Abstract  Abstract

One is used for in a kind of method and device for E-TFC selection of MAC PDU before construction of RLC PDU the MAC PDU comprises using the or these RLC PDUS. The device is arranged to generate predicted in transmission and used for one TTI after the RLC PDUS. RLC PDU if any will be include in MAC PDU and must be in the E-TFC selection after construction is later in determining the size of the MAC PDU so the method avoids one of the inherent delay limit caused by the large peak value processing needed. The method and device maintain of RLC PDU size and the similar match between MAC PDU includes the RLC PDU of size. Maintain the similar matching the one of HARQ remaining error caused by the RLC PDU error rate compare maintain low. The method can be set as half can radio perceptible or with delay of radio may perceive.

A method and apparatus are used to create RLC PDUs in advance of the E-TFC selection for the MAC PDU that will include this or these RLC PDU(s). The apparatus may be configured to pre-generate RLC PDUs for transmission in a later TTI. This approach avoids the large peak processing requirement due to the tight delay constraint if any RLC PDU to be included into a MAC PDU had to be created after the determination of the size of this MAC PDU i.e. after E-TFC selection. The method and apparatus maintain an approximate match between the size of an RLC PDU and the size of the MAC PDU it is included into. Maintaining this approximate match ensures that the RLC PDU error rate due to HARQ residual errors remains low. This approach may be designed as semi-radio aware or radio-aware with delay.
