Abstract

The invention discloses an E-DCH transport format combination (E-TFC) selection method and a system. The method comprises the steps: calculating a power maximum value beta 0, e-max according to an authorized power Parant given by a network; calculating a code rate maximum value lambada 0, e-max corresponding to the power maximum value beta 0; comparing the code rate maximum value lambada 0, e-max with a minimum code rate lambada n w-min configured by a network side, and confirming a maximum transmission code block index TB index and a minimum transmission code block index TB index according to a comparative result; and confirming size and sending power of a final transmission code block. The E-TFC selection method and the system optimize existing E-TFC selection, effectively reduce time complexity of correlation calculations, and reduce million instructions per second (MIPS) consumption in an E-TFC selection process.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for selecting E-TFC. Background technique [0002] The selection process of Enhanced Dedicated Control Channel Transport Format Combination (E-DCH Transport Format Combination, E-TFC) in high speed uplink packet access (HSUPA) is relatively complicated, how to reduce the E-TFC selection process The consumption of millions of machine language instructions (Millions Instructions Per Second, MIPS) processed per second is undoubtedly of great significance to the increasing data throughput. [0003] The existing E-TFC selection is realized according to the provisions of the 25321 line standard. Its main process includes: Step 1, decide set B. The set is a set of logical channels, including a) the highest priority logical channel with data waiting to be transmitted; b) a set of logical channels with data to be sent that can be multiplexed with the logical channel selected in a). S...
