Methods, systems and devices for providing transmission resources that achieve transmission diversity while reducing pilot signal overhead are described. An exemplary wireless communication method may be implemented in a wireless communication system in which transmission resources are allocated on a per physical resource block (PRB) basis, where a PRB corresponds to a two dimensional resource pattern comprising a first number of subcarriers along a frequency dimension and a second number time slots along a time dimension. The method includes logically dividing subcarriers in each PRB into an integer number of sub-groups of sub-carriers, wherein the integer number is greater than one, allocating, to a transmission, transmission resources corresponding to one or more of the sub-groups of subcarriers, performing the transmission in the wireless communication system.

The disclosure relates to a communication device, a base station and respective integrated circuits and methods for a communication device and a base station. The communication device comprises a transceiver which, in operation, receives, from a base station, a hopping pattern indicator, a hopping pattern being an order of a plurality of bandwidth parts by which a signal is to be received or transmitted in a plurality of transmission time intervals, TTIs, a bandwidth part being formed by at least one physical resource block. The communication device further comprises circuitry which, in operation, determines a hopping pattern to be applied based on the hopping pattern indicator. The transceiver, in operation, further receives or transmits the signal in the plurality of TTIs according to the determined hopping pattern.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may map a transport block (TB) across multiple component carriers (CCs) associated with at least one slot of time-frequency resources. The wireless device may transmit the TB based at least in part on mapping the TB. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. A device may receive a set of demodulation reference signals (DMRSs) over a multi-path channel on a set of resources in accordance with a reference signal pattern. The reference signal pattern may be associated with a non-uniform frequency spacing that results in a row-sampled Discrete Fourier Transform (DFT) matrix associated with the reference signal pattern having a lower coherence than other row-sampled DFT matrices. Additionally or alternatively, the device may receive a set of tracking reference signals (TRSs) over the multi-path channel. The set of TRSs may be specific to wide-area terrestrial broadcast services, single frequency network (SFN)-based broadcast services, multimedia broadcast multicast services (MBMSs), or the reference signal pattern. The device may perform channel estimation based on receiving one or both of the set of DMRSs or the set of TRSs over the multi-path channel.

A communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for Internet of Things (IoT) is disclosed. A method of a terminal in a wireless communication system is provided. The method includes receiving downlink control information (DCI) including frequency domain resource allocation information on a physical downlink control channel (PDCCH) from a base station, identifying an allocated resource for transmitting or receiving data based on the frequency domain resource allocation information, and transmitting or receiving the data on the allocated resource. When the frequency domain resource allocation information is based on a first bandwidth part of a first bandwidth and the DCI is for a second bandwidth part corresponding to a second bandwidth, the allocated resource is identified by applying a scaling factor based on the first bandwidth and the second bandwidth.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention relates to a method and device for decoding data by a base station in a wireless communication system, and the method of the present invention comprises the steps of: transmitting, by a base station, phase tracking reference signal (PTRS) allocation information, which includes PTRS port information and orthogonal cover code (OCC) information, to a terminal; receiving, from the terminal, a demodulation reference signal (DMRS) and a PTRS to which an OCC depending on the OCC information has been applied, so as to estimate phase noise; and compensating the phase noise to decode data received from the terminal.

A method performed by a transmitter in a wireless communication system is provided. The method comprises: identifying that a first parameter used for indicating a first puncturing pattern is set to be not present in a first frame based on predetermined condition; determining whether to operate in duplicate (DUP) mode; and in case that the transmitter determines to operate in the DUP mode, transmitting a second frame in the DUP mode, wherein data in a payload portion of the second frame is duplicated in frequency in the DUP mode.

Dynamic spectrum sharing (DSS) deployments are described, in which smaller-bandwidth frequency bands (e.g., of fourth generation long term evolution, or 4G LTE) are combined into larger total bandwidth spectrum which overlaps the (larger bandwidth) spectrum of a new radio frequency band. For example, two ten megahertz LTE frequency bands can be combined to provide twenty megahertz total spectrum, which can overlap with twenty megahertz 5G spectrum for use in LTE/5G DSS. The LTE downlink subframes of each LTE frequency band are time and frame structure aligned with each other and with the new radio frequency band's downlink subframes. For uplink communications, the physical resource blocks (PRBs) are scheduled to leverage new radio's extra available PRBs. Such enhanced DSS facilitates setting up a single DSS carrier (instead of multiple traditional DSS carriers), which provides relatively better downlink and uplink throughput, less layer management and other similar benefits.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may determine a grid allocation of single carrier resource blocks (SC-RBs) that defines a plurality of SC-RBs in a time domain and in a frequency domain. The first node may perform, to a second node, a frequency division multiplexed transmission associated with a single carrier waveform using one or more SC-RBs indicated in the grid allocation of SC-RBs. Numerous other aspects are described.
