Abstract: Methods and apparatuses for channel and interference measurement. A method for operating user equipment (UE) includes receiving, from a base station, configuration information for a channel measurement resource (CMR) and N interference measurement resources (IMRs) and configuration information for a channel state information (CSI) reporting. The CSI reporting configuration information indicates a selection of a signal-to-interference-plus-noise ratio (SINR). The method further includes receiving reference signals associated with the CMR and the N IMRs, measuring the reference signals for calculating the CSI reporting, and transmitting the CSI reporting. The CSI reporting includes M SINRs each associated with an interference hypothesis. N is an integer greater than or equal to 2. M is an integer greater than or equal to 1. The CMR is a synchronization signal block (SSB) or a non-zero power channel state information reference signal (NZP CSI-RS). The N IMRs are NZP CSI-RSs.

Abstract: A method for congestion control in a data communication protocol employing acknowledged communication may include measuring a flight size. A transmission rate may be measured. A trend of the flight size may be determined. A trend of the transmission rate may be determined, and the trend may be derived from a transmission rate gradient calculation, in which either the transmission rate measurements or the transmission rate gradient calculations or both may be filtered to reduce their temporal variability. Whether there is a congestion may be detected according to the determined trend of the transmission rate and the trend of the flight size. Upon detection of the congestion, a change may be made from a current congestion control state to a new congestion control state. Data may be transmitted while respecting a maximum amount of unacknowledged data which the transmitting node may transmit. An apparatus is also disclosed.
