Abstract
Embodiments herein relate to method for transmitting positioning reference signals (PRSs) in a cell served by a base station. The base station maps PRSs onto different groups of time-frequency resources according to different respective PRS patterns, wherein each of the different groups spans one or more consecutive subframes in time. The base station transmits the PRSs in the cell in accordance with said mapping.

A method, performed by a base station, for transmitting positioning reference signals (PRSs) in a cell served by the base station, the method comprising:
- mapping PRSs onto different groups of time-frequency resources according to different respective PRS patterns, wherein each of the different groups of time-frequency resources spans one or more consecutive subframes in time;
- and
- transmitting the PRSs in the cell in accordance with the mapping.
A method, performed by a wireless device, for receiving positioning reference signals (PRSs) in a cell served by a base station, the method comprising:
- receiving, from the base station and at the wireless device in the cell, PRSs that are mapped onto different groups of time-frequency resources according to different respective PRS patterns, wherein each of the different groups of time-frequency resources spans one or more consecutive subframes in time;
- and
- measuring the PRS of at least one group for determining a location of the wireless device.
A base station serving a cell, the base station comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the base station is operative to:
- map Positioning Reference Signals (PRSs) onto different groups of time-frequency resources according to different respective PRS patterns, wherein each of the different groups spans one or more consecutive subframes in time;
- and
- transmit the PRSs in the cell in accordance with the mapping.
A wireless device configured to operate in a cell served by a base station, the wireless device comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the wireless device is operative to:
- receive Positioning Reference Signals (PRSs) from the base station at the wireless device in the cell, wherein individual ones of the PRSs are mapped onto different groups of time-frequency resources according to different respective PRS patterns, wherein each of the different groups spans one or more consecutive subframes in time;
- and
- measure the PRSs of at least one of the groups in order to enable determination of a location of the wireless device.
