Example Embodiment

[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0054] figure 2 It is a schematic flowchart of a method for sending and processing a downlink control channel in an embodiment of the present invention. The executor of this embodiment is the base station, that is, the sending end, such as figure 2 As shown, the method includes the following steps:

Abstract

The invention provides a transmission processing method and device of a downlink control channel. The transmission processing method comprises steps of performing framing processing on DCI data of a physical downlink control channel PDCCH based on a preset maximum number of PDCCH repetition times; if the frame number of the DCI data after the framing processing is smaller than 8, performing jointencoding according to the frame number of the DCI data and sending the encoded DCI data; and if the frame number of the DCI data after the framing processing is greater than or equal to 8, adopting 8-frame joint encoding and transmitting the encoded DCI data repeatedly by regarding eight frames as a period. By giving consideration to a coverage enhancement problem, the transmission method of the PDCCH is designed again to perform PDCCH transmission periodically; and users with poor coverage can further improve the demodulation performance of the system, improve the coverage performance and further enhance transmission reliability by increasing the number of repetition times.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for sending and processing downlink control channels. Background technique [0002] The transmission processing of the PDCCH (Physical Downlink Control Channel) at the evolved base station (eNB) can be divided into DCI (Downlink Control Information, downlink control information) information construction, coding, scrambling, modulation, and transmission. ,Such as figure 1 shown. Correspondingly, the information processing process of each user's PDCCH receiving end can be divided into information extraction, equalization, deinterleaving, demodulation, descrambling, and blind detection. [0003] However, 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, various industries have rapidly expanded their demand for low-speed, low...
