Embodiments of this application provide a conflict resolving method and a terminal device. When uplink transmission conflicts with sidelink transmission in time, the terminal device can resolve the data transmission conflict based on a ProSe per-packet priority (PPPP) of data on a sidelink and a limit, thereby satisfying data transmission requirements in Release 15 and subsequent Releases. The method is applied to terminal-to-terminal communication. A terminal device needs to transmit sidelink data on M first-type carriers and transmit uplink data on N second-type carriers, and M and N are positive integers. The method includes: determining, by the terminal device based on a PPPP of the sidelink data transmitted on the M first-type carriers and a first limit, to preferentially transmit the sidelink data on some or all of the M first-type carriers, or to preferentially transmit the uplink data on some or all of the N second-type carriers.

This disclosure describes systems, methods, and devices related to extended range modulation and coding scheme (MCS). A device may generate a first orthogonal frequency-division multiplexing (OFDM) signal to be transmitted in a frequency band. The device may generate a second OFDM signal to be transmitted in the frequency band, wherein the second OFDM signal is a duplicate of the first signal. The device may assign a reduced number of guard intervals (GIs) to the first OFDM signal and the second OFDM signal. The device may cause to send the first OFDM signal and the second OFDM signal using the frequency band.

A radio frequency system package may include waveguides and loading blocks. The loading blocks may include dielectric material having a high dielectric constant between 13 and 20. Additionally, the loading blocks may be made of mold, epoxy, or the like material, and the loading blocks may fit into a region cut out of the waveguides. Moreover, the loading blocks may lower the cut-off frequency for wireless communication otherwise provided by the waveguides without the loading blocks (e.g., 28 GHz). In particular, the loading blocks may facilitate communication in low mmWave frequencies, such as 24 GHz.

Methods, systems, and devices for wireless communications are described. Some wireless communications networks may implement aspects of a single frequency network (SFN), which may support multicast and broadcast transmissions. In some cases, a base station may use directional beamforming techniques to transmit a message to a user equipment (UE) using a first frequency configuration of the SFN. The base station may adjust the first frequency configuration to a second frequency configuration, and may transmit a retransmission of the message to the UE using the second frequency configuration.

An apparatus may determine a mode in association with frequency/beam hopping. The mode may be configured semi-statically through RRC signaling and/or dynamically through a MAC-CE. The apparatus may determine the mode based on the RRC signaling/MAC-CE in order to switch between different configurations of frequency and beam hopping for single-beam and multi-beam PUCCH transmissions. The apparatus is configured to receive a PUCCH resource IE for a PUCCH resource indicating a PUCCH resource intra-slot frequency hopping configuration. The apparatus is configured to determine whether multiple PUCCH beams are activated for the PUCCH resource. The apparatus is configured to determine a mode for frequency hopping and beam hopping for the PUCCH resource based on at least one of the PUCCH resource intra-slot frequency hopping configuration, or the determination whether multiple PUCCH beams are activated. The apparatus is configured to transmit on the PUCCH resource based on the determined mode.

A communication system transmits data between communication nodes over a data transmission path. The system collects data from at least two different sources to create a fused data stream that is used as the input to a model for determining a frequency at which to transmit the data by skywave propagation. The data is transmitted between the communication nodes at the frequency determined by the model.

A method for communications is disclosed. The method includes determining, at a terminal device, status information of at least one of a first frequency band and a second frequency band. The terminal device is operable in the first frequency band and the second frequency band. The method further includes performing an allocation of multiple antennas of the terminal device between the first frequency band and the second frequency band, based at least in part on the status information.

Aspects of the disclosure relate to a user equipment (UE) configured to schedule resource management procedures including measurements and tracking loop procedures. In some examples, the UE includes at least one antenna pair and two or more receivers. The UE may be configured to determine a plurality of combinations of antenna pairs and component carriers, where each component carrier is associated with a particular frequency. The UE may further be configured to schedule measurements/tracking loop procedures to available receivers first and utilize a selection algorithm to select combinations of antenna pairs and component carriers and map the selected combinations to the remaining of the available receivers to perform tracking loop procedures. Other aspects, features, and embodiments are also claimed and described.
