Robust decoding of CoMP transmissions

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.

1. A method for wireless communications, comprising:
receiving a signal from access points in a coordinated multiple point (CoMP) communication set, the signal comprising a common reference signal (CRS) from one access point in the CoMP communication set superimposed, in a same resource block, over data from another access point in the CoMP communication set;
determining CRS locations in the signal that correspond to the CRS;deriving, based on a CRS transmission from a serving access point, rate matching schemes for CRS locations of non-serving access points in the CoMP communication set; anddecoding data from the signal based at least in part on the determined CRS locations and the derived rate matching schemes.
