Abstract
In embodiments, an eNodeB (eNB) may include a sequence generator to identify an initialization parameter for a pseudo-random sequence. The initialization parameter may have a periodicity greater than one radio frame of a radio signal. The sequence generator may then generated a pseudo-random sequence based at least in part on the initialization parameter, and then generate a reference signal based on the pseudo-random sequence. The eNB may further include a transmitter that is coupled with the sequence generator and is to transmit the reference signal in a subframe of the radio signal.

1-22. (canceled)
An eNodeB (eNB) comprising:
- a sequence generator to:
- identify an initialization parameter for a pseudo-random sequence with a periodicity greater than one radio frame of a radio signal, wherein the radio frame includes a plurality of subframes;
- generate, based at least in part on the initialization parameter, the pseudo-random sequence;
- and
- generate, based at least in part on the pseudo-random sequence, a reference signal;
- and
- a transmitter coupled with the sequence generator, the transmitter to transmit the reference signal in a subframe of the one radio frame.
A method comprising:
- identifying, at a base station, an initialization parameter for a pseudo-random sequence with a periodicity greater than one radio frame of a radio signal, each radio frame comprising a plurality of subframes;
- generating, at the base station, based at least in part on the initialization parameter, the pseudo-random sequence;
- generating, at the base station, a reference signal based at least in part on the pseudo-random sequence;
- and
- transmitting, at the base station, the reference signal in a subframe of the plurality of subframes.
One or more computer readable media comprising instructions, when executed by one or more processors, cause a user equipment of a long term evolution (LTE) network to:
- identify an initialization parameter for a pseudo-random sequence with a periodicity greater than one LTE radio frame, each LTE radio frame comprising a plurality of subframes received from an enhanced NodeB (eNB) of the LTE network;
- generate, based at least in part on the initialization parameter, the pseudo-random sequence;
- generate, based at least in part on the pseudo-random sequence, a cell-specific reference signal (CRS);
- and
- identify the CRS in a subframe of an LTE radio frame received from the eNB.
