Embodiment 2

[0072] The technical solution in the second embodiment is relatively simple and easy to implement, but it also brings some problems. such as in Figure 6 Among them, for PUSCH resource allocation type Type 0, if the scheduling subbands allocated by PUSCH are discontinuous, according to the technical solution in Embodiment 2, scheduling subband 0 and scheduling subband 12 will correspond to the same precoding indication I 0 . However, since the frequency domain distance between the scheduling subband 0 and the scheduling subband 12 is too far, and the channel difference is too large, using the same precoding indication will bring performance loss. In order to solve the above problems, the third embodiment of the present invention proposes a method for allocating and scheduling subbands, such as Figure 7 As shown, the method specifically includes the following steps:

Abstract

The invention discloses a method, device and equipment for distributing scheduling subbands and a readable storage medium. The method comprises the following steps: receiving downlink control information (DCI) sent by a base station, and determining scheduling subbands in a physical uplink sharing channel (PUSCH); and establishing a corresponding relation between precoding indications in the DCI and the scheduling subbands in the PUSCH according to at least one parameter of the total number of the scheduling subbands in the PUSCH and a total frequency domain distance of the scheduling subbandsin the PUSCH and the total number of the precoding indications in the DCI. The method solves the problem on indication transmission of precoded information of the uplink scheduling subbands, and theprecoded information of the uplink scheduling subbands at a dynamically changing number is informed through fixed precoding indications in the DCI.

Description

technical field [0001] The present invention relates to the technical field of uplink transmission, in particular to a method, device, equipment and readable storage medium for allocating and scheduling subbands. Background technique [0002] At present, for uplink transmission, including codebook-based transmission (Codebook Based) and non-codebook-based transmission (Non-codebook Based), NR (New Radio, new wireless technology) only supports DCI (Downlink Control Information, downlink control information) Indicates the precoding indication in to notify the wideband precoding information. For users with relatively strong channel frequency selectivity, the precoding indication will bring performance loss. However, there is no good solution for how to indicate the precoding information of the uplink scheduling subbands. Contents of the invention [0003] The main purpose of the present invention is to propose a method, device, device, and readable storage medium for alloca...
