Moreover, the configuration information corresponding to these new services (such as positioning services, etc.) is newly expanded information, and the UE supported by the R8 protocol cannot recognize these new information. Therefore, when sending the positioning subframe configuration to the positioning UE Also need to consider the issue of backward compatibility when information

Embodiment Construction

[0024] In order to make the above objects, features and advantages of the present invention more comprehensible, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The signal used for the positioning function can be carried by the MBSFN subframe. For the user terminal complying with the LTE R8 protocol, it can generally receive the unicast control signaling on the first 1-2 OFDM symbols in the MBSFN subframe without Any signal sent on subsequent OFDM symbols is processed. Therefore, the base station can use OFDM symbols other than 1-2 OFDM symbols to send positioning reference signals in the MBSFN subframe. When MBSFN subframes are used to carry positioning signals, please refer to figure 1 , which is a schematic flowchart of a method for sending positioning configuration information according to an embodiment of the present invention, and the method includes the following steps.

Abstract

The embodiment of the invention discloses a method and a device for transmitting positioning configuration information. The method comprises the following steps of: processing multicast broadcast single frequency network (MBSFN) subframe configuration information, so that the MBSFN subframe configuration information comprises an MBSFN subframe for positioning; establishing indicating information for indicating the MBSFN subframe for positioning in the MBSFN subframe configuration information; and transmitting the MBSFN subframe configuration information and the indicating information to positioning user equipment (UE). According to the embodiment of the invention, the positioning configuration information can be transmitted on the premise of ensuring backward compatibility.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for sending positioning configuration information. Background technique [0002] With the development of the mobile communication system, the quality of service that the system can provide is getting higher and higher. In order to maintain the long-term competitive advantage of the 3GPP (3rd Generation Partnership Project, third generation partnership project), the standard formulation work of LTE (Long Term Evolution, long term evolution system) is in progress. [0003] After the 3GPP LTE R8 version, many functions supporting new services have been introduced. For example, the 3GPP LTE R9 version has introduced the function of supporting positioning services. The positioning service is to use certain positioning methods to locate the position of UE (User Equipment, terminal or user equipment). The OTDOA (Observed Time Difference of Arri...
