Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of spatial adaptation for energy saving. The method comprises: receiving, at a first device from a second device, a change indication indicating at least one antenna port of which at least one antenna element is changed. The antenna port is active before and after the change. The method further comprises performing at least one of a measurement of at least one reference signal or a reception of a physical channel in consideration of the at least one antenna port. In this way, the first device may be informed about impact of spatial adaptation of the second device and is able to adapt the impacted channel state information measurement and/or reporting. As such, energy saving can be achieved.

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: Disclosed is a method comprising receiving a configuration from a base station, wherein the configuration comprises at least a first subset of power control parameters and a second subset of power control parameters. The first subset of power control parameters and the second subset of power control parameters are assigned to a physical uplink control channel resource. Uplink control information is transmitted or repeated at least to a first transmission reception point and to a second transmission reception point using the physical uplink control channel resource, wherein the first subset of power control parameters is used for transmitting or repeating to the first transmission reception point, and the second subset of power control parameters is used for transmitting or repeating to the second transmission reception point.

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: Systems, methods, apparatuses, and computer program products for enabling beam diversity for physical uplink shared channel (PUSCH) repetition under multi-transmission points (TRP). A method may include receiving, from a network, a configuration with at least one time offset to account for at least one delay on switching from one transmit beam to another transmit beam, wherein the configuration defines at least one rule applicable to the at least one time offset. The method may also include determining a need for the at least one time offset between consecutive repetitions based on the configuration and the use of transmit beams for the consecutive repetitions. The method may further include applying, based on the determination, the at least one time offset between the consecutive repetitions. Further, a time domain allocation of at least one repetition of the consecutive repetitions may be changed to accommodate the at least one time offset.
