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： Techniques for supporting communication in an asynchronous TDD wireless network are described. In an aspect, downlink transmissions and uplink transmissions may be sent on different carriers in an asynchronous TDD wireless network to mitigate interference. In one design, a station (e.g., a base station or a UE) may send a first transmission on a first carrier in a first time period and may receive a second transmission on a second carrier in a second time period. The station may only transmit, or only receive, or neither in each time period. In one design, allocation of carriers for the downlink and uplink may be performed when strong interference is detected, e.g., by a base station or a UE. When strong interference is not detected, the first and second carriers may each be used for both the downlink and uplink.

摘要： Techniques for adjusting transmit timing of base stations and user equipments (UEs) in a wireless network are described. In one operating scenario, a femto base station communicates with a femto UE, and a macro base station communicates with a macro UE located within the coverage of the femto base station. In an aspect, the transmit timing of the femto base station may be delayed relative to the transmit timing of the macro base station, e.g., to time align downlink signals from the femto and macro base stations at the femto and macro UEs. In another aspect, the transmit timing of the femto UE may be advanced relative to the transmit timing of femto base station by an amount larger than twice the propagation delay between the femto UE and the femto base station, e.g., to time align uplink signals from the femto and macro UEs at the femto base station.

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： 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.

摘要： An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.
