[0032] See also Figure 2 , Figure 2 is a flow chart of an antenna panel control method provided by an embodiment of the present invention, such as Figure 2 As shown, the following steps are included:

[0033] Step 201, determining a first antenna panel to be closed;

[0034] Step 202: Control the first antenna panel to be in a closed state.

[0035] The panel control method provided by the embodiment of the present invention is applied to a terminal device having at least two antenna panels. After the terminal device is turned on, each antenna panel can be configured to be in an open state, that is, uplink (Upload, UL) or downlink (Download, DL) transmission can be performed through any antenna panel. The above-mentioned antenna panel specifically refers to: a reference signal resource set (RSresource set), a beam set, an antenna panel defined by a network display, a terminal radio frequency channel, spatial related information (aspatialRelationInfo), a downlink reference signal resource group / cluster (a group of DL RS resources), a transmission configuration indication state group / cluster (a group of TCI states), a power control unit (a unit of power control) or a timing / timing control unit (a unit of timing control), etc.

[0036] Specifically, in this embodiment, the first antenna panel to be closed can be actively selected and controlled by the user, or can be controlled by the network side device, and an antenna panel that meets preset conditions can be determined as the first antenna panel to be closed by a pre-agreed agreement. When the user actively chooses to control the first antenna panel to be closed of the terminal device, the open or closed state of each antenna panel can be set through a designated setting interface, and after determining the first antenna panel, the panel information of the first antenna panel is indicated to the network side device; when the first antenna panel to be closed is controlled by the network side device, the network side device can indicate the panel information of the first antenna panel to the terminal device.

[0037] After the terminal device determines the first antenna panel to be turned off, the first antenna panel can be turned off. The specific behavior of turning off the first antenna panel is described in detail in the following embodiments. It should be noted that the above-mentioned first antenna panel can be part or all of the antenna panels of the terminal device. It should be understood that the above-mentioned first antenna panel usually refers to an antenna panel whose channel quality to the network may be very poor. This part of the antenna panel consumes a lot of power and time-frequency resources, but contributes little to the communication quality, resulting in a waste of energy and time-frequency resources.

[0038] The embodiment of the present invention turns off the first antenna panel after determining the first antenna panel to be turned off, so that part or all of the antenna panels of the terminal device can be turned off, thereby reducing the power consumption of the terminal device and extending the standby time of the terminal device.

[0039] In an optional embodiment, the first antenna panel that needs to be turned off may be controlled by the network side device. For example, the network side device may send a first notification message to the terminal device to notify the first antenna panel that needs to be turned off. Specifically, in this embodiment, the above step 201 includes:

[0040] Receiving a first notification message sent by a network side device;

[0041] The first antenna panel is determined according to the first notification message.

[0042] In this embodiment, the first notification message may directly notify the terminal device of the first antenna panel to be turned off, or may indirectly notify the terminal device of the first antenna panel to be turned off, which is described in detail below.

[0043] It should be noted that the above-mentioned first notification message can be sent through any one of physical layer signaling, medium access control (Medium Access Control, MAC) signaling and radio resource control (Radio Resource Control, RRC) signaling.

[0044] Solution 1: The network-side device directly notifies the network-side device of the first antenna panel to be shut down through a first notification message.

[0045] In solution 1, the first notification message may be sent in any of the following ways.

[0046] Mode 1: indicating that a second antenna panel is in an open state, where the second antenna panel is an antenna panel other than the first antenna panel among all antenna panels of the terminal device;

[0047] Mode 2: indicating that the first antenna panel is in a closed state;

[0048] Mode three: indicating that the first antenna panel is in a closed state, and indicating that the second antenna panel is in an open state;

[0049] Mode 4: instructing a third antenna panel to switch from an open state to a closed state, wherein the third antenna panel is at least one antenna panel among the antenna panels currently in the open state;

[0050] Mode 5: instructing a fourth antenna panel to switch from a closed state to an open state, wherein the fourth antenna panel is at least one antenna panel among the antenna panels currently in the closed state.

[0051] In the above-mentioned method 1, the first notification message can inform which antenna panels are in the open state, so as to determine that the unnotified antenna panel is the first antenna panel. In the above-mentioned method 2, the first notification message can inform which antenna panels are in the closed state, so as to determine that the notified antenna panel is the first antenna panel. In the above-mentioned method 3, the first notification message can inform which antenna panels are in the closed state and which antenna panels are in the open state, so as to determine that the notified antenna panel in the closed state is the first antenna panel. In the above-mentioned method 4 and method 5, it is used to notify the antenna panel of the state transition. Specifically, in method 4, the antenna panel in the open state is adjusted to the closed state. At this time, it can be determined that the antenna panel that was previously in the closed state and the antenna panel indicated by the first notification message are the first antenna panel; in method 5, the antenna panel in the closed state is adjusted to the open state. At this time, it can be determined that the panels in the previously closed state except the antenna panel in the first notification message are the first antenna panel.

[0052] Solution 2: The network-side device indirectly notifies the terminal device of the first antenna panel to be turned off through a first notification message.

[0053] In solution 2, the first notification message may include at least one of downlink measurement information, a sounding reference signal (SRS) initially configured by the network side device for the terminal device, an SRS activated by the network side device for the terminal device, and target information;

[0054] The target information is initial configuration information or activation configuration information for the terminal device to receive data, or the target information is initial configuration information or activation configuration information for the terminal device to receive control information.

[0055] In this embodiment, the above-mentioned first notification message can specifically indicate the first antenna panel through one or more of the downlink measurement information, the detection reference signal SRS initially configured by the network side device for the terminal device, the SRS activated by the network side device for the terminal device, and the target information, which is described in detail below.

[0056] For example, in an optional implementation manner, when the first notification message includes downlink measurement information and the first target parameter, the above step 201 includes any one of the following:

[0057] Determine the antenna panel corresponding to the panel information not included in the downlink measurement information as the first antenna panel;

[0058] Determine the antenna panel corresponding to the panel information not included in the first target parameter as the first antenna panel, where the first target parameter is a sounding reference signal SRS initially configured by the terminal device or an SRS activated by the network side device for the terminal device;

[0059] An intersection or union of an antenna panel corresponding to the panel information not included in the downlink measurement information and an antenna panel corresponding to the panel information not included in the first target parameter is determined as the first antenna panel.

[0060] In this embodiment, the first antenna panel may be indicated by the downlink measurement information or the first target parameter alone, or the first antenna panel may be indicated by combining the downlink measurement information and the first target parameter. Specifically, when combined, the antenna panel corresponding to the panel information not included in both the downlink measurement information and the first target parameter may be determined as the first antenna panel; the antenna panel corresponding to the panel information not included in the downlink measurement information and the antenna panel corresponding to the panel information not included in the first target parameter may also be determined as the first antenna panel.

[0061] There may be multiple types of the above-mentioned SRS, for example, SRS for beam management (i.e., SRS for BM, BM refers to beam management Beam Management), codebook-based SRS (i.e., codebook based SRS), non-codebook-based SRS (i.e., Non-codebook based SRS) and SRS for antenna panel selection. In this embodiment, the antenna panel corresponding to the panel information not included in the above-mentioned first target parameter is: the antenna panel corresponding to the panel information not included in the first target object in the first target parameter, and the first target object is the SRS of all SRS except the SRS for beam management (i.e., SRS for BM, BM refers to beam management Beam Management).

[0062] The above-mentioned downlink measurement information includes a second target parameter, which is a synchronization signal block (Synchronization Signal and PBCH block, SSB) or a channel state information reference signal (ChannelState Information Reference Signal, CSI-RS). The antenna panel corresponding to the panel information not included in the downlink measurement information is: the antenna panel corresponding to the panel information included in the first target object in the second target parameter, and the first target object is the SSB in the SSB except the SSB used for beam management (ie, SSB for BM), or the CSI-RS in the CSI-RS except the CSI-RS used for beam management (ie, CSI-RS for BM).

[0063] In another optional implementation, when the first notification message includes the target information, determining the first antenna panel to be shut down includes:

[0064] The first antenna panel is determined according to the third target parameter in the target information, where the third target parameter is panel information of the second antenna panel or the third target parameter is associated with the second antenna panel; the second antenna panel is the antenna panel of all antenna panels of the terminal device except the first antenna panel.

[0065] In this embodiment, the target information includes a transmission configuration indicator state (TCI state), and the third target parameter is a parameter in the TCI state. The third target parameter is a target reference signal, and the second antenna panel is a panel corresponding to the target reference signal in the beam report.

[0066] Specifically, in this embodiment, the above-mentioned beam report may be the beam report most recently reported by the terminal device, and the beam report may include one or more antenna panels corresponding to the target reference signal, and when the antenna panel corresponding to the target reference signal is at least two first target antenna panels, the second antenna panel is the antenna panel with the best reporting result among the at least two first target antenna panels. For example, the antenna panel with the best reporting result refers to an antenna panel with the highest Reference Signal Received Power (RSRP) or signal-to-noise and interference ratio (SINR) in the reporting result.

[0067] In another optional embodiment, the user may actively control the first antenna panel that needs to be turned off. Specifically, the user may choose whether to turn off the antenna panel according to different usage scenarios, or the terminal device may recommend an antenna panel that can be turned off based on the beam measurement results, so that the user can select the first antenna panel to be turned off. After determining the first antenna panel, the terminal device sends a second notification message to the network side device to notify the terminal device of the first antenna panel that needs to be turned off. Specifically, based on the above embodiment, in this embodiment, after the above step 201, it also includes: sending a second notification message to the network side device, so that the network side device determines the first antenna panel according to the second notification message.

[0068] It should be noted that the above-mentioned second notification message can be sent through any one of physical layer signaling, medium access control MAC signaling and radio resource control RRC signaling.

[0069] In this embodiment, the second notification message may directly notify the network side device of the first antenna panel to be shut down, or may indirectly notify the network side device of the first antenna panel to be shut down, which is described in detail below.

[0070] Solution 3: The terminal device directly notifies the network-side device through a second notification message that the first antenna panel of the terminal device is to be turned off.

[0071] In solution 1, the second notification message may be sent in any of the following ways.

[0072] Mode six: indicating that a second antenna panel is in an open state, where the second antenna panel is an antenna panel other than the first antenna panel among all antenna panels of the terminal device;

[0073] Mode seven: indicating that the first antenna panel is in a closed state;

[0074] Mode eight: indicating that the first antenna panel is in a closed state, and indicating that the second antenna panel is in an open state;

[0075] Mode nine: instructing a third antenna panel to switch from an open state to a closed state, wherein the third antenna panel is at least one antenna panel among the antenna panels currently in the open state;

[0076] Mode ten: instructing a fourth antenna panel to switch from a closed state to an open state, wherein the fourth antenna panel is at least one antenna panel among the antenna panels currently in the closed state.

[0077] In the above-mentioned method 6, the second notification message can inform which antenna panels are in the open state, and the network side device can determine that the unnotified antenna panel is the first antenna panel. In the above-mentioned method 7, the second notification message can inform which antenna panels are in the closed state, and the network side device can determine that the notified antenna panel is the first antenna panel. In the above-mentioned method 8, the second notification message can inform which antenna panels are in the closed state and which antenna panels are in the open state, and the network side device can determine that the notified antenna panel in the closed state is the first antenna panel. In the above-mentioned method 9 and method 10, it is used to notify the antenna panel of the state transition. Specifically, in method 9, the antenna panel in the open state is adjusted to the closed state. At this time, the network side device can determine that the antenna panel of the terminal device that was previously in the closed state and the antenna panel indicated by the second notification message are the first antenna panel, and can also determine that the antenna panel indicated by the second notification message is the first antenna panel; in method 10, the antenna panel in the closed state is adjusted to the open state. At this time, the network side device can determine that the panel of the antenna panel of the terminal device that was previously in the closed state except the antenna panel in the first notification message is the first antenna panel.

[0078] Solution 4: The terminal device indirectly notifies the network-side device through a second notification message that the first antenna panel of the terminal device is to be turned off.

[0079] In scheme 4, the above-mentioned second notification message may include at least one of a beam report and an SRS sent to the network side device.

[0080] When the second notification message includes a beam report, the terminal device indicates the first antenna panel to a network side device through the beam report.

[0081] Specifically, the manner of indicating the first antenna panel through the beam report includes any one of the following:

[0082] The antenna panel corresponding to the panel information not included in the beam report is the first antenna panel;

[0083] The second target antenna panel implicitly indicated by the beam report is the first antenna panel;

[0084] The antenna panel corresponding to the panel information not included in the beam reports sent for the most recent N times and at least the beam reports sent for the most recent M times is the first antenna panel;

[0085] The second target antenna panel implicitly indicated by the beam reports sent for the most recent N times and the beam reports sent for at least M times is the first antenna panel;

[0086] Wherein, N is an integer greater than 1, and M is a positive integer less than or equal to N.

[0087] In this embodiment, each of the beam reports includes the measurement results of at least one antenna panel; specifically, the beam report does not include the panel information of the second target antenna panel: the beam report does not include the measurement results of the second target antenna panel; the beam report implicitly indicates the second target antenna panel: the beam report indicates that the measurement results of the second target antenna panel are lower than a preset threshold value.

[0088] In addition, when the second notification message includes SRS, the terminal device indicates the first antenna panel to the network side device through the SRS.

[0089] Specifically, the method of indicating the first antenna panel through the SRS includes any one of the following:

[0090] The antenna panel corresponding to the panel information not included in the SRS is the first antenna panel;

[0091] The antenna panel corresponding to the panel information not implicitly indicated in the SRS is the first antenna panel;

[0092] The antenna panel corresponding to the panel information not included in the SRS sent in the most recent N times and at least the SRS sent in the most recent M times is the first antenna panel;

[0093] The antenna panel corresponding to the panel information not implicitly indicated by the SRS sent N times and at least M times in the most recent SRS is the first antenna panel;

[0094] Wherein, N is an integer greater than 1, and is a positive integer less than or equal to N.

[0095] In this embodiment, the panel information included in the above SRS is: the panel information included in the first target object in the SRS, the first target object is the SRS used for beam management, or the SRS other than the SRS used for beam management in all SRSs. The antenna panel corresponding to the panel information implicitly indicated in the L-th transmitted SRS is: the antenna panel corresponding to the L-th unsent SRS, where L is a positive integer less than or equal to N.

[0096] It should be noted that, in this embodiment, the values ​​of M and N can be configured by the network side device through physical layer signaling, medium access control MAC signaling or other high-layer signaling. In this embodiment, the above panel information can be a resource set resource set of the SRS used for beam management (i.e., resource set of SRS for BM), or spatial related information spatial Relation Info of all SRSs except the SRS used for beam management (i.e., spatialRelationInfo of Other SRS), etc.

[0097] Furthermore, in another optional embodiment, if an antenna panel that meets preset conditions is determined as the first antenna panel to be shut down through a pre-agreement agreement, there is no need to send a notification message, thereby reducing signaling consumption.

[0098] In this embodiment, the step 201 includes: determining a first antenna panel whose duration of not performing uplink and / or downlink transmission reaches a preset duration.

[0099] Specifically, the method for counting the time when no uplink transmission and / or downlink transmission is performed can be set according to actual needs. For example, in this embodiment, the network-side device and the terminal device can use a counter and a timer to count the time when there is no uplink transmission, no downlink transmission, or neither uplink nor downlink transmission. Take the case of no uplink transmission as an example. Each time an uplink transmission occurs, the timer is restarted. When the timer reaches the maximum threshold configured by the network, it is considered that the terminal device has no uplink transmission for a period of time. Alternatively, an additional counter is used. When the timer reaches the maximum threshold configured by the network, the counter counts once and restarts the timer. When the counter reaches the maximum threshold configured by the network, it is considered that the terminal device has no uplink transmission for a period of time.

[0100] Furthermore, the counter may be a statistic of continuous no transmission, i.e., when transmission occurs, the counter is restarted; or, the counter may be a statistic of no transmission within a period of time T, i.e., when a transmission is sent, the counter is not restarted, but simply stops counting; as time goes by, the counter discards statistics whose distance from the current time exceeds T.

[0101] The network-side device and the terminal device can determine the first antenna panel that has not performed uplink and / or downlink transmission for a duration that reaches a preset time length according to the above method. After determining the first antenna panel, the terminal device can control part or all of the antenna panels of the first antenna panel to be in a closed state. It should be noted that in this embodiment, when the above terminal device includes a second antenna panel in addition to the first antenna panel, all antenna panels in the first antenna panel can be controlled to be in a closed state; when all antenna panels of the above terminal device are first antenna panels, some of the antenna panels in the first antenna panel can be controlled to be in a closed state. In this way, it can be ensured that after the antenna panel is turned off, the terminal device can still communicate normally.

[0102] It should be noted that the length of the above-mentioned preset duration may be controlled by radio resource control, medium access control element (MAC CE) or downlink control information (DCI).

[0103] Specifically, in this embodiment, not performing uplink transmission includes: not sending data information and control information on the first antenna panel.

[0104] SRS can also be transmitted on the first antenna panel. There can be multiple types of SRS, for example, SRS for beam management (i.e., SRS for BM, BM refers to beam management), codebook-based SRS, non-codebook-based SRS, and SRS for antenna panel selection. In an optional embodiment, the transmission of SRS for beam management may be taken as a special case or not. The transmission of SRS for beam management may be regarded as an uplink transmission, and the transmission of SRS for beam management may be regarded as no uplink transmission. That is, the above-mentioned non-uplink transmission includes or does not include: sending a target sounding reference signal SRS on the first antenna panel, and the target SRS is an SRS for beam management. When the transmission of SRS for beam management can be taken as a special case, the transmission of SRS for beam management can be regarded as no uplink transmission.

[0105] In this embodiment, when the third target antenna panel in the first antenna panel is in a closed state, if it is necessary to send a target SRS on the third target antenna panel, the third target antenna panel can be temporarily opened to send the target SRS. Specifically, after the above step 202, the following may also be included:

[0106] Sending a target SRS on the third target antenna panel, wherein the target SRS is an SRS for beam management;

[0107] After sending the target SRS, closing the third target antenna panel again;

[0108] Wherein, when the target SRS is sent on the third target antenna panel, the transmission delay of the network side device includes an additional delay, and the additional delay is used to indicate the time when the first antenna panel is opened.

[0109] In the above situation, the network side device needs to leave a delay large enough to meet the time of opening the third target antenna panel; the network side device can report the time of opening the third target antenna panel to the network side device, or the time of opening the third target antenna panel can be pre-agreed by agreement. In this embodiment, the above target SRS can be non-periodic.

[0110] Furthermore, the repetition setting of the second target object is turned on.

[0111] Further, based on the above embodiment, in this embodiment, before the above step 201, the following steps are further included:

[0112] Receive target information sent by network side equipment;

[0113] The target information is initial configuration information or activation configuration information for the terminal device to receive data, or the target information is initial configuration information or activation configuration information for the terminal device to receive control information.

[0114] In this embodiment, the third target parameter of the target information includes or implicitly indicates panel information of a second antenna panel, and the second antenna panel is an antenna panel other than the first antenna panel among the antenna panels of the terminal device. The network side device configures the panel information of the second antenna panel used by the terminal device for downlink transmission through the target information. The terminal device and the network side device can determine whether downlink transmission is performed according to the panel information of the configured second antenna panel.

[0115] Specifically, the target information includes a transmission configuration indication state TCI state, the third target parameter is a parameter in the TCI state, the third target parameter is a target reference signal, and the second antenna panel is an antenna panel corresponding to the target reference signal in the beam report beam report.

[0116] In this embodiment, the above beam report may be the beam report most recently reported by the terminal device, and the beam report may include one or more antenna panels corresponding to the target reference signal. When the antenna panel corresponding to the target reference signal is at least two first target antenna panels, the second antenna panel is the antenna panel with the best reporting result among the at least two first target antenna panels. For example, the antenna panel with the best reporting result refers to the antenna panel with the highest RSRP or SINR in the reporting result.

[0117] The synchronization signal block SSB or channel state information reference signal CSI-RS for beam management can also be transmitted on the first antenna panel. There may be multiple types of SSB or CSI-RS, for example, SSB or CSI-RS for beam management (i.e., SSB / CSI-RS for BM, BM refers to beam management), codebook-based SSB or CSI-RS, non-codebook-based SSB or CSI-RS, and SSB or CSI-RS for antenna panel selection.

[0118] In an optional embodiment, the transmission of SSB or CSI-RS for beam management may be taken as a special case or not. The reception of SSB or CSI-RS for beam management may be regarded as a downlink transmission, and the reception of SSB or CSI-RS for beam management may be regarded as no downlink transmission. That is to say, the above-mentioned non-downlink transmission includes or does not include: receiving a second target object on the first antenna panel, and the second target object is the SSB or CSI-RS for beam management. When the transmission of SSB or CSI-RS for beam management can be taken as a special case, the reception of SSB or CSI-RS for beam management can be regarded as no downlink transmission.

[0119] In this embodiment, when the fourth target antenna panel in the first antenna panel is in a closed state, if it is necessary to receive the second target object at the fourth target antenna panel, the fourth target antenna panel can be temporarily opened to receive the second target object. Specifically, after the above step 202, the following may also be included:

[0120] When a fourth target antenna panel in the first antenna panel is in a closed state, controlling the fourth target antenna panel to open;

[0121] Sending a second target object on the fourth target antenna panel, where the second target object is a synchronization signal block SSB or a channel state information reference signal CSI-RS for beam management;

[0122] After sending the second target object, closing the fourth target antenna panel again;

[0123] Wherein, when the second target object is sent on the fourth target antenna panel, the transmission delay of the network side device includes an additional delay, and the additional delay is used to indicate the time when the first antenna panel is opened.

[0124] In the above situation, the delay that the network side device needs to reserve must be large enough to meet the time for opening the fourth target antenna panel; the terminal device can report to the network side device the time for opening the fourth target antenna panel, or the time for opening the fourth target antenna panel can be agreed in advance.

[0125] It should be noted that, in this embodiment, the second target object may be non-periodic; and the repetition setting of the second target object may be in an on state.

[0126] The above-mentioned second target object includes SSB or CSI-RS. For example, for a non-periodic SSB / CSI-RS for BM configured with a repetition setting of "off" (repetition is "off", i.e., P2), the terminal device cannot use the first antenna panel to receive the second target object; for a non-periodic SSB / CSI-RS for BM configured with a repetition setting of "on" (repetition is "on", i.e., P1 or P3), the terminal device can use the panel to receive the second target object.

[0127] If the antenna panel that meets the preset conditions is determined as the first antenna panel to be closed through a pre-agreement, in order to ensure normal communication functions, the terminal device needs to ensure that at least one antenna panel is in an open state. Specifically, in this embodiment, the above step 202 includes: if the terminal device includes a second antenna panel other than the first antenna panel, then all antenna panels of the first antenna panel are controlled to be in a closed state; if the terminal device does not include a second antenna panel other than the first antenna panel, then the fifth target antenna panel in the first antenna panel is controlled to be in a closed state, and the sixth target antenna panel in the second antenna panel is controlled to be in an open state.

[0128] In this embodiment, when the duration of all the antenna panels of the above-mentioned terminal device without performing uplink and / or downlink transmission reaches a preset time length (that is, the above-mentioned first antenna panel is all the antenna panels in the terminal device), at this time, except for the antenna panel that needs to be turned on by default (that is, the above-mentioned sixth antenna panel), the remaining antenna panels will be turned off.

[0129] Specifically, in this embodiment, the sixth antenna panel is any one of the following antenna panels:

[0130] Antenna panel for Physical Uplink Control Channel (PUCCH) reception;

[0131] Physical Uplink Shared Channel (PUSCH) receives the corresponding antenna panel;

[0132] Antenna panel for receiving physical downlink control channel PDCCH;

[0133] The antenna panel corresponding to the physical downlink shared channel PDSCH reception;

[0134] The antenna panel of the most recent dispatch;

[0135] The best beam corresponds to the antenna panel.

[0136] Among them, the above-mentioned antenna panel 1 can specifically be a panel corresponding to the control related information dedicated to the PUCCH with the smallest ID in the PUCCH resource (that is, the Panel corresponding to the spatial relationinfo corresponding to the smallest ID PUCCH in the Dedicated PUCCH resource). The above-mentioned antenna panel 3 can specifically be an antenna panel corresponding to the first control resource set (that is, the Panel corresponding to CORESET#0) or all panels used for PDCCH reception. The above-mentioned antenna panel 4 can specifically be an antenna panel corresponding to the PUSCH default beam scheduled by the downlink control information of format 0-0 (that is, the Panel corresponding to the PUSCH default beam scheduled by DCI 0-0).

[0137] Further, after determining the first antenna panel, the first antenna panel may be closed. Specifically, in this embodiment, the step 202 includes:

[0138] Turn off the sending module and / or receiving module of the first antenna panel.

[0139] In this embodiment, when the first antenna panel is turned off, only the sending module may be turned off, only the receiving module may be turned off, or both the sending module and the receiving module may be turned off. Wherein, turning off the sending module of the first antenna panel includes:

[0140] Not transmitting uplink service data and / or control information on the first antenna panel;

[0141] Allowing or not allowing transmission of a codebook-based SRS and a non-codebook-based SRS on the first antenna panel;

[0142] enabling or disabling transmission of an SRS for beam management on the first antenna panel;

[0143] When a codebook-based SRS, a non-codebook-based SRS or an SRS for beam management is transmitted on the first antenna panel, the transmission delay of the network side device includes an additional delay, and the additional delay is used to indicate the time when the first antenna panel is opened.

[0144] In this embodiment, the codebook-based SRS, the non-codebook-based SRS, and the SRS for beam management are special transmission cases, and the corresponding SRS may be allowed to be sent on the first antenna panel, or it may not be allowed to be sent on the first antenna panel. Specifically, when it is allowed to send the SRS for beam management on a certain antenna panel in the first antenna panel, when it is necessary to send the SRS for beam management, the antenna panel may be temporarily opened, and then the SRS for beam management may be sent on the antenna panel, and then the antenna panel may be closed. In the above situation, the delay that the network-side device needs to leave must be large enough to meet the time to open the antenna panel; the network-side device may report the time to open the antenna panel to the network-side device, or the time to open the antenna panel may be pre-agreed by agreement.

[0145] It should be noted that, in this embodiment, the SRS for beam management allowed to be sent on the first antenna panel is non-periodic. Further, the terminal device can use the first antenna panel to send all types or some types of non-periodic SRS for BM. Specifically, the three types of non-periodic SRS for BM may include: both the network side device and the terminal device change the beam direction; only the terminal device changes the beam direction; only the network side device changes the beam direction.

[0146] Further, closing the receiving module of the first antenna panel includes:

[0147] Not transmitting downlink service data and / or control information on the first antenna panel;

[0148] allowing or not allowing reception of a reference signal corresponding to first downlink channel state information CSI on the first antenna panel, where the reference signal corresponding to the first downlink CSI is a reference signal not used for beam management;

[0149] allowing or not allowing reception of a reference signal corresponding to a second CSI on the first antenna panel, where the reference signal corresponding to the second CSI is a reference signal used for beam management;

[0150] When a reference signal corresponding to a first downlink CSI or a reference signal corresponding to a second downlink CSI is received on the first antenna panel, the transmission delay of the network side device includes an additional delay, and the additional delay is used to indicate the time when the first antenna panel is opened.

[0151] In this embodiment, the reference signal corresponding to the first CSI and the reference signal corresponding to the second CSI are reception exceptions, which may be allowed to be received on the first antenna panel or may not be allowed to be received on the first antenna panel. Specifically, when it is allowed to receive the corresponding reference signal on a certain antenna panel in the first antenna panel, when it is necessary to receive the corresponding reference signal, the antenna panel can be temporarily opened, and then the corresponding reference signal can be received on the antenna panel, and then the antenna panel can be closed. In the above situation, the delay that the network side device needs to reserve must be large enough to meet the time to open the antenna panel; the network side device can report the time to the network side device to open the antenna panel, or the time to open the antenna panel can be pre-agreed by agreement.

[0152] Furthermore, when it is necessary to receive a reference signal corresponding to the first CSI and / or a reference signal corresponding to the second CSI on the first antenna panel, and it is also necessary to transmit at least one of a codebook-based SRS, a non-codebook-based SRS, and an SRS for beam management on the first antenna panel, the two are transmitted at as close a time as possible, so as to avoid opening the first antenna panel multiple times and reduce the opening time of the first antenna panel.

[0153] It should be noted that, in one embodiment, the reference signal corresponding to the second CSI allowed to be received on the first antenna panel may be non-periodic, periodic or semi-periodic. In another embodiment, the reference signal corresponding to the second CSI is only non-periodic.

[0154] Further, in one embodiment, repetition of the reference signal corresponding to the second CSI is set to an on state or an off state.

[0155] For example, the reference signal corresponding to the above-mentioned second CSI includes SSB or CSI-RS. Specifically, for a non-periodic SSB / CSI-RS for BM configured with a repetition setting of "off" (repetition is "off", i.e., P2), the terminal device cannot use the first antenna panel to receive the reference signal corresponding to the second CSI; for a non-periodic SSB / CSI-RS for BM configured with a repetition setting of "on" (repetition is "on", i.e., P1 or P3), the terminal device can use the panel to receive the reference signal corresponding to the second CSI.

[0156] It should be noted that the second antenna panel in the terminal device other than the first antenna panel is in an open state. Specifically, the second antenna panel is in an open state when: the second antenna panel is allowed to transmit service data, control information and reference signals.

[0157] It should be noted that the various optional implementation modes introduced in the embodiments of the present invention may be implemented in combination with each other or may be implemented separately, and the embodiments of the present invention are not limited to this.

[0158] Furthermore, in order to better understand the present invention, three different implementation processes are described in detail below: the first antenna panel is determined by a network side device, is determined by a user's active selection, or is determined based on time.

[0159] In one implementation, the process of determining the first antenna panel by the network side device is specifically as follows:

[0160] Step 1: The network side device notifies the terminal device to close the first antenna panel;

[0161] In step 1, notification method 1 and notification method 2 are included, wherein method 1 is that the network side device explicitly notifies the terminal device to turn off the first antenna panel through display signaling; method 2 is that the network side device indirectly notifies the terminal device to turn off the first antenna panel.

[0162] In the above notification mode 1, the display signaling may include: physical layer signaling, medium access control signaling or radio resource control signaling. The display signaling may be notified to the first antenna panel in any of the following ways:

[0163] a) Tell which panels are open

[0164] b) Tell which panels are closed

[0165] c) Tell all panels whether they are open or closed

[0166] d) Tell which panels are changed from open to closed or from closed to open.

[0167] In the above notification method 2, the terminal device can be indirectly notified of the closed first antenna panel through the DL measurement information and / or designated SRS configured by the network side device to the terminal device. The designated SRS is the SRS activated by the network side device for the terminal device or the SRS initially configured by the network side device for the terminal device.

[0168] Specifically, in the first embodiment, it can be determined that the panel corresponding to the panel information not included in the DL measurement information is the first antenna panel; in the second embodiment, it can be determined that the panel corresponding to the panel information not included in the specified SRS is the first antenna panel; in the third embodiment, it can be determined that the panel corresponding to the panel information not included in both the DL measurement information and the specified SRS is the first antenna panel.

[0169] Furthermore, determining that the panel corresponding to the panel information not included in the DL measurement information is the first antenna panel means: the panel corresponding to the panel information not included in the DL measurement information except for the measurement information for measuring SSB / CSI-RS for BM is the first antenna panel; specifying that the panel corresponding to the panel information not included in the SRS is the first antenna panel means: specifying that the panel corresponding to the panel information not included in the SRS except for the SRS for BM is the first antenna panel.

[0170] In the above-mentioned method 2, the terminal device can also be indirectly informed of the first antenna panel to be turned off through panel information that is not included or implicitly indicated in the target information. The target message is information for receiving configuration data or control information of the network side device.

[0171] Specifically, the target information includes TCI state, and the panel information that is not included or implicitly indicated in the target information refers to: the panel information that is not included or implicitly indicated in the TCI state. Among them, the panel information implicitly indicated by the TCI state refers to: the panel information corresponding to the RS in the TCI state, and the panel information can be the receiving panel corresponding to the RS in the most recent beam report. If the beam report reports the results of multiple panels receiving the RS, then it refers to the best panel (with the highest RSRP and SINR) in the reported results.

[0172] Step 2: The terminal device turns off the first antenna panel (the specific implementation process can refer to the above embodiment and is not further limited here).

[0173] In another embodiment, the process of determining the first antenna panel by the user is as follows:

[0174] Step 3, the terminal device notifies the network side device that the first antenna panel of the terminal device needs to be turned off;

[0175] In step 3, notification method 1 and notification method 2 are included, wherein method 1 is that the network side device explicitly notifies the terminal device to turn off the first antenna panel through display signaling; method 2 is that the network side device indirectly notifies the terminal device to turn off the first antenna panel.

[0176] In the above notification mode 1, the display signaling may include: physical layer signaling, medium access control signaling or other high-layer signaling. The display signaling may be notified to the first antenna panel in any of the following ways:

[0177] a) Tell which panels are open

[0178] b) Tell which panels are closed

[0179] c) Tell all panels whether they are open or closed

[0180] d) Tell which panels are changed from open to closed or from closed to open.

[0181] In the above notification method 2, for DL ​​BM, the terminal device can indirectly notify the panel information through beam report; for UL BM, the terminal device can notify the panel information through SRS.

[0182] Specifically, for DL ​​BM, it may be that all beam reports of this or N BMs indicate that a certain panel is poor; it may also be that all beam reports of this or N BMs do not contain information about a certain panel. In this embodiment, at least one beam measurement result corresponding to a panel is reported. The above N times may be N times in M ​​consecutive beam reports, where M and N may be configured by the network side device through physical layer signaling, medium access control signaling or other high-level signaling.

[0183] For UL BM, the terminal device can inform the first antenna panel through the panel information that is not included or implied in the SRS sent this time or N times. Specifically, the panel information can be the resource set of SRS for BM, or the spatialRelationInfo of Other SRS. In this embodiment, at least one SRS corresponding to a panel must be sent. The above N times can be N times in the beam report reported M times in a row, where M and N can be configured by the network side device through physical layer signaling, medium access control signaling or other high-level signaling.

[0184] Step 4: The terminal device turns off the first antenna panel (the specific implementation process can refer to the above embodiment and is not further limited here).

[0185] In yet another embodiment, the process of determining the first antenna panel based on time is as follows:

[0186] Step 5: Determine a first antenna panel based on uplink and / or downlink transmission.

[0187] In step 5, the antenna panel that has no uplink transmission for a period of time can be determined as the first antenna panel; the antenna panel that has no downlink transmission for a period of time can be determined as the first antenna panel; and the antenna panel that has neither uplink transmission nor downlink transmission for a period of time can be determined as the first antenna panel.

[0188] For example, for uplink transmission, if the terminal device uses a certain panel for uplink transmission within a detection period, the panel is in the open state; if the terminal device does not use the panel for uplink transmission within a detection period, then both the network side device and the terminal device believe that the panel is in the closed state, and the terminal device will close the panel.

[0189] Wherein, the uplink transmission includes data information and control information, and the setting of the above detection time can be controlled by RRC, MACCE or DCI.

[0190] Furthermore, in an optional solution, special uplink transmission may be considered, and the special uplink transmission includes using the panel to send SRS for BM. Specifically, the SRS for BM may be aperiodic. Using the panel to send SRS for BM may specifically mean that the terminal device uses the panel to send all or some types of aperiodic SRS for BM.

[0191] When the above-mentioned special uplink transmission occurs, the terminal device and the network-side device may consider that the terminal device does not use the panel for uplink transmission.

[0192] When the panel is in the closed state, the terminal device can temporarily use the panel to complete the task of special uplink transmission, and then the terminal device closes the panel. In this embodiment, the network side device needs to consider that it takes time to temporarily open the panel and provide sufficient delay. In addition, the terminal device can tell the network side device how much time it takes to open the panel; or the network side device defaults to the time required for a terminal device to open the panel.

[0193] It should be noted that in order to ensure normal communication, at least one panel of the terminal device is open. If all panels have no uplink transmission within a period of detection time, a default panel will remain open. The default panel can be the panel sent by PUCCH (for example, the panel corresponding to the spatial relation info corresponding to the minimum ID PUCCH in the Dedicated PUCCH resource); it can also be the panel corresponding to PUSCH transmission (the panel corresponding to the default beam of PUSCH scheduled by DCI 0-0); it can also be the most recently scheduled panel; it can also be the panel corresponding to the best beam.

[0194] For downlink transmission, if the terminal device uses a panel for downlink transmission within a detection period, the panel is in the open state; if the terminal device does not use the panel for downlink transmission within a detection period, then both the network side device and the terminal device believe that the panel is in the closed state, and the terminal device will close the panel.

[0195] Specifically, the network side device can instruct the terminal device to receive data or control information through the above-mentioned target information. The target information includes TCI state, and the panel information that is not included or implicitly indicated in the target information refers to: the panel information that is not included or implicitly indicated in TCIstate. Among them, the panel information implicitly indicated by TCI state refers to: the panel information corresponding to the RS in the TCI state, and the panel information can be the receiving panel corresponding to the RS in the most recent beam report. If the beam report reports the results of multiple panels receiving the RS, then it refers to the best panel (with the highest RSRP and SINR) in the reported results.

[0196] If the terminal device does not use a panel for downlink transmission within a detection period, then both the network side device and the terminal device consider that the panel is in a closed state, and the terminal device will close the panel. The above detection time setting can be controlled by RRC, MAC CE or DCI.

[0197] Furthermore, in an optional scheme, special downlink transmission may also be considered, and the special downlink transmission includes using the panel to receive SSB / CSI-RS for BM. Specifically, the SSB / CSI-RS for BM may be non-periodic, such as a non-periodic SSB / CSI-RS for BM with repetition set to "on" (repetition is "on", i.e., P1 or P3). Using the panel to receive SSB / CSI-RS for BM may specifically mean that the terminal device uses the panel to receive all types or some types of non-periodic SSB / CSI-RS for BM.

[0198] When the above-mentioned special downlink transmission occurs, the terminal device and the network-side device may consider that the terminal device does not use the panel for uplink transmission.

[0199] When the panel is in the closed state, the terminal device can temporarily use the panel to complete the task of special downlink transmission, and then the terminal device closes the panel. In this embodiment, the network side device needs to consider that it takes time to temporarily open the panel and provide sufficient delay. In addition, the terminal device can tell the network side device how much time it takes to open the panel; or the network side device defaults to the time required for a terminal device to open the panel.

[0200] It should be noted that in order to ensure normal communication, at least one panel of the terminal device is in an open state. If all panels have no downlink transmission within a period of detection time, a default panel will remain open. The default panel can be a panel for PDCCH reception (for example, the panel corresponding to CORESET#0 or all panels for PDCCH reception); it can also be a panel corresponding to PDSCH reception; it can also be a recently scheduled panel; it can also be a panel corresponding to the best beam.
