Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a resource allocation method, apparatus, terminal and network equipment. Background Technology

[0002] Currently, NR (New Radio) terminals search for and measure PRS (Positioning Reference Signals) signals based on PRS resource information provided by the cellular network, thereby supporting high-precision positioning based on the cellular network. However, if the cellular network pre-configures too many PRS resources for the NR terminal, it will significantly reduce the efficiency of the terminal in measuring and searching for valid PRS signals, and will also increase the terminal's positioning latency.

[0003] In some scenarios, such as when the terminal is in a connected state, the network can effectively configure the PRS signal in real time based on the serving base station where the terminal is located. However, in other scenarios, the network may not be able to configure the PRS for the terminal in real time, and PRS resources need to be pre-configured. For example, if a terminal wakes up in an inactive state (i.e., not connected state) and needs to measure the PRS to start positioning, pre-configured PRS resources are required to reduce the latency of real-time positioning services.

[0004] However, in this scenario where PRS resources are pre-configured, the current resource configuration method is difficult to configure PRS resources reasonably, resulting in excessive consumption of air interface resources and relatively low positioning efficiency. Summary of the Invention

The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN.

[0093] Explanation regarding NR SIAID:

[0094] Both the MIB (Master Information Block) and SIB1 (System Information Block Type 1, which contains cell access information and scheduling information for SIBs (excluding SIB1)) messages are cell-level specific messages. Any other system message containing a SIB (System Information Block) can be configured as a cell-level or region-level system message. Region-level SIBs are universal within the defined SI (System Information) region, which can contain one or more cells.

[0095] The SIAID is 24 bits long and unique within the PLMN (Public Land Mobile Network). It is used solely to identify the area-specific SIB (System Instruction Message) coverage area. Each cell broadcasts only one SIAID, which is used in conjunction with the PLMN ID. The SIAID indicates which system message cell the cell belongs to. If the SIB message is area-specific, the SIAID indicates which system message cell the cell belongs to.

[0096] like Figure 2 As shown, an embodiment of the present invention provides a resource allocation method, including:

[0097] Step 201: The terminal obtains the resource configuration information of the first resource; the resource configuration information includes: the region identifier to which the first resource belongs and / or the effective time length of the first resource.

[0098] In this step, the terminal obtains the first resource by acquiring its resource configuration information. This first resource is used to search for signals (e.g., a positioning reference signal, PRS). For example, the UE can obtain the resource configuration information via the LPP (LTE Positioning Protocol). The resource configuration information can be pre-configured.

[0099] Step 202: The terminal determines the validity of the first resource based on the region identifier to which the first resource belongs and / or the validity period of the first resource.

[0100] In this embodiment of the invention, the terminal can learn whether the first resource is valid through resource configuration information, and then decide whether to perform a signal search on the first resource based on the validity of the first resource. This can reduce the time and power consumption required for the terminal to search for signals on invalid first resources, improve the efficiency of the terminal, and reduce the consumption of air interface resources.

[0101] As an optional embodiment, the terminal determines the validity of the first resource based on the region identifier to which the first resource belongs, including:

[0102] The terminal compares the region identifier to which the first resource belongs with the region identifier corresponding to the cell where the terminal is currently located;

[0103] If the area identifier to which the first resource belongs is the same as the area identifier corresponding to the cell where the terminal is currently located, the first resource is determined to be valid.

[0104] In this implementation, the area identifier can be SIAID, TAC, RNA ID, or REARID. By comparing the area identifier to which the first resource belongs with the area identifier of the cell to which the terminal is currently located (i.e., the area identifier to which the terminal currently belongs), the terminal can determine whether the first resource is valid for the terminal. This allows the terminal to decide whether to perform a signal search on the first resource based on its validity, thereby reducing the time spent searching for signals on invalid first resources, avoiding unnecessary power consumption, reducing latency, and improving efficiency.

[0105] As another optional embodiment, the terminal determines the validity of the first resource based on the effective duration of the first resource, including:

[0106] Based on the effective time length of the first resource, determine whether the time length for which the terminal stores the resource configuration information is less than or equal to the effective time length;

[0107] If the duration for which the terminal stores the resource configuration information is less than or equal to the effective duration, the first resource is determined to be valid.

[0108] It should be noted that the effective time length of the first resource indicates how long the first resource can be valid. After the terminal obtains the resource configuration information, it can store the resource configuration information. When the terminal is about to search for a signal on the first resource, it can first compare the length of time the resource configuration information has been stored on the terminal with the effective time length of the first resource, and then determine the validity of the first resource based on the relationship between the two.

[0109] In this implementation, the terminal can determine whether the first resource is currently valid for the terminal by the effective time length of the first resource. This allows the terminal to decide whether to perform a signal search on the first resource based on its validity, thereby reducing the time spent searching for signals on invalid first resources, avoiding unnecessary power consumption, reducing latency, and improving efficiency.

[0110] As another optional embodiment, the terminal determines the validity of the first resource based on the region identifier to which the first resource belongs and the validity period of the first resource, including:

[0111] If the area identifier to which the first resource belongs is the same as the area identifier corresponding to the cell where the terminal is currently located, and the length of time for which the terminal stores the resource configuration information is less than or equal to the effective time length, then the first resource is determined to be valid.

[0112] It should be noted that after determining the validity of the first resource, the terminal can perform signal search in the following manner:

[0113] Method 1: If the first resource is valid, then a signal search is performed on the first resource; if the first resource is invalid, then the signal search on the first resource is abandoned.

[0114] In this approach, searching for signals on valid first resources can quickly improve the speed and efficiency of the terminal's signal search, while abandoning the search for signals on invalid first resources can further improve the speed and efficiency of the terminal's search for valid signals.

[0115] Method 2: When starting a signal search, prioritize searching for the signal on the valid first resource. If the signal measured by the terminal (e.g., PRS signal) is insufficient, then attempt to search for the signal on the invalid first resource.

[0116] As an optional embodiment, the method further includes:

[0117] Based on the validity of the first resource, determine the priority of the first resource;

[0118] A signal search is performed on the first resource with the highest priority.

[0119] In this implementation, the terminal can determine whether the first resource is valid by combining the area identifier to which the first resource belongs and the effective time length of the first resource. This allows the terminal to decide whether to perform a signal search on the first resource based on its validity, thereby reducing the time the terminal spends searching for signals on invalid first resources, avoiding unnecessary power consumption, reducing latency, and improving efficiency.

[0120] It is understandable that for the first resource with low priority, the search for a signal on that first resource can be abandoned directly, or the signal measured by the terminal (such as the PRS signal) can be searched on the first resource with low priority when it is insufficient.

[0121] As an optional embodiment, after performing a signal search on the first resource with high priority, the method further includes:

[0122] A signal search is performed on the first resource, which has a low priority.

[0123] In this embodiment, when the signal measured by the terminal (e.g., the PRS signal) is insufficient, a signal search can be attempted in an invalid first resource.

[0124] As an optional embodiment, determining the priority of the first resource based on its validity includes at least one of the following:

[0125] If the first resource is valid, the priority of the first resource is determined to be high;

[0126] If the first resource is invalid, the priority of the first resource is determined to be low.

[0127] In this way, the terminal can prioritize searching for signals on the valid first resource (i.e., the first resource with higher priority).

[0128] As an optional embodiment, the region identifier includes at least one of the following:

[0129] System message: Cell Identifier (SIAID);

[0130] Tracking area code (TAC);

[0131] Access network notification area identifier RNA ID;

[0132] REARID is the effective region for resource allocation.

[0133] The following provides specific examples of the solutions provided in the embodiments of this application.

[0134] In Example 1, the terminal determines the validity of the first resource based on the region identifier to which the first resource belongs:

[0135] Step 1: When the terminal is ready to use the resource configuration information of the first resource, it compares the SIAID (or TAC, or RNA ID, or REARID) in the SIB1 message obtained by the current serving cell with the area identifier (i.e. AreaID, which can be SIAID, TAC, RNA ID, or REARID) to which the first resource belongs in the resource configuration information.

[0136] If the two are consistent, the first resource is determined to be within the valid area, i.e., the first resource is valid; if the two are inconsistent, the first resource is determined to be outside the valid area, i.e., the first resource is invalid. The terminal can reduce the search priority of the first resource (i.e., the priority of the first resource). In this way, the terminal can prioritize searching for signals on the valid first resource, that is, prioritize searching for signals within the valid area.

[0137] Step 2: When starting the search for signals indicated by resource configuration information (such as positioning signals), prioritize searching for signals within the valid area, such as SSB (Synchronization Signal and PBCH block) and PRS signals. This allows for rapid improvement in the UE's signal search speed and efficiency by searching within the valid area.

[0138] Step 3: When the signal measured by the UE (e.g., PRS) is insufficient, try to search for signals that are not within the valid area, i.e., try to search for signals on invalid first resources.

[0139] Understandably, after determining that the first resource is invalid, the terminal can also give up searching for signals that are not in the valid area, for example, it can stop searching for the signal corresponding to the first resource. This can further improve the speed and efficiency of the UE searching for valid signals.

[0140] Example 2: The terminal determines the validity of the first resource based on the effective duration of the first resource.

[0141] Step 1: After the terminal obtains the resource configuration information of the first resource, it can store the resource configuration information.

[0142] Step 2: When the terminal is ready to use the resource configuration information, it can first compare the duration (i.e., time length) of the resource configuration information stored on the terminal with the effective time length of the first resource.

[0143] If there is no timeout (i.e., the time the terminal stores the resource configuration information is less than or equal to the valid time period), the first resource is determined to be still valid, and the UE can then consider searching for signals on that first resource, such as searching for the signal corresponding to that first resource. If the time the terminal stores the resource configuration information exceeds the valid time period (i.e., the valid duration), the first resource is determined to be invalid. In this case, the terminal can lower the search priority for that first resource. This allows the terminal to prioritize searching for signals corresponding to valid first resources (such as SSB and PRS), rapidly improving the UE's signal search speed and efficiency.

[0144] Step 3: When starting to search for signals indicating resource configuration information, prioritize searching for signals corresponding to the first valid resource (e.g., SSB and PRS).

[0145] Step 4: If the signal measured by the UE (e.g., PRS) is insufficient, try searching for the signal corresponding to the first resource that is no longer valid.

[0146] Understandably, after determining that the first resource is invalid, the terminal can also give up searching for signals on the first resource, for example, it can stop searching for signals corresponding to the first resource. This can further improve the speed and efficiency of the UE searching for valid signals.

[0147] In summary, in this embodiment of the invention, the terminal can learn whether the first resource is valid through resource configuration information, and then decide whether to perform a signal search on the first resource based on the validity of the first resource. This reduces the time and power consumption required for the terminal to search for signals on invalid first resources, improves the efficiency of the terminal, and reduces the consumption of air interface resources.

[0148] like Figure 3 As shown, this embodiment of the invention also provides a resource allocation method, including:

[0149] Step 301: The network device obtains the area identifier corresponding to the cell.

[0150] Step 302, the network device sends resource configuration information of the first resource to the terminal; the resource configuration information includes: the area identifier to which the first resource belongs and / or the validity period of the first resource.

[0151] In this step, network devices (such as location servers) can place the area identifier to which the first resource belongs in the resource configuration information content pre-configured by LPP and send it to the terminal via the LPP protocol.

[0152] Specifically, the positioning server can pre-configure resource information (such as PRS resources) on the LPP interface and provide it to the terminal, informing the terminal of the downlink first resource. This resource configuration information includes not only the existing resource configuration information in the time, frequency, and spatial domains, but also an indication of the area identifier to which the resource configuration belongs (e.g., the area identifier to which the first resource belongs). In this way, by assigning different first resources to different area identifiers, the regional validity of the first resource is distinguished. The area identifier can be the SIAID, TAC, RNA ID, or REARID of the cell to which the first resource belongs.

[0153] In this embodiment of the invention, the network device can pre-configure the signal of the terminal in a reasonable manner by configuring the resource configuration information, so that the terminal can know whether the first resource is valid through the resource configuration information, and then decide whether to search for the signal on the first resource based on the validity of the first resource. This can reduce the time and power consumption required for the terminal to search for the signal on the invalid first resource, improve the efficiency of the terminal, and reduce the consumption of air interface resources.

[0154] It should be noted that in existing technologies, the list of cell IDs for valid areas is usually configured directly in resources (such as PRS resources), which consumes too much air interface resources. For example, using the neighbor cell list concept defined in SIB3 (System Information Block Type 3, Serving Cell Reselection Information), 16 valid cell IDs are configured for each resource, meaning that the configured resource is valid in all 16 cells. The maximum value of PhysCellID (i.e., PCI) in the protocol is 1008. If the existing conventional configuration method is used, configuring a single resource requires 16 * 10 bits = 160 bits, so configuring 256 resources would require 256 * 16 * 10 bits = 40 Mbits of air interface resources. It can be seen that this simple cell list configuration method consumes a large amount of air interface resources. However, when using the resource configuration method of this embodiment of the invention, configuring a single resource consumes a maximum of 24 bits of air interface resources (for example, when the area identifier is SIAID, the length of SIAID is 24 bits). In other words, when 256 resources need to be configured, the resource configuration method of this embodiment can save 256*(160-24)=34816 bits of air interface resources for a single UE, which is about 34Mbit, thus saving a lot of air interface resources.

[0155] As an optional embodiment, the network device obtains the area identifier corresponding to the cell, including at least one of the following:

[0156] The network device receives the cell information of the cell and the area identifier corresponding to the cell from the base station;

[0157] The network device determines the cell information and the area identifier corresponding to the cell through static configuration of network management.
