    摘要： This document discloses a solution for occupying time-frequency resources for a wireless transmission. According to an aspect, a method comprises: determining time-frequency resources in a channel configuration, wherein the time-frequency resources is a combination of a first number of frequency resources and a number of time resources, wherein the first number of frequency resources is defined in units of consecutive resource blocks each having a determined number of resource elements; determining whether or not the first number of frequency resources is expressible as 2a·3b·5c where [a, b, c] are non-negative integers, and in case the first number of frequency resources is not expressible as 2a·3b·5c, determining a second number of frequency resources and a third number of frequency resources in the first number of frequency resources, wherein the second number of frequency resources is expressible as 2a·3b·5c, wherein the third number of frequency resources is not overlapping with the second number of frequency resources; occupying the second number of frequency resources within the number of time resources with information symbols and occupying the third number of frequency resources within the number of time resources for a wireless transmission; and generating and causing the wireless transmission comprising the occupied frequency resources.

    摘要： A method and apparatus to perform receiving at least one control signal in one of subframes or symbols of a sub-bandwidth part of signaling from a network node of a communication network; based on the at least one control signal of the sub-bandwidth part, performing timing and frequency synchronization for the communication network; and using the synchronized timing and frequency, maintain a connected state for communication operations with the communication network. Further, to perform configuring signaling including at least one control signal in one of subframes or symbols of a sub-bandwidth part of the signaling configured for a device, wherein the sub-bandwidth part of the signaling is configured for the device; and sending towards the device the signaling including the at least one control signal in the one of subframes or symbols of the sub-bandwidth part.

    摘要： Various communication systems may benefit from improved signaling. For example, communication systems may benefit from sending a multi-numerology reference signal that allows a receiving user equipment to perform simultaneous beamforming training, and channel estimation or channel state information acquisition. A method may include receiving at a user equipment a multi-numerology joint reference signal (610). The reference signal may include a reference signal for data channel demodulation or channel state information acquisition, and beamforming training. The method may also include performing simultaneous beamforming training and channel estimation or channel state information acquisition based on the multi-numerology joint reference signal (620).

    摘要： A method, apparatus, and a computer-readable storage medium are provided for cell-edge scheduling arrangement for high subcarrier spacing. In an example implementation, the method may include configuring, by a gNB, a first numerology parameter that enables at least symbol repetition and a modified cyclic prefix, and transmitting, by the gNB, a downlink signal/channel that is configured based at least on the symbol repetition and modified cyclic prefix. In another example implementation, the method may include configuring, by a user equipment (UE), a first numerology parameter that enables at least symbol repetition and modified cyclic prefix based at least on information received from a gNB, aligning, by the UE, fast Fourier transform (FFT) windows with boundaries of the repeated symbols, and processing, by the UE, a downlink signal/channel received from the gNB based at least on the aligning.
