ASSIGNING TIME DOMAIN RESOURCES TO FRAGMENTED ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING (OFDM) SYMBOLS
A method of wireless communication by a user equipment (UE) includes receiving, from a base station, signaling indicating an assignment of resources in a physical time domain to a set of contiguous symbols in a virtual domain. Each symbol of the set of contiguous symbols in the virtual domain may be associated with a respective orthogonal frequency-division multiplexed (OFDM) symbol of a respective one of a multiple sets of one or more contiguous OFDM symbols in the physical time domain. Each set of OFDM symbols may be associated with a respective slot of multiple slots in the physical time domain. The multiple sets of OFDM symbols may carry a single physical channel payload. The method also includes mapping the physical time domain resources to the multiple sets of OFDM symbols based on the assignment of the physical time domain resources to the set of contiguous symbols in the virtual domain. The method further includes receiving or transmitting the multiple sets of OFDM symbols on the physical time domain resources based on the mapping.

WIRELESS COMMUNICATION METHOD, USER EQUIPMENT, BASE STATION, AND SYSTEM
A wireless communication method includes transmitting, from a base station (BS) to a user equipment (UE), a configuration information indicating a resource used in transmission of a Channel State Information-Reference Signal (CSI-RS) by higher layer signaling; and receiving, with the UE, the CSI-RS from the BS based on the configuration information. The configuration information indicates a mapping for CSI-RS transmission using a single antenna port (AP) to a single resource element per a resource block. In other aspects, a UE, a BS, and a system are also disclosed.

Efficient design and implementation of synthesis of near-constant modulus (STORM) waveform
A transmitter includes a processor configured to convert a primary sequence of modulation symbols into a primary signal using a universal pulse shape. The processor is further configured to convert an auxiliary sequence of modulation symbols, created from the primary sequence, to an auxiliary signal using an altered version of the universal pulse shape. In addition, the processor is configured to combine the primary signal and the auxiliary signal to create a joint output signal.

Method for transmitting reference signal, and communication device
Disclosed are a method for transmitting a reference signal, and a communication device. The method is executable by a terminal device or a network device, and comprises: determining at least one time domain resource unit for transmitting a reference signal; and transmitting the reference signal on the at least one time domain resource unit. Since the reference signal is transmitted on the at least one specific time domain resource unit rather than being transmitted by reusing a portion of subcarriers of a time domain resource unit for data transmission, a delay in transmission of the reference signal is reduced, thereby reducing a delay in data demodulation or CSI measurement performed on the basis of the reference signal, and reducing control signaling overhead for indication of a rate matching resource and complexity of performing rate matching.
Methods and apparatus for supporting frequency division multiplexing of multiple waveforms
Aspects of the disclosure relate to methods and apparatus of wireless communication to support frequency division multiplexing (FDM) of multiple waveforms. The methods and apparatus schedule FDM symbols where the scheduling of the FDM symbols is selectively based on one or more waveform parameters during a time interval when the FDM symbols are transmitted. The FDM symbols are then transmitted over the time interval. Further aspects also include the reception of the FDM symbols in a receiver where the waveform parameters are applied for decoding based on application of the waveform parameters.
