US 11,445,536 B2 · Downlink control information transmission method

Abstract

An embodiment of this application provides a downlink control information transmission method and an apparatus. The method includes: receiving first downlink control information DCI in search space of a first carrier bandwidth part BWP, where if a frequency domain resource allocation type of the first BWP is a type 0, an Lf-bit frequency domain resource allocation indication in the first DCI is an Lf-bit bitmap, and bits in the Lf-bit bitmap in descending order are respectively corresponding to resource block groups RBG 0 to RBG (Lf−1) in a second BWP; and for one bit in the Lf-bit bitmap, when a value of the bit is t1, an allocated resource includes one RBG corresponding to the bit.

A method, comprising:

receiving, by a device, first downlink control information (DCI) through a first bandwidth part (BWP), wherein the first DCI comprises a BWP indication and a first frequency domain resource allocation indication, and a second BWP is indicated by the BWP indication;
and
in response to a first resource allocation type and a second resource allocation type being configured for the second BWP, and in response to a size of an information field of the first frequency domain resource allocation indication being less than a size of an information field of a second frequency domain resource allocation indication, indicating, by the first frequency domain resource allocation indication, a frequency domain resource in the second BWP through the first resource allocation type, and the second frequency domain resource allocation indication is receivable in the second BWP to indicate the frequency domain resource in the second BWP.

An apparatus, comprising:

a non-transitory memory;
and
a processor coupled to the non-transitory memory, wherein processor is configured to:
receive first downlink control information (DCI) through a first bandwidth part (BWP), wherein the first DCI comprises a BWP indication and a first frequency domain resource allocation indication, and a second BWP is indicated by the BWP indication;
and
in response to a first resource allocation type and a second resource allocation type being configured for the second BWP, and in response to a size of an information field of the first frequency domain resource allocation indication being less than size of an information field of a second frequency domain resource allocation indication, indicate, by the first frequency domain resource allocation indication, a frequency domain resource in the second BWP through the first resource allocation type, and the second frequency domain resource allocation indication receivable in the second BWP to indicate the frequency domain resource in the second BWP.
