Description

Method and device for uplink and downlink time resource configuration

Technical field

This application relates to the field of communications, and more specifically, to a method and device for uplink and downlink time resource configuration.

Background technique

With the development of technology, terminal equipment can be dual-linked with two systems. For example, the terminal device can make a double link (DC) (ie, EN-DC scenario) with the LTE system and the NR system. In the EN-DC scenario, a terminal device can communicate with network equipment of a long term evolution (LTE) system on the one hand, and can also communicate with network equipment of a new radio (NR) system on the other hand .

Due to limitations in hardware design of the terminal equipment, in some cases, the terminal equipment cannot send uplink signals to two systems through two uplink radio frequency links at the same time. For example, the terminal device cannot send uplink signals to the network equipment of the LTE system and the network equipment of the NR system through two uplink radio frequency links at the same time.

In the prior art, in order to ensure that uplink signals are sent to the two systems at different times (for example, to send uplink signals to the LTE system and the NR system), time division multiplexing (TDM) can be configured for the system's uplink transmission. Mode, which can send uplink signals to two systems on different subframes of a frame. However, in the prior art, in order to ensure that uplink signals are sent to each system at different times, the system (for example, the LTE system) can use fewer TDM mode configurations, which will affect the scheduling flexibility of the system.

Therefore, how to improve the flexibility of system scheduling in a scenario where a terminal device is dual-linked with two systems has become an urgent problem to be solved.

terminal devices

116 and 122 through the

forward links

116 and 124, respectively, the transmitting antennas of the network device 102 can use beamforming to improve the signal-to-noise ratio of the

forward links

116 and 124. In addition, compared with the way in which a network device sends signals to all of its terminal devices through a single antenna, when the network device 102 uses beamforming to send signals to

terminal devices

116 and 122 randomly dispersed in the relevant coverage area, the Mobile devices experience less interference.

At a given time, the network device 102, the terminal device 116, or the terminal device 122 may be a wireless communication transmitting apparatus and / or a wireless communication receiving apparatus. When transmitting data, the wireless communication transmitting device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (for example, generate, receive from another communication device, or save in a memory, etc.) a certain number of data bits to be transmitted to the wireless communication receiving device through a channel. Such data bits may be contained in a transport block (or transport blocks) of data, which may be segmented to generate multiple code blocks.

In addition, the communication system 100 may be a public land mobile network, a PLMN network, or a device-to-device (D2D) network, or a machine-to-machine (M2M) network, or other networks. Simplified schematic diagram, the network can also include other network equipment, not shown in Figure 1.

For ease of description, the following uses a terminal device as a UE as an example for detailed description.

In the communication system, the terminal equipment can be dual-linked with the two systems. In the following, one of the systems is an LTE system and the other is an NR system.

In the 5G communication system, a scenario in which the LTE system and the NR system are double-connected (DC) is introduced (ie, the EN-DC scenario). In the EN-DC scenario, the UE can communicate with network equipment of the LTE system on the one hand, and can also communicate with network equipment of the NR system on the other hand.

FIG. 2 is a schematic diagram of a UE performing communication in an EN-DC scenario. As shown in FIG. 2, when the UE 210 works in the EN-DC scenario, the UE 210 can communicate with the network device eNB220 of the LTE system and the network device gNB230 of the NR system at the same time.

Specifically, the UE 210 may be configured with at least two uplink radio frequency (RF) chains. One uplink radio link 240 may be used to send uplink signals to the eNB 220, and the other uplink radio link 250 may be used to send The gNB230 sends an uplink signal. The UE 210 may send uplink signals to the eNB 220 and the gNB 230 through two uplink radio frequency links (link 240 and link 250) at the same time.

However, due to the hardware design limitation of UE210, in some cases, UE210 cannot send uplink signals to eNB220 and gNB230 through two uplink radio frequency links (link 240, link 250) at the same time.

The following describes in detail a scenario in which the UE 210 cannot send uplink signals to the eNB 220 and the gNB 230 through two uplink radio frequency links at the same time.

As an example, when the UE 210 sends uplink signals to network devices (for example, eNB220, gNB230) through two uplink radio links at the same time, cross-modulation interference may occur. For example, the UE 210 may send an uplink signal of frequency f1 to the eNB 220 through the uplink radio frequency link 240, and at the same time, the UE 210 may send an uplink signal of frequency f2 to the gNB 230 through the uplink radio frequency link 250. Due to the poor linearity of the RF device (non-linearity of the RF device), the uplink signal with frequency f1 and the uplink signal with frequency f2 interact in the network to generate harmonic interference signals. The generated harmonic interference signal will interfere with the downlink signal received by the UE 210, thereby affecting the reception of the downlink signal of the UE 210. Therefore, the UE 210 cannot send uplink signals to the eNB 220 and the gNB 230 through two uplink radio frequency links (link 240 and link 250) at the same time.

As another example, when the UE 210 sends an uplink signal to a network device (for example, eNB220, gNB230) through two uplink radio links at the same time, the two communication systems cannot dynamically and flexibly allocate transmit power. For the EN-DC scenario, the UE 210 can have both a modem in the LTE system and a modem in the NR system. For example, in some design schemes, the modem of the LTE system and the modem of the NR system can be integrated in one chip (the modems of the two systems are coupled to each other), and the modem of the LTE system can share the uplink transmission power of the modem of the NR system. Allocation information, so that uplink transmission power of the LTE system can be dynamically and flexibly allocated, thereby avoiding exceeding the maximum transmission power of the UE 210. For another example, the modem of the LTE system and the modem of the NR system are in a design scheme of two independent modems (the modems of the two systems are not tightly coupled), because the modems of the LTE system cannot share the modem pair of the NR system The uplink transmission power allocation information makes it impossible to dynamically and flexibly allocate the uplink transmission power of the LTE system. Therefore, the UE 210 cannot send uplink signals to the eNB 220 and the gNB 230 through two uplink radio frequency links (link 240 and link 250) at the same time.

In summary, when the UE 210 works in the EN-DC scenario, the UE 210 can send uplink signals to the eNB 220 and the gNB 230 through the uplink radio frequency link at different times (time slots).

In the prior art, in order to ensure that uplink signals are sent to two systems (the eNB220 of the LTE system and the gNB230 of the NR system) at different times, when the 5G communication system is designed, time division multiplexing can be configured by uplink transmission of the LTE system. (time division multiplexing, TDM) mode. The uplink and downlink subframe configuration modes in the LTE system can be adopted, so that the UE 210 can send uplink signals to the eNB 220 and the gNB 230 in different time slots.

It should be understood that the TDM mode may be a mode in which different signals are transmitted in different periods of the same physical connection, and the time for transmitting information provided to the entire channel may be divided into several time slices (also referred to as time slots), and These time slots can be assigned to each source.

The following describes the TDM mode (pattern) of the LTE system in the EN-DC scenario in more detail with specific signaling:

subframeAssignment-r15 :: = SEQUENCE {sa0, sa1, sa2, sa3, sa4, sa5, sa6}

In the above signaling, the signaling "tdm-PatternConfig-r15 (TDM-mode configuration-r15)" can be used to indicate that the TDM mode configuration is performed through the r15 version in the standard, and the signaling "release NULL" can be used Indicates the release of resources occupied by invalid signaling. The signaling "setup SEQUENCE (equipment sequence)" can be used to indicate the serial number of the equipment, and the signaling "harq-offset-r15 (hybrid automatic repeat request-offset-r15)" can It is used to indicate the bias of hybrid automatic repeat request (HARQ) through the r15 version in the standard, and the signaling "subframe" Assignment-r15 :: = SEQUENCE {sa0, sa1, sa2, sa3, sa4, sa5 , Sa6} (subframe allocation-r15 = enum {sa0, sa1, sa2, sa3, sa4, sa5, sa6}) "can be used to indicate that the subframe allocation mode of the r15 version in the standard is {a0, sa1, sa2, sa3, sa4, sa5, sa6}.

It should be understood that in the TDM mode of the LTE system, the frame length is 10s, and it can be divided into 10 subframes with a length of 1s. The uplink and downlink data can be transmitted on different subframes within the same frame. The TDM of the LTE system can support different uplink and downlink time ratios, and the uplink and downlink time ratios can be adjusted according to the type of different services to meet the uplink and downlink asymmetric service requirements. In the same frame, the configuration of different uplink and downlink subframes can include the seven configurations shown in Table 1: sa0, sa1, sa2, sa3, sa4, sa5, sa6. For specific configurations of uplink and downlink subframes, see Table 1.

Table 1 uplink-downlink configurations

Among them, D in Table 1 can be used to represent a downlink subframe, and downlink data can be received on the downlink subframe; U can be used to represent an uplink subframe, which can be on the uplink subframe Sending uplink data; S can be used to indicate a special subframe, in which uplink data, downlink data, and uplink pilot data can be sent.

As can be seen from Table 1 above, in the EN-DC scenario, the uplink-downlink subframe ratio in the LTE system can be configured through the TDM mode, so that the UE 210 can send uplink signals to the eNB 220 and gNB 230 in different time slots.

However, in the prior art, only the TDM mode of the LTE system is configured. In order to enable the UE 210 to send uplink signals to the eNB 220 and gNB 230 in different time slots, the TDM mode of the LTE system that can be used will be relatively small, which will affect system scheduling. flexibility.

The following describes the configuration of sa2 in Table 1 as an example. If the TDM mode is set to sa2 in the LTE system (see Table 1, the uplink and downlink subframes in the sa2 configuration are configured as DSUDDDSUDD), when the UE 210 communicates with the LTE network device eNB22, the UE 210 can only be in subframe 2 And subframe 7 sends an uplink signal to the eNB 220 in the LTE system (subframe 2 and subframe 7 are uplink subframe U under the configuration sa2). In principle, when the TDM mode is sa2 configuration in the LTE system, the UE 210 can send uplink signals to the gNB230 in the NR system on the remaining subframes (for example, subframe 0, subframe 1, subframe 3, and subframe 4). , Subframe 5, Subframe 6, Subframe 8, Subframe 9).

However, for the NR system, in the actual working process of the system, the NR system also needs to prefabricate a TDM mode. When the frame structure (TDM mode) of the NR system and the frame structure (TDM mode) of the LTE system cooperate with each other, in order to enable the UE210 to send uplink signals to the eNB220 and gNB230 in different time slots, the TDM mode of the LTE system that can be used will be compared Less, which will affect the scheduling flexibility of the system.

The following uses the frame structure of DDDSUDDDSU in the NR system as an example, and describes it in detail with reference to FIG. 3.

FIG. 3 is a schematic diagram of a frame structure of an LTE system and a frame structure of an NR system being used together. In FIG. 3, the TDM mode of the LTE system is sa1, sa2, sa4, sa5 as an example.

Referring to FIG. 3, if the frame structure used in the NR system is DDDSUDDDSU, the TDM modes that cannot be used by the LTE system are sa1, sa4.

Specifically, taking the TDM mode of the LTE system as sa1 as an example, the UE 210 may send an uplink signal to the eNB 220 on subframe 8 (subframe 8 is an uplink subframe U in the frame structure of the LTE system). At the same time, the UE 210 may also Send an uplink signal to gNB230 on subframe 8 (subframe 8 is a special subframe S in the frame structure of the NR system). Since the UE 210 cannot send uplink signals to the eNB 220 and the gNB 230 at the same time, in an EN-DC scenario, the TDM mode that the LTE system cannot use is sa1.

Taking the TDM mode of the LTE system as sa4 as an example, the UE 210 can send an uplink signal to the eNB 220 in subframe 3 (subframe 3 is an uplink subframe U in the frame structure of the LTE system). At the same time, the UE 210 can also send an uplink signal in subframe 3 (Subframe 3 is a special subframe S in the frame structure of the NR system) sends an uplink signal to gNB230. Since the UE 210 cannot send uplink signals to the eNB 220 and the gNB 230 at the same time, in an EN-DC scenario, the TDM mode that the LTE system cannot use is sa4.

Therefore, in the prior art, in order to ensure that uplink signals are sent to each system at different times, the system (for example, the LTE system) can use fewer TDM mode configurations, which will affect the scheduling flexibility of the system.

The embodiments of the present application provide a method for uplink and downlink time resource configuration, which can increase the time resource configuration that the system can use in the scenario where the terminal device and the two systems are dual-linked, thereby improving the flexibility of system scheduling.

FIG. 4 is a schematic flowchart of a method for configuring uplink and downlink time resources according to an embodiment of the present application. The flowchart shown in FIG. 4 may include steps 410-430. Steps 410-430 are described in detail below.

Step 410: The terminal device receives first configuration information sent by the first network device, where the first configuration information indicates offset information of a first time resource configuration of the first system.

The first time resource configuration may also be biased in units of one symbol, or the first time resource configuration may be biased in units of multiple symbols including at least symbols. The first time resource configuration is offset in units of time, and may also be several combinations of the above-mentioned offset methods. The following will be described in combination with specific embodiments, which will not be described in detail here.

Step 430: The terminal device sends the second uplink information on the second time resource according to the second time resource configuration of the second system.

The terminal device may send the second uplink information on the second time resource according to the second time resource configuration of the second system.

In the embodiment of the present application, the second system is not specifically limited, and may be an LTE system, an NR system, a 3G system, a 4G system, or a PLMN network to be evolved in the future. As an example, the first system is an LTE system, and the second system may be an NR system. As another example, the first system is an NR system, and the first system is an LTE system. As another example, the first system is an LTE system, and the first system is an LTE system. As another example, the first system is an NR system, and the first system is an NR system.

In the following, the first system is an LTE system and the second system is an NR system as an example. In combination with specific signaling, the specific implementation of the uplink and downlink time resource allocation method mentioned in the embodiments of the present application will be described in more detail.

In the embodiment of the present application, in order to realize that the terminal device can send uplink information to the eNB of the LTE system and the gNB2 of the NR system on different time resources, a TDM mode can be configured for uplink transmission of the LTE system.

Specifically, the uplink transmission of the LTE system can be configured through signaling tdm-PatternConfig-r15 (TDM-mode configuration-r15, which can correspond to the first time resource configuration above).

In order to enable the terminal device to send uplink information to the LTE system eNB and the NR system gNB on different time resources, the flexibility of system scheduling can be improved, thereby increasing the TDM mode configuration that can be used in the LTE system. This embodiment of the present application An offset (offset, which can correspond to the offset information indicated in the first configuration information above) can be configured in the system, so that the TDM mode configuration of the LTE system after the offset can be compared with the TDM mode configuration of the NR system , It can be ensured that the terminal device will not send uplink information to the LTE system and the NR system at the same time in the same subframe (which may correspond to the time resource above).

Specifically, the terminal device may receive configuration information, and the configuration information may be used to indicate offset information of uplink and downlink time resource configuration of the LTE system.

It should be understood that the offset information of the uplink and downlink time resource configuration of the LTE system may be configured by the network device eNB in the LTE system to configure the terminal device, or may be configured by the network device gNB in the NR system to configure the terminal device. The terminal device may also be configured by a network device in another network, which is not specifically limited in this application.

The offset information of the uplink and downlink time resource configuration configured in the embodiment of the present application is described in more detail below with specific signaling.

In the embodiment of the present application, the offset information of the uplink and downlink time resource configuration may be used to offset the first time resource configuration in units of subframes, or may be used to offset the first time resource configuration in units of time slots. , Or the first time resource configuration may be offset in units of one symbol, or the first time resource configuration may be offset in units of multiple symbols including at least symbols, or the unit of time may be used to offset The first time resource configuration is biased, and may also be several combinations of the above-mentioned biasing methods.

In the embodiments of the present application, the first time resource configuration may be offset by combining any of the foregoing offset methods. As an example, the first time resource configuration may be performed with both an offset in units of a subframe and an offset in units of one symbol. As another example, the first time resource configuration may also perform an offset in units of a subframe and an offset in units of a plurality of symbols including at least symbols. As another example, the first time resource configuration may also perform both offset in units of subframes and offset in units of time.

The specific implementation manner of biasing the first time resource configuration by using a subframe as a unit in the embodiments of the present application is described in more detail below with specific signaling.

It should be understood that, in the above-mentioned signaling "subframe-offset-rxx INTEGER (0 ··· 9)", offsetting a subframe in a TDM mode configuration (time resource configuration) may be an offset in a unit of a subframe. Its offset range in units of subframes can be 0 to 9 subframes, which enables the terminal device to configure the TDM mode after the offset, and can send to the LTE system and the NR system in different time domains (time resources), respectively. Upstream information.

In the following, a specific implementation manner of biasing the first time resource configuration in units of symbols in the embodiments of the present application will be described in more detail in combination with specific signaling.

In the above signaling, the signaling "tdm-PatternConfig-r15 (TDM-mode configuration-r15)" can be used to indicate that the TDM mode configuration is performed through the r15 version in the standard, and the signaling "release NULL (release invalid)" can be used to Indicates the release of resources occupied by invalid signaling.

It should be understood that, in the above-mentioned signaling "symbol-offset-rxx INTEGER (0 ··· 139)", offsetting a subframe in a TDM mode configuration (time resource configuration) may be an offset in units of symbols. Its offset range in symbol units can be from 0 to 139 symbols, which can enable the terminal device to configure the TDM mode after the offset, and can send uplinks to the LTE system and the NR system in different time domains (time resources), respectively. information.

It should be understood that in the embodiment of the present application, the TDM mode configuration is biased in units of symbols. The TDM mode configuration may be biased in units of one symbol, or the TDM mode may be biased in units of multiple symbols including at least symbols. Configuration is biased.

The specific implementation of offsetting the first time resource configuration in units of time in the embodiments of the present application will be described in more detail below with specific signaling.

In the above signaling, the signaling "tdm-PatternConfig-r15 (TDM-mode configuration-r15)" can be used to indicate that the TDM mode configuration is performed through the r15 version in the standard, and the signaling "release NULL (release invalid)" can be used to Indicates the release of resources occupied by invalid signaling. The signaling "setup SEQUENCE (equipment sequence)" can be used to indicate the serial number of the equipment, and the signaling "harq-offset-r15 (hybrid automatic repeat request-offset-r15)" can It is used to indicate the HARQ offset in the standard r15 version. The signaling "subframe Assignment-r15" can be used to indicate the subframe allocation mode in the standard r15 version. The signal "time-offset-rxx ENUMERATED" (ms0.1, ms0.2 ... ms1, ms2 ...) (time-offset enumeration (ms0.1, ms0.2 ... ms1, ms2 ...)) '' can be used to indicate pairs The TDM mode configuration (corresponding to the first time resource configuration) in the signaling "tdm-PatternConfig-r15" is biased.

It should be understood that in the above-mentioned signaling "time-offset-rxx ENUMERATED (ms0.1, ms0.2 ··· ms1, ms2 ···)", it is possible to offset the subframes in the TDM mode configuration (time resource configuration). Is the offset in absolute time. Among them, ms0.1 represents 0.1ms, ms0.2 represents 0.2ms, ms1 represents 1ms, and ms2 represents 2ms. Biasing the TDM mode configuration with the absolute time as the offset unit can enable the terminal device to send uplink information to the LTE system and the NR system in different time domains (time resources) according to the TDM mode configuration after the offset.

In the following, a specific implementation manner of biasing the first time resource configuration by using a subframe as a unit and a symbol as a unit will be described in more detail in combination with specific signaling.

In the above signaling, the signaling "tdm-PatternConfig-r15 (TDM-mode configuration-r15)" can be used to indicate that the TDM mode configuration is performed through the r15 version in the standard, and the signaling "release NULL (release invalid)" can be used to Indicates the release of resources occupied by invalid signaling.

Offset is performed in units of subframes, and offset in units of one symbol. The terminal device can be configured to send uplink information to the LTE system and the NR system in different time domains (time resources) according to the TDM mode configuration after the offset.

In the following, a specific implementation manner of biasing the first time resource configuration by using a subframe as a unit and a time as a unit will be described in more detail in combination with specific signaling.

Signaling "subframe-offset-rxxINTEGER (0 ... 9) (subframe-offset-rxx enumeration (0 ... 9))" and signaling "time-offset-rxxENUMERATED (ms0.1, ms0.2 ·· ms1, ms2 ··· (time-offset enumeration (ms0.1, ms0.2 ·· ms1, ms2 ···)) "can be used to indicate that the signaling" tdm The TDM mode configuration (corresponding to the first time resource configuration) in "PatternConfig-r15" performs both offset in units of subframes and offset in units of absolute time. The terminal device can be configured to send uplink information to the LTE system and the NR system in different time domains (time resources) according to the TDM mode configuration after the offset.

It should be understood that, in the embodiment of the application, the above-mentioned several offset modes (an offset in units of subframes, an offset in units of one symbol, and an offset in units of multiple symbols including at least symbols may be arbitrarily combined with A plurality of combinations of offset in time) offset the first time resource configuration. For specific signaling, refer to the above signaling, which will not be repeated here.

The above-mentioned offset information that biases the time resource configuration may instruct the time resource configuration to be biased forward, may also indicate the time resource configuration to be biased forward, and may also instruct the time resource configuration to be cycled. Offset, this application does not specifically limit this.

It should be understood that taking the first system as an LTE system and the second system as an NR system as an example, the time resource configuration offset forward can be used to represent the frames in the TDM mode configuration in the LTE system but ahead of the NR system. some. The backward offset of the time resource configuration may be used to indicate a frame in a TDM mode configuration in an LTE system, but is delayed relative to the NR system.

The following describes a specific implementation manner of the uplink and downlink time resource allocation method mentioned in the embodiments of the present application in more detail with specific examples. It should be noted that the example of FIG. 5 is only for helping those skilled in the art to understand the embodiments of the present application, and is not intended to limit the embodiments of the application to the specific values or specific scenarios shown. Those skilled in the art can obviously make various equivalent modifications or changes according to the example shown in FIG. 5, and such modifications and changes also fall within the scope of the embodiments of the present application.

The following uses the first system as an LTE system and the second system as an NR system as an example for detailed description.

It should be understood that a variety of methods for offsetting time resource configuration (TDM mode configuration) are described above. In FIG. 5, the offset of time resource configuration in the unit of a subframe is described as an example.

Referring to FIG. 3 above, the TDM mode of the LTE system is sa1, sa2, sa4, sa5 as an example. After the analysis above, in order to realize that the terminal device can send uplink signals to the LTE system and the NR system on different subframes in Figure 3, if the frame structure used in the NR system is DDDSUDDDSU, then the TDM mode that the LTE system cannot use For sa1, sa4.

Taking sa1 as a TDM mode that cannot be used in the LTE system as an example, subframe 8 is an uplink subframe U in the frame structure of the LTE system, and a terminal device can send an uplink signal to the LTE system on the subframe 8. The subframe 8 is a special subframe S in the frame structure of the NR system, and the terminal device can send an uplink signal to the NR system on the subframe 8. Therefore, in order to achieve temporal interleaving between the terminal device and the uplink transmission of the LTE system and the uplink transmission of the NR system, the TDM mode that the LTE system cannot use is sa1. Similarly, in the sa1 mode of the LTE system, there is also a case where the terminal device can send uplink signals to the LTE system and the NR system at the same time. It can also be understood that if the LTE system is a special subframe S or an uplink subframe U on one subframe, the NR system cannot be S and U on the subframe.

In the embodiment of the present application, a bias is added to a TDM configuration mode (time resource configuration), so that the TDM mode configuration of the LTE system after the bias can be compared with the TDM mode configuration of the NR system, which can ensure that the terminal device will not be in the same child. The frame (which may correspond to the time resource described above) sends uplink information to the LTE system and the NR system at the same time. At the same time, the configuration of the TDM mode that can be used by the system can be increased in an offset manner, thereby enhancing the flexibility of system scheduling.

With reference to FIG. 5 below, the TDM modes that cannot be used in the LTE system analyzed above are sa1 and sa4 as an example. After detailed description of the offset of the TDM mode configuration (time resource configuration) in FIG. 5, the LTE system can be enabled. The use of TDM modes for sa1 and sa4 increases the TDM modes that can be used and enhances the flexibility of system scheduling.

Referring to FIG. 5, taking the TDM mode of the LTE system as sa1 as an example, the uplink and downlink subframe configuration of the LTE system is: DSUUDDSUUD, and the uplink and downlink subframe configuration of the NR system (without offset) is: DDDSUDDDSU. The TDM mode of the NR system may be offset in units of subframes. For example, the TDM mode of the NR system may be shifted forward by 4 subframes relative to the TDM mode of the NR system. The uplink and downlink subframes of the NR system after the offset are configured as: UDDDSUDDDS.

After the TDM mode of the NR system is biased, when the sa1 configuration mode of the LTE system is a special subframe S or an uplink subframe U on one subframe, the NR system is not a special subframe S and uplink on the subframe. Sub-frame U. The terminal device can send uplink signals to the LTE system and the NR system on different subframes according to the uplink and downlink subframe configuration of the LTE system and the TDM mode of the biased NR system.
