Background technique

In the hybrid beamforming (Hybrid BeamForming, HBF) antenna architecture, the base station's RF transceiver channel and the beam have a corresponding relationship, and the corresponding RF transceiver channel module is turned off when the beam is turned off. Therefore, in order to save power consumption, the sparsity of the spatial channel can be used, only the beam with the service terminal is turned on, and other useless beams are turned off.

When the beam is turned off, the signal transmitted on it will not be sent, and the corresponding time-frequency resources will be released. At present, the time-frequency resources released by signals transmitted on the turned-off beam cannot be used by other downlink channels, resulting in a waste of resources.

Please refer to FIG. 1, which is a schematic flowchart of a communication method provided by an embodiment of the present application. Wherein, the communication method can be specifically applied to a communication network, and the communication network includes network equipment and terminal equipment. In practical applications, the network device can be a mobile communication base station, including but not limited to macro base stations, micro base stations, omnidirectional stations, etc.; the terminal device can be mobile phones (such as Android phones, iOS phones, etc.), tablet computers, desktop computers , Mobile Internet Devices (MID) and Personal Digital Assistant (PDA), etc. As shown in Figure 1, the communication method includes the following steps:

S11. The network device determines the target signal in the periodic signal set.

When a beam is turned off, the network device determines the target signal in the periodic signal set. Wherein, the target signal is transmitted on at least one beam, and the at least one beam is turned off.

In the embodiment of the application, the periodic signal set includes a synchronization signal block (Synchronization Signal Block, SSB) burst set and/or one or more channel state information reference signal (Channel State Information Reference Signal, CSI-RS) sets . The SSB burst set includes one or more SSBs, and each CSI-RS set includes one or more CSI-RS.

Therefore, when the periodic signal set includes an SSB burst set, the target signal may be the SSB in the SSB burst set; when the periodic signal set includes one or more CSI-RS sets, the target signal may be The CSI-RS in the one or more CSI-RS sets.

S12. The network device sends a first indication message to the terminal device.

In this embodiment of the present application, the first indication message is used to indicate the first signal identifier of the target signal.

Specifically, when the target signal is an SSB, the first signal identifier is the SSB identifier (SSB ID) of the SSB.

When the target signal is a CSI-RS, the first signal identifier includes the CSI-RS identifier (CSI-RS ID) of the CSI-RS and/or the set identifier (set ID) of the CSI-RS set where the CSI-RS is located. ).

Correspondingly, the terminal device receives the first indication message from the network device. In the embodiment of the present application, the terminal device is pre-configured with the periodic signal set by the network device. Therefore, according to the first signal identifier of the target signal indicated by the first indication message, the terminal device can determine the target signal in the periodic signal set.

In this embodiment of the application, the first indication message may be a downlink control information (Downlink Control Information, DCI) or a medium access control (Medium Access Control, MAC) control element (MAC Control Element, MAC CE) message. The designated field in the DCI or MAC CE message is used to indicate the first signal identifier of the target signal.

Wherein, the DCI may be DCI used for scheduling the PDSCH or DCI not used for scheduling the PDSCH.

Wherein, the effective time of the MAC CE message is no earlier than the end time of the last symbol of the channel of the hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat reQuest ACKnowledgement, HARQ-ACK) message corresponding to the PDSCH carrying the MAC CE message.

In the specific implementation process, if the periodic signal set includes semi-persistent CSI-RS, after the network device configures the periodic signal set for the terminal device, the network device may also send activation to the terminal device news. Wherein, the activation message carries an activation instruction.

Correspondingly, the terminal device receives the activation message from the network device, and responds to the activation instruction to activate the semi-persistent CSI-RS in the periodic signal set. When the terminal device successfully activates the semi-persistent CSI-RS, the semi-persistent CSI-RS takes effect.

S13. The network device sends a Physical Downlink Shared Channel (PDSCH) to the terminal device on all or part of the time-frequency resources configured and occupied by the target signal.

S22. Determine the target signal in the target signal set.

When a beam is turned off, the network device determines the target signal in the target signal set.

When the first indication message is a MAC CE message or a DCI that is not used to schedule PDSCH, the indication function of the first indication message takes effect semi-continuously, that is, after the first indication message is sent, it is sent again for indication During the time period before the indication message of the first signal identifier of the target signal, the network device can send the PDSCH to the terminal device on all or part of the time-frequency resources configured and occupied by the target signal.

In the embodiment of the present application, the time-frequency resources released when the beam is turned off (that is, the time-frequency resources occupied by the target signal) are used to transmit the PDSCH, which can improve the utilization efficiency of downlink resources of the communication network and reduce Waste of resources. In addition, the number of beams that can be turned off can be reduced by configuring a target signal set with a reduced range relative to the signal full set (ie, the above-mentioned periodic signal set) and determining the target signal in the target signal set, thereby reducing the number of beams that can be turned off, thereby reducing the configuration occupation The time-frequency resources of can be indicated for the number of target signals used to transmit the PDSCH, which can reduce the resource overhead of the first indication message, and improve the transmission efficiency between the network device and the terminal device.
