Technical Field

Background
Currently, an NR (New Radio, new air interface) terminal searches for a PRS (Positioning Reference signal) signal according to PRS resource information provided by a cellular network, so as to support high-precision Positioning based on the cellular network. However, if the PRS resources configured to the NR terminal by the cellular network once are too many, the efficiency of the terminal to measure and search for valid PRS signals is greatly reduced, and the positioning delay of the terminal is also increased.
In some scenarios, for example, when the terminal is in a connected state, the network may effectively configure the PRS signal in real time according to a serving base station where the terminal is located, but in other scenarios, the network may not configure the PRS for the terminal in real time, and PRS resources need to be preconfigured. For example, when the terminal wakes up in an inactive state (i.e., a non-connected state), PRS (PRS) needs to be measured to start positioning, a pre-configured PRS resource is needed to reduce the delay of real-time positioning service.
However, in the scenario of pre-configuring the PRS resources, it is difficult for the current resource configuration method to reasonably configure the PRS resources, which causes excessive consumption of air interface resources and low positioning efficiency.

Each cell broadcasts only one SIAID, used in conjunction with the PLMN ID. The SIAID indicates to which system message cell the cell belongs. If the SIB message is of area-specific level, the SIAID can know the system message cell to which the SIB message belongs.
As shown in fig. 2, an embodiment of the present invention provides a resource allocation method, including:
In this step, the terminal may obtain the first resource by obtaining resource configuration information of the first resource, where the first resource is used for searching for a signal (e.g., positioning reference signal PRS). For example, the UE may acquire the resource configuration information through an LPP (LTE Positioning Protocol) Protocol. Wherein, the resource configuration information may be pre-configured.
In the embodiment of the invention, the terminal can acquire whether the first resource is effective or not through the resource configuration information, and further can determine whether to search the signal on the first resource or not according to the effectiveness of the first resource, so that the time and the required power consumption of the terminal for searching the signal on the ineffective first resource can be reduced, the efficiency of the terminal is improved, and the consumption of air interface resources is reduced.
As an optional embodiment, the determining, by the terminal, the validity of the first resource according to the area identifier to which the first resource belongs includes:
the terminal compares the area identification to which the first resource belongs with the area identification corresponding to the cell in which the terminal is currently located;
and determining that the first resource is valid under the condition that the area identifier to which the first resource belongs is the same as the area identifier corresponding to the cell in which the terminal is currently located.
In this embodiment, the region identifier may be SIAID, TAC, RNA ID, or read. The terminal can know whether the first resource is effective for the terminal by comparing whether the area identifier to which the first resource belongs and the area identifier corresponding to the cell in which the terminal currently belongs (namely the area identifier to which the terminal currently belongs) are consistent, so that the terminal can determine whether to perform signal search on the first resource according to the effectiveness of the first resource, thereby reducing the time for the terminal to search for signals on the ineffective first resource, avoiding unnecessary power consumption, reducing time delay and improving efficiency.
As another optional embodiment, the determining, by the terminal, the validity of the first resource according to the valid time length of the first resource includes:
determining whether the time length of the terminal for storing the resource configuration information is less than or equal to the effective time length or not according to the effective time length of the first resource;
and determining that the first resource is valid when the time length of the terminal for storing the resource configuration information is less than or equal to the valid time length.
It should be noted that the valid time length of the first resource may indicate how long the first resource may be valid, and after the terminal acquires the resource configuration information, the terminal may store the resource configuration information, and when the terminal is ready to search for a signal on the first resource, the terminal may compare the time length that the resource configuration information has been stored on the terminal with the valid time length of the first resource, so as to determine the validity of the first resource according to the size relationship between the time length and the valid time length.
In the implementation, the terminal can know whether the first resource is valid for the terminal currently through the valid time length of the first resource, so that the terminal can determine whether to search for the signal on the first resource according to the validity of the first resource, thereby reducing the time for the terminal to search for the signal on the invalid first resource, avoiding unnecessary power consumption, reducing time delay and improving efficiency.
As another optional embodiment, the determining, by the terminal, the validity of the first resource according to the area identifier to which the first resource belongs and the valid time length of the first resource includes:
and determining that the first resource is valid when the area identifier to which the first resource belongs is the same as the area identifier corresponding to the cell in which the terminal is currently located, and the time length of the terminal for storing the resource configuration information is less than or equal to the valid time length.
It should be noted that, after determining the validity of the first resource, the terminal may perform signal search in the following manner:
in a first mode, if a first resource is valid, signal search is performed on the first resource; if the first resource is not valid, the search for signals on the first resource is abandoned.
In this way, the terminal can quickly increase the speed and efficiency of searching for signals on the valid first resource, while the terminal can further increase the speed and efficiency of searching for valid signals by abandoning the search for signals on the invalid first resource.
In the second method, when signal search is started, signal search is preferentially performed on the valid first resource, and when the signal (e.g., PRS signal) measured by the terminal is insufficient, signal search is attempted again on the invalid first resource.
As an alternative embodiment, the method further comprises:
determining the priority of the first resource according to the effectiveness of the first resource;
performing a signal search on the first resource whose priority is high.
In the implementation, the terminal can judge whether the first resource is valid or not by combining the area identifier to which the first resource belongs and the valid time length of the first resource, so that the terminal can determine whether to search for the signal on the first resource or not according to the validity of the first resource, thereby reducing the time for the terminal to search for the signal on the invalid first resource, avoiding unnecessary power consumption, reducing time delay and improving efficiency.
It can be understood that, for the first resource with low priority, the signal search on the first resource can be directly abandoned, or the signal search on the first resource with low priority can be attempted when the signal (e.g. PRS signal) measured by the terminal is not enough.
As an alternative embodiment, after the signal search is performed on the first resource with the high priority, the method further includes:
performing a signal search on the first resource whose priority is low.
In this embodiment, when the signals (e.g., PRS signals) measured by the terminal are not sufficient, a signal search may be attempted on an invalid first resource.
As an optional embodiment, the determining the priority of the first resource according to the validity of the first resource includes at least one of:
determining that the priority of the first resource is high if the first resource is valid;
determining that the priority of the first resource is low if the first resource is invalid.
In this way, the terminal can perform signal search on the valid first resource (i.e., the first resource with higher priority) by priority search.
As an optional embodiment, the area identification comprises at least one of:
a system message cell identity, SIAID;
tracking area code TAC;
an access network notification area identification (RNA ID);
the resource allocation valid area read.
The following specifically exemplifies the scheme provided in the embodiments of the present application.
In a first embodiment, a terminal determines validity of a first resource according to an area identifier to which the first resource belongs:
step 1: when the terminal prepares to use the resource configuration information of the first resource, comparing the SIAID (or TAC, or RNA ID, or read) in the SIB1 message acquired by the current serving cell with the area identifier (that is, area ID, which may be the SIAID, or TAC, or RNA ID, or read) to which the first resource belongs in the resource configuration information;
if the first resource and the second resource are consistent, determining that the first resource is in the effective area, namely determining that the first resource is effective; if the first resource is determined not to be in the valid area, that is, the first resource is determined to be invalid, the terminal may decrease the search priority of the first resource (that is, the priority of the first resource), so that the terminal may preferentially search for a signal on the valid first resource, that is, preferentially search for a signal in the valid area.
Step 2: when starting to search for a Signal (e.g., a positioning Signal) indicated by the resource configuration information, signals within the active area, such as SSB (Synchronization Signal and PBCH block) and PRS signals, are preferentially searched. Therefore, the signal is searched in the effective area, and the speed and the efficiency of searching the signal by the UE can be quickly improved.
And step 3: when the signals (e.g., PRS) measured by the UE are not sufficient, a search for signals that are not within the range of the valid area is re-attempted, i.e., a search for signals on the invalid first resource is attempted.
It can be understood that, after determining that the first resource is invalid, the terminal may also abandon the search for the signal that is not in the valid area, for example, no longer search for the signal corresponding to the first resource, which can further improve the speed and efficiency of the UE searching for the valid signal.
In a second embodiment, the terminal determines the validity of the first resource according to the valid time length of the first resource:
step 1: and after the terminal acquires the resource configuration information of the first resource, the resource configuration information can be stored.
And 2, step: when the terminal is ready to use the resource configuration information, the duration (i.e., time length) stored in the terminal according to the resource configuration information may be compared with the effective time length of the first resource.
If the time does not exceed the time limit, that is, the time length of the terminal for storing the resource configuration information is less than or equal to the valid time length, it is determined that the first resource is still within the valid time limit, that is, it is determined that the first resource is valid, and the UE may consider searching for a signal on the first resource, for example, searching for a signal corresponding to the first resource; if the time length of the terminal for storing the resource configuration information exceeds the valid time length (i.e., the valid duration), it is determined that the first resource is invalid, and at this time, the terminal may decrease the search priority of the first resource. Therefore, the terminal can preferentially search for signals (such as SSB and PRS) corresponding to the effective first resource, and the signal searching speed and efficiency of the UE can be rapidly improved.
And step 3: when the signal indicated by the resource configuration information is searched, the signals (such as the SSB and PRS) corresponding to the valid first resource are preferentially searched.
And 4, step 4: when the signals (e.g., PRS) measured by the UE are not sufficient, a search is re-attempted for signals corresponding to the first resources that are no longer valid.
It can be understood that, after determining that the first resource is invalid, the terminal may also abandon searching for the signal on the first resource, for example, no longer search for a signal corresponding to the first resource, which can further improve the speed and efficiency of searching for a valid signal by the UE.
In summary, in the embodiment of the present invention, the terminal may obtain whether the first resource is valid through the resource configuration information, and then determine whether to perform signal search on the first resource according to the validity of the first resource, so that time and required power consumption for the terminal to search for a signal on the invalid first resource may be reduced, efficiency of the terminal is improved, and consumption of an air interface resource is reduced.
As shown in fig. 3, an embodiment of the present invention further provides a resource allocation method, including:
In this step, the network device (e.g. the location server) may put the area identifier to which the first resource belongs in the resource configuration information content pre-configured by the LPP, and send the area identifier to the terminal through the LPP protocol.
Specifically, the positioning server may configure the resource configuration information (such as PRS resources) to the terminal in advance on the LPP interface, and notify the terminal of the downlink first resource. The resource configuration information may include resource configuration information such as a time domain, a frequency domain, and a space domain of an existing resource, and may also indicate an area identifier to which the resource configuration information belongs (for example, indicate an area identifier to which the first resource belongs). In this way, the region validity of the first resource is distinguished by dividing different first resources into different region identifications. The area identifier may be a SIAID, a TAC, an RNA ID, or a read of a cell to which the first resource belongs.
In the embodiment of the invention, the network equipment can reasonably pre-configure the signal for the terminal through the configuration of the resource configuration information, so that the terminal can know whether the first resource is effective through the resource configuration information, and further can determine whether to search the signal on the first resource according to the effectiveness of the first resource, thereby reducing the time and the required power consumption of the terminal for searching the signal on the ineffective first resource, improving the efficiency of the terminal and reducing the consumption of air interface resources.
It should be noted that, in the prior art, a cell ID list of an effective area is usually configured directly in a resource (e.g., a PRS resource), and this method needs to consume too many air interface resources. For example, following the neighbor cell list concept defined in SIB3 (System Information Block Type3, serving cell reselection Information), 16 valid cell IDs are configured for each resource, that is, the configured resource is valid in all 16 cells. The maximum value of physcelld (also called PCI) in the protocol is 1008, and if 16 × 16bit =160bit is consumed by configuring one resource by using the conventional configuration method, 256 air interface resources are 256 × 16 × 10bit =40mbit by configuring 256 resources. Therefore, the air interface resource consumption brought by the pure cell list configuration method is larger. When the resource allocation method of the embodiment of the invention is adopted, an air interface resource which consumes 24 bits at most (for example, when the area identifier is the SIAID, the length of the SIAID is 24 bits) is allocated. That is to say, in the case that 256 resources need to be configured, the resource configuration method according to the embodiment of the present invention may save 256 × 160-24) =34816 bits, which is about 34Mbit, for a single UE, and may save more air interface resources.
As an optional embodiment, the network device obtains the area identifier corresponding to the cell, where the area identifier includes at least one of the following:
the network equipment receives cell information of the cell and an area identifier corresponding to the cell, which are sent by a base station;
and the network equipment determines the cell information of the cell and the area identifier corresponding to the cell through static configuration of network management.
In this embodiment, a network device (e.g., a positioning server) may obtain an area identifier corresponding to a cell in the following two ways:
in a first manner, the Cell information and the area identifier may be obtained from the base station, that is, the base station may report the Cell information (for example, information such as PCI, cell-ID, or CGI) of the base station and the area identifier corresponding to the Cell to the positioning server.
In the second mode, the location server may be configured by network management (O & M, i.e., operation and maintence) statically with Cell information (e.g., PCI, cell-ID, or CGI information), and with an area identifier corresponding to the Cell.
