摘要： Techniques are provided for frequency spectrum sharing that allows secondary operators to access a frequency band of a primary operator without interfering with the primary operator's use of the band, while ensuring service continuity for devices of the secondary operators. For example, there is provided a method that may involve identifying an outage on a first channel of a plurality of channels of a spectrum, wherein each of the plurality of channels is allocated to one of a plurality of operators. The method may involve migrating all mobile stations in communication over the first channel of the plurality of channels to at least one other channel of the plurality of channels during the outage.

摘要： Techniques are provided for channel discovery. For example, there is provided a method operable by a mobile entity that may involve measuring beacon signals associated with the network. In one approach, the method may involve, in response to detecting an Authorized Shared Access (ASA) beacon signal on a frequency common to each network entity on a given ASA channel, extracting frequency information from the ASA beacon signal, wherein the ASA beacon signal comprises a single frequency network (SFN) beacon signal. In another approach, the method may involve, in response to detecting an ASA beacon signal on a frequency common to each network entity on a given ASA channel, extract frequency information from the ASA beacon signal, wherein timing correlates with an operating frequency for the ASA beacon signal.

摘要： Systems, methods and apparatuses are provided that facilitate selecting resources, such as time slots, subframes, etc., for performing bandwidth switching related to activating and/or deactivating one or more carriers. A data portion of one or more subframes can be selected for performing bandwidth switching. In addition, a device can determine whether one or more downlink grants are received in the one or more subframes, and can avoid selecting such subframes. The device can alternatively perform the bandwidth switching and request retransmission of the data portion. Additionally or alternatively, the device can determine a type of the one or more subframes and/or signals transmitted in the one or more subframes to determine whether to perform bandwidth switching in the subframes. The bandwidth switching can include changing a sampling rate, reconfiguring frequency filters, modifying a local oscillator, etc.

摘要： Aspects are disclosed for facilitating a timing alignment in a multicarrier system. In one aspect, at least one downlink timing associated with at least one downlink carrier is determined, and an uplink timing associated with an uplink group of carriers is ascertained based on at least one downlink timing and a timing offset associated with the uplink group of carriers. Each of the uplink group of carriers is then transmitted within a threshold value of the uplink timing. In another aspect, a downlink communication is transmitted to a wireless terminal via at least one downlink carrier. This embodiment further includes assigning a timing offset to an uplink group of carriers, and providing the timing offset to the wireless terminal via the at least one downlink carrier. An uplink communication is then received via the uplink group of carriers according to the timing offset.

摘要： Measurements are conducted on one or more carriers in a case where an access terminal supports reception on multiple carriers. Upon determining that an access terminal is capable of concurrently receiving on a given set of carriers, a measurement is conducted on one or more carriers of the set while receiving on or more other carriers of the set. Conversely, upon determining that an access terminal is not capable of concurrently receiving on a given set of carriers, a measurement is conducted on one or more carriers of the set while not receiving on or more other carriers of the set. In addition, data transfers to or from an access terminal on a carrier may be restricted (e.g., data transfers not scheduled or only low priority data transfers scheduled) during one or more subframes before or after the access terminal conducts a measurement on another carrier.
