摘要： A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

摘要： A method and apparatus are described that provides flexible spectrum usage by using a paired frequency division duplex (FDD) spectrum to enable dynamic access in television white space (TVWS), sub-leased spectrum or unlicensed spectrum, (e.g., industrial, scientific and medical (ISM) bands), in a femto cell environment or the like. Elastic FDD (E-FDD) enables femto cell operation in TVWS, sub-leased spectrum and/or unlicensed spectrum, either simultaneously with licensed spectrum or as an alternate channel to licensed spectrum. E-FDD enables dynamic asymmetric bandwidth allocation for uplink (UL) and downlink (DL) in FDD, and enables variable duplex spacing, (i.e., using FDD with minimum duplex spacing between DL and UL spectrum, or, using hybrid-FDD, (FDD in a time duplexed fashion), when a spectrum gap between the UL and DL spectrum is below a certain minimum threshold. Additionally, the signaling enhancements to implement E-FDD are also provided.

摘要： Methods and apparatus for spectrum coordination are described. A method of spectrum coordination includes a spectrum coordinator receiving a request for shared spectrum from a CRS that the spectrum coordinator supports. The request includes at least one minimum protection requirement. The spectrum coordinator determines protection criteria for the CRS based on the at least one minimum protection requirement received from the CRS. The spectrum coordinator sends the protection criteria for the CRS to a geo-location database for use in assigning shared spectrum to other CRSs that the spectrum coordinator does not support.

摘要： A dynamic spectrum management (DSM) engine may determine the channel quality of one or more channels associated with the DSM engine when packets are not being transmitted over the channels. For example, the DSM engine may trigger a channel quality measurement on a non-primary channel on a condition that a predetermined period of time has lapsed since the last activity associated with the non-primary channel. Channel quality measurement may be triggered via a data sending event on the non-primary channel such as sending a data frame on the non-primary channel. The DSM engine may perform respective quality measurements on multiple channels and store the respective quality values in a database. Time-averaged channel qualities for the channels may be computed based on the stored quality values for computing transmit power distribution of across the channels.
