    Abstract: Various techniques are presented to improve channel estimation in a wireless system, comprising: receiving, by a wireless device, an indication of a physical downlink channel configuration for receiving a physical downlink channel transmission, the physical downlink channel transmission including a demodulation reference signal (DMRS); transmitting an indication that the wireless device supports bundling DMRS signals across multiple slots; receiving a DMRS configuration, the DMRS configuration including a channel estimation bundle window, the channel estimation bundle window indicating that channel estimation may be performed across multiple slots; receiving a set of DMRS signals within the channel estimation bundle window, wherein a first DMRS signal of the set of DMRS signals is received in a first slot, and wherein a second DMRS signal of the set of DMRS signals is received in a second slot; and estimating a radio channel based on the first DMRS signal and the second DMRS signal.

    Abstract: The disclosure relates to Discontinuous Reception (DRX) based UE behavior. A user equipment (UE) is configured to perform operations comprising: obtaining a first DRX cycle; determining a second DRX cycle at least based on the first DRX cycle and a DRX cycle threshold, wherein the DRX cycle threshold is a highest value of DRX cycle that can support LEO (Low-Earth Orbit) cell measurement; and applying the second DRX cycle, comprising applying the second DRX cycle to measurement of at least one LEO cell of the serving cell and a neighbor cell, wherein at least one of the serving cell and the neighbor cell is a LEO cell.
