Switching between channel estimation modes at a user equipment

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• determine an actual power delay profile (PDP) associated with a channel between the UE and a network node, wherein the actual PDP indicates an averaged power level of the channel over a period of time;
• determine whether a channel estimation mode switching event is satisfied;
• and
• switch, based at least in part on the channel estimation mode switching event being satisfied, between a first channel estimation mode based at least in part on the actual PDP and a second channel estimation mode based at least in part on a template PDP,
• wherein the first channel estimation mode is more accurate than the second channel estimation mode before switching, and the second channel estimation mode is more accurate than the first channel estimation mode after the switching.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
• determine an actual power delay profile (PDP) associated with a channel between the UE and a network node, wherein the actual PDP indicates an averaged power level of the channel over a period of time;
• determine whether a channel estimation mode switching event is satisfied;
• and
• switch, based at least in part on the channel estimation mode switching event being satisfied, between a first channel estimation mode based at least in part on the actual PDP and a second channel estimation mode based at least in part on a template PDP,
• wherein the first channel estimation mode is more accurate than the second channel estimation mode before switching, and the second channel estimation mode is more accurate than the first channel estimation mode after the switching.

An apparatus for wireless communication, comprising:

• means for determining an actual power delay profile (PDP) associated with a channel between the apparatus and a network node, wherein the actual PDP indicates an averaged power level of the channel over a period of time;
• means for determining whether a channel estimation mode switching event is satisfied;
• and
• means for switching, based at least in part on the channel estimation mode switching event being satisfied, between a first channel estimation mode based at least in part on the actual PDP and a second channel estimation mode based at least in part on a template PDP,
• wherein the first channel estimation mode is more accurate than the second channel estimation mode before switching, and the second channel estimation mode is more accurate than the first channel estimation mode after the switching.
