COMMON REFERENCE SIGNAL PHASE DISCONTINUITY AND SEQUENCE INITIALIZATION

摘要

Methods, systems, and devices are described for supporting common reference signaling in wireless communications systems. Some configurations introduce a phase discontinuity between common reference signal (CRS) transmissions on different subframes. This may address issues that may arise when a reduced CRS periodicity is utilized. Indicators may also be transmitted from base stations to user equipment (UEs) to indicate whether phase continuity may be assumed or not. Some configurations may support CRS sequence initialization. These tools and techniques may utilize an extended CRS sequence periodicity, which may increase the number of CRS sequences transmitted by a cell.

1. A method for receiving common reference signals in a wireless communications system, the method comprising:
determining that a phase continuity may not be assumed between a first common reference signal (CRS) transmission and a second CRS transmission; and receiving the first CRS transmission and the second CRS transmission without maintaining the phase continuity.
