Time Domain Window Adaptation For Joint Channel Estimation And DMRS Bundling

An apparatus, comprising:

• at least one processor;
• and
• at least one non-transitory memory including computer program code, wherein the at least one non-transitory memory is storing instructions executed by the at least one processor to cause the apparatus to:
• determine one duration of scheduled transmissions for at least one of physical uplink control channels or physical uplink shared channels;
• determine at least one actual duration over which power consistency and phase continuity can be maintained,
• wherein each of the at least one actual duration is limited to a maximum time duration based on a corresponding user equipment capability comprising that frequency hopping can be enabled;
• determine one or more time-domain window duration based at least in part on the determined at least one actual duration to make the one or more time-domain window duration cover the one duration of the scheduled transmissions,
• wherein the determining comprises the one or more time-domain window duration is used to cover the determined at least one actual duration, and
• wherein each of the one or more time-domain window duration is adapted to correspond to the at least one actual duration;
• and
• based on the determined one or more time-domain window duration, perform at least one of modulation or demodulation of the scheduled transmissions;
• and
• based on an event causing power consistency and phase continuity to not be maintained, starting at least one of the one or more time-domain windows from a first orthogonal frequency division multiplexing symbol of the first scheduled transmission.

A method, comprising:

• determining one duration of scheduled transmissions for at least one of physical uplink control channels or physical uplink shared channels;
• determining at least one actual duration over which power consistency and phase continuity can be maintained,
• wherein each of the at least one actual duration is limited to a maximum time duration based on a corresponding user equipment capability comprising that frequency hopping is enabled;
• determining one or more time-domain window durations based at least in part on the determined at least one actual duration to make the one or more time-domain window durations cover the one duration of the scheduled transmissions,
• wherein the determining comprises the one or more time-domain window durations is used to cover the determined at least one actual duration, and
• wherein each of the one or more time-domain window durations is adapted to correspond to the at least one actual duration;
• and
• based on the determined one or more time-domain window durations, performing at least one of modulation or demodulation of the scheduled transmissions;
• and
• based on an event causing power consistency and phase continuity to not be maintained, starting at least one of the one or more time-domain windows from a first orthogonal frequency division multiplexing symbol of the first scheduled transmission.
