    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: Providing for user equipment mobility in a multi-carrier wireless network deployment is described herein. By way of example, data pertinent to mobile cell selection can be shared among base stations operating on different carrier frequencies either over-the-air or via a wired backhaul, and distributed by a base station to mobile terminals served by the base station. In one aspect, the data can be distributed over a wireless channel reserved for inter-carrier association data, whereas in other aspects, the data can be unicast to particular mobile terminals served by the base station. This can reduce or avoid a need for individual mobile terminals to tune away to a non-serving carrier for inter-carrier association or handover determinations. Accordingly, gaps in signal analysis on a serving carrier can be reduced or avoided, improving overall quality of wireless communication in a multi-carrier environment.

    摘要: Systems and methodologies are described that facilitate guard bandwidth independent mapping and de-mapping of bandwidth in a wireless communication system. Broadcast signals can be created as if all bandwidth were available, and guard bandwidth can be initialized over the utilized bandwidth such to puncture the data existing in the guard bandwidth. Upon decoding the broadcast signal, size of the guard bandwidth can be predetermined or estimated allowing a center portion of the signal to be decoded without decoding the guard bandwidth. In this regard, the decoder of the signal need not find exact positions of the guard bandwidth as transforming and decoding the center portion can provide a substantial portion of the signal to interpret the signal.

    摘要: Techniques are provided for efficient allocation of frequency spectrum blocks. In one example, there is provided a method, operable by one or more network entities, for reallocating a portion of a first frequency band allocated to a first radio access technology (RAT) to a second RAT. The method may involve determining a migration block granularity for reallocating the portion of the first frequency band to the second RAT. The method may involve identifying spectrum block(s) of the determined granularity in the first frequency band. The method may involve aggregating the identified spectrum block(s) with a native carrier in a second frequency band allocated to the second RAT. The method may involve controlling of the aggregated spectrum block(s) via the native carrier for the second RAT.

    摘要: Techniques for transmitting power decision pilots are described. A transmitter (e.g., a base station or a UE) may transmit a power decision pilot to indicate a transmit power level that it will use on subsequent time-frequency resources. In one design, the transmitter may determine a set of time-frequency resources to use for transmitting the power decision pilot, determine the transmit power level for the power decision pilot based on the transmit power level to use for data transmission, and transmit the power decision pilot on the set of time-frequency resources to indicate the transmit power level to use for data transmission on the subsequent time-frequency resources. A receiver (e.g., a UE or a base station) may receive power decision pilots from a set of transmitters and may estimate channel quality that the receiver can expect on the subsequent time-frequency resources based on the power decision pilots.

    摘要: Systems and methodologies are described that facilitate communicating between access points using the same air interface as for serving wireless devices. Access points can communicate with one another over the air interface to exchange interference management messages related to negotiating and/or allocating resources among the access points or other messages. In addition, access points can prepare served wireless devices for time periods where the access points communicate with disparate access points over the air interface to mitigate confusion or radio link failure detection by the served wireless devices.

    摘要: Wireless communications methods and apparatus are described. A communications apparatus, e.g., a base station, measures interference information, e.g., other sector interference information. The communications apparatus generates a preamble which includes a plurality of pilot symbols and at least one of the pilot symbols includes interference information. In some embodiments, the preamble is part of a superframe structure, e.g., a recurring superframe structure, including the preamble and a plurality of frames, at least some of the frames used to convey traffic data. The communications apparatus transmits the preamble, thus broadcasting the interference information to access terminals in the vicinity. An access terminal receives the preamble including a plurality of pilot signals, at least one of the pilot signals including interference information. The access terminal recovers the interference information from the received preamble and controls signal transmission based on the recovered interference information.
