first stream. Each element of πp1 is derived from the corresponding element of πsys. The plurality of interleaved streams are multiplexed to form a circular buffer. Finally, data is transmitted from the circular buffer.
