Method for determining RLC Data PDU size in wireless communications system according to control data

摘要

A method of determining a size of Data PDUs of an RLC AM entity includes: (a) utilizing a MAC layer to set a transmission payload size; (b) determining whether the transmission payload size is larger than or equal to at least a Control PDU size; (c) when the transmission payload size is larger than or equal to the Control PDU size, submitting the Control PDU to the MAC layer; (d) adjusting the transmission payload size by subtracting the size of the submitted Control PDU; (e) repeating steps (b), (c) and (d) for all Control PDUs; and (f) utilizing a final adjusted transmission payload size in step (d) to determine a size of a Data PDU.

1. A method of determining a Data Packet Data Unit (PDU) size for a Radio Level Control (RLC) Unacknowledged Mode (UM) or Acknowledged Mode (AM) entity, the method comprising:
utilizing a Media Access Control (MAC) layer to set a transport block size according to a physical layer grant; selecting MAC Control elements to be transmitted in a next transmission opportunity; calculating a total transmission payload as the transport block size minus the sizes of the selected MAC Control elements minus the sizes of corresponding MAC sub-headers of the selected MAC Control elements; setting a transmission payload size according to the total transmission payload; and determining the Data PDU size for the next transmission opportunity according to the set transmission payload size.
