Description

Communication method and terminal deviceTechnical Field

The embodiment of the application relates to the technical field of communication, in particular to a communication method and terminal equipment.

Background

In a wireless communication system, there may be resource conflicts among multiple grants (grants) for a terminal device, in which case the terminal device performs transmissions for one of the grants.

Media Access Control (MAC) Protocol Data Unit (PDU) transmitted on the grant may encapsulate a Report of a MAC layer, for example, a Buffer State Report (BSR), however, in the above-mentioned scenario of resource conflict, when the BSR is encapsulated into one of the authorized MAC PDUs, the BSR will be cancelled and will not be encapsulated into another authorized MAC PDU, if the other authorized MAC PDU is transmitted on the conflicting resource, because the MAC Control Element (CE) of the BSR is not encapsulated in the other authorized MAC PDU, the BSR is not reported to the network side in time, thereby affecting the communication performance between the terminal device and the network.

As used herein, "terminal equipment" includes, but is not limited to, connections via wireline, such as Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), Digital cable, direct cable connection; and/or another data connection/network; and/or via a Wireless interface, e.g., to a cellular Network, a Wireless Local Area Network (WLAN), a digital television Network such as a DVB-H Network, a satellite Network, an AM-FM broadcast transmitter; and/or means of another terminal device arranged to receive/transmit communication signals; and/or Internet of Things (IoT) devices. A terminal device arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal", or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; personal Communications Systems (PCS) terminals that may combine cellular radiotelephones with data processing, facsimile, and data Communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver.

Optionally, a Device to Device (D2D) communication may be performed between theterminal devices 120.

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

Fig. 1 exemplarily shows one network device and two terminal devices, and optionally, thecommunication system 100 may include a plurality of network devices and may include other numbers of terminal devices within the coverage of each network device, which is not limited in this embodiment of the present application.

Optionally, thecommunication system 100 may further include other network entities such as a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

It should be understood that a device having a communication function in a network/system in the embodiments of the present application may be referred to as a communication device. Taking thecommunication system 100 shown in fig. 1 as an example, the communication device may include anetwork device 110 and aterminal device 120 having a communication function, and thenetwork device 110 and theterminal device 120 may be the specific devices described above and are not described herein again; the communication device may also include other devices in thecommunication system 100, such as other network entities, for example, a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

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

During the communication between the terminal device and the network device, the network device may assign an authorization to the terminal device, and the assigned authorization may include a configuration authorization (Configured Grant) and/or a dynamic authorization. The configuration authorization may be configured by the network device to the terminal device semi-statically, and the dynamic authorization may be dynamically scheduled by the network device to the terminal device, for example, may be scheduled to the terminal device through Downlink Control Information (DCI). Each grant may correspond to a resource for transmitting a MAC PDU. In the embodiments of the present application, authorization may also be understood as a resource.

On the terminal device side, there may be a case where multiple authorized resources conflict. The resource conflict of multiple grants may mean that resources occupied by multiple grants are completely the same, or that the resources occupied by multiple grants partially overlap.

In the case of resource conflicts with multiple grants of a terminal device, the terminal device will perform a transmission for one of the grants.

For example, as shown in fig. 2, DCI1 and DCI2 allocategrant 1 and grant 2 to the terminal device, respectively, wheregrant 1 and grant 2 have overlapping resources, where the time of the group packet of MAC PDU1 forgrant 1 is earlier than the time of the group packet of MAC PDU2 for grant 2 (at this time, the start position occupied bygrant 1 in the time domain may be earlier than the time domain position occupied by grant 2 in the time domain, and/or the time domain length ofgrant 1 may be longer than the time domain length of grant 2), if the priority of the traffic of grant 2 is higher than that of the traffic ofgrant 1, the MAC PDU2 will be transmitted on grant 2, and the MAC PDU1 will be dropped or wait for the subsequent grant to be transmitted.

On the terminal device side, when new uplink data arrives (i.e., new uplink data is generated), in the MAC layer, generating a BSR may be triggered, where the BSR may be used to generate a MAC CE, and the MAC CE may be encapsulated in a MAC PDU.

For example, as shown in fig. 2, before the MAC PDU1 is packed, BSR1 is triggered by the arrival of new uplink data, the MAC CE of BSR1 may be encapsulated in MAC PDU1, and when the MAC PDU1 is packed, the BSR1 may be cancelled.

And as shown in fig. 2, the MAC PDU2 can be encapsulated for grant 2, at which point the terminal device can transmit the MAC PDU2 on grant 2 and discard the MAC PDU1 or buffer the MAC PDU1 for subsequent transmission, since the priority of the traffic for grant 2 is higher compared to the priority of the traffic forgrant 1.

This implementation may ensure that the service with high priority can be transmitted in time, but if the MAC CE of the BSR is encapsulated into the MAC PDU of the service with low priority, such as the BSR is encapsulated into the MAC PDU1 described above, but not into the MAC PDU2, the BSR cannot be reported to the network side.

Based on this, the embodiments of the present application provide the following scheme, which can avoid the problem that a triggered report, for example, a BSR, cannot be reported to the network side, thereby improving communication performance.

Fig. 3 is a schematic flow chart diagram of acommunication method 200 according to an embodiment of the present application. Themethod 200 includes at least some of the following.

In 210, when transmitting a first MAC PDU on a first uplink channel resource, a terminal device cancels a first report, where the first report is used to generate a first MAC CE included in the first MAC PDU.

Specifically, the terminal device may generate a first MAC CE based on the first report, encapsulate the first MAC CE into a first MAC PDU, and transmit the first MAC PDU on the first uplink channel resource, and when transmitting the first MAC PDU on the first uplink channel resource, the terminal device may cancel the first report.

The timing of canceling the first report may be performed from a starting point of transmitting the first MAC PDU, or may be performed at an intermediate time point of transmitting the first MAC PDU, or may be performed at a time point of ending transmission of the first MAC PDU.

Optionally, the Uplink Channel resources (e.g., the first Uplink Channel resource and the second Uplink Channel resource) in the embodiment of the present application may be a Physical Uplink Shared Channel (PUSCH).

Alternatively, the report mentioned in the embodiment of the present application (which may be the first report mentioned above, the second report mentioned below, and the third report) may be a MAC layer triggered report. The Report in the embodiment of the present application may specifically be a BSR, a Power Headroom Report (PHR), or a configuration authorization confirmation.

Optionally, the BSR in the embodiment of the present application may be classified as a retransmission BSR, a periodic BSR, a padding BSR, (padding BSR), a long BSR, (long BSR), a short BSR, (short BSR), or a truncated BSR (truncated BSR). The Truncated BSR may be further divided into a short Truncated BSR (short Truncated BSR) or a long Truncated BSR (long Truncated BSR).

Optionally, the PHR in the embodiment of the present application may be a periodic PHR.

Optionally, the configuration authorization confirmation in this embodiment may be a report confirming that the network device confirms the configuration authorization, the activation authorization, or the deactivation authorization to the terminal device.

Optionally, the report in the embodiment of the present application may be a report triggered periodically or a report triggered by a special event.

Taking the report as a BSR as an example, the BSR may be a report triggered periodically, or may also be a report triggered by the arrival of uplink data.

The MAC PDU in the embodiment of the present application may include a plurality of MAC sub-PDUs, where the MAC sub-PDUs may include a Service Data Unit (SDU) and a sub-header thereof, or may include a MAC CE and a sub-header thereof, where the MAC CE may be a fixed-size MAC CE or a variable-length MAC CE, for example, as shown in fig. 4.

And as shown in fig. 5, the subheader of the MAC CE may include a Logical Channel Identity (LCID), where the LCID is used to distinguish what type of report the MAC CE corresponds to, for example, a long BSR, a short BSR, a PHR, or the like. Where R in fig. 5 represents a reserved bit, L represents a byte length occupied by the corresponding MAC CE, F represents a size of a length field (of the MAC CE),

as shown in fig. 6 and 7, the MAC CE may include a Logical Channel Group (LCG) identifier (Identity, ID) and a buffer size of the logical Channel Group, where fig. 6 shows a format of the MAC CE of the short BSR or the truncated BSR, that is, an identifier of a logical Channel Group and a buffer size thereof; fig. 7 shows the format of the MAC CE of the long BSR or the long truncated BSR, i.e. the identity of the group of multiple logical channels and their buffer size.

Optionally, the report in this embodiment may be a report triggered based on a Logical Channel (LC) or a logical Channel group, and may also be referred to as a report of a per logical Channel or a logical Channel group.

Optionally, in this embodiment of the present application, a logical channel or a logical channel group may correspond to a service, for example, one service may correspond to at least one logical channel or a logical channel group, and different services may correspond to logical channels or logical channel groups that are completely different.

In the embodiment of the present application, all logical channels in one logical channel group may correspond to the same service, or may correspond to different services.

The categories of the logical channels in the embodiment of the present application may be divided according to the corresponding services, for example, the logical channels corresponding to the same service (where the logical channels may be a logical channel group) may be the same type of logical channels, or the logical channel group including the same service may be the same type of logical channel group, or the categories of the logical channels may also be divided based on the logical channel group to which the logical channels belong, for example, the logical channels belonging to the same logical channel group may be the same type of logical channels.

Wherein, the report triggered based on the logical channel or the logical channel group can be understood as: the reporting is based on service triggered reporting, and the logical channel or logical channel group mentioned here is the logical channel or logical channel group corresponding to the service. Service-based triggering may also be referred to as reporting is per-service.

Optionally, the information carried in the report is information based on a service, where the service is a service of a certain logical channel or logical channel group, and the logical channel or logical channel to which the report belongs is the certain logical channel or logical channel group.

Optionally, in this embodiment of the present application, the reported MAC CE may carry an identifier (LCID) of the logical Channel on which the MAC CE is based.

For example, as shown in fig. 8 and 9, the MAC CE may carry an identifier of a logical channel to which the report belongs. Fig. 8 illustrates information of buffer sizes of one logical channel encapsulated in the MAC CE. Fig. 9 illustrates information of buffer sizes of a plurality of logical channels encapsulated in the MAC CE. The plurality of logical channels in fig. 9 may be a type of logical channel, and may correspond to the same service, for example.

Fig. 9 shows information of buffer sizes of 8 logical channels, and if the number of logical channels of a service is less than 8 or there are less than 8 logical channels with buffered data, the MAC CE may carry the identifier of the logical channel less than 8 and its buffer size. At this time, the size of the MAC CE may be variable.

For example, as shown in fig. 10, the identifiers of 5 logical channels and their buffer sizes may be carried, and the other bit positions may be reserved bits R.

Or, in this embodiment of the present application, when the report is based on the service trigger, and a service may correspond to at least one logical channel group, the identification information of the at least one logical channel group and the buffer size thereof may be carried in the MAC CE.

For example, as shown in fig. 11, the logical channel groups corresponding to the services may be 4, the identifiers of the 4 logical channel groups and the buffer sizes thereof may be carried in the MAC CE, and the other bits may be reserved bits.

Optionally, in this embodiment of the present application, the first report is a report of a first logical channel, and the first report is triggered when a condition for triggering the report of the first logical channel is satisfied.

Wherein the condition for triggering reporting of the first logical channel comprises at least one of:

1) the first logical channel or the logical channel group to which the first logical channel belongs has data to be transmitted.

2) The first logical channel has data to be transmitted, and the logical channels except the first logical channel in the logical channel group to which the first logical channel belongs have no data to be transmitted.

3) The first logic channel has data to be transmitted, and a fourth logic channel in a logic channel group to which the first logic channel belongs has data to be transmitted, and the priority of the fourth logic channel is lower than that of the first logic channel.

4) The first uplink channel resource is allocated for transmitting data of the first logical channel or a logical channel group to which the first logical channel belongs.

5) The number of bits remaining after data transmission in the first uplink resource channel resource is greater than or equal to a first value, where the first value is the number of bits occupied by the first MAC CE and the subheader of the first MAC CE.

6) The retransmission report timer of the first logical channel or the logical channel group to which the first logical channel belongs is expired.

7) The periodic report timer of the first logical channel or the logical channel group to which the first logical channel belongs is expired.

Optionally, in this embodiment of the present application, the logical channel of the first report and the logical channel to which the data of the first grant bearer belongs are the same logical channel or the same type of logical channel, or the first grant can satisfy a logical channel priority mapping limitation configured for the logical channel of the first report, where the first grant is a grant corresponding to the first MAC PDU.

Specifically, when a certain type of logical channel or a grant of a certain logical channel encapsulates a MAC PDU, a report of the logical channel of the certain type of logical channel may be encapsulated into the MAC PDU.

The logical channel priority mapping restriction of a logical channel or a logical channel group may indicate a requirement or restriction on an authorization when information in the logical channel or the logical channel group is transmitted by using the authorization, and data or information in the logical channel or the logical channel group may be transmitted on the authorization if the authorization meets the requirement or restriction.

Therefore, the reporting of the first report to the network side through the MAC PDU which has the same logical channel or the same kind of logical channel as the first report in the embodiment of the present application can be understood as: and reporting the first report to the network side through the MAC PDU with the same service as the first report.

The first grant mentioned in the embodiment of the present application can satisfy the logical channel priority mapping restriction configured for the logical channel or the logical channel group associated with the first report, that is, it can be understood as: the logical channel priority mapping restriction of the first reported logical channel or logical channel group matches the first grant (which may specifically be an attribute of the first grant).

Optionally, in this embodiment of the present application, when the first MAC PDU is transmitted on the first uplink channel resource or before the first MAC PDU is transmitted, the terminal device cancels a second report, where the second report is triggered between the grouping of the first MAC PDU and the transmission of the first MAC PDU on the first uplink channel resource.

Specifically, since the second report is triggered after the first MAC PDU group package and before the first MAC PDU is transmitted, compared with the first report, the second report may be some reports that are duplicated to the information content of the first report or reports that contain useless information, for example, the second report is a retransmission BSR, a periodic BSR, or a padding BSR, the second report may be cancelled, specifically, the second report may be cancelled when the first MAC PDU is transmitted on the first uplink channel resource, or, since the second report is a relatively useless report, the second report may be cancelled before the first MAC PDU is transmitted, of course, the second report may also be cancelled after the first MAC PDU is transmitted, which is not limited in the embodiment of the present application.

Wherein the second report is optionally a report satisfying the following condition: have the same kind of logical channel or the same logical channel as the first report. The first report and the second report have the same type of logical channel or the same logical channel may mean that the services to which the first report and the second report belong are the same, or may mean that the first report and the second report have the same type of logical channel or information in the same logical channel, or may mean that the first report and the second report have the same type of logical channel group or information in the same logical channel group.

Specifically, the first report and the second report have the same kind of logical channel or the same logical channel, and the second report usually contains some duplicated information with respect to the first report, and at this time, the first report may be cancelled.

Wherein, the first report and the second report have the same kind of logical channel or the same logical channel, it can be understood that the first report and the second report are reports of the same service respectively.

In the embodiment of the present application, the logical channel or the logical channel group that the first report has may be referred to as: the logical channel or logical channel group to which the first report belongs, the logical channel or logical channel group of the first report, or the logical channel or logical channel group with which the first report is associated.

Optionally, in this embodiment of the present application, the report is associated with a logical channel group, which may mean that the report includes information in the logical channel. And, reporting is associated with a logical channel group, which may refer to reporting information in logical channels that include all or part of the logical channel group.

Alternatively, in the embodiment of the present application, the report is associated with the logical channel group, and may refer to that the report includes information of a service corresponding to the logical channel. And, reporting is associated with a logical channel group, which may refer to reporting information including traffic corresponding to all or part of the logical channels in the logical channel group.

The service mentioned in the embodiment of the present application may be enhanced Mobile bandwidth (eMBB) service, massive Machine-Type Communications (mtc) service, ultra-Reliable Low latency Communications (urlclc) service, and Industrial Internet of Things (IIoT) service.

Optionally, in this embodiment of the present application, the terminal device may reserve a third report until a second MAC PDU is transmitted on a second uplink channel resource, where the second MAC PDU includes a second MAC CE generated based on the third report; the third report is triggered between packing the first MAC PDU with a packet and transmitting the first MAC PDU on the first uplink channel resource.

Specifically, a third report is triggered between the first MAC PDU grouping and the transmission of the first MAC PDU on the first uplink channel resource, and the third report may also be retained until the second MAC PDU encapsulating the MAC CE of the third report is transmitted on the second uplink channel resource.

Wherein the third report may not be cancelled when the third report is a report satisfying at least one of the following conditions:

triggered by the arrival of upstream data;

a second logical channel having a non-first logical channel, or a third logical channel that is not of the same class as the first logical channel, the first logical channel being a logical channel to which the first report belongs.

Specifically, if the third report is triggered by the arrival of uplink data, the information of the third report is relatively useful for the terminal device, and the terminal device can request the network device for authorization by reporting the BSR to the network device.

And if the first report and the third report have different logical channels or different classes of logical channels, the third report represents that the third report is a report triggered by other services, and the third report is not a repeat of the first report, so that the third report needs to be reported to the network side.

Optionally, in this embodiment of the present application, the first uplink channel resource is configured to transmit a MAC PDU of a first grant and a second grant; the first granted MAC PDU is the first MAC PDU; the second granted MAC PDU is a third MAC PDU, the third MAC PDU is packed before the first MAC PDU and is not transmitted on the first uplink channel resource, and the third MAC PDU includes the first MAC CE.

Specifically, as mentioned above, in the case that there is a resource conflict among multiple authorized resources, the terminal device may transmit one authorized first MAC PDU on the conflicted resource, even if a second authorized third MAC PDU exists before the first MAC PDU and encapsulates the first report, since the first report is not cancelled, the terminal device may generate a MAC CE based on the first report to encapsulate into the first MAC PDU, so that it may be realized that the first report may be reported to the network side through the first MAC PDU even if the previous third MAC PDU is not transmitted.

The grant mentioned in the embodiment of the present application may be a configured grant or a dynamic grant, where the configured grant may be configured semi-statically by the network device, for example, may be configured through RRC signaling, and the dynamic grant may be scheduled by the network device to the terminal device through DCI.

For example, to more clearly understand the present application, the first report is taken as a BSR as an example, and the embodiment of the present application is described below with reference to fig. 1.

As shown in fig. 2, DCI1 and DCI2 allocategrant 1 and grant 2 to a terminal device, respectively, and a resource ofgrant 1 and a resource of grant 2 may have overlapping resources, assuming that the priority of grant 2 is higher than the priority ofgrant 1.

When a certain condition is met, for example, when new uplink data arrives, BSR1 will be triggered, BSR MAC CE generated based on BSR1 will be encapsulated into MAC PDU1, and MAC PDU1 is a MAC PDU forgrant 1.

Assuming thatgrant 1 has a higher priority than grant 2, the terminal device may transmit MAC PDU1 containing BSR MAC CE ongrant 1 and may cancel the BSR when transmitting this MAC PDU1, wherein, since MAC PDU2 for grant 2 will not be transmitted, there may be no need to encapsulate the BSR MAC CE into MAC PDU2 or may not generate MAC PDU 2.

Assuming that grant 2 has a higher priority thangrant 1, since the BSR1 has not been cancelled, a MAC CE may be generated based on the BSR1 and encapsulated into a MAC PDU2, a MAC PDU2 including the MAC CE of BSR1 is transmitted on grant 2, and the BSR is cancelled when transmitting MAC PDU 2.

Assuming that a new BSR2 exists after the grouping ofMAC PDUs 1 and before the transmission of a MAC PDU (MAC PDU1 or MAC PDU2) ongrant 1, the new BSR may or may not be cancelled when transmitting data ongrant 1.

For example, if the BSR2 is a retransmitted BSR, a periodic BSR, or a padding BSR, the BSR2 may be cancelled.

For example, if the BSR2 is a BSR triggered by the arrival of new uplink data, the BSR2 is not cancelled, and when waiting for encapsulating the MAC PDU3 for the next grant, a MAC CE is generated based on the BSR2 and encapsulated in the MAC PDU 3.

It should be understood that, in the embodiment of the present application, when the BSR2 arrives due to new uplink data, if the BSR2 is triggered after the MAC PDU1 is packed and before the MAC PDU2 is packed, and the MAC PDU2 is transmitted on grant 2, the MAC CE of the BSR2 may be encapsulated into the MAC PDU2 together with the MAC CE of the BSR1, or at least one of the two may be encapsulated into the MAC PDU2, or the MAC CE of the BSR2 may be encapsulated into the MAC PDU 2.

If the remaining bits of the uplink data transmitted byresource 1 are not enough to encapsulate the MAC CE and its subheader of BSR1 and the MAC CE and its subheader of BSR2 at the same time, only the MAC CE and its subheader of BSR1, or only the MAC CE and its subheader of BSR2, specifically which BSR MAC CE and its subheader are encapsulated, may be determined according to the priority of the BSR, and the priority of the BSR may be determined based on the priority of the logical channel or logical channel group to which the BSR belongs. Alternatively, the MAC CE of the previous BSR may be encapsulated, i.e., the MAC CE encapsulating BSR1 is in MAC PDU 2. Alternatively, the MAC CE of the following BSR may be encapsulated, i.e., the MAC CE of the encapsulated BSR2 is in the MAC PDU 2. MAC CEs inBSRs 1 and 2 that are not encapsulated can be encapsulated into the next authorized MAC PDU 3.

The above description is given by taking an example of overlapping two authorized resources, but it should be understood that the embodiments of the present application are also applicable to a scenario where more than two authorized resources overlap.

The above describes a scheme of how to cancel the report when the granted resources overlap, and how to perform the cancellation of the report in the case where the granted resources do not overlap will be described below.

As shown in fig. 12, the network device allocatesgrant 1 and grant 2 to the terminal device through DCI1 and DCI2, respectively, andresource 1 ofgrant 1 and resource 2 of grant 2 are non-overlapping resources. Since there are no overlapping resources forgrant 1 and grant 2, the MAC PDU1 encapsulated forgrant 1 may be sent onresource 1 and the MAC PDU2 encapsulated for grant 2 may be sent on resource 2, respectively.

When a certain condition is met, for example, when new uplink data arrives, BSR1 will be triggered, the MAC CE generated based on BSR1 will be encapsulated into MAC PDU1, MAC PDU1 is transmitted onresource 1 ofgrant 1, and BSR1 is cancelled when MAC PDU1 is transmitted.

Assuming that there is no new BSR after the MAC PDU1 package and before the MAC PDU2 package, the MAC CE of the BSR may not be included in the MAC PDU 2.

Or even if there is a new BSR before the MAC PDU2 group package after the MAC PDU1 group package, if the new BSR is a periodic BSR, a retransmitted BSR or a padding BSR, the new BSR may not be encapsulated in the MAC PDU 2. Where these new BSRs may be cancelled when triggered, or may also be cancelled when MAC PDU1 is transmitted onresource 1.

If, as shown in fig. 13, the BSR2 is triggered after the MAC PDU1 is packed inpacket 1 and before the MAC PDU2 is packed, the BSR2 is triggered by the arrival of new uplink data, the MAC CE of the BSR2 may be encapsulated in the MAC PDU2, and the BSR2 is cancelled when the MAC PDU2 is transmitted on resource 2.

In the embodiment of the present application, it is mentioned that the report may be triggered based on a logical channel, that is, the report may be triggered based on a per logical channel or a per service, and the manner of canceling the reports may not be limited to canceling the above-mentioned cancellation when the MAC PDU of the MAC CE encapsulating the report is transmitted, for example, the cancellation may be cancelled when the MAC PDU is encapsulated, or may be cancelled after the MAC PDU is encapsulated and before the MAC PDU is transmitted.

In the embodiment of the present application, when the first MAC PDU is transmitted, the first report used for generating the first MAC CE included in the first MAC PDU is cancelled, instead of when the MAC PDU is generated, the first report is cancelled, so that a problem that the first report cannot be reported to the network side due to the fact that the first MAC PDU is not transmitted can be avoided.

Specifically, when the first report is the BSR, the transmission requirement of the terminal device may be reported to the network side in time, so that the network device side may schedule the terminal device in time, and particularly when the BSR is a BSR based on a specific service (e.g., URLLC service), the QoS of the service may be ensured.

It should be understood that themethod 200 described above is merely a specific implementation of the present application, and that embodiments of the present application may have other implementations.

For example, when the terminal device cancels the first report used for generating the first MAC CE included in the first MAC PDU when transmitting the first MAC PDU on the first uplink channel resource as mentioned above, in this embodiment of the present application, if the terminal device determines that no grant other than the grant of the first MAC PDU exists on the first uplink channel resource, the first report may be cancelled when determining that this fact is true, for example, when or before the terminal device encapsulates the first MAC PDU, the terminal device determines that no grant other than the grant of the first MAC PDU exists on the first uplink channel resource, the terminal device cancels the first report when encapsulating the first MAC PDU; for example, if the terminal device determines that no grant other than the grant of the first MAC PDU exists on the first uplink channel resource after encapsulating the first MAC PDU, the first report may be cancelled when it determines that no grant other than the grant of the first MAC PDU exists on the first uplink channel resource.

Or, in the embodiment of the present application, even if the first uplink channel is used for multiple grants including the grant of the first MAC PDU, if the terminal device determines that the priority of the grant of the first MAC PDU is highest, the terminal device may cancel the first report when determining that the priority of the grant of the first MAC PDU is highest; if the terminal device determines that the priority of the grant of the first MAC PDU is highest before performing encapsulation of the first MAC PDU, the first report may be cancelled when performing encapsulation of the first MAC PDU.
