Embodiment 1

[0020] The technical solution of the embodiment of the present invention is applied between the sending end and the receiving end (terminal). After the sending end determines the precoding method according to the type of the control channel, it then performs precoding processing on the data of the control channel according to the determined precoding method , after the receiving end receives the processed data, since the receiving end already knows the type of the control channel, the terminal can know the precoding method adopted by the sending end.

[0021] In this embodiment, a data precoding processing method is provided, which can also be understood as a control channel precoding processing method, figure 1 is a flowchart of a data precoding processing method according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0022] Step S102, the transmitting end determines a precoding method according to the type ...

Embodiment 2

[0063] In this embodiment, a data precoding processing device is also provided, and the device is used to realize the above embodiments and preferred implementation modes, and what has already been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0064] figure 2 is a structural block diagram of a data precoding processing device according to an embodiment of the present invention, such as figure 2 As shown, the device includes:

[0065] A determining module 20, configured to determine a precoding method according to the type of the control channel, the precoding method at least including one of the following: predefined precoding, feedback precoding;

[0066] The ...

Embodiment 3

[0137] Preferred embodiment 3 of the present invention provides a precoding matrix indication method, which is applied to the physical control channel of the user-specific search space, and the method includes:

[0138] The control signaling is sent through the control channel, and the control signaling instructs the next control channel to use the codebook corresponding to the latest PMI fed back by the receiving end or use the codebook corresponding to the second predefined precoding. After receiving the control signaling, the receiving end can determine the precoding matrix used by the MPDCCH.

[0139] Specifically, the signaling sent by the Kth control channel indicates the information of the precoding matrix used by the K+1th control channel, and K is greater than or equal to 1. After receiving the control signaling sent by the Kth control channel, the receiving end uses the precoding matrix information indicated by the signaling to demodulate the data of the time-frequen...

Abstract

The invention provides a data pre-coding processing method and device and a storage medium, and the method comprises the steps: determining a pre-coding mode according to the type of a control channel, and the pre-coding mode at least comprises one of the following modes: predefined pre-coding and feedback pre-coding; and pre-coding the data of the control channel according to the pre-coding mode.By adopting the technical scheme, the problem that a sending end adopts which encoding mode to pre-encode the data of the control channel in related technologies is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data precoding processing method and device, and a storage medium. Background technique [0002] In Machine Type Communication (Machine Type Communication, MTC), an MTC-Physical Downlink Control Channel (MTC-Physical Downlink control channel, MPDCCH) transmits data in a precoded manner. In Release-15 version of MPDCCH, the receiving end adopts channel estimation based on Demodulation Reference Signal (DMRS); in Release-16 version, in order to enhance the performance of MPDCCH, the receiving end can use cell-specific reference signal (Cell- specific Reference Signal, CRS) and DMRS joint channel estimation. However, joint channel estimation using CRS and DMRS requires the receiving end to know the precoding matrix information used by the sending end. Therefore, how the transmitting end precodes the data of the control channel so that the terminal can know the precoding inform...
