Embodiment Construction

[0073] This application describes techniques for supporting cognitive radio communications. These techniques may be used in various wireless communication networks such as Wireless Wide Area Networks (WWAN) and Wireless Local Area Networks (WLAN). The terms "network" and "system" are often used interchangeably. A WWAN may be a CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and / or other network. A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), CDMA2000, and so on. UTRA includes Wideband-CDMA (WCDMA) and other variants of CDMA. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network may implement a wireless technology such as Global System for Mobile Communications (GSM). OFDMA network can implement such as evolved UTRA (E-UTRA), ultra-mobile broadband (UMB), IEEE802.16 (WiMAX), IEEE802.20, etc. wireless technology. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution ...

Abstract

Techniques are provided for control signaling and channel selection in cognitive Long Term Evolution (LTE). In one example, there is provided a method, operable by a mobile entity, that involves receiving, on a licensed channel, broadcasted channel usage information regarding at least one unlicensed channel used by one or more network nodes. The method further involves: performing a cell search procedure based at least in part on the channel usage information to select a given network node among the one or more network nodes; determining at least one random access parameter to be used in establishing wireless communication with the given network node, the at least one random access parameter being associated with a characteristic of the user device and determining a preferred downlink channel.
