Detailed Description

To make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which the embodiment of the present invention is applicable, and as shown in fig. 1, the network structure includes a terminal 11 and a network side device 12, where the terminal 11 may be a User Equipment (UE) or other terminal devices, for example: the present invention relates to a Mobile terminal, and more particularly to a Mobile terminal, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), a robot, a vehicle, and other terminal-side devices. The network side device 12 may be a base station, for example: macro station, LTE eNB, 5G NR NB, etc.; the network side device may also be a small station, such as a Low Power Node (LPN), pico, femto, or the network side device may be an Access Point (AP); the network side device may also be a Central Unit (CU), or may be a network node such as a Transmission Reception Point (TRP). It should be noted that, in the embodiment of the present invention, the specific type of the network-side device is not limited.

Referring to fig. 2, fig. 2 is a flowchart of an uplink transmission control method according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:

201. a terminal receives a first MAC layer command sent by network side equipment, wherein the first MAC layer command is used for forbidding a target logic channel to perform uplink transmission or reducing the transmission priority of the target logic channel or limiting the transmission rate of the target logic channel;

202. and the terminal executes uplink transmission control corresponding to the first MAC layer command aiming at the target logic channel.

The first MAC layer command may be a MAC layer control command, for example: and MAC CE.

The target logical channel may be one or more logical channels, and further, the target logical channel may be a specific logical channel.

The prohibiting the target logical channel from performing uplink transmission may be to stop the uplink transmission of the target logical channel, that is, the target logical channel does not perform uplink transmission any more. For example: when Data organization is performed, data of a target logical channel is not organized into a MAC Protocol Data Unit (PDU).

The reducing of the transmission priority of the target logical channel may be that the target logical channel performs uplink transmission with the lowest logical channel priority. Here, the lowest logical channel priority may be the lowest logical channel priority supported by the target logical channel or supported by the terminal. This effectively limits the transmission rate of the target logical channel. Of course, the step of lowering the transmission priority of the target logical channel may also be to lower the transmission priority of the target logical channel by one or more transmission priority levels from the current transmission priority.

The limiting of the transmission rate of the target logical channel may be to limit the transmission rate of the target logical channel to a certain absolute transmission rate, or to limit the transmission rate of the target logical channel to a certain proportion of the current transmission rate, for example: 25%,50% and 75%.

The terminal may execute uplink transmission control corresponding to the first MAC layer command for the target logical channel, where if the first MAC layer command is used to prohibit the target logical channel from performing uplink transmission, the target logical channel is prohibited from performing uplink transmission; the above-mentioned terminal may execute the uplink transmission control corresponding to the first MAC layer command for the target logical channel, where if the first MAC layer command is used to decrease the transmission priority of the target logical channel, the transmission priority of the target logical channel is decreased; the above-mentioned terminal may execute the uplink transmission control corresponding to the first MAC layer command for the target logical channel, where if the first MAC layer command is used to limit the transmission rate of the target logical channel, the transmission rate of the target logical channel is limited.

In addition, the first MAC layer command may be sent by the network side device according to the uplink data amount of the target logical channel, for example: the network side equipment counts the uplink Data Volume transmitted by the configured logic channel, and if the uplink Data Volume reaches or exceeds a Maximum Data Burst Volume (MDBV) value, the network side equipment indicates a target logic channel reaching an MDBV threshold to prohibit uplink transmission, reduce the transmission priority or limit the transmission rate when sending an MAC layer command.

In the embodiment of the invention, the uplink transmission of the target logical channel can be controlled through the method, so that the target logical channel is prevented from using too many resources, the resource waste is reduced, and the normal transmission of data of other logical channels can be ensured.

As an optional implementation manner, the target logical channel is an uplink logical channel which is configured by Radio Resource Control (RRC) signaling and allows uplink transmission control.

In this embodiment, the network side device may configure, in advance through RRC signaling, one or more uplink logical channels allowing uplink transmission control for the terminal, where the target logical channel is a part or all of the one or more uplink logical channels. For example: before sending the MAC CE, the network side device configures, by RRC signaling, which logical channel or channels can prohibit transmission, or which logical channel or channels can change the priority of the logical channel, and/or reduce the transmission rate.

As an optional implementation manner, the first MAC layer command is a first MAC CE, and the target logical channel is one or more logical channels.

In this embodiment, uplink transmission control in which one MAC CE indicates one logical channel can be implemented. Or one MAC CE may indicate uplink transmission control of one or more logical channels.

In addition, when there are multiple logical channels, uplink transmission control indicated by different logical channels may be the same or different, for example: multiple logical channels all indicate that uplink transmission is prohibited, or some logical channels indicate that transmission priority is lowered, and another logical channel indicates that transmission rate is limited, or uplink transmission is prohibited.

As an optional implementation, the method further comprises:

the terminal receives a second MAC layer command sent by the network side equipment, wherein the second MAC layer command is used for canceling the uplink transmission control of the first MAC layer command on the target logic channel;

and the terminal cancels the uplink transmission control of the target logic channel according to the second MAC layer command.

Wherein, the second MAC layer command may be a MAC CE.

The above-mentioned cancelling the uplink transmission control of the first MAC layer command on the target logical channel may be to resume the uplink transmission control executed in step 202.

For example: the first MAC layer command is used for forbidding the target logic channel to carry out uplink transmission, so that the target logic channel can be recovered to carry out uplink transmission through the second MAC layer command; another example is: the first MAC layer command is to lower the transmission priority of the target logical channel, so that the transmission priority of the target logical channel can be recovered by a second MAC layer command; another example is: the first MAC layer command limits the transmission rate of the target logical channel so that the transmission rate of the target logical channel can be recovered by the second MAC layer command.

In this embodiment, the uplink transmission control of the target logical channel can be timely recovered by the second MAC layer command, so as to improve the transmission performance of the terminal.

In addition, the second MAC layer command and the first MAC layer command may be MAC CEs in a MAC CE format, that is, the MAC CEs in the format may instruct the uplink transmission control operation on the uplink transmission of the target logical channel, or may be used to instruct the uplink transmission control on the target logical channel to be recovered.

the first MAC CE corresponds to a first MAC subheader, and a first LCID included in the first MAC subheader is used for indicating that the first MAC CE is an MAC CE for adjusting the transmission rate;

the second MAC CE corresponds to a second MAC subheader, and a second LCID included in the second MAC subheader is used for indicating that the second MAC CE is a recovered transmission rate MAC CE;

wherein the first LCID and the second LCID have different values.

The MAC CE for adjusting the transmission rate may be understood as the MAC CE for performing uplink transmission control, or the MAC CE for turning on uplink transmission control. The above-mentioned MAC CE for recovering the transmission rate may be understood as a MAC CE for canceling the uplink transmission control, or a MAC CE for turning off the uplink transmission control.

For example: one MAC CE indicates to perform uplink transmission control operation on the uplink transmission of the target logical channel, corresponding to the MAC sub-header with LCID1, and the other MAC CE indicates to recover the uplink transmission control of the target logical channel, corresponding to the MAC sub-header with LCID 2.

The first MAC CE and the second MAC CE may be MAC CEs having the same MAC CE format, but the first MAC CE and the second MAC CE are not limited thereto.

Due to the adoption of the MAC CEs in the same MAC CE format, the addition of extra MAC layer commands can be avoided, so that the complexity is reduced.

The MAC CE for uplink transmission control may be uplink transmission control for validating a logical channel, or uplink transmission control for canceling a logical channel, or of course, uplink transmission control for validating a part of logical channels, and uplink transmission control for canceling another logical channel. In addition, the LCID may be a LCID specified in advance, such as a protocol agreement or configured by the network side to the terminal.

Since the LCID is used to indicate that the MAC CE is a MAC CE for uplink transmission control, the MAC CE format does not need to be modified to add a new format of MAC CE when uplink transmission control is performed on a logical channel, thereby reducing complexity.

Optionally, the MAC CE includes enable indications of a plurality of logical channels, where each enable indication is used to enable uplink transmission control of a corresponding logical channel or cancel uplink transmission control of a corresponding logical channel.

In this embodiment, an enable indication may be configured for each logical channel, so that uplink transmission control may be performed on some logical channels through one command, and uplink transmission control may be cancelled on another logical channel, thereby avoiding transmitting too many physical layer commands for uplink transmission control of the logical channels, and further saving transmission resources. For example: each logical channel is independently indicated, a bitmap (bitmap) mode is adopted, and the corresponding position of the logical channel in the bitmap is 0 or 1, namely, whether cancellation or validation is indicated.

Optionally, the MAC CE includes an enable indication, where the enable indication is used to enable uplink transmission control of all logical channels configured to allow uplink transmission control, or is used to cancel uplink transmission control of all logical channels configured to allow uplink transmission control.

In this embodiment, the enabling indication may be implemented as all logical channels, for example: the 1bit indicates the uplink transmission control operation of all logical channels. Further, in this embodiment, uplink transmission control of the uplink logical channel through the one enable indication may be implemented, instead of increasing the related indication information of the uplink logical channel, because the uplink logical channel allowed to perform uplink transmission control may be configured in advance through RRC signaling. Of course, when the MAC CE includes a logical channel indication, the enable indication may only act on the logical channel corresponding to the MAC CE.

As an optional implementation manner, the first MAC layer command includes one or more of the following:

wherein the logical channel indication indicates the target logical channel;

The logical channel indication may indicate the target logical channel through a Data Radio Bearer (DRB) number, an LCID, a number of a logical channel, or a bitmap.

For example: the network side equipment pre-configures which logic channels can carry out the uplink transmission control operation through RRC signaling, and numbers the logic channels and indicates corresponding numbers in a PDCCH; or the network side device does not display the number, and implicitly numbers according to the LCID or DRB ID size of the logical channel configured by the RRC and capable of performing the uplink transmission control operation or the sequence of configuring the logical channels, and indicates the corresponding number in the PDCCH, for example, if at most 8 logical channels can be configured to allow special operation, it indicates that the logical channel number field occupies 3 bits.

Another example is: the network side device pre-configures which logical channels can perform the uplink transmission control operation through RRC signaling, and numbers the logical channels, or the network side device does not display numbers, and implicitly numbers according to the size of LCID or DRB ID of the logical channels which are configured by the RRC and can perform the uplink transmission control operation or the sequence of configuring the logical channels, each bit of a bitmap corresponds to one configured logical channel, bit position 1 indicates that the logical channels are subjected to transmission prohibition or priority reduction operation, for example, if 3 logical channels are configured to allow special operation, the bitmap of the logical channels is indicated to be 3 bits.

The effective time may be an absolute time, such as in units of ms/subframe/timeslot; or for quantization indication, e.g. using Nbit with granularity of M slots, the maximum indicated duration is (2 ^ n-1) × M slots.

The indication of the reduced transmission rate may be a reduction in the PBR ratio, e.g., by 2 bits, with 0,1,2,3 representing a reduction in the PBR of 25%,50%, and 75%, respectively, of the original configuration value; or, the quantized absolute value, i.e. a specific value, e.g. 01, 10, etc., is indicated, by which the transmission rate limitation for the target logical channel is achieved.

Referring to fig. 3, fig. 3 is a flowchart of another uplink transmission control method according to an embodiment of the present invention, and as shown in fig. 3, the method includes the following steps:

301. the method comprises the steps that network side equipment sends a first MAC layer command to a terminal, wherein the first MAC layer command is used for forbidding a target logic channel to carry out uplink transmission or reducing the transmission priority of the target logic channel or limiting the transmission rate of the target logic channel.

Optionally, the target logical channel is an uplink logical channel that is configured by the radio resource control RRC signaling and allows uplink transmission control.

Optionally, the method further includes:

the first MAC CE corresponds to a first MAC subhead, and a first Logic Channel Identifier (LCID) included by the first MAC subhead is used for indicating the first MAC CE as an MAC CE for adjusting the transmission rate;

wherein the first LCID and the second LCID have different values.

Optionally, the first MAC layer command includes one or more of the following:

Optionally, the reducing the transmission priority of the target logical channel means: and the target logical channel carries out uplink transmission with the lowest logical channel priority.

It should be noted that, this embodiment is used as an implementation of the network side device corresponding to the embodiment shown in fig. 2, and specific implementation thereof may refer to the relevant description of the embodiment shown in fig. 2, so that, in order to avoid repeated description, the embodiment is not described again, and the same beneficial effects may also be achieved.

The following illustrates an uplink transmission control method provided by the embodiment of the present invention, with a network side device as a base station, a target logical channel as a specific logical channel, and an MAC layer command as an MAC CE:

example 1:

in this embodiment, the MAC CE has only a MAC subheader, i.e., the MAC CE length is fixed to 0.

The MAC CE is indicated with a specific LCID for adjusting the transmission rate or stopping the transmission rate adjustment. The transmission rate adjustment may refer to stopping uplink transmission of the logical channel, or reducing the priority of the logical channel (specifically, which manner may be specified by a protocol or configured by an RRC); the stopping of the transmission rate adjustment may be to recover the transmission rate, such as recovering a Logical Channel Priority (LCP) configuration, where the recovering of the LCP configuration refers to recovering an LCP parameter configured for the Logical Channel by using RRC.

For example: as shown in fig. 4, where 4-1 is the transmission rate adjusted MAC CE and 4-2 is the MAC CE configured to stop transmission rate adjustment.

In this embodiment, the base station side includes the following steps:

step 1: the base station configuring one or more logical channels with RRC signaling may adjust the transmission rate through the MAC CE.

Step 2: the base station counts the uplink data volume transmitted by the configured logical channel, and if the uplink data volume reaches or exceeds the MDBV value, the base station sends the transmission rate adjustment MAC CE shown in the figure 4-1 to inform the terminal of adjusting the transmission rate.

Step 3 (optional): if the protocol supports the MAC CE of fig. 4-2 for stopping the transmission rate adjustment configuration, the base station transmits the transmission rate adjustment configuration MAC CE of fig. 4-2 for recovering the transmission rate of the terminal when the transmission rate adjustment configuration of the terminal needs to be recovered.

In this embodiment, the terminal side includes the following steps:

step 1: the terminal receives RRC configuration of a base station side and determines which logical channel or logical channels can adjust the transmission rate;

and 2, step: the terminal receives the transmission rate adjustment MAC CE of the base station, if the transmission rate adjustment MAC CE is used for indicating to stop the uplink transmission of the logical channel, the terminal does not organize the data of the corresponding logical channel configured by the base station into the MAC PDU when the data organization is carried out; or, if the transmission rate MAC CE is adjusted to indicate that the priority of the logical channel is lowered, the terminal lowers the priority of the corresponding logical channel configured by the base station to the minimum when performing data organization.

Further, if the protocol does not support the MAC CE of fig. 4-2 for the stop transmission rate adjustment configuration, the transmission rate adjustment may be terminated in one of the following ways:

the base station side sends RRC signaling to reconfigure the LCP of the logical channel, and then organizes and transmits data according to the newly configured LCP;

the protocol stipulates or configures a maximum timer length through RRC, the terminal starts the timer after receiving the MAC CE for adjusting the transmission rate, and the LCP configuration of the logic channel is recovered after the timer reaches the configured maximum length.

Step 3 (optional): if the protocol supports the MAC CE configured to stop transmission rate adjustment shown in fig. 4-2, after receiving the MAC CE configured to stop transmission rate adjustment sent by the base station, the terminal resumes using the RRC configured LCP parameters, that is, resumes transmitting the uplink data of the logical channel, or resumes the priority and the transmission rate of the logical channel.

Example 2:

in this embodiment, the MAC CE carries a logical channel indication (for one logical channel).

The length of the MAC CE is fixed to 1byte, and the corresponding MAC sub-header is a sub-header indicating the fixed-length MAC CE, namely, the MAC sub-header is not provided with a length indication field L. The MAC CE includes a logical channel indication field and an adjustment/recovery rate adjustment indication field On/Off (optional) (specifically, see the enabling indication in the foregoing embodiment), where the logical channel indication field may be an LCID of a logical channel requiring rate adjustment, as shown in fig. 5-1, or a data bearer number DRB ID corresponding to the logical channel, as shown in fig. 5-2.

Among them, the roles of the MAC CE of fig. 5-1 and 5-2 are the same, and one of them is practically used. Adjusting the transmission rate refers to stopping uplink transmission of the logical channel or reducing the priority of the logical channel (specifically, which manner is specified by a protocol or configured by RRC); restoring the LCP configuration refers to restoring the LCP parameters configured for the logical channel using RRC.

In this embodiment, the base station side includes the following steps:

Step 2: the base station counts the uplink data amount transmitted by the configured logical channels, if the uplink transmission of a certain logical channel reaches or exceeds the MDBV value, the base station sends the MAC CE for adjusting the transmission rate of fig. 5-1 or fig. 5-2, the logical channel domain in the MAC CE indicates the logical channel of which the transmission rate needs to be adjusted, if there is an On/Off domain, the On/Off domain is set to be On (for example, corresponding to 1).

Step 3 (optional): if there is an On/Off field, the base station sends the adjusted transmission rate MAC CE of FIG. 5-1 or FIG. 5-2 when the LCP configuration of the terminal needs to be restored, and the On/Off field is set to Off (e.g., corresponding to 0).

In this embodiment, the terminal side includes the following steps:

step 1: the terminal receives the RRC configuration of the base station side and determines which logical channel or logical channels can adjust the transmission rate;

step 2: the terminal receives the transmission rate adjustment MAC CE of the base station, determines the logical channel of which the rate needs to be adjusted, and if the transmission rate adjustment MAC CE is used for indicating to stop the uplink transmission of the logical channel, the terminal does not organize the data of the logical channel into the MAC PDU when organizing the data; or, if the transmission rate MAC CE is adjusted to instruct to lower the priority of the logical channel, the terminal lowers the priority of the logical channel to the minimum when performing data organization.

Further, if the On/Off domain is not supported, i.e., the MAC CE has only rate adjustment function without recovery function, the transmission rate adjustment can be terminated in one of the following ways:

the base station side sends RRC signaling, reconfigures LCP of the logical channel, and then performs data organization and transmission according to the newly configured LCP;

the protocol prescribes or configures a maximum timer length through RRC, the terminal starts the timer after receiving the MAC CE for adjusting the transmission rate, and the LCP configuration of the logical channel is recovered after the timer reaches the configured maximum length.

Step 3 (optional): if the adjustment rate MAC CE has an On/Off domain, after receiving the adjustment rate MAC CE with the On/Off domain set as Off sent by the base station, the terminal resumes using the LCP parameters configured by the RRC for the logical channel indicated in the MAC CE, i.e. resumes transmitting the uplink data of the logical channel, or resumes the priority and transmission rate of the logical channel.

Example 3:

in this embodiment, the MAC CE carries a logical channel indication (for multiple logical channels).

The MAC CE is variable length or fixed length, the variable length MAC CE corresponds to the MAC subheader of the length indication field L, and the fixed length MAC CE corresponds to the MAC subheader of the non-length indication field L. One or more logical channel indication fields and an adjustment/recovery rate adjustment indication field On/Off (optional) are included in the MAC CE.
