According to the capacity, speed, delay and other factors of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network can also be called a new wireless network ( New Radio, NR). For convenience of description, the present disclosure will sometimes refer to a wireless communication network simply as a network.

The wireless access network equipment may be: a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay A node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc., can also be a gNB in an NR system, or can also be a component or part of a device that constitutes a base station Wait. When it is a vehicle-to-everything (V2X) communication system, the network device may also be an in-vehicle device.

In a multi-carrier communication system, data transmission can be performed between network devices and terminals based on beams to meet higher rate requirements. For example, multi-carrier communication in the millimeter wave frequency band of the fifth-generation communication is the main technical feature of communication technology. In order to ensure that both the terminal and the network device can select the optimal beam and ensure the best connection performance, the beam needs to be managed. In a multi-carrier system, the network device performs beam management on the terminal according to different beam management capabilities reported by the terminal. Among them, the beam management capability supported by the terminal includes supporting the unified beam management capability or supporting the independent beam management capability. According to the beam management capability reported by the terminal, the network device statically performs unified beam management or independent beam management.

However, the beam performance during the communication process of the terminal will change dynamically, and the network equipment performs static unified beam management or independent beam management, which will affect the communication performance. For example, when a terminal and a network device communicate based on two carriers, carrier A and carrier B, the terminal can only report support for unified beam management or independent beam management. In the case where the terminal reports unified beam management, when carrier A and carrier B perform downlink reception in the same beam direction, the peaks of the receiving beams of carrier A and carrier B may be inconsistent, which may lead to inconsistencies in carrier A or carrier B. The reception performance on carrier B deteriorates. When the terminal reports independent beam management, carrier A and carrier B perform beam measurement and report beam measurement results respectively. However, when carrier A and carrier B have similar beam receiving capabilities, unified beam management can be performed, so Independent beam management adds unnecessary signaling overhead.

With the development of communication technology, the capabilities of terminals are also continuously enhanced. Among them, the terminal with enhanced capability can support unified beam management and independent beam management at the same time. The network device can also perform flexible beam management according to the capability reported by the terminal.

In step S42, the semi-static beam management indication information is received.

In an example, the terminal reports capability information that supports both unified beam management and independent beam management through new terminal capability reporting signaling, such as beamManagementType-r17. After receiving the terminal capability reporting signaling (supporting both unified beam management and independent beam management), the network device delivers the instruction information for semi-static beam management to the terminal.

The terminal receives the shaped reference signal sent by the network device, and based on the shaped reference signal, performs beam measurement and reports the beam measurement result.

In the multi-carrier communication method provided by the embodiment of the present disclosure, the network device may determine the beam management type (uniform beam management or independent beam management) applicable to the terminal based on the beam receiving performance of the terminal, and determine the beam management type applicable to the terminal based on the beam management type applicable to the terminal. The carrier on which the shaped reference signal is transmitted. For the convenience of description, the carrier that the network device sends the shaped reference signal to the terminal is called the designated carrier.

In step S51, a shaped reference signal is received on a designated carrier among the plurality of carriers.

In step S52, beam measurement and beam measurement result reporting is performed on the designated carrier.

In the embodiment of the present disclosure, the designated carrier for the terminal to receive the shaping reference signal is determined based on the management type applicable to the terminal. For example, on the one hand, when the network device determines that the terminal applies unified beam management, the designated carrier is one of the multiple carriers. On the other hand, when the network device determines that the terminal uses independent beam management, the designated carrier is each of the multiple carriers.

In an example, the multi-carrier communication system includes two carriers, carrier A and carrier B, as an example for description. For example, in the case where the network device determines that the terminal is suitable for unified beam management, the network device can only send a shaped reference signal (CSI-RS) on carrier A, and the terminal only performs corresponding beam measurement on carrier A and reports the beam measurement result. For another example, if the network device determines that the terminal uses independent beam management, the network device can send a shaping reference signal (CSI-RS) on carrier A and carrier B respectively, and the terminal performs beam measurement and beam measurement on carrier A and carrier B respectively. Reporting of measurement results.

In the multi-carrier communication method provided by the embodiment of the present disclosure, the beam management type applicable to the terminal can change dynamically. For example, on the one hand, the type of beam management applicable to the terminal may be changed from a situation suitable for unified beam management to a situation suitable for independent beam management. On the other hand, the type of beam management applicable to the terminal may also change from a case applicable to independent beam management to a case applicable to unified beam management.

After receiving the terminal capability reporting signaling (supporting both unified beam management and independent beam management), the network device delivers the instruction information for semi-static beam management to the terminal. The terminal receives the semi-static beam management indication information. After the network device sends the semi-static beam management indication information, if the network device determines that the beam management type applicable to the terminal is unified beam management, it can only send the shaping reference signal (CSI-RS) on the carrier A, and the terminal passes the Carrier A receives a shaped reference signal (CSI-RS), and performs corresponding beam measurement on carrier A and reports the beam measurement result. When the network device monitors the signal on carrier B and the performance in the corresponding beam direction deteriorates, the network device determines that the beam management type applicable to the terminal can be dynamically switched from the unified beam management to the independent beam management for carrier B. , sending a shaping reference signal (CSI-RS) to carrier B to trigger beam measurement on carrier B and reporting of beam measurement results. The terminal receives a shaped reference signal (CSI-RS) through carrier B, and performs corresponding beam measurement on carrier B and reports the beam measurement result.

In an example, the terminal reports capability information that supports both unified beam management and independent beam management through new terminal capability reporting signaling, such as beamManagementType-r17. After receiving the terminal capability reporting signaling (supporting both unified beam management and independent beam management), the network device delivers the instruction information for semi-static beam management to the terminal. The terminal receives the semi-static beam management indication information. After the network device sends the semi-static beam management indication information, if the network device determines that the beam management type applicable to the terminal is independent beam management, the network device sends the shaping reference signal (CSI-RS) on carrier A and carrier B respectively. ), the terminal receives a shaped reference signal (CSI-RS) on carrier A and carrier B, respectively, and performs beam measurement and beam measurement result reporting on carrier A and carrier B. When the network device monitors that the beam directions on carrier A and carrier B are very similar, the network device determines that the beam management type applicable to the terminal can be switched from the case of independent beam management to the case of unified beam management, then the network device can send on carrier A. Shaped reference signal (CSI-RS), the terminal only performs the corresponding beam measurement on carrier A and reports the beam measurement result.
