Description

Method, device and apparatus for sending information by user equipment and storage medium

Technical Field

The present invention relates to the field of wireless communications, and in particular, to a method, device, apparatus, and storage medium for transmitting information by a user equipment.

Background

The nr (new radio) system refers to a fifth Generation mobile communication system (5G) dominated by the third Generation Partnership Project (3 GPP), where the available duration and lifetime of a battery of a User Equipment (UE) are important aspects of the User experience.

The method includes that the UE starts Physical Downlink Control Channel (PDCCH) monitoring (PDCCH monitoring), the consumed electric quantity is large, the usable time and the service life of a UE battery are both adversely affected, and accordingly, the NR system introduces a function of skipping PDCCH monitoring (PDCCH skiping) at the UE side, so that the electric quantity consumption of the UE caused by starting the PDCCH monitoring is reduced.

However, the conventional technology does not consider how to perform processing when the UE needs to transmit a Scheduling Request (SR) in a PDCCH blanking scenario.

Disclosure of Invention

An object of the embodiments of the present invention is to provide a method, a device, an apparatus, and a storage medium for sending information by a user equipment.

The embodiment of the invention provides a method for sending information by user equipment, which comprises the following steps: receiving PDCCH skiping information; it is determined whether a scheduling request SR is transmitted during PDCCH blanking or whether data is transmitted on a configured grant CG based on the configuration information.

Optionally, the configuration information comprises first configuration information configured locally or received from the network device, which is set not to transmit the SR or the data.

Optionally, the configuration information comprises second configuration information configured locally or received from the network device, arranged to selectively transmit the SR or the data.

Optionally, the second configuration information includes a priority threshold of an SR allowed to be transmitted or a priority threshold of data allowed to be transmitted.

Optionally, the SR with the priority greater than or equal to the priority threshold is allowed to transmit, and the SR with the priority less than the priority threshold is not transmitted; or data with a priority greater than or equal to the priority threshold is allowed to be transmitted while data less than the priority threshold is not transmitted.

Optionally, transmission is allowed for an SR within the last m slots during PDCCH blanking, where m is an integer greater than or equal to 1.

Optionally, m is set by a protocol or configured by a network device.

The embodiment of the present invention further provides a user equipment, which includes a memory and a processor, where the memory stores computer instructions executable on the processor, and the processor executes the computer instructions to perform any of the steps of the method described above.

The embodiment of the invention also provides a storage medium, wherein computer instructions are stored on the storage medium, and when the computer instructions are operated, the steps of any one of the methods are executed.

An embodiment of the present invention further provides a user equipment, including: a receiving module adapted to receive PDCCH skiping information; a determining module adapted to determine whether to transmit an SR during PDCCH clipping or whether to transmit data on a configured grant CG based on the configuration information.

Optionally, m is set by a protocol or configured by a network device.

Compared with the prior art, the technical scheme of the embodiment of the invention has the beneficial effect.

For example, the prior art does not consider that, in a PDCCH skiping scenario, if the UE transmits an SR, the UE may continue to monitor the PDCCH, thereby increasing power consumption of the UE. In an embodiment of the present invention, whether to transmit an SR during a PDCCH blanking period or whether to transmit data on a Configured Grant (CG) is determined based on configuration information, so that the UE may not transmit the SR or the data, or may selectively transmit or not transmit the SR or the data. Specifically, the UE may not send the SR or the data, so that on one hand, starting PDCCH monitoring after sending the SR may be avoided, which reduces power consumption of the UE, and on the other hand, the network device may reduce the number of UEs that need to be scheduled in a case of a heavy load; the UE can also determine whether to transmit the SR or the data based on the priority, which can enable the network equipment to reduce the number of the UE needing scheduling or reduce the power consumption of the UE on the one hand, and can also enable the data with higher priority to be transmitted preferentially to avoid increasing the time delay for transmitting the data on the other hand.

The module may be stored in a storage medium and includes instructions for causing a computer device (which may be a personal computer, a server, or a network-connected device) to perform steps of a method associated with embodiments of the present invention.

In order to make the objects, features and advantages of the embodiments of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1, an embodiment of the present invention provides a method 100 for a user equipment to send information, which may include:

s110, receiving PDCCH skiping information;

s120, determining whether to transmit an SR during the PDCCH skiping or whether to transmit data on a configured grant cg (configured grant) based on the configuration information.

In the execution of step S110, the UE receives PDCCH skiping information transmitted by the network device.

Specifically, the network device may send PDCCH skiping Information based on the reason that the UE saves power or the network device has a high load, and the PDCCH skiping Information may be sent by the network device through Downlink Control Information (DCI) on the PDCCH.

For example, the UE receives PDCCH clipping information sent by the network device in a time slot n, and knows that PDCCH monitoring is skipped in a period of time, where the period of time is a PDCCH clipping duration, and the period of time may be an explicit time length, for example, 10ms or a time length corresponding to k time slots, and may be preconfigured by the network device through DCI indication or through Radio Resource Control (RRC) signaling, where n and k are integers greater than or equal to 1.

In the execution of step S120, the UE determines whether to transmit an SR or whether to transmit data on the CG during the PDCCH skiping based on the configuration information.

In some embodiments of the invention, it relates to whether or not to send an SR.

The UE is in an RRC connected state in the serving cell, and the serving cell generally configures a search space and a detection opportunity for PDCCH detection for the UE. The UE may establish one or more services.

One UE may configure one or more SRs, and the network device may configure one or more logical channels of the UE corresponding to one SR configuration (SR configuration).

In a particular embodiment, the configuration information comprises first configuration information arranged to not transmit the SR during the PDCCH blanking period. The first configuration information may be local configuration information of the UE (for example, configured in a protocol setting manner), or may be configured by the network device and sent to the UE. In another embodiment, the network setup may indicate the reason for PDCCH clipping in PDCCH clipping DCI, e.g. because the network load is high or for UE power saving reasons. For example, when the network sets a reason that the network load is high, the UE does not transmit a scheduling request during PDCCH skiping.

If there is an SR that needs to be transmitted during the PDCCH blanking period, the UE may set it to a waiting (pending) state, and may transmit the SR after the time of the PDCCH blanking is over.

The UE does not send the SR in the PDCCH clipping period based on the first configuration information, so that the UE can keep the PDCCH clipping state, the PDCCH monitoring is prevented from being started after the SR is sent, and the power consumption of the UE is reduced; in addition, the UE is only directly set not to transmit the SR in the PDCCH skiping period, and the SR does not need to be selectively transmitted through a related algorithm, so that the processing process of the UE is simplified, and the power consumption is further reduced; in addition, under the condition of more loads, the network equipment reduces the number of UE needing scheduling, and is beneficial to self maintenance of the network.

In a particular embodiment, the configuration information comprises second configuration information arranged to selectively transmit the SR during a PDCCH blanking period. The second configuration information may be local configuration information of the UE (for example, configured in a protocol setting manner), or may be configured by the network device and sent to the UE.

The UE may determine whether to transmit the SR during the PDCCH skiping based on the second configuration information.

The network device may indicate its priority when configuring logical channels of the UE. When one logical channel has data to be transmitted uplink, if other logical channels do not have uplink data or the logical channel with high priority does not have uplink data at this time, the UE may trigger the SR corresponding to the logical channel, where the priority of the SR is the priority of the logical channel triggering the SR; for a scenario where multiple logical channels correspond to one SR, if the 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.

Specifically, the second configuration information includes a priority threshold of the SR allowed to be transmitted.

For example, in the second configuration information, the SRs are divided into an SR with a high priority and an SR with a low priority, the SR with the high priority corresponds to a flag of "transmit", and the SR with the low priority corresponds to a flag of "not transmit", wherein the SR with the high priority may include an SR corresponding to a media Access Control Element (MAC CE) of secondary cell Beam Failure Recovery (BFR) and an SR triggered by a high priority logical channel. Therefore, when an SR needs to be transmitted, the UE may determine whether to transmit the SR according to the priority of the SR. If the SR needing to be transmitted has high priority, namely is greater than or equal to the priority threshold of the SR allowed to be transmitted, transmitting the SR to avoid scheduling delay caused by postponing the transmission of the SR; if the SR has a low priority, that is, is lower than the priority threshold of the SR allowed to be transmitted, the SR is not transmitted (the UE may set it to a pending state, and may transmit the SR after the PDCCH blanking time is over), and generally, the delay requirement of the logical channel with the low priority is low, that is, the delay may be large.

For another example, in the second configuration information, the priority of the SR is sequentially divided into several levels according to the level of the priority (for example, eight levels "0-7" with sequentially lower priorities, where 0 represents the highest priority), and a priority threshold (for example, level 4) is set; the SR with the priority greater than or equal to the priority threshold is transmitted (to avoid increasing the uplink scheduling delay of the SR), and the SR with the priority less than the priority threshold is not transmitted (the UE may set it to a pending state, and may transmit the SR after the PDCCH blanking time is over). The priority threshold may be configured locally by the UE (e.g., configured in a protocol setting), or may be configured by the network device and sent to the UE.

The UE selectively transmits the SR during the PDCCH blanking period based on the second configuration information, which may enable the network device to reduce the number of UEs that need to be scheduled or reduce power consumption of the UEs on the one hand, and may also enable the SR with a higher priority to be preferentially transmitted to avoid increasing a delay of transmitting the SR on the other hand.

In a specific implementation, for a transmitted SR (e.g., an SR transmitted by the UE based on the second configuration information), the network device may timely receive and process the SR transmitted by the UE, issue the UL Grant, allocate a transmission resource to the UE, and then the UE may upload data through a logical channel based on the transmission resource.

In a specific implementation, during a PDCCH clipping period, for an SR that needs to be sent, if the sending time of the SR is located in the last m slots of the PDCCH clipping period, the SR may be sent, where a value of m depends on a processing time of a network device, a UE sends the SR in the last small time period of the PDCCH clipping period, after the network device receives the SR, the network device needs a certain time to process the SR, and if the network device allocates an uplink transmission resource for the UE, sending a downlink control signaling is located right after the UE recovers to monitor the PDCCH, which does not affect power consumption of the UE, and can also reduce transmission delay of data, where m may be an integer greater than or equal to 1, such as 1, 2, or 3.

m can be preset by the network equipment and sent to the UE; m may also be preset at the UE according to the protocol.

In other embodiments of the invention, it relates to whether data is sent over the configured, authorized CG.

The network equipment can pre-configure zero, one or more CG and logic channels mapped to the CG, and send the logic channels to the UE; the CGs may be respectively configured based on the serving cell.

In a particular embodiment, the configuration information comprises first configuration information arranged not to transmit data on the CG during the PDCCH blanking period. The first configuration information may be local configuration information of the UE (for example, configured in a protocol setting manner), or may be configured by the network device and sent to the UE. If there is data that can be transmitted over the CG during the PDCCH blanking period, the UE may set it to a waiting (pending) state, and transmit the data in the slot corresponding to the next CG after the PDCCH blanking period ends.

The UE does not transmit data on the CG in the PDCCH clipping period based on the first configuration information, so that the UE can keep the PDCCH clipping state, the PDCCH monitoring is prevented from being started after the data is transmitted, and the power consumption of the UE is reduced; in addition, the UE is only directly set not to transmit data on the CG in the PDCCH skiping period, and the data does not need to be selectively transmitted through a related algorithm, so that the processing process of the UE is simplified, and the power consumption is further reduced; furthermore, the network device reduces the number of UEs that need to be scheduled in the case of a high load.

In a particular embodiment, the configuration information comprises second configuration information arranged to selectively transmit data on the CG during a PDCCH blanking period. The second configuration information may be local configuration information of the UE (for example, configured in a protocol setting manner), or may be configured by the network device and sent to the UE.

The UE may determine whether to transmit data on the CG during the PDCCH skiping based on the second configuration information.

The network device may indicate its priority when configuring the logical channel. The network device may configure a logical channel mapped at the CG, i.e., data of the logical channel may be transmitted through the CG.

Specifically, the second configuration information includes a priority threshold of data allowed to be transmitted, which is referred to herein as data transmitted through the CG.

For example, the network device configures the priority of the logical channel mapped on the CG to a high priority and a low priority in advance; in the second configuration information, the logical channel of high priority corresponds to the flag of "transmission", and the logical channel of low priority corresponds to the flag of "no transmission". Therefore, if a logical channel to which data transmitted on the CG belongs is of high priority, the data may be transmitted through the CG during PDCCH skiping. If the logical channel priority to which the data transmitted on the CG belongs is low, the data is not transmitted (the UE may set it to a pending state and transmit it through the next CG after the PDCCH skiping time is over).

For another example, the network device configures the priority of the logical channel mapped on the CG to several levels (e.g., eight levels "0-7" with sequentially lower priorities, 0 representing the highest priority) sequentially divided according to the priority level, and sets a priority threshold (e.g., level 4); data on logical channels with a priority greater than or equal to the priority threshold is allowed to be transmitted through the CG during PDCCH skiping (to avoid increasing the delay in transmitting the data, e.g., data of a logical channel with a priority of 1 is allowed to be transmitted through the CG), and data on logical channels less than the priority threshold is not allowed to be transmitted through the CG during PDCCH skiping. The priority threshold may be configured locally by the UE (e.g., configured in a protocol setting), or may be configured by the network device and sent to the UE.

Data of a plurality of logical channels, each having a priority, may be transmitted simultaneously at one CG, with the highest priority among the priorities being compared with a priority threshold. If the highest priority is greater than or equal to the priority threshold, the UE may transmit the CG during PDCCH skiping for transmission of data for the logical channel and possibly other logical channels multiplexing the CG together; if the highest priority is less than the priority threshold, the UE does not transmit the CG during PDCCH cropping.

The UE selectively transmits data on the CG during the PDCCH blanking period based on the second configuration information, which may enable the network device to reduce the number of UEs that need to be scheduled or reduce power consumption of the UEs on the one hand, and may also enable data with higher priority to be preferentially transmitted to avoid increasing the delay of transmitting the data on the other hand.

The embodiment of the present invention further provides a user equipment, which includes a memory and a processor, where the memory stores computer instructions capable of running on the processor, and the processor executes any of the above steps of the method for sending information by the user equipment when executing the computer instructions.

The embodiment of the invention also provides a storage medium, on which the computer instructions are stored, and when the computer instructions are executed, the steps of any one of the above methods for sending information by the user equipment are executed.

In a particular implementation, the configuration information includes second configuration information configured locally or received from the network device, which is arranged to selectively transmit the SR or the data.

In a specific implementation, the second configuration information includes a priority threshold of an SR allowed to be transmitted or a priority threshold of data allowed to be transmitted.
