Embodiment 1

[0191] This embodiment uses the token bucket suspension mechanism as an example to illustrate:

[0192] Network side:

[0193] Step 1: The network side device configures a token bucket suspension indication for the logical channel (logical channel 1) designated by the terminal. The indication may be configured for the DRB, or configured for the PDCP layer corresponding to the DRB, or configured for the logical channel corresponding to the DRB. The token bucket suspension indication may be RRC signaling or MAC layer signaling or physical layer signaling.

[0194] Step 2: The network side device schedules uplink resources for the terminal, and the uplink resources may also be pre-configured.

[0195] Step 3: The network side device receives the terminal's transmission on the uplink resource. If the uplink resource is within the transmission time window of logical channel 1, it may contain the data of logical channel 1; otherwise, it does not contain the data of logical channel...

Embodiment 2

[0203] This embodiment is also an example of the token bucket suspension mechanism

[0204] Network side:

[0205] Step 1: The network side device configures a token bucket suspension indication for the logical channel (logical channel 1) designated by the terminal. The indication may be configured for the DRB, or configured for the PDCP layer corresponding to the DRB, or configured for the logical channel corresponding to the DRB. The token bucket suspension indication may be RRC signaling or MAC layer signaling or physical layer signaling.

[0206] Step 2: The network side device schedules uplink resources for the terminal, and the uplink resources may also be pre-configured.

[0207] Step 3: The network side device receives the terminal's transmission on the uplink resource, and the transmission on the uplink resource does not include the data of logical channel 1.

[0208] Step 4: The network side device sends a token bucket start instruction for logical channel 1.

Embodiment 3

[0218] This embodiment continues to use the token bucket suspension mechanism as an example:

[0219] Network side:

[0220] Step 1: The network side device configures a token bucket suspension indication for the logical channel (logical channel 1) designated by the terminal. The indication may be configured for the DRB, or configured for the PDCP layer corresponding to the DRB, or configured for the logical channel corresponding to the DRB. The token bucket suspension indication may be RRC signaling or MAC layer signaling or physical layer signaling.

[0221] Step 2: The network side device schedules uplink resources for the terminal, and the uplink resources may also be pre-configured.

[0222] Step 3: The network side device receives the terminal's transmission on the uplink resource. If the uplink resource is within the transmission time window of logical channel 1, it may contain the data of logical channel 1; otherwise, it does not contain the data of logical channel 1...

Abstract

The invention provides a data transmission method, a parameter configuration method, a terminal and network side equipment. The method comprises the following steps: the terminal caches data of a logic channel corresponding to a first service bearer; and the terminal limits to transmit the data in a transmission time window according to the logical channel priority parameter of the logical channel, and the transmission time window is a data transmission time window required according to the service characteristics of the first service bearer. The invention can improve the service transmission performance.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a data transmission method, a parameter configuration method, a terminal and a network side device. Background technique [0002] With the development of communication technology, some communication systems (such as: 5G communication system) support more and more services, including some services that require transmission within a specified time. The service requirements for internal transmission are called on-time transmission (on time transmission) services. However, at present, the terminal directly transmits data on the transmission resource after sending a scheduling request to obtain the transmission resource. However, the allocated transmission resource may not be within the transmission time required by the service, resulting in relatively poor service transmission performance.
