Abstract
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.
Claims1
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 a macro cell eNB or a small cell eNB,
- wherein the first network element and the second network element both communicate on a same frequency band;
- and
- wherein the processor of the first network element is configured to:
- transmit only on a first portion in time of a Multimedia Broadcast multicast service Single Frequency Network (MBSFN) subframe and listen to a downlink subframe from the second network element on a remaining second portion in time of the MBSFN subframe to maintain synchronization, wherein the second network element is a macro cell eNB, and when the first network element is unable to synchronize with the second network element.
