    摘要： 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.

    摘要： Techniques are provided for the suppression of reference signal transmissions to enable sensing in cognitive radio communications. In one example, there is provided a method, operable by a network entity (e.g., evolved Node B), that may involve communicating with another network entity to determine parameters of a quiet period, the parameters comprising at least one of when the quiet period occurs and duration of the quiet period. The method may involve transmitting a reference signal in a first channel exclusively during a first plurality of subframes of a first frame period, wherein the first frame period further includes a quiet period during which no signals are transmitted, and performing during the quiet period a sensing operation with respect to the first channel.

    摘要： Techniques for establishing and maintaining peer-to-peer (P2P) communication are described. In an aspect, P2P communication on an unlicensed spectrum may be established and maintained with network assistance. In one design, a user equipment (UE) may communicate with a wide area network (WAN) to establish P2P communication with at least one other UE on a first frequency band that is not licensed to the WAN. For example, the UE may receive an assignment of at least one frequency channel in the first frequency band for P2P communication. The UE may then communicate peer-to-peer with the other UE(s) on the at least one frequency channel. The UE may also communicate with the WAN to maintain P2P communication with the other UE(s), e.g., to switch to another frequency channel if necessary.
