Embodiment approach

[0099] As an optional implementation, the method also includes:

[0100] The terminal receives a second MAC layer command sent by the network side device, where the second MAC layer command is used to cancel the uplink transmission control of the target logical channel by the first MAC layer command;

[0101] The terminal cancels the uplink transmission control on the target logical channel according to the second MAC layer command.

[0102] Wherein, the above-mentioned second MAC layer command may be a MAC CE.

[0103] The foregoing cancellation of the uplink transmission control of the target logical channel by the first MAC layer command may be to restore the uplink transmission control performed in step 202 .

[0104] For example: the above-mentioned first MAC layer command is to prohibit the target logical channel from performing uplink transmission, so that the target logical channel can be restored to perform uplink transmission through the second MAC layer command; an...

Embodiment 1

[0157] In this embodiment, the MAC CE has only the MAC subheader, that is, the length of the MAC CE is fixed at 0.

[0158] A specific LCID is used to indicate that the MAC CE is used to adjust the transmission rate or stop the transmission rate adjustment. Wherein, the transmission rate adjustment may refer to stopping the uplink transmission of the logical channel, or lowering the priority of the logical channel (specifically which method may be specified by the protocol or RRC configuration); stopping the transmission rate adjustment may be to restore the transmission rate, such as Restoring a logical channel priority (Logical Channel Prioritization, LCP) configuration, where restoring the LCP configuration refers to restoring the LCP parameters configured for the logical channel by using the RRC.

[0159] For example, as shown in FIG. 4 , 4-1 is a MAC CE for transmission rate adjustment, and 4-2 is a MAC CE for stopping transmission rate adjustment configuration.

[0160]...

Embodiment 2

[0172] In this embodiment, a logical channel indication (for one logical channel) is included in the MAC CE.

[0173] The length of the MAC CE is fixed at 1 byte, and the corresponding MAC subheader is a subheader indicating a fixed-length MAC CE, that is, without the length indicating field L. The MAC CE includes a logical channel indication field and an adjustment / recovery rate adjustment indication field On / Off (optional) (for details, please refer to the enabling indication in the previous embodiment), where the logical channel indication field can be the logic that needs to adjust the rate LCID of the channel, such as Figure 5-1 shown, or the data bearer number DRB ID corresponding to the logical channel, such as Figure 5-2 .

[0174] in, Figure 5-1 and Figure 5-2 The functions of the MAC CE are the same, and one of them can be selected for actual use. Adjusting the transmission rate refers to stopping the uplink transmission of the logical channel, or reducing t...

Abstract

The invention provides an uplink transmission control method, a terminal and network side equipment. The method comprises the steps that the terminal receives a first MAC layer command sent by the network side equipment, 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; and the terminal executes uplink transmission control corresponding to the first MAC layer command for the target logic channel. The embodiment of the invention can reduce resource waste.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to an uplink transmission control method, terminal and network side equipment. Background technique [0002] In some communication systems, the design of logical channel priority only considers the traffic required by the burst data within the packet delay budget (PacketDelay Budget, PDB), so that the transmission rate of the logical channel may be much higher than the guaranteed transmission rate in the actual transmission process. Flow rate (Guaranteed Flow Bit Rate, GFBR), thus occupying resources of other logical channels, resulting in waste of resources. Contents of the invention [0003] Embodiments of the present invention provide an uplink transmission control method, a terminal and a network side device, so as to solve the problem of waste of resources. [0004] An embodiment of the present invention provides an uplink transmission control method, incl...
