By defining more SCS options and Discrete Fourier Transform ('DFT') options for transmissions in future networks, there arises cause to select from among the options, with aspects of the channel as guidance for the selection. In addition, new CP designs may be defined for use with the new SCS options and the new DFT options along with methods of selecting a CP design appropriate to a particular situation. The new CP designs may be shown to have smaller CP overhead when compared to the known CP designs used for known combinations of an SCS option with an FFT size option. New sampling frequency design options and new system basic timing options may also be defined, along with methods of making appropriate selections from among these options. Control signaling using higher layers may be used to distribute configuration options that include multiple SCS options, CP duration options, sampling frequency options and DFT size options per sub-band. Later, layer 1 signaling may be used to specify a particular option from among the multiple options.

Numerology schemes and system basic timing for future networks

A reference sequence may be transmitted in wireless communication, e.g. in order to perform channel estimation. The use of a reference sequence introduces overhead. In some embodiments, the subcarrier spacing (SCS) of the multi-carrier symbols (e.g. OFDM symbols) used to transmit one or more reference sequences is different from the SCS of the multi-carrier symbols used to transmit information (e.g. data). In some embodiments, an original reference sequence may be spread over multiple multi-carrier symbols, with each multi-carrier symbol carrying a respective reference sequence that is a portion of the original reference sequence. The technical benefit is possibly improved channel estimation because the original reference sequence is spread in time, but with the same overhead (in terms of total occupied time of reference symbols) as transmitting all of the original reference sequence at the same time.

Systems and methods for configuring semi-persistent scheduling (SPS) transmission are disclosed. An example method performed by a wireless device includes: transmitting, to a user equipment, a radio resource control (RRC) signal comprising a time and frequency configuration for semi-persistent scheduling (SPS); and transmitting, to the user equipment, an information block via a physical downlink shared channel (PDSCH) configured based on the time and frequency configuration for SPS, the information block comprising signaling indicating at least one of: a modulation and coding scheme (MCS) for a subsequent transmission, a transmit power control command (TPC) for physical uplink control channel (PUCCH), PDSCH-to-HARQ feedback timing indicator, and PUCCH resource indicator.

Methods and apparatuses are disclosed for semi-persistent scheduling and configured grant transmission configurations. An example method, which is performed by a communication device, includes the steps of: transmitting, to a user equipment (UE), a radio resource control (RRC) signal or activation downlink control information (DCI) signal for semi-persistent scheduling (SPS) or configured grant (CG) transmission configuration; and transmitting, to the UE, a physical layer control signal comprising an indication of one or more parameters for SPS or CG transmission.

A method for transmitting data over a SL data channel wherein a transmit UE and a receive UE are each semi-statically provided with a CG configuration such that a CG configuration indication does not have to be transmitted in association with each individual data transmission during a duration that the CG configuration is applied.

Sidelink configured grant resource configuration and signalling

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.

Method and apparatus for sending SRS

Methods and apparatuses for transmission of k repetitions over a channel are described. Repetition formats for the transmissions include options for slot-based repetition, mini-slot based repetition, intra-slot frequency hopping, inter-slot frequency hopping, data splitting, data switching, and DMRS sharing, among others. In some examples, intra-slot frequency hopping is performed. A first repetition of the k repetitions is sent over the channel, starting from a first symbol within a first slot, and using a first set of frequency resources. A second repetition of the k repetitions is sent over the channel, following the first repetition and starting from a second symbol within the first slot, and using a second set of frequency resources.
