Background technique

In order to support terminals to effectively obtain information through channels under various terminal transceiver capabilities, different antenna switching configurations (antenna switching configurations) are set for terminals in the communication system. Different antenna switching configurations correspond to different SRSs.

Moreover, for a certain antenna switching configuration, different SRS resource sets may also be configured corresponding to different antenna ports. However, the antenna structure design of the current antenna switching configuration and the configuration of the SRS resource set will cause the SRS transmission power imbalance in different time slots, which will also affect the performance of the downlink channel state information (CSI). This causes the problem that the actual coverage of different antenna ports is inconsistent.

When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure.

The SRS power control method provided by the embodiments of the present disclosure can be applied to the wireless communication system shown in FIG. 1 . Referring to FIG. 1 , the wireless communication system includes network devices and terminals. The terminal is connected to the network equipment through wireless resources, and performs data transmission.

It can be understood that the wireless communication system shown in FIG. 1 is only for schematic illustration, and the wireless communication system may also include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices, etc. Not shown in Figure 1. The embodiment of the present disclosure does not limit the number of network devices and terminals included in the wireless communication system.

It can be further understood that the wireless communication system in the embodiment of the present disclosure is a network that provides a wireless communication function. Wireless communication systems can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA) , frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency-division multiple access (single Carrier FDMA, SC-FDMA), carrier sense Multiple Access/Conflict Avoidance (Carrier Sense Multiple Access with Collision Avoidance). According to the capacity, speed, delay and other factors of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network can also be called a new wireless network ( New Radio, NR). For convenience of description, the present disclosure sometimes simply refers to a wireless communication network as a network.

Further, the network equipment involved in this disclosure may also be referred to as radio access network equipment. The wireless access network device may be: a base station, an evolved base station (evolved node B, base station), a home base station, an access point (access point, AP) in a wireless fidelity (wireless fidelity, WIFI) system, a wireless relay Node, wireless backhaul node, transmission point (transmission point, TP) or transmission and reception point (transmission and reception point, TRP), etc., can also be gNB in the NR system, or it can also be a component or a part of equipment that constitutes a base station wait. It should be understood that in the embodiments of the present disclosure, no limitation is imposed on the specific technology and specific device form adopted by the network device. In the present disclosure, a network device can provide communication coverage for a specific geographic area, and can communicate with terminals located in the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network device may also be a vehicle-mounted device.

Further, the terminals involved in this disclosure can also be referred to as terminal equipment, user equipment (User Equipment, UE), mobile station (Mobile Station, MS), mobile terminal (Mobile Terminal, MT), etc. A device providing voice and/or data connectivity, for example, a terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, and the like. At present, examples of some terminals are: Smartphone (Mobile Phone), Customer Premise Equipment (CPE), Pocket Personal Computer (PPC), PDA, Personal Digital Assistant (PDA) , laptops, tablets, wearable devices, or vehicle-mounted devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiment of the present disclosure does not limit the specific technology and specific device form adopted by the terminal.

In related technologies, multiple transmitting antennas and receiving antennas are used at the transmitting end and the receiving end respectively, so that signals are transmitted and received through the multiple antennas at the transmitting end and the receiving end. Multi-transmission and multi-reception can be realized through multiple antennas. Without increasing spectrum resources and antenna transmission power, the system channel capacity can be doubled, and the data throughput and signal-to-noise ratio can be improved, thereby improving system performance and communication quality.

In order to support various terminals with various transceiver capabilities to effectively obtain downlink information through channels, different antenna switching configurations are set for terminals in the communication system. Different antenna switching configurations correspond to different SRSs.

In the 5G NR system, the triggering of SRS resources can include periodic/semi-persistent/aperiodic SRS resource configuration triggering mechanisms. Wherein, all the parameters of the periodic SRS (P-SRS) are configured by high-layer signaling, and after the configuration is performed by the high-layer signaling, the terminal performs periodic transmission according to the configured parameters. All parameters of semi-persistent SRS (SP-SRS) are also configured by high-level signaling. The difference from periodic sounding reference signal (SRS) is that although the corresponding parameters have been configured, the terminal cannot send SRS before receiving the activation command. Once activated, the terminal starts to send SRS, and stops sending SRS until it receives a deactivation command sent by the network device. The activation and deactivation commands of SP-SRS are sent by the MAC layer, which is the MAC CE command. The aperiodic SRS resource (AP-SRS) is triggered by the SRS request in the downlink control signaling (Downlink Control Information, DCI).

In related technologies, the uplink SRS may be periodic SRS, semi-persistent SRS or aperiodic SRS. Narrowband or broadband, single port or multiport. The uplink SRS parameters are configured by the network device to the terminal, and include the number of ports, resource locations in the frequency domain, resource locations in the time domain, sequences, sequence cycle offsets, and the like. In a 5G NR system, SRS resources are mapped on up to six symbols of an uplink slot, as shown in Figure 2, which shows the SRS resource mapping area within a slot.

Wherein, the network device can configure multiple uplink SRS resource sets for the terminal, and one SRS resource set includes one or more SRS resources. One SRS resource can be mapped on N consecutive OFDM symbols, and N can occupy 1, 2, or 4 symbols.

In the latest standard version (R17), it is defined that the terminal can send SRS resources on any symbol, and the length of the SRS resources can also support the maximum transmission of 14 symbols.

Further, in the research of R17, it is considered that the number of antennas of the terminal needs to be further increased, so the number of antennas will be further increased. Currently, a maximum of 6 antennas or a maximum of 8 antennas are indicated. The typical antenna configuration currently defined is {1T6R, 1T8R, 2T6R, 2T8R, [4T6R], 4T8R}, as shown in Table 1 below:

Table 1: SRS antenna switching combinations up to 8 antennas

Tx\Rx 6Rx 8Rx 1T 1T6R 1T8R 2T 2T6R 2T8R 4T 4T6R 4T8R

Among them, in the SRS enhancement of R17, there may be different designs for the realization structure of the antenna switching configuration. For example, by introducing a radio frequency switching network (RF switching Network), different SRS resource sets can also be configured corresponding to different antenna ports for a certain antenna switching configuration. In an example, there may be many different designs for the realization structure that the antenna switching configuration is 4T6R. On the basis of the normal 4 transmit and 4 receive ports, the antenna maps the original 4 transmit antenna ports to 6 physical antenna ports according to the SRS resource configuration method through the radio frequency switching network. Fig. 3 shows a schematic diagram of a 4T6R antenna switching structure according to an exemplary embodiment of the present disclosure. Referring to Fig. 3, for 4 antenna transmit ports (Tx), it needs to be connected to 6 physical antenna ports (AP0, AP1...AP5) through a radio frequency switch circuit. Among them, AP2, AP3, AP4 and AP5 are connected to the TX transmitting antenna of the Wireless Transceiver radio frequency receiver through the RF switching Network, so on the basis of the original 4T4R antenna structure, the intermediate conversion circuit (RF switching Network and Wireless Transceiver radio frequency receiving Machine) realizes the switch to 4T6R, 4T6R is an unbalanced antenna structure, for the SRS resources allocated by AP2, AP3, AP4 and AP5, there may be insertion loss (Insertion loss). Further, one SRS resource corresponding to 4 antenna ports and one SRS resource corresponding to two antenna ports may be configured. These two SRS resources can be configured in the same or different SRS resource sets, wherein, the SRS resources configured for different port numbers, because the traditional power control rules may cause the SRS transmission power in different time slots to be unbalanced Condition.

Fig. 4 shows a schematic structural diagram of another antenna according to an exemplary embodiment of the present disclosure. Among them, the antenna structure shown in Figure 4 is also an unbalanced antenna structure with RF switching Network introduced, there may be insertion loss values, and the transmission power of each antenna port may also be inconsistent.

Due to the existence of the insertion loss value and the unbalanced SRS transmission power in different time slots, there will be inconsistencies in SRS coverage, resulting in problems in the acquisition of Channel State Information (CSI).

In view of this, it is a subject to be studied to control and adjust the SRS power for the unbalanced transmission power of multiple different antenna ports corresponding to different SRS resources under a certain antenna switching configuration.

An embodiment of the present disclosure provides an SRS power control method. When the terminal determines that the transmit power of different antenna ports corresponding to one or more SRS resources of the specified antenna switching configuration is different, based on the SRS power control rule, determine the different antenna ports. The transmission power of different antenna ports can be modified to achieve the same effect of SRS coverage of different antenna ports.

Among them, in the embodiment of the present disclosure, different from the SRS power control rule (for example, the SRS power control rule in TS38.213) for transmitting power control of the antenna port in the related art, the method used in the embodiment of the present disclosure for different antenna ports The SRS power control rule for the SRS coverage of the port (inconsistent SRS coverage for the receiving and receiving ports) is called an enhanced SRS power control rule.

Fig. 5 is a flow chart of an SRS power control method according to an exemplary embodiment. As shown in Fig. 5, the SRS power control method is used in a terminal and includes the following steps.

In step S11, an enhanced SRS power control rule is obtained in response to different transmit powers of different antenna ports corresponding to one or more SRS resources of a specified antenna switching configuration.

In step S12, the transmit power of different antenna ports is determined based on the enhanced SRS power control rule.

In the embodiment of the present disclosure, based on the enhanced SRS power control rule, the terminal determines the transmit power of different antenna ports corresponding to one or more SRS resources configured for antenna switching, and can realize the modification of the transmit power of different antenna ports to achieve Port SRS coverage for consistent effect and improved system performance.

On the one hand, the enhanced SRS power control rules in the embodiments of the present disclosure may be predefined rules. On the other hand, the enhanced SRS power control rule in the embodiment of the present disclosure may be configured by a network device based on network signaling. The terminal obtains the enhanced SRS power control rule sent by the network device.

Wherein, in the embodiments of the present disclosure, the terminal may have the ability to support enhanced control of SRS power, that is, in the embodiments of the present disclosure, the terminal may perform SRS enhanced power control when it is determined that the terminal supports the capability of SRS enhanced power control.

In one embodiment, the terminal may report the terminal capability to the network device to indicate that the terminal has the capability of supporting SRS enhanced power control, so that the network device configures enhanced SRS power control rules for the terminal.

Embodiments of the present disclosure The implementation of the SRS power control method involved in the embodiments of the present disclosure will be described below in combination with practical applications.

In one implementation manner, the power control rule for SRS enhancement includes setting the transmit power of different antenna ports corresponding to one or more SRS resources configured for antenna switching to be the same.

In the embodiment of the present disclosure, for the case where the transmit power of different antenna ports corresponding to one or more SRS resources configured by antenna switching is different, the terminal can recalculate the transmit power so that the one or more SRS resources configured by antenna switching The transmit powers of corresponding different antenna ports are the same.

Fig. 6 is a flow chart showing an SRS power control method according to an exemplary embodiment. As shown in Fig. 6, the SRS power control method is used in a terminal and includes the following steps.

In step S21, determine the total transmission power of the SRS resources corresponding to the multiple different antenna ports in the antenna switching configuration.

In step S22, mean value processing is performed on the total sending power, and the power after mean value processing is used as the sending power of different antenna ports corresponding to one or more SRS resources.

In the embodiment of the present disclosure, after the mean value processing is performed on the total transmission power corresponding to the transmission SRS resources of multiple different antenna ports in the antenna switching configuration, multiple identical transmission powers can be obtained, and then the same transmission power can be used as the antenna switching configuration The transmit power of different antenna ports corresponding to one or more SRS resources of .

In an implementation manner, when the average value processing is performed on the total transmission power of the SRS resources corresponding to the multiple different antenna ports in the antenna switching configuration, it may be performed based on any predefined value. Wherein, for the convenience of calculation, in the embodiment of the present disclosure, the average value processing may be performed on the total transmission power based on the predefined SRS antenna port value.

Wherein, the predefined SRS antenna port value may be determined based on the number of SRS antenna ports corresponding to each of the multiple SRS resources contained in one or more SRS resource sets corresponding to the antenna switching configuration.

Wherein, the predefined SRS antenna port value may be any antenna port value among the SRS antenna port numbers corresponding to each of the multiple SRS resources included in one or more SRS resource sets corresponding to the antenna switching configuration.

In one embodiment, the predefined antenna port value is the maximum number of antenna ports among the numbers of SRS antenna ports corresponding to each of the multiple SRS resources contained in one or more SRS resource sets corresponding to the antenna switching configuration.

In an example, the number of SRS antenna ports corresponding to the multiple SRS resources contained in one SRS resource set corresponding to the antenna switching configuration is respectively {p1, p2,...pn}, and the maximum number of antenna ports is K=max{p1, p2, ...pn}. For example, the SRS resource set configured for the antenna switching configuration includes one SRS resource set corresponding to 4 antenna ports, and one SRS resource set corresponding to two antenna ports, then {p1, p2,...pn} is {2 , 4}, K=max{p1, p2, . . . pn}=max{2, 4}=4.

It is assumed that the total transmission power of multiple different antenna ports corresponding to the antenna switching configuration for transmitting SRS resources is P _SRS,b,f,c (i,q _s ,l). The transmit power of each antenna port in different antenna ports corresponding to one or more SRS resources configured by antenna switching can be expressed as

为对发送总功率进行均值处理后的功率。 Wherein, K is the maximum number of antenna ports among the numbers of SRS antenna ports corresponding to each of the multiple SRS resources included in the antenna switching configuration corresponding to one or more SRS resource sets. P _SRS,b,f,c (i,q _s ,l) is the total transmission power of SRS resources corresponding to multiple different antenna ports configured for antenna switching.
