Problems solved by technology

However, due to the high bandwidth, multiple antennas, and high throughput of LTE, the processing delay will be very obvious during transmission, making it difficult for the entire L1 (layer 1) processing delay to meet the system requirements.

Embodiment Construction

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and unnecessary details and functions for the present invention will be omitted during the description to avoid confusing the understanding of the present invention.

[0017] Embodiments of the present invention propose layer 1 baseband processing devices, such as figure 1 As shown, the apparatus at least includes: a resource inverse mapping unit 120, configured to perform resource inverse mapping on one symbol of one antenna, and transmit one pilot symbol (pilot symbol) of one antenna each time. The channel estimation unit 130 performs signal estimation according to the received pilot symbol of one antenna, and transmits data related to one user at a time. The equalization unit 140 equalizes the data related to one user each time, and sends the processed data related to one user each time, wherein the data related to one user includes the da...

Abstract

The present invention discloses a layer1 baseband processing method and a device, wherein the method comprises the steps of: performing resource inverse transformation on a signal subjected to fast Fourier transformation with every antenna every symbol as one unit, performing channel estimation on pilot symbols subjected to the resource inverse transformation with every antenna every pilot symbol as one unit, performing equalization on data related to one user every time, wherein the data related to one unit comprises data symbols subjected to the resource inverse transformation and pilot symbols used for channel estimation; performing bit-level processing on the equalized data related to one user every time, wherein each level operation sends data to next level operation with a data volume processed by the next level operation every time as the unit. The technical scheme provided by the invention can reduce processing time-delay of each processor in a multiprocessor baseband processing system, and then reduces the processing time-delay of the whole baseband processing system.

Description

technical field [0001] Embodiments of the present invention generally relate to the field of baseband processing, and more specifically, relate to a layer 1 baseband processing method and device thereof. Background technique [0002] At present, there are mainly two types of LTE baseband processing system solutions: 1) Single-chip multi-core. This solution consumes a lot of power and is difficult to dissipate heat, and is limited by the processing speed of the chip, making it difficult to improve performance. 2) Multi-processors are used, and high-speed buses are used to interact between processors. Since Long-Term Evolution (LTE) requires high uplink and downlink throughput and multiple antennas, the amount of data interaction between processors is very large, and the transmission delay is very large, making it difficult to improve the processing capacity of the entire baseband system. [0003] The second solution is a hotspot of the LTE baseband processing system. Takin...
