    摘要: Systems and methodologies are described that facilitate utilizing different power control algorithms as a function of access terminal speed. For instance, instantaneous Channel Quality Indicator (CQI) reports can be inverted for slow moving access terminals while long-term geometry inversion (e.g., average CQI report inversion) can be utilized for quick moving access terminals. Speed of the access terminal can be estimated based upon time correlation of CQI values. Further, selection of implementing instantaneous CQI inversion or long-term geometry inversion can be based upon the estimated speed of the access terminal.

    摘要: Techniques for supporting communication in dominant interference scenarios are described. In an aspect, communication in a dominant interference scenario may be supported with cross-subframe control. Different base stations may be allocated different subframes for sending control information. Each base station may send control messages in the subframes allocated to that base station. Different base stations may have different timelines for sending control messages due to their different allocated subframes. With cross-subframe control, control information (e.g., grants, acknowledgement, etc.) may be sent in a first subframe and may be applicable for data transmission in a second subframe, which may be a variable number of subframes from the first subframe. In another aspect, messages to mitigate interference may be sent on a physical downlink control channel (PDCCH).

    摘要: Aspects are disclosed for multiplexing disparate wireless terminals. Resource blocks are mapped according to a hopping pattern. A first and second pair of physical resource blocks are allocated such that the first pair is associated with a first hopping index pair, whereas the second pair is associated with a second hopping index pair. For this embodiment, the first and second hopping index pairs are inversely symmetrical to each other. A pair of distributed resource blocks is also allocated. An assignment is then scheduled that includes a physical resource allocation and a virtual resource allocation. Aspects for operating a wireless terminal are also disclosed. Here, a communication that includes a resource allocation and a reference signal is received. A minimum resource allocation granularity is ascertained from the communication, and a joint channel estimation is based on the reference signal and is a function of the minimum resource allocation granularity.

    摘要: Systems and methodologies are described that facilitate mitigating intercarrier and intersymbol interference in symbol transmissions over wireless communications where transmitter and receiver may not be time synchronized. Symbol periods can be extended for transmitting symbols such that an original symbol can be transmitted with one or more duplicated symbols keeping phase continuous, blank symbols, and/or the like. In this regard, multiple receiver windows can be required to receive the symbol such that at least one window has a non-interfered symbol even though timing can be misaligned (e.g., in asynchronous communications channels). Alternatively, the receiver windows can be divided to allow similar receipt of symbols over multiple windows such that one window has a non-interfered symbol. Also, timing misalignment that leads to phase ramping in frequency is accounted for to allow proper demodulation of the symbol.

    摘要: Techniques for transmitting overload indicators over the air to UEs in neighbor cells are described. In one design, an overload indicator may be transmitted as a phase difference between at least one synchronization signal and a reference signal for a cell. In another design, an overload indicator may be transmitted as a phase difference between consecutive transmissions of at least one synchronization signal for a cell. In yet another design, an overload indicator may be transmitted by a cell on resources reserved for transmitting the overload indicator. In yet another design, an overload indicator may be transmitted by a cell on a low reuse channel or a broadcast channel. For all designs, a UE may receive overload indicators from neighbor cells, determine the loading of each neighbor cell based on the overload indicator for that cell, and control its operation based on the loading of the neighbor cells.

    摘要: Techniques for supporting data transmission via a relay station are described. In an aspect, data transmission may be supported using ACK-and-suspend. A transmitter station sends a first transmission of a packet to a receiver station. The transmitter station receives no ACK information for the first transmission of the packet and suspends transmission of the packet. The transmitter station thereafter receives an indication to resume transmission of the packet and, in response, sends a second transmission of the packet. In another aspect, different ACK timeline may be used when applicable. The receiver station may send ACK information in a designated subframe if available for use or in a different subframe. In yet another aspect, ACK repetition may be used. The receiver may send ACK information in multiple subframes to facilitate reception of the ACK information when the transmitter station is unable to receive one or more of the multiple subframes.
