Abstract: For improved reception of PDCCH (physical downlink control channel) messages in 5G and 6G, each message can be preceded by a special demarcation, and optionally followed by another (preferably different) demarcation. For even better reception, the two demarcations may be configured as short-form demodulation references that exhibit two predetermined modulation levels of the modulation scheme, such as the maximum and minimum amplitude or phase levels. For optimal reception, one or both demarcations may be surrounded by gaps, consisting of a single resource element with no transmission. Downlink messages with such multi-functional demarcations may greatly simplify the task of user devices in receiving their control messages from the base station.

Abstract: A wireless device may receive packets according to a protocol, such as Bluetooth, and may rapidly react to receive an interfering RF packet instead of dropping the first RF packet and the interfering RF packet, to decrease message delay due to collisions in high device density environments.

The wireless receiver may detect the interfering RF packet by detecting one or more of: a specific resync byte sequence, an increase in RSSI, or a phase shift. Additionally, a wireless device may add the specific resync byte sequence to an RF packet of a standard protocol.

Abstract: A transmitter system includes a mapper that maps data bits and power information to N subcarriers.

A single-sideband (SSB) prep unit may remove the lower or upper sideband. A beam former modifies the phase and/or the amplitude of the orthogonal IF signal for transmission through multiple sub-antennas in a phased array antenna.

Abstract: Waveforms for wireless communication are shaped asymmetrically according to a complex-valued weighted overlap/add (WOLA) filter. A wireless communication device generates a waveform corresponding to a carrier. The device determines whether neighboring carriers are being used for wireless communication.

The wireless communication device then transmits the asymmetrically shaped waveform to maximize interference reduction and signal quality.
