Description

Method for configuring uplink reference signal, base station, positioning server and system

The present invention relates to the field of communications technologies, and in particular, to a method, a base station, a positioning server, and a system for configuring an uplink reference signal. Background technique

At present, with the continuous development of mobile communication technologies, users' demand for location services is also increasing. The application scenarios of location services are diversified, such as emergency location, crime location tracking, navigation and traffic control. However, regardless of the variety of application scenarios, the industry's need for positioning is always more reliable, accurate, effective, and fast. In other words, high-precision and easy-to-implement positioning technology has always been a hot spot.

The positioning algorithm of the user equipment (User Equipment, UE) generally includes: Network-assisted Global Navigation Satellite System (GNSS) positioning, Observed Time Difference of Arrival (OTDOA) positioning , Cell Identification (CID) positioning, Uplink Time Difference of Arrival (UTDOA) positioning, and RF Pattern Matching (RFPM) positioning. Most positioning methods are implemented by detecting characteristic parameters of the radio wave signal between the UE and the base station (signal arrival time difference, signal arrival direction angle, etc.). For example, the 0TD0A positioning technology uses the UE to receive downlink reference signals respectively sent by multiple base stations, performs timing measurement on receiving downlink reference signals of different base stations, and sends a time difference of arrival of downlink reference signals between base stations to the positioning server, and the positioning server according to The arrival time difference sent by the UE is calculated to obtain the location information of the UE. For example, the UTDO A positioning technology uses a plurality of base stations or a location measurement unit (Location Measurement Unit) to receive the time when the same UE transmits the uplink reference signal. The value of the arrival time difference of the uplink reference signal is calculated, and then the positioning server calculates the location information of the UE according to the arrival time difference.

In the above positioning technology, for the UTD0A technology, the positioning accuracy is affected by the uplink reference signal. The quality of the reception is greatly affected. If the quality of the uplink reference signal received by the base station (or LMU) is poor, such as when the signal is noisy (S i gna 1 No ise Ra ti 0 ) or the signal is dry noise H ( S i When the gna 1 Interference No i se Rat io, when the cartridge is called SINR is low, the measurement of the arrival time of the uplink reference signal will cause a large error, thereby causing an error in the calculated arrival time difference, thereby causing the positioning accuracy of the UTD0A technology to be lowered. .

Example ten As a further refinement and extension of the foregoing embodiments, the embodiment further provides a method for configuring an uplink reference signal. As shown in FIG. 10, the method includes:

1 001. The base station receives configuration information sent by the positioning server.

1002. The base station refers to the configuration information sent by the positioning server to determine a configuration parameter of the uplink reference signal.

Steps 1001 and 1002 in this embodiment are the same as steps 101 and 102 in the first embodiment, and are not described here.

1003. The base station configures, according to the configuration parameter, an uplink reference signal sending manner of the UE.

Embodiment 11

As a further extension of the foregoing embodiments, the positioning server may also send the uplink reference signal configuration parameter of the neighboring cell to the base station, so that the base station configures the uplink reference signal for the UE of the local cell, thereby implementing the uplink reference configuration between the multiple cells.

Specifically, the base station receives the uplink reference signal configuration parameter of the neighboring base station that is sent by the positioning server on the LPPa signaling, and determines the uplink reference signal configuration parameter of the UE of the local cell according to the uplink reference signal configuration parameter of the neighboring base station, and according to the determined The configuration parameter configures the uplink reference signal transmission mode of the UE.

In another implementation manner of the embodiment, the base station may further receive an uplink reference signal configuration parameter of the neighboring base station sent by the positioning server after sending the configuration parameter to the positioning server, and configure parameters according to the uplink reference signal of the neighboring base station. The determined configuration parameters are corrected, and then the uplink reference signal transmission mode of the UE is reconfigured according to the modified configuration parameters.

Further, the positioning server may further send the uplink reference signal configuration parameter of the base station to the phase a neighboring base station, so that the neighboring base station does not perform the configuration of the uplink reference signal transmission mode for the UE that is accessed by the neighboring base station according to the configuration parameter of the uplink reference signal, or avoids configuring the base station when the uplink reference signal transmission mode is configured for the UE that is accessed by the neighboring base station.

Example twelve

As a further extension of the foregoing embodiments, or the replacement of the eleventh embodiment, the positioning server may further calculate and send an uplink reference signal sending rule to the base station, where the rule includes a signal sending rule of multiple cells, and the base station receives the uplink. After the reference signal transmission rule is used, the configuration parameters of the UE of the current cell are determined or corrected according to the rule, thereby implementing an interference coordination scheme for configuring an uplink reference signal between multiple cells.

The uplink reference signal sending rule may be a time division rule, a frequency division rule or a space division rule, or a combination of at least two rules. The time division rule specifies, at what time, the UEs of the base stations send the uplink reference signals, and the UEs of the base stations send the uplink reference signals at other times; the frequency division rule specifies which base station UEs send the uplink reference on the frequency domain resources. Signal, which base station UEs send uplink reference signals and the like on other frequency domain resources. The positioning server performs overall planning on the time domain and frequency domain of each small area at the upper layer, and then sends the established rules to the base stations of each cell to ensure that the interference of the different cell UEs in the time domain, the frequency domain or the air domain.

Taking the time division rule as an example, the positioning server sends a bit string to a base station to distinguish different periods of the uplink reference signal and the subframe offset position. For other base stations, the positioning server allocates appropriate uplink reference signal time domain configurations to the base stations according to their own algorithms, so as to stagger the transmission of mutually interfered uplink reference signals in the same time domain.

Taking the frequency division rule as an example, the positioning server sends a bit string to a base station to distinguish different frequency domain positions of the uplink reference signal. For other base stations, the positioning server allocates appropriate uplink reference signal frequency domain configurations to the base stations according to their own algorithms, so as to stagger the mutually interfered uplink reference signals. Sending on the same frequency domain resource.

In this embodiment, the uplink reference signal transmission rule is sent in the form of leg t ing information or pat tern information, and the specific form in the actual application is not limited thereto.

In this embodiment, the manner in which the positioning server sends the uplink reference signal transmission rule can be divided into two cases:

1) The positioning server directly sends the uplink reference signal transmission rule to the base station, and the base station determines the configuration parameter of the uplink reference signal of the UE according to the uplink reference signal transmission rule, and configures the UE of the local cell;

2) After the base station sends the determined configuration parameter to the positioning server, the positioning server sends an uplink reference signal sending rule to the base station, and the base station corrects the determined configuration parameter according to the uplink reference signal sending rule, and then according to the modified configuration. The parameters are reconfigured for the UE in the cell.

Further, the positioning server may further send the sending rule that the base station sends the uplink reference signal to the neighboring base station, so that the neighboring base station configures the uplink reference signal for the UE that is accessed by the neighboring base station according to the sending rule, so as to avoid the configuration being the same as the base station or Similar uplink reference signal configuration parameters, thereby achieving interference coordination between the various base stations.
