Method and apparatus for processing control signaling information

Abstract

The invention discloses a method and a device for processing control signaling information, wherein the method for processing the control signaling information comprises the steps of conducting forward error correction coding for the control signaling information; conducting serial-parallel conversion for a control signaling information coding block generated by the forward error correction coding; dividing the control signaling information coding block into a plurality of parallel coding blocks; conducting spectrum spreading, modulation and orthogonal frequency division multiplexing sub-carrier mapping in sequence for the plurality of parallel coding blocks. The embodiment of the invention conducts spreading gain for the control signaling information; through the serial-parallel conversion and the orthogonal frequency division multiplexing sub-carrier mapping, the control signaling information distributes on different sub-carrier segments, thereby realizing frequency diversity, improving correct reception and recognition of a terminal for the control signaling information, and improving the reliability of a system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for processing control signaling information. Background technique [0002] In each communication system, it is necessary to broadcast system messages to provide basic information for terminals to access and connect to the communication system, and the system messages are called control signaling. According to different recipients, control signaling can be divided into common control signaling and dedicated control signaling. The common control signaling is a signaling message that all terminals need to receive, and the dedicated control signaling is a signaling message for a specific single or a group of terminals. [0003] Due to the difference in receiving objects, there may be a large difference in transmission methods between public control signaling and dedicated control signaling. Dedicated control signaling is aimed at a single terminal or a gr...

Problems solved by technology

[0009] According to the requirements of the 802.16m standard, it is necessary to support the mobile speed of the terminal up to 350 km / h. According to the technical specifications of the 802.16e standard, the maximum mobile speed of the terminal supported by the 802.16e system is only 120 km / h. If the terminal Moving beyond the maximum moving speed of 120 km / h, the channel between the terminal and the processing device for controlling signaling information will show strong time-varying characteristics, and the original pilot density cannot effectively track the time-varying channel. As a result, the processing device for control signaling information cannot effectively compensate the channel, resulting in an increase in the bit error rate or packet error rate of transmitted data, which will affect the terminal's correct reception and identification of control signaling information, thereby affecting the terminal's communication services. The correct reception of data information causes the terminal to fail to perform normal communication services
