[0002] In wireless communication, in order to enable a base station to obtain the channel quality of a terminal, the terminal usually needs to transmit a SRS (Sounding Reference Signal). The more antennas the terminal can participate in transmitting SRS, the more accurate the channel estimation, and the higher the rate that can be obtained.

[0003] In a 5th Generation Mobile Communication Technology (5G) communication system, a SRS round-robin mechanism is introduced, that is, in a multi-antenna case, SRS resources are transmitted by switching antennas.

[0004] In order to support more antenna round-robin, SRS resource sets are introduced in the 5G communication system, and according to the capability of a UE (User Equipment), some UEs can support multiple SRS resource sets.

[0005] When a UE supports multiple SRS resource sets, the multiple SRS resource sets can not be transmitted in the same slot. Since the terminal needs time to switch antenna ports, a certain guard interval (Gap) needs to be considered between SRS resource sets. SUMMARY

[0035] It can be understood that the description of the present disclosure focuses on the differences between various embodiments, and the same or similar parts can be referred to each other, and for brevity, will not be repeated.

[0036] Reference is made to Figure 1 which shows a structural schematic diagram of a wireless communication system provided by the embodiments of the present disclosure. As shown in Figure 1 , the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system can include a plurality of terminals 11 and a plurality of network devices 12.

[0037] The terminal 11 can be a device that provides voice and / or data connectivity to a user. The terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN), and the terminal 11 can be an Internet of Things UE, such as a sensor device, a mobile phone (also known as a "cellular" phone), and a computer with an Internet of Things UE, for example, which can be fixed, portable, pocket, hand-held, computer-embedded, or vehicle-mounted. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote UE, an access UE, a user device, a user agent, a user device, or a user equipment (UE). Alternatively, the terminal 11 can also be a device of an unmanned aerial vehicle. Alternatively, the terminal 11 can also be a vehicle-mounted device, which can be a vehicle-mounted computer with wireless communication function or a wireless communication device externally connected to the vehicle-mounted computer. Alternatively, the terminal 11 can also be a roadside device, which can be a street lamp, a signal lamp, or other roadside devices with wireless communication function, etc.

[0038] The network device 12 can be a device used for communication with the terminal in a wireless communication system. The wireless communication system can be a 4th generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system, or the wireless communication system can be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system can be a further next generation system of the 5G system. In the 5G system, the access network can be referred to as a NG-RAN (New Generation-Radio Access Network). Alternatively, the MTC system.

[0039] The network device 12 can be referred to as a wireless access network device, for example, including an access network device, such as a base station (e.g., an access point), which can refer to a device in the access network that communicates with the terminal via one or more cells over the air interface.

[0040] The network device 12 can be an evolved access device (eNB) used in a 4G system. Alternatively, the network device 12 can also be an access device (gNB) using a centralized and distributed architecture in a 5G system. When the network device 12 uses a centralized and distributed architecture, it usually includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a media access control (MAC) layer; and the distributed unit is provided with a physical (PHY) layer protocol stack. The specific implementation of the network device 12 is not limited in the embodiments of the present disclosure.

[0041] The network device 12 and the terminal 11 can establish a wireless connection through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on a fourth generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, such as a new air interface; or the wireless air interface can also be a wireless air interface based on a more next generation mobile communication network technology standard of 5G.

[0042] Optionally, the terminals 11 can also establish an E2E (End to End) or D2D (device to device) connection. For example, V2V (vehicle to vehicle) communication, V2I (vehicle to infrastructure) communication, and V2P (vehicle to pedestrian) communication in vehicle to everything (V2X) communication, and the like.

[0043] When the terminals establish a connection, if one or more terminals play the role of a base station in the communication between the terminals, the one or more terminals can also be regarded as the network device, and the other terminals can be regarded as the terminal 11. For example, in a vehicle networking scenario, a vehicle terminal A reports its capability information (such as antenna capability information) to another vehicle terminal B, and the vehicle terminal B controls the communication between the vehicle terminal A and the vehicle terminal B according to the capability information of the vehicle terminal A, that is, the vehicle terminal B plays the role of a head vehicle in the vehicle network. At this time, the vehicle terminal B can be regarded as the network device, and the vehicle terminal A can be regarded as the terminal 11.

[0044] Optionally, the wireless communication system can further include a network management device 13. A plurality of network devices are connected to the network management device 13 respectively. The network management device 13 can be a core network device in the wireless communication system, for example, the network management device 13 can be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device can also be other core network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS), etc. The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0045] In wireless communications, a network device can allocate one or more SRS resources to a UE for SRS transmission. The UE can be equipped with multiple antennas for transmitting signals or receiving signals (e.g., SRS or any other signals) to or from the network device. In the case that the UE supports multiple antennas, the SRS resources can be transmitted through antenna switching.

[0046] To support more antenna switching, SRS resource sets are introduced in 5G communication systems, and according to the capability of the UE, some UEs can support multiple SRS resource sets. When the UE supports multiple SRS resource sets, the multiple SRS resource sets can not be transmitted in the same time slot. Since the terminal needs time to switch the antenna port, a certain guard interval needs to be considered between SRSs. Since the position of the SRS resource set in the time slot can be arbitrary, it may lead to the time interval between two SRS resource sets being greater than the number of symbols occupied by the guard interval. In order to avoid resource waste, it has been agreed in the 3rd Generation Partnership Project (3GPP) specification that signals such as data signals or control signals can be transmitted in the time interval between SRS resource sets. But it depends on the configuration of the guard interval which antenna to send these signals.

[0047] Suppose that two SRS resource sets are configured for SRS transmission, the two SRS resource sets are denoted as SRS resource set #1 and SRS resource set #2 respectively, and each SRS resource set includes two SRS resources, which are denoted as SRS #1 and SRS #2 respectively.

[0048] There are various configuration schemes for the configuration of the guard interval, three typical schemes are taken as examples below.

[0049] As shown in Figure 2a , if the Gap between SRS resource sets is configured before SRS#1 of SRS resource set #2, the signal transmitted between SRS resource sets uses antenna 2, i.e. Ant#2 (diagonal shading in Figure 2a ).

[0050] As shown in Figure 2b , if the Gap between SRS resource sets is configured after SRS#2 of SRS resource set #1, the signal transmitted between SRS resource sets uses antenna 3, i.e. Ant#3 (diagonal shading in Figure 2b ).

[0051] As shown in Figure 2c , if the Gap between SRS resource sets is configured after SRS#2 of SRS resource set #1, and another Gap is configured before SRS#1 of SRS resource set #2, the signal transmitted between SRS resource sets can be switched to the optimal antenna, such as antenna 1, i.e. Ant#1 (diagonal shading in Figure 2c ).

[0052] Figure 2c The configuration scheme of the guard interval shown in Figure 2c can ensure that the signal transmitted between SRS resource sets is transmitted by the optimal antenna, which can improve the transmission efficiency of power and provide the maximum transmission power, but requires the configuration of an additional guard interval, resulting in the waste of some resources. Therefore, Figure 2a the configuration scheme of the guard interval shown in Figure 2b is suitable for cell edge user equipment (UE) and the case where the number of symbols between SRS resource sets is relatively large. Figure 2a The configuration scheme of the guard interval shown in Figure 2b is similar to the configuration scheme of the guard interval shown in , but relatively, since the performance of antenna 2 is better than that of antenna 3 in general cases,

[0053] the configuration scheme of the guard interval shown in Figure 3 is better than the configuration scheme of the guard interval shown in Figure 1 .

[0054] As shown in Figure 3 , the guard interval configuration method can include the following steps:

[0055] S12: transmitting, to the terminal, configuration information of a guard interval according to at least one of channel quality, transmit power information of the terminal, and a configuration request of the terminal; wherein the configuration information is used to determine a guard interval between SRS resource sets; wherein the configuration request is determined by the terminal according to the transmit power information of the terminal.

[0056] The guard interval configuration method is performed by a network device, which can be a base station, for example, a base station (or gNB) in a 5G system.

[0057] The configuration information of the guard interval at least indicates a time domain position of the guard interval.

[0058] The guard interval between two adjacent SRS resource sets is configured in a time interval between the two adjacent SRS resource sets. The guard interval occupies a number of time domain units less than or equal to a number of time domain units occupied by the time interval.

[0059] The configuration information of the guard interval includes at least one configuration parameter of the guard interval. The at least one parameter includes but is not limited to the position of the guard interval, the number of the guard interval, the time domain units to be occupied by the guard interval, etc.

[0060] The time domain unit can be a symbol or a mini-slot (Mini-slot). The symbol is, for example, an OFDM (Orthogonal Frequency Division Multiplexing) symbol. One guard interval can be configured to occupy 1 OFDM symbol or 2 consecutive OFDM symbols.

[0061] When the antenna switching of the terminal is used for signal transmission between the SRS resource sets, one or more symbols in the time interval between the two adjacent SRS resource sets and not occupied by the guard interval can be used for the signal transmission. The signal transmission is used to transmit data signals or control signals.

[0062] In some examples, the channel quality can be uplink channel quality. The network device can estimate the uplink channel quality of different frequency bands according to the SRS transmitted by the terminal.

[0063] In some examples, the uplink channel quality can be characterized using a quality parameter of the uplink channel, which can include at least one of a signal to interference plus noise ratio (SINR), a reference signal receiving power (RSRP), a received signal strength indicator (RSSI), a reference signal receiving quality (RSRQ), and the like.

[0064] In one embodiment, the method further comprises:

[0065] receiving the transmit power information of the terminal sent by the terminal.

[0066] The transmit power information of the terminal is sent by the terminal to the network device. For example, the terminal can send the transmit power information of the terminal to the network device through a medium access control control element (MAC CE).

[0067] In some other examples, the transmit power information of the terminal can be used to determine the transmit power of the terminal.

[0068] Exemplarily, the transmit power information can include at least one of:

[0069] maximum transmit power information of the terminal;

[0070] remaining transmit power information of the terminal;

[0071] a power headroom report (PHR) of the terminal.

[0072] Exemplarily, the power headroom report of the terminal is sent by the terminal to the network device. For example, the terminal can send the power headroom report of the terminal to the network device through a medium access control control element. The power headroom report includes the power headroom of the terminal, which is the difference between the maximum transmission power allowed by the terminal and the PUSCH (Physical Uplink Shared Channel) transmission power currently evaluated.

[0073] For example, the power headroom report can be configured in the terminal in two triggering modes, including: triggered by a pre-set periodic PHR timer period or triggered according to a path loss change event. After triggering the power headroom report, the terminal actively reports the power headroom report to the network device.

[0074] For another example, the power headroom report can be a power headroom report generated by the terminal in response to a power headroom report request instruction of the network device, and the power headroom report is reported to the network device. The power headroom report request instruction of the network device can be sent to the terminal by the network device when the terminal accesses.

[0075] In one embodiment, the method further comprises:

[0076] Receiving the configuration request sent by the terminal; wherein the configuration request is determined by the terminal according to the transmit power information of the terminal.

[0077] For example, the terminal can send the configuration request of the terminal to the network device through a medium access control layer control unit. In some examples, the configuration request of the terminal can be used to represent whether the transmit power of the terminal is greater than a preset transmit power threshold.

[0096] According to the channel quality and the configuration request, configuration information of the guard interval is sent to the terminal.

[0100] According to the channel quality and the configuration request, configuration information of the guard interval is sent to the terminal.

[0101] In the step S12, according to at least one of the channel quality, the transmission power information of the terminal and the configuration request of the terminal, the configuration information of the guard interval is sent to the terminal, which can include at least one of:

[0102] According to a comparison result between the channel quality and a preset quality threshold, the configuration information of the guard interval is sent to the terminal;

[0105] According to a comparison result between the transmission power of the terminal represented by the configuration request of the terminal and a preset transmission power threshold, the configuration information of the guard interval is sent to the terminal.

[0106] In step S12, the network device can send the configuration information of the guard interval to the terminal through RRC (Radio Resource Control) signaling or MAC layer signaling (for example, MAC-CE) and / or DCI (Downlink Control Information).

[0107] The network device can dynamically configure the guard interval between the SRS resource sets for the terminal, and compared with the network device allocating the same guard interval between the SRS resource sets for all terminals, the embodiment of the present disclosure can reduce the waste of network resources and / or the poor communication quality of the terminal caused by the unreasonable configuration of the guard interval, improve the communication quality of the terminal, and reduce the waste of network resources.

[0108] In one embodiment, the configuration information includes:

[0109] The first configuration information is used to indicate that one guard interval is configured after the end time of the first SRS resource set and before the start time of the second SRS resource set.

[0110] The second configuration information is different from the first configuration information.

[0111] The first configuration information is specifically used to indicate that the first and second guard intervals exist between the adjacent two SRS resource sets, and the first guard interval is adjacent to the last SRS resource of the first SRS resource set in the adjacent two SRS resource sets, and the second guard interval is adjacent to the first SRS resource of the second SRS resource set in the adjacent two SRS resource sets.

[0112] Referring to Figure 2c As shown in the figure, the first guard interval (Gap) configured between the SRS resource set #1 and the SRS resource set #2 is adjacent to the SRS #2 in the SRS resource set #1 and located after the SRS resource set #1; and the second guard interval (Gap) configured between the SRS resource set #1 and the SRS resource set #2 is adjacent to the SRS #1 in the SRS resource set #2 and located before the SRS resource set #2.

[0113] The number of time domain units occupied by the first guard interval and the number of time domain units occupied by the second guard interval between the two adjacent SRS resource sets can be the same. The time domain unit can be a symbol or a mini-slot.

[0114] For example, taking the time domain unit as a symbol for example, the first guard interval and the second guard interval can each occupy one symbol; that is, the first guard interval can be set at the first symbol after the end time of the first SRS resource set, and the second guard interval can be set at the last symbol before the start time of the second SRS resource set.

[0115] It can be understood that the number of time domain units occupied by the first guard interval and the number of time domain units occupied by the second guard interval can also be different, for example, the first guard interval occupies one symbol, and the second guard interval occupies two consecutive symbols.

[0116] In some examples, the number of time domain units occupied by the guard interval between the two adjacent SRS resource sets can be determined based on the SCS (sub-carrier space) used for SRS transmission.

[0117] The second configuration information is different from the first configuration information.

[0118] In one embodiment, the second configuration information is used to indicate that one guard interval is configured before the start time of the second SRS resource set or after the end time of the first SRS resource set in the two adjacent SRS resource sets.

[0119] In one example, the second configuration information indicates that there is only one guard interval between the two adjacent SRS resource sets, and the guard interval is adjacent to the last SRS resource of the first SRS resource set in the two adjacent SRS resource sets.

[0120] For example, the second configuration information indicates that one guard interval is configured at the first symbol after the end time of the first SRS resource set in the two adjacent SRS resource sets.

[0121] Referring to Figure 2b As shown in the figure, the guard interval (Gap) configured between SRS resource set #1 and SRS resource set #2 is adjacent to SRS #2 in SRS resource set #1 and is located after SRS resource set #1.

[0122] In another example, the second configuration information indicates that there is only one guard interval between the two adjacent SRS resource sets, and the guard interval is adjacent to the first SRS resource of the second SRS resource set of the two adjacent SRS resource sets.

[0123] For example, the second configuration information indicates that the last one or two OFDM symbols before the starting moment of the second SRS resource set of the two adjacent SRS resource sets set a guard interval.

[0124] Referring to Figure 2a As shown, one guard interval (Gap) configured between SRS resource set #1 and SRS resource set #2 is adjacent to SRS #1 in SRS resource set #2 and is located before SRS resource set #2.

[0125] In one embodiment, the step S12 of sending the configuration information of the guard interval to the terminal according to at least one of the channel quality, the transmission power information of the terminal, and the configuration request of the terminal can include:

[0126] According to at least one of the channel quality, the transmission power information of the terminal, and the configuration request of the terminal, and the number of time domain units between the SRS resource sets, the configuration information of the guard interval is sent to the terminal.

[0127] In one embodiment, the step of sending the configuration information of the guard interval to the terminal according to at least one of the channel quality, the transmission power information of the terminal, and the configuration request of the terminal, and the number of time domain units between the SRS resource sets includes at least one of the following modes:

[0128] Mode 1: The channel quality is less than a quality threshold, and the number of time domain units between the SRS resource sets is greater than a quantity threshold, and the first configuration information is sent to the terminal.

[0129] The network device can pre-configure the number of time domain units of the time interval between the SRS resource sets.

[0130] The number of time domain units of the time interval between the two adjacent SRS resource sets specifically refers to the number of symbols of the time interval between the two adjacent SRS resource sets.

[0131] The network device can pre-set the quality threshold of the channel quality and the quantity threshold of the time domain units, and compare the channel quality with the quality threshold, and compare the number of time domain units between the SRS resource sets with the quantity threshold.

[0132] When the channel quality is less than a quality threshold and a quantity of time domain units between the SRS resource sets is greater than a quantity threshold, the network device sends the first configuration information to the terminal.

[0133] In this embodiment, the channel quality being less than a quality threshold indicates that the channel quality is relatively poor, for example, the terminal is at the edge of cell coverage or in a weak signal environment; and the quantity of time domain units between the SRS resource sets being greater than a quantity threshold indicates that the time domain resources between the SRS resource sets are relatively more.

[0134] Therefore, the network device can send the first configuration information to the terminal to indicate that the terminal is configured with one guard interval after the end time of the first SRS resource set and before the start time of the second SRS resource set.

[0135] In this way, when the terminal performs antenna switching, the antenna used for signal transmission between the SRS resource sets is different from the antenna used for transmission of the last SRS resource in the first SRS resource set, and is also different from the antenna used for transmission of the first SRS resource in the second SRS resource set.

[0136] Therefore, in the case where the last SRS resource in the first SRS resource set is transmitted through antenna 2 and the first SRS resource in the second SRS resource set is transmitted through antenna 3, the network device can send the first configuration information to the terminal to enable the terminal to switch to the antenna 1 with the best performance for signal transmission between the SRS resource sets.

[0137] Method 2: When the channel quality is greater than or equal to the quality threshold, the network device sends the second configuration information to the terminal.

[0138] The network device can compare the channel quality with a pre-set quality threshold, and when the channel quality is greater than or equal to the quality threshold, the network device sends the second configuration information to the terminal.

[0139] In this embodiment, the channel quality being greater than or equal to a quality threshold indicates that the channel quality is relatively good, and the network device sends the second configuration information to the terminal to indicate that the terminal is configured with one guard interval before the start time of the second SRS resource set between the two adjacent SRS resource sets, so that the terminal uses the same antenna for transmission of the last SRS resource in the first SRS resource set and signal transmission between the SRS resource sets.

[0140] Thus, in the case that the last SRS resource in the first SRS resource set is transmitted through the antenna 2, the network device sends the second configuration information to the terminal, so that the terminal can use the antenna 2 for signal transmission between the first SRS resource set and the second SRS resource set.

[0141] Since the performance of the antenna 2 is only inferior to that of the antenna 1 among the multiple antennas of the terminal, the transmission signals between the SRS resource sets can be transmitted through a relatively better antenna. In addition, since the second configuration information indicates that the terminal configures only one guard interval between adjacent two SRS resource sets, the waste of time domain resources between the SRS resource sets can be reduced.

[0142] Option 3: The number of time domain units between the SRS resource sets is less than or equal to the number threshold, and the second configuration information is sent to the terminal.

[0143] The network device can compare the number of time domain units between the SRS resource sets with a preset number threshold, and when the number of time domain units between the SRS resource sets is less than or equal to the preset number threshold, the network device sends the second configuration information to the terminal.

[0144] In the embodiment, the number of time domain units between the SRS resource sets is less than or equal to the number threshold, which indicates that the time domain resources between the SRS resource sets are relatively less. The network device sends the second configuration information to the terminal, and indicates the terminal to configure one guard interval before the start time of the second SRS resource set or after the end time of the first SRS resource set among adjacent two SRS resource sets. In this way, only one guard interval is configured between adjacent two SRS resource sets, and the waste of time domain resources between the SRS resource sets can be reduced.

[0145] In addition, in the case that the second configuration information indicates the terminal to configure one guard interval before the start time of the second SRS resource set among adjacent two SRS resource sets, the terminal can use the same antenna for transmission of the last SRS resource in the first SRS resource set and signal transmission between the SRS resource sets.

[0146] In this way, in the case that the last SRS resource in the first SRS resource set is transmitted through the antenna 2, the terminal can transmit signals between the first SRS resource set and the second SRS resource set through the antenna 2. Since the performance of the antenna 2 is only inferior to that of the antenna 1 among the multiple antennas of the terminal, the signals between the SRS resource sets can be transmitted through the relatively optimal antenna.

[0147] In a fourth mode, the terminal has a transmission power greater than a preset power threshold, and the number of time domain units between the SRS resource sets is greater than a number threshold. The first configuration information is sent to the terminal.

[0148] The network device can preset the power threshold and the number threshold of the time domain units, and compare the transmission power of the terminal with the preset power threshold and compare the number of time domain units between the SRS resource sets with the number threshold.

[0149] When the transmission power of the terminal is greater than the preset power threshold and the number of time domain units between the SRS resource sets is greater than the number threshold, the network device sends the first configuration information to the terminal.

[0150] In this embodiment, the transmission power of the terminal is greater than the preset power threshold, indicating that the terminal is at the edge of the cell coverage or in a weak signal environment, and needs to use an antenna with better performance for signal transmission. In addition, the number of time domain units between the SRS resource sets is greater than the number threshold, indicating that the time domain resources between the SRS resource sets are relatively more.

[0151] Therefore, the network device can send the first configuration information to the terminal to indicate that the terminal is configured with one guard interval after the end time of the first SRS resource set and before the start time of the second SRS resource set.

[0152] In this way, in the case that the last SRS resource in the first SRS resource set is transmitted through the antenna 2 and the first SRS resource in the second SRS resource set is transmitted through the antenna 3, the terminal can switch to the antenna 1 with the best performance for signal transmission between the SRS resource sets.

[0153] In a fifth mode, the transmission power of the terminal is less than or equal to the preset power threshold. The second configuration information is sent to the terminal.

[0154] The network device can compare the transmission power of the terminal with the preset power threshold, and when the transmission power is less than or equal to the preset power threshold, the network device sends the second configuration information to the terminal.

[0155] In this embodiment, the terminal has a transmit power less than or equal to a preset power threshold, and the network device sends the second configuration information to the terminal, instructing the terminal to configure a guard interval before the start time of the second SRS resource set or after the end time of the first SRS resource set, so that the terminal only configures one guard interval between the two adjacent SRS resource sets, thereby reducing the waste of time domain resources between the SRS resource sets.

[0156] Option 6: The terminal has a power surplus less than or equal to a surplus threshold, and the number of time domain units between the SRS resource sets is greater than a number threshold, and the first configuration information is sent to the terminal.

[0157] The network device can compare the power surplus of the terminal with a preset surplus threshold, compare the transmit power of the terminal with a preset power threshold, and compare the number of time domain units between the SRS resource sets with the number threshold.

[0158] When the power surplus is less than or equal to the surplus threshold, and the number of time domain units between the SRS resource sets is greater than the number threshold, the network device sends the first configuration information to the terminal.

[0159] In this embodiment, the network device sends the first configuration information to the terminal, instructing the terminal to configure one guard interval after the end time of the first SRS resource set and before the start time of the second SRS resource set in the two adjacent SRS resource sets.

[0160] In this way, in the case that the last SRS resource in the first SRS resource set is transmitted through antenna 2, and the first SRS resource in the second SRS resource set is transmitted through antenna 3, the terminal can switch to the antenna 1 with the best performance to implement the signal transmission between the SRS resource sets.

[0161] Option 7: The terminal has a power surplus greater than the surplus threshold, and the second configuration information is sent to the terminal.

[0162] The network device can compare the power surplus of the terminal with a preset surplus threshold, and when the power surplus of the terminal is greater than the surplus threshold, the network device sends the second configuration information to the terminal.

[0163] In the embodiment, when the power headroom of the terminal is greater than the headroom threshold, the network device sends the second configuration information to the terminal, and instructs the terminal to configure a guard interval before the start time of the second SRS resource set or after the end time of the first SRS resource set, so that the terminal only configures one guard interval between the two adjacent SRS resource sets, thereby reducing the waste of time domain resources between the SRS resource sets.

[0164] In one embodiment, the sending of the configuration information of the guard interval to the terminal according to at least one of the channel quality, the transmit power information of the terminal, and the configuration request of the terminal, and the number of time domain units between the SRS resource sets comprises at least one of:

[0165] When the number of time domain units between the SRS resource sets is greater than the number threshold, the first configuration information is sent to the terminal based on the configuration request.

[0166] When the number of time domain units between the SRS resource sets is less than or equal to the number threshold, the second configuration information is sent to the terminal based on the configuration request.

[0167] In the embodiment, when the number of time domain units between the SRS resource sets is less than or equal to the number threshold, it indicates that the time domain resources between the SRS resource sets are relatively small, and the second configuration information can be sent to the terminal based on the configuration request of the terminal, so that the terminal only configures one guard interval between the two adjacent SRS resource sets, thereby reducing the waste of time domain resources between the SRS resource sets.

[0168] When the number of time domain units between the SRS resource sets is greater than the number threshold, it indicates that the time domain resources between the SRS resource sets are relatively large, and the first configuration information can be sent to the terminal based on the configuration request of the terminal, so that the terminal configures one guard interval after the end time of the first SRS resource set and before the start time of the second SRS resource set in the two adjacent SRS resource sets.

[0169] In this way, in the case that the last SRS resource in the first SRS resource set is transmitted through the antenna 2 and the first SRS resource in the second SRS resource set is transmitted through the antenna 3, the terminal can switch to the antenna 1 with the best performance to implement the signal transmission between the SRS resource sets, thereby ensuring the signal transmission between the SRS resource sets when the terminal is in the cell coverage edge or weak signal environment.

[0170] In one embodiment, the sending, to the terminal, the configuration information of the guard interval according to at least one of the channel quality, the transmission power information of the terminal and the configuration request of the terminal can comprise:

[0171] The sending, to the terminal, the configuration information of the guard interval not yet supplied to the terminal based on the configuration request according to the sending, to the terminal, the configuration information of the guard interval.

[0172] The configuration request is determined by the terminal according to the transmission power information of the terminal.

[0173] In some examples, the configuration request of the terminal can be used to represent whether the transmission power of the terminal is greater than a preset transmission power threshold.

[0174] Specifically, according to the sending, to the terminal, the configuration information of the guard interval, it can be determined that the terminal currently configures the guard interval between the SRS resource sets; according to the guard interval currently configured by the terminal between the SRS resource sets and the configuration request of the terminal, the sending, to the terminal, the configuration information of the guard interval not yet supplied to the terminal.

[0178] Specifically, according to the sending, to the terminal, the first configuration information of the guard interval, it can be determined that the number of the guard intervals currently configured by the terminal between the SRS resource sets is two, and the sending, to the terminal, the second configuration information of the guard interval not yet supplied to the terminal based on the configuration request, so as to instruct the terminal to configure one guard interval before the starting moment of the second SRS resource set adjacent to the first SRS resource set or after the ending moment of the first SRS resource set.

[0179] Specifically, according to the second configuration information of the guard interval that has been sent to the terminal, it can be determined that the terminal currently configures one number of guard intervals between the SRS resource sets; in the case that the number of time domain units between the SRS resource sets is greater than a preset number threshold, based on the configuration request, the first configuration information of the guard interval that has not been provided to the terminal is sent to the terminal to instruct the terminal to configure one guard interval after the end time of a first SRS resource set and before the start time of a second SRS resource set in the adjacent two SRS resource sets.

[0181] S22: receiving the configuration information of the guard interval sent by the network device according to at least one of the channel quality, the transmission power information of the terminal and the configuration request of the terminal; wherein the configuration information is used to determine the guard interval between the SRS resource sets; wherein the configuration request is determined by the terminal according to the transmission power information of the terminal.

[0182] Specifically, the terminal can receive the configuration information of the guard interval sent by the network device through RRC signaling, MAC layer signaling and / or DCI.

[0183] The guard interval configuration method provided by the embodiments of the present disclosure can make the terminal dynamically configure the guard interval between the SRS resource sets according to the configuration information of the guard interval sent by the network device, so as to reduce the waste of network resources and / or the phenomenon of poor communication quality of the terminal caused by unreasonable configuration of the guard interval, improve the communication quality of the terminal, and reduce the waste of network resources.

[0184] In one embodiment, the configuration information includes:

[0185] The first configuration information is used to instruct to configure one guard interval after the end time of a first SRS resource set and before the start time of a second SRS resource set in the adjacent two SRS resource sets;

[0186] The second configuration information, wherein the second configuration information is different from the first configuration information.

[0187] In one embodiment, the second configuration information is used to indicate that a guard interval is configured before a start time of a second SRS resource set of the two adjacent SRS resource sets or after an end time of a first SRS resource set of the two adjacent SRS resource sets.

[0188] In one embodiment, the receiving network device sends the configuration information of the guard interval according to at least one of channel quality, transmission power information of the terminal, and a configuration request of the terminal.

[0189] The receiving network device sends the configuration information of the guard interval according to at least one of channel quality, transmission power information of the terminal, and a configuration request of the terminal, and a number of time domain units between the SRS resource sets.

[0190] In one embodiment, as shown in Figure 5 based on Figure 4 , the method can further include:

[0191] S20: sending, to the network device, transmission power information of the terminal; wherein the transmission power information is used by the network device to determine configuration information of a guard interval sent to the terminal.

[0192] In one embodiment, as shown in Figure 6 based on Figure 4 , the method further includes:

[0193] S21: sending, to the network device, a configuration request determined according to the transmission power information of the terminal.

[0194] In some examples, the transmission power information of the terminal can be the transmission power of the terminal itself.

[0195] In other examples, the transmission power information of the terminal can be used to determine the transmission power of the terminal.

[0196] The transmission power information can include at least one of:

[0197] Maximum transmission power information of the terminal;

[0198] Remaining transmission power information of the terminal;

[0199] Power headroom report (PHR) of the terminal.

[0200] The terminal determines a comparison result between the transmission power of the terminal and a preset power threshold, and determines the configuration request sent to the network device according to the comparison result.

[0201] In one embodiment, the method further includes:

[0202] determining the configuration request according to the transmit power information of the terminal.

[0203] In some examples, the configuration request can be used to represent whether the transmit power of the terminal is greater than a preset transmit power threshold.

[0204] In one embodiment, the step S21 of transmitting the configuration request to the network device according to the transmit power information of the terminal includes at least one of the following ways:

[0205] Way 1: the terminal has received the first configuration information of the guard interval, and the transmit power of the terminal is less than or equal to a preset power threshold, the configuration request is transmitted to the network device.

[0206] When the terminal has received the first configuration information of the guard interval, it can be determined that the terminal currently configures two guard intervals between the SRS resource sets. When the transmit power of the terminal is less than or equal to a preset power threshold, the terminal transmits the configuration request to the network device to request the network device to configure only one guard interval between adjacent two SRS resource sets for the terminal, so as to reduce the waste of time domain resources between the SRS resource sets.

[0207] Way 2: the terminal has received the second configuration information of the guard interval, and the transmit power of the terminal is greater than the preset power threshold, the configuration request is transmitted to the network device.

[0208] When the terminal has received the second configuration information of the guard interval, it can be determined that the terminal currently configures one guard interval between the SRS resource sets.

[0209] When the transmit power of the terminal is greater than a preset power threshold, the terminal transmits the configuration request to the network device to request the network device to configure one guard interval after the end time of the first SRS resource set and before the start time of the second SRS resource set in adjacent two SRS resource sets for the terminal, so that the terminal can switch to the antenna with the best performance for signal transmission between the SRS resource sets, thereby ensuring the signal transmission between the SRS resource sets when the terminal is in the cell coverage edge or weak signal environment.

[0210] Way 3: the terminal has received the first configuration information of the guard interval, and the power margin of the terminal is greater than a margin threshold, the configuration request is transmitted to the network device.

[0211] The terminal has received the configuration information of the guard interval as the first configuration information, and it can be determined that the terminal currently configures two guard intervals between the SRS resource sets.

[0212] When the power headroom of the terminal is greater than the headroom threshold, the terminal sends the configuration request to the network device to request the network device to configure only one guard interval between adjacent two SRS resource sets for the terminal, so as to reduce the waste of time domain resources between the SRS resource sets.

[0213] Method 4: The received configuration information of the guard interval is the second configuration information, and the transmit power of the terminal is less than or equal to the headroom threshold, and the configuration request is sent to the network device.

[0214] The terminal has received the configuration information of the guard interval as the second configuration information, and it can be determined that the terminal currently configures one guard interval between the SRS resource sets.

[0215] When the transmit power of the terminal is less than or equal to the headroom threshold, the terminal sends the configuration request to the network device to request the network device to configure one guard interval after the end time of the first SRS resource set and before the start time of the second SRS resource set in adjacent two SRS resource sets for the terminal, so that the terminal can switch to the optimal antenna for signal transmission between the SRS resource sets, and thus ensure the signal transmission between the SRS resource sets when the terminal is in the cell coverage edge or weak signal environment.

[0216] Next, taking a network device as a base station as an example, the protection interval configuration method provided by the present disclosure is described in combination with specific embodiments.
