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： 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.

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： Techniques for dynamically selecting subframe formats in a wireless network are described. In an aspect, a base station may dynamically switch between different subframe formats to support communication for different types of user equipments (UEs). In one design, the base station may declare a set of subframes as multicast/broadcast single frequency network (MBSFN) subframes for first/legacy UEs. The base station may send signaling conveying the set of subframes as MBSFN subframes to the legacy UEs. The base station may dynamically select the formats of the set of subframes for second/new UEs, e.g., on a per subframe basis. The format of each subframe may be selected from a plurality of formats, which may include at least one regular subframe format, at least one MBSFN subframe format, and/or at least one blank subframe format. The base station may send transmissions in the set of subframes based on the selected formats.
