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.

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

Examples refer to communication networks between user equipments, UEs, with other devices, such as a base station, BS. Examples refer to communication methods, e.g., for uplink, UL. A joint-resource pool (JRP) is defined.

Joint resource pools for uplink communications

A user device, UE, and a base station, BS, for a wireless communication system is described. Each is using a transmission scheme on a radio resource, and is to determine one or more parameters of a radio channel associated with the radio resource, and to adapt the transmission scheme by selecting an additional radio resource on the basis of the determined one or more parameters. Further a wireless communication system, comprising two or more of the above devices, corresponding methods and a computer program product are described.

Parameter based adaption of a transmission scheme on a radio resource

A wireless communication system includes one or more base stations, and one or more user devices, UEs. When running a certain application, the UE is to communicate over a session, like a PDU session, the session having associated therewith a current Quality of Service, QoS, profile, the current QoS profile selected form a plurality of different QoS profiles associated with the session. In case of a certain event, the wireless communication system is to replace the current QoS profile for the session by a new QoS profile for the session, the new QoS profile selected from a subset or all of the plurality of different QoS profiles associated with the session and/or one or more QoS profiles not yet associated with the session.

An apparatus configured for wirelessly communicating in a wireless communications network includes a wireless interface configured for wireless communication and a controller configured for controlling a beam pattern of the wireless interface and at least one communication parameter of the wireless interface. The apparatus is configured for receiving a locking signal indicating a request for locking at least a part of the beam pattern and the at least one communication parameter. The controller is configured for locking at least the part of the beam and the at least one communication parameter responsive to the locking signal.

Apparatus, measurement system and measurement setup and methods for testing an apparatus

The present invention is concerned with different novel concepts for reducing latency in data transmission. These concepts may be exploited by a transceiver configured to perform wireless data communication with a third party device by aggregating time division duplex carriers having different temporal distribution of uplink times and downlink times. These concepts may further be exploited by an apparatus configured to perform data transmission or reception via allocations of transmission resources of aggregated carriers in units of transmission time intervals into which the aggregated carriers are subdivided, wherein the aggregated carriers are temporally subdivided into the transmission time intervals in a temporal grid, respectively, wherein the aggregated carriers' grids are temporally mutually offset.
