Description

[0001] This divisional application of the invention application has an application date of May 14, 2020, an application number of 202010408881.6, and an invention title of "An Information Processing Method, Device and Terminal". Technical Field

[0002] The present invention relates to the technical field of terminals, and in particular to an information processing method, device and terminal. Background Art

[0003] The technical solutions for uplink positioning mainly include a time-delay-based UL-TDOA (Uplink Time Difference of Arrival) positioning method and an angle-based UL-AOA (Uplink Angle of Arrival) positioning method, etc. For the UL-TDOA time-delay positioning method, based on the different propagation distances of the terminal relative to each base station, the position of the terminal is estimated through the relative time difference (UL-RTOA, Uplink Relative Time of Arrival) between the arrival time of the SRS-Pos (Sounding Reference Signal for Positioning) and the reference time of the base station itself. For the UL-AOA angle positioning method, based on the position direction of the terminal relative to the base station, the position of the terminal is determined through multiple angle parameters.

[0004] Specifically, in the prior art, whether it is the time-delay-based UL-TDOA positioning method or the angle-based UL-AoA positioning method, the base station needs to receive the uplink reference signal sent by the terminal for positioning and perform accurate measurement to calculate the accurate position of the terminal. The prerequisite for the base station to accurately measure the uplink reference signal for positioning is that the terminal needs to transmit the uplink reference signal for positioning to the base station with an appropriate transmission power and a correct transmission beam direction. To achieve this purpose, the terminal needs to be provided or configured with a path loss reference signal or a spatial relationship information reference signal to set an appropriate transmission power or a correct transmission beam direction.

[0005] However, in the prior art, the path loss reference signal or the spatial relationship information reference signal is optional, that is, the terminal may not be able to obtain these reference signals, resulting in the terminal being unable to set an appropriate transmission power or a correct transmission beam direction, and further causing the base station to be unable to accurately measure, which affects the positioning accuracy.

[0006] As can be seen from the above, in the prior art, in the case of being unable to obtain the path loss reference signal or the spatial relationship information reference signal, the base station is unable to accurately measure, affecting the positioning accuracy. Summary of the Invention

[0007] The object of the present invention is to provide an information processing method, device and terminal, so as to solve the problem in the prior art that in the case where a path loss reference signal or a spatial relationship information reference signal cannot be obtained, the base station cannot perform accurate measurement, affecting the positioning accuracy.

[0068] To make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0069] In view of the problem in the existing technology that when the path loss reference signal or the spatial relationship information reference signal cannot be obtained, the base station cannot accurately measure, affecting the positioning accuracy, the present invention provides an information processing method, which is applied to a terminal, as Figure 1 shown, including:

[0070] Step 11: When the first signal is not provided or not configured, use the provided or configured second signal to perform the first operation;

[0071] Wherein, the first signal includes at least one of a first reference signal and a second reference signal;

[0073] The first operation includes at least one of calculating path loss and setting spatial relationship;

[0074] The first reference signal refers to the reference signal used as the path loss reference; the second reference signal refers to the reference signal used as the spatial relationship information; the third reference signal refers to the synchronization signal block SSB of the serving cell for obtaining the master information block MIB information.

[0075] The information processing method provided by the embodiment of the present invention performs a first operation by using a provided or configured second signal when the first signal is not provided or not configured; wherein, the first signal includes at least one of a first reference signal and a second reference signal; the second signal includes at least one of a first reference signal, a second reference signal, and a third reference signal, and the first signal is different from the second signal; the first operation includes at least one of calculating a path loss and setting a spatial relationship; the first reference signal refers to a reference signal used as a path loss reference; the second reference signal refers to a reference signal used as spatial relationship information; the third reference signal refers to a synchronization signal block SSB of a serving cell for obtaining master information block MIB information; it can be realized that when the path loss reference signal or the spatial relationship information reference signal cannot be obtained, the terminal can still transmit the uplink reference signal for positioning to the base station with an appropriate transmission power and a correct transmission beam direction, ensuring that the base station accurately performs measurements and improving the system positioning accuracy; it well solves the problem in the prior art that when the path loss reference signal or the spatial relationship information reference signal cannot be obtained, the base station cannot accurately perform measurements, affecting the positioning accuracy.

[0076] Wherein, when the first signal is the first reference signal and the second signal is the second reference signal, the first operation refers to calculating a path loss.

[0077] In the embodiment of the present invention, when the first signal is the first reference signal and the second signal is the second reference signal, the configuration information of the second reference signal notified to the terminal includes the transmission power information of the second reference signal.

[0078] Specifically, when the first signal is the first reference signal and the second signal is the second reference signal, the performing the first operation by using the provided or configured second signal includes: when the number of the second signals is at least two, using the second signal with the largest reference signal received power (RSRP) value to calculate the path loss.

[0079] In the embodiment of the present invention, when the first signal is the first reference signal, the second signal is the second reference signal, and the second signal is a sounding reference signal (SRS) sent by the terminal to the serving cell, the second signal is not used to calculate the path loss.

[0080] Wherein, when the first signal is the second reference signal and the second signal is the first reference signal, the first operation refers to setting a spatial relationship.

[0081] Specifically, when the first signal is the second reference signal and the second signal is the first reference signal, the step of using the provided or configured second signal to perform a first operation includes: when the number of the second signals is at least two, using the second signal with the largest reference signal received power (RSRP) value to set the spatial relationship.

[0082] In an embodiment of the present invention, when the second signal is the third reference signal, the step of using the provided or configured second signal to perform a first operation includes: using the reference resource obtained from the SSB to perform the first operation.

[0083] The information processing method provided in the embodiments of the present invention will be further described below.

[0084] Based on the above problems, an embodiment of the present invention provides an information processing method, which can be specifically implemented as a method for configuring fallback path loss reference information or spatial relationship reference information; mainly involving: if a terminal is not provided or configured with a first reference signal and / or a second reference signal, the terminal uses at least one of the first reference signal, the second reference signal, and the third reference signal to calculate the path loss or set the spatial relationship. Among them, the first reference signal refers to the reference signal provided or configured for the terminal to be used as the path loss reference; the second reference signal refers to the reference signal provided or configured for the terminal to be used as the spatial relationship information; the third reference signal refers to the SSB (synchronization signal block) of the serving cell of the terminal for obtaining MIB (master information block) information.

[0085] Specifically, the solution provided in the embodiment of the present invention involves the following four parts:

[0086] The first part, if the terminal is not provided or configured with the first reference signal;

[0087] (1) If the terminal is not provided or configured with the first reference signal, the terminal uses the third reference signal to calculate the path loss.

[0088] (2) If the terminal is not provided or configured with the first reference signal but is provided or configured with the second reference signal, the terminal uses the second reference signal to calculate the path loss. The configuration information of the second reference signal notified to the terminal includes the transmit power information of the second reference signal.

[0089] (3) If the terminal is configured with multiple second reference signals, use the second reference signal with the largest RSRP (reference signal received power) value to calculate the path loss.

[0090] (4) If the second reference signal of the terminal is the SRS (sounding reference signal) sent by the terminal to the serving cell, the terminal does not use the second reference signal to calculate the path loss.

[0091] Part 2, if the terminal does not provide or is not configured with the second reference signal;

[0092] (5) If the terminal is not provided or is not configured with the second reference signal, the terminal uses the third reference signal to set the spatial relationship.

[0093] (6) If the terminal is not provided or is not configured with the second reference signal but is provided or is configured with the first reference signal, the terminal uses the first reference signal to set the spatial relationship.

[0094] (7) If the terminal is configured with multiple first reference signals, the first reference signal with the largest RSRP value is used to set the spatial relationship.

[0095] Part 3, if the terminal does not provide or is not configured with the first reference signal and the second reference signal;

[0096] (8) If the terminal is not provided or is not configured with the first reference signal and the second reference signal, the terminal uses the third reference signal to calculate the path loss.

[0097] (9) If the terminal is not provided or is not configured with the first reference signal and the second reference signal, the terminal uses the third reference signal to set the spatial relationship.

[0098] (10) In all of the above solutions, when the terminal uses the third reference signal to calculate the path loss, it means that the terminal uses the RS (reference signal) resource obtained from the SSB of the serving cell used to obtain the MIB (that is, it can also be understood as using the RS resource in the SSB, and the SSB is used for the serving cell to obtain the MIB; that is, the above reference resource) to calculate the path loss.

[0099] (11) In all of the above solutions, when the terminal uses the third reference signal to set the spatial relationship, it means that the terminal uses the RS resource obtained from the SSB of the serving cell used to obtain the MIB to set the spatial relationship.

[0100] Part 4, the behavior of the terminal after calculating the path loss and setting the spatial relationship;

[0101] (12) In all of the above solutions, after the terminal uses the first reference signal, the second reference signal or the third reference signal to calculate the path loss, the terminal performs power control according to the obtained path loss and sends an uplink reference signal for positioning.

[0102] (13) In all of the above solutions, after the terminal uses the first reference signal, the second reference signal or the third reference signal to set the spatial relationship, the terminal adjusts the transmit beam direction according to the set spatial relationship and sends an uplink reference signal for positioning.

[0103] The following is an example of the solution provided by the embodiments of the present invention.

[0104] Example 1 (if the terminal does not provide or is not configured with the first reference signal):

[0105] If the terminal is not provided or is not configured with the first reference signal, the terminal uses at least one of the second reference signal and the third reference signal to calculate the path loss.

[0106] Wherein, the first reference signal refers to the reference signal provided or configured for the terminal as a path loss reference; the second reference signal refers to the reference signal provided or configured for the terminal as spatial relationship information; the third reference signal refers to the SSB of the serving cell of the terminal for obtaining MIB information.

[0107] If the terminal is not provided or is not configured with the first reference signal, the terminal uses the third reference signal to calculate the path loss.

[0108] If the terminal is not provided or is not configured with the first reference signal but is provided or configured with the second reference signal, the terminal uses the second reference signal to calculate the path loss. The configuration information of the second reference signal notified to the terminal includes the transmission power information of the second reference signal.

[0109] If the terminal is configured with multiple second reference signals, the second reference signal with the largest RSRP value is used to calculate the path loss.

[0110] If the second reference signal of the terminal is the SRS sent by the terminal to the serving cell, the terminal does not use the second reference signal to calculate the path loss.

[0111] Specifically, as Figure 2 shown, the serving cell of the terminal UE1 for obtaining MIB information is cell 1 in its serving base station gNB1. UE1 obtains the MIB information from the SSB1 information sent by cell 1 of gNB1, thereby completing system access. Before UE1 sends SRS-Pos2 to the neighboring base station gNB2, it needs to first determine the transmission power of SRS-Pos2. If UE1 is provided with a reference signal for path loss reference, then UE1 can calculate the path loss according to this path loss reference signal and perform transmission power setting. However, this path loss reference signal is an optional configuration, so it is possible that the terminal is not provided with this information, and at this time, the terminal will be unable to determine the transmission power of its SRS-Pos2, resulting in inaccurate transmission power setting and affecting the positioning accuracy. Therefore, to solve this problem, in this example, if the terminal is not provided or is not configured with the first reference signal, the terminal uses the third reference signal (i.e., Figure 2SSB1 in it, where SSB1 is the SSB sent by the serving cell used by UE1 to obtain MIB information, to calculate the path loss; or, if the terminal is configured with a second reference signal (i.e., Figure 2 DL-PRS (Downlink Positioning Reference Signal) 2 in it, where DL-PRS2 was originally used as a spatial relationship reference signal), then the terminal can also use the second reference signal to calculate the path loss.

[0112] It should be noted that, to facilitate the terminal to calculate the path loss, for the second reference signal used for the terminal's path loss calculation, when configuring, the transmit power information needs to be configured.

[0113] By adopting the method in this example, the path loss can be calculated by using the SSB of the serving cell already provided to the terminal or the spatial relationship reference information, so that when the terminal sends the uplink reference signal for positioning, the transmit power setting is more accurate, thereby improving the system positioning accuracy.

[0114] Example 2 (if the terminal does not provide or is not configured with a second reference signal):

[0115] If the terminal is not provided or not configured with a second reference signal, the terminal uses at least one of the first reference signal and the third reference signal to set the spatial relationship.

[0116] Among them, the first reference signal refers to the reference signal provided or configured for the terminal as the path loss reference; the second reference signal refers to the reference signal provided or configured for the terminal as the spatial relationship information; the third reference signal refers to the SSB of the serving cell of the terminal used to obtain MIB information.

[0117] If the terminal is not provided or not configured with a second reference signal, the terminal uses the third reference signal to set the spatial relationship.

[0118] If the terminal is not provided or not configured with a second reference signal but is provided or configured with a first reference signal, the terminal uses the first reference signal to set the spatial relationship.

[0119] If the terminal is configured with multiple first reference signals, the first reference signal with the largest RSRP value is used to set the spatial relationship.

[0120] Specifically, such as Figure 3As shown, the serving cell of the terminal UE1 for obtaining MIB information is cell 1 in its serving base station gNB1. UE1 obtains the MIB information from the SSB1 information sent by cell 1 of gNB1, thereby completing system access. Before UE1 sends SRS-Pos2 to the neighboring base station gNB2, it needs to first determine the transmission beam direction of SRS-Pos2. If UE1 is provided with a reference signal for spatial relationship information, then UE1 can determine the spatial relationship information based on this reference signal and perform transmission beam direction setting. However, this reference signal used as spatial relationship information is an optional configuration, so it is possible that the terminal is not provided with this information. In this case, the terminal will be unable to determine the transmission beam direction of its SRS-Pos2, resulting in inaccurate transmission beam direction setting and affecting the positioning accuracy. Therefore, to solve this problem, in this example, if the terminal is not provided or not configured with a second reference signal, the terminal uses a third reference signal (i.e., Figure 3 the SSB1 in, and SSB1 is the SSB sent by the serving cell of UE1 for obtaining MIB information) to set the spatial relationship; or, if the terminal is configured with a first reference signal (i.e., Figure 3 the SSB2 in, and SSB2 was originally used as a path loss reference signal), then the terminal can also use the first reference signal to set the spatial relationship.

[0121] By adopting the method in this example, the spatial relationship can be set by using the SSB of the serving cell already provided to the terminal or the path loss reference signal, so that when the terminal sends an uplink reference signal for positioning, the transmission beam direction setting is more accurate, thereby improving the system positioning accuracy.

[0122] Example 3 (if the terminal does not provide or configure the first reference signal and the second reference signal):

[0123] If the terminal is not provided or not configured with the first reference signal and the second reference signal, the terminal uses the third reference signal to calculate the path loss.

[0124] In all the above schemes, the terminal uses the third reference signal to calculate the path loss, which means that the terminal uses the RS resources obtained from the SSB of its serving cell for obtaining MIB to calculate the path loss.

[0125] Specifically, as Figure 4As shown in the figure, the serving cell of the terminal UE1 for obtaining MIB information is Cell 1 in its serving base station gNB1. UE1 obtains the MIB information from the SSB1 information sent by Cell 1 of gNB1, thereby completing system access. Before UE1 sends SRS-Pos2 to the neighboring base station gNB2, it needs to first determine the transmission power of SRS-Pos2. If UE1 is neither provided with the first reference signal nor the second reference signal, at this time, the terminal will be unable to determine the transmission power of its SRS-Pos2, resulting in inaccurate transmission power setting and affecting the positioning accuracy. Therefore, to solve this problem, in this example, if the terminal is not provided with or not configured with the first reference signal and the second reference signal, the terminal uses the third reference signal (i.e., Figure 4 the SSB1 in

[0126] ), and SSB1 is the SSB sent by the serving cell of UE1 for obtaining MIB information) to calculate the path loss.

[0127] Example 4 (if the terminal is not provided with or not configured with the first reference signal and the second reference signal):

[0128] If the terminal is not provided with or not configured with the first reference signal and the second reference signal, the terminal uses the third reference signal to set the spatial relationship.

[0129] In all the above solutions, the terminal uses the third reference signal to set the spatial relationship, which means that the terminal uses the RS resources obtained from the SSB of its serving cell for obtaining MIB to set the spatial relationship.

[0130] Specifically, as Figure 5 shown, the serving cell of the terminal UE1 for obtaining MIB information is Cell 1 in its serving base station gNB1. UE1 obtains the MIB information from the SSB1 information sent by Cell 1 of gNB1, thereby completing system access. Before UE1 sends SRS-Pos2 to the neighboring base station gNB2, it needs to first determine the transmission beam direction of SRS-Pos2. If UE1 is neither provided with the first reference signal nor the second reference signal, at this time, the terminal will be unable to determine the transmission beam direction of its SRS-Pos2, resulting in inaccurate transmission beam direction setting and affecting the positioning accuracy. Therefore, to solve this problem, in this example, if the terminal is not provided with or not configured with the first reference signal and the second reference signal, the terminal uses the third reference signal (i.e., Figure 5Set the spatial relationship using SSB1 in []. SSB1 is the SSB sent by the serving cell of UE1 for obtaining MIB information.

[0131] By using the method in this example, the spatial relationship can be set by using the SSB of the serving cell of the terminal that the terminal has already obtained, so that when the terminal sends an uplink reference signal for positioning, the transmission beam direction is set more accurately, thereby improving the system positioning accuracy.

[0132] Example 5 (Behavior of the terminal after calculating the path loss):

[0133] In all the above schemes, after the terminal calculates the path loss using the first reference signal, the second reference signal, or the third reference signal, the terminal performs power control according to the obtained path loss and sends an uplink reference signal for positioning.

[0134] Specifically, as Figure 6 shown, before the terminal transmits an uplink reference signal for positioning, it performs open-loop or closed-loop power control according to the path loss obtained from SSB1 or from DL-PRS2. The way to obtain the path loss is to receive the RSRP of SSB1 or DL-PRS2 and combine it with the transmission power of SSB1 or DL-PRS2, so that the path loss between UE1 and gNB2 can be calculated. Then, according to the path loss, a power setting method with partial path loss compensation is used to calculate the transmission power of SRS-Pos2 sent to gNB2. During the path loss calculation process, it is assumed that the channel has uplink-downlink channel reciprocity, that is: UE1 can infer the uplink channel path loss according to the downlink channel path loss. Of course, if the path loss reference signal itself is an uplink reference signal, there is no need to assume that the channel has uplink-downlink channel reciprocity.

[0135] By using the method in this example, the path loss can be calculated by using the SSB or spatial relationship reference information of the serving cell that has been provided to the terminal, so that when the terminal sends an uplink reference signal for positioning, the transmission power is set more accurately, thereby improving the system positioning accuracy.

[0136] Example 6 (Behavior of the terminal after setting the spatial relationship):

[0137] In all the above schemes, after the terminal sets the spatial relationship using the first reference signal, the second reference signal, or the third reference signal, the terminal adjusts the transmission beam direction according to the set spatial relationship and sends an uplink reference signal for positioning.

[0138] Specifically, as Figure 7As shown in the figure, before the terminal transmits the uplink reference signal for positioning, it will set the transmission beam direction according to the spatial relationship information obtained from SSB1 or SSB2. The way to obtain the spatial relationship information is through the reception beam direction of SSB1 or SSB2, so that the transmission beam direction between UE1 and gNB2 can be obtained. Then, according to this transmission beam direction, the transmission beam direction of SRS-Pos2 sent to gNB2 is determined. During the process of determining the transmission beam direction, it is assumed that the channel has transmit-receive direction reciprocity, that is, UE1 can deduce the transmission beam direction according to the reception beam direction. Of course, if the spatial relationship information reference signal itself is an uplink reference signal, there is no need to assume that the channel has transmit-receive direction reciprocity.

[0139] By using the method in this example, the spatial relationship can be set by using the SSB or path loss reference signal of the serving cell already provided to the terminal, so that when the terminal transmits the uplink reference signal for positioning, the transmission beam direction setting is more accurate, thereby improving the system positioning accuracy.

[0140] It is hereby stated that in the drawings of the embodiments of the present invention, LMF involved represents a positioning management function unit.

[0141] As can be seen from the above, the embodiments of the present invention provide a configuration method for fallback path loss reference information or spatial relationship reference information. Compared with the prior art, by using the configuration method for fallback path loss reference information or spatial relationship reference information proposed by the present invention, the path loss calculation or spatial relationship setting can be carried out by using the spatial relationship reference information or path loss reference information already provided to the terminal, so that when the terminal transmits the uplink reference signal for positioning, the transmission power setting or transmission beam direction setting is more accurate, thereby improving the system positioning accuracy.

The module can also be implemented using programmable hardware devices, such as field programmable gate arrays, programmable array logic, programmable logic devices, etc.

[0178] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
