Abstract
A method of wireless communication includes generating a unique position reference signal (PRS) for a remote radio head having a same physical cell identity (PCI) as a macro eNodeB. The unique PRS is based on a virtual cell ID and/or unique cell global identification (CGI) of the remote radio head such that the unique PRS is different from a PRS of the macro eNodeB. The PRS of the macro eNodeB is based on the PCI. The method also includes transmitting the unique PRS.
Claims16
A method of wireless communication, comprising:
- generating a unique position reference signal (PRS) for a remote radio head having a same physical cell identity (PCI) as a macro eNodeB, the unique PRS being based on at least one of a virtual cell ID and cell global identification (CGI) of the remote radio head such that the unique PRS is different from a PRS of the macro eNodeB, the PRS of the macro eNodeB being based on the PCI;
- and
- transmitting the unique PRS to a user equipment located in a region of a cell of the RRH that overlaps with a cell of the macro eNodeB.
An apparatus for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor being configured:
- to generate a unique position reference signal (PRS) for a remote radio head (RRH) having a same physical cell identity (PCI) as a macro eNodeB, the unique PRS being based on at least one of a virtual cell ID and cell global identification (CGI) of the remote radio head such that the unique PRS is different from a PRS of the macro eNodeB, the PRS of the macro eNodeB being based on the PCI;
- and
- to transmit the unique PRS to a user equipment located in a region of a cell of the RRH that overlaps with a cell of the macro eNodeB.
A non-transitory computer-readable medium having non-transitory program code recorded thereon for wireless communication in a wireless network, the program code being executed by at least one processor and comprising:
- program code to generate a unique position reference signal (PRS) for a remote radio head (RRH) having a same physical cell identity (PCI) as a macro eNodeB, the unique PRS being based on at least one of a virtual cell ID and cell global identification (CGI) of the remote radio head such that the unique PRS is different from a PRS of the macro eNodeB, the PRS of the macro eNodeB being based on the PCI;
- and
- program code to transmit the unique PRS to a user equipment located in a region of a cell of the RRH that overlaps with a cell of the macro eNodeB.
An apparatus for wireless communication, comprising:
- means for generating a unique position reference signal (PRS) for a remote radio head (RRH) having a same physical cell identity (PCI) as a macro eNodeB, the unique PRS being based on at least one of a virtual cell ID and cell global identification (CGI) of the remote radio head such that the unique PRS is different from a PRS of the macro eNodeB, the PRS of the macro eNodeB being based on the PCI;
- and
- means for transmitting the unique PRS to a user equipment located in a region of a cell of the RRH that overlaps with a cell of the macro eNodeB.
