Problems solved by technology

However, when the service bandwidth exceeds 1M, due to the limited cyclic shift of the sequence in this design, the number of subbands with the same phase pilot increases, making the signal peak-to-average ratio of the broadband service larger, which will increase the complexity of the system design

Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0027] The present invention proposes a method for generating a pilot sequence of a PUSCH channel of a multi-subband system, such as figure 1 As shown, the method includes the following steps:

[0028] Step 101: Obtain a long ZC sequence as a pilot sequence according to the number of subbands in the occupied bandwidth.

[0029] The "long ZC sequence" mentioned in this application is compared with the existing ZC sequence. The existing ZC sequence is generated according to the width of a single sub-band, but this application is generated according to the number of sub-bands occupying the bandwidth.

[0030] Step 102: segment the long ZC sequence into A small sequence is used as the pilot frequency of each subband, where, is the number of subba...

Abstract

The invention discloses a method for generating pilot sequences of a multi-sub-band system. The method comprises the steps of: firstly, acquiring a first pilot sequence according to a sub-band numberin a bandwidth occupied by the system; and secondly, segmenting the first pilot sequence into M<RB><PUSCH> small sequences, and regarding the small sequences as pilots of sub-bands, wherein the M<RB><PUSCH> is the sub-band number. By applying the method disclosed by the invention, a peak-to-average ratio of a pilot signal does not increase due to the increase of the bandwidth, thereby reducing thecomplexity of the system design.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to a method for generating a pilot sequence of a multi-subband system. Background technique [0002] With the continuous development of new wireless communication technologies, as well as the vigorous development of the mobile Internet and the Internet of Things industry, the demand for wireless broadband services such as video surveillance and live video broadcasting in various industries has expanded rapidly. How to better aggregate multiple discrete narrowbands to support broadband service requirements has become a focus of attention. [0003] There is an existing pilot sequence design scheme for the physical uplink shared channel (PUSCH) of a private network system, which utilizes a short ZC sequence on a single subband to be cyclically extended to multiple subbands to support broadband service requirements. However, when the service bandwidth exceeds 1M,...
