[0002] In existing technologies, for downlink transmission of services within a specific cycle, the network needs to configure multiple downlink transmission resources in each cycle because data arrival times may vary. The terminal then needs to receive all downlink transmissions and provide relevant feedback information. However, not all of these multiple downlink transmission resources actually transmit data, leading to high terminal power consumption and wasted uplink feedback resources. Summary of the Invention

[0003] The purpose of this application is to provide a downlink transmission method, downlink transmission device, terminal, and network-side equipment, which can solve the problems of high power consumption and waste of uplink feedback resources caused by the terminal needing to receive all downlink transmissions and provide related feedback information.

[0007] Secondly, a downlink transmission device is provided for use in a terminal, comprising:

[0009] Thirdly, a downlink transmission method is provided, applied to network-side devices, including:

[0010] A first condition is pre-configured or a first indication is sent to the terminal.

[0030] The downlink transmission method, downlink transmission device, terminal, and network-side equipment provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0031] Figure 2 This is a flowchart of a downlink transmission method provided in an embodiment of this application, such as... Figure 2 As shown, the downlink transmission method, applied to a terminal, includes the following steps:

[0032] Step 201: Ignore the first downlink resource and / or ignore the uplink feedback corresponding to the first downlink resource. The first downlink resource is a resource in the downlink semi-persistent resources configured by the network-side device. The first downlink resource is determined by a pre-configured first condition or a first indication information sent by the network-side device.

[0033] Here, ignoring the first downlink resource can be understood as not receiving the downlink channel of the first downlink resource, or as discarding the downlink data of the first downlink resource. Ignoring the uplink feedback corresponding to the first downlink resource can be understood as not sending the uplink feedback information corresponding to the first downlink resource to the network-side equipment.

[0034] Prior to this step, the network-side device may send a first indication message to the terminal. The terminal receives the first indication message sent by the network-side device, which instructs the terminal to ignore the first downlink resource and / or the uplink feedback corresponding to the first downlink resource. The network-side device may also pre-configure a first condition, which instructs the terminal to ignore the first downlink resource and / or the uplink feedback corresponding to the first downlink resource. This first condition can also be agreed upon through a protocol, i.e., pre-configured by the protocol.

[0035] Prior to this step, the network-side device can also send downlink semi-persistent resource configuration information to the terminal. The terminal receives the downlink semi-persistent resource configuration information sent by the network-side device. This downlink semi-persistent resource configuration information is used to configure downlink semi-persistent resources for the terminal, such as semi-persistent scheduling (SPS) resources. This downlink semi-persistent resource configuration information is, for example, SPS configuration information.

[0036] It should be noted that the aforementioned first indication information may be carried in the aforementioned downlink semi-persistent resource configuration information, and the aforementioned downlink semi-persistent resource configuration information may also be carried in the aforementioned first indication information. The aforementioned first indication information and the aforementioned downlink semi-persistent resource configuration information may also be two independent pieces of information. This application embodiment does not limit this.

[0037] After receiving the downlink semi-persistent resource configuration information, the terminal can receive the corresponding downlink data channel and provide feedback on the uplink control channel when the downlink semi-persistent resource is activated. For example, the terminal can receive the Physical Downlink Shared Channel (PDSCH), or send a Hybrid Automatic Repeat reQuest (HARQ) feedback through the Physical Uplink Control Channel (PUCCH).

[0038] In addition, the terminal can determine the first downlink resource that can be ignored and / or the uplink feedback corresponding to the first downlink resource that can be ignored based on the first condition or the first indication information mentioned above. Thus, the terminal may not need to receive downlink channel data on the first downlink resource, or may discard downlink data on the first downlink resource, or may not need to send uplink feedback information corresponding to the first downlink resource.

[0039] In this embodiment, the terminal can ignore the first downlink resource or the uplink feedback corresponding to the first downlink resource in the downlink semi-persistent resources according to the pre-configured conditions or the indication information of the network-side device. In this way, the terminal does not need to receive all downlink transmissions or provide all downlink transmission feedback information, thereby saving the terminal's power and saving uplink feedback resources.

[0040] Optionally, the first downlink resource is a downlink resource used to receive specific downlink services.

[0041] For example, network-side devices can configure the downlink resources given by SPS Configuration-1 and SPS Configuration-2 for receiving downlink data for MBS Service-1.

[0042] Optionally, the first downlink resource is one or more downlink resources in a specific resource group.

[0043] Optionally, the specific resource group includes at least one of the following:

[0044] N downlink resources with the same resource transmission period, where N is an integer greater than or equal to 1;

[0045] M downlink resources with different resource transmission periods, where M is an integer greater than 1;

[0046] Downlink resources for K resource transmission cycles, where K is an integer greater than or equal to 1.

[0047] In this implementation, a specific resource group may include N downlink resources with the same resource transmission period. For example, SPS configuration-1 has a resource period of 10ms and is located in slot-1 (slot numbers are 1-10, each slot is 1ms). SPS configuration-2 has a resource period of 10ms and is located in slot-2. Therefore, the SPS resources in slot-1 and slot-2 can be configured as a specific SPS resource group. As another example, if SPS configuration-1 has a resource period of 10ms and is located in slot-1 and slot-2, then the SPS resources in slot-1 and slot-2 can also be configured as a specific SPS resource group.

[0048] A specific resource group can also include M downlink resources with different resource transmission periods. For example, the resource period of SPS configuration-1 is 10ms and the resource position is slot-1 (slot number is 1-10, each slot is 1ms). The resource period of SPS configuration-2 is 20ms and the resource position is slot-2. Then the resource period of SPS configuration-2 can be used as the period of the specific SPS resource group. That is, every 20ms, the SPS resources of slot-1 and slot-2 can be configured as the specific SPS resource group.

[0049] A specific resource group can also include downlink resources for K resource transmission cycles. For example, SPS resources for two cycles can be configured as a specific SPS resource group, such as the two SPS resources for cycle 1 and cycle 2 as the first SPS resource group, and the two SPS resources for cycle 3 and cycle 4 as the second SPS resource group.

[0050] Optionally, the resources of the specific resource group are configured through one or more resource configuration signaling methods.

[0051] When the first downlink resource is multiple downlink resources in a specific resource group, these multiple downlink resources can be configured through one or more resource configuration signaling. For example, one SPS configuration signaling can configure multiple SPS resources for one cycle, or multiple SPS configuration signaling can configure multiple SPS resources with the same (or different) cycle.

[0052] Optionally, the first indication information is used to indicate at least one of the following:

[0053] Ignore the first downlink resource;

[0054] The first downlink resource was preempted;

[0055] Ignore the uplink feedback corresponding to the first downlink resource;

[0056] The uplink feedback channel corresponding to the first downlink resource was preempted.

[0057] In this embodiment, the first indication information can be used to instruct the terminal to ignore the first downlink resource, that is, to ignore receiving a specific downlink data channel. For example, the first indication information can be downlink control information (DCI), which is used to instruct to ignore multiple SPS downlink data channels in one SPS resource group.

[0058] The first indication information can also be used to indicate that the first downlink resource has been preempted, that is, a specific downlink data channel has been preempted. For example, the first indication information can be DCI, which is used to indicate that multiple SPS downlink data channels in one SPS resource group have been preempted.

[0059] Regarding the aforementioned first indication information, the terminal can interpret it not only as meaning that the first downlink resource can be ignored based on the first indication information, but also as meaning that the uplink feedback corresponding to the first downlink resource can be ignored based on the first indication information. In other words, the aforementioned "first indication information for indicating that the first downlink resource should be ignored" is the same as "first indication information for indicating that the uplink feedback corresponding to the first downlink resource should be ignored".

[0060] Furthermore, the first indication information can also be used to indicate that uplink feedback corresponding to the first downlink resource is ignored. For example, the first indication information can be a DCI, which is used to indicate that uplink feedback corresponding to multiple SPS downlink data channels in one SPS resource group is ignored. The first indication information can also be used to indicate that the uplink feedback channel corresponding to the first downlink resource is preempted. For example, the first indication information can be a DCI, which is used to indicate that the uplink feedback channel corresponding to multiple SPS downlink data channels in one SPS resource group is preempted.

[0061] Optionally, the first indication information includes at least one of the following:

[0062] The quantity of the first downlink resource;

[0063] The time position of the first downlink resource.

[0064] In this embodiment, the first indication information can be used to indicate the number of downlink data channels that are ignored (or preempted). For example, if there are 5 PDSCH resources in one SPS resource group, the first indication information is used to indicate that 3 resources are ignored.

[0065] The first indication information can also be used to indicate the time position of ignored (or preempted) downlink data channels. For example, the first indication information is used to indicate that x consecutive periods of SPS resources are ignored from the indicated time position.

[0066] The first indication information can also be used to indicate the number and time position of the downlink data channels to be ignored (or preempted). For example, the first indication information is used to indicate ignoring three consecutive SPS resources starting from the indicated time position. Or, for example, if there are five PDSCH resources in an SPS resource group, the first indication information is used to indicate ignoring all subsequent SPS resources in the SPS resource group starting from the indicated time position.

[0067] Optionally, the first condition includes at least one of the following:

[0068] The first downlink resource is ignored at the pre-configured first time position;

[0069] Ignore the first downlink resource upon receiving the first data;

[0070] The first downlink resource is ignored upon receiving a first preset amount of data;

[0071] The first downlink resource is ignored if the first measured value of the measured signal is less than or equal to the first threshold value;

[0072] If the second measured value of the measured signal is greater than or equal to the second threshold value, the first downlink resource is ignored;

[0073] The uplink feedback of the first downlink resource is ignored at the pre-configured second time position;

[0074] Ignore the uplink feedback of the first downlink resource if no second data is received;

[0075] If the second preset amount of data is not received, the uplink feedback of the first downlink resource is ignored;

[0076] If the third measured value of the measured signal is less than or equal to the third threshold value, the uplink feedback of the first downlink resource is ignored;

[0077] If the fourth measured value of the measured signal is greater than or equal to the fourth threshold value, the uplink feedback of the first downlink resource is ignored.

[0078] In this implementation, the first condition may refer to ignoring the first downlink resource at a pre-configured time position, for example, ignoring n (e.g., 1) SPS downlink data channels every m (e.g., 3) periods.

[0079] The first condition can also refer to ignoring the receiving of a specific downlink data channel when specific data is received. For example, if the terminal successfully receives downlink data in one SPS resource group, the terminal can ignore the first downlink resource.

[0080] The first condition can also refer to ignoring the reception of a specific downlink data channel when a specific amount of data has been received. For example, if the terminal successfully receives x downlink data in one SPS resource group, the terminal can ignore the first downlink resource.

[0081] The first condition can also refer to the situation where the first measured value of the measured signal is less than or equal to a threshold value configured by the network-side equipment, in which case receiving a specific downlink data channel is ignored. The first measured value can be, for example, Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal to Interference plus Noise Ratio (SINR).

[0082] The first condition can also refer to ignoring the reception of a specific downlink data channel when the second measured value of the measured signal is greater than or equal to a threshold value configured by the network-side device. The second measured value could be, for example, the Received Signal Strength Indicator (RSSI), Channel Occupancy Rate (CR), or Channel Busy Ratio (CBR).

[0083] Regarding the aforementioned first condition, the terminal can interpret it not only as meaning that the first downlink resource can be ignored based on the first condition, but also as meaning that the uplink feedback corresponding to the first downlink resource can be ignored based on the first condition. In other words, the aforementioned "first condition for indicating the ignoring of the first downlink resource" is equivalent to "first condition for indicating the ignoring of the uplink feedback corresponding to the first downlink resource".

[0084] In addition, the first condition can also refer to ignoring the uplink feedback corresponding to a specific downlink data channel at a pre-configured time position. For example, ignoring the uplink feedback corresponding to n (e.g., 1) SPS downlink data channels every m (e.g., 3) cycles.

[0085] The first condition can also refer to ignoring the uplink feedback corresponding to a specific downlink data channel when no specific data is received. For example, if the terminal fails to receive downlink data in one SPS downlink data channel, the terminal can ignore sending the uplink feedback corresponding to that SPS downlink data channel.

[0086] The first condition can also refer to ignoring the reception of a specific downlink data channel when a specific number of data has not been received. For example, if the terminal does not receive x downlink data in one SPS resource group, the terminal can ignore the uplink feedback corresponding to the subsequent SPS downlink data channels in that SPS resource group.

[0087] The first condition can also refer to the situation where the third measured value of the measured signal is less than or equal to the threshold value configured by the network-side equipment, in which case the uplink feedback corresponding to the transmission of a specific downlink data channel is ignored. The third measured value can be, for example, RSRP, RSRQ, or SINR.

[0088] The first condition can also refer to the situation where the fourth measured value of the measured signal is greater than or equal to the threshold value configured by the network-side equipment, in which case the uplink feedback corresponding to the transmission of a specific downlink data channel is ignored. The fourth measured value can be, for example, RSSI, CR, or CBR.

[0089] Through the above implementation method, the terminal can ignore the reception of downlink data channel and the feedback transmission of uplink control channel in specific downlink resources. This saves the reception of downlink data channel and the transmission of uplink control channel when the network-side equipment has no data transmission or the channel quality is poor, and at the same time saves the terminal power.

[0090] In this embodiment, the terminal can ignore the first downlink resource or the uplink feedback corresponding to the first downlink resource in the downlink semi-persistent resources according to the pre-configured conditions or the indication information of the network side device. In this way, the terminal does not need to receive all downlink transmissions, nor does it need to provide feedback information for all downlink transmissions, thereby saving the terminal's power and saving uplink feedback resources.

[0091] It should be noted that the downlink transmission method provided in this application embodiment can be executed by a downlink transmission device, or by a control module within the downlink transmission device for executing the downlink transmission method. This application embodiment uses the execution of the downlink transmission method by a downlink transmission device as an example to illustrate the downlink transmission device provided in this application embodiment.
