Background

Based on the current New Radio (New Radio) standard, when uplink data arrives at the terminal, but the terminal does not have uplink resources for data transmission, the terminal generally needs to go through 5 steps to send the uplink data to the network. Specifically: a terminal needs to send a Scheduling Request (SR) for requesting uplink resources to a network; the network does not know how much uplink resources are needed by the terminal for transmitting uplink data, so the network allocates uplink resources for the terminal to send a buffer status report (Buffer Status Report, BSR); the terminal further transmits a BSR on the allocated uplink resource; therefore, the network can acquire the data size and allocate proper uplink resources for uplink data transmission to the terminal; and finally, the terminal transmits uplink data on uplink resources allocated by the network.

The existing uplink scheduling process may cause longer service delay, thereby affecting user experience.

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

It should be understood that a device having a communication function in a network/system in an embodiment of the present application may be referred to as a communication device. 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, where the network device 110 and the terminal device 120 may be specific devices described above, and are not described herein again; the communication device may also include other devices in the communication system 100, such as a mobility management entity (Mobility Management Entity, MME), a Serving Gateway (S-GW), a packet data Gateway (PDN Gateway), or the like, which is not limited in the embodiments of the present application.

It should also be appreciated that the communication system 100 shown in fig. 1 may also be a Non-terrestrial communication network (Non-Terrestrial Network, NTN) system, and in particular, NTN typically provides communication services to terrestrial users by way of satellite communications. That is, the network device 110 in fig. 1 may be a satellite. Satellite communications have many unique advantages over terrestrial cellular communications. First, satellite communications are not limited by the user region, for example, general land communications cannot cover areas where communication devices cannot be installed, such as oceans, mountains, deserts, etc., or communication coverage is not performed due to rarity of population, while for satellite communications, since one satellite can cover a larger ground, and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communications. And secondly, satellite communication has great social value. Satellite communication can be covered in remote mountain areas, poor and backward countries or regions with lower cost, so that people in the regions enjoy advanced voice communication and mobile internet technology, and the digital gap between developed regions is reduced, and the development of the regions is promoted. Again, the satellite communication distance is far, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into Low Earth Orbit (LEO) satellites, medium Earth Orbit (MEO) satellites, geosynchronous Orbit (Geostationary Earth Orbit, GEO) satellites, high elliptical Orbit (High Elliptical Orbit, HEO) satellites, and the like according to the Orbit heights. LEO and GEO are the main studies at the present stage. Wherein the LEO satellite has a height range of 500 km-1500 km and a corresponding orbit period of about 1.5 hours-2 hours. The signal propagation delay for single hop communications between users is typically less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the user terminal is not high; GEO orbit height is 35786km, rotation period around earth is 24 hours. The signal propagation delay for single hop communications between users is typically 250ms. In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form tens or hundreds of beams to cover the ground; a satellite beam may cover a ground area of several tens to hundreds of kilometers in diameter.

It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

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

S201, the UE sends an SR and requests uplink resources to the gNB.

S202: the gNB receives the SR, knows that the UE needs uplink resources for transmitting uplink data, but the gNB does not know how much uplink data the UE needs to transmit, so it is common practice for the gNB to allocate PUSCH resources to the UE that are sufficient for the UE to transmit BSR.

S203: the UE transmits a BSR on the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) resources allocated by the gNB, thereby informing the gNB of the size of the data amount that the UE needs to transmit.

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

S205: and the UE transmits uplink data on the PUSCH resources allocated by the gNB.

In the current scheme, a longer time delay may be required from the time when the UE has uplink data to the time when the UE transmits the data to the network, and the time delay may affect the transmission of the service, thereby affecting the user experience.

Therefore, the embodiment of the application provides a method for transmitting data, which can reduce the time delay of the service in the uplink scheduling process, so that the user experience can be improved.

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 fig. 3, the method includes some or all of the following:

s310, the terminal equipment determines target PUCCH resources from a plurality of physical uplink control channel PUCCH resources for transmitting a scheduling request SR according to the data volume to be transmitted, wherein the plurality of PUCCH resources correspond to a plurality of data volume intervals;

s320, the terminal device sends an SR on the target PUCCH resource.

Specifically, a plurality of PUCCH resources for transmitting SRs may be configured for the terminal device in a protocol-defined manner or in a network device preconfigured manner, and the plurality of PUCCH resources may correspond to a plurality of data amount intervals. When the terminal device has uplink data arrived, it can select which data volume interval is in according to the data volume to be transmitted, so as to send SR to the network device using PUCCH resource corresponding to the data volume interval. When the network device detects the SR sent by the terminal device on a certain PUCCH resource, the network device may 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, so that the network device may roughly know how much uplink data to be transmitted is available for the terminal device, and further the network device may allocate appropriate PUSCH resources for the terminal device to transmit the uplink data.

In the related art, the terminal device makes the network device acquire the uplink buffer data amount of the terminal device through the BSR, so that the network device can schedule the terminal device according to the data amount information provided by the terminal device. In order to save the cost of reporting the BSR, the BSR is sent by adopting a packet reporting mode. I.e. each uplink logical channel corresponds to one logical channel group (Logic Channel Group, LCG), a plurality of uplink logical channels may correspond to the same LCG, wherein the correspondence between LCs and LCGs may be configured by the network device. The terminal device may report BSR based on LCGs, and each terminal device may support up to 8 LCGs in the NR.

The triggering conditions of BSR are typically the following:

1. an uplink logical channel with higher priority for the UE has uplink data arriving, in which case a Regular BSR is triggered.

2. The Padding (Padding) portion of the uplink resources allocated to the UE after carrying other uplink data can carry a BSR medium access control unit (Medium Access Control Control Element, MAC CE), in which case a Padding BSR is sent out.

3. The retransmission BSR Timer retxBSR-Timer times out and there is currently at least one uplink logical channel for uplink data to be transmitted, at which time the Regular BSR is triggered.

4. The Periodic BSR Timer may trigger a Periodic BSR when the Periodic BSR-Timer expires.

If there are multiple uplink logical channels triggering a Regular BSR at the same time, each of these uplink logical channels triggers a separate Regular BSR, which is carried by the BSR MAC CE.

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

From the triggering condition of the SR, the SR is triggered based on an uplink logical channel. For each uplink logical channel of the terminal device, the network device may select whether PUCCH resources for transmitting SRs are configured for the uplink logical channel. If the network device configures PUCCH resources for transmitting SRs for an uplink logical channel in case that the SR is triggered by the uplink logical channel, the terminal device may transmit the SR on the PUCCH resources for transmitting SRs corresponding to the uplink logical channel; otherwise, the terminal device may initiate random access.

Alternatively, when all uplink logical channels of the terminal device triggering the Regular BSR are not configured with PUCCH resources for transmitting 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 a plurality of PUCCH resources for transmitting SR, where the plurality of PUCCH resources may be configured to at least one uplink logical channel of the terminal device, if at least one uplink logical channel of the terminal device is configured with PUCCH resources, any one of the at least one uplink logical channel may be configured with a plurality of PUCCH resources, that is, one uplink logical channel is configured with one PUCCH resource group, and the plurality of PUCCH resources configured by the terminal device may be configured with PUCCH resources included in at least one PUCCH resource group corresponding to the at least one uplink logical channel. The plurality of PUCCH resources included in any two PUCCH resource groups may have partial PUCCH resources overlapping, may not overlap at all, or may overlap at all.

When the N uplink logical channels of the terminal device trigger the regular BSR, the terminal device may determine, according to the data amounts to be transmitted of the N uplink logical channels, a target PUCCH resource from a plurality of PUCCH resources configured for the terminal device, to be used for transmitting the SR. Specifically, the terminal device may determine, according to the data amounts to be transmitted of the N uplink logical channels, a target PUCCH resource from the at least one PUCCH resource group. The at least one resource group corresponds to at least one uplink logical channel in the N uplink logical channels, in which PUCCH resources for transmitting SRs are configured. For example, the terminal device is configured with 8 uplink logical channels, the identities of which are respectively 0-7, wherein uplink logical channels 1-3 are respectively configured with one PUCCH resource group, and the current uplink logical channels 2-5 respectively trigger the regular BSR, so that 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 data amount to be transmitted of the uplink logical channels 2-5.

Further, 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 data amounts to be transmitted of the N uplink logical channels, and then determine the target PUCCH resource from all the candidate PUCCH resources determined in the at least one PUCCH resource group. Since there may be some overlap of PUCCH resources included in different PUCCH resource groups, the candidate PUCCH resource determined from each PUCCH resource group may be one PUCCH resource, and the determined one PUCCH resource may be used as the target PUCCH resource to transmit SR. And the candidate PUCCH resources respectively determined from each PUCCH resource group may be a plurality of PUCCH resources, then the terminal device may further select one PUCCH resource from the determined plurality of PUCCH resources as the target PUCCH resource to transmit the SR.

When the terminal equipment needs to select one PUCCH resource from a plurality of candidate PUCCH resources as a target PUCCH resource, the terminal equipment can use one PUCCH resource closest to the current time in the plurality of candidate PUCCH resources as the target PUCCH resource; or, the terminal device may further determine priorities of uplink logical channels corresponding to the plurality of candidate PUCCH resources, respectively, and use one candidate PUCCH resource corresponding to the uplink logical channel with the highest priority as a target PUCCH resource; alternatively, the terminal device may also randomly select one PUCCH resource from the plurality of candidate PUCCH resources as the target PUCCH resource. It should be noted that, whether one PUCCH resource closest to the current time is selected as the target PUCCH resource or one candidate PUCCH resource corresponding to the uplink logical channel with the highest priority is selected as the target PUCCH resource is merely an example, that is, the time domain interval from the current time or the priority of the uplink logical channel may be used only as one reference for selecting the target PUCCH resource from the candidate PUCCH resources.

For taking the priority of the uplink logic channel as a reference for selecting the target PUCCH resource, before the terminal device selects at least one candidate PUCCH resource from each PUCCH resource group in at least one PUCCH resource group according to the data amount to be transmitted of the N uplink logic channels, the terminal device may rank the priority of the at least one uplink logic channel because the at least one PUCCH resource group corresponds to the at least one uplink logic channel, and optionally, the terminal device only needs to select one candidate PUCCH resource from one PUCCH resource group corresponding to the uplink logic channel with the highest priority, and takes the candidate PUCCH resource 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 overlap partially, and if the data volume to be transmitted is just in the common overlapping region of the multiple data volume intervals, the terminal device may use the 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 the corresponding one of the PUCCH resource groups is different, so that for one data volume to be transmitted, only one candidate PUCCH resource can be selected from the corresponding one of the PUCCH resource groups of the uplink logical channel. Optionally, for an uplink logical channel, the data volume interval corresponding to each PUCCH resource included in a corresponding PUCCH resource group may be divided by some thresholds, and the thresholds may be ordered in order from small to large, and combined into a data volume interval two by two. For example, assuming that one PUCCH resource group corresponding to one uplink logical channel includes M PUCCH resources, M data volume sections corresponding to the M PUCCH resources may be divided by (M-1) thresholds, respectively, th1, …, thM-1. That is, the data amount interval corresponding to PUCCH resource 1 may be [0, th 1), the data amount interval corresponding to PUCCH resource 2 may be [ th1, th 2), the data amount interval corresponding to PUCCH resource 3 may be [ th2, th 3), …, and the data amount interval corresponding to PUCCH resource M may be [ th (M-1), infinity. Optionally, for one uplink logical channel, the data amount interval corresponding to each PUCCH resource included in one corresponding PUCCH resource group may be configured by a network device, or may be predefined, which is not limited by the embodiment of the present application.

Alternatively, the terminal device may also determine the target PUCCH resource from the at least one PUCCH resource group directly according to the amount of data to be transmitted of the at least one logical channel that triggers both the Regular BSR and is configured with PUCCH resources. The embodiments of the present application are not limited thereto.

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

Mode one: 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 each triggers a regular BSR separately, the terminal device may determine at least one PUCCH resource from the corresponding one PUCCH resource group according to the amount of data to be transmitted of each uplink logical channel in the at least one uplink logical channel, respectively. Optionally, when the terminal device selects at least one candidate PUCCH resource from each PUCCH resource group, the terminal device may select one PUCCH resource from all the candidate PUCCH resources to indicate an amount of data to be transmitted of an uplink logical channel corresponding to the PUCCH resource, and the network device allocates a PUSCH to the terminal device according to a data amount interval corresponding to the PUCCH resource, and the terminal device may select data of a corresponding amount of data to upload according to a need, whether the data is the data to be transmitted of the uplink logical channel corresponding to the PUCCH resource for transmitting SR or not. Alternatively, when the terminal device selects at least one candidate PUCCH resource from each PUCCH resource group, the terminal device may further determine one PUCCH resource as the target PUCCH resource from the at least one candidate PUCCH resource selected from each PUCCH resource, i.e. the terminal device may determine a corresponding one PUCCH resource as the target PUCCH resource from each PUCCH resource group. For example, assuming that a total of 3 uplink logical channels are respectively configured with one PUCCH resource group, and that the 3 uplink logical channels each individually trigger a regular BSR, the terminal device may determine, according to respective data amounts to be transmitted, one PUCCH resource from the corresponding one PUCCH resource group as a target PUCCH resource, that is, determine 3 PUCCH resources as target PUCCH resources, and the terminal device may respectively transmit SRs on the 3 PUCCH resources, and when the terminal device receives SRs on the 3 PUCCH resources, may allocate PUSCH resources for transmitting uplink data to the terminal device according to a sum of data amount intervals corresponding to the 3 PUCCH resources, respectively.

Mode two: the terminal device may sort the priorities of the N uplink logical channels, and use the data amount to be transmitted of the uplink logical channel with the highest priority as the basis for selecting the candidate PUCCH resource from each PUCCH resource group in at least one PUCCH resource group. That is, assuming that n=4, the identifiers are respectively 0 to 3, the identifier of the uplink logical channel with the highest priority is 2, the amount of data to be transmitted of the uplink logical channel is a, the at least one PUCCH resource group is 2 PUCCH resource groups, namely PUCCH resource group 1 and PUCCH resource group 2, respectively, and 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, respectively, according to the amount of data to be transmitted a. Since the PUCCH resources included in the PUCCH resource group 1 may be the same as or different from the PUCCH resources included in the PUCCH resource group 2, if they are the same, the candidate PUCCH resources respectively selected from the two PUCCH resource groups may be the same; if different, 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 a suitable PUSCH for an 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, and specifically, the data to be transmitted of which uplink logical channel is transmitted may be determined by the terminal device.

Mode three: the terminal device may add the data amounts to be transmitted of the N uplink logical channels, and use the sum of the data amounts to be transmitted of the N uplink logical channels as a basis for selecting candidate PUCCH resources from each PUCCH resource group in at least one PUCCH resource group, respectively. That is, assuming that n=4, the sum of the amounts of data to be transmitted of the 4 uplink logical channels is B, the at least one PUCCH resource group is 2 PUCCH resource groups, namely PUCCH resource group 1 and PUCCH resource group 2, respectively, and 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, respectively, according to the amount of data to be transmitted B. Since the PUCCH resources included in the PUCCH resource group 1 may be the same as or different from the PUCCH resources included in the PUCCH resource group 2, if they are the same, the candidate PUCCH resources respectively selected from the two PUCCH resource groups may be the same; if different, 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 received the SR may enable the terminal device to transmit the data to be transmitted of all the current uplink logical channels, so that the time delay in the uplink scheduling process may be greatly reduced.

Optionally, in the embodiment of the present application, the network device may configure at least one uplink Bandwidth Part (BWP) for the terminal device, and then, for any uplink BWP, the network device may separately configure a plurality of PUCCH resources for transmitting SRs. That is, the network device may configure N PUCCH resources for the uplink BWP1, and configure M PUCCH resources for the uplink BWP2, where N may be equal to or different from M. Further, the network device may configure a number to the terminal device through broadcast or radio resource control (Radio Resource Control, RRC) dedicated signaling, and the terminal device may know how many PUCCH resources per uplink logical channel are on the BWP configured by the network device as long as the number is received. For each uplink logical channel to be configured with PUCCH resources for transmitting SRs, the network device may select, from N PUCCH resources on uplink BWP1, the number of PUCCH resources broadcast by the network device to be configured with the uplink logical channel; and selecting the quantity of PUCCH resources broadcasted by the network equipment from M PUCCH resources on the uplink BWP2 to be allocated to the uplink logic channel.

When the network device broadcasts the number of PUCCH resources to the terminal devices, the number of PUCCH resources configured by each uplink logical channel of different terminal devices is the same, but the number of PUCCH resources configured by different terminal devices on one uplink BWP is not necessarily the same. For example, the number of PUCCH resources broadcast by the network device is 2.UE1 has 2 uplink Logical Channels (LCs): LC11 and LC12, LC11 configures PUCCH resource 1 and PUCCH resource 2 on one uplink BWP, and LC12 configures PUCCH resource 1 and PUCCH resource 3 on the same uplink BWP, wherein the data amount intervals corresponding to PUCCH resource 2 and PUCCH resource 3 may be the same, but may be used for allocation to different LCs of the UE. UE2 has 2 LCs: LC21 and LC22, LC21 configures PUCCH 4 and PUCCH 5 on one uplink BWP, and LC22 configures 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 number of the PUCCH resources is the same, the network device may only need to configure one PUCCH resource for the uplink logical channel of one terminal, and the number of the PUCCH resources configured is the same for all uplink logical channels on the uplink BWP where the PUCCH resources are configured. If the number of PUCCH resources is different, the network device needs to configure the number of PUCCH resources for the uplink logical channel of one terminal.

Alternatively, for the same uplink logical channel configured with PUCCH resources of the terminal device, the number of PUCCH resources corresponding to different uplink BWP may be the same or different. That is, when the network device configures PUCCH resources for each uplink logical channel, the network device may be associated with an uplink BWP, and the network device may configure a number of PUCCH resources for one uplink logical channel, so that the terminal device may determine that the number of PUCCH resources corresponding to the uplink logical channel is the same on any BWP; the network device may also configure the number of PUCCH resources for different BWP for one uplink logical channel, respectively. The terminal device may determine the number of PUCCH resources corresponding to the uplink logical channel corresponding thereto on any one BWP, respectively.

The configuration of PUCCH resources may include the following parameters: time domain resource locations and resource indexes. Any two PUCCH resources in one PUCCH resource group corresponding to one uplink logical channel may be the same in time domain resource position and different in resource index; or the time domain resource positions are different, and the resource indexes are the same; or it may be that the time domain resource location is different from the resource index. Wherein the time domain resource locations may be characterized by a period and/or a time offset.

As apparent from the above description, the terminal device may receive configuration information transmitted by the network device, and in particular, may include at least one of configuration information of an uplink BWP, configuration information of an uplink logical channel, and configuration information of an 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, a plurality of PUCCH resources for transmitting SRs are configured. For another example, the configuration information of the uplink logical channel may refer to whether PUCCH resources for transmitting SRs are configured for each uplink logical channel of the terminal device. If the PUCCH resources configured for the uplink logical channel to transmit SR are selected, 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 an uplink logical channel in which PUCCH resources for transmitting SRs are configured for each terminal device, where N PUCCH resources for transmitting SRs configured on the same uplink BWP in the uplink logical channel may respectively correspond to N data volume sections.

Optionally, the terminal device may further acquire first information in advance, where the first information is used for a number of multiple PUCCH resources configured for the terminal device, and/or a correspondence between PUCCH resources and a data volume interval. And the terminal equipment can determine the target PUCCH resource from the plurality of PUCCH resources through the data quantity to be transmitted. Alternatively, the first information may be predefined information, information broadcasted by a system message, or information carried in RRC signaling.

The method of the embodiment of the application is particularly suitable for NTN, so that the terminal equipment can obtain the rough uplink data transmission requirement of the terminal equipment through the SR transmission, and the scheduling of the network equipment can be obtained as soon as possible to transmit the uplink data, thereby reducing the uplink service time delay.

Three specific embodiments provided herein will be described in detail below in conjunction with fig. 4-6.

Example 1: the number of 1 SR resources configured on one uplink BWP by the uplink logical channel may be determined through network broadcasting or a predefined manner. For all terminals in a cell, if SR resources are configured for uplink logical channels of the terminals, the number of SR resources on one uplink BWP of the uplink logical channels of different terminals is the same.

1. The UE receives the system message (including UE1 and UE 2), acquires the following information:

1. in the case where the network configures PUCCH resources for transmission of SRs for an uplink logical channel, the network assigns the number n_sr=3 of PUCCH resources for transmission of SRs configured on each uplink BWP to the uplink logical channel.

2. 2 uplink data amount thresholds ul_data_th_1 and ul_data_th_2, wherein ul_data_th_1< ul_data_th_2. With these 2 threshold configurations, the uplink data amount can be divided into 3 levels (levels) according to the data amount size:

uplink data amount level 1:0< uplink data amount < = ul_data_th_1

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

Uplink data volume level 3 uplink data volume > ul_data_th_2

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

2. for UE1 and UE2, respectively configuring 3 PUCCH resources for transmitting SR on the configured uplink BWP, and respectively indicating an uplink data amount level corresponding to each PUCCH resource.

3. For UE1 and UE2, 1 uplink logical channel is configured, and 3 PUCCH resources for transmitting SR are configured for the uplink logical channel, respectively. The 3 PUCCH resources configured for each uplink logical channel for transmitting SRs are 3 PUCCH resources configured for the UE on uplink BWP in (two).

3. For UE1, if at a certain moment UE1 has uplink data arrives, a Regular BSR is triggered, and UE1 has no uplink resource for transmitting the initial transmission, UE1 triggers an SR. The current data size of the UE1 is in the data size range corresponding to the uplink data size level1, so that the UE transmits the SR on the PUCCH resource corresponding to the uplink data size level1 nearest to the current time.

4. The network receives the SR sent by the UE1, and according to the PUCCH resource position for receiving the SR, the network can acquire that the data volume of the UE is the uplink data volume level1, and the network allocates proper PUSCH resources for the UE according to the data volume information.

5. If at a certain moment UE1 has uplink data arrived, regular BSR is triggered, and UE1 has no uplink resource for transmitting the initial transmission, UE1 triggers SR. The current data size of the UE1 is in the data size range corresponding to the uplink data size level3, so the UE transmits the SR on the PUCCH resource corresponding to the uplink data size level3 nearest to the current time.

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

7. For UE2, at a certain moment, when UE2 has uplink data arrived, a Regular BSR is triggered, and UE2 has no uplink resource for transmitting the initial transmission, UE2 triggers an SR. The method for UE2 to select PUCCH resources to send SR according to the current data amount is the same as UE1, for example, SR is triggered at a certain time, the current data amount of UE2 is at level3 or SR is triggered at a certain time, and the current data amount of UE2 is at level 2, which is not described herein.

A schematic of example 1 is shown in fig. 4.

Example 2: the number of SR resources configured on one uplink BWP by the uplink logical channel may be determined through network broadcasting or a predefined manner. For all terminals in a cell, if SR resources are configured for the uplink logical channels of the terminal, the number of SR resources on one uplink BWP for the uplink logical channels of different terminals may be different.

1. in the case where the network configures PUCCH resources for transmission of SRs for an uplink logical channel, the network assigns the uplink logical channel the number n_sr1=2 and n_sr2=3 of PUCCH resources for transmission of SRs configured on each uplink BWP.

2. 2 sets of uplink data amount threshold values:

the first set of threshold values corresponds to n_sr1=2, comprising 1 uplink data amount threshold ul_data_th_1_1. With the 1 threshold configuration, the uplink data size can be divided into 2 levels according to the data size: an upstream data amount level11 of 0< upstream 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, comprising 2 uplink data amount thresholds ul_data_th_1_2 and ul_data_th_2_2, wherein ul_data_th_1_2< ul_data_th_2_2. With these 2 threshold configurations, the uplink data size can be divided into 3 levels according to the data size: an upstream data amount level12 of 0< upstream data amount < = ul_data_th_1_2; uplink data amount level22 uplink data th 12 uplink data amount < = ul data th 2; uplink data amount level32 uplink data amount > ul_data_th_2_2.

The current data size of UE1 is in the data size range corresponding to the uplink data size level12, so UE1 transmits SR on PUCCH resource corresponding to the uplink data size level12 nearest to the current time.

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

5. At a certain moment, when UE1 has uplink data arrived, a Regular BSR is triggered, and UE1 has no uplink resource for transmitting the initial transmission, UE1 triggers an SR. The current data size of UE1 is in the data size range corresponding to the uplink data size level32, so the UE transmits SR on the PUCCH resource corresponding to the uplink data size level32 nearest to the current time.

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