Positioning location for remote radio heads (RRH) with same physical cell identity (PCI) |
摘要 |
A method of wireless communication includes receiving position location reference signals (PRSs) from multiple remote radio heads (RRHs) and a macro eNodeB having a same physical cell identity (PCI). Each PRS is a same PRS. Additionally, the PRSs from the multiple RRHs are received on subframes that are different from subframes used by the macro eNodeB. Furthermore, each PRS does not indicate a source of transmission. The method also includes determining a time difference between the received PRSs. |

1. A method of wireless communication by a user equipment (UE), comprising:
receiving position location reference signals (PRSs) from a plurality of remote radio heads (RRHs) and a macro eNodeB, the plurality of RRHs and the macro eNodeB having a same physical cell identity (PCI), each PRS being a same PRS and not indicating a source of transmission, a first PRS from a first RRH having been transmitted at a time that is different from each other transmission time of other PRSs from other RRHs and also different from a transmission time of a second PRS from the macro eNodeB; and determining a position location based at least in part on the first PRS and the second PRS. |
