    Abstract: Apparatuses (including base stations and terminals), systems, and methods for supporting both wideband and narrowband communications are described. In one aspect, a base station supporting first type terminals operating on a first bandwidth and second type terminals operating on a second bandwidth is described, having an information formatter, a transceiver, and a controller. The information formatter generates a Low-end Master Information Block (L-MIB) and a Low-end System Information Block (L-SIB), which are transmitted by the transceiver to first type and second type terminals. The L-MIB includes control information on an L-subframe configuration for supporting a second type terminal and a sub-band configuration of the L-subframe, while the L-SIB includes information on downlink reception and uplink transmission of the second type terminal. When the base station receives a Random Access Channel (RACH) preamble request from one of the terminals, the base station performs the random access procedure.

The method includes transmitting to a base station in a Primary Cell (PCell) and a Secondary Cell (SCell), a TDD Uplink-Downlink (UL-DL) configuration of the PCell having a DL subframe super-set or UL subset that are common in the SCell and the PCell and a TDD UL-DL configuration differing from each other, receiving data at a first subframe in the SCell, and transmitting, when a UL subframe set of the SCell is a subset of a UL subframe of the PCell, a feedback corresponding to the data at a subframe predefined in association with the first subframe in the PCell according to the TDD UL-DL configuration of the SCell. The method supports both the self-scheduling and cross-carrier scheduling of the UE using carriers of different TDD configurations.

    Abstract: Methods and apparatuses for signaling pulse shaping in a wireless communication system. A method of BS includes determining a spectral extension index (SEIndex) and a frequency domain spectral shaping type index (FDSSTypeIndex) for at least one transmission time interval (TTI) and transmitting, to a UE, the SEIndex and the FDSSTypeIndex. The method further includes receiving, from the UE, uplink (UL) data based on a spectral extension (SE) ratio associated with the SEIndex and frequency domain spectral shaping (FDSS) values. The FDSS values are associated with the FDSSTypeIndex.

    Abstract: Methods and apparatuses for dynamically adjusting parameters of a modulation scheme and parameters of a digital pre-distorter (DPD) to pre-compensate for distortion effects of a power amplifier (PA). A user equipment (UE) comprises a modulator configured to generate modulation symbols from input bits according to an adjusted symbol constellation, a DPD operably configured to generate pre-distorted symbols, and a PA configured to amplify the pre-distorted symbols to generate transmission symbols that include distortion effects of the PA. The adjusted symbol constellation is adjusted from a target symbol constellation such that the generated modulation symbols pre-compensate for the distortion effects. The DPD is further configured to generate the pre-distorted symbols from the modulation symbols using a pre-distortion function to further pre-compensate for the distortion effects, and update the pre-distortion function such that a difference between the transmission symbols and a scaled version of the target symbol constellation is reduced.

    Abstract: Methods and apparatuses for multiple concurrent random access procedures. A method for operating a user equipment includes receiving first configuration for a random access (RA) procedure, initiating a first RA procedure on a cell based on the first configuration, and initiating a second RA procedure on the cell prior to completion of the first RA procedure. A method for a base station includes transmitting a first random access response (RAR) and a second RAR. The first RAR includes a first temporary cell radio network temporary identifier (TC-RNTI) and a first uplink grant. The second RAR includes a second TC-RNTI and a second uplink grant. The method further includes receiving a first PUSCH scheduled by the first uplink grant and a second PUSCH scheduled by the second uplink grant. The first PUSCH includes the first TC-RNTI. The second PUSCH includes only the first TC-RNTI or both the first and second TC-RNTIs.

    Abstract: Methods and apparatuses for UE initiated reporting in a wireless communication system. A method of operating a UE includes: transmitting UE capability information supporting a FTN; generating data modulation symbols including a set of zero symbols, wherein the data modulation symbols are up-sampled or zero-padded; performing, to obtain DFT output signal, a DFT spread operation on the up-sampled or the zero-padded data modulation symbols; performing, based on a target FTN compression rate and a SC allocation, a discarding or a down sampling operation on the DFT output signal, wherein the discarding or the down sampling operation generates a subset of DFT symbols; mapping the subset of DFT symbols to a set of SCs; and performing an IFFT operation on the subset of DFT symbols to obtain an FTN-DFT-S-OFDM signal including the target FTN compression rate comprising a positive rational number smaller than one.

    Abstract: Error-correcting performance of polar codes is improved by reducing low-weight codewords through partial repetition. A threshold for weights of rows with indices belonging to an information set is obtained in a polar coding generator matrix, and a smallest index of the information set with a weight less than or equal to the threshold is obtained. A first candidate index is selected based on a frozen index that is larger than the smallest index, and a second candidate index is selected based on information indices that are smaller than a largest candidate frozen index and that corresponds to a weight less than or equal to the threshold. Support of the first candidate index is determined to be distinct from support of the second candidate index in at least two elements, based on which at least one bit from the second candidate index is repeated to the first candidate index.
