Wireless communication method and device that conditionally operates based on a length indicator type

1. A wireless communication method, comprising:

determining, by a user equipment (UE), that a length of an radio link control (RLC) service data unit (SDU) or RLC SDU segment is greater than a threshold;

determining, by the UE, a type of length indicator which is allocated by a network; and

determining, by the UE, to force to map the RLC SDU or RLC SDU segment to the end of an RLC protocol data unit (PDU) if the type of the length indicator is a first type,

wherein the first type is 11-bit length indicator and a second type is 15-bit length indicator.

2. The wireless communication method of claim 1 , further comprising:

not forcing to map the RLC SDU or RLC SDU segment to the end of the RLC PDU if the type of the length indicator is the second type,

wherein a first length of the first type of the length indicator is shorter than a second length of the second type of the length indicator.

3. The wireless communication method of claim 1 , wherein the threshold is 2047 bytes.

4. A wireless communication method, comprising:

determining, by a user equipment (UE), a type of length indicator which is allocated by a network;

determining, by the UE, whether a length of a radio link control (RLC) service data unit (SDU) or RLC SDU segment is greater than a threshold if the type of the length indicator is a 11 bit length indicator; and

forcing to map the RLC SDU or RLC SDU segment to the end of a RLC protocol data unit (PDU) when the length of the RLC SDU or RLC SDU segment is greater than the threshold.

5. The wireless communication method of claim 4 , further comprising:

not forcing to map the RLC SDU or RLC SDU segment to the end of the RLC PDU when the length of the RLC SDU or RLC SDU segment is not greater than the threshold.

6. A wireless communication device, comprising:

a processor, configured to determine that a length of an radio link control (RLC) service data unit (SDU) or RLC SDU segment is greater than a threshold, determine a type of the length indicator which is allocated by a network and determine to force to map the RLC SDU or RLC SDU segment to the end of an RLC protocol data unit (PDU) if the type of the length indicator is a first type, wherein the first type is 11-bit length indicator and a second type is 15-bit length indicator.

7. The wireless communication device of claim 6 , wherein the processor does not force to map the RLC SDU or RLC SDU segment to the end of the RLC PDU if the type of the length indicator is the second type, and wherein a first length of the first type of the length indicator is shorter than a second length of the second type of the length indicator.

8. The wireless communication device of claim 6 , wherein the threshold is 2047 bytes.

9. A wireless communication device, comprising:

a processor, configured to determine a type of length indicator which is allocated by a network, determine whether a length of a radio link control (RLC) service data unit (SDU) or RLC SDU segment is greater than a threshold if the type of the length indicator is a 11-bit length indicator, and forces to map the RLC SDU or RLC SDU segment to the end of a RLC protocol data unit (PDU) when the length of the RLC SDU or RLC SDU segment is greater than the threshold.

10. The wireless communication device of claim 9 , wherein the processor does not forcing to map the RLC SDU or RLC SDU segment to the end of the RLC PDU when the length of the RLC SDU or RLC SDU segment is not greater than the threshold.
