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： Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.

摘要： Systems and methodologies are described that facilitate indicating a loss of channel quality on a component carrier of a plurality of component carriers. A UE can monitor configured component carriers to determine channel qualities associated therewith. The UE can transmit carrier quality information that includes the channel qualities of the plurality of component carriers. In addition, the UE can identify a component carrier experiencing a loss of channel quality and notify a base station of the component carrier with poor channel conditions. In one aspect, the UE can incorporate additional information into a scheduling request. In addition, the UE can generate a CQI report that contains the carrier quality information. Further, the base station, when a loss of channel quality occurs, can retry transmission on different carriers. Moreover, the base station can employ information provided by the UE when selecting a component carrier for a transmission.

摘要： Systems and methodologies are described that facilitate providing hybrid cell access points that can support closed subscriber groups (CSG) while providing at least a minimum level of service to wireless devices excluded from the CSG. Hybrid cell access points can allow non-member wireless devices to camp and receive paging signals. Upon receiving a request for resources from non-member wireless devices, hybrid cell access points can handover the non-member wireless devices to an access point that can serve the non-member wireless devices, provide a portion of resources compared to a disparate portion provided to member wireless devices, and/or the like. In addition, hybrid cell access points can vary levels of service and downlink transmission power to provide load balancing for access points. Varying levels of service and downlink transmission power can facilitate additional functionality, such as reducing transmission power to serve member devices while mitigating interference to non-member devices.
