Provided are a resource allocation method, a device, and a storage medium. The resource allocation method includes determining the number of resource blocks according to the length of a reference signal sequence, a roll-off factor of a frequency domain filter, and the number of subcarriers contained in each resource block and allocating frequency domain resources for a transmission band according to the number of resource blocks.

A method in a communication device for managing uplink transmissions from the communication device to a network node. The method includes obtaining a timing advance value, the timing advance value indicating a time period in which the communication device shall advance a first uplink subframe transmission to the network node, obtaining information about a location of a gap within the first uplink subframe, the gap having a predefined duration, the location of the gap occurring after the time period indicated in the timing advance value, and performing the first uplink subframe transmission after the predefined duration.

Methods, systems, and devices for wireless communications provide techniques for multiplexing, in a frequency domain, a synchronization signal block (SSB) and a control resource set (CORESET) to form a multiplexed block that is transmitted using a set of symbols. A base station may transmit multiple multiplexed blocks using multiple different beams with a switching gap provided between each multiplexed block that allows for switching of radio frequency (RF) components between different beams. The switching gap is longer than a duration of a cyclic prefix (CP) that is associated with each symbol of the set of symbols of each multiplexed block. Within one or more of the multiplexed blocks, an associated SSB may use a different waveform than the CORESET. The multiplexed blocks may use a common reference signal for both the SSB and CORESET.

A method performed by a communication node for transmission using a precoded multi-carrier modulation scheme in a wireless communications network is provided. The communication node splits a precoded multi-carrier symbol into at least a first symbol part and at least a second symbol part. Also, the communication node modulates the at least first and second symbol parts such that the first symbol part of the precoded multi-carrier symbol is used for transmission of a reference signal and the second symbol part of the precoded multi-carrier symbol is used for transmission of data and/or control information. Then, the communication node transmits the reference signal and the data and/or control information in the modulated precoded multi-carrier symbol.

Circularly pulse-shaped waveforms for communication systems are disclosed herein including a single carrier modulation in which pulse-shaping is performed using a circular convolution by the transmitter for various modulation schemes. A transmitter, related method, and corresponding receiver are also disclosed for demodulation of the single carrier circularly pulse-shaped signal and data extraction.

Methods and apparatus for frequency offset estimation are disclosed. In an exemplary embodiment, a method includes determining a demodulation reference signal (DMRS) frequency offset estimate from DMRS symbols in a received signal, and determining a cyclic prefix (CP) frequency offset estimate from cyclic prefix values in the received signal. The method also includes combining the DMRS and CP frequency offset estimates to determine a final frequency offset estimate. In an exemplary embodiment, an apparatus includes a DMRS frequency offset estimator that determines a DMRS frequency offset estimate based on DMRS symbols received in an uplink transmission, and a cyclic prefix (CP) frequency offset estimator that determines a CP frequency offset estimate based on cyclic prefix values in the uplink transmission. The apparatus also includes an offset combiner that combines the DMRS frequency offset estimate with the CP frequency offset estimate to generate a final frequency offset estimate.

Aspects described herein relate to resource block allocation for time domain single-carrier waveform processing in new radio (NR). Specifically, in an aspect, a guard band may be allocated for a single-carrier waveform in a time or frequency domain. In another aspect, a resource block may be allocated for a time domain single-carrier waveform.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a digital simulation to determine a precoding matrix indicator (PMI) associated with a digital reception beam. A base station may send, to the UE, a reference signal. The UE may perform a coarse beam search on the reference signal using non-oversampled digital reception beams. The UE may measure the signal strength of the reference signal for each of the non-oversampled digital reception beams and select the non-oversampled digital reception beam with the strongest signal. The UE may perform a refined beam search procedure on the selected beam by using a set of oversampled digital reception beams which correspond to the selected non-oversampled digital reception beam. The UE may determine the PMI associated with the strongest oversampled digital reception beam and send the PMI in a report to the base station.
