Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and a communication device. Background Art

[0002] In the process of the evolution of the fifth generation mobile communication system (5G) to 5G-advanced (5G-A) technology, communication and perception integration technology is considered to be one of the key technologies that can expand the business capabilities of mobile communication networks. The core idea of ​​this technology is to add perception capabilities to the mobile communication network and build the ability to detect, track and image the target, so that the two capabilities of communication and perception can be integrated into one network to achieve harmonious coexistence and even mutual benefit. There are certain differences between the technical principles of perception and communication. Communication is that the transmitter modulates information on radio waves and sends it to the receiver, and the receiver demodulates the signal carried on the radio waves to obtain information. Perception requires the transmitter to send radio waves in a specific direction. When the radio waves are irradiated on the surface of the target, reflected radio waves are formed. The receiver receives and processes the reflected radio waves to obtain information such as the location, speed and type of the target.

[0003] With the development of communication technology, terminal devices support simultaneous access to two network devices. This access mode is called dual connectivity (DC), in which one network device is the primary network device and the other network device is the secondary network device. For example, in the development and evolution of wireless communication systems, operators will deploy 5G new radio interface (NR) systems and long term evolution (LTE) systems at the same time. Terminal devices also support simultaneous access to LTE network devices and NR network devices. Because LTE is also called evolved universal terrestrial radio access (E-UTRA), this access mode is called evolved universal terrestrial radio access and new radio dual connectivity (E-UTRA NR dual connectivity, EN-DC). In EN-DC mode, the LTE network device is the primary network device and the NR network device is the secondary network device. Of course, with the evolution of the system, the future can also support NR E-UTRA dual connectivity (NE-DC), that is, the NR network device is the primary network device and the LTE network device is the secondary network device. Looking to the future, terminal devices will also access the 5G system and 5G's next-generation system at the same time.

[0004] When the terminal device receives the signals for perception from both the first RAT (such as 5G) and the second RAT (such as the next generation of 5G), the terminal device will determine the first perception amount and the second perception amount according to the signals received on the first RAT and the signals received on the second RAT, respectively, and send the first perception amount to the first network device through the first RAT, and send the second perception amount to the second network device through the second RAT.

[0074] The same applies to RTOA, A-AOA, Z-AOA, RSRP, radial velocity and radial velocity direction in the second perception quantity, which will not be elaborated here.

[0075] 304. The terminal device sends the first perception amount and the second perception amount to the first network device and / or sends the first perception amount and the second perception amount to the second network device. Accordingly, the first network device and / or the second network device may receive the first perception amount and the second perception amount from the terminal device.

[0076] That is, the terminal device may send the first perception amount and the second perception amount to the first network device.

Accordingly, the terminal device may receive the second indication information from the first network device. After receiving the second indication information, the terminal device sends the first perception quantity and the second perception quantity to the first network device and / or the second network device based on the indication of the second indication information. Based on this possible implementation method, the reporting method of the perception quantity can be made more flexible.

[0087] In a possible embodiment, the second indication information includes a third state and a fourth state; or, the second indication information includes a third state, a fourth state and a fifth state; wherein the third state indicates that the first perception amount and the second perception amount are sent to the first network device via the first RAT, the fourth state indicates that the first perception amount and the second perception amount are sent to the second network device via the second RAT, and the fifth state indicates that the first perception amount and the second perception amount are sent to the first network device via the first RAT, and the first perception amount and the second perception amount are sent to the second network device via the second RAT.

[0088] For example, the second indication information includes the third state and the fourth state. Assume that the second indication information has 1 bit. As shown in Table 2 below, if the value of the second indication information is 1, the second indication information indicates that the first perception amount and the second perception amount are sent to the first network device via the first RAT. If the value of the second indication information is 0, the second indication information indicates that the first perception amount and the second perception amount are sent to the second network device via the second RAT.

Alternatively, the terminal device may send the third perception amount to the second network device. Alternatively, the terminal device may send the third perception amount to the first network device and send the third perception amount to the second network device.

[0115] In the embodiment of the present application, after the first network device obtains the third perception quantity and / or the second network device obtains the third perception quantity, a more accurate perception measurement result can be obtained based on the third perception quantity.

Accordingly, the terminal device may receive the second indication information from the first network device. After receiving the second indication information, the terminal device sends the third perception amount to the first network device and / or the second network device based on the indication of the second indication information. Based on this possible implementation method, the reporting method of the perception amount can be made more flexible.

[0123] In a possible embodiment, the second indication information includes a third state and a fourth state; or, the second indication information includes a third state, a fourth state and a fifth state; wherein the third state indicates that a third perception amount is sent to the first network device via the first RAT, the fourth state indicates that the third perception amount is sent to the second network device via the second RAT, and the fifth state indicates that the third perception amount is sent to the first network device via the first RAT and the third perception amount is sent to the second network device via the second RAT.

If the value of the second indication information is 1, the second indication information indicates that the third perception amount is sent to the second network device via the second RAT. The second indication information may also include multiple bits, which is not limited in the embodiment of the present application.

[0128] For another example, take the example that the second indication information includes a third state, a fourth state, and a fifth state. Assume that the second indication information has 2 bits. As shown in Table 5 below, if the value of the second indication information is 00, the second indication information indicates that the third perception amount is sent to the first network device through the first RAT.
