Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a communication method, an apparatus, and a computer storage medium. Background Art

[0002] For a network adopting the Massive Multiple-Input Multiple-Output (Massive MIMO) antenna technology, as the scale of antennas increases, the corresponding base station radio frequency transceiver channel modules increase, resulting in high power consumption.

[0003] In a Hybrid BeamForming (HBF) antenna architecture, there is a corresponding relationship between the base station radio frequency transceiver channels and the beams. When a beam is turned off, the corresponding radio frequency transceiver channel module is turned off. Therefore, to save power consumption, the sparsity of the spatial channel can be utilized to only turn on the beams with served terminals and turn off other useless beams.

[0004] When a beam is turned off, the signal transmitted thereon will not be sent, and the corresponding time-frequency resources will be released. Currently, the time-frequency resources released by the signals transmitted on the turned-off beams cannot be used by other downlink channels, resulting in resource waste. Summary of the Invention

[0025] In the above optional embodiment, by determining a target signal in a target signal set with a reduced scope relative to the entire signal set (i.e., the above periodic signal set), the number of target signals for which the time-frequency resources occupied by the target signal can be indicated for transmitting the PDSCH can be reduced, which can reduce the resource overhead of the first indication message and improve the transmission efficiency between the network device and the terminal device.

[0060] Next, the embodiments of the present application will be described in detail with reference to the accompanying drawings in the embodiments of the present application.

[0061] Please refer to Figure 1 , Figure 1 It is a schematic flowchart of a communication method provided by an embodiment of the present application. Among them, the communication method can be specifically applied to a communication network, and the communication network includes a network device and a terminal device. 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 a mobile phone (such as an Android mobile phone, an iOS mobile phone, etc.), a tablet computer, a desktop computer, a Mobile Internet Device (MID), and a Personal Digital Assistant (PDA), etc. As Figure 1 shown, the communication method includes the following steps:

[0062] S11. The network device determines a target signal in the set of periodic signals.

[0063] When a beam is turned off, the network device determines a target signal in the set of periodic signals. Among them, the target signal is transmitted on at least one beam, and the at least one beam is turned off.

[0064] In an embodiment of the present application, the set of periodic signals includes a synchronization signal block (SSB) burst set and / or one or more channel state information reference signal (CSI-RS) sets. Wherein, the SSB burst set includes one or more SSBs, and each CSI-RS set includes one or more CSI-RSs.

[0065] Thus, when the set of periodic signals includes the SSB burst set, the target signal may be the SSB in the SSB burst set; when the set of periodic signals includes one or more CSI-RS sets, the target signal may be the CSI-RS in the one or more CSI-RS sets.

[0066] S12. The network device sends a first indication message to the terminal device.

[0067] In an embodiment of the present application, the first indication message is used to indicate the first signal identifier of the target signal.

[0068] Specifically, when the target signal is an SSB, the first signal identifier is the SSB identifier (SSB ID) of the SSB.

[0069] 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.

[0070] Correspondingly, the terminal device receives the first indication message from the network device. In an embodiment of the present application, the set of periodic signals is pre-configured in the terminal device by the network device. Thus, 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 set of periodic signals.

[0071] In an embodiment of the present application, the first indication message may be a downlink control information (DCI) or a control unit (MAC control element, MAC CE) message of media access control (MAC). A specified field in the DCI or MAC CE message is used to indicate the first signal identifier of the target signal.

[0072] Wherein, the DCI may be a DCI for scheduling the PDSCH or a DCI not for scheduling the PDSCH.

[0073] Among them, the effective time of the MAC CE message is not earlier than the end time of the last symbol of the channel of the Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) message corresponding to the PDSCH carrying the MAC CE message.

[0074] In a 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 further send an activation message to the terminal device. Wherein, the activation message carries an activation instruction.

[0075] Correspondingly, the terminal device receives the activation message from the network device, and in response to the activation instruction, activates 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 becomes effective.

[0076] S13. The network device sends a Physical Downlink Shared Channel (PDSCH) to the terminal device on all or part of the time-frequency resources in the time-frequency resources occupied by the target signal.

[0077] Correspondingly, on all or part of the time-frequency resources in the time-frequency resources occupied by the target signal, the terminal device receives the PDSCH from the network device.

[0078] In a specific implementation process, the network device may send the PDSCH to the terminal device only on all or part of the time-frequency resources in the time-frequency resources occupied by the target signal;

[0079] Alternatively, the network device may send the PDSCH to the terminal device on all or part of the time-frequency resources in the time-frequency resources occupied by the target signal, and on the time-frequency resources other than the time-frequency resources occupied by each signal in the periodic signal set.

[0080] In the embodiments of the present application, by using the time-frequency resources released when the beam is turned off (i.e., the time-frequency resources occupied by the target signal) for transmitting the PDSCH, the downlink resource utilization efficiency of the communication network can be improved, and resource waste can be reduced.

[0081] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of another communication method provided by the embodiments of the present application. Among them, the communication method can be specifically applied to a network device. As Figure 2As shown, the communication method includes the following steps:

[0082] S21. Send a second indication message to the terminal device.

[0083] In the embodiments of the present application, the second indication message may be a system message or a Radio Resource Control (RRC) message.

[0084] Among them, the system message may be a Master Information Block (MIB) or a System Information Block (SIB). The SIB may be a Remaining Minimum System Information (RMSI) or other system information blocks (OSI). Among them, RMSI is also referred to as System Information Block type 1 (SIB1), and OSI is the SIB other than SIB1.

[0085] In the embodiments of the present application, the second indication message is used to indicate the second signal identifier corresponding to the target signal set. Among them, the target signal set is a proper subset of the periodic signal set, and the beams for transmitting each signal in the target signal set can be turned off.

[0086] In the embodiments of the present application, the periodic signal set is pre-configured in the terminal device by the network device. Among them, the periodic signal set includes an SSB burst set and / or one or more CSI-RS sets; the SSB burst set includes one or more SSBs, and each CSI-RS set includes one or more CSI-RSs.

[0087] Therefore, when the periodic signal set includes an SSB burst set, the target signal set may include all or part of the SSBs in the SSB burst set;

[0088] And / or, when the periodic signal set includes one or more CSI-RS sets, the target signal set may include all CSI-RS sets in the one or more CSI-RS sets, or the target signal set may include part of the CSI-RS sets in the one or more CSI-RS sets and / or part of the CSI-RSs in part of the CSI-RS sets in the one or more CSI-RS sets.

[0089] Specifically, when the periodic signal set only includes an SSB burst set, the target signal set includes part of the SSBs in the SSB burst set.

[0090] When the set of periodic signals only includes one or more CSI-RS sets, the target signal set may include some CSI-RS sets in the one or more CSI-RS sets (i.e., the target signal set may include all CSI-RS in some CSI-RS sets in the one or more CSI-RS sets) and / or some CSI-RS in some CSI-RS sets in the one or more CSI-RS sets.

[0091] When the set of periodic signals includes an SSB burst set and one or more CSI-RS sets at the same time, the target signal set may include all SSBs in the SSB burst set, or the target signal set may include all CSI-RS sets in the one or more CSI-RS sets.

[0092] In an embodiment of the present application, each CSI-RS is a periodic CSI-RS or a semi-persistent CSI-RS, and each periodic CSI-RS is a periodic non-zero power CSI-RS or a periodic zero power CSI-RS, and each semi-persistent CSI-RS is a semi-persistent non-zero power CSI-RS or a semi-persistent zero power CSI-RS.

[0093] Further, when the target signal set includes an SSB burst set, the second signal identifier includes the set ID of the SSB burst set.

[0094] When the target signal set includes one or more CSI-RS sets, the second signal identifier includes the set IDs of the one or more CSI-RS sets.

[0095] When the target signal set includes one or more SSBs, the second signal identifier includes the SSB IDs of the one or more SSBs.

[0096] When the target signal set includes one or more CSI-RSs, the second signal identifier includes the signal identifier of each CSI-RS. Among them, the signal identifier of each CSI-RS includes the CSI-RS ID of the CSI-RS and the set ID of the CSI-RS set where the CSI-RS is located.

[0097] S22. Determine the target signal in the target signal set.

[0098] When there is a beam turned off, the network device determines the target signal in the target signal set. Among them, the target signal is transmitted on at least one beam, and the at least one beam is turned off. In a specific implementation process, the network device may determine one or more target signals in the set of periodic signals, and the beams used to transmit the one or more target signals are turned off.

[0099] S23. Send a first indication message to the terminal device.

[0100] In an embodiment of the present application, the first indication message may be DCI for scheduling PDSCH; alternatively, the first indication message may be a MAC CE message or DCI not for scheduling PDSCH.

[0101] In an embodiment of the present application, the first indication message is used to indicate a first signal identifier of the target signal.

[0102] Specifically, when the target signal is an SSB, the first signal identifier is the SSB ID of the SSB.

[0103] When the target signal is a CSI-RS, the first signal identifier includes the CSI-RS ID of the CSI-RS and / or the set ID of the CSI-RS set where the CSI-RS is located.

[0104] S24. Send PDSCH to the terminal device on all or part of the time-frequency resources occupied by the target signal.

[0105] When the first indication message is DCI for scheduling PDSCH, the indication function of the first indication message takes effect once, that is, after sending the first indication message to the terminal device, the network device may send the PDSCH scheduled this time to the terminal device on all or part of the time-frequency resources occupied by the target signal.

[0106] When the first indication message is a MAC CE message or DCI not for scheduling PDSCH, the indication function of the first indication message takes effect semi-persistently, that is, within the time period after sending the first indication message and before sending an indication message for indicating the first signal identifier of the target signal again, the network device may send PDSCH to the terminal device on all or part of the time-frequency resources occupied by the target signal.

[0107] In an embodiment of the present application, by using the time-frequency resources released when the beam is turned off (that is, the time-frequency resources occupied by the target signal) for transmitting PDSCH, the downlink resource utilization efficiency of the communication network can be improved and resource waste can be reduced. In addition, by configuring a target signal set with a reduced range relative to the entire signal set (that is, the above-mentioned periodic signal set) and determining the target signal in the target signal set, the number of beams that can be turned off is reduced, so that the number of target signals for which the time-frequency resources occupied can be indicated for transmitting PDSCH is reduced, and the resource overhead of the first indication message can be reduced, and the transmission efficiency between the network device and the terminal device can be improved.

[0108] In a specific implementation process, the target signal set may also be the same set as the periodic signal set. Thus, the beams used to transmit each signal in the periodic signal set can be turned off. In this case, the embodiments of the present application can maximize the downlink resource utilization efficiency of the communication network and reduce resource waste.

[0109] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of another communication method provided by the embodiments of the present application. Among them, this communication method can be specifically applied to a terminal device. As Figure 3 shown, this communication method includes the following steps:

[0110] S31. Receive a second indication message from a network device.

[0111] In the embodiments of the present application, the second indication message may be a system message or RRC. Among them, the system message may be MIB or SIB.

[0112] In the embodiments of the present application, the second indication message is used to indicate a second signal identifier corresponding to a target signal set. Among them, the target signal set is a proper subset of the periodic signal set.

[0113] In the embodiments of the present application, the periodic signal set includes an SSB burst set and / or one or more CSI-RS sets. Among them, the SSB burst set includes one or more SSBs, and each CSI-RS set includes one or more CSI-RSs.

[0114] S32. Determine the target signal set from the periodic signals according to the second signal identifier.

[0115] In the embodiments of the present application, the terminal device is pre-configured with the periodic signal set by the network device. By adding the signals in the periodic signal set whose signal identifiers correspond to the second signal identifier to the target signal set, the terminal device can determine the target signal set.

[0116] In the embodiments of the present application, when the periodic signal set includes an SSB burst set, the target signal set may include all or part of the SSBs in the SSB burst set;

[0117] And / or, when the set of periodic signals includes one or more CSI-RS sets, the target signal set may include all CSI-RS sets in the one or more CSI-RS sets, or the target signal set may include some CSI-RS sets in the one or more CSI-RS sets and / or some CSI-RS in some CSI-RS sets in the one or more CSI-RS sets.

[0118] In the embodiments of the present application, each CSI-RS is a periodic CSI-RS or a semi-persistent CSI-RS, and each periodic CSI-RS is a periodic non-zero power CSI-RS or a periodic zero power CSI-RS, and each semi-persistent CSI-RS is a semi-persistent non-zero power CSI-RS or a semi-persistent zero power CSI-RS.

[0119] S33. Receive a first indication message from a network device.

[0120] In the embodiments of the present application, the first indication message may be a DCI for scheduling a PDSCH; or the first indication message may be a MAC CE message or a DCI not for scheduling a PDSCH.

[0121] In the embodiments of the present application, the first indication message is used to indicate a first signal identifier of a target signal.

[0122] S34. Determine a target signal in the target signal set according to the first signal identifier.

[0123] In the embodiments of the present application, the terminal device may determine the signal in the target signal set whose signal identifier corresponds to the first signal identifier as the target signal.

[0124] S35. Receive a PDSCH from the network device on all or part of the time-frequency resources occupied by the target signal.

[0125] When the first indication message is a DCI for scheduling a PDSCH, the indication function of the first indication message takes effect once, that is, after receiving the first indication message from the network device, the terminal device may receive the PDSCH scheduled this time from the network device on all or part of the time-frequency resources occupied by the target signal.

[0126] When the first indication message is a MAC CE message or DCI not used for scheduling the PDSCH, the indication function of the first indication message takes effect semi - persistently. That is, within the time period after receiving the first indication message from the network device and before receiving again from the network device an indication message for the first signal identifier of the target signal, the terminal device can receive the PDSCH from the network device on all or part of the time - frequency resources occupied by the target signal in the configured time - frequency resources.

[0127] In the embodiments of the present application, by using the time - frequency resources released when the beam is turned off (i.e., the time - frequency resources occupied by the target signal) for transmitting the PDSCH, the downlink resource utilization efficiency of the communication network can be improved and resource waste can be reduced. In addition, by configuring a target signal set with a reduced range relative to the entire signal set (i.e., the above - mentioned periodic signal set) and determining the target signal in the target signal set, the number of beams that can be turned off is reduced, so that the number of target signals for which the time - frequency resources occupied can be indicated for transmitting the PDSCH is reduced, which can reduce the resource overhead of the first indication message and improve the transmission efficiency between the network device and the terminal device.

[0128] Please refer to Figure 4 , Figure 4 is a schematic framework diagram of a network device provided by an embodiment of the present application. As Figure 4 shown, the network device 40 may include a processing module 41 and a transceiver module 42.

[0129] Among them, the processing module 41 is used to determine the target signal in the periodic signal set.

[0130] The transceiver module 42 is used to send a first indication message to the terminal device.

[0131] Among them, the first indication message is used to indicate the first signal identifier of the target signal.

[0132] The transceiver module 42 is further used to send the PDSCH to the terminal device on all or part of the time - frequency resources occupied by the target signal.

[0133] As an optional implementation manner, the periodic signal set includes an SSB burst set and / or a CSI - RS set.

[0134] As an optional implementation manner, the CSI - RS set includes periodic CSI - RS and / or semi - persistent CSI - RS.

[0135] As an optional implementation manner, the periodic signal set includes an SSB burst set, and the target signal is the SSB in the SSB burst set.
