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: Techniques of generating CSI reports include designating at least one of the reports as a reference and the other reports as dependent on the reference. For example, a dependent CSI report may have a differential value of a CSI quantity rather than a raw value of the CSI quantity. Because generally for parameters in a CSI report, the differential quantity has a smaller range of values than the raw values of the CSI quantity, a quantization of the differential value of the CSI quantity will have fewer bits than the raw value; for example, for L1-RSRP, the raw value has 7 bits while the differential value has 4 bits. In another example, a dependent value of a CSI quantity is a flag indicating that the CSI quantity value is located in a reference CSI report.
