Problems solved by technology

However, these coprocessors are all designed for system equipment. Due to the difference in the solution rate matching method between the receiving side of the terminal equipment and the receiving side of the system equipment, the coprocessor cannot support the downlink solution rate matching method, and the terminal equipment cannot directly adopt

Abstract

The present invention discloses an LTE downlink de-rate matching method and device; obtaining invalid soft information by means of calculating the number of dummy elements; filling in the obtained invalid soft information at a location corresponding to data to be de-rate matched; using a de-rate matching module to de-rate match data awaiting de-rate matching, said data having been filled in with invalid soft information.

Description

technical field [0001] The present invention relates to the communication field, in particular to a long term evolution technology LTE (LTE: Long Term Evolution) downlink de-rate matching method and device. Background technique [0002] The 3rd Generation Partnership Project (3GPP) proposes the Long Term Evolution (LTE) of the 3GPP air technology. The LTE system needs to support multi-antenna technology with lower delay, higher user data rate, larger system capacity, larger coverage and lower cost. In order to meet its flexible transmission requirements for various real-time services, broadcast and multicast services, and to achieve the bit rate required by the transmission format during channel mapping to match the carrying capacity of the physical channel, the LTE system adopts rate matching (Rate matching) technology. [0003] Rate matching means that the bits on the transmission channel are repeated (repeated) or punctured (punctured). Punching is to knock out the cur...
