Description

Multicarrier communication method, apparatus and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a multi-carrier communication method, apparatus, and storage medium.

Background

With the development of mobile communication technology, in order to meet the requirement of higher speed, high frequency, large bandwidth, large-scale antenna technology and multi-carrier aggregation technology are increasingly becoming the trend of wireless communication technology development. At present, a large-scale antenna technology and a multi-carrier aggregation technology have become main technical features of a millimeter wave frequency band of fifth-generation communication.

In the large-scale antenna 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 the multi-carrier system, the network equipment manages the wave beams of the terminal according to different wave beam management capacities reported by the terminal. The beam management capability supported by the terminal includes supporting a unified beam management capability or supporting an independent beam management capability. And the network equipment statically performs unified beam management or independent beam management on the terminal according to the beam management capability reported by the terminal.

However, in the case of unified beam management, when downlink reception is performed in the same beam direction by different carriers, the reception performance may be degraded on some carriers. In the case of independent beam management, different carriers perform beam measurement and beam measurement results, respectively, and when the receiving beam capabilities of the multiple different carriers are similar, unnecessary signaling overhead is increased.

Therefore, a new beam management method is provided and needs to be studied.

The multi-carrier communication method provided by the embodiment of the disclosure can be applied to the wireless communication system shown in fig. 1. Referring to fig. 1, the wireless communication system includes a terminal and a network device. The terminal is connected with the network equipment through wireless resources and transmits and receives data.

The number of network devices and the number of terminals included in the wireless communication system are not limited in the embodiments of the present disclosure.

It is further understood that the wireless communication system of the embodiment of the present disclosure is a network providing a wireless communication function. The wireless communication system may employ various communication technologies, such as Code Division Multiple Access (CDMA), wideband Code Division Multiple Access (WCDMA), time Division Multiple Access (TDMA), frequency Division Multiple Access (FDMA), orthogonal Frequency Division Multiple Access (OFDMA), single Carrier FDMA (SC-FDMA), carrier Sense Multiple Access/Collision Avoidance (Carrier Sense Multiple Access with collagen Access). Networks can be classified into 2G (english: generation) networks, 3G networks, 4G networks or future evolution networks, such as 5G networks, according to factors such as capacity, rate and delay of different networks, and the 5G networks can also be referred to as New Radio Networks (NR). For ease of description, this disclosure will sometimes simply refer to a wireless communication network as a network.

Further, the network devices referred to in this disclosure may also be referred to as radio access network devices. The radio access network device may be: a base station, an evolved node B (eNB), a home base station, an Access Point (AP), a wireless relay node, a wireless backhaul node, a Transmission Point (TP), a Transmission and Reception Point (TRP) in a wireless fidelity (WIFI) system, and the like, and may also be a gNB in an NR system, or may also be a component or a part of a device constituting the base station. When a vehicle networking (V2X) communication system, the network device may also be an in-vehicle device. It should be understood that, in the embodiments of the present disclosure, the specific technology and the specific device form adopted by the network device are not limited.

Further, a Terminal referred to in this disclosure may also be referred to as a Terminal device, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like, and is a device that provides voice and/or data connectivity to a User, for example, the Terminal may be a handheld device, a vehicle-mounted device, or the like having a wireless connection function. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a Pocket Computer (PPC), a palm top Computer, a Personal Digital Assistant (PDA), a notebook Computer, a tablet Computer, a wearable device, or a vehicle-mounted device, etc. Further, when being a vehicle networking (V2X) communication system, the terminal device may also be an in-vehicle device. It should be understood that the embodiments of the present disclosure do not limit the specific technologies and the specific device forms adopted by the terminal.

In the disclosed embodiments, multi-carrier communication is supported between a network device (e.g., a base station) and a terminal. The multi-carrier communication may be implemented based on a carrier aggregation technology, a Dual Connectivity (DC) technology, or may include a multi-RAT Dual connectivity (MRDC) technology of a multi-access system, such as EN-DC and NE-DC. The EN-DC refers to the dual connection of the 4G radio access network and the 5G NR, and the NE-DC refers to the dual connection of the 5G NR and the 4G radio access network.

In a multi-carrier communication system, data transmission can be performed between network equipment and a terminal based on beams, and the requirement of higher rate is met. For example, multicarrier communication in the millimeter wave band of fifth generation communication is a main technical feature in 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 management is required. In a multi-carrier system, network equipment manages beams for a terminal according to different beam management capabilities reported by the terminal. The beam management capability supported by the terminal includes supporting a unified beam management capability or supporting an independent beam management capability. And the network equipment statically performs unified beam management or independent beam management on the terminal according to the beam management capability reported by the terminal.

However, the beam performance of the terminal during communication may change dynamically, and the network device may perform static uniform beam management or independent beam management, which may affect the communication performance. For example, when the terminal communicates with the network device based on two carriers, i.e., carrier a and carrier B, the terminal may only report and support unified beam management or independent beam management. Under the condition that the terminal reports unified beam management, when a carrier wave A and a carrier wave B perform downlink reception in the same beam direction, the situation that the peak values of the receiving beams of the carrier wave A and the receiving beams of the carrier wave B are inconsistent may occur, and further, the receiving performance on the carrier wave A or the receiving performance on the carrier wave B may be poor. Under the condition that the terminal reports the independent beam management, the carrier wave A and the carrier wave B respectively carry out beam measurement and report the beam measurement result, however, when the beam receiving capacity of the carrier wave A and the carrier wave B is similar, the unified beam management can be carried out, so the independent beam management can increase unnecessary signaling overhead.

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

The embodiment of the disclosure provides a multi-carrier communication method, in which a terminal reports capability information simultaneously supporting unified beam management capability and independent beam management capability, and a network device performs semi-static beam management on the terminal through actual beam measurement, so that a receiving/transmitting beam of the terminal can be better scheduled, the terminal can select a better beam direction on all carriers, and signaling overhead can be saved.

Fig. 2 is a flowchart illustrating a multi-carrier communication method according to an exemplary embodiment, where the multi-carrier communication method is used in a terminal, as shown in fig. 2, and includes the following steps.

In step S11, capability information for instructing the terminal to simultaneously support the unified beam management capability and the independent beam management capability is transmitted.

In step S12, beam management indication information is received, where the beam management indication information is determined by the network device based on the capability information reported by the terminal.

In the multi-carrier communication method provided by the embodiment of the present disclosure, capability information that supports both the unified beam management capability and the independent beam management capability may be reported by introducing a new terminal capability reporting signaling. For example, capability information supporting both unified beam management capability and independent beam management capability may be reported through a beam management type (e.g., beamManagementType-R17) in R17.

In the multi-carrier communication method provided by the embodiment of the present disclosure, the terminal may receive the beam management indication information sent by the network device by receiving a signaling notification message sent by the network device. The signaling notification message may be Radio Resource Control (RRC) signaling, medium Access Control (MAC) signaling, RRC signaling, or MAC signaling.

In the multicarrier communication method provided by the embodiment of the present disclosure, the beam management indication information received by the terminal may include indication information for unified beam management, indication information for independent beam management, and indication information for indicating dynamic switching between unified beam management and independent beam management.

For convenience of description, in the embodiments of the present disclosure, the indication information indicating that the unified beam management and the independent beam management perform dynamic handover is referred to as semi-static beam management indication information. If the terminal receives the semi-static beam management indication information, the terminal may be understood as indication information that the terminal may receive unified beam management or indication information that the terminal may receive independent beam management.

In an implementation manner of the multi-carrier communication method provided by the embodiment of the present disclosure, the beam management indication information received by the terminal in the embodiment of the present disclosure includes indication information for unified beam management.

Fig. 3 is a flowchart illustrating a multi-carrier communication method according to an exemplary embodiment, where the multi-carrier communication method is used in a terminal, as shown in fig. 3, and includes the following steps.

In step S21, capability information for indicating that the terminal supports both the unified beam management capability and the independent beam management capability is transmitted.

In step S22, indication information for unified beam management is received.

In one example, the terminal reports signaling, such as beamManagementType-r17, through the new terminal capability, and reports capability information that supports both unified beam management and independent beam management. After receiving the terminal capability report signaling (supporting both unified beam management and independent beam management), the network device issues indication information for unified beam management to the terminal. The terminal receives indication information of unified beam management.

In another implementation manner of the multicarrier communication method provided by the embodiment of the present disclosure, the beam management indication information received by the terminal in the embodiment of the present disclosure includes indication information of independent beam management.

Fig. 4 is a flowchart illustrating a multi-carrier communication method according to an exemplary embodiment, where the multi-carrier communication method is used in a terminal, as shown in fig. 4, and includes the following steps.

In step S31, capability information for indicating that the terminal supports both the unified beam management capability and the independent beam management capability is transmitted.

In step S32, indication information of independent beam management is received.

In one example, the terminal reports signaling, such as beamManagementType-r17, through the new terminal capability, and reports capability information that supports both unified beam management and independent beam management. After receiving the terminal capability report signaling (supporting both unified beam management and independent beam management), the network device issues indication information for independent beam management to the terminal. The terminal receives indication information of the independent beam management.

In another implementation manner of the multi-carrier communication method provided by the embodiment of the present disclosure, the beam management indication information received by the terminal in the embodiment of the present disclosure includes semi-static beam management indication information.

Fig. 5 is a flowchart illustrating a multi-carrier communication method according to an exemplary embodiment, where the multi-carrier communication method is used in a terminal, as shown in fig. 5, and includes the following steps.

In step S41, capability information for indicating that the terminal supports both the unified beam management capability and the independent beam management capability is transmitted.

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

In one example, the terminal reports signaling, such as beamManagementType-r17, through the new terminal capability, and reports capability information that supports both unified beam management and independent beam management. After receiving the terminal capability reporting signaling (supporting both unified beam management and independent beam management), the network device issues indication information for performing semi-static beam management to the terminal. The terminal receives indication information of semi-static beam management.

In the embodiment of the disclosure, the terminal reports the capability information simultaneously supporting the unified beam management capability and the independent beam management capability, and the network device may determine the beam management indication information for performing beam management on the terminal based on the capability information and send the beam management indication information to the terminal. And the terminal receives the beam management indication information sent by the network equipment. The network device may flexibly manage the beam based on the beam measurement result of the terminal based on the capability information reported by the terminal, that is, issue different beam management indication information according to the beam measurement result.

In the multi-carrier communication method provided by the embodiment of the present disclosure, a network device sends a shaped Reference Signal, such as Channel State Information (CSI) -Reference Signal (Reference Signal RS), to a terminal. And the terminal receives a shaped reference signal sent by the network equipment, and performs beam measurement and beam measurement result reporting based on the shaped reference signal.

In the multi-carrier communication method provided by the embodiment of the present disclosure, the network device may determine a beam management type (unified beam management or independent beam management) applicable to the terminal based on the beam receiving performance of the terminal, and determine a carrier that transmits a forming reference signal to the terminal based on the beam management type applicable to the terminal. For convenience of description, a carrier for a network device to send a shaped reference signal to a terminal is referred to as a designated carrier.

Fig. 6 is a flowchart illustrating a multi-carrier communication method according to an exemplary embodiment, where the multi-carrier communication method is used in a terminal, as shown in fig. 6, and includes the following steps.

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

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

In the embodiment of the disclosure, the designated carrier for the terminal to receive the forming reference signal is determined based on the management type applicable to the terminal. For example, on the one hand, in case the network device determines that the terminal is adapted for unified beam management, the carrier is designated as one of the plurality of carriers. On the other hand, in the case where the network device determines that the terminal uses independent beam management, a carrier is designated as each of the plurality of carriers.

In an example, a multi-carrier communication system including two carriers, i.e., carrier a and carrier B, is described as an example. For example, in case that the network device determines that the terminal is suitable for unified beam management, the network device may send a forming reference signal (CSI-RS) only on the carrier a, and the terminal performs corresponding beam measurement and reporting of the beam measurement result only on the carrier a. For example, when the network device determines that the terminal uses independent beam management, the network device may send a formed reference signal (CSI-RS) on carrier a and carrier B, and the terminal performs beam measurement and reports beam measurement results on carrier a and carrier B, respectively.

In the multi-carrier communication method provided by the embodiment of the present disclosure, the beam management type applicable to the terminal may be dynamically changed. For example, in an aspect, the type of beam management applicable by the terminal may be changed from a case applicable to unified beam management to a case applicable to independent beam management. On the other hand, the beam management type applied to the terminal may be changed from the case of being applied to the individual beam management to the case of being applied to the unified beam management.

In the multi-carrier communication method provided by the embodiment of the present disclosure, a terminal switches to receive a designated beam of a shaped reference signal when a beam management type applicable to the terminal changes dynamically.

Fig. 7 is a flowchart illustrating a multi-carrier communication method according to an exemplary embodiment, where the multi-carrier communication method is used in a terminal, as shown in fig. 7, and includes the following steps.

In step S61, in response to a change in the beam management type applied by the terminal, the designated carrier of the shaped reference signal is dynamically switched and received.

In an implementation manner of the multi-carrier communication method provided by the embodiment of the present disclosure, a terminal may dynamically switch a designated carrier for receiving a shaped reference signal when receiving semi-static beam management indication information sent by a network device.

In one example, the terminal reports signaling via new terminal capabilities, such as beamManagementType-r17, reporting capability information that supports both unified beam management and independent beam management. After receiving the terminal capability report signaling (supporting unified beam management and independent beam management at the same time), the network device issues the indication information for semi-static beam management to the terminal. The terminal receives 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 the unified beam management, the network device may send a shaped reference signal (CSI-RS) only on the carrier a, and the terminal receives the shaped reference signal (CSI-RS) through the carrier a and performs corresponding beam measurement and reporting of the beam measurement result on the carrier a. When the network equipment monitors a signal on a carrier B and the performance is poor in the direction corresponding to the beam, the network equipment determines that the beam management type applicable to the terminal can be dynamically switched from the condition of unified beam management to the condition of independent beam management for the carrier B, sends a shaped reference signal (CSI-RS) to the carrier B, and triggers beam measurement on the carrier B and reporting of a beam measurement result. And the terminal receives a formed reference signal (CSI-RS) through a carrier B, and performs corresponding beam measurement and reporting of a beam measurement result on the carrier B.

In one example, the terminal reports signaling via new terminal capabilities, such as beamManagementType-r17, reporting capability information that supports both unified beam management and independent beam management. After receiving the terminal capability reporting signaling (supporting both unified beam management and independent beam management), the network device issues indication information for performing semi-static beam management to the terminal. The terminal receives semi-static beam management indication information. After the network equipment sends the semi-static beam management indication information, if the network equipment determines that the beam management type applicable to the terminal is the condition of independent beam management, the network equipment sends a shaped reference signal (CSI-RS) on a carrier A and a carrier B respectively, and the terminal receives the CSI-RS on the carrier A and the carrier B respectively and carries out beam measurement and beam measurement result reporting on the carrier A and the carrier B. When the network device monitors that the beam directions on the carrier wave A and the carrier wave B are very similar, the network device determines that the beam management type applicable to the terminal can be switched from the condition of independent beam management to the condition of unified beam management, then the network device can send a forming reference signal (CSI-RS) on the carrier wave A, and the terminal only carries out corresponding beam measurement and reporting of the beam measurement result on the carrier wave A.

In the multi-carrier communication method provided by the embodiment of the present disclosure, the network device may send a downlink beam indication to the terminal based on the beam measurement result reported by the terminal. The terminal receives the downlink beam indication sent by the network equipment, can adjust the beam direction, and carries out downlink reception on the corresponding carrier.

In an implementation manner of the multi-carrier communication method provided by the embodiment of the present disclosure, the network device sends the downlink beam indication to the terminal based on a designated carrier used when the terminal performs beam measurement and reports a beam measurement result. And the terminal receives the downlink beam indication sent by the network equipment on the designated carrier used when the beam measurement and the beam measurement result are reported.

In one embodiment, in response to that the designated carrier used when the terminal performs the beam measurement and reports the beam measurement result is one of the multiple carriers, that is, the case of performing the beam management is the case of performing unified beam management, the network device may send the same downlink beam indication for all the multiple carriers. And the terminal receives the same downlink beam indication corresponding to the multiple carriers and adjusts the beam direction based on the same downlink beam indication so as to receive the multiple carriers in the same beam direction.

Fig. 8 is a flowchart illustrating a multi-carrier communication method according to an exemplary embodiment, where the multi-carrier communication method is used in a terminal, as shown in fig. 8, and includes the following steps.

In step S71, when the terminal applies the unified beam management, the same downlink beam indication corresponding to the multiple carriers is received on each of the multiple carriers, and beam direction adjustment is performed based on the same downlink beam indication, so as to perform downlink reception on the multiple carriers in the same beam direction.

In an embodiment of the present disclosure, in an aspect, the terminal may receive the same downlink beam indication corresponding to the multiple carriers when receiving the unified beam management indication information. On the other hand, the terminal may receive the same downlink beam indication corresponding to the multiple carriers when receiving the semi-static beam management indication information.

In an example, the multi-carrier system including the carrier a and the carrier B is still taken as an example for explanation.

For the situation of the unified beam management indication information, the terminal reports signaling through a new terminal capability, such as beamManagementType-r17, and reports capability information supporting both unified beam management and independent beam management. After receiving the terminal capability report signaling (supporting both unified beam management and independent beam management), the network device issues indication information for unified beam management to the terminal. The terminal receives indication information for unified beam management. The network equipment only sends a forming reference signal (CSI-RS) on the carrier A, and the terminal only carries out corresponding beam measurement and beam measurement result reporting on the carrier A. And the network equipment sends the same downlink beam indication to the carrier A and the carrier B according to the beam measurement result reported by the terminal. And after receiving the same downlink beam indication corresponding to the multiple carriers, the terminal adjusts the beam direction and simultaneously receives the carrier A and the carrier B in the same beam direction.

For the case of semi-static beam management indication information, the terminal reports signaling through the new terminal capability, such as beamManagementType-r17, and reports capability information supporting both unified beam management and independent beam management. After receiving the terminal capability reporting signaling (supporting both unified beam management and independent beam management), the network device issues indication information for performing semi-static beam management to the terminal. The terminal receives semi-static beam management indication information.

And the terminal receives different downlink beam instructions sent by the network equipment, independently adjusts the beam direction of each carrier based on the different downlink beam instructions, and receives downlink in the beam direction corresponding to each carrier.

And the network equipment respectively sends corresponding different downlink beam indications to the carrier A and the carrier B according to the beam measurement result reported by the terminal. After receiving different downlink beam instructions, the terminal independently adjusts the beam direction of each carrier in the carrier A and the carrier B, and receives downlink on the carrier A and the carrier B in the corresponding beam direction.

For the case of semi-static beam management indication information, the terminal reports signaling through new terminal capability, such as beamManagementType-r17, and reports capability information supporting both unified beam management and independent beam management. After receiving the terminal capability reporting signaling (supporting both unified beam management and independent beam management), the network device issues indication information for performing semi-static beam management to the terminal. The terminal receives semi-static beam management indication information.

And the network equipment respectively sends corresponding different downlink beam indications to the carrier A and the carrier B according to the beam measurement result reported by the terminal.
