Optionally, direct terminal connection (Device to Device, D2D) communication may be performed between the terminal devices 120.

Optionally, the 5G system or 5G network may also be referred to as a New Radio (NR) system or NR network.

Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which are not limited in the embodiment of the present application.

It should be understood that the devices with communication functions in the network/system in the embodiments of the present application may be referred to as communication devices. Taking the communication system 100 shown in FIG. 1 as an example, the communication device may include a network device 110 and a terminal device 120 with communication functions, and the network device 110 and the terminal device 120 may be the specific devices described above, which will not be repeated here.

It should also be understood that the communication system 100 shown in FIG. 1 may also be a non-terrestrial communication network (Non-Terrestrial Network, NTN) system. Specifically, NTN generally uses satellite communication to provide communication services to ground users. In other words, the network device 110 in FIG. 1 may be a satellite. Compared with terrestrial cellular network communication, satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user's area. For example, general terrestrial communication cannot cover areas where communication equipment cannot be installed, such as oceans, mountains, and deserts, or areas where communication is not covered due to sparse population. Satellites can cover a larger ground, and satellites can orbit the earth, so in theory every corner of the earth can be covered by satellite communications. Secondly, satellite communications have greater social value. Satellite communication can be covered at a lower cost in remote mountainous areas, poor and backward countries or regions, so that people in these areas can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap with developed areas and promoting The development of these areas. Third, the satellite communication distance is long, and the communication cost has not increased significantly with the increase of the communication distance; finally, the stability of satellite communication is high, and it is not restricted by natural disasters.

Communication satellites are divided into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, and highly elliptical orbits according to their orbital heights. (High Elliptical Orbit, HEO) satellite and so on. The main research at this stage is LEO and GEO. Among them, the LEO satellite altitude ranges from 500km to 1500km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between users is generally less than 20ms. The maximum satellite viewing time is 20 minutes. The signal propagation distance is short, the link loss is small, and the transmission power requirement of the user terminal is not high; the GEO orbit height is 35786km, and the rotation period around the earth is 24 hours. The signal propagation delay of single-hop communication between users is generally 250ms. In order to ensure satellite coverage and increase the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover tens to hundreds of kilometers in diameter. Ground area.

It should be understood that the terms "system" and "network" in this article are often used interchangeably in this article. The term "and/or" in this article is only an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, exist alone B these three situations. In addition, the character "/" in this text generally indicates that the associated objects before and after are in an "or" relationship.

Based on the current NR standard, when the UE has uplink data arriving, but the UE does not have uplink resources for data transmission, the UE may need to go through the following 5 steps to send these data to the network, as shown in Figure 2.

S201: The UE sends an SR to request uplink resources from the gNB.

S202: The gNB receives the SR and knows that the UE needs uplink resources to transmit uplink data, but the gNB does not know how much uplink data the UE needs to send. Therefore, the gNB usually allocates enough PUSCH resources to the UE to send the BSR.

S203: The UE sends the BSR on the Physical Uplink Shared Channel (PUSCH) resource allocated by the gNB, so as to inform the gNB of the amount of data that the UE needs to send.

S204: The gNB allocates appropriate PUSCH resources to the UE for uplink data transmission according to the BSR information reported by the UE.

S205: The UE transmits uplink data on the PUSCH resource allocated by the gNB.

In the current solution, it may take a long time delay before the UE has uplink data until the UE sends these data to the network. This delay may affect the transmission of the service and thus the user experience.

Therefore, the embodiment of the present application proposes a method for transmitting data, which can reduce the service delay in the uplink scheduling process, thereby improving user experience.

FIG. 3 shows a schematic block diagram of a method 300 for transmitting data according to an embodiment of the present application. As shown in Figure 3, the method includes some or all of the following:

S310: The terminal device determines a target PUCCH resource from multiple physical uplink control channel PUCCH resources used to transmit the scheduling request SR according to the amount of data to be transmitted, where the multiple PUCCH resources correspond to multiple data volume intervals;

S320: The terminal device sends an SR on the target PUCCH resource.

Specifically, the terminal device may be configured with multiple PUCCH resources for transmitting SR through a protocol defined manner or a network device pre-configuration manner, and the multiple PUCCH resources may correspond to multiple data volume intervals. When the terminal device has uplink data arriving, it can select the data volume interval according to the amount of data to be transmitted, so as to use the PUCCH resource corresponding to the data volume interval to send the SR to the network device. When the network device detects the SR sent by the terminal device on a certain PUCCH resource, the network device can further find out the data volume interval corresponding to the PUCCH resource receiving the SR from the correspondence between the PUCCH resource and the data volume interval. Then the network device can roughly know how much uplink data the terminal device has to transmit, and then the network device can allocate appropriate PUSCH resources for the terminal device to transmit these uplink data.

In the related art, the terminal device enables the network device to learn the amount of uplink buffered data of the terminal device through the BSR, so that the network device can schedule the terminal device according to the data volume information provided by the terminal device. In order to save the BSR reporting overhead, the BSR is sent in a packet reporting manner. That is, each uplink logical channel corresponds to a logical channel group (Logic Channel Group, LCG), and multiple uplink logical channels can correspond to the same LCG, where the correspondence between LC and LCG can be configured by network equipment. Terminal equipment can report BSR based on LCG. In NR, each terminal equipment can support up to 8 LCGs.

BSR trigger conditions usually have the following types:

1. A higher priority uplink logical channel of the UE has uplink data arriving. In this case, a regular (Regular) BSR will be triggered.

2. The padding part of the uplink resource allocated to the UE after carrying other uplink data can carry the BSR Medium Access Control Control Element (MAC CE), and in this case, a padding BSR will be issued.

3. The retransmission BSR timer retxBSR-Timer times out, and there is currently at least one uplink logical channel with uplink data to be sent, at this time, a Regular BSR is triggered.

4. Periodic BSR timer periodicBSR-Timer expires, it will trigger Periodic BSR.

If multiple uplink logical channels trigger the Regular BSR at the same time, each of these uplink logical channels will trigger a separate Regular BSR, and the BSR is carried by the BSR MAC CE.

If a certain uplink logical channel of a terminal device triggers a Regular BSR, but the terminal device does not have uplink resources for transmitting new data or the uplink resources allocated to the terminal device for transmitting new data cannot carry the uplink that triggers the Regular BSR For the data of the logical channel, the terminal device triggers SR.

From the point of view of SR trigger conditions, SR is triggered based on the uplink logical channel. For each uplink logical channel of the terminal device, the network device can choose whether to configure the PUCCH resource for transmitting SR for the uplink logical channel. In the case that an uplink logical channel triggers SR, if the network device just configures the uplink logical channel with PUCCH resources for transmitting SR, then the terminal device can use the PUCCH for transmitting SR corresponding to the uplink logical channel. SR is sent on the resource; otherwise, the terminal device can initiate random access.

Optionally, when all the uplink logical channels that trigger the Regular BSR of the terminal device are not configured with PUCCH resources for transmitting the SR, the terminal device will initiate a random access procedure.

Optionally, in the embodiment of the present application, the terminal device may be configured with multiple PUCCH resources for transmitting SR, and the multiple PUCCH resources may be respectively configured for at least one uplink logical channel of the terminal device, if at least one of the terminal devices The uplink logical channel is configured with PUCCH resources. For any logical channel in the at least one uplink logical channel, multiple PUCCH resources can be configured, that is, one uplink logical channel is configured with one PUCCH resource group, The multiple PUCCH resources configured by the terminal device may be composed of PUCCH resources included in at least one PUCCH resource group corresponding to at least one uplink logical channel. Among the multiple PUCCH resources included in any two PUCCH resource groups, some of the PUCCH resources may overlap, or may not overlap at all, or may completely overlap.

When the N uplink logical channels of the terminal device trigger regular BSR, the terminal device can determine the target PUCCH resource from the multiple PUCCH resources configured for the terminal device according to the amount of data to be transmitted on the N uplink logical channels for transmission SR. Specifically, the terminal device may determine the target PUCCH resource from the at least one PUCCH resource group according to the amount of data to be transmitted of the N uplink logical channels. The at least one resource group corresponds to at least one uplink logical channel configured with PUCCH resources for transmitting SR among the N uplink logical channels. For example, the terminal device is configured with 8 uplink logical channels, the identifiers of which are 0-7, respectively. The uplink logical channels 1 to 3 are respectively configured with a PUCCH resource group, and the current uplink logical channels 2 to 5 are triggered respectively With regular BSR, the terminal device can determine the target PUCCH resource from the two PUCCH resource groups corresponding to the uplink logical channels 2 and 3 according to the amount of data to be transmitted in the uplink logical channels 2 to 5.

Further, the terminal device may first determine at least one candidate PUCCH resource from each PUCCH resource group in the at least one PUCCH resource group according to the amount of data to be transmitted in the N uplink logical channels, and then, the terminal device then Among all candidate PUCCH resources determined in the at least one PUCCH resource group, a target PUCCH resource is determined. Since the PUCCH resources included in different PUCCH resource groups may overlap, the candidate PUCCH resource determined from each PUCCH resource group may be a PUCCH resource, then the determined PUCCH resource can be used as the target PUCCH resources to send SR. The candidate PUCCH resources respectively determined from each PUCCH resource group may also be multiple PUCCH resources, and the terminal device may further select one PUCCH resource from the determined multiple PUCCH resources as the target PUCCH resource to send the SR.

When the terminal device needs to select a PUCCH resource from multiple candidate PUCCH resources as the target PUCCH resource, the terminal device can use the PUCCH resource closest to the current time among the multiple candidate PUCCH resources as the target PUCCH resource; or, the terminal device The priority of the uplink logical channel corresponding to the multiple candidate PUCCH resources can also be determined separately, and a candidate PUCCH resource corresponding to the uplink logical channel with the highest priority can be used as the target PUCCH resource; or, the terminal device can also use the multiple candidate PUCCH resources as the target PUCCH resource. A PUCCH resource is randomly selected from the PUCCH resources as the target PUCCH resource. It should be noted that whether the PUCCH resource closest to the current time is selected as the target PUCCH resource or the candidate PUCCH resource corresponding to the uplink logical channel with the highest priority is selected as the target PUCCH resource are just examples, that is, the distance from the current The time domain interval or the priority of the uplink logical channel can only be used as a reference for selecting the target PUCCH resource from the candidate PUCCH resources.

Regarding the priority of the uplink logical channel as a reference for selecting the target PUCCH resource, the terminal device will select from each PUCCH resource group in at least one PUCCH resource group according to the amount of data to be transmitted in the N uplink logical channels. Before selecting at least one candidate PUCCH resource respectively, since the at least one PUCCH resource group corresponds to at least one uplink logical channel, the terminal device can sort the priority of the at least one uplink logical channel, and optionally, the terminal device only needs to prioritize A candidate PUCCH resource is selected from a PUCCH resource group corresponding to the uplink logical channel with the highest level, and the candidate PUCCH resource is used as the target PUCCH resource.

It should be noted that for the same uplink logical channel, the data volume intervals corresponding to different PUCCH resources may partially overlap. If the data volume to be transmitted happens to be in the common overlapping area of multiple data volume intervals, The terminal device can then use multiple PUCCH resources corresponding to the multiple data volume intervals as candidate PUCCH resources. Alternatively, for the same uplink logical channel, the data volume interval corresponding to each PUCCH resource included in a PUCCH resource group corresponding to it is different, so for a data volume to be transmitted, it is only possible A candidate PUCCH resource is selected from a PUCCH resource group corresponding to the uplink logical channel. Optionally, for an uplink logical channel, the data volume interval corresponding to each PUCCH resource included in the corresponding PUCCH resource group may be divided by some thresholds, and these thresholds may be sorted in ascending order, Combine two groups of data into a data volume interval. For example, assuming that a PUCCH resource group corresponding to an uplink logical channel includes M PUCCH resources, the M data volume intervals corresponding to the M PUCCH resources can be divided by (M-1) thresholds, which are th1, ..., thM -1. That is, the data amount interval corresponding to PUCCH resource 1 can be [0, th1), the data amount interval corresponding to PUCCH resource 2 can be [th1, th2), and the data amount interval corresponding to PUCCH resource 3 can be [th2, th3),... , The data volume interval corresponding to PUCCH resource M can be [th(M-1), infinite). Optionally, for an uplink logical channel, the data volume interval corresponding to each PUCCH resource included in the corresponding PUCCH resource group may be configured by the network device, or may be predefined, as implemented in this application This example does not constitute a limitation.

Alternatively, the terminal device may also directly determine the target PUCCH resource from the at least one PUCCH resource group based on the amount of data to be transmitted on at least one logical channel that both triggers the Regular BSR and is configured with PUCCH resources. The embodiments of the application do not constitute a limitation on this.

Specifically, the terminal device may determine at least one candidate PUCCH resource from each PUCCH resource group in the at least one PUCCH resource group according to the following manner.

Manner 1: Since at least one uplink logical channel of the terminal device is configured with PUCCH resources for transmitting SR, that is, the at least one uplink logical channel corresponds to at least one PUCCH resource group, and the at least one uplink logical channel individually triggers regular BSR The terminal device may determine at least one PUCCH resource from a corresponding PUCCH resource group according to the amount of data to be transmitted in each uplink logical channel in the at least one uplink logical channel. Optionally, when the terminal device selects at least one candidate PUCCH resource from each PUCCH resource group, the terminal device can select one PUCCH resource from all the candidate PUCCH resources to indicate the amount of data to be transmitted for the uplink logical channel corresponding to the PUCCH resource , And the network device allocates the PUSCH to the terminal device according to the data volume interval corresponding to the PUCCH resource, and the terminal device can select the data of the corresponding data volume to upload as needed, regardless of whether the data is the uplink logical channel corresponding to the PUCCH resource that sends the SR The data to be transferred is available. Optionally, when the terminal device selects at least one candidate PUCCH resource from each PUCCH resource group, the terminal device may further determine a PUCCH resource as the target PUCCH from the at least one candidate PUCCH resource selected from each PUCCH resource. Resource, that is, the terminal device can respectively determine a corresponding PUCCH resource from each PUCCH resource group as the target PUCCH resource. For example, assuming that there are a total of 3 uplink logical channels configured with a PUCCH resource group, and the 3 uplink logical channels individually trigger a regular BSR, the terminal device can use the corresponding PUCCH according to the amount of data to be transmitted. One PUCCH resource is determined as the target PUCCH resource in the resource group, that is, three PUCCH resources are determined as the target PUCCH resource. The terminal device can send an SR on the three PUCCH resources. When the terminal device receives the data on the three PUCCH resources, In SR, the PUSCH resource for transmitting uplink data can be allocated to the terminal device according to the sum of the data volume intervals corresponding to the three PUCCH resources.

Manner 2: The terminal device may first sort the priorities of the above N uplink logical channels, and select the amount of data to be transmitted of the uplink logical channel with the highest priority from each PUCCH resource group in at least one PUCCH resource group. The basis of the candidate PUCCH resource. That is to say, assuming N=4, the identifiers are 0 to 3, the identifier of the uplink logical channel with the highest priority is 2, the amount of data to be transmitted for the uplink logical channel is A, and the at least one PUCCH resource group is 2 PUCCHs The resource groups are PUCCH resource group 1 and PUCCH resource group 2. The terminal device can select at least one candidate PUCCH resource from PUCCH resource group 1 and at least one candidate PUCCH from PUCCH resource group 2 according to the amount of data to be transmitted A Resources. Since the PUCCH resources included in the PUCCH resource group 1 and the PUCCH resources included in the PUCCH resource group 2 may be the same or different, if they are the same, the candidate PUCCH resources respectively selected from the two PUCCH resource groups may be the same; if they are different, then The candidate PUCCH resources respectively selected from the two PUCCH resource groups may be different. At this time, for the network device, the network device only needs to allocate an appropriate PUSCH for the uplink data volume interval corresponding to the PUCCH resource that receives the SR, and does not need to distinguish whether the PUSCH resource is allocated to which uplink logical channel of the terminal device. Which uplink logical channel to transmit the data to be transmitted can be determined by the terminal device.

Manner 3: The terminal device may first add the amount of data to be transmitted for the above N uplink logical channels, and use the sum of the amount of data to be transmitted for the N uplink logical channels as each PUCCH from at least one PUCCH resource group. The basis for selecting candidate PUCCH resources in the resource group. That is to say, assuming N=4, the identifiers are 0 to 3, the sum of the amount of data to be transmitted for the 4 uplink logical channels is B, and the at least one PUCCH resource group is 2 PUCCH resource groups, respectively PUCCH resource groups 1 and PUCCH resource group 2, the terminal device may select at least one candidate PUCCH resource from PUCCH resource group 1 and at least one candidate PUCCH resource from PUCCH resource group 2 according to the amount of data B to be transmitted. Since the PUCCH resources included in the PUCCH resource group 1 and the PUCCH resources included in the PUCCH resource group 2 may be the same or different, if they are the same, the candidate PUCCH resources respectively selected from the two PUCCH resource groups may be the same; if they are different, then The candidate PUCCH resources respectively selected from the two PUCCH resource groups may be different. At this time, for the network device, the PUSCH allocated by the network device for the uplink data volume interval corresponding to the PUCCH resource receiving the SR may cause the terminal device to transmit the data to be transmitted on all the current uplink logical channels, which can greatly reduce the uplink scheduling process Time delay.

Optionally, in this embodiment of the application, the network device may configure at least one upstream bandwidth part (Bandwidth Part, BWP) for the terminal device. Then, for any upstream BWP, the network device may separately configure multiple parts for transmission. PUCCH resources of SR. In other words, the network device may configure N PUCCH resources for the uplink BWP1 and M PUCCH resources for the uplink BWP2, and N may be equal to or not equal to M. Further, the network device can configure a number to the terminal device through broadcast or radio resource control (Radio Resource Control, RRC) dedicated signaling. As long as the terminal device receives the number, it can know that each uplink logical channel is configured in the network device. The number of PUCCH resources on the BWP. For each uplink logical channel to be configured with PUCCH resources for transmitting SR, the network device can select the number of PUCCH resources broadcast by the network device from the N PUCCH resources on the uplink BWP1 and configure the uplink logical channel; from the uplink BWP2 Select the number of PUCCH resources broadcast by the network device among the M PUCCH resources to be allocated to the uplink logical channel.

When a network device broadcasts the number of PUCCH resources to a terminal device, the number of PUCCH resources configured for each uplink logical channel of different terminal devices is the same, but the number of PUCCH resources configured by different terminal devices on an uplink BWP is not necessarily identical. For example, the number of PUCCH resources broadcast by the network device is 2. UE1 has 2 uplink logical channels (LC): LC11 and LC12, LC11 is configured with PUCCH resource 1 and PUCCH resource 2 on an uplink BWP, and LC12 is configured with PUCCH resource 1 and PUCCH resource 3 on the same uplink BWP , Wherein the data volume interval corresponding to PUCCH resource 2 and PUCCH resource 3 can be the same, but can be used to allocate to different LCs of the UE. UE2 has two LCs: LC21 and LC22, LC21 is configured with PUCCH 4 and PUCCH 5 on an uplink BWP, and LC22 is configured with PUCCH 4 and PUCCH 5 on the same UL BWP.

Optionally, for the same uplink BWP of the terminal device, the network device configures PUCCH resources for at least one uplink logical channel, and the number of PUCCH resources corresponding to each uplink logical channel in the at least one uplink logical channel may be the same Or different. If the same, the network device may only need to configure the number of PUCCH resources for the uplink logical channel of a terminal. For all the uplink logical channels configured with PUCCH resources on the uplink BWP, the number of PUCCH resources configured is identical. If they are different, the network device needs to configure multiple PUCCH resource numbers for the uplink logical channel of a terminal.

Optionally, for the same uplink logical channel configured with PUCCH resources of the terminal device, the number of PUCCH resources corresponding to different uplink BWPs may be the same or different. In other words, when the network device configures PUCCH resources for each uplink logical channel, it can be associated with the uplink BWP, and the network device can configure a number of PUCCH resources for an uplink logical channel, so the terminal device can be on any BWP. It is determined that the number of PUCCH resources corresponding to the uplink logical channel is the same; the network device may also configure a number of PUCCH resources for one uplink logical channel for different BWPs. Then, the terminal device can respectively determine the number of PUCCH resources corresponding to the uplink logical channel on any BWP.

The configuration of PUCCH resources may include the following parameters: time domain resource location and resource index. Then, for any two PUCCH resources in a PUCCH resource group corresponding to an uplink logical channel, the time domain resource location can be the same but the resource index is different; it can also be the time domain resource location and the resource index is the same; or it can also be the time domain. The resource location and resource index are different. Wherein, the time domain resource location can be characterized by period and/or time offset.

It can be seen from the above description that the terminal device can receive the configuration information sent by the network device, specifically, it can include at least one of the configuration information of the uplink BWP, the configuration information of the uplink logical channel, and the configuration information of the SR. For example, the configuration information of the uplink BWP is used to indicate that at least one uplink BWP is configured for the terminal device, and for each uplink BWP, multiple PUCCH resources for transmitting SR are configured. For another example, the configuration information of the uplink logical channel may refer to, for each uplink logical channel of the terminal device, whether to configure the PUCCH resource for transmitting SR for the uplink logical channel can be selected. If the uplink logical channel is selected to configure PUCCH resources for transmitting SR, the number of PUCCH resources configured on each uplink BWP for the uplink logical channel may be N. For another example, the configuration information of the uplink logical channel may also refer to the uplink logical channel configured with PUCCH resources for transmitting SR for each terminal device, and the uplink logical channel is configured with N transmission SRs on the same uplink BWP. The PUCCH resources can respectively correspond to N data volume intervals.

Optionally, the terminal device may also obtain first information in advance, where the first information is used for the number of multiple PUCCH resources configured for the terminal device, and/or the correspondence between the PUCCH resource and the data volume interval. Then the terminal device can determine the target PUCCH resource from the multiple PUCCH resources according to the amount of data to be transmitted. Optionally, the first information may be predefined information, information broadcast by a system message, or information carried in RRC signaling.

The method of the embodiment of the present application is especially suitable for NTN, so that the terminal device can send the SR to let the network device know the rough uplink data transmission requirements of the terminal device, so that the network device can be scheduled to transmit uplink data as soon as possible. Reduce the uplink service delay.

The three specific embodiments provided by the present application will be described in detail below in conjunction with FIGS. 4 to 6.

Embodiment 1: The number of 1 SR resources configured on an uplink BWP of the uplink logical channel can be determined through network broadcast or a predefined manner. For all terminals in the cell, if SR resources are configured for the uplink logical channels of the terminals, the uplink logical channels of different terminals have the same number of SR resources on an uplink BWP.

1. The UE receives system messages (including UE1 and UE2) and obtains the following information:

1. When the network configures the uplink logical channel with PUCCH resources for transmitting SR, the network configures the number of PUCCH resources for transmitting SR on each uplink BWP for the uplink logical channel N_SR=3.

2. Two uplink data thresholds ul_data_th_1 and ul_data_th_2, where ul_data_th_1<ul_data_th_2. Through these two threshold configurations, the amount of uplink data can be divided into 3 levels according to the amount of data:

Uplink data volume level 1:0<uplink data volume<=ul_data_th_1

Uplink data volume level 2: ul_data_th_1<uplink data volume<=ul_data_th_2

Uplink data volume level 3: Uplink data volume>ul_data_th_2

2. UE1 and UE2 respectively receive network RRC configuration information, configure uplink BWP related parameters, uplink logical channel related parameters, and SR related parameters. specifically:

1. For UE1 and UE2, configure one uplink BWP respectively, and configure the same uplink BWP for these two UEs;

2. For UE1 and UE2, respectively configure three PUCCH resources for transmitting SR on the configured uplink BWP, and respectively indicate the uplink data volume level corresponding to each PUCCH resource.

3. For UE1 and UE2, respectively configure one uplink logical channel, and configure three PUCCH resources for transmitting SR for the uplink logical channel. The three PUCCH resources for transmitting SR configured for each uplink logical channel are the three PUCCH resources for transmitting SR configured for the UE on the uplink BWP in (2).

3. For UE1, if UE1 has uplink data arriving at a certain moment, a regular BSR is triggered, and UE1 does not have uplink resources for transmitting the initial transmission, then UE1 triggers SR. The current data volume of the UE1 is within the data volume range corresponding to the uplink data volume level 1, so the UE sends the SR on the PUCCH resource corresponding to the uplink data volume level 1 closest to the current time.

4. The network receives the SR sent by UE1, and according to the PUCCH resource location of the received SR, the network can learn that the data volume of the UE is the uplink data volume level1, and the network allocates appropriate PUSCH resources to the UE according to the data volume information.

5. If at a certain moment UE1 has uplink data arriving, and regular BSR is triggered, and UE1 does not have uplink resources for transmitting the initial transmission, then UE1 triggers SR. The current data volume of the UE1 is within the data volume range corresponding to the uplink data volume level3, so the UE sends the SR on the PUCCH resource corresponding to the uplink data volume level3 closest to the current time.

6. The network receives the SR sent by the UE1, and according to the PUCCH resource location of the received SR, the network can learn that the data volume of the UE is the uplink data volume level3, and the network allocates appropriate PUSCH resources to the UE according to the data volume information.

7. For UE2, when UE2 has uplink data arriving at a certain moment, regular BSR is triggered, and UE2 does not have uplink resources for transmitting the initial transmission, then UE2 triggers SR. The method for UE2 to select PUCCH resources to send SR according to the current data volume is the same as that of UE1. For example, SR is triggered at a certain moment, and the current data volume of UE2 is at level 3 or the SR is triggered at a certain time, and the current data volume of UE2 is at level 2. , I won’t repeat it here.

The schematic diagram of Example 1 is shown in FIG. 4.

Embodiment 2: The number of multiple SR resources configured on one uplink BWP of the uplink logical channel can be determined through network broadcast or a predefined manner. For all terminals in the cell, if SR resources are configured for the uplink logical channels of the terminals, the number of SR resources on one uplink BWP of the uplink logical channels of different terminals may be different.

1. When the network configures the uplink logical channel with PUCCH resources for transmitting SR, the network configures the number of PUCCH resources for transmitting SR on each uplink BWP for the uplink logical channel N_SR1=2, N_SR2=3 .

2. Two sets of upstream data volume thresholds:

The first set of thresholds corresponds to N_SR1=2, and includes one uplink data volume threshold ul_data_th_1_1. Through this 1 threshold configuration, the amount of uplink data can be divided into 2 levels according to the amount of data: uplink data amount level11:0<uplink data amount<=ul_data_th_1_1; uplink data amount level21: uplink data amount>ul_data_th_1_1.

The second set of thresholds corresponds to N_SR2=3 and includes two uplink data volume thresholds ul_data_th_1_2 and ul_data_th_2_2, where ul_data_th_1_2<ul_data_th_2_2. Through these two threshold configurations, the amount of uplink data can be divided into 3 levels according to the amount of data: uplink data amount level12:0<uplink data amount<=ul_data_th_1_2; uplink data amount level22: uplink_data_th_1_2<uplink data amount<= ul_data_th_2_2; Upstream data volume level32: Upstream data volume>ul_data_th_2_2.

1. Configure 1 uplink BWP, and configure 3 PUCCH resources for transmitting SR on the uplink BWP, and respectively indicate the uplink data volume level corresponding to each PUCCH resource.

2. Configure one uplink logical channel, and configure three PUCCH resources for transmitting SR for the uplink logical channel. The three PUCCH resources for transmitting SR configured for each uplink logical channel are the three PUCCH resources for transmitting SR configured for UE1 on the uplink BWP in (1).

2.2. UE2 receives network RRC configuration information, configures uplink BWP related parameters, uplink logical channel related parameters, and SR related parameters. specifically:

2. Configure one uplink logical channel, and configure two PUCCH resources for transmitting SR for the uplink logical channel. The two PUCCH resources used for transmitting SR for each uplink logical channel quality are the two PUCCH resources used for transmitting SR configured by UE2 on the uplink BWP in (1).

3. For UE1, if UE1 has uplink data arriving at a certain moment, a regular BSR is triggered, and UE1 does not have uplink resources for transmitting the initial transmission, then UE1 triggers SR. The current data volume of UE1 is within the data volume range corresponding to the uplink data volume level12, so UE1 sends the SR on the PUCCH resource corresponding to the uplink data volume level12 closest to the current time.

4. The network receives the SR sent by the UE1, and according to the PUCCH resource location of the received SR, the network can learn that the data volume of the UE is the uplink data volume level12, and the network allocates appropriate PUSCH resources to the UE according to the data volume information.

5. At a certain moment UE1 has uplink data arriving, which triggers Regular BSR, and UE1 does not have uplink resources for transmitting the initial transmission, then UE1 triggers SR. The current data volume of the UE1 is within the data volume range corresponding to the uplink data volume level32, so the UE sends the SR on the PUCCH resource corresponding to the uplink data volume level32 closest to the current time.

6. The network receives the SR sent by UE1. According to the PUCCH resource location of the received SR, the network can learn that the data volume of the UE is the uplink data volume level32, and the network allocates appropriate PUSCH resources to the UE according to the data volume information.

7. For UE2, when UE2 has uplink data arriving at a certain moment, regular BSR is triggered, and UE2 does not have uplink resources for transmitting the initial transmission, then UE2 triggers SR. The method for UE2 to select PUCCH resources to send SR based on the current data volume is the same as that of UE1. For example, SR is triggered at a certain moment, and the current data volume of UE2 is at level 11 or SR is triggered at a certain time, and the current data volume of UE2 is at level 21. , I won’t repeat it here.

2. Two uplink data thresholds ul_data_th_1_1 and data_th_2_1, where ul_data_th_1_1<ul_data_th_2_1. Through these two threshold configurations, the amount of uplink data can be divided into 3 levels according to the amount of data: uplink data amount level11:0<uplink data amount<=ul_data_th_1_1; uplink data amount level21:ul_data_th_1_1<uplink data amount<=ul_data_th_2_1; Upstream data volume level31: Upstream data volume>ul_data_th_2_1.

2. One uplink data volume threshold ul_data_th_1_2. Through this threshold configuration, the amount of uplink data can be divided into 2 levels according to the amount of data: uplink data amount level12:0<uplink data amount<=ul_data_th_1_2; uplink data amount level22: uplink data amount>ul_data_th_1_2.

3. For UE1, when UE1 has uplink data arriving at a certain moment, a Regular BSR is triggered, and UE1 does not have uplink resources for transmitting the initial transmission, then UE1 triggers SR. The current data volume of the UE1 is within the data volume range corresponding to the uplink data volume level 11. Therefore, the UE sends the SR on the PUCCH resource corresponding to the uplink data volume level 11 closest to the current time.

4. The network receives the SR sent by the UE1, and according to the PUCCH resource location of the received SR, the network can learn that the data volume of the UE is the uplink data volume level 11, and the network allocates appropriate PUSCH resources to the UE according to the data volume information.
