[0001] The present invention relates to the field of wireless communications, and in particular to a method, equipment, device and storage medium for user equipment to send information. Background Art
[0002] NR (New Radio) system refers to the fifth generation mobile communication system (5G) led by the 3rd Generation Partnership Project (3GPP), in which the battery life and life of the user equipment (UE) are important aspects of the user experience.
[0003] The power consumed by UE when starting physical downlink control channel (PDCCH) monitoring is large, which has an adverse effect on the available time and life of the UE battery. Accordingly, the NR system introduces the function of skipping PDCCH monitoring on the UE side, thereby reducing the power consumption caused by starting PDCCH monitoring on the UE.
[0004] However, the prior art does not consider the problem of how to process when the UE needs to send a Scheduling Request (SR) in the PDCCH skipping scenario. Summary of the invention
[0005] The purpose of the embodiments of the present invention is to provide a method, device, apparatus and storage medium for sending information by user equipment.
[0006] An embodiment of the present invention provides a method for a user equipment to send information, comprising: receiving PDCCH skipping information; determining whether to send a scheduling request SR during PDCCH skipping or whether to send data on a configured authorized CG based on configuration information.
[0007] Optionally, the configuration information includes first configuration information that is locally configured or received from a network device, which is configured not to send an SR or data.
[0008] Optionally, the configuration information includes second configuration information that is locally configured or received from a network device, which is configured to selectively send the SR or the data.
[0009] Optionally, the second configuration information includes a priority threshold of an SR allowed to be sent, or a priority threshold of data allowed to be sent.
[0010] Optionally, SRs with a priority greater than or equal to a priority threshold are allowed to be sent, while SRs with a priority less than the priority threshold are not sent; or data with a priority greater than or equal to a priority threshold are allowed to be sent, while data with a priority less than the priority threshold is not sent.
[0011] Optionally, SRs in the last m time slots during PDCCH skipping are allowed to be sent, where m is an integer greater than or equal to 1.
[0012] Optionally, m is set by a protocol or configured by a network device.
[0013] An embodiment of the present invention further provides a user equipment, including a memory and a processor, wherein the memory stores computer instructions executable on the processor, and the processor executes the steps of any of the above methods when executing the computer instructions.
[0014] An embodiment of the present invention further provides a storage medium on which computer instructions are stored. When the computer instructions are executed, the steps of any of the above methods are executed.
[0015] An embodiment of the present invention also provides a user device, comprising: a receiving module, which is suitable for receiving PDCCH skipping information; a determining module, which is suitable for determining whether to send SR during PDCCH skipping or whether to send data on the configured authorized CG based on configuration information.
[0016] Optionally, the configuration information includes first configuration information that is locally configured or received from a network device, which is configured not to send an SR or data.
[0017] Optionally, the configuration information includes second configuration information that is locally configured or received from a network device, which is configured to selectively send the SR or the data.
[0018] Optionally, the second configuration information includes a priority threshold of an SR allowed to be sent, or a priority threshold of data allowed to be sent.
[0019] Optionally, SRs with a priority greater than or equal to a priority threshold are allowed to be sent, while SRs with a priority less than the priority threshold are not sent; or data with a priority greater than or equal to a priority threshold are allowed to be sent, while data with a priority less than the priority threshold is not sent.
[0020] Optionally, SRs in the last m time slots during PDCCH skipping are allowed to be sent, where m is an integer greater than or equal to 1.
[0021] Optionally, m is set by a protocol or configured by a network device.
[0022] Compared with the prior art, the technical solution of the embodiment of the present invention has beneficial effects.
[0023] For example, the prior art does not take into account that in the scenario of PDCCH skipping, if the UE sends an SR, the UE will continue to monitor the PDCCH, thereby increasing the power consumption of the UE. In an embodiment of the present invention, whether to send an SR during the PDCCH skipping period or whether to send data on a configured grant (Configured Grant, CG) is determined based on configuration information, so that the UE may not send an SR or data, or may selectively send or not send an SR or data. Specifically, it may include the UE not sending an SR or data, thereby, on the one hand, avoiding starting PDCCH monitoring after sending an SR, which reduces the power consumption of the UE, and on the other hand, the network device can reduce the number of UEs that need to be scheduled under heavy load; it may also include the UE determining whether to send an SR or data based on priority, which, on the one hand, can enable the network device to reduce the number of UEs that need to be scheduled or reduce the power consumption of the UE, and on the other hand, it can also enable data with a higher priority to be sent first to avoid increasing the delay in sending the data.

[0031] In the embodiment of the present invention, the storage medium includes various media that can store program codes, such as a USB flash drive, a mobile hard disk, a ROM, a RAM, a magnetic disk or an optical disk.
[0032] In the embodiments of the present invention, the device embodiments are only illustrative, for example, the division of modules is only a logical function division, and there may be other division methods in actual implementation. The modules may be stored in a storage medium, including several instructions for enabling a computer device (which may be a personal computer, a server, or a device connected to a network, etc.) to execute the steps of the relevant methods in the embodiments of the present invention.
[0033] In order to make the purpose, features and beneficial effects of the embodiments of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0034] like Figure 1 As shown, the embodiment of the present invention provides a method 100 for a user equipment to send information, which may include:
[0035] S110, receiving PDCCH skipping information;
[0036] S120: Determine whether to send an SR during the PDCCH skipping period or whether to send data on a configured grant CG (Configured Grant) based on the configuration information.
[0037] During the execution of step S110 , the UE receives PDCCH skipping information sent by the network device.
[0038] Specifically, the network device may send PDCCH skipping information based on UE power saving or a high load of the network device itself. The PDCCH skipping information may be sent by the network device through downlink control information (Downlink Control Information, DCI) on the PDCCH.
[0039] For example, the UE receives the PDCCH skipping information sent by the network device in time slot n, and learns to skip PDCCH monitoring for a period of time. The period of time is the duration of PDCCH skipping. This period of time can be a clear time length, such as 10ms, or it can be a time length corresponding to k time slots. It can be pre-configured by the network device through DCI indication or through Radio Resource Control (RRC) signaling, where n and k are both integers greater than or equal to 1.
[0040] During the execution of step S120, the UE determines whether to send an SR during the PDCCH skipping period or whether to send data on the CG based on the configuration information.
[0041] In some embodiments of the present invention, it is concerned whether to send an SR.
[0042] The UE is in RRC connected state in the serving cell, and the serving cell usually configures the search space and detection timing of PDCCH detection for the UE. The UE can establish one or more services.
[0043] A UE can be configured with one or more SRs, and a network device can configure one or more logical channels of the UE to correspond to an SR configuration.
[0044] In a specific embodiment, the configuration information includes first configuration information, which is configured not to send SR during PDCCH skipping. The first configuration information can be local configuration information of the UE (such as configured in a protocol setting), or can be configured by a network device and sent to the UE. Another implementation method is that the network setting can indicate the reason for PDCCH skipping in the PDCCH skipping DCI, such as because of high network load or for UE power saving. For example, when the network sets the reason for high network load, the UE does not send a scheduling request during PDCCH skipping.
[0045] If there is an SR that needs to be sent during the PDCCH skipping period, the UE can set it to a pending state and can send the SR after the PDCCH skipping time ends.
[0046] Based on the first configuration information, the UE does not send an SR during the PDCCH skipping period, which can enable the UE to maintain the PDCCH skipping state, thereby avoiding starting PDCCH monitoring after sending the SR, thereby reducing the power consumption of the UE; and, since the UE is only directly set to not send an SR during the PDCCH skipping period, without the need to selectively send an SR through a related algorithm, the processing process of the UE is simplified and the power consumption is further reduced; in addition, under heavy load conditions, the network equipment reduces the number of UEs that need to be scheduled, which is beneficial to the network's own maintenance.
[0047] In a specific embodiment, the configuration information includes second configuration information, which is configured to selectively send SR during PDCCH skipping. The second configuration information can be local configuration information of the UE (such as configured in a protocol setting), or can be configured by a network device and sent to the UE.
[0048] The UE may determine whether to send an SR during the PDCCH skipping period based on the second configuration information.
[0049] The network device can indicate the priority of the logical channel when configuring the UE. When a logical channel has data to be transmitted uplink, if other logical channels have no uplink data or the logical channel with a high priority has no uplink data, the UE can trigger the SR corresponding to the logical channel, and the priority of the SR is the priority of the logical channel that triggers the SR; for the scenario where multiple logical channels correspond to one SR, if multiple logical channels have uplink data at the same time, the priority of the triggered SR is the priority of the logical channel with the highest priority among the multiple logical channels.
[0050] Specifically, the second configuration information includes a priority threshold of the SR allowed to be sent.
[0051] For example, in the second configuration information, SRs are divided into SRs with high priority and SRs with low priority, the SRs with high priority correspond to the mark of "send", and the SRs with low priority correspond to the mark of "not send", wherein the SRs with high priority may include the SRs corresponding to the Medium Access Control Control Element (MAC CE) of the Beam Failure Recovery (BFR) of the secondary cell and the SRs triggered by the high priority logical channels. Therefore, when the SR needs to be sent, the UE can determine whether to send the SR according to the priority of the SR. If the SR to be sent has a high priority, that is, it is greater than or equal to the priority threshold of the SR allowed to be sent, the SR is sent to avoid scheduling delays caused by postponing the sending of the SR; if the SR has a low priority, that is, it is lower than the priority threshold of the SR allowed to be sent, the SR is not sent (the UE can set it to a pending state, and the SR can be sent after the PDCCH skipping time ends). Generally, the delay requirement of the low priority logical channel is low, that is, the delay can be large.
[0052] For another example, in the second configuration information, the priority of the SR is divided into several levels according to the priority level (such as eight levels "0-7" with decreasing priority, where 0 represents the highest priority), and a priority threshold is set (such as level 4); SRs with priorities greater than or equal to the priority threshold are sent (to avoid increasing the uplink scheduling delay of the SR), and SRs with priorities less than the priority threshold are not sent (the UE can set it to a pending state, and the SR can be sent after the PDCCH skipping time ends). The priority threshold can be configured locally by the UE (such as by using protocol settings), or it can be configured by the network device and sent to the UE.
[0053] The UE selectively sends an SR during the PDCCH skipping period based on the second configuration information. This can, on the one hand, enable the network device to reduce the number of UEs that need to be scheduled or reduce the power consumption of the UE. On the other hand, it can also enable SRs with higher priorities to be sent first to avoid increasing the delay in sending the SR.
[0054] In a specific implementation, for the SR sent (for example, the SR sent by the UE based on the second configuration information), the network device can promptly receive and process the SR sent by the UE, and issue a UL Grant to allocate transmission resources to the UE. Then, the UE can upload data through a logical channel based on the transmission resources.
[0055] In a specific implementation, during PDCCH skipping, for the SR that needs to be sent, if the sending time of the SR is within the last m time slots during the PDCCH skipping period, the SR can be sent, and the value of m depends on the processing time of the network device. The UE sends the SR within the last short period of time during the PDCCH skipping period. After the network device receives it, it takes a certain amount of time to process the SR. If the network device allocates uplink transmission resources to the UE, and sends the downlink control signaling just after the UE resumes monitoring the PDCCH, it not only does not affect the power consumption of the UE, but also can reduce the data transmission delay, wherein m can be an integer greater than or equal to 1, such as 1, 2 or 3.
[0056] m may be pre-set by the network device and sent to the UE; m may also be pre-set at the UE according to the protocol.
[0057] In some other embodiments of the present invention, it involves whether to send data on the configured authorized CG.
[0058] The network equipment can pre-configure zero, one or more CGs and the logical channels mapped to the CGs, and send them to the UE; the CGs can be configured separately based on the serving cell.
[0059] In a specific embodiment, the configuration information includes first configuration information, which is configured not to send data on the CG during the PDCCH skipping period. The first configuration information can be local configuration information of the UE (such as configured in a protocol setting), or it can be configured by a network device and sent to the UE. If there is data that can be sent on the CG during the PDCCH skipping period, the UE can set it to a pending state and send the data in the time slot corresponding to the next CG after the PDCCH skipping time ends.
[0060] Based on the first configuration information, the UE does not send data on the CG during the PDCCH skipping period, which can enable the UE to maintain the PDCCH skipping state, thereby avoiding starting PDCCH monitoring after sending the data, which reduces the power consumption of the UE; and, since the UE is only directly set to not send data on the CG during the PDCCH skipping period, there is no need to selectively send the data through a related algorithm, thereby simplifying the UE's processing process and further reducing power consumption; in addition, under heavy load conditions, the network equipment reduces the number of UEs that need to be scheduled.
[0061] In a specific embodiment, the configuration information includes second configuration information, which is configured to selectively send data on the CG during the PDCCH skipping period. The second configuration information can be local configuration information of the UE (such as configured in a protocol setting) or can be configured by a network device and sent to the UE.
[0062] The UE can determine whether to send data on the CG during the PDCCH skipping period based on the second configuration information.
[0063] The network device can indicate the priority of a logical channel when configuring it. The network device can configure a logical channel mapped to a CG, i.e., the data of the logical channel can be sent through the CG.
[0064] Specifically, the second configuration information includes the priority threshold of data allowed to be sent, which here refers to data sent through CG.
[0065] For example, the network device pre-configures the priority of the logical channel mapped to the CG as high priority and low priority; in the second configuration information, the high-priority logical channel corresponds to the "send" mark, and the low-priority logical channel corresponds to the "do not send" mark. Therefore, if the logical channel to which the data sent on the CG belongs is high priority, the data can be sent through the CG during PDCCH skipping. If the logical channel to which the data sent on the CG belongs is low priority, the data is not sent (the UE can set it to a pending state and send the data through the next CG after the PDCCH skipping time ends).
[0066] For another example, the network device pre-configures the priority of the logical channel mapped to the CG into several levels divided in order of priority (such as eight levels "0-7" with decreasing priority, 0 representing the highest priority), and sets a priority threshold (such as level 4); data on logical channels with a priority greater than or equal to the priority threshold are allowed to be sent through the CG during PDCCH skipping (to avoid increasing the delay in sending the data, such as data on logical channels with a priority of 1 are allowed to be sent through the CG), and data on logical channels with a priority less than the priority threshold are not allowed to be sent through the CG during PDCCH skipping. The priority threshold can be configured locally by the UE (such as configured by protocol settings), or it can be configured by the network device and sent to the UE.
[0067] On a CG, data of multiple logical channels can be sent simultaneously. These multiple logical channels have priorities respectively, and the highest priority among these priorities is compared with the priority threshold. If the highest priority is greater than or equal to the priority threshold, the UE can send the CG during PDCCH skipping to transmit data of the logical channel and other logical channels that may multiplex the CG together; if the highest priority is less than the priority threshold, the UE does not send the CG during PDCCH skipping.
[0068] Based on the second configuration information, the UE selectively sends data on the CG during the PDCCH skipping period. On the one hand, this can enable the network device to reduce the number of UEs that need to be scheduled or reduce the power consumption of the UE. On the other hand, it can also enable data with higher priority to be sent first to avoid increasing the delay in sending the data.
[0069] An embodiment of the present invention further provides a user equipment, including a memory and a processor, wherein the memory stores computer instructions executable on the processor, and when the processor executes the computer instructions, the steps of any of the above-mentioned methods for sending information by the user equipment are executed.
[0070] An embodiment of the present invention further provides a storage medium on which computer instructions are stored. When the computer instructions are executed, the steps of any of the above-mentioned methods for user equipment to send information are executed.

[0072] In a specific implementation, the configuration information includes first configuration information that is locally configured or received from a network device, which is configured not to send an SR or data.
[0073] In a specific implementation, the configuration information includes second configuration information that is locally configured or received from a network device, which is configured to selectively send an SR or data.
[0074] In a specific implementation, the second configuration information includes a priority threshold of an SR allowed to be sent, or a priority threshold of data allowed to be sent.

[0076] In a specific implementation, the SR in the last m time slots during the PDCCH skipping period is allowed to be sent, where m is an integer greater than or equal to 1.
[0077] In a specific implementation, m is set by a protocol or configured by a network device.
