Problems solved by technology

[0003] However, the network side cannot notify the UE of the corresponding rate matching method at any time, so the multiplexing of PDSCH, CSI-RS, TRS and other signals cannot be multiplexed through the above notification method
For example, for paging, SIB and other multicast or broadcast signals carried on PDSCH, UEs in the idle state need to receive them, but it is difficult to notify these UEs that they need to match the CSI-RS, TRS and other signals that have been configured for other UEs, so It will cause collision between signals, which will lead to signal interference and other phenomena.

Embodiment 1

[0076] image 3 It is a method flowchart of a resource multiplexing method in the first embodiment of the present application. Such as image 3 As shown, the method includes the following steps:

[0077] In step S301, the network device determines that the data signal and the reference signal need to be transmitted on the same time-frequency resource.

[0078] Step S302, the network device discards the reference signal, and sends notification information for indicating that the reference signal is discarded to the second terminal device for receiving the reference signal.

[0079] Step S303, the network device transmits the data signal to the first terminal device through the time-frequency resource.

[0080] Step S304, the first terminal device receives the data signal from the network device, and directly demodulates the data signal.

[0081] In the first embodiment, the network device always considers that the priority of the data signal is higher than that of the refer...

Embodiment 2

[0083] Figure 4 It is a method flowchart of a resource multiplexing method in the second embodiment of the present application. Such as Figure 4 As shown, the method includes the following steps:

[0084] In step S401, the network device determines that the data signal and the reference signal need to be transmitted on the same time-frequency resource.

[0085] In step S402, the network device punctures the data signal, and fills the vacant position formed by the puncturing in the data signal with the reference signal.

[0086] Step S403, the network device transmits the reference signal and the data signal to the first terminal device through the same time-frequency resource, and sends notification information for indicating that the data signal is punctured to the first terminal device. Wherein, the notification information includes the position information of the vacant position formed after the data signal is punched.

[0087] Step S404, the first terminal device rec...

Abstract

The embodiment of the present application discloses a resource multiplexing method and device, so as to realize multiplexing of data signals and reference signals on the same time-frequency resource. The method includes: determining whether the data signal and the reference signal need to be transmitted on the same time-frequency resource, the target receiving device of the data signal is a first terminal device, and the target receiving device of the reference signal is a second terminal device; if It is determined that the data signal and the reference signal need to be transmitted on the same time-frequency resource, and the data signal and / or the reference signal are processed. The technical solution realizes the multiplexing of the data signal and the reference signal on the same time-frequency resource, and solves problems such as signal interference caused by the collision between the data signal and the reference signal.

Description

technical field [0001] The present application relates to the communication field, and in particular to a resource multiplexing method and device. Background technique [0002] For the future-oriented fifth-generation (5Generation, 5G) mobile communication system, in order to achieve the goal of a downlink transmission rate of 20Gbps and an uplink transmission rate of 10Gbps, high-frequency transmission technology and large-scale antenna array technology have attracted much attention. During data transmission, the network side divides the time-frequency resources into a grid, and allocates resources to UEs (User Equipment, user equipment) according to RB (Resource Block, resource block) for data transmission. At the same time, there are many reference signals, such as CSI-RS (Channel State Information Reference Signal), TRS (Tracking Reference Signal), etc. These reference signals do not need to completely occupy all resources in RB, so they are allocated to PDSCH (Physical ...
