Description

Method and device for positioning in UE, base station and service center

Technical Field

The present invention relates to positioning schemes in wireless communication systems, and more particularly, to methods and apparatus for multipoint positioning.

Background

The application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. The emergence of a number of emerging application scenarios and application services (such as internet of things and internet of vehicles) places increasingly higher demands on the functionality and accuracy of positioning. In the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 times of the whole meeting, it is decided to perform research on a New air interface technology (NR, New Radio), and related positioning research is also included.

A positioning method based on OTDOA (Observed Time Difference Of Arrival), due to its advantages Of high positioning accuracy and indoor positioning, is widely adopted in existing wireless communication systems (e.g. LTE, Long Term Evolution). The basic principle of OTDOA is based on three-point positioning, and a positioning service center in a core network calculates the location coordinates of a user equipment according to the transmission delay reported by the user equipment and between three base stations in different geographical locations. The accuracy of OTDOA-based positioning is not substantially affected by the cell radius, as compared to single base station (or cell) -based positioning. In order to enable the ue to accurately measure the transmission delay with multiple base stations, the base stations are generally required to transmit Reference signals to ensure the Positioning accuracy, such as PRS (Positioning Reference Signal) in the LTE system.

Disclosure of Invention

In future wireless communication systems (such as NR), Massive MIMO (Massive MIMO) becomes an important technology for improving communication performance. In massive MIMO, multiple antennas form a narrow beam pointing in a specific direction by beamforming to improve communication quality. The beam formed by multi-antenna beamforming is generally narrow, and both communication parties need to obtain partial channel information of the other party to enable the formed beam to point to the correct direction. Before both communication parties obtain partial channel information of the other party, or when the previously obtained partial channel information has failed, the transmitting end and the receiving end need to use a larger redundancy to ensure correct reception of the transmitted signal, for example, a Beam Sweeping (Beam Sweeping) scheme, in which the transmitting end transmits the same signal multiple times in a TDM (time division Multiplexing) manner, and transmits beams for different directions each time, and the receiving end uses a different receiving Beam to select an appropriate signal from the repeated signals. Since massive MIMO is generally deployed indoors, and since each beam is narrow and directivity naturally occurs, this provides advantages for enhancing the positioning accuracy. The impact and benefits of massive MIMO are not considered in existing positioning designs (e.g., OTDOA positioning for LTE). For example, transmissions in existing PRSs are all based on conventional antenna transmission techniques (such as single antenna or transmit diversity). On the other hand, in order to meet the requirement of coverage, in a future wireless communication system, a reference signal for positioning may also need to support beam sweeping, and since transmission delays between different beams may have relatively large differences, if the existing positioning method is continuously adopted, the positioning accuracy may be deteriorated.

The invention provides a solution to the impact of the introduction of massive MIMO on the existing OTDOA-based positioning performance and the possibility to improve the positioning method. By adopting the solution of the invention, the positioning server can more accurately obtain the transmission delay information and the corresponding direction and angle information by supporting the beam sweeping and the report of the UE to the beam information, thereby ensuring and greatly improving the positioning precision. It should be noted that, without conflict, the embodiments and features in the embodiments in the UE (User Equipment) of the present application may be applied to the base station or the location service center, and vice versa.
