Problems solved by technology

However, multiple consecutive time slots are allocated PDSCH resources at the same position in the bandwidth, and the multipath effect of the wireless environment causes channel fading
The frequency domain positions of the PDSCH resources in multiple consecutive time slots are the same, which will easily cause the PDSCH to experience the same condition of channel fading in the frequency domain, and reduce the probability that the user equipment (UE) will successfully demodulate the PDSCH in an unfavorable channel environment

Embodiment Construction

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0057] A resource allocation method, the method comprising: determining a first frequency domain position of a resource in a first time slot in a plurality of aggregated consecutive time slots; An offset strategy, determining the second frequency domain position of the resource in the second time slot after the first time slot; according to the frequency domain position of the resource in each time slot of the plurality of consecutive time slots, assigning the PDSCH to the terminal resource.

Abstract

The invention discloses a resource allocation method and device and a storage medium. The method comprises the following steps: determining a first frequency domain position of a resource in a first time slot in a plurality of aggregated continuous time slots; determining a second frequency domain position of a resource in a second time slot after the first time slot according to the first frequency domain position and a preset frequency domain position offset strategy; and allocating the PDSCH resource to the terminal according to the frequency domain position of the resource in each time slot of the plurality of continuous time slots, so that the channel gain of the PDSCH can be reduced and improved, and the success rate of demodulating the PDSCH by the terminal in an unsatisfactory channel environment is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a resource allocation method, device and storage medium. Background technique [0002] PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) in NR (New Radio, New Radio) supports the transmission mode of time slot aggregation to obtain downlink coverage gain. This is mainly aimed at cell edge users to improve the reliability of data transmission. [0003] After time slot aggregation is configured, PDSCH uses the same time slot allocation for transmission. In multiple consecutive time slots, the content of each time slot transmission is the same, and the TB (Transport Block, transmission block) of PDSCH is redundant. The remaining version (RV, Redundancy Version) changes cyclically. [0004] The PDSCH time slot aggregation in the prior art increases the reliability of PDSCH transmission under non-ideal conditions by repeatedly sending an...
