Problems solved by technology

[0005] However, when determining the spatial information of the PUSCH scheduled by DCI0_0, the above method does not take into account the consistency between the path loss reference signal and the reference signal representing the spatial information, so that the path loss reference signal is different from the reference signal representing the spatial information, thus affecting system performance

Abstract

The invention relates to a method and a device for determining the spatial information. The method comprises the following steps: collecting downlink control information (DCI) for scheduling a data channel; according to the DCI, determining spatial information of the data channel according to a reference signal type related to the data channel or a TCI state parameter of the data channel. According to the spatial information determination method and device provided by the embodiment of the invention, the spatial information can still be ensured to be normally determined under the condition that the current spatial information determination mode cannot be applied due to the change of the type of the reference signal related to the data channel.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for determining spatial information. Background technique [0002] NR supports beam-based transmission to improve system performance; specifically, the beam is characterized by a reference signal corresponding to spatial information or a reference signal corresponding to QCL-TypeD in TCI. [0003] In Rel-15, for the PUSCH scheduled by DCI0_0, because DCI0_0 does not contain information indicating the spatial information of the PUSCH, the protocol stipulates that the spatial information of the PUSCH scheduled by DCI0_0 corresponds to the PUCCH resource with the smallest ID of the active BWP of the cell where the PUSCH is located spatial information. [0004] The Rel-16 protocol further regulates the default spatial information of the PUSCH scheduled by DCI0_0. Specifically, if the active BWP of the cell where the PUSCH is located does not configur...
