Resource reuse method and device

Abstract

The embodiment of the invention discloses a resource reuse method and device which achieve reuse of data signals and reference signals in the same time-domain resource. The method comprises the stepsof: determining whether the data signals and the reference signals are required being transmitted on the same time-domain resource or not, wherein a target receiving device of the data signals is a first terminal device, and a target receiving device of the reference signals is a second terminal device; if it is determined that the data signals and the reference signals are required being transmitted in the same time frequency resource, the data signals and / or the reference signals are processed. The technical scheme achieves reuse of the data signals and the reference signals in the same timefrequency resource so as to solve the problems of the signal interference caused by collision of the data signals and the reference signals.

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 ...

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.
