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.
