Description

Method, user equipment and system for sending sounding reference signal

Technical Field

The present invention relates to the field of electronic technologies, and in particular, to a sounding reference signal sending method, a user equipment, and a system.

Background

A Reference Signal (RS) is a known Signal provided by a transmitting end (e.g., a User Equipment (UE)) to a receiving end (e.g., a base station) for channel estimation or channel sounding. In a Long Term Evolution (LTE) system, reference signals are divided into uplink reference signals and downlink reference signals. Among them, sounding Reference Signal (SRS) is an uplink Reference Signal. The SRS is transmitted by the UE to the base station. And the base station performs uplink transmission resource allocation on the UE according to the SRS.

In a fifth Generation (5 th-Generation, 5G) New Radio (NR) system, a base station may configure a UE with multiple SRS resource sets. Each set of SRS resources may contain different SRS resources and ports. The maximum number of SRS resources that can be contained by one set of SRS resources, and the maximum number of SRS ports that can be contained by an SRS resource, depend on the capability of the UE. And the SRS port of each UE transmits SRS signals on the time-frequency resources configured by the base station. The base station receives the SRS signals at the corresponding time frequency resources. And the base station estimates the channel information between the SRS port and the base station according to the SRS signal.

However, the SRS signal transmitted from the UE to the base station has poor quality due to the limited processing capability and antenna capability of a single UE. Thus, the base station cannot accurately estimate the uplink channel, thereby affecting the communication of the uplink channel between the base station and the UE.

Disclosure of Invention

The embodiment of the application provides a method, a user equipment and a system for sending sounding reference signals, wherein the user equipment can enable another user equipment to assist in sending an SRS of the user equipment. In this way, the SRS of the user equipment received by the network equipment may be improved. Therefore, the network equipment can more accurately estimate the quality of the uplink channel between the network equipment and the user equipment according to the SRS of the user equipment.

In a first aspect, a system for transmitting sounding reference signals is provided, and the system may include: a first device, a second device and a network device; a first device and a second device are connected, the first device comprises M1 sounding reference signal SRS ports, the second device comprises M2 SRS ports, M1 and M2 are positive integers which are greater than or equal to 1, wherein,

the first device is configured to receive indication information of N1 sent by the second device, where N1 is the number of SRS ports, of the M2 SRS ports, that are available for sending the SRS of the first device; sending first configuration information to the second device, the first configuration information comprising: in the N1 SRS ports, the N2 SRS ports respectively correspond to SRS resources and SRS configuration parameters; respectively transmitting the SRS to the network equipment by using the M1 SRS ports; n2 is less than or equal to N1; the SRS configuration parameters are used for the second equipment to generate the SRS;

Thus, according to the system provided by the present application, in such a sounding signal transmission system, the second device may help the first device to transmit the SRS, and the network device may not be aware of the existence of the second device. The connection of the first device and the second device is transparent to the network device. The first device can be connected with the second device first, and then forms a system with the network device. The first device may have the second device assist the first device in transmitting SRS. In this way, the SRS of the first device received by the network device is the SRS transmitted by the first device and the SRS transmitted by the second device. The SRS resource and SRS of the SRS port of the second device are transmitted by the first device. Thus, the quality of the SRS of the first device received by the network device is improved.

With reference to the first aspect, in a possible implementation manner, the SRS resource and SRS corresponding to the port Pi are the same as the SRS resource and SRS corresponding to the port Pj; the ports Pi belong to the N2 SRS ports, and the ports Pj belong to the M1 SRS ports. For example, if there are three SRS ports A1, A2, and A3 in the first device, there are two SRS ports B1 and B2 in the second device for transmitting the SRS of the first device. Then the two SRS ports B1 and B2 in the second device may be respectively the same as the SRS resource and SRS resource corresponding to any one of the three SRS ports A1, A2 and A3.

With reference to the first aspect, in a possible implementation manner, N2= M1, the port Pi is an ith port of the N2 SRS ports, and the port Pj is a jth port of the M1 SRS ports. For example, if there are two SRS ports A1 and A2 in the first device, two SRS ports B1 and B2 in the second device may be used to transmit the SRS of the first device. Then, SRS port B1 may have the same SRS resource and SRS as SRS port A1. SRS port B2 may have the same SRS resource and SRS as SRS port A2.

Here, the SRS resources of different SRS ports may be the same or different. The SRS generated by different SRS ports according to the SRS resource may be the same or different. If the SRS resources of SRS port A1 and SRS port A2 are the same, the SRS of SRS port A1 and SRS port A2 are orthogonal to each other.

With reference to the first aspect, in a possible implementation manner, the first device is further configured to notify the network device that the number of currently available SRS ports is M3, where M3= M1+ N1; the network device is further configured to send second configuration information to the first device, where the second configuration information includes: the SRS resources corresponding to the N1 SRS ports respectively, and the SRS resources corresponding to the M1 ports respectively. That is, after the first device maps the SRS ports of the second device to the supplementary ports of the first device, the number of SRS ports of the first device is increased. The first device needs to report the number of SRS ports to the network device again. And the network equipment reallocates the SRS resources according to the number of the SRS ports reported by the first equipment.

I.e. the hot spot where the second device is connected to the first device. Alternatively, the first device and the second device may be connected via bluetooth. Alternatively, the first device and the second device may be connected through a Wi-Fi network transmitted by the same router. Alternatively, the first device and the second device are connected by other wireless short-range Communication technologies, such as Near Field Communication (NFC) technology.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation to the technical solution provided in the embodiment of the present application, and it can be known by a person of ordinary skill in the art that the technical solution provided in the embodiment of the present application is also applicable to similar technical problems with the evolution of the network architecture and the occurrence of a new service scenario.

The techniques described herein may be applied to include, but are not limited to: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) System, an advanced long term evolution (LTE-a) System, a LTE Frequency Division Duplex (FDD) System, a LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS) System, a world wide Interoperability for microwave Access (WiMAX) communication System, a next generation communication System (e.g., a fifth generation (UMTS-generation, 5G) communication System), a multi-generation UMTS communication System, a future-generation llc System, or a future-generation llc System.

The technical scheme provided by the application can be applied to uplink data (such as sounding reference signal) transmission. The data transmitting device may be a user equipment and the data receiving device may be a network device, such as a base station. In the following, the data sending device is a user equipment, and the data receiving device is a base station. In the embodiment of the present application, the first device may be a benefitting UE, the second device may be a cooperative UE, and the network device may be a base station.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating uplink channel data transmission between a single UE100 and a base station 200. An antenna 100a and an antenna 100b of the UE100 are exemplarily shown in fig. 1. The base station 200 includes an antenna 200a, an antenna 200b, an antenna 200c, and an antenna 200d. The UE100 establishes channels for transmitting data with respective antennas (antennas 100a to 100 d) of the base station through the

antennas

100a and 100b, respectively. When a single UE performs uplink channel data transmission with a base station, if the capabilities of the

antennas

100a and 100b in the UE100 are poor, the quality of the SRS signal transmitted by the UE100 to the base station 200 may also be affected.

In order to improve the signal quality of the SRS transmitted from the UE to the base station, an SRS transmission method is proposed in the prior art. Benefit the UE transmits SRS to the base station by means of the antenna capability of the cooperating UE. As shown in fig. 2, the benefit UE100, the cooperative UE300, and the base station 200 form a virtual Multiple-Input Multiple-Output (MIMO) system. The base station side knows the existence of the cooperative UE and configures SRS resources for the cooperative UE. This system amounts to an increase in the number of benefit UE transmit or receive antennas. And the beneficial UE and the cooperative UE transmit the SRS on the same time-frequency resource. Benefit UEs may transmit data to the base station via antennas assisting the UE. Thereby, the SRS signal quality of the beneficial UEs received by the base station 200 can be improved.

But in a scenario where inter-UE cooperation is transparent to the base station, i.e., the base station side does not know that the cooperative UE is assisting the beneficiary UE in data transmission. As shown in fig. 3, fig. 3 exemplarily shows a scenario in which inter-UE cooperation is transparent to a base station. The cooperation between the UE100 and the UE300 is transparent to the base station 200. The cooperative UE300 may utilize a Cell-Radio Network Temporary Identifier (C-RNTI) of the benefit UE100 to assist the benefit UE in transmitting data. The benefit UE does not inform the base station that the cooperative UE is assisting the benefit UE to send the SRS. Therefore, the base station does not perceive that the cooperative UE is assisting the benefited UE. When the cooperative UE transmits the SRS to the base station, the base station may only parse the SRS transmitted by the cooperative UE through communication with the base station. The base station may disregard the SRS transmitted by the cooperative UE assisted benefit UE. Therefore, the base station may lack the uplink channel information transmitted to the base station by the cooperative UE assisted benefit UE. If the base station only estimates according to the SRS signal of the beneficial UE, the base station cannot accurately estimate the uplink channel, which affects the uplink transmission resource allocation and communication performance.

Aiming at the problem that a base station can invisibly cooperate with UE to assist and benefit the SRS sent by the UE in the prior art, the embodiment of the application provides an SRS sending method, which comprises the following steps: the benefited UE acquires SRS port information of the cooperative UE; the beneficial UE maps the SRS port of the cooperative UE and performs SRS resource allocation on the SRS port of the cooperative UE; the beneficial UE sends the mapping mode and the SRS resource configuration information to the cooperative UE; the benefit UE and the cooperative UE transmit the SRS of the benefit UE on the configured resources.

It is to be understood that the virtual MIMO system as illustrated in fig. 3 provided in the present application may include one or more cooperative UEs 300. In the embodiment of the present application, a virtual MIMO system including one cooperative UE300 is described as an example.

With reference to fig. 3, a system provided in an embodiment of the present application will be described first. The system provided by the embodiment of the application comprises a first device, a second device and a network device; connecting a first device and a second device; the first device comprises M1 SRS ports, the second device comprises M2 SRS ports, M1 and M2 are positive integers which are larger than or equal to 1, wherein,

the first device is configured to receive indication information of N1 sent by the second device, where N1 is the number of SRS ports, which are available for sending SRSs of the first device, in M2 SRS ports, and send first configuration information to the second device, where the first configuration information includes: in the N1 SRS ports, the N2 SRS ports respectively correspond to SRS resources and SRS configuration parameters; the SRS configuration parameters are used for the second equipment to generate the SRS; respectively transmitting the SRS to the network equipment by using the M1 SRS ports; n2 is less than or equal to N1.

The second device is used for sending the indication information of the N1 to the first device; the first configuration information is also used for receiving first configuration information; and respectively transmitting the SRS on the corresponding SRS resources by using the N2 SRS ports.

In a possible implementation manner, the SRS resource and SRS corresponding to the port Pi are the same as the SRS resource and SRS corresponding to the port Pj; the ports Pi belong to the N2 SRS ports, and the ports Pj belong to the M1 SRS ports. For example, if there are three SRS ports A1, A2, and A3 in the first device, two SRS ports B1 and B2 in the second device may be used to transmit the SRS of the first device. Then the two SRS ports B1 and B2 in the second device may be respectively the same as the SRS resource and SRS resource corresponding to any one of the three SRS ports A1, A2 and A3.

In a possible implementation, N2= M1, the port Pi is an ith port of the N2 SRS ports, and the port Pj is a jth port of the M1 SRS ports. For example, if there are two SRS ports A1 and A2 in the first device, two SRS ports B1 and B2 in the second device may be used to transmit the SRS of the first device. Then, SRS port B1 may have the same SRS resource and SRS as SRS port A1. SRS port B2 may have the same SRS resources and SRS as SRS port A2. Here, SRS port B1 may have the same SRS resource as SRS port A2. SRS port B2 may have the same SRS resource as SRS port A1.

It can be understood that the network device is further configured to transmit the SRS resources and the SRS configuration parameters to the M1 SRS ports of the first device. And the first equipment generates the SRS according to the SRS configuration parameters. Here, SRS resources of different SRS ports may be the same or different. The SRS generated by different SRS ports according to the SRS resource may be the same or different. If the SRS resources of SRS port A1 and SRS port A2 are the same, the SRS of SRS port A1 and SRS port A2 are orthogonal to each other.

In a possible implementation manner, the first device is further configured to notify the network device that the number of currently available SRS ports is M3, and M3= M1+ N1; the network device is further configured to send second configuration information to the first device, where the second configuration information includes: the SRS resources corresponding to the N1 SRS ports respectively, and the SRS resources corresponding to the M1 ports respectively. That is, after the first device maps the SRS ports of the second device to the supplementary ports of the first device, the number of SRS ports of the first device is increased. The first device needs to report the number of SRS ports to the network device again. And the network equipment reallocates the SRS resources according to the number of the SRS ports reported by the first equipment.

It can be understood that the second configuration information further includes SRS configuration parameters corresponding to N1 SRS ports, and SRS configuration parameters corresponding to M1 SRS ports. Thus, the first device and the second device can generate the SRS according to the SRS configuration parameters.

In one possible implementation, the first device and the second device may be connected through a hotspot of the first device. I.e. the hotspot where the first device transmits over the second device connection. Alternatively, the first device and the second device may be connected via bluetooth. Alternatively, the first device and the second device may be connected through a Wi-Fi network transmitted by the same router.

Referring to fig. 5, a method for sending a sounding reference signal according to an embodiment of the present application specifically includes:

s101, beneficial UE is connected with cooperative UE, the first equipment comprises M1 SRS ports, the second equipment comprises M2 SRS ports, and both M1 and M2 are positive integers which are larger than or equal to 1.

Here, the procedure for connection between the benefit UE and the cooperative UE is a procedure for establishing a cooperative relationship between the benefit UE and the cooperative UE. The beneficiating UE may include M1 SRS ports, the cooperating UE may include M2 SRS ports, and both M1 and M2 are positive integers greater than or equal to 1.

Understandably, the benefit UE and the cooperative UE need to establish a cooperative relationship in advance, and the cooperative UE can assist the benefit UE to transmit the SRS. In the embodiment of the application, the beneficial UE directly establishes communication with the cooperative UE to establish a cooperative relationship. And in the process of establishing the cooperation relationship between the beneficial UE and the cooperative UE, the base station does not participate. That is, the beneficiary UE does not need to send a request to the base station to establish a cooperative relationship with the cooperative UE.

It can be understood that the number of SRS ports of the UE does not exceed 4 under the current protocol, i.e. M1 and M2 are greater than or equal to 1 and less than or equal to 4. When the maximum number of SRS ports of the UE in the future protocol changes, the maximum value of M1 and M2 in the embodiment of the present application also changes according to the maximum number specified by the protocol.

In one possible implementation, the beneficiary UE and the cooperating UE may connect through a hotspot of the beneficiary UE. I.e., hot spots where cooperating UEs connect to benefit from UE transmissions. Alternatively, the beneficiary UE and the cooperating UE may be connected via bluetooth. Or the beneficiary UE and the cooperative UE can be connected through a Wi-Fi network transmitted by the same router. Alternatively, the beneficiary UE and the cooperating UE are connected by other wireless short-range Communication technologies, such as Near Field Communication (NFC) technologies. It can be understood that the present application does not limit how the beneficiary UE and the cooperative UE are specifically connected.

When the beneficial UE and the cooperative UE can be connected through the hotspot of the beneficial UE, the beneficial UE opens the hotspot, and after the cooperative UE is connected with the hotspot of the beneficial UE, the beneficial UE and the cooperative UE establish a cooperative relationship. The cooperative UE may utilize a Cell-Radio Network Temporary Identifier (C-RNTI) of the benefit UE to assist the benefit UE in transceiving data. For how to open the hotspot by the benefited UE and how to connect the hotspot by the cooperative UE, reference may be specifically made to the description of opening the hotspot and connecting the hotspot in the prior art, which is not described herein again.

S102, receiving, by the benefit UE, the indication information of N1 sent by the cooperative UE, where N1 is the number of SRS ports that can be used for sending the SRS of the first device among the M2 SRS ports.

The beneficiating UE receives the indication information of the N1 sent by the cooperative UE, wherein the N1 is the number of SRS ports which can be used for sending the SRS of the beneficiating UE in the M2 SRS ports. It can be understood that it is assumed that the cooperative UE has 4 SRS ports, but 2 SRS ports in the cooperative UE are transmitting SRS of the cooperative UE to the base station. The cooperating UEs may only provide the benefit UEs with the port numbers and port numbers of the two idle SRS ports. Two idle SRSs in a cooperating UE may be used to transmit SRSs for a beneficiating UE.

Specifically, the benefit UE needs to acquire SRS port information of the cooperative UE, that is, the number of ports and port numbers that the cooperative UE can use to assist the benefit UE in transmitting SRS. The cooperative UE can actively report the SRS port information of the cooperative UE to the beneficial UE after being connected with the hotspot of the beneficial UE. Or, the beneficiary UE may send an instruction to the cooperative UE to obtain SRS port information of the cooperative UE. The benefit UEs need to map SRS ports of cooperating UEs. The beneficiary UE may map the SRS ports of the cooperating UEs to existing ports of the beneficiary UE or to supplemental ports of the beneficiary UE. Beneficial UEs have different mapping modes to the cooperative UEs, and SRS resource configurations of SRS ports in the cooperative UEs are also different. In particular, reference may be made to two different mapping manners of UEs to SRS ports of cooperating UEs in examples 1 and 2 below. Details of how the benefit UE maps the SRS ports of the cooperating UEs to the existing SRS ports of the benefit UE and how the SRS ports of the cooperating UEs configure SRS resources are described in example 1. Example 2 details how the benefit UEs map SRS ports of cooperating UEs to supplementary ports of the benefit UEs and how SRS resources are configured. This is not described in detail herein.

S103, the beneficial UE sends first configuration information to the cooperative UE, wherein the first configuration information comprises: in the N1 SRS ports, the N2 SRS ports respectively correspond to SRS resources and SRS configuration parameters; n2 is less than or equal to N1.

Here, the benefit UE needs to transmit the SRS resource and the SRS configuration parameter corresponding to the SRS port of the cooperative UE to the cooperative UE. And the cooperative UE generates the SRS according to the SRS configuration parameters. Each SRS port in the cooperative UE may transmit an SRS on a corresponding SRS resource.

In a possible implementation manner, the SRS resource and SRS corresponding to the port Pi are the same as the SRS resource and SRS corresponding to the port Pj; port Pi belongs to the N2 SRS ports and port Pj belongs to the M1 SRS ports. That is, any one of the ports available for transmitting SRS of the benefit UE in the cooperative UE may be mapped to any one of the SRS ports in the benefit UE. For example, when N2=3 and M1=2, three SRS ports B1, B2 and B3 in the cooperative UE are available for transmitting SRS of the benefit UE. There are two SRS ports A1 and A2 in the benefitting UE. Then SRS port B1 may be the same as the SRS resource of either SRS port A1 or SRS port A2. Similarly, SRS port B2 may be the same as SRS port A1 or SRS port A2 in SRS resource. SRS port B3 may be the same as SRS port A1 or SRS port A2 in SRS resource. Illustratively, three SRS resource configurations for cooperative UEs may be as shown in table 1. Table 1 exemplarily shows a case where SRS resources and SRS of each of 3 SRS ports of a cooperative UE may occur. Then the SRS resources and SRS for the 3 SRS ports of the final cooperative UE are shown in table 2. In table 2, SRS ports Aj (j =1, 2) correspond to SRS ports Bi (i =1, 2, 3), that is, SRS ports Bi and Aj have the same SRS resource and SRS. Both table 1 and table 2 take the example that the cooperative UE has three SRS ports B1, B2, and B3, and the benefited UE has two SRS ports A1 and A2. It can be understood that, the number of SRS ports of the beneficiating UE and the cooperating UE is not limited in the embodiments of the present application.

TABLE 1

TABLE 2

In a possible implementation manner, in case N2= M1, the port Pi is an i-th port of the N2 SRS ports, and the port Pj is a j-th port of the M1 SRS ports. That is, the SRS resource and SRS of the SRS port in the cooperating UE and the specific one of the beneficiating UEs are the same. For example, when N2= M1=2, i.e. there are B1, B2 two SRS ports available in the cooperating UEs for transmitting SRS for the benefit UE. The beneficiating UE has two SRS ports, A1 and A2. Then, there are two SRS resource and SRS configuration manners for the cooperative UE, that is, SRS port B1 and SRS port A1 have the same SRS resource and SRS, and SRS port B2 and SRS port A2 have the same SRS resource and SRS. Or the SRS resource and SRS of the SRS port B1 and the SRS port A2 are the same, and the SRS resource and SRS of the SRS port B2 and the SRS port A1 are the same. Referring to table 3, the SRS resources and SRS of 2 SRS ports of the final cooperative UE are as shown in table 3.

TABLE 3

In a possible implementation manner, the beneficiary UE sends the currently available SRS ports to the network device with a number of M3, where M3= M1+ N1; receiving, by the beneficiating UE, second configuration information sent by the network device, where the second configuration information includes: and the M3 SRS ports respectively correspond to the SRS resources. That is, SRS resources corresponding to N1 SRS ports, respectively, and SRS resources corresponding to M1 SRS ports, respectively; the beneficial UE sends first configuration information to the cooperative UE, wherein the first configuration information comprises: in the N1 SRS ports, the N2 SRS ports respectively correspond to SRS resources and SRS configuration parameters; n2 is less than or equal to the N1. Therefore, the number of SRS ports of the beneficial UE is the sum of the number of the SRS ports of the beneficial UE and the number of the SRS ports of the cooperative UE, and the SRS sending efficiency can be improved. Reference may be made to the description in example 2, which is not repeated here.

S104, the beneficial UE sends the SRS to the network equipment by using the M1 SRS ports; the network device is configured to determine, according to the received SRS, a quality of an uplink channel between the first device and the network device.

Here, the cooperating UEs transmit the SRS to the network device using N2 SRS ports. The benefit UE may transmit the SRS requiring cooperative UE assisted transmission to the cooperative UE. And then the benefit UE and the cooperative UE transmit the SRS on the configured SRS resource. Beneficial UEs have different SRS port mapping modes to cooperative UEs, and cooperative UEs have different SRS transmission modes. The benefited UE can enable the cooperative UE to transmit the SRS same as the benefited UE at the same time-frequency resource. Thus, the SRS received by the base station can see that the original SRS transmitted by the beneficial UE passes an equivalent information. The equivalent information is the superposition of the uplink channels of the benefit UE and the cooperative UE. This may result in a diversity gain and thus an enhancement of the SRS received by the base station. Here, specific reference may be made to the description in example 1, which will not be set forth herein first. The beneficiating UE may allow the cooperating UEs to transmit different data on the same time-frequency resource to obtain multiplexing gain. At this time, the SRS received by the base station is superimposed information of different SRSs transmitted by two UEs after passing through respective uplink channels. Here, specific reference may be made to the description in example 2, which will not be set forth herein first.

It can be understood that, before step S101, the network device, i.e. the base station, also transmits to the benefit UE the SRS resources of M1 SRS ports in the benefit UE. The network equipment can perform resource configuration of the periodic SRS and the aperiodic SRS for the UE. For the SRS resource configured as the period, the UE can periodically send the SRS according to the configured parameter; for the SRS resource configured as aperiodic, the UE needs to receive DCI signaling activation issued by the base station. And the UE can perform SRS transmission corresponding to the triggered SRS resource once every time the UE receives the DCI signaling triggering the aperiodic SRS resource once.

In this way, the ue may transmit the sounding reference signal by using the method for transmitting the sounding reference signal provided in the embodiment of the present application. When the antenna capability of the benefit UE is limited, the benefit UE may help the benefit UE to transmit the SRS by means of the antenna capability of the cooperative UE. In a scenario that a base station does not perceive cooperative UE, the method provided by the embodiment of the present application can enhance the quality of the SRS signal of the UE received by the base station to benefit from.

Further, when the benefit UE transmits the SRS to the base station in step S104, the cooperative UE uses N2 SRS ports to assist the benefit UE to transmit the SRS to the network device (e.g., the base station 200).

In order to facilitate clear understanding of a method for sending a sounding reference signal provided in an embodiment of the present application. A method for transmitting a sounding reference signal provided in an embodiment of the present application will be described in a specific scenario by using two exemplary examples, i.e., example 1 and example 2.

The following describes a specific scenario involved in example 1.

Example 1: SRS port mapping of cooperative UE to SRS port of benefitting UE

Fig. 6 illustrates a scenario in which the benefit UE100 maps SRS ports of the cooperating UE300 to SRS ports of the benefit UE 100. As shown in fig. 6, example 1 takes the beneficial UE100 having two SRS ports A1 and A2 and the cooperative UE300 having two SRS ports B1 and B2 as an example. The benefit UE100 maps the SRS port B1 of the cooperative UE300 to the SRS port A1 of the benefit UE 100. That is, the SRS port B1 of the cooperative UE300 may transmit the same data (e.g., SRS1 shown in fig. 6) on the same time-frequency resource as the SRS port A1 of the beneficiating UE 100. The benefit UE100 maps the SRS port B2 of the cooperating UE300 to the SRS port A2 of the benefit UE 100. That is, the SRS port B2 of the cooperative UE300 may transmit the same data (e.g., SRS2 shown in fig. 6) on the same time-frequency resource as the SRS port A2 of the beneficiating UE 100.

Fig. 7 shows an interaction diagram of a method for transmitting a sounding reference signal according to example 1 of the present application. The method for sending a sounding reference signal provided in example 1 specifically includes:

s201, the base station 200 transmits SRS resource configuration information to the benefit UE 100.

The base station 200 may transmit an SRS Resource and an SRS configuration parameter to the benefit UE100 through a Radio Resource Control (RRC) message. The UE may generate the SRS according to the SRS configuration parameters. Here, how the base station configures the SRS resource for the beneficial UE100 may refer to a process of configuring the SRS resource for the user equipment by the base station in the prior art, which is not described herein again. Similarly, how the UE generates the SRS according to the SRS configuration parameter may refer to descriptions in the prior art (e.g., protocols related to the SRS), which are not described herein again.

S202, the beneficial UE100 and the cooperative UE300 establish a cooperative relationship.

Step S202 may refer to the description of establishing the cooperative relationship between the benefited UE and the cooperative UE in step S101, which is not described herein again.

S203, the benefit UE100 acquires SRS port information of the cooperative UE300.

As shown in fig. 6, the coordinated UE300 has two SRS ports (i.e., SRS port B1 and SRS port B2) for example. The SRS port information acquired by the benefit UE100 to the cooperative UE300 may be port number 2, SRS port number of the SRS port B1, and port number of the port B2. The Port information in the cooperative UE can be obtained by inquiring the maxMnumberSRS-Port-Perresources field under the supported SRS-Resources. Of course, how to query the SRS port information is not limited in the embodiment of the present application.

S204, the benefit UE maps the SRS ports in the cooperative UE300 and the SRS ports in the benefit UE 100.

As shown in fig. 6, for example, the beneficiary UE100 has two SRS ports (SRS port A1 and SRS port A2), and the cooperative UE300 has two SRS ports (SRS port B1 and SRS port B2). Then the beneficiary UE100 may map the SRS port B1 of the cooperating UE300 to the SRS port A1 of the beneficiary UE 100. The beneficiary UE100 may map the SRS port B2 of the cooperating UE300 to the SRS port A2 of the beneficiary UE 100. In this way, SRS port B1 can multiplex SRS resources of SRS port A1. SRS port B2 may multiplex SRS resources of SRS port A2. It is to be appreciated that the beneficiary UE100 may also map the SRS port B1 of the cooperating UE300 to the SRS port A2 of the beneficiary UE 100. The beneficiary UE100 may map the SRS port B2 of the cooperating UE300 to the SRS port A1 of the beneficiary UE 100. The following description will take the mapping from SRS port B1 to SRS port A1 and from SRS port B2 to SRS port A2 as an example.

S205, the beneficiating UE100 sends the port mapping information and the SRS resource configuration information to the cooperating UE300.

The beneficiating UE100 sends the port mapping mode and the SRS resource configuration information to the cooperating UE300. In this way, cooperating UE300 knows that SRS port B1 is mapped to SRS port A1 and SRS port B2 is mapped to SRS port A2. According to the received SRS resource configuration information, the cooperative UE300 determines that the SRS resource of the SRS port B1 is the SRS resource configured by the SRS port A1, and determines that the SRS resource of the SRS port B2 is the SRS resource configured by the SRS port A2. And the cooperative UE may generate the SRS according to the SRS configuration parameters in the SRS resource configuration information.

S206, the benefit UE100 transmits the SRS to the base station 200.

The beneficiating UE100 transmits SRS1 to the base station 200 through SRS port A1 and SRS2 to the base station 200 through SRS port A2.

S207, the cooperative UE300 transmits the SRS of the benefit UE to the base station 200.

The SRS port B1 in the cooperative UE300 and the SRS port A1 of the UE100 transmit the same SRS, i.e., SRS1, to the base station 200 on the same SRS resource. The SRS port B2 in the cooperative UE300 and the SRS port A2 of the UE100 transmit the same SRS, i.e., SRS2, to the base station 200 on the same SRS resource.

Thus, the SRS received by the base station 200 from the benefit UE100 is a superposition of the SRS transmitted by the benefit UE100 and the SRS transmitted by the cooperating UE300. In this way, the SRS of the base station 200 received benefit UE100 is enhanced.

The following describes a specific scenario involved in example 2.

Example 2: port mapping of cooperative UE300 to supplemental ports of beneficiary UE100

Fig. 8 illustrates a scenario in which the benefit UE100 maps SRS ports of the cooperative UE300 to SRS ports that are complemented by the benefit UE 100. As shown in fig. 8, example 2 takes the benefit that UE100 has two ports A1 and A2, and cooperative UE300 has two ports B1 and B2 as an example. The beneficiary UE100 maps port B1 of the cooperating UE300 to a supplemental port A3 of the beneficiary UE 100. The beneficiary UE100 maps port B2 of the cooperative UE300 to the supplemental port A4 of the beneficiary UE 100. In this way, the SRS ports of the benefit UE100 are expanded from 2 ports (port A1 and port A2) to 4 ports (port A1-port A4).

Fig. 9 shows an interaction diagram of a sounding reference signal transmission method provided in example 2 of the present application. The method for sending the sounding reference signal provided in example 2 specifically includes:

s301, the base station 200 transmits SRS resource configuration information for the benefit UE 100.

The SRS resource configuration information includes SRS resources and SRS configuration parameters. The base station 200 may configure SRS resources for the benefit UE100 through a Radio Resource Control (RRC) message. Here, how the base station configures the SRS resource for the beneficial UE100 may refer to a process of configuring the SRS resource for the user equipment by the base station in the prior art, which is not described herein again. The beneficiary UE100 may generate the SRS according to the SRS configuration parameters. For the benefit of the UE100 to generate SRS according to the SRS configuration parameter, reference may be made to the description in the prior art (e.g., the SRS-related protocol), which is not described herein again.

S302, the beneficial UE100 and the cooperative UE300 establish a cooperative relationship.

Step S302 may refer to the description of establishing the cooperative relationship between the benefited UE and the cooperative UE in step S101, which is not described herein again.

S303, the beneficiating UE100 acquires SRS port information of the cooperative UE300.

As shown in fig. 8, the cooperative UE300 has two SRS ports (i.e., SRS port B1 and SRS port B2) for example. The SRS port information acquired by the benefit UE100 to the cooperative UE300 may be port number 2, SRS port number of the SRS port B1, and port number of the port B2. The Port information in the cooperative UE can be obtained by inquiring the maxMnumberSRS-Port-Perresources field under the supported SRS-Resources. Of course, how to query the SRS port information is not limited in the embodiments of the present application.

S304, the beneficiary UE100 maps the SRS ports in the cooperative UE300 to supplementary SRS ports in the beneficiary UE 100.

As shown in fig. 8, for example, the beneficiating UE100 has two SRS ports (SRS port A1 and SRS port A2), and the cooperating UE300 has two SRS ports (SRS port B1 and SRS port B2). The beneficiary UE100 maps the SRS port B1 of the cooperating UE300 to the supplemental port A3 of the beneficiary UE 100. The beneficiary UE100 maps the SRS port B2 of the cooperating UE300 to the supplemental port A4 of the beneficiary UE 100. In this way, the beneficiary UE100 expands from two ports to four ports. In step 301, the base station 200 configures SRS resources for only two ports of the beneficiating UE 100. Therefore, the number of ports of the benefit UE100 needs to be reported to the base station. For the beneficiary UE100, the SRS ports A3 and A4 are virtual ports, and actually data of the SRS ports A3 and A4 need to be transmitted to the base station 200 by the SRS ports B1 and B2 of the cooperative UE300. However, for the base station 200, the base station 200 may consider the beneficiary UE100 to have 4 SRS ports. The base station 200 is unaware of the presence of the cooperating UEs 300.

S305, the benefit UE100 reports SRS port information of the UE100 to the base station 200.

The benefit UE100 reports SRS port information of the UE100 to the base station 200. That is, the benefit UE100 transmits the number of SRS ports of the benefit UE100 to the base station 200 as 4 and the respective port numbers of the 4 SRS ports. The SRS ports of the benefit UE100 are extended by two (SRS ports A1-A2) to four (SRS ports A1-A4). Specifically, the beneficiating UE100 may change the information about the port configuration in the beneficiating UE100 to 4 and then transmit the information to the base station 200. For example, the beneficiary UE100 may modify the maxNumberbERS-Ports-PerResource field content to 4. Benefits the UE100 and sends the updated maxnumberber srs-Ports-resource information to the base station 200 through a capability information update request (which may be initiated through RRC or NAS signaling). After acquiring the new maxnumberber SRS-Ports-resource information, the base station 200 will re-configure the new SRS resource for the benefit UE 100.

S306, the base station 200 reconfigures SRS resources for the benefited UE 100.

The base station 200 may configure SRS resources for the benefit UE100 according to that the benefit UE100 has 4 SRS ports. For how to configure specifically, reference may be made to a base station in the prior art to configure SRS resources for a UE, which is not described herein again.

S307, the benefit UE100 sends the port mapping information and the SRS resource configuration information to the cooperative UE300.

The beneficiary UE100 provides the port mapping information and the SRS resource configuration information to the cooperative UE300. That is, the benefit UE100 notifies the cooperative UE300 that the SRS port B1 of the cooperative UE300 has been mapped to the SRS port A3 of the benefit UE100 and the SRS port B2 has been mapped to the SRS port A4 of the benefit UE 100. The cooperative UE300 may determine that the SRS resource of the SRS port B1 is the same as the SRS resource configured by the SRS port A3, and the SRS resource of the SRS port B2 is the same as the SRS resource configured by the SRS port A4. The cooperative UE300 generates the SRS according to the SRS configuration parameter in the SRS resource configuration information sent by the benefit UE 100.

S308, the benefit UE100 transmits the SRS to the base station 200.

The beneficiary UE100 transmits SRS1 to the base station 200 through the SRS port A1, and transmits SRS2 to the base station 200 through the SRS port A2.

S309, the cooperative UE300 transmits the SRS of the benefit UE received by the cooperative UE300 to the base station 200.

The cooperative UE300 transmits the SRS3 to the base station 200 through the SRS port B1. At this time, the base station 200 may consider the SRS3 to be transmitted through the SRS port A3 of the benefit UE 100. The cooperative UE300 transmits the SRS4 to the base station 200 through the SRS port B2. At this time, the base station 200 may consider that the SRS4 is transmitted through the SRS port A4 of the benefit UE 100.

In this way, the benefit UE maps the SRS ports of the cooperating UEs to supplemental ports of the benefit UE. The benefit UEs may utilize the cooperative UEs to transmit different SRSs to the base station on the same time-frequency resource. Thus, the spatial multiplexing gain can be obtained, and the transmission rate of the uplink channel is improved. The beneficial UEs can utilize the cooperation UEs to cooperatively transmit data, so that the base station can receive the data transmitted by the uplink channel more quickly.

Examples 1 and 2 of the embodiments of the present application are described by taking as an example that the number of SRS ports of the beneficiating UE100 and the cooperating UE300 is the same. The number of SRS ports of the benefit UE and the cooperative UE in the embodiment of the present application may also be different. It can be understood that, when the number of SRS ports of the benefit UE is smaller than or greater than the number of SRS ports of the cooperative UE, the sounding reference signal transmission method provided in the embodiment of the present application is still applicable. The following simple example describes a scenario where the number of SRS ports of the benefit UE and the cooperating UE is different.

In one possible implementation, the number of SRS ports of the benefit UE is greater than the number of SRS ports of the cooperating UE. For example, if the beneficiary UE has 2 SRS ports, the cooperative UE has 1 SRS port. The beneficiating UE may map 1 SRS port of the cooperating UE to one of 2 SRS ports of the beneficiating UE according to the method shown in example 1. Here, the specific implementation may refer to example 1, and details are not described here. The beneficiary UE may also map one SRS port of the cooperating UE to a supplementary SRS port of the beneficiary UE according to the method shown in example 2. Here, the specific implementation may refer to example 2, and details are not described here.

In another possible implementation, the number of SRS ports of the benefit UE is less than the number of SRS ports of the cooperating UE. For example, if the beneficiary UE has 2 SRS ports, the cooperative UE has 4 SRS ports. The beneficiating UE100 may select 2 SRS ports in the cooperating UEs to map to 2 ports in benefit according to the method shown in example 1. Here, the specific implementation may refer to example 1, and details are not described here. The beneficiary UE100 may also map 2, 3, or 4 of the 4 SRS ports in the cooperating UE to supplementary ports of the beneficiary UE100 according to the method in example 2. Here, the specific implementation may refer to example 2, and details are not described here. Alternatively, the beneficiating UE100 may also map the 2 SRS ports in the cooperating UE to the 2 SRS ports of the beneficiating UE according to the method in example 1. The beneficiary UE then maps the other two SRS ports of the cooperating UE to the supplementary SRS ports of the beneficiary UE according to the method shown in example 2. Here, the specific implementation may be combined with reference to example 1 and example 2, and is not described here again.
