Patent ID: 11950210
Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A user equipment comprising:
a receiver configured to receive a wireless orthogonal frequency division multiplexed (OFDM) positioning reference signal (PRS);
a memory; and
a processor, communicatively coupled to the receiver and the memory, configured to:
select a symbol subset of a symbol group of the OFDM PRS, wherein
the OFDM PRS comprises a slot of symbols comprising the symbol group, wherein the symbol group consists of a first symbol quantity of consecutive ones of the symbols, and the symbol group is fully staggered in frequency domain,
the symbol subset consists of a second symbol quantity of the symbols of the symbol group,
the second symbol quantity is smaller than the first symbol quantity,
the symbol subset is less than fully staggered in the frequency domain,
each of the PRS resource elements within the symbol group are offset based on a comb size, and
the selection of the symbol subset is based
on one or more metrics, and
on motion of the user equipment; and

measure the symbol subset without measuring at least one of the symbols of the symbol group that is outside of the symbol subset.
