An apparatus is provided for generating a transmission wave. The apparatus includes a plurality of antennas and a plurality of signal generators. The plurality of antennas has polarization diversity. The plurality of signal generators are each coupled to one of the antennas and configured to generate a continuous twisted wave by driving each of the antennas using independent, coordinated, and distinct sinusoidal waves, and having a twist frequency and a carrier frequency, the twist frequency lower than the carrier frequency. A method is also provided.

This disclosure provides systems, methods and apparatuses for a selection of one or more transmission and reception points (TRPs) within a multi-TRP system. In one aspect, a user equipment (UE) may transmit an indication of the selected TRPs and an indication of one or more beams that the selected TRPs may use to communicate with the UE based on a mismatch between a default operating frequency (DOF) of each TRP within the multi-TRP system and a DOF of the UE. For example, the UE may receive an indication of a DOF of each antenna port of the TRPs within the multi-TRP system and the UE may compare the indicated DOFs with a DOF of each antenna module of the UE. The UE may select to communicate with TRPs and select one or more ports that the selected TRPs may use to communicate with the UE based on the comparison.

A method of identifying individuals impaired by a psychoactive substance such as cannabis. The method includes presenting monocularly to a subject being tested; to each eye separately, a sinusoidal grating pattern of fixed spatial frequency with achromatic contrast or color contrast between grating stripes being temporally alternately modulated at a temporal frequency that ranges between 10 Hz and 60 Hz with a pattern of the contrast being such that the subject being tested can see a frequency doubling in the grating pattern.

A method for managing the telecommunication data traffic of a very high throughput satellite communication system wherein, for each satellite, the management of a so-called n+p site diversity and/or of a load diversity is implemented in a digital transparent processor in the satellite to guarantee the availability of the very high throughput communication system.

In some implementations, methods for selecting a set of beacons that are to be monitored by a mobile device may be employed. Specifically, an optimal set of beacons to monitor may be provided to a mobile device depending on particular groups of beacons that are in proximity to the mobile device, the distance from the mobile device to each of the particular groups of beacons, and the mobile device's position/movements as provided by a tracking service such as GPS. These techniques may ensure that the mobile device is not blind to the closest and/or most relevant beacons.

A base station can prevent deterioration of data channel application control accuracy due to influence of transmission power control to a control channel. In the base station, each encoding section performs encoding processing to an SCCH (Shared Control Channel) of each mobile station, each modulating section performs modulation processing to the encoded SCCH, an arranging section arranges the SCCH to each mobile station to one of a plurality of subcarriers which configure an OFDM symbol, and transmission power control section controls transmission power of the SCCH based on reception quality information reported from each mobile station. The arranging section arranges a plurality of the SCCH to be under transmission power control to one of the subcarriers so that combinations at resource blocks are the same.

Embodiment of this application provide methods and apparatuses for communicating downlink control information. One method includes: dividing, by a terminal device, target resources into M resource subsets; determining, by the terminal device, a resource set from the M resource subsets, wherein the resource set consists of N control channel bearing resource units, N≥2, at least two of the N control channel bearing resource units belong to different resource subsets of the M resource subsets, and at least two of the N control channel bearing resource units are not consecutive in the frequency domain, wherein each of the N control channel bearing resource units includes at least two resource element groups (REGs) that are consecutive in the frequency domain, and wherein each REG of the at least two REGs comprises a plurality of resource elements (REs); and receiving, by the terminal device, downlink control information on the resource set.
