[0126] In some embodiments, network device 102 may include at least one of access network device and core network device.

[0127] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0130] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0131] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices comprising one or more network elements, or it may be a physical entity. The core network may include, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), or a next-generation core (NGC).

[0132] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0133] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected to each other or may be connected in any way. The connection may be direct or indirect, wired or wireless.

[0134] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), Super 3G, IMT-Advanced, 4th Generation Mobile Communication System (4G), 5th Generation Mobile Communication System (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), and IEEE 802.16 (WiMAX, a registered trademark), IEEE 802.20, ultra-wideband (UWB), Bluetooth (a registered trademark), public land mobile network (PLMN), device-to-device (D2D) systems, machine-to-machine (M2M) systems, internet of things (IoT) systems, vehicle-to-everything (V2X) systems, systems utilizing other power control methods, and next-generation systems extended from them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0135] In this embodiment of the disclosure, the accuracy of positioning measurement is improved by bandwidth aggregation of the sounding reference signal (SRS) or the SRS set.

[0136] Figure 1b This is a schematic diagram illustrating bandwidth aggregation of an SRS set according to an embodiment of the present disclosure.

[0137] like Figure 1b As shown, terminal 101 transmits SRS set1 and SRS set2 on component carrier (CC)1, and SRS set3 and SRS set4 on CC2. When network device 102 receives SRS sets for positioning measurement, it performs bandwidth aggregation on SRS set2 on CC1 and SRS set4 on CC2 to obtain the positioning measurement result.

[0138] Optionally, the transmit power of the SRS or SRS set under each carrier satisfies the following relationship:

[0139]

[0140] Among them, P CMAX,f,c (i) represents the maximum transmit power of terminal 101 during the i-th transmission. M represents the target receive power of the network device. SRS,b,f,c (i) represents the bandwidth of the SRS. PL represents the path compensation factor. b,f,c (q d ) represents the path loss value estimated based on the downlink reference signal, b represents the activated uplink bandwidth portion, f represents the carrier frequency, c represents the serving cell, i represents the i-th transmission, and q represents the path loss value estimated based on the downlink reference signal. s Indicates index, q d This indicates the downlink reference signal index used for road loss estimation.

[0141] Optionally, in carrier aggregation scenarios, if the number of channels / signals simultaneously transmitted under each CC exceeds the terminal's maximum transmit power, based on predefined priorities, the transmit power of high-priority channels / signals is guaranteed, while the transmit power of low-priority channels / signals is downgraded. For channels / signals of the same priority, the transmit power of the channels / signals on the primary cell is guaranteed.

[0142] Optionally, when sending an SRS or SRS set, the SRS sequence under a certain CC needs to be multiplied by a weighting coefficient β when mapping it to physical resources. SRS Furthermore, it is necessary to ensure that the sum of the power of each RE is equal to the transmit power determined above. The SRS weighting coefficients under different CCs are determined separately, and there is no requirement that they be the same.

[0143] Optionally, to improve the accuracy of positioning measurements, bandwidth aggregation of SRS or SRS sets on different carriers can be considered. For bandwidth-aggregated SRS, it may be necessary to ensure that the subcarrier power of the SRS or SRS set on all CCs is the same. Therefore, how to determine the transmit power of the SRS or SRS set used for bandwidth aggregation is a problem that needs to be solved. Furthermore, if the transmit power of the SRS or SRS set used for bandwidth aggregation exceeds the user's transmit power limit when used on different CCs, how to handle this situation is currently unclear.

If network device 102 indicates that the priority of SRS1 is higher than the priority of SRS2, then the first transmit power of SRS1 is the second transmit power, and the first transmit power of SRS2 is the third transmit power after backing down based on the second transmit power.

[0343] In some embodiments, the above methods may include the methods described in the embodiments related to the communication system 100, terminal 101, network device 102, etc., which will not be repeated here.

[0344] This disclosure also provides a power control method, as described below:

[0345] Method 1: Ensure that the transmit power of each resource element (RE) is the same.

[0346] In some embodiments, the system receives indication information from the network to determine which SRS or sets of SRS are probe reference signals (SRS) or sets of SRS that need to be aggregated.

[0347] Optionally, the first indication method is to configure an identifier (link ID) for each SRS or SRS set, and SRSs with the same link ID are the SRSs that need to be aggregated.

[0348] Optionally, the second indication method is to configure different lists of detection reference signals (SRS-pos set) for positioning, where the SRS or SRS set in the list are the SRS or SRS set that need to be aggregated.

[0349] In some embodiments, the transmit power of the SRS or SRS set to be aggregated is determined: the transmit power of the SRS or SRS set under each component carrier (CC) is determined according to the power control parameters configured for each SRS or SRS set, and the transmit power of the SRS or SRS set under each component carrier (CC) is determined according to existing formulas. It is assumed that the transmit powers of CC1, CC2, and CC3 determined according to their respective power control parameters are P1, P2, and P3.

[0350] Optionally, if (P1+P2+P3)≤maximum transmit power (Pcmax), then the total transmit power is P1+P2+P3, and the transmit power P of each subcarrier of the aggregated SRS is... RE The sum of the transmit power is (P1+P2+P3) / sum(REs in all CCs). To ensure the transmit power of each subcarrier, when the SRS on each CC is mapped to physical resources, the weighting coefficient β of the symbol for each RE needs to be the same. The value of β needs to ensure that the total transmit power is (P1+P2+P3). Therefore, in practice, the transmit power on CC1 is Pcc1=P RE ×Sum(REs in CC1), the actual transmit power on other CCs is similar.

[0351] Optionally, if (P1+P2+P3)>Pcmax, then the total transmit power is Pcmax. Then the transmit power P of each subcarrier performing aggregated SRS is... RE The sum of transmit power is (Pcmax) / sum(REs in all CCs). When mapping SRS or SRS sets on each CC to physical resources, the weighting coefficient β of each RE symbol must be the same, and the total transmit power must be Pcmax. The actual transmit power of the SRS or SRS sets on each CC is the transmit power of each subcarrier multiplied by the number of REs.

[0352] Method 2: Ignoring the fact that the power of each RE is the same

[0353] In some embodiments, the system receives indication information from the network to determine which SRSs or SRS sets are SRSs or SRS sets that need to be aggregated.

[0354] Alternatively, the indication method is the same as in Method 1.

[0355] In some embodiments, the transmit power of the SRS or SRS set to be aggregated is determined: the transmit power of the SRS or SRS set under each CC is determined based on the power control parameters configured for each SRS or SRS set. Assume that the transmit powers of CC1, CC2, and CC3 determined according to their respective power control parameters are P1, P2, and P3, respectively.

[0356] Alternatively, if (P1+P2+P3)>Pcmax.

[0357] Optionally, the transmission of SRS or SRS set under the member carrier with better channel quality is guaranteed, while power back-off is performed on the SRS or SRS set of other CCs.

[0358] Optionally, Pcmax can be divided equally among the CCs, or proportionally. The proportion can be determined based on the desired P1, P2, and P3. For example, the actual transmit power of CC1 is Pcmax*P1 / (P1+P2+P3).

[0359] In the embodiments disclosed herein, each step can be implemented as an independent embodiment. Some or all of the steps, and their optional implementations, can be arbitrarily combined with some or all of the steps in other embodiments, or can be arbitrarily combined with the optional implementations of other embodiments.

[0360] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0361] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0362] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
