The present disclosure relates to systems and methods for operating transceiver circuitry to transmit or receive signals on various frequency ranges. To do so, an electronic device may determine a receive delay between one or more messages received on different component carriers and may transmit the receive delay to a base station to update how communications are transmitted on one of the component carriers. The update made to at least one of the component carriers may compensate for the receive delay between the different component carriers. Compensating for the receive delay may improve operations that delay downlink communications to reduce a likelihood or stop simultaneous downlink and uplink communications by further adjusting for delays seen at an electronic device when communicating with base stations disposed at a different distances from the electronic device.

Transmission delay compensation for intra-frequency band communication

A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.

Reference signal and control information processing in 5G-NR wireless systems

An electronic device may be provided with wireless circuitry and control circuitry. The wireless circuitry may communicate with a wireless base station using a 5G New Radio (NR) communications protocol. The wireless circuitry may include a phased antenna array. The electronic device may perform antenna scaling operations in which the active antennas in the phased antenna array change over time to optimize wireless performance and power consumption. The electronic device may inform the base station when antenna scaling operations have occurred. This may allow the base station to compensate for power density discontinuities associated with the antenna scaling operations. If desired, the base station may break transmit and receive signal beam correspondence and the electronic device may use different antenna scaling settings for transmitting and receiving signals.

An apparatus for generating a radio frequency signal based on a symbol within a constellation diagram is provided. The constellation diagram is spanned by a first axis representing an in-phase component and an orthogonal second axis representing a quadrature component. The apparatus includes a processing unit configured to select one of a plurality of segments of the constellation diagram containing the symbol. The segment is delimited by two radially extending boundaries, wherein the two radially extending boundaries span an opening angle of the segment that is different from 90&#xb0;. The processing unit is further configured to calculate a first coordinate of the symbol with respect to a third axis, and a second coordinate of the symbol with respect to a fourth axis. At least one of the third axis and the fourth axis coincides with one of the two radially extending boundaries. The apparatus further includes a plurality of digital-to-analog converter cells configured to generate the radio frequency signal using the first coordinate and the second coordinate.

Apparatus and a method for generating a radio frequency signal

An apparatus for generating a transmit signal includes an up-conversion module and a delay module. The up-conversion module up-converts a first component signal of a multi-phase baseband transmit signal using a first oscillator signal and up-converts a delayed second component signal of the multi-phase baseband transmit signal using a second oscillator signal to generate a radio frequency transmit signal. The first oscillator signal and the second oscillator signal comprise an oscillator signal phase offset so that an edge of the second oscillator signal occurs earlier than a corresponding edge of the first oscillator signal. The delay module delays a second component signal of the multi-phase baseband transmit signal relative to the first component signal of the multi-phase baseband transmit signal by a predefined component signal delay to generate the delayed second component signal of the multi-phase baseband transmit signal.

Apparatus and method for generating a transmit signal

A multicarrier transmitter has a first mode, in which the transmitter is configured to transmit a first component carrier signal modulated onto a first carrier by using a first LO signal, and a second mode, in which the transmitter is configured to transmit the first component carrier signal modulated onto the first carrier and a second component carrier signal modulated onto a second carrier by using a second LO signal. The multicarrier transmitter is coupled to a controllable oscillator and configured to adapt a frequency of an LO signal output by the controllable oscillator dependent on the multicarrier transmitter being activated in the first or second mode to output the first LO signal or the second LO signal. For example, the multicarrier transmitter may be configured to switch between the first mode and the second mode while transmitting the component carrier signals.
