Based on the above, the embodiment of the application provides a communication method, which can realize the sending strategy for distinguishing a plurality of panels.

The communication method, the device, the chip and the module device provided by the embodiment of the application are further described in detail below.

Referring to fig. 2, fig. 2 is a flow chart of a communication method according to an embodiment of the application. As shown in fig. 2, the communication method includes the following steps S201 to S202:

s201, downlink control information (downlink control information, DCI) from the network device is received.

In some possible embodiments, when a network device needs to schedule a terminal device supporting simultaneous transmission of multiple antenna panels, the network device may determine and send DCI to the terminal device. Accordingly, the terminal device receives DCI from the network device. The DCI may include first indication information and SRS resource set configuration information. It may be appreciated that the first indication information may be used to indicate a transmission policy configured for the terminal device, and the SRS resource set configuration information may include at least one SRS resource set, where one SRS resource set is associated with one network device and/or one antenna panel, that is, one SRS resource set is associated with one network device, or one SRS resource set is associated with one antenna panel, or one SRS resource set is associated with one network device and one antenna panel. For easy understanding, the following embodiments of the present application mainly take one SRS resource set to associate one network device and one antenna panel as an example for schematic description.

In the following, the different network devices are mainly exemplified by 2 different network devices. Wherein the 2 network devices are referred to as a first network device and a second network device, respectively. Here, a network device may be understood as a TRP, and thus a first network device may also be described as a first TRP, and a second network device may also be described as a second TRP.

It should be noted that, the first indication information in the embodiment of the present application may be carried in an srsrsresourcesetting indicator field included in the DCI or may also be carried in a newly added field of the DCI, which is not limited herein. It is understood that the field length for carrying the first indication information may be 3 bits, 4 bits or more, and the like, which is not limited herein. For convenience of understanding, the following embodiments of the present application mainly take an example that a field length carrying the first indication information is 3 bits as an example for schematic description. The different values of the field are used to indicate different transmission strategies, for example, when the first indication information is 000, the PUSCH is sent to the first network device and the second network device through the 2 antenna panels respectively. For another example, when the first indication information is 001, the PUSCH is alternately transmitted to the first network device and the second network device through the 2 antenna panels, respectively. Or when the first indication information is 000, the first indication information is used for indicating that the PUSCH is alternately transmitted to the first network device and the second network device through the 2 antenna panels respectively. For another example, when the first indication information is 001, the PUSCH and the like are indicated to be transmitted to the first network device and the second network device through the 2 antenna panels, respectively. Different strategies corresponding to different values can be determined according to actual application scenes, and the method is not limited.

6. The first SRS resource set and the fourth SRS resource set indicate that the first SRI and/or the first TPMI are associated with the first SRS resource set, and the second SRI and/or the second TPMI are associated with the fourth SRS resource set.

7. The second SRS resource set and the third SRS resource set indicate that the first SRI and/or the first TPMI are associated with the second SRS resource set, and the second SRI and/or the second TPMI are associated with the third SRS resource set.

8. The second SRS resource set and the fourth SRS resource set indicate that the first SRI and/or the first TPMI are associated with the second SRS resource set, and the second SRI and/or the second TPMI are associated with the fourth SRS resource set.

When the terminal device may send PUSCH to 2 network devices based on 2 antenna panels, the network device that sends DCI to the terminal device may be any one of the 2 network devices, or may be another network device, i.e., a network device that does not receive PUSCH, or the like, which is not limited herein.

It should be noted that, in one possible implementation, when the terminal device has a capability/function of supporting simultaneous transmission of 2 antenna panels, the terminal device may send capability information of supporting simultaneous transmission of 2 antenna panels to the network device. Accordingly, when the network device receives the capability information from the terminal device, an activation command may be sent to the terminal device, where the activation command is used to activate the function that the terminal device supports simultaneous transmission of multiple antenna panels.
