Embodiment Construction

[0023] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0024] method embodiment

[0025] In this embodiment, a physical uplink shared channel processing method is provided, which is used for demodulating and decoding signals in the physical uplink shared channel of the long term evolution system by using a multi-core digital signal processor. figure 1 It is a flowchart of a physical uplink shared channel processing method according to a method embodiment of the present invention.

[0026] Such as figure 1 As shown, the physical uplink shared channel (PUSCH) processing method according to this embodiment includes: step S102, splitting the signal by modulation symbols, and distributing the split signals to multiple cores...

Abstract

The invention discloses a physical uplink channel sharing processing method, including that the signals are split according to the modulation symbol; the split signals are respectively distributed to a plurality of cores of a multi-core digital signal processor for demodulation; for the signals needed to be demodulated, the signals are split according to the corresponding users and / or the code blocks and are distributed to a plurality of cores for demodulation; besides, the invention also discloses a processing device for the physical uplink channel sharing. Based on the technical proposal, under the situation that the maximum air-interface flow is reached, the processing delay is reduced and the processing time is shortened greatly.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a physical uplink shared channel processing method and device. Background technique [0002] According to the long-term evolution (Long-Term Evolution, LTE) protocol on the uplink hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) delay requirements, the enhanced NodeB (eNodeB) after receiving the physical uplink shared channel (PUSCH) channel The time from the subframe to the start of sending a corresponding correct or error (ACK or NACK) response in the downlink is 3ms. [0003] In this way, if the single-core digital signal processor (Digital Signal Processor, DSP) TCI6482 is directly used to serially process uplink demodulation and decoding, after testing, the user terminal (UE) type is Category5, and the transport block (TB) size is 75056bit, the uplink adopts virtual Multiple Input Multiple Output (MIMO), and when the air interface traffi...
