    摘要： Certain aspects of the present disclosure propose methods for reporting information such as a maximum power spectral density to a serving access point after receiving overload indicators from one or more neighboring access points. The reported information may be multiplexed with other information (e.g., Channel Quality Indicator (CQI), Precoding Matrix Index (PMI), rank indication (RI) or acknowledgement (ACK)/negative acknowledgment (NACK) message for downlink data channel) before transmission to the serving access point. In addition, the information may be transmitted in a medium access control (MAC) packet data unit (PDU).

    摘要： Systems and methodologies are described that facilitate determining control region parameters related to a plurality of carriers and/or coordinated multiple point (CoMP) access points. Wireless devices can receive control region parameters related to the carriers or CoMP access points from a serving access point over control channel resources. Additionally or alternatively, wireless devices can assume all carriers or CoMP access points have substantially the same control region as indicated in a control format indicator channel from the serving access point or based on a configured value.

    摘要： Techniques for reporting timing information to facilitate data transmission on a downlink are described. A user equipment (UE) may receive signals from a plurality of cells available for data transmission to the UE. Each cell may have a different propagation delay to the UE. The UE may determine timing information based on the received signals and may report the timing information to one or more of the cells. The timing information may include a receive time of each cell at the UE. The UE may receive a data transmission from at least one cell, which can be selected from the plurality of cells, based on the timing information. The at least one cell may provide a coordinated or a non-coordinated data transmission. A coordinated transmission mode may be determined based on the timing information and can include, for example, a joint transmission, a coordinated beamforming, or a coordinated silencing.

    摘要： In 3GPP Release (Rel) 8, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) may be transmitted in six resource blocks, occupying, for example, the center 62 tones (i.e., subcarriers) of an LTE-A system, wherein the center tone may be skipped. In synchronous networks, cells may transmit their respective PSS and SSS on the same frequency at the same time, wherein strong cells may overshadow the weak ones. However, strong cells may not be the serving cell for a user equipment (UE), particularly in a heterogeneous network. Traditionally, interference cancelation, an enhanced receiver technique, has been used, wherein the UE may first find the strong cells and cancel them out to find the serving cell. However, due to propagation delay and synchronization uncertainty, a timing offset may exist among cells, even in synchronous networks. Therefore, systems and methods are disclosed, providing for improved handling of the timing offset among different cells by applying a time domain cancelation.

    摘要： A method for ranking signals isolates and cancels neighboring cells using layering. Received signals from various cells are grouped into layers, with each layer comprised of received signals which are comparable within a particular metric (such as signal strength). The signals within a particular layer may also be ranked according to a desired metric. At the beginning of a cancellation cycle the UE may perform the layering and ranking. Once the layering and ranking has been performed the UE may continue to use the layering and ranking for later rounds of cancellation, freeing up processing resources that would otherwise be dedicated to repeated ranking of received signals. After a period of time, the cancellation cycle may repeat and the layering and ranking may be performed again.
