Methods devices, and systems, for allocation of uplink resources for wireless data transmission

A data transmission method, comprising:

• allocating, by a network side device, a first identifier (ID) to a terminal device, wherein the terminal device is located in a first area in which the network side device provides a service, and the first ID is valid in the first area;
• obtaining, by the network side device, mobility information of the terminal device, the mobility information comprising a terminal device mobility attribute indicative of the terminal device being a fixed terminal device or a moveable terminal device;
• determining, by the network side device, a target grant free resource based on the mobility information, wherein the target grant free resource is determined to be a dedicated grant free resource when the terminal device mobility attribute is indicative of the terminal device being the fixed terminal device or determined to be a universal grant free resource when the terminal device mobility attribute is indicative of the terminal device being the moveable terminal device, and wherein data information received by the network side device using the universal grant free resource comprises data and an ID of the terminal device sending the data, and data information received by the terminal device using the dedicated grant free resource comprises data, wherein the determining, by the network side device, the target grant free resource based on the mobility information comprises:
• when a location of the terminal device is fixed or a location change of the terminal device is within a specified range, determining, by the network side device, that the target grant free resource is the dedicated grant free resource, and when the target grant free resource determined by the network side device is the dedicated grant free resource, the method further comprises:
• determining, by the network side device, a valid range of the dedicated grant free resource and sending, by the network side device, the valid range to the terminal device, and
• when a location change of the terminal device exceeds the specified range, determining, by the network side device, that the target grant free resource is the universal target grant free resource;
• and
• indicating, by the network side device, the target grant free resource to the terminal device.

A terminal device, comprising:

• a receiving unit configured to receive a first identifier (ID), wherein the first ID is an ID allocated by a first network side device to the terminal device, the terminal device is located in a first area in which the first network side device provides a service, and the first ID is valid in the first area;
• a sending unit configured to indicate mobility information of the terminal device to the first network side device, the mobility information comprising a terminal device mobility attribute indicative of the terminal device being a fixed terminal device or a moveable terminal device;
• the receiving unit is further configured to receive target grant free information indicated by the first network side device, wherein a target grant free resource is a dedicated grant free resource when the terminal device mobility attribute is indicative of the terminal device being the fixed terminal device or a universal grant free resource when the terminal device mobility attribute is indicative of the terminal device being the moveable terminal device, and a target grant free resource type is selected by the first network side device based on the mobility information;
• and
• the sending unit is further configured to send data information to the first network side device based on the target grant free information, wherein data information sent by the sending unit to the first network side device using the dedicated grant free resource comprises data sent by the terminal device, and data information sent by the sending unit to the first network side device using the universal grant free resource comprises data sent by the terminal device and the first ID, wherein
• when the target grant free resource is the dedicated grant free resource, the receiving unit is further configured to receive a valid range of the target grant free resource that is sent by the first network side device, and a first processing unit is configured to determine whether the valid range of the target grant free resource is exceeded,
• when the valid range of the target grant free resource is not exceeded, the sending unit is further configured to send second data information to the first network side device using the dedicated grant free resource, wherein the second data information comprises data sent by the terminal device, and
• when the valid range of the target grant free resource is exceeded, the sending unit is further configured to send third data information to the first network side device using the universal grant free resource, wherein the third data information comprises data sent by the terminal device and the first ID.
