Generally, the conventional Communication system supports a limited number of connections and is easy to implement, however, with the development of Communication technology, the mobile Communication system will support not only conventional Communication but also, for example, device-to-Device (D2D) Communication, machine-to-Machine (M2M) Communication, machine Type Communication (MTC), and Vehicle-to-Vehicle (V2V) Communication, and the embodiments of the present application can also be applied to these Communication systems. Optionally, the communication system in the embodiment of the present application may be applied to a Carrier Aggregation (CA) scenario, may also be applied to a Dual Connectivity (DC) scenario, and may also be applied to an independent (SA) networking scenario.

A terminal 110 in the embodiments of the present application may refer to a user equipment, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user device. The terminal may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a relay device, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved Public Land Mobile Network (PLMN), and the like, which are not limited in this embodiment. As shown in fig. 1B, the terminal 110 in the terminal according to the embodiment of the present disclosure may include one or more of the following components: the device comprises a processor 110, a memory 120 and an input-output device 130, wherein the processor 110 is respectively connected with the memory 120 and the input-output device 130 in a communication mode.

The network device 120 in this embodiment may be a device for communicating with a terminal, where the network device may be an evolved NodeB (eNB or eNodeB) in an LTE system, may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or the network device may be a relay device, an access point, an in-vehicle device, a wearable device, a network device in a future 5G network or a network device in a future evolved PLMN network, one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, or may also be a network node forming a gNB or a transmission point, such as a baseband unit (BBU) or a Distributed Unit (DU), and the embodiment of the present invention is not limited.

In some deployments, the gNB may include a Centralized Unit (CU) and a DU. The gNB may also include an Active Antenna Unit (AAU). The CU implements part of the function of the gNB and the DU implements part of the function of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implements functions of a Radio Resource Control (RRC) layer and a Packet Data Convergence Protocol (PDCP) layer.

Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as the RRC layer signaling, may also be considered to be transmitted by the DU or by the DU + AAU under this architecture. It is to be understood that the network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, the CU may be divided into network devices in an access network (RAN), or may be divided into network devices in a Core Network (CN), which is not limited in this application.

The application layer comprises applications such as a browser, an address list, word processing software, instant messaging software and the like. Furthermore, the embodiment of the present application does not particularly limit the specific structure of the execution main body of the method provided by the embodiment of the present application, as long as the communication can be performed according to the method provided by the embodiment of the present application by running the program recorded with the code of the method provided by the embodiment of the present application, for example, the execution main body of the method provided by the embodiment of the present application may be a terminal, or a functional module in the terminal that can call the program and execute the program.

At present, when configuring an SRS-resource set, usage of the SRS resource set may be configured, and when receiving a signal requesting to transmit the SRS resource set, a terminal may determine the SRS resource set corresponding to the signal, and may further determine usage configuration corresponding to the SRS resource set, so as to transmit the SRS resource.

Specifically, the terminal may determine, according to the received information requesting to transmit the SRS, a plurality of SRS resource sets, where the plurality of SRS resource sets may include 1 or more SRS resource sets configured by different usages, and each SRS resource set may include one or more SRS resources. At present, when a terminal determines multiple SRS resource sets configured by different usages, the terminal sends the SRS resource configured by each different usages, but in practical application, sometimes it is not necessary to send the SRS resource configured by each different usages, but at present, it is not supported to dynamically select the SRS resource configured by a specific usage in the SRS resource sets configured by multiple different usages, so that the sending of the SRS resource is not flexible enough, and resource waste and device power consumption waste may be caused.

In view of the above problem, an embodiment of the present application provides a transmission method, which is described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a schematic flow chart of a transmission method according to an embodiment of the present application, and as shown in fig. 2, the transmission method includes:

step 201, the network device sends downlink control information DCI.

Step 202, the terminal receives the DCI sent by the network device.

Wherein, the Downlink Control Information (DCI) is used to indicate a target usage configuration and candidate SRS resources.

Step 203, the terminal acquires the target SRS resource from the candidate SRS resource.

Wherein the usage configuration corresponding to the target SRS resource includes the target usage configuration.

Specifically, the terminal may determine the candidate SRS resource according to the DCI, and further determine a usage configuration corresponding to the candidate SRS resource, and for any one of the candidate SRS resources, if the corresponding usage configuration includes a target usage configuration, the terminal may determine it as the target SRS resource; if the corresponding usage configuration does not include the target usage configuration, the terminal will not determine the corresponding usage configuration as the target SRS resource and will not transmit the target SRS resource subsequently.

And step 204, the terminal sends the target SRS resource.

The terminal may transmit the target SRS resource by: and the terminal transmits the SRS signal on the target SRS resource.

In a specific implementation, if one target SRS resource corresponds to multiple usage configurations, where the multiple usage configurations include both a target usage configuration and other usage configurations that are not the target usage configuration, when the terminal transmits the target SRS resource, a behavior corresponding to the target usage configuration of the target SRS resource is triggered, and a behavior corresponding to the other usage configurations is not triggered.

In a specific implementation, each usage configuration may include at least one of the following: codebook configuration, non-codebook noncodbook configuration, antenna polling antenna configuration, beam management beamManagement configuration.

In the embodiment of the application, the DCI is used to indicate the target usage configuration and the candidate SRS resources, and after receiving the DCI, the terminal acquires the usage configuration including the target SRS resources of the target usage configuration from the candidate SRS resources, and then transmits the target SRS resources. Therefore, in the embodiment of the present application, the terminal may determine and transmit the target SRS resource configured by the specific use according to the DCI dynamics, which is beneficial to improving the flexibility of SRS resource transmission.

In one possible example, the DCI includes an SRS request field to indicate the candidate SRS resources.

In specific implementation, the terminal may determine trigger state information corresponding to a codepoint value according to the codepoint value of an SRS request field, that is, an SRS request field, and further determine an SRS resource associated with the trigger state information as a candidate SRS resource.

As can be seen, in this example, the DCI includes the SRS request field for indicating the candidate SRS resource, which is beneficial to accurately determining the candidate SRS resource.

In one possible example, the code point value corresponding to the SRS request field is a first preset value, the DCI further includes a channel state information CSI request field and an uplink shared channel UL-SCH indication field, the code point value corresponding to the CSI request field is a second preset value, and the code point value corresponding to the UL-SCH indication field is a third preset value.

And the second preset value and the third preset value can both be 0. The first preset value is not 0.

In a specific implementation, after the terminal receives the DCI information and before the target SRS resource is acquired from the candidate SRS resource, the terminal may determine code point values corresponding to a CSI request field, an UL-SCH indication field, and an SRS request field in the DCI. When the code point values of the three fields accord with a preset value, the terminal executes the steps of determining the target SRS resource from the candidate SRS resources and transmitting the target SRS resource; if the code point value of any one of the three fields does not accord with the preset value, the terminal does not execute the subsequent step of acquiring the target SRS resource from the candidate SRS resource, but transmits each candidate SRS resource.

In this example, in the case that code point values corresponding to the CSI request field, the UL-SCH indication field, and the SRS request field in the DCI meet preset values, the terminal determines and transmits the target SRS resource from the candidate SRS resources, which is beneficial to improving the accuracy of determining the SRS resource transmission policy by the terminal.

In one possible example, the DCI includes first information used to indicate the target usage configuration, where the first information includes P parameters, P is a positive integer, and each of the P parameters corresponds to at least one usage configuration; a first parameter of the P parameters corresponds to a first usage configuration, and a parameter value of the first parameter is used for indicating whether the first usage configuration is a target usage configuration.

In a specific implementation, the use configuration corresponding to each parameter may be different, and the terminal may determine whether the use configuration corresponding to the parameter is the target use configuration according to a parameter value of any one of the parameters, and further may determine the target use configuration from 1 or more different use configurations.

In a specific implementation, each of the P parameters may correspond to only one usage configuration, or each of the P parameters may correspond to multiple usage configurations, or the P parameters may include both a parameter corresponding to one usage configuration and a parameter corresponding to multiple usage configurations; specifically, the setting may be performed according to the needs of the actual situation, for example, when the P value is small, the number of usage configurations corresponding to one parameter may be appropriately increased, and when the P value is large, each parameter may correspond to only one usage configuration.

As can be seen, in this example, the parameter value of each of the P parameters of the DCI is used to indicate whether the corresponding use configuration is the target use configuration, and the terminal may determine the target use configuration according to the specific parameter value, which is beneficial to improving the accuracy of determining the target use configuration.

In one possible example, if the parameter value of the first parameter is a first parameter value, the first usage configuration is a target usage configuration; otherwise, the first usage configuration is not the target usage configuration.

In specific implementation, the value of the first parameter value corresponding to each of the P parameters may be the same, or the values of the first parameters corresponding to different parameters may also be different, and the specific value of the first parameter value corresponding to each parameter may be set according to the actual application requirement, which is not specifically limited here.

For example, the P parameters include parameter 1, parameter 2, and parameter 3, for example. The first parameter value corresponding to each parameter may be 0, that is, the value of the first parameter value is 0 no matter which parameter of the parameters 1, 2 and 3 is the first parameter. At this time, if the parameter value of the parameter 1 is 0, the use configuration corresponding to the parameter 1 is the target use configuration, and if the parameter value of the parameter 1 is not 0 (for example, the parameter value of the parameter 1 is 1), the use configuration corresponding to the parameter 1 is not the target use configuration, and the parameters 2 and 3 are the same;

or, when the first parameter is parameter 1, the value of the first parameter value may be 0, and when the first parameter is parameter 2 or parameter 3, the value of the first parameter may be 1. For the parameter 1 or the parameter 3, if the parameter value is 0, the corresponding usage configuration is the target usage configuration, and if the parameter value is 1, the corresponding usage configuration is not the target usage configuration; for the parameter 2, if the parameter value is 0, the corresponding usage configuration is not the target usage configuration, and if the parameter value is 1, the corresponding usage configuration is the target usage configuration.

As can be seen, in this example, when the parameter value of the first parameter is the first parameter value, the first usage configuration is the target usage configuration, and whether the usage configuration corresponding to the parameter is the target usage configuration is indicated by the parameter value of one parameter, which is beneficial to improving the accuracy of determining the target usage configuration.

In one possible example, if the parameter value of the first parameter is a second parameter value, a second usage configuration in the first usage configuration is a target usage configuration; and if the parameter value of the first parameter is a third parameter value, configuring a third use configuration in the first use configuration as a target use configuration.

In specific implementation, the second parameter value and the third parameter value can be set according to the requirements of practical application, and the second parameter value and the third parameter value can be set to any two different values. For example, the second parameter value is 0, and the third parameter value is 1; alternatively, the second parameter value is 1, and the third parameter value is 0, which is not limited herein.

If the parameter value of the first parameter is the second parameter value, the third usage configuration may be a usage configuration other than the second usage configuration, and when the second usage configuration is the target usage configuration, the third usage configuration may also be represented as not the target usage configuration; if the parameter value of the first parameter is the third parameter value, the third usage configuration is characterized, and meanwhile, the second usage configuration is also characterized to be not the target usage configuration. That is, whether each first usage configuration is a target usage configuration may be indicated at the same time by a parameter value of one parameter.

As can be seen, in this example, different parameter values of the first parameter are used to indicate that different usage configurations in the first usage configuration are configured to the target usage configuration, which is beneficial to improving the accuracy of determining the target usage configuration.

In one possible example, the first information includes Hybrid automatic repeat request Process Number HARQ (Hybrid automatic repeat request) Process Number field information, where P is equal to 4, the P parameters are in one-to-one correspondence with four usage configurations, and the usage configurations corresponding to each of the P parameters are different.

The four usage configurations may be: codebook configuration, non-codebook noncodbook configuration, antenna polling antenna configuration, beam management beamManagement configuration.

The P parameters may be 4 bits of information in the HARQ Process number field: x1, X2, X3 and X4. The 4-bit information may correspond to four usage configurations one to one, and the usage configurations corresponding to each bit of information are different.

For example, X1 corresponds to a codebook configuration, X2 corresponds to a nocodebook configuration, X3 corresponds to an antennaSwitching configuration, X4 corresponds to a beamManagement configuration, an SRS resource a exists in the candidate SRS resources, a use configuration of the SRS resource a is a codebook configuration, and the first parameter value is fixed to 0. If the value of X1 is 0, it indicates that codebook configuration is target usage configuration, SRS resource a is target SRS resource, and the terminal will transmit the SRS resource a, otherwise, if the value of X1 is not 0, for example, the value of X is 1, codebook configuration is not target usage configuration, SRS resource a is not target SRS resource, and the terminal will not transmit the SRS resource a. Similarly, if the usage configuration of the SRS resource B in the candidate SRS resources is a nonCodebook configuration, if the value of X2 is 0, the terminal may transmit the SRS resource B, and if the value of X2 is 1, the terminal may not transmit the SRS resource B.

It should be noted that each of the P parameters specifically corresponds to which of the four usage configurations, and this is not limited herein. That is, it is not specifically limited which configuration among the 4-bit information in the HARQ Process number field corresponds to the codebook configuration, the nocodebook configuration, the antennaSwitching configuration, and the beamManagement configuration.

For another example, X1 corresponds to the nonodebook configuration, X2 corresponds to the Codebook configuration, X3 corresponds to the antennaSwitching configuration, and X4 corresponds to the beamManagement configuration. Wherein, the first parameter values corresponding to X1, X3, and X4 are all 0, the first parameter value corresponding to X2 is 1, and the candidate SRS resource includes: the usage is configured as SRS resource C configured by Codebook, the usage is configured as SRS resource D configured by non-Codebook, the usage is configured as SRS resource E configured by anti switching, and the usage is configured as SRS resource F configured by beacon management. If the values of X1, X2, X3, and X4 are sequentially 0, 1, and 0, the terminal will transmit SRS resource C and SRS resource F, and if the values of X1, X2, X3, and X4 are sequentially 1, and 1, the terminal will only transmit SRS resource D.

As can be seen, in this example, the first information includes information of a HARQ Process number field of an existing field in DCI, and four parameters in the field respectively indicate whether four usage configurations are target usage configurations, which is beneficial to improving flexibility of SRS resource transmission.

In one possible example, the first information includes HARQ Process number field information, P is equal to 3, and the P parameters include a second parameter, a third parameter, and a fourth parameter; the second parameter corresponds to a fourth use configuration or a fifth use configuration in the four use configurations; the third parameter corresponds to a sixth use configuration of the four use configurations; the fourth parameter corresponds to a seventh usage configuration of the four usage configurations.

The terminal may determine, according to the high-level configuration information, for example, the transmission configuration parameter txConfig, whether the second parameter corresponds to the fourth usage configuration or the fifth usage configuration.

The four usage configurations may be: codebook configuration, nocodebook configuration, antennaSwitching configuration, and beamManagement configuration.

In a specific implementation, the fourth use configuration may be any one of a codebook configuration and a nocodebook configuration, and the fifth use configuration is another one of the codebook configuration and the nocodebook configuration except the fourth use configuration. For example, if the fourth usage is configured as Codebook configuration, the fifth usage is configured as non-Codebook configuration, or if the fourth usage is configured as non-Codebook configuration, the fifth usage is configured as Codebook configuration.

The sixth usage configuration may be an antennaSwitching configuration or a beamManagement configuration, and correspondingly, the seventh usage configuration is a beamManagement configuration or an antennaSwitching configuration.

The P parameters may be HARQ Process number field 4-bit information: any three bits of information in X1, X2, X3, and X4 may be, for example, X1, X2, and X3, or may be X1, X2, and X4, which is not limited herein.

In a specific implementation, each of the P parameters specifically corresponds to which bit information of the above-mentioned arbitrary three bit information, and is not specifically limited here. For example, when any three bits of information are X1, X2, and X3, X1, X2, and X3 may be a second parameter, a third parameter, and a fourth parameter in sequence, or X1 is the third parameter, X2 is the second parameter, and X3 is the fourth parameter.

For example, the fourth use is configured as a codebook configuration, the fifth use is configured as a non-codebook configuration, the sixth use is configured as an antnnaswitching configuration, the seventh use is configured as a beamManagement configuration, the second parameter is X1, the third parameter is X2, and the fourth parameter is X3. If the first parameter value is fixed to 0, the terminal determines that the second parameter corresponds to a fourth use configuration according to the high-level configuration information, if the value of X1 is 0, if an SRS resource G configured by the use configuration to codebook configuration exists in the candidate SRS resource, the SRS resource G is determined as a target SRS resource, otherwise (for example, if the value of X1 is 1), the SRS resource G is not determined as the target SRS resource; and if the terminal determines that the second parameter corresponds to the fifth usage configuration according to the high-level configuration information, and when the value of X1 is 0, determining the SRS resource H configured by the usage configuration in the candidate SRS resources as the target SRS resource.

As can be seen, in this example, the first information includes HARQ Process number field information of an existing field in DCI, and the target usage configuration is indicated by parameter values of three parameters in the existing field, which is beneficial to improving flexibility of SRS resource transmission.

In one possible example, the first information includes Antenna port Antenna ports field information, P is equal to 2, and the P parameters include: a fifth parameter and a sixth parameter; the fifth parameter corresponds to an eighth use configuration of the four use configurations; the sixth parameter corresponds to three usage configurations of the four usage configurations except for the eighth usage configuration.

In a specific implementation, the parameter value of the sixth parameter may be used for characterizing, and all three usage configurations outside the eighth usage configuration are target usage configurations, or none of the three usage configurations is a target usage configuration.

Wherein, the four usage configurations may be: codebook configuration, nocodebook configuration, antennaSwitching configuration, and beamManagement configuration.

In a specific implementation, the eighth use configuration may be a beamManagement configuration.

The P parameters may be 2 bits of information in the Antenna ports field: x1 and X2.

In a specific implementation, the Antenna ports field may include multiple pieces of bit information, and X1 and X2 may be any two pieces of bit information in the multiple pieces of bit information of the Antenna ports field; that is, the fifth parameter may be any one bit information in the Antenna ports field, and the sixth parameter may be any one bit information in the Antenna ports field except for the bit information corresponding to the fifth parameter.

For example, if the fifth parameter is X1 (any bit information in the Antenna ports field), the sixth parameter is X2 (any bit information except X1 in the Antenna ports field), and the eighth use configuration is a beacon management configuration example, if the parameter value of the first parameter is fixed to 0, then X1 is 0, and if there is an SRS resource I configured by use configuration to beacon management in the candidate SRS resources, then it is determined as the target SRS resource. When X2 is 0, if an SRS resource J exists in the candidate SRS resources, determining the SRS resource J as a target SRS resource, where a usage configuration of the SRS resource J may include any one or more of: codebook configuration, nocodebook configuration, antennaSwitching configuration.

It should be noted that, in other embodiments, the parameter value of the sixth parameter may also be used to characterize: in the three usage configurations other than the eighth usage configuration, the terminal may determine, according to other configuration information, whether any one of the three usage configurations is the target usage configuration, where the any one of the three usage configurations is specifically the one of the three usage configurations. The eighth use configuration may also be any one of a codebook configuration, a nocodebook configuration, an antennaSwitching configuration, and a beamManagement configuration, and is not specifically limited herein.

As can be seen, in this example, the first information includes information of antenna port antenna ports of an existing field in DCI, and the target usage configuration is indicated by parameter values of two parameters in the existing field, which is beneficial to improving flexibility of SRS resource transmission.

In one possible example, the first information includes Antenna ports field information, P equals 2; the P parameters are in one-to-one correspondence with the two use configurations, and the use configurations corresponding to each parameter in the P parameters are different.

The two usage configurations may be any two of the following: codebook configuration, non-codebook nonCodebook configuration, antenna polling antenna switching configuration, beam management beamManagement configuration.

The P parameters can be 2 bits of information in the Antenna ports field: x1 and X2.

In a specific implementation, the Antenna ports field may include a plurality of bits of information, and X1 and X2 may be any two bits of information among the plurality of bits of information of the Antenna ports field. That is, when P is equal to 2, P parameters may correspond to any two bits of information in the Antenna ports field one-to-one.

Each of the P parameters specifically corresponds to which of the two usage configurations, and is not limited herein. That is, it is not specifically limited which configuration among any 2-bit information in the Antenna ports field, each bit information specifically corresponds to a codebook configuration, a non-codebook configuration, an antennaSwitching configuration, and a beamManagement configuration.

For example, by taking X1 corresponding to codebook configuration and X2 field corresponding to antennaSwitching configuration as an example, if the first parameter value is fixed to 0, then X1 is 0 and X2 is 1, and if one SRS resource corresponds to one usage configuration, then in the candidate SRS resources, when there is an SRS resource K whose usage configuration is codebook configuration, then the SRS resource K is determined as a target SRS resource; if one SRS resource corresponds to two different usage configurations, in the candidate SRS resources, if there is an SRS resource Z with a usage configuration of codebook configuration and antennaSwitching configuration, the SRS resource Z is taken as a target SRS resource, but when the terminal transmits the SRS resource Z, only a behavior corresponding to codebook configuration is triggered.

As can be seen, in this example, the first information includes Antenna port Antenna ports field information in an existing field in the DCI, and the target usage configuration is indicated by parameter values of two parameters in the existing field, which is beneficial to improving flexibility of SRS resource transmission.

Each of the P parameters specifically corresponds to which of the two usage configurations, which is not limited herein. That is, it does not specifically define which configuration among the 2-bit information in the Antenna ports field, each bit information specifically corresponds to the codebook configuration, the nocodebook configuration, the antennaSwitching configuration, and the beamManagement configuration.

For example, taking X1 corresponding to the codebook configuration and X2 field corresponding to the antennaSwitching configuration as an example, if the first parameter value is fixed to 0, then X1 is 0 and X2 is 1, in the candidate SRS resources, if there is an SRS resource Y whose usage configuration is the codebook configuration and the antennaSwitching configuration, then the SRS resource Y is taken as the target SRS resource, but when the terminal transmits the SRS resource Y, only the behavior corresponding to the codebook configuration is triggered. When the SRS resource W configured by the use as codebook, antennaSwitching, beamManagement or non-codebook exists in the candidate SRS resource, determining the SRS resource W as a target SRS resource;

In one possible example, the first information includes Antenna ports field information, P equals 1, and the P parameters include a seventh parameter; the seventh parameter corresponds to four use configurations; the third usage configuration comprises a ninth usage configuration of the four usage configurations; the second usage configuration comprises: three of the four usage configurations other than the ninth usage configuration.

The P parameters can be 1-bit information in the Antenna ports field: and (4) X1.

In a specific implementation, the ninth usage configuration may be an antennaSwitching configuration. That is, the third usage is configured as an antennaSwitching configuration, the second usage is configured as a codebook configuration, a non-codebook configuration, and an antennaSwitching configuration, and when the parameter value of the seventh parameter (i.e., X1) is the third parameter value, the usage is configured such that the candidate SRS resource configured by the antennaSwitching configuration is the target SRS resource, and when the parameter of the seventh parameter (i.e., X1) is the second parameter value, the usage is configured such that the candidate SRS resource configured by the antennaSwitching configuration, the non-codebook configuration, or the antennaSwitching configuration is the target SRS resource.

The values of the second parameter value and the third parameter value may be set as needed, for example, the second parameter may be 0, and the third parameter value may be 1.

In other embodiments, the ninth usage configuration may also be any one of a codebook configuration, a non-codebook configuration, and an antennaSwitching configuration, which is not specifically limited herein.
