Problems solved by technology

Although this method can effectively suppress the interference of the serving cell signal to the adjacent cell signal and improve the positioning accuracy, the downlink data reception response (ACK or NAK) transmission cannot be performed in this subframe, which will seriously affect the mixed Timing synchronization for automatic repeat request (HARQ)

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The core idea of ​​the method provided by the present invention is: use the time-frequency resources corresponding to the preset frequency bands occupied by all Orthogonal Frequency Division Multiplexing (OFDM) symbols in a downlink subframe in a superframe as the LBS domain; or, use The time-frequency resources occupied by some OFDM symbols of at least two downlink subframes in the superframe are used as the LBS domain; the serving base station sends the indication information containing the superframe information of the LBS domain to the MS; each neighboring cell base station sends Reference signal to the MS.

[0025] Wherein, in the LBS domain, reference signals for each neighboring cell may adopt one of Time Division Multiplexing (TDM) ...

Abstract

The invention provides a method for transmitting and receiving positioning reference signals. A service base station transmits indication information of super-frame information containing the position where a location-based service (LBS) domain is located to a moving station (MS); all adjacent neighborhood base stations transmit reference signals used for MS positioning measurement to the MS on the LBS domain; and the LBS domain occupies time-frequency resources occupied by partial orthogonal frequency division multiplexing (OFDM) symbols in sub frames. The method can ensure positioning measurement accuracy and simultaneously meets requirements of a hybrid automatic repeat request (HARQ) for timing synchronization.

Description

[0001] This application is a divisional application with the application number "200910206451.X". The filing date of the original application is November 13, 2009, and the title of the invention is "A method for transmitting and receiving positioning reference signals. technical field [0002] The invention relates to the technical field of mobile communication, in particular to a method for transmitting and receiving positioning reference signals. Background technique [0003] The research on wireless positioning technology has been widely used in fields such as the initial automatic vehicle positioning system and subsequent public transportation, taxi dispatching, and public security tracking. With the increasing demand for location-based information services, wireless positioning technology has gradually become the focus of research. [0004] In the existing commonly used cellular mobile communication networks, the most commonly used wireless positioning method is the tim...
