Abstract: Disclosed is a method comprising identifying or detecting, by a terminal device, at least two simultaneous uplink transmissions from the terminal device, wherein the at least two simultaneous uplink transmissions are at least partially overlapping in time on a same cell or component carrier; generating, by the terminal device, a single power headroom report (PHR) for the at least two simultaneous uplink transmissions using one uplink transmission of the at least two simultaneous uplink transmissions; and transmitting, by the terminal device and to a network node, the single PHR.

Abstract: Embodiments of the present disclosure relate to methods and apparatuses for sounding reference signal transmission. According to some embodiments, an apparatus is caused at least to: receive, from a network device sounding reference signal (SRS) configuration comprising one or more SRS resource sets; receive, from the network device, a message comprising an indication of which one of the one or more SRS resource sets is configured or enabled to follow or not follow corresponding one or more indicated transmission configuration indication (TCI) states from an activated TCI list for the apparatus; and transmit, to the network device, an SRS based on the indication. In this way, SRS resource sets may be dynamically detached to not follow specific TCI state and used for sounding the uplink channel in an efficient manner.

Abstract: Systems, methods, apparatuses, and/or computer program products for dynamically switching between or determining whether to apply single-TRP mode and/or multiple-TRP mode are provided. One method may include receiving, at a user equipment, configuration information indicating that multi-transmission reception point (TRP) physical uplink control channel (PUCCH) scheme could be applicable, and determining, at the user equipment, whether to apply the multi-TRP PUCCH scheme or a single-TRP PUCCH scheme for an uplink control information (UCI) transmission on a determined PUCCH resource.

Abstract: Various example embodiments relate to channel measurement and reporting. A user equipment may obtain an association between one or more transmission-reception points and one or more groups of resources for channel measurement. The user equipment may receive, from a network node, an indication indicating muting or unmuting of at least one of the one or more transmission-reception points. The user equipment may determine, based at least partly on the association and the received indication, one or more sets of the resources to be measured.

Abstract: Systems, methods, apparatuses, and computer program products for determining reference signal (RS) resources for pathloss calculations for multi-transmission reception point (TRP) uplink (UL) schemes are provided. A method may include detecting by a user equipment that a pathloss reference reference-signal is not provided for multi-transmission reception point uplink repetition or transmission scheme. The method may also include determining a first reference signal resource and a second reference signal resource as a result of the detecting. The method may further include calculating two pathloss values using the first reference signal resource and the second reference signal resource. Further, the method may include performing separate uplink power control for repetitions or transmissions toward different transmission reception points according to the two pathloss values.

Abstract: There is described a method to operate an apparatus of a radio communications network. The method comprises: receiving information characterizing at least one of a plurality of uplink handling rules; determining a plurality of uplink control information, wherein the determined uplink control information is associated with at least one uplink radio resource; selecting one of the plurality of uplink handling rules; mapping the plurality of determined uplink control information into an uplink control signal based on the selected uplink handling rule; and transmitting the uplink control signal via the at least one associated radio resource.
