Abstract: A client device for wireless communication includes a transceiver and a processor. The transceiver is configured to receive frequency resource information to indicate a set of frequency resources for a physical random access channel (PRACH) preamble transmission. The frequency resource information includes at least one of: an interlace information indicating at least one of an interlace of a block-interlaced frequency-division multiplexing (B-IFDM) allocation, a resource element allocation information indicating a subset of resource elements within each block of the at least one B-IFDM interlace, and a resource element spacing information, such that an at least one resource element within at least one block of the at least one B-IFDM interlace is allocated for the transmission of one PRACH preamble according to a tone-interlaced frequency-division multiplexing (T-IFDM) allocation. The resource element allocation is repeated in each block of the at least one B-IFDM interlace.

Abstract: A transmitting device and a receiving device are described for a wireless communication system. The transmitting device transmits one or more synchronization signals on a carrier to at least one receiving device. A frequency of a synchronization signal among the one or more synchronization signals is located on a first frequency raster, and a carrier frequency of the carrier is deployed on a second frequency raster. The frequencies of two different synchronization signals among the one or more synchronization signals are located on different frequency positions in the first raster. The transmitting device transmits an indication of the carrier frequency to the at least one receiving device. The indication comprises at least one integer number. The receiving device derives the carrier frequency based on the at least one integer number.

Abstract: Embodiments provide methods and devices for data transmission and assignment of uplink control channel resources in an uplink FDD carrier, for enabling a terminal device to provide HARQ feedback for data transmitted in the downlink using carrier aggregation of a downlink FDD carrier and at least one TDD carrier. A method includes associating each downlink subframe in the downlink FDD carrier with an uplink control channel subframe in the uplink FDD carrier, associating each downlink subframe and special subframe in the TDD carrier with an uplink control channel subframe in the uplink FDD carrier, assigning uplink control channel resources in the uplink FDD carrier to the terminal device according to the associations, and transmitting data on said downlink FDD carrier and/or TDD carrier, to be received by the terminal device.

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: A transmitter and a method therein, configured for generating a synchronization signal for Device-to-Device (D2D) communication utilizing a Single Carrier-Frequency Division Multiple Access (SC-FDMA) waveform. The method includes determining, by a transmitter, a synchronization sequence du[l] modulating a set of subcarriers, where |du[l]|=|du[L−1−l]|, l=0,1, . . . , L−1, and |du[l]|=K, for a positive constant K, where u is a root index and L is a length of the synchronization sequence du[l]. The method further includes selecting the root index u from a set of root indices, and generating a synchronization signal for D2D communication utilizing an SC-FDMA waveform based on the determined synchronization sequence du[l] and the selected root index u.

Abstract: Embodiments of the present invention disclose a method and an apparatus for transmitting a synchronization signal. The method of the present invention includes: determining, by a first terminal, a D2D type, where the D2D type includes D2D discovery and D2D communication; and transmitting, by the first terminal, a synchronization signal according to the determined D2D type. Therefore, synchronization signals transmitted by terminals of different D2D types do not affect each other, avoiding that a second terminal detects and receives a synchronization signal that does not correspond to a D2D type of the second terminal and ensuring that user direct-connection communication can be performed correctly and efficiently.
