    摘要： Systems and methods for processing a physical random access channel are provided. In some embodiments, a method can include: receiving a signal indicative of a strong user and a desired user on a physical random access channel; performing at least one of a single segment frequency domain detection or a multi-segment frequency domain detection on the signal indicative of a strong user and a desired user; generating a residual signal by cancelling out the signal indicative of a strong user; and obtaining a message transmitted by a user equipment by performing at least one of the single segment frequency domain detection or multi-segment frequency domain detection on the residual signal.

    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.
