Embodiment Construction

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] Such as figure 1 As shown, it is a flow chart of the base station side data compression method of the present invention, and this embodiment includes the following steps:

[0021] Step S001: RRU receives uplink data;

[0022] Step S002: delete all CP information in the above-mentioned uplink data;

[0023] The CP information includes pre-CP information and post-CP information.

[0024] Step S003: Send the above uplink data to the BBU.

[0025] Such as figure 2 Shown is a schematic diagram of an OFDM symbol in the time domain, where a is the...

Abstract

The invention relates to a base station and an uplink data compression method on a base station side. The base station comprises a RRU (radio remote unit) and a BBU (base band unit). The uplink data compression method on the base station side comprises the step of deleting CP (cyclic prefix) information of each OFDM (orthogonal frequency division multiplexing) symbol in uplink data by the RRU before the received uplink data are sent to the BBU. The uplink data compression method on the base station side reduces the data volume of the uplink data, so that speed of an optical interface is reduced, the speed increase of a communication system device is decreased, and the operation cost is lowered.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a base station and a data compression method at the base station side. Background technique [0002] Data compression refers to a technical method to reduce the amount of data to reduce storage space and improve its transmission, storage and processing efficiency without losing information, or to reorganize data according to a certain algorithm to reduce data redundancy. and storage space. Data compression includes lossy compression and lossless compression. Lossy compression takes advantage of the fact that humans are not sensitive to certain frequency components in images or sound waves, allowing certain information to be lost during the compression process; although the original data cannot be completely restored, the lost part has a greater impact on understanding the original image. Small, in exchange for a larger compression ratio. Lossy compression is widely used i...
