Abstract

A method for sending control signaling, including: a transmitter using different states of one field in the control signaling to indicate the payload size or RV; and sends the control signaling indicative of the payload size or RV in the field. It is appropriate that some states of one field indicate different payload sizes, and the remaining states of the field indicate different RVs. An apparatus for sending control signaling is disclosed. The apparatus may be integrated in a base station, and may include a control signaling generating unit and a control signaling sending unit.

Claims

1. A method of signaling, comprising:

receiving, by a terminal, control signaling comprising a field, wherein the field includes N bits that are either 1 or 0, and a state of the field is indicated by all the N bits of the field;

wherein N is a positive integer greater than 1;

wherein the field is dynamically indicative of one of a payload size or a Redundancy Version (RV) through the state of the field, wherein the payload size is indicated through a first state of the field when the first state is within a first predetermined range and the RV is indicated through a second state of the field when the second state is within a 10 second predetermined range distinct from the first predetermined range; and

sending, by the terminal, a packet according to the received control signaling to a base station (BS).

2. The method of claim 1, further comprising:

determining, by the terminal, that the RV is a default value if the received control signaling is indicative of the payload size on the field.

3. The method of claim 1, wherein the receiving, by a terminal, control signaling comprises:

receiving, by the terminal, the control signaling indicating the payload size on the field when the terminal receives a packet initially.

4. The method of claim 1, wherein the receiving, by a terminal, a control signaling comprises:

sending, by the terminal, an detecting Discontinuous Transmission (DTX) to the BS;

receiving, by the terminal, the control signaling indicative of the payload size or RV on the field from the BS.

5. The method of claim 4, wherein receiving, by the terminal, the control signaling indicative of the payload size or RV on the field comprises:

receiving, by the terminal, the control signaling indicating the RV on the field of the control signaling to be received next time if a packet transmission count reaches or exceeds a pre-defined value; and

receiving, by the terminal, the control signaling indicating the payload size on the field of the control signaling to be received next time if the packet transmission count does not reach the pre-defined value.

6. The method of claim 1, wherein the control signaling is received by the terminal from the BS.

7. An apparatus of signaling, comprising:

a control signaling receiver, configured to receive control signaling comprising a field from a base station (BS), wherein the field includes N bits that are either 1 or 0, and a state of the field is indicated by all the N bits of the field, wherein N is a positive integer greater than 1;

wherein the field is dynamically indicative of one of a payload size or a Redundancy Version (RV) through the state of the field, wherein the payload size is indicated through a first state of the field in the control signaling when the first state is within a first predetermined range and the RV is indicated through a second state of the field when the second state is within a second predetermined range distinct from the first predetermined range; and

a transmitter, configured to send a packet according to the received control signaling to the BS.

8. The apparatus of claim 7, further comprising

a processor, configured to determine that the RV is a default value if the received control signaling is indicative of the payload size on the field.

9. The apparatus of claim 8, wherein the apparatus is integrated into a terminal.
