Abstract: A first communication device acting as a transmitter is configured to generate a communication signal comprising a set of interleaved discrete Fourier transform (DFT) precoded symbols which have been interleaved based on a permutation polynomial. The first communication device transmits the communication signal to a second communication device acting as a receiving device. Upon reception of the communication signal, the second communication device deinterleaves the set of interleaved DFT precoded symbols of the communication signal based on an inverse permutation polynomial.

Abstract: This application discloses a method for a hybrid automatic repeat request (HARQ) feedback of downlink data. A terminal receives downlink data of a physical downlink shared channel (PDSCH) and downlink data of a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH) from a base station. Then the terminal sends a hybrid automatic repeat request (HARQ) feedback codebook to the base station. A size of the HARQ feedback codebook is based on a state of a semi-persistent scheduling (SPS) PDSCH transmission and a total downlink assignment indicator in the downlink data of the PDCCH or the EPDCCH, and the HARQ feedback codebook comprises a HARQ bit for the SPS PDSCH transmission.

Abstract: The present disclosure relates to reference signal design methods and devices. In one example method, a first communication device obtains at least one sequence from a subset of sequences in a set of sequences and obtains at least one reference signal based on the obtained at least one sequence. The sequence is phase rotated during its generation, phase rotated in the frequency domain, or cyclically shifted in the time domain based on a constant value Δq. The first communication device transmits the reference signal to a second communication device.

Abstract: A network node and a user device are provided. The network node comprises: a processor configured to allocate a plurality of Physical Resource Blocks (PRBs) for a Physical Uplink Control Channel (PUCCH) having a PUCCH format defined for two or more PRBs, wherein the allocated plurality of PRBs are associated with a user device; a transceiver configured to signal allocation information to the user device, wherein the allocation information comprises a frequency location and a number of allocated plurality of PRBs. The user device comprises: a processor configured to determine uplink control information for one or more network nodes; a transceiver configured to transmit the uplink control information in a PUCCH to the one or more network nodes, wherein a plurality of PRBs are allocated for the PUCCH and wherein the PUCCH has a PUCCH format defined for two or more PRBs.

Abstract: This disclosure relates to techniques for synchronization signals. The synchronization signal comprise a primary synchronization signal (PSS) generated based on a PSS sequence and a secondary synchronization signal (SSS) generated based on an SSS sequence. The SSS sequence may be generated based on a first sequence corresponding to a first cyclic shift and a second sequence corresponding to a second cyclic shift. The first cyclic shift and the second cyclic shift are associated with Cell ID. The PSS sequence may be generated based on one of the first and the second sequences.
