The technical scheme shown in the application is described in detail through specific embodiments. It should be noted that the following embodiments may exist alone or in combination with each other, and for the same or similar content, the description will not be repeated in different embodiments.

Fig. 2 is a flow chart of a resource allocation method according to an embodiment of the present application. Referring to fig. 2, the method may include:

s201, the network equipment acquires the number of transmitting antenna ports and the number of receiving antenna ports of the terminal equipment.

The execution body of the embodiment of the application may be a network device, or may be a resource allocation device disposed in the network device. Alternatively, the resource allocation device may be implemented by software, or may be implemented by a combination of software and hardware.

The transmitting antenna port of the terminal device is used for transmitting signals, and the receiving antenna port is used for receiving signals. For example, the terminal device may transmit data to the base station through a transmit antenna port, and the terminal device may receive data transmitted by the base station to the terminal device through a receive antenna port. Alternatively, one antenna port may correspond to a plurality of physical antenna ports.

Alternatively, the same antenna port in the terminal device may receive signals, or may transmit signals. For example, the terminal device includes 8 antenna ports, each antenna port can receive signals, the number of the receiving antenna ports of the terminal device is 8, among the 8 antenna ports of the terminal device, 6 antenna ports can also be used for transmitting signals, and the number of the receiving antenna ports of the terminal device is 6, but the terminal device is substantially provided with only 8 antenna ports.

The number of transmit antenna ports in the terminal device is less than or equal to the number of receive antenna ports. For example, if the number of receiving antenna ports in the terminal device is 8, the number of receiving antenna ports in the terminal device is an integer less than or equal to 8. Optionally, in the practical application process, in order to facilitate signal transmission, the number of receiving antenna ports installed in the terminal device may be an even number greater than 1, and the number of transmitting antenna ports installed in the terminal device may be 1 or an even number greater than 1. For example, the number of receiving antenna ports of the terminal device may be 6, 8, 10, 12, etc., and the number of transmitting antenna ports of the terminal device may be 1, or may be 2, 4, 6, 8, 10, etc.

The terminal device may send antenna port information of the terminal device to the network device. The antenna port information includes the number of transmitting antenna ports and the number of receiving antenna ports of the terminal equipment. For example, if the terminal device includes 8 receiving antenna ports and 6 transmitting antenna ports, the antenna port information sent by the terminal device to the base station is: 6 transmit antenna ports, 8 receive antenna ports. For example, the terminal device may send the number of transmit antenna ports and the number of receive antenna ports of the terminal device to the network device.

Optionally, the network device may determine the number of transmit antenna ports and the number of receive antenna ports of the terminal device according to the identifier of the terminal device. For example, the terminal device may send the ID of the terminal device to the network device, where the network device determines the number of transmitting antenna ports and the number of receiving antenna ports of the terminal device according to preset device information and the ID of the terminal device, where the device information includes at least one ID of the terminal device and the number of transmitting antenna ports and the number of receiving antenna ports corresponding to the ID of each terminal device. For example, the device information may be as shown in table 1:

TABLE 1

It should be noted that table 1 is only exemplary schematic device information, and is not limited to device information.

For example, if the identifier of the terminal device received by the base station is identifier 1, the base station may determine that the number of transmitting antenna ports of the terminal device is 6, and the number of receiving antenna ports is 6; if the identifier of the terminal equipment received by the base station is identifier 2, the base station can determine that the number of transmitting antenna ports of the terminal equipment is 8, and the number of receiving antenna ports is 8; if the identifier of the terminal device received by the base station is identifier 3, the base station may determine that the number of transmitting antenna ports of the terminal device is 6, and the number of receiving antenna ports is 8.

S202, the network equipment determines antenna port configuration and SRS resource information of the terminal equipment according to the number of transmitting antenna ports and the number of receiving antenna ports.

The antenna port is configured as antenna port combination information configured by the network device for the terminal device. For example, if the antenna ports used by the terminal device are 8 transmitting antenna ports and 8 receiving antenna ports, and the antenna ports that the terminal device receives the network device to send are configured as 6 transmitting antenna ports and 8 receiving antenna ports, the terminal device switches the configuration of the 8 transmitting antenna ports to the configuration of the 6 transmitting antenna ports.

The SRS resource information includes the number of SRS resource sets (SRS resource sets) and the number of SRS resources (SRS resources) in each SRS resource set. Wherein, the SRS resource set may include at least one SRS resource. For example, one SRS resource set may include 1 SRS resource, or may include a plurality of SRS resources. The SRS resource is a resource of the terminal device transmitting the SRS to the network device. For example, the terminal device may send an SRS to the base station according to SRS resources configured by the base station for the terminal device, so that the base station detects communication quality of the uplink channel.

Next, a procedure for the network device to determine the antenna port configuration of the terminal device will be described.

The number of transmitting antenna ports of the terminal equipment is M, and the number of receiving antenna ports of the terminal equipment is N. Wherein M is an integer greater than or equal to 1, N is an integer greater than or equal to 6, and M is less than or equal to N. For example, if the number of receiving antenna ports of the terminal device is 6, the number of transmitting antenna ports of the terminal device may be 1, 2, 4, 6; if the number of receiving antenna ports of the terminal device is 8, the number of transmitting antenna ports of the terminal device may be 1, 2, 4, 6, 8.

The antenna port configuration includes a first number of transmit antenna ports configured for the terminal device and a second number of receive antenna ports configured for the terminal device. Wherein the first number is less than or equal to M, the second number is less than or equal to N, and the first number is less than or equal to the second number. For example, if the number M of transmitting antenna ports of the terminal device is 6 and the number N of receiving antenna ports is 8, the first number of transmitting antenna ports configured by the network device for the terminal device may be 1, 2, 4, 6, and the second number of receiving antenna ports configured by the network device for the terminal device may be 6 or 8 (the number of receiving antenna ports is greater than or equal to 6).

Optionally, when the network device configures the antenna ports for the terminal device, the network device may combine any one of the antenna ports to determine the antenna port configuration of the terminal device. For example, if the number of transmitting antenna ports and the number of receiving antenna ports of the terminal device received by the network device are 8, the network device may determine 6 transmitting antenna ports and 8 receiving antenna ports as antenna port configurations of the terminal device and send the antenna port configurations to the terminal device, where the terminal device uses the 6 transmitting antenna ports and the 8 receiving antenna ports to perform communication, and the network device may also determine 8 transmitting antenna ports and 8 receiving antenna ports as antenna port configurations of the terminal device and send the antenna port configurations to the terminal device, where the terminal device uses the 8 transmitting antenna ports and the 8 receiving antenna ports to perform communication.

Next, a procedure of configuring an antenna port for a terminal device by a network device will be described with reference to fig. 3.

Fig. 3 is a schematic diagram of a process for determining an antenna port configuration according to an embodiment of the present application. Please refer to fig. 3, which includes a terminal device and a network device. The terminal device may send antenna port information of the terminal device to the network device. For example, the terminal device may send the number of transmit antenna ports to the network device: 8, number of receiving antenna ports: 8 antenna port information. When the network device receives the antenna port information of the terminal device, the network device can configure the number of used transmitting antenna ports and the number of used receiving antenna ports for the terminal device according to the antenna port information of the terminal device, and send the antenna port configuration to the terminal device. For example, the network device determines, according to 8 transmit antenna ports and 8 receive antenna ports, that the antenna ports of the terminal device are configured as the number of transmit antenna ports: 6, number of receiving antenna ports: 8, and transmitting the antenna port configuration to the terminal device. In principle, the base station may configure the terminal with any number of transmitting antenna ports reported by the terminal device or any number of receiving antenna ports reported by the terminal device.

Next, a procedure of allocating SRS resources to terminal devices by the network device will be described.

The network device may determine SRS resource information of the terminal device according to the following possible implementation manner: and configuring the number of SRS resource sets and the number of SRS resources in each resource combination for the terminal equipment according to the first number and the second number.

Optionally, the network device may determine, according to the first number and the second number, a total number of SRS resources required for the antenna port configuration used by the terminal device, and further determine SRS resource information according to the total number of SRS resources. For example, when the first number and the second number are the same, determining that the total number of SRS resources of the terminal device is 1; and when the first quantity and the second quantity are different, determining that the total SRS resources of the terminal equipment are the ratio of the second quantity to the first quantity to be rounded upwards. For example, if the first number of transmitting antenna ports used by the terminal device is 6 and the second number of receiving antenna ports is 6, the network device determines that the total SRS resources of the terminal device are 1; if the first number of the transmitting antenna ports used by the terminal equipment is 8 and the second number of the receiving antenna ports is 8, the network equipment determines that the total SRS resource number of the terminal equipment is 1; if the first number of the transmitting antenna ports used by the terminal equipment is 4 and the second number of the receiving antenna ports is 8, the network equipment determines that the total SRS resource of the terminal equipment is 2; if the first number of transmitting antenna ports used by the terminal device is 6 and the second number of receiving antenna ports is 8, the network device determines that the total number of SRS resources of the terminal device is 2. Wherein, 1 SRS resource may be a 6 antenna port, and another SRS resource may be a 2 antenna port. Alternatively, 1 SRS resource may be a 4-antenna port and another SRS resource may be a 4-antenna port.

The specific process of the network equipment for determining the SRS resource information according to the total number of the SRS resources is as follows: and determining that the number of the SRS resource sets is smaller than or equal to the total number of the SRS resources, and determining the number of the SRS resources in each SRS resource set according to the number of the SRS resource sets and the total number of the SRS resources. For example, if the network device determines that the total number of SRS resources is 2 according to the first number and the second number, the number of SRS resource sets is 1 or 2, if the number of SRS resource sets is 1, 2 SRS resources are included in the SRS resource sets, and if the number of SRS resource sets is 2, 1 SRS resource is included in each SRS resource set.

Next, a procedure for the network device to determine SRS resource information of the terminal device will be described with reference to fig. 4.

Fig. 4 is a schematic diagram of a process for determining SRS resource information according to an embodiment of the present application. Please refer to fig. 4, which includes a network device and a terminal device. Wherein the network device determines that the antenna port of the terminal device is configured to: and 6 transmitting antenna ports and 8 receiving antenna ports, further determining that the total number of SRS resources of the terminal equipment is 2, and determining that the number of SRS resource sets of the terminal equipment is 2, wherein each resource set comprises 1 total number of SRS resources. The network device sends the antenna port configuration and the SRS resource information to the terminal device. The SRS resource information comprises 2 SRS resource sets, and each SRS resource set comprises 1 SRS resource information.

And S203, the network equipment sends the antenna port configuration and SRS resource information to the terminal equipment.

After the network device determines the antenna port configuration and the SRS resource information of the terminal device, the network device may send the antenna port configuration and the SRS resource information to the terminal device, so that the terminal device switches the used transmitting antenna port and receiving antenna port according to the antenna port configuration, and sends the SRS to the network device according to the SRS resource information. For example, the network device determines that the antenna port of the terminal device is configured to: 6 sending antenna ports and 6 receiving antenna ports, and further determining that the SRS resource information is: and 1 SRS resource set, wherein the SRS resource set comprises 1 SRS resource (namely the total SRS resource of the terminal equipment is 1), and the network equipment sends the antenna port configuration and the SRS resource information to the terminal equipment.

S204, the terminal equipment invokes a transmitting antenna port and a receiving antenna port of the terminal equipment according to the antenna port configuration and the SRS resource information.

Optionally, the terminal device may determine the number of transmitting antenna ports and the number of receiving antenna ports that may be used by the terminal device during data interaction according to the antenna port configuration, and the terminal device performs data transmission according to the SRS resource information. For example, the terminal device includes 10 transmitting antenna ports and 10 receiving antenna ports, and if the antenna ports received by the terminal device are configured as 6 transmitting antenna ports and 8 receiving antenna ports, the terminal device invokes the 6 transmitting antenna ports and the 8 receiving antenna ports when performing data interaction.

The embodiment of the application provides a resource configuration method, which comprises the steps of obtaining the number of transmitting antenna ports and the number of receiving antenna ports of a terminal device, determining antenna port configuration of the terminal device according to the number of transmitting antenna ports and the number of receiving antenna ports, wherein the antenna port configuration comprises a first number of transmitting antenna ports configured for the terminal device and a second number of receiving antenna ports configured for the terminal device, the first number is smaller than or equal to the second number, and a network device determines SRS resource information of the terminal device according to the first number and the second number and sends the antenna port configuration and the SRS resource information to the terminal device. In this way, when the number of transmitting antenna ports and the number of receiving antenna ports used by the terminal device are changed, the network device can flexibly adjust the SRS resource information configured for the terminal device, thereby improving the flexibility of resource configuration.

The above-described resource allocation method is described in detail below with reference to fig. 5, based on the embodiment shown in fig. 2.

Fig. 5 is a flowchart of another resource allocation method according to an embodiment of the present application. Referring to fig. 5, the method includes:

S501, the network equipment acquires the number of transmitting antenna ports and the number of receiving antenna ports of the terminal equipment.

It should be noted that the execution process of step S501 may be the same as the execution process of step S201, and the embodiments of the present application will not be described herein.

S502, the network equipment determines antenna port configuration of the terminal equipment according to the number of transmitting antenna ports and the number of receiving antenna ports, wherein the antenna port configuration comprises a first number of transmitting antenna ports and a second number of receiving antenna ports.

Next, by way of specific example, the antenna port configuration of the terminal device will be described in detail.

Case 1: the number of transmitting antenna ports of the terminal equipment is 6, and the number of receiving antenna ports is 6.

In this case, the terminal device antenna port configuration may be any of the following: the first number of transmit antenna ports is 1 and the second number of receive antenna ports is 6; alternatively, the first number of transmit antenna ports is 2 and the second number of receive antenna ports is 6; alternatively, the first number of transmit antenna ports is 4 and the second number of receive antenna ports is 6; alternatively, the first number of transmit antenna ports is 6 and the second number of receive antenna ports is 6.

Case 2: the number of transmitting antenna ports of the terminal equipment is 8, and the number of receiving antenna ports is 8.

In this case, the terminal device antenna port configuration may be any of the following: the first number of transmit antenna ports is 1 and the second number of receive antenna ports is 8; alternatively, the first number of transmit antenna ports is 2 and the second number of receive antenna ports is 8; alternatively, the first number of transmit antenna ports is 4 and the second number of receive antenna ports is 8; alternatively, the first number of transmit antenna ports is 6 and the second number of receive antenna ports is 8; alternatively, the first number of transmit antenna ports is 8 and the second number of receive antenna ports is 8.

When the first number of the transmitting antenna ports is 6 and the second number of the receiving antenna ports is 6, the network device configures the number of SRS resource sets for the terminal device to be 1, and the number of SRS resources in the SRS resource sets is 1. For example, when the first number of transmit antenna ports is 6 and the second number of receive antenna ports is 6, the total number of SRS resources of the terminal device is 1, and thus the number of SRS resource sets is 1, and only 1 SRS resource can be included in the SRS resource set.

Alternatively, the SRS resource set or SRS resource may be configured to be periodic or semi-persistent when the SRS resource is configured. For example, if the first number is 6 and the second number is 6, the periodic SRS resource information and the semi-persistent SRS resource information are respectively configured, and therefore the total number of SRS resources is 2, the number of SRS resource sets is 2 (one is periodic and the other is semi-persistent), and each SRS resource set includes 1 SRS resource.

Optionally, when the first number is 6 and the second number is 6, the number of ports of the SRS resource is an integer greater than or equal to 6. For example, the number of receiving antenna ports used by the terminal device is 6, and the SRS resource needs to traverse the antenna ports of the terminal device when communication is performed, so the number of ports corresponding to the SRS resource is an integer greater than or equal to 6.

Alternatively, in this case, since the number of SRS resource sets is 1 and the total number of SRS resources is 1, the SRS resource sets occupy one slot unit or the SRS resources occupy one slot unit.

Next, the structure of the terminal device in this case will be described with reference to fig. 6.

In the embodiment shown in fig. 6, the number of transmit antenna ports is 6, and the number of receive antenna ports is 6, please refer to fig. 6, which includes a receive antenna port and a power amplifier. Wherein the number of receiving antenna ports is 6 and the number of power amplifiers is 6. Each power amplifier has one port, i.e. the number of ports of SRS resources is 6. The terminal equipment can simultaneously select 6 antenna ports to transmit SRS at the same time, so that the accuracy of the detection result of the uplink channel communication quality can be improved.

Case 2: the first number of transmit antenna ports is 8 and the second number of receive antenna ports is 8.

When the first number of the transmitting antenna ports is 8 and the second number of the receiving antenna ports is 8, the network device configures the number of SRS resource sets for the terminal device to be 1, and the number of SRS resources in the SRS resource sets is 1. For example, when the first number of transmit antenna ports is 8 and the second number of receive antenna ports is 8, the total number of SRS resources of the terminal device is 1, and thus the number of SRS resource sets is 1, and only 1 SRS resource can be included in the SRS resource set.

Optionally, when the first number is 8 and the second number is 8, the number of ports of the SRS resource is an integer greater than or equal to 8. For example, the number of receiving antenna ports used by the terminal device is 8, and the SRS resource needs to traverse the antenna ports of the terminal device when communication is performed, so the number of ports corresponding to the SRS resource is an integer greater than or equal to 8.

The terminal equipment can simultaneously select 8 antenna ports to transmit SRS at the same time, so that the accuracy of the detection result of the uplink channel communication quality can be improved.

Case 3: the first number of transmit antenna ports is 6 and the second number of receive antenna ports is 8.

When the first number of the transmitting antenna ports is 6 and the second number of the receiving antenna ports is 8, the network equipment configures the number of SRS resource sets for the terminal equipment to be 1, and the number of SRS resources in the SRS resource sets is 2; or the number of SRS resource sets configured by the network equipment for the terminal equipment is 2, and the number of SRS resources in each SRS resource set is 1. For example, when the first number of transmitting antenna ports is 6 and the second number of receiving antenna ports is 8, the total number of SRS resources of the terminal device is 2, so the number of SRS resource sets is an integer less than or equal to 2, and when the number of SRS resource sets is 1, the SRS resource sets include 2 SRS resources; when the number of SRS resource sets is 2, only 1 SRS resource can be included in each SRS resource set.

Optionally, when the first number is 6 and the second number is 8, the number of ports of the SRS resource is an integer greater than or equal to 8. For example, the number of receiving antenna ports used by the terminal device is 8, and the SRS resource needs to traverse the antenna ports of the terminal device when communication is performed, so the number of ports corresponding to the SRS resource is an integer greater than or equal to 8.

Optionally, the number of SRS resource sets is 1, the SRS resource sets include 2 SRS resources, one SRS resource is an X port (port), and the other SRS resource is a Y port, and x+y needs to be greater than or equal to 8. For example, one is 6-port SRS resource, the other is 2-port SRS resource, or one is 4-port SRS resource, and the other is 4-port SRS resource, so that all antenna ports can be traversed, and the accuracy of channel communication quality detection can be improved.

Optionally, the number of SRS resource sets is 2, and each SRS resource set includes 1 SRS resource, where the SRS resource in one SRS resource set is an X port, and the SRS resource in the other SRS resource set is a Y port, and x+y needs to be satisfied to be greater than or equal to 8.

Optionally, when the number of SRS resource sets is 2, the 2 SRS resource sets occupy different slot units respectively or the 2 SRS resources occupy different slot units respectively.

Optionally, the terminal device supporting the antenna port configuration of 6 transmit antenna ports and 8 receive antenna ports also supports the antenna port configuration of 4 transmit antenna ports and 8 receive antenna ports, where the terminal device may report a capability combination message to the base station (e.g., 4t8r_6t8r, where t is the transmit antenna port R is the receive antenna port).

Next, the structure of the terminal device in this case will be described with reference to fig. 8.

Wherein the number of receiving antenna ports is 8 and the number of power amplifiers is 6. Each power amplifier has at least one port such that the number of ports of SRS resources is 8. For example, the 2 power amplifiers all include 2 ports, the 4 power amplifiers all include 1 port, so that the port number of the SRS resource is 8, and in this way, the terminal device can simultaneously select 8 antenna ports to transmit the SRS at the same time, so that the accuracy of the detection result of the uplink channel communication quality can be improved.

According to the example shown in table 2, corresponding SRS resource information may be allocated to terminal devices configured for different antenna ports. For example, taking 6T10R as an example, K is 5, so that the value of Nmax is 5,N includes 1, 2, 3, 4, and 5, and when N is 1, 5 SRS resources are included in the SRS resource set; when N is 2, 3 SRS resources are included in one SRS resource set, 2 SRS resources are included in the other SRS resource set, or 1 SRS resource is included in one SRS resource set, and 4 SRS resources are included in the other SRS resource set; when N is 3, the first SRS resource set includes 1 SRS resource, the second SRS resource set includes 1 SRS resource, and the third SRS resource set includes 3 SRS resource sets, or the first SRS resource set includes 2 SRS resources, the second SRS resource set includes 2 SRS resources, and the third SRS resource set includes 1 SRS resource; when N is 4, one SRS resource set comprises 2 SRS resources, and four SRS resource sets respectively comprise 1 SRS resource; when N is 5, each SRS resource set includes 1 SRS resource.
