Small cell demodulation reference signal and initial synchronization

摘要

Described herein is a system with a first network element and a second network element. The first network element contains a processor configured to synchronize with the second network element; and maintain synchronization with the second network element. The first network element is a small cell eNB and the second network element is one of the following: a macro cell enhanced node-B (eNB); or a small cell eNB.

1. A system comprising:
a first network element; and a second network element, the first network element comprising a processor configured to synchronize with the second network element and maintain synchronization with the second network element, wherein the first network element is a small cell enhanced node-B (eNB) and the second network element is one of the following: a macro cell eNB or a small cell eNB, and wherein the first network element and the second network element both communicate on a frequency band, and wherein the first network element transmits on a first portion in time of a physical resource block (PRB) pair and listens to downlink data transmitted from the second network element to a user equipment on a second portion in time of the PRB pair to maintain synchronization.
