    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.

    摘要: For range expansion, a determination to enter range expansion may be made based on a signal strength differential for user equipment (UE) communications between a first class of base stations and a second class of base stations. If the signal strength differential is beyond a certain threshold, range expansion may be implemented. In range expansion, a signal is transmitted, on a resource coordinated with at least one of the first class of base stations, from one of the second class of base stations to the UE which could experience dominant interference from one of the first class of base stations if coordination were not performed. Transmission power may be reduced from one of the first class of base stations on that resource. The second signal may be transmitted within the region of the Physical Downlink Shared Channel.

    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.
