Abstract

A data transmission, by a terminal device, is described that improves data transmission efficiency while ensuring a transmission latency. The data transmission method includes sending a first transport block to a radio access device for X times by using a shared resource that is configured by the radio access device for at least one terminal, where the terminal is one of the at least one terminal, and X>0. The method further includes determining a dedicated resource allocated by the radio access device to the terminal, and sending the first transport block to the radio access device for Y times by using a target resource. The target resource includes the dedicated resource, and Y≥0.

First claim

What is claimed is:

1. A data transmission method by a terminal, the method comprising:
sending a first transport block to a radio access device for X times, by using a shared resource, wherein X is an integer >0, wherein the first transport block that is sent by the terminal using the shared resource is inserted with a hybrid automatic repeat request (HARQ) process identifier for transmitting the first transport block each particular time of the X times and a new data indicator (NDI) for the particular time of the X times, and wherein the NDI indicates whether the first transport block comprises new data or retransmitted data;
determining a dedicated resource that is allocated for the terminal by the radio access device; and
sending the first transport block to the radio access device for Y times by using the dedicated resource, wherein Y is an integer >0.

2. The method according to claim 1 , wherein the sending the first transport block to the radio access device for Y times by using the dedicated resource comprises:
sending the first transport block for Y times by using the dedicated resource within a transmission time unit,
wherein the transmission time unit comprises:
the dedicated resource, and
the shared resource.

3. The method according to claim 1 , wherein the shared resource is:
a radio resource allocated by the radio access device, and
shared with at least one terminal.

4. The method according to claim 1 , wherein the shared resource is a radio resource without a dynamic grant from the radio access device.

5. The method according to claim 1 , wherein the shared resource is located within each of Z transmission time units and where Z≥X, and
wherein the method further comprises:
obtaining a transmission request of a second transport block within an M th transmission time unit in the Z transmission time units; and
sending, in accordance with the obtaining, the first transport block within the M th transmission time unit using the shared resource within the M th transmission time unit, wherein the M th transmission time unit is a transmission time unit, other than the first transmission time unit, in the Z transmission time units.

6. The method according to claim 1 , wherein the determining the dedicated resource allocated by the radio access device for the terminal comprises:
receiving a resource allocation information sent by the radio access device,
wherein the resource allocation information indicates the dedicated resource required for sending the first transport block;
wherein the resource allocation information comprises second indication information, and
wherein the second indication information instructs the terminal to repeatedly send the first transport block transmitted within a transmission time unit K, where K≥0.

7. An apparatus, comprising:
a transmitter, and
a processor; and
a non-transitory computer-readable medium including computer-executable instructions that, when executed by the processor, facilitate performing a method comprising:
sending, by the transmitter cooperatively operating with the processor, a first transport block to a radio access device for X times by using a shared resource, wherein X is an integer >0, the first transport block that is sent using the shared resource is inserted with a hybrid automatic repeat request (HARQ) process identifier for transmitting the first transport block each particular time of the X times and a new data indicator (NDI) for each particular time of the X times; wherein the NDI indicates whether the first transport block comprises new data or retransmitted data;
determining, by the processor, a dedicated resource that is allocated for the apparatus by the radio access device; and
sending, by the transmitter cooperatively operating with the processor, the first transport block to the radio access device for Y times by using the dedicated resource, wherein Y is an integer >0.

8. The apparatus according to claim 7 , wherein the method further comprises:
sending, by the transmitter cooperatively operating with the processor, the first transport block for Y times by using the dedicated resource within a transmission time unit,
wherein the transmission time unit comprises both:
the dedicated resource, and
the shared resource.

9. The apparatus according to claim 7 , wherein the shared resource is:
a radio resource allocated by the radio access device, and
shared with at least one terminal.

10. The apparatus according to claim 7 , wherein the shared resource is a radio resource without a dynamic grant from the radio access device.

11. The apparatus according to claim 7 , wherein the shared resource is located within each of Z transmission time units, and where Z≥X; and
wherein the method carried out on the apparatus comprises:
obtaining a transmission request of a second transport block within an M th transmission time unit in the Z transmission time units; and
sending, in accordance with the obtaining by the transmitter cooperatively operating with the processor, the first transport block within the M th transmission time unit using the shared resource within the M th transmission time unit wherein the M th transmission time unit is a transmission time unit, other than the first transmission time unit, in the Z transmission time units.

12. The apparatus according to claim 7 , wherein the transmitter is further configured, during the determining the dedicated resource allocated by the radio access device for the apparatus to:
receive a resource allocation information sent by the radio access device,
wherein the resource allocation information indicates the dedicated resource required by the apparatus for sending the first transport block,
