An apparatus for a wireless communication network is described that has an antenna unit. The antenna unit includes a plurality of antennas or one or more antenna arrays each having a plurality of antenna elements. The apparatus communicates with one or more network entities of the wireless communication network, like a base station or another UE. The apparatus transmits to or receives from the network entity a reference signal, like a Sounding Reference Signal, SRS, or a Synchronization Signal Block, SSB, using one or more beams beamformed by the apparatus using one or more input parameters. The apparatus transmits a feedback to the network entity, the feedback indicating the one or more input parameters the apparatus uses for beamforming the one or more beams, and/or the apparatus is configured or preconfigured, e.g., by the network entity, with the one or more input parameters.

Iterative transmit refinement

An apparatus includes an antenna and a transceiver. The transceiver transmits a first signal via the antenna, the first signal including a unique identification of the apparatus and a request for receive information about the first signal at a receiver. The transceiver receives from the receiver a second signal via the antenna, the second signal including first information about a direction of arrival (DoA) of the first signal at the receiver and second information indicative of a location of the receiver.

Apparatus, system and method for improving position estimation and/or communication performance in a wireless communication network

A receiver is configured is configured to receive a data signal, the data signal having at least one data signal block, the data signal block having a predefined duration in the time domain, a number of symbols in the time domain and a bandwidth in the frequency domain, wherein the data signal block is received over a plurality of transmission intervals, wherein a length of one transmission interval is shorter than the duration of the data signal block so that a subset of the symbols of the data signal block is received over one transmission interval, and wherein the receiver includes a signal processing device configured to process the symbols of the data signal block which have been received over one transmission interval.

Data signal transmission in a wireless communication system with reduced end-to-end latency

A first transceiver for a wireless communication system according to an embodiment is to determine information on an occupancy of a transmission channel. Moreover, the first transceiver is to transmit the information on the occupancy of the transmission channel to a second transceiver. Furthermore, the first transceiver is to determine the information on the occupancy of the transmission channel and to transmit the information on the occupancy of the transmission channel to the second transceiver without having received from the second transceiver a ready-to-transmit message with which the second transceiver would inform the first transceiver that the second transceiver intends to transmit user data to the first transceiver.

User device and method with beam management enhancements

A device includes a wireless interface configured for wirelessly transmitting a signal to a receiver; and a precoder unit configured for obtaining a first data signal to be transmitted and a second data signal to be transmitted; and for performing a first multipath-precoding of the first data signal according to a first set of paths between the device and the receiver to obtain a first precoded signal; and for performing a second multipath-precoding of the second data signal according to a second set of paths between the device and the receiver to obtain and a second precoded signal; wherein the precoder unit is configured for generating the first precoded signal and the second precoded signal such that the second precoded signal is delayed with respect to the first precoded signal at the receiver. The device is configured for transmitting the first precoded signal and the second precoded signal.

Spatial multiplexing with single transmitter on wideband channels

A user device UE for a wireless communication with a plurality of wireless network elements includes a plurality of antennas. The plurality of antennas are configured to form a plurality of spatial or directional beams. The user device is configured to provide simultaneously a plurality of independent wireless communication links using the plurality of spatial or directional beams, wherein the user device is configured to provide a first wireless communication link with a first wireless network element using a first spatial or directional beam and to provide a second wireless communication link with a second wireless network element using a second antenna beam.

Multi-connectivity user device for wireless communication networks

The application relates to a communication device [e.g., UE] for communicating with one or more other communication devices using multiple-input-multiple-output, MIMO, communication, wherein the communication device is configured to:

Communication devices, communication coordinating devices, and communication methods

In a communication system, a transmitter is configured to change a transmission characteristic used for the communication with a receiver, wherein a receiver is configured to determine a reception quality of a communication link between the transmitter and the receiver and to transmit a feedback information to the transmitter indicating whether a reception quality has changed or in which direction the reception quality has changed, or whether a transmission characteristic should be maintained, wherein the transmitter is configured to further change the transmission characteristic used for the communication with the receiver in dependence on the feedback information received from the receiver.

1 bit signaling feedback to configure or change the settings of a communication system

A receiver receives and processes a data signal having at least one data signal block. The data signal block has a number of symbols in the time domain and a number of sub-carriers in the frequency domain. The data signal block includes a control region to provide control data to the receiver and a payload region to provide payload data to the receiver. Payload data is allocated to the control region of the data signal block.

Data transmission in a wireless communication system with reduced latency

Communication apparatus of a cellular communication network, wherein the apparatus is configured to receive a reference signal; and to estimate a phase estimate based on the received reference signal; and to provide a localization module with the phase estimate.
