A communication system includes a central cloud server that detects the presence of an active sync path at each of a first edge device and a second edge device, where the first edge device is arranged at a first location at a vehicle and the second edge device is arranged at a second location of the vehicle. The central cloud server further determines a dominant edge device and a non-dominant edge device from the first edge device and the second edge device. The central cloud server further elects the determined dominant edge device from the first edge device and the second edge device to service one or more user equipment (UEs) in the vehicle, which improves performance in terms of data throughput and signal-to-noise ratio (SNR) of one or more UEs present in the vehicle by effectively controlling cooperation between two edge devices arranged in the vehicle.

The telecommunications systems, software, and methods are for power-efficient coordinated multipoint transmission, particularly in millimeter-wave small cells. The systems, software, and methods apply portfolio theory to determine an allocation of power to a plurality of transmitters in communication with one or more receivers in a joint transmission configuration, such as a MMW or BF-MMW joint transmission configuration. The systems, software, and methods apply portfolio theory to determine an allocation of power to a plurality of transmitters such that a mean received power, associated with a certain level of variance, is maximized, or the variance of received power, associated with a certain level of mean received power, is minimized.

Methods and apparatuses for same power transmissions. The method includes receiving first information indicating use of a same power for transmission of a channel over more than one slot and second information indicating use of a same power, after a change in power, for transmission of the channel over more than one slot. The method further includes determining a first number of consecutive slots, a second number of consecutive slots, from the first number of consecutive slots, for transmission of the channel with a same power, and a third number of consecutive slots, from the first number of consecutive slots and after the second number of consecutive slots, for transmission of the channel with a same power. The method further includes transmitting the channel with a first power in slots from the second number of consecutive slots and a second power in slots from the third number of consecutive slots.

Examples include techniques for determining power offsets of a physical downlink shared channel (PDSCH). In some examples higher and physical layer signaling may be provided to user equipment (UE) by a base station such as an evolved Node B to enable the UE to determine power offset values for a multiplexed PDSCH having a serving PDSCH and a co-scheduled PDSCH transmitted via use of same time and frequency resources. The determined power offset values for use by the UE to demodulate the serving PDSCH and mitigate possible interference caused by the co-scheduled PDSCH. Both the UE and the eNB may operate in compliance with one or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) supporting full duplex communications may determine that a set of downlink messages to be transmitted from a base station to the UE overlaps in time with a set of uplink messages to be transmitted from the UE. Accordingly, the UE may determine a downlink transmission power adjustment value for the set of downlink messages. In some examples, the base station may indicate the downlink transmission power adjustment value to the UE via radio resource control (RRC) signaling, a downlink control information (DCI) message, or both. The UE may transmit the set of uplink messages while simultaneously receiving the set of downlink messages with a transmission power that corresponds to the downlink transmission power adjustment value. Adjusting the transmission power for the set of downlink messages may reduce self-interference at the UE, the base station, or both.

Other embodiments are disclosed.
