EXTENSION OF USER EQUIPMENT-SPECIFIC REFERENCE SIGNALS FOR DOWNLINK PILOT TIME SLOT Russian patent published in 2014 - IPC H04L27/26 H04L5/00 H04W72/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication, particularly to use of a user equipment-specific reference signal (UE-RS) scheme, which is a function of the number of symbols used for downlink transmission in a wireless communication system. Disclosed is a technique which facilitates sending and/or receiving UE-RS in a wireless communication environment. A UE-RS pattern can be selected based on a number of symbols from a subframe used for downlink transmission. At least one time-domain component of the UE-RS pattern can vary based on the number of symbols from the subframe used for downlink transmission. For instance, the at least one time-domain component can be punctured, time-shifted, and so forth. Further, UE-RS can be transformed into resource elements of the subframe as a function of the UE-RS pattern. User equipment can use the UE-RS pattern to detect UE-RS on the resource elements of the subframe, and can also can estimate a channel based on the UE-RS.

EFFECT: facilitating coherent demodulation and decoding of symbols in a wireless communication receiver.
