Claim 22:
23. An apparatus, comprising a processing circuit, coupled with a storing circuit, wherein the processing circuit is configured to execute instructions stored in the storing circuit to cause the apparatus to:
receive a reference signal by using a time-frequency resource, wherein a time domain resource of the time-frequency resource comprises a symbol, wherein a frequency domain resource of the time-frequency resource comprises a first frequency domain resource group and a second frequency domain resource group, and wherein the reference signal is based on a first base sequence and a second base sequence, the first base sequence corresponding to the first frequency domain resource group and the second base sequence corresponding to the second frequency domain resource group;
wherein the first frequency domain resource group of the reference signal and the second frequency domain resource group of the reference signal correspond to two different frequency domain combs on a frequency domain resource that is on the symbol, wherein the frequency domain resource is within one or more resource blocks (RBs), and wherein each of the two different frequency-domain combs comprises subcarriers from each of the one or more RBs.
