Communication of security key information

摘要

Technology for communicating security key information from a macro eNB is disclosed. Security key information associated with the macro evolved node B (eNB) may be determined. The security key information may be used to cipher information communicated at the first eNB. A small eNB may be identified at the macro eNB to generate the security key information associated with the macro eNB for ciphering information communicated at the second eNB. The security key information may be communicated, from the macro eNB, to the small eNB for inter-Evolved Universal Terrestrial Radio Access (EUTRA) evolved node B (eNB) carrier aggregation.

主权项

1. A first node operable to communicate security key information to a second node, the first node having computer circuitry configured to:
determine a first security key associated with the first node, the first security key being used to cipher information communicated at the first node; identify the second node, at the first node, to receive a second security key, the second security key to be used to cipher information communicated at the second node; and provide the second security key to the second node, for inter-Evolved Universal Terrestrial Radio Access (EUTRA) evolved node B (eNB) carrier aggregation, the second security key being different than the first security key, wherein the first node and the second node are selected from a group consisting of a macro node, a base station (BS), a Node B (NB), an evolved Node B (eNB), a home eNB, a micro eNB, a baseband unit (BBU), a remote radio head (RRH), a pico node, a low power node, a remote radio equipment (RRE), or a remote radio unit (RRU).
