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.
Claims24
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.
4 more elements
A method for synchronization comprising:
- synchronizing a first network element with a second network element;
- and
- maintaining 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.
3 more elements
A first network element comprising a processor configured to:
- synchronize with a 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 is further configured to:
