Abstract
Systems and methodologies are described that facilitate sending and/or receiving user equipment specific reference signals (UE-RSs) in a wireless communication environment. A UE-RS pattern can be selected yielded etc. based upon a number of symbols from a subframe utilized for downlink transmission. At least one time domain component of the UE-RS pattern can vary based upon the number of symbols from the subframe utilized for the downlink transmission. For instance the at least one time domain component can be punctured time-shifted and so forth. Further UE-RSs can be mapped to resource elements of the subframe as a function of the UE-RS pattern. Moreover a UE can utilize the UE-RS pattern to detect UE-RSs on the resource elements of the subframe. Further the UE can estimate a channel based upon the UE- RSs.

2. The method of claim 1 , wherein the sub frame is a regular sub frame and all symbols from the subframe are identified as be utilized for the downlink transmission.
3. The method of claim 1, wherein the subframe includes a Downlink Pilot Timeslot (DwPTS) and the number of symbols from the subframe utilized for the downlink transmission are identified as being a number of symbols included in the DwPTS as configured.
4. The method of claim 1 , wherein the subframe is sent to a relay and includes one or more symbols reserved as gap symbols.
5. The method of claim 1, wherein a time domain component of the UE-RS pattern includes code division multiplexing (CDM) groups on a same set of symbols.
6. The method of claim 1, wherein frequency domain components of the UE-RS pattern are unchanged based upon the number of symbols from the subframe utilized for the downlink transmission.
7. The method of claim 1 , wherein the at least one time domain component of the UE-RS pattern is varied based upon the number of symbols from the subframe utilized for the downlink transmission by time-shifting the at least one time domain component of the UE-RS pattern.
8. The method of claim 7, wherein a set of time domain components of the UE-RS pattern are time-shifted by a common number of symbols.
9. The method of claim 7, wherein a set of time domain components of the UE-RS pattern are time-shifted by differing, respective numbers of symbols
