Embodiment approach 1

[0070] Such as Figure 5 As shown, in this preferred embodiment, the length and content of the UW, the length and the modulation mode of the DATA are all unchanged, that is, there is only one data frame structure, and no CP is added to the UW of the data frame.

[0071] Preferably, the number of segments of the random sequence (that is, the number of repetitions n) can be configured to different but uniform values, for example: the number of repetitions can be 2, 3, 4, etc. The random sequence can also be PN, Golay, Zadoff-Chu, etc. In any form, the length of the random sequence can also be configured according to the actual situation. The length and modulation mode of the DATA part can also be configured according to actual needs. For example, the specific configuration parameters can be configured in accordance with Table 1:

Embodiment approach 3

[0081] Such as Figure 7 As shown, in the preferred embodiment, three data frames are included, and each data frame includes T BLKs. Among them, the UW of the first data frame is composed of two PN sequences plus CP, the UW of the second data frame is composed of three ZC sequences, and the UW of the third data frame is composed of three Ga32 (Golay sequences) plus CP. . The specific configuration parameters can be configured in accordance with Table 3:

Abstract

Disclosed are methods and apparatuses for sending data and receiving data. The method for sending data comprises: encapsulating to-be-sent data to obtain one or more data frames, the foregoing data frames comprising a data information block and a special word arranged in a spaced manner and the foregoing special word being formed by one or more repeated pseudo random sequence; and sending the foregoing one or more data frames. By means of the present invention, the technical problem is solved that a data sending method in a related technology cannot be used in a connection-oriented communications scenario, and technical effects of functions such as rapid capture, carrier synchronization, channel estimation, data protection and phase tracking are achieved.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for data transmission and data reception. Background technique [0002] E-band includes two unchannelized frequency bands: 71-76GHz and 81-86GHz. Compared with other frequency bands, E-band frequency band has very significant advantages, mainly in the following two aspects: [0003] 1) The frequency band is 10GHz, which is almost 50 times the entire frequency band of various low-frequency mobile communication services, and is much higher than the widely used microwave frequency band. Such a wide frequency band makes a new generation of wireless high-speed transmission possible. [0004] 2) Generally, the lower frequency microwave frequency spectrum will be subdivided very finely. For example, in the United States, the FCC divides each microwave band into a series of sub-bands not exceeding 50MHz. This fine division ultimately limits the channel Data through...
