    摘要: Techniques for transmitting data and resource signals (RS) are provided. According to certain aspects, an access point may determine RS resource locations related to one or more access points in a CoMP set transmitting a common reference signal (CRS), map data transmissions initially over resources other than those related to the RS resource locations, and map remaining data transmissions over resources related to the RS resource locations. According to certain aspects, a wireless device may receive a signal from access points in a coordinated multiple point (CoMP) communication set comprising a common reference signal (CRS) superimposed over data, determine CRS locations in the signal that correspond to the CRS, and decode data from the signal based at least in part on the determined CRS locations.

    摘要: Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.

    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: User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.
