[0004] 5G lightweight terminals are proposed in the New Radio (NR) system. While ensuring service requirements and performance, terminal tailoring aims to reduce terminal costs, minimize size, and reduce power consumption, thereby promoting the large-scale application of 5G terminals. However, due to the different capabilities of lightweight (Redcap) terminals and non-lightweight non-Redcap terminals, some functions and capabilities of Redcap terminals are reduced. Therefore, base stations need to consider supporting Redcap functions by adjusting the overall bandwidth part (BWP) and corresponding radio channel resource planning, and configure a BWP with appropriate bandwidth when Redcap terminals access. In addition, in the physical layer Sounding Reference Signal (SRS) module, because SRS transmission is divided into time domain hopping and frequency domain hopping, how to accurately determine the hopping position of each SRS resource of lightweight terminals in the frequency domain hopping mode is currently an urgent problem that needs to be solved.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0064] In the 3rd Generation Partnership Project Long Term Evolution (3GPP LTE) system, to assist the evolutionary Node B (eNodeB) in uplink channel measurement, the base station configures terminals within its cell to transmit sounding reference signals (SRS) on specific time-frequency resources. Based on the received SRS measurement results, the base station can perform frequency-domain scheduling on the terminal's Physical Uplink Shared Channel (PUSCH) transmission and determine the modulation and coding scheme used for uplink traffic channel transmission, thereby improving uplink spectrum utilization.
[0065] The resource determination method, network device, apparatus, and storage medium of the embodiments of the present application are described below with reference to the accompanying drawings.
[0066] FIG1 is a flow chart of a resource determination method provided in an embodiment of the present application.
[0067] The resource determination method of the embodiment of the present application can be applied to network equipment, such as access network equipment or core network equipment.
[0068] The access network device is exemplified by a base station. A base station may include multiple cells that provide services to terminal devices. Depending on the specific application scenario, a base station may also be referred to as an access point, or may be a device in the access network that communicates with wireless terminal devices over the air interface through one or more sectors, or may be referred to by other names. The access network device can be used to convert received air frames into and out of Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communications network. The access network device also coordinates attribute management of the air interface. For example, the access network device involved in the embodiments of the present application may be an access network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), an access network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), an evolutionary access network device (eNB or e-NodeB) in the Long Term Evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), a home evolved Node B (HeNB), a relay node, a femto, a pico, etc. In some network structures, a base station may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.
[0069] A core network device can be a single device that includes one or more network elements, or it can be multiple devices or device groups that each include all or part of one or more of the aforementioned network elements. A network element can be virtual or physical. The core network, for example, includes at least one of the Evolved Packet Core (EPC), the 5G Core Network (5GCN), and the Next Generation Core (NGC).
[0070] The terminal device may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. The names of terminal devices may vary in different systems. For example, in a 5G system, a terminal device may be referred to as a user equipment (UE). A wireless terminal device may communicate with one or more core network (CN) devices via a radio access network (RAN). A wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device may exchange voice and / or data with a radio access network. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, and personal digital assistants (PDAs). The wireless terminal device may also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, etc., which may be selected according to actual needs.
[0071] As shown in FIG1 , the resource determination method includes the following steps 101 to 103 .
[0072] Step 101: determine a first index of a starting physical resource block (PRB) of an i-th sounding reference signal (SRS) resource of a terminal, where i is a positive integer less than or equal to n, and n is the number of frequency hopping times of the SRS resource associated with the terminal.
[0073] Here, SRS is the abbreviation of Sounding Reference Signal (SRS), and PRB is the abbreviation of Physical Resource Block (PRB).
[0074] The first index is the position index of the starting physical resource block of the i-th SRS resource in the terminal.
[0075] In some possible implementation forms, when i is 1, the offset of the SRS resource on the frequency-domain PRB may be determined as the first index.
[0076] In the present application, when i is 1, the corresponding SRS resource can be considered as the first SRS resource of the terminal. At this time, the offset of the SRS resource on the frequency domain PRB can be determined as the index of the starting physical resource block.
[0077] In some possible implementations, when i is greater than 1 and less than or equal to n, the third index of the starting PRB of the i-1th SRS resource can be updated based on the frequency domain length of each SRS resource of the terminal to obtain the first index.
[0078] The frequency domain length of the SRS resource is the number of PRBs to which the SRS resource is mapped.
[0079] The third index is the position index of the starting PRB of the configured (i-1)th SRS resource.
[0080] In the present application, when i is greater than 1 and less than or equal to n, when the third index of the starting PRB of the i-1th SRS resource is updated based on the frequency domain length of each SRS resource, the first index can be determined by calculating the sum of the third index and the frequency domain length of the i-1th SRS resource.
[0081] Step 102: When the terminal is a lightweight terminal, determine a reference index of the SRS resource of the terminal.
[0082] The reference index is the position index of the frequency hopping reference point of the SRS resource of the terminal.
[0083] In some possible implementation forms, when the second index of the starting PRB of the BWP associated with the terminal is greater than the offset of the SRS resource on the frequency-domain PRB, the second index may be determined as the reference index.
[0084] Among them, BWP is the abbreviation of Bandwidth Part (BWP).
[0085] The second index is the position index of the starting PRB of the BWP associated with the terminal in the entire bandwidth.
[0086] In this application, the second index of the starting PRB of the BWP associated with the terminal Greater than the offset n of the SRS resource in the frequency domain PRB shift In this case, the reference index of the SRS resource of the terminal can be considered to be the position of the starting position subcarrier of the current BWP. At this time, the second index can be determined as the reference index.
[0087] In some possible implementation forms, when the second index of the starting PRB of the BWP associated with the terminal is less than or equal to the offset of the SRS resource on the frequency domain PRB, the reference index can also be determined as the index of the starting PRB of the common resource block.
[0088] In this application, the second index of the starting PRB of the BWP associated with the terminal Less than or equal to the offset n of the SRS resource in the frequency domain PRB shift In this case, the reference index of the SRS resource of the terminal can be considered as the position of the starting subcarrier of the common resource block. At this time, the index of the starting PRB of the common resource block can be determined as the reference index.
[0089] Step 103: Determine the target index of the starting PRB of the i-th SRS resource of the terminal according to the first index and the reference index.
[0090] The target index is the absolute position index of the starting PRB of the SRS resource of the terminal in the entire bandwidth.
[0091] In the present application, after obtaining the first index and the reference index, the target index of the starting PRB of the i-th SRS resource corresponding to the terminal can be determined by calculating the sum of the first index and the reference index.
[0092] For example, as shown in Figure 2, Figure 2 is a schematic diagram of determining the position of the physical resource block PRB in the bandwidth provided by an embodiment of the present application, wherein Redcap is the abbreviation of reduced-capability (Redcap). Taking 100M bandwidth and 30KHZ subcarrier as an example, there are 273 PRBs in total, and the entire bandwidth is divided into 3 BWPs, of which bwp-2 is allocated to the Redcap terminal, which occupies a total of 51 PRBs. When the Redcap terminal sends the first SRS resource, the first index of its corresponding starting PRB is 0, and the reference index of the SRS resource is 50. At this time, it can be determined that the target index of the starting PRB of the first SRS resource of the terminal is 0+50=50.
[0093] It should be noted that this application calculates the target index of the starting PRB of the SRS resource of the terminal based on the relevant definition of the mapping part of the SRS module and frequency domain resources in the Release 17 protocol (R17).
[0094] In an embodiment of the present application, the first index of the starting physical resource block (PRB) of the i-th sounding reference signal (SRS) resource of the terminal is first determined. If the terminal is a lightweight terminal, the reference index of the SRS resource of the terminal is determined. Then, based on the first index and the reference index, the target index of the starting PRB of the i-th SRS resource of the terminal is determined. Thus, by determining the absolute position of each SRS resource in the entire bandwidth based on the reference index of the SRS resource of the lightweight terminal and the first index of the starting PRB of each SRS resource, the accuracy and reliability of the determined position of each SRS resource are guaranteed, ensuring that the lightweight terminal can reliably send the SRS resource, and providing conditions for achieving reliable communication of the lightweight terminal.
[0095] FIG3 is a flow chart of a resource determination method provided in an embodiment of the present application.
[0096] As shown in FIG3 , the resource determination method includes the following steps 301 to 304 .
[0097] Step 301: determine the first index of the starting physical resource block (PRB) of the i-th sounding reference signal (SRS) resource of the terminal, where i is a positive integer less than or equal to n, and n is the number of frequency hopping times of the SRS resource associated with the terminal.
[0098] Step 302: When the terminal is a lightweight terminal, determine a reference index of the SRS resource of the terminal.
[0099] Step 303: Determine the target index of the starting PRB of the i-th SRS resource of the terminal according to the first index and the reference index.
[0100] Among them, the specific implementation forms of steps 301 to 303 can refer to the detailed description of other embodiments of the present application and will not be repeated here.
[0101] Step 304: Send the target index of the starting PRB of each SRS resource among the n SRS resources of the terminal to the terminal.
[0102] In the present application, after determining the target index of the starting PRB of the i-th SRS resource of the terminal, and the target index of the starting PRB of each of the n SRS resources of the terminal, the corresponding target index may be sent to the terminal.
[0103] In an embodiment of the present application, the first index of the starting physical resource block (PRB) of the i-th sounding reference signal (SRS) resource of the terminal is first determined. If the terminal is a lightweight terminal, the reference index of the SRS resource of the terminal is determined. Then, based on the first index and the reference index, the target index of the starting PRB of the i-th SRS resource of the terminal is determined. Finally, the target index of the starting PRB of each SRS resource of the terminal's n SRS resources is sent to the terminal. Thus, by determining the absolute position of each SRS resource in the entire bandwidth based on the reference index of the SRS resource of the lightweight terminal and the first index of the starting PRB of each SRS resource, and sending it to the terminal, it is ensured that the lightweight terminal can reliably send the SRS resource, providing conditions for achieving reliable communication of the lightweight terminal.
[0104] FIG4 is a flow chart of a resource determination method provided in an embodiment of the present application.
[0105] As shown in FIG4 , the resource determination method includes the following steps 401 to 404 .
[0106] Step 401: determine the first index of the starting physical resource block (PRB) of the i-th sounding reference signal (SRS) resource of the terminal, where i is a positive integer less than or equal to n, and n is the number of frequency hopping times of the SRS resource associated with the terminal.
[0107] Step 402: When the terminal is a lightweight terminal, determine a reference index of the SRS resource of the terminal.
[0108] Step 403: Determine the target index of the starting PRB of the i-th SRS resource of the terminal according to the first index and the reference index.
[0109] The specific implementation of steps 401 to 403 can refer to the detailed description of other embodiments of the present application and will not be repeated here.
[0110] Step 404 : Determine a fourth index of a first end PRB of the n th SRS resource based on a target index of a start PRB of the n th SRS resource of the terminal and a frequency domain length of each SRS resource.
[0111] The first ending PRB is the last PRB in the frequency domain of the nth SRS resource.
[0112] The fourth index is the absolute position of the last PRB in the frequency domain of the n-th SRS resource in the entire bandwidth.
[0113] For example, the target index of a certain SRS resource of the terminal is PRB#0, and the frequency domain length of the SRS resource is 48 PRBs. Then the fourth index of the first end PRB of the SRS resource is PRB#47.
[0114] Furthermore, the resource determination method also includes step 405, when the fourth index is less than the fifth index of the second end PRB of the BWP associated with the terminal, based on the characteristic value of the first end PRB, the PRB between the first end RPB and the second end PRB in the BWP is assigned a characteristic value.
[0115] The second end PRB is the last PRB included in the BWP associated with the terminal.
[0116] The fifth index is the absolute position of the last PRB included in the BWP associated with the terminal in the entire bandwidth.
[0117] Taking the above example as an example, the BWP associated with the terminal includes PRBs PRB#0 to PRB#50, the fourth index is PRB#47, and the fifth index is PRB#50. The fourth index is less than the fifth index. At this time, based on the characteristic value of the PRB corresponding to index PRB#47, the PRBs corresponding to index PRB#48, index PRB#49, and index PRB#50 can be assigned values respectively. As shown in Figure 5, Figure 5 is a schematic diagram of assigning values to spare physical resource blocks PRBs provided in an embodiment of the present application.
[0118] In an embodiment of the present application, the first index of the starting physical resource block PRB of the i-th sounding reference signal SRS resource of the terminal is first determined. When the terminal is a lightweight terminal, the reference index of the SRS resource of the terminal is determined. Then, based on the first index and the reference index, the target index of the starting PRB of the i-th SRS resource of the terminal is determined. Then, based on the target index of the starting PRB of the n-th SRS resource of the terminal and the frequency domain length of each SRS resource, the fourth index of the first ending PRB of the n-th SRS resource is determined. When the fourth index is less than the fifth index of the second ending PRB of the BWP associated with the terminal, based on the characteristic value of the first ending PRB, the PRB between the first ending RPB and the second ending PRB in the BWP is assigned a characteristic value. Thus, when the index of the ending PRB corresponding to the SRS resource is less than the index of the ending PRB of the BWP associated with the terminal, the characteristic value of the adjacent PRB is assigned to the PRB without a characteristic value in the BWP, thereby providing conditions for improving the communication effect of the lightweight terminal.
