摘要:
Techniques for sending an aggregated beacon in a cognitive wireless network are disclosed. A beacon device may segment beacon information and send beacon segments via a plurality of channels simultaneously. A certain information elements of the beacon information may be included in each beacon segment. Each beacon segment may include channel information for other beacon segments that are transmitted simultaneously. Alternatively, a discovery beacon may be transmitted in addition to a regular beacon. The discovery beacon may include information indicating an operating channel on which the regular beacon is transmitted. The discovery beacon may be transmitted using a predetermined channel bandwidth, with a smaller beacon interval than the regular beacon, or in a frequency hopping fashion. The discovery beacon may be sent on a channel selected based on a regulatory class and corresponding channel information. The discovery beacon may be transmitted on a side channel.
摘要:
Systems and methods are described generally related to the creation of a spectrum allocator (SA) function that can be used to dynamically assign/reassign the frequency of operation of a node operating in a wireless communication network. To permit LTE operation in license exempt (LE) bands, the radio resource management (RRM) system is enhanced to include an interface, which allows it to communicate with modules external to the RRM, such as a coexistence manager, policy engine and sensing toolbox.
摘要:
Method and apparatus for controlling cell congestion, the method comprising receiving a first indication from a wireless transmit/receive unit (WTRU) that indicates that the WTRU is a time tolerant device; determining, via an eNodeB, a first access class of time tolerant devices and a second access class of non-time tolerant devices; determining, via the eNodeB, that preventing one or more devices that belong to the first access class from accessing a cell can prevent the cell from experiencing congestion; and sending a second indication to the WTRU that the first access class is barred from accessing the cell due to cell congestion.
