Positioning method and apparatus

A positioning method, comprising:

• receiving an Observed Time Difference of Arrival (OTDOA) information request transmitted by a location server;
• transmitting an OTDOA information response carrying positioning assistance data to the location server, wherein the positioning assistance data comprises an indoor/outdoor Positioning Reference Signal (ioPRS) configuration data for each base station cell, the ioPRS is for indoor/outdoor positioning;
• wherein the ioPRS comprises:
• a first Positioning Reference Signal (PRS) and a second PRS;
• wherein Energy Per Resource Element (EPRE) of the first PRS is greater than EPRE of the second PRS;
• wherein a transmission bandwidth and positions of the second PRS are the same as a transmission bandwidth and positions of the first PRS;
• or the second PRS occupies an entire carrier bandwidth;
• wherein a time-domain configuration of the second PRS is transmitted on Orthogonal Frequency Division Multiplexing (OFDM) symbols distinct from OFDM symbols used for transmitting the first PRS.

A positioning method, comprising:

• reporting a positioning capability supported by a User Equipment (UE) to a network side, wherein the positioning capability is used by the network side to determine that the UE is capable of obtaining positioning measurements by detecting an indoor/outdoor Positioning Reference Signal (ioPRS) for indoor/outdoor positioning;
• obtaining positioning assistance data comprising ioPRS configuration data for each base station cell;
• measuring downlink signals comprising the ioPRS based on the ioPRS configuration data to obtain positioning measurements, and reporting the positioning measurements to the network side;
• wherein the ioPRS comprises:
• a first Positioning Reference Signal (PRS) and a second PRS;
• wherein Energy Per Resource Element (EPRE) of the first PRS is greater than EPRE of the second PRS;
• wherein a transmission bandwidth and positions of the second PRS are the same as a transmission bandwidth and positions of the first PRS;
• or the second PRS occupies an entire carrier bandwidth;
• wherein a time-domain configuration of the second PRS is transmitted on Orthogonal Frequency Division Multiplexing (OFDM) symbols distinct from OFDM symbols used for transmitting the first PRS.
