摘要： Methods of transmitting and receiving a set of bits are provided. In the transmitting method, some of the bits are mapped to modulated symbol, and some of the bits map to a subset of transmission resources out of a first set of transmission resources. The modulated symbol is transmitted using the subset of transmission resources. At the receiver, a modulated symbol is received using a subset of transmission resources. Some bits are recovered by demodulating the demodulated symbol, and some of the bits are recovered based on the subset of transmission resources over which the modulated symbol was received.

摘要： Methods are disclosed herein for generating and using outer codes based on non-equal length code blocks. In one embodiment, the outer code has a length equal to the length of the longest code block. This can be achieved by padding shorter code blocks such that they are also of equal length to the longest code block. The padding may be a standardized pseudo-random pattern or a standardized repeating pattern. In another embodiment, the outer code has a length shorter than the length of the longest code block. If a code block is received in error it may be recovered by using one or more of: the first outer code block, information bits of other code blocks and the parity bits of the failed code block.

摘要： Systems and methods are disclosed for providing H-ARQ transmissions in respect of a set of horizontal code blocks are combined in a code. Retransmissions contain vertical parity check blocks which are determined from verticals from the set of horizontal code blocks. Once all the vertical parity check blocks have been transmitted, a new set may be determined after performing interleaving upon either the content of the horizontal code blocks, in the case of non-systematic horizontal code blocks, or over the content of encoder input bits in the place of systematic horizontal code blocks. The interleaving may be bitwise or bit subset-wise. The retransmissions do not contain any of the original bits. In the decoder, soft decisions are produced, and nothing needs to be discarded; decoding will typically improve with each retransmission.

摘要： A reference signaling scheme is provided that is based on the use of a Zadoff Chu sequence with cyclic repetition, optionally code division multiplexing precoding, together with frequency domain spectral shaping (FDSS). A specific pulse shape design for the FDSS part of the reference signal scheme in some embodiments involves the use of a raised cosine pulse raised to the power of β. The new solution for generating reference signals has a Low peak average power ratio that matches the PAPR of SC-OQAM, good channel estimation performance, and the ability to implement CDM in the frequency domain to increase multiplexing gain.

摘要： Aspects of the present application provide methods and devices for time domain implementation of a single carrier waveform such as single carrier quadrature amplitude modulation (QAM) DFT-s-OFDM and single carrier Offset QAM (OQAM). A time domain implementation allows flexible symbol lengths, lower implementation complexity as a large IDFT operation is not required in the time domain and support for variable cyclic prefix (CP) length. An OQAM implementation utilizes a pre-processing step to convert a K complex QAM symbol sequence into a 2K OQAM symbol sequence and generates a sequence for transmission in the time domain as opposed to the frequency domain.

摘要： Aspects of the present disclosure provide a scheme for generating a multiple access (MA) signal that include mapping each of at least one stream of bits to generate a set of modulated symbols and transmitting the set of modulated symbols. The spreading signatures that are selected to map the at least one stream of bits are selected, at least in part, based on a set of compatibility rules. The spreading involves mapping each stream of bits using a respective spreading signature from a set of spreading signatures to generate a respective set of modulated symbols, wherein real spreading signature components of the spreading signatures are orthogonal to each other and imaginary spreading signature components of the spreading signatures are orthogonal to each other.

摘要： Communication resources for grant-free transmission are assigned to a User Equipment (UE) in a communication system. A diversity channel for uplink grant-free data transmission includes uplink grant free transmission resources assigned to the UE. The uplink grant-free transmission resources include one or more positions corresponding to partitions of an access region and one or more positions corresponding to resource elements (REs) in each partition of the access region. At a UE, an uplink initial data transmission and a subsequent transmission are transmitted by the UE in the diversity channel without receiving grant information from a network equipment. At a network equipment, the uplink initial data transmission and the subsequent transmission are received in the diversity channel without transmitting grant information to the UE.

摘要： An apparatus and method for transmitting data with conditional zero padding is provided. In accordance with an embodiment of the disclosure, a transmitter transmits data to a receiver by transmitting symbols such that each symbol is preceded by a cyclic prefix of a fixed length and the symbol conditionally includes enough zero padding to avoid ISI (Inter-Symbol Interference) between consecutive symbols. In some implementations, if the fixed length for cyclic prefixes is long enough to avoid ISI between consecutive symbols, then the symbols may omit zero padding. Otherwise, the symbols may include enough zero padding to avoid ISI between consecutive symbols. The zero padding may be zero tail or zero head.

摘要： Methods, devices and systems are provided for spreading and transmitting data in a wireless communications system such that the resulting waveforms that are transmitted have low Peak to Average Power Ratio and mitigate signal collisions between different devices. The method for spreading and transmitting data includes spreading data with a sparse spreading sequence having equally spaced non-zero subcarrier elements to generate multi-carrier spread data on subcarriers corresponding to the equally spaced non-zero subcarrier elements of the spreading sequence; and transmitting the multi-carrier spread data. Different spreading sequences may be assigned to different user devices. The different spreading sequences may differ in terms of sparsity level in the frequency domain, sparsity pattern in the frequency domain and/or pulse offset in the time domain. Multiple multi-carrier spread data streams may be received by a network node and decoded using Successive Interference Cancellation (SIC) techniques.
