Abstract: Systems, methods, apparatuses, and computer program products for enabling dynamic switching between multi-transmission reception point (multi-TRP) and single-transmission reception point (single-TRP). A method may include receiving a first indication in a downlink control information or a medium access control control element. The method may further include determining, at a user equipment, whether to apply a multi-transmission reception point physical uplink shared channel scheme or a single-transmission reception point physical uplink shared channel scheme for transmitting a transport block based on the first indication. In addition, the method may include interpreting at least one downlink control information field differently depending on whether it is determined that the single-transmission reception point physical uplink shared channel scheme or the multi-transmission reception point physical uplink shared channel scheme is applicable.

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: Techniques of performing CSI reporting include identifying a cluster of TRPs sharing common information in their CSI and transmitting a complete CSI report to a selected TRP of the cluster while transmitting partial CSIs reports to other TRPs of the cluster. Along these lines, in an example implementation, a UE receives a CSI-RS from a network, with the CSI-RS carrying a plurality of reference symbols from a plurality of TRPs. Based on the plurality of symbols, the UE generates TRP data representing CSI feedback for each of the TRPs. From the CSI feedback, the UE identifies, as a cluster, a subset of the TRPs that share common information within the CSI feedback. The UE then sends first identification data identifying the subset of the TRPs that make up the cluster to the network.
