1. A method for wireless communications, comprising:
- broadcasting beacon signals in an unlicensed spectrum at predetermined times from an evolved Node B (eNB), the beacon signals identifying the eNB and at least one associated attribute of the eNB that comprises an eNB deployment configuration for an eNB deployment with which the eNB is associated, wherein downlink signals from eNBs in the eNB deployment are synchronized and concurrently transmitted by the eNBs of the eNB deployment in the unlicensed spectrum.

Abstract
Methods and apparatuses are described in which an unlicensed spectrum is used for Long Term Evolution (LTE) communications. A first method includes broadcasting beacon signals in an unlicensed spectrum at predetermined times from an evolved Node B (eNB). A second method includes receiving beacon signals broadcast in an unlicensed spectrum at predetermined times from an eNB. The beacon signals may include downlink signals identifying the eNB and at least one associated attribute of the eNB.
