17 Claims

1. A frequency domain resource allocation method, comprising:

determining M frequency domain resources, wherein M is an integer greater than 1, any two of the M frequency domain resources do not overlap, each of the M frequency domain resources is associated with one piece of quasi-colocation (QCL) information, and any two of the M frequency domain resources are associated with different QCL information; and

sending or receiving data on one or more of the M frequency domain resources, wherein:

when a precoding resource group (PRG) size is 2 or 4, the M frequency domain resources are determined by using a PRG as a frequency domain resource allocation unit, wherein determining the M frequency domain resources comprises determining an m^thfrequency domain resource in the M frequency domain resources, wherein the m^thfrequency domain resource comprises an (M*i+m)^thfrequency domain resource allocation unit in N frequency domain resource allocation units comprised in scheduled bandwidth of a terminal device, the scheduled bandwidth is bandwidth comprising at least one PRB used for data transmission, N is a positive integer, m is an integer greater than 0 and less than or equal to M, and i=0, 1, . . . ,

when a PRG size is wideband, the M frequency domain resources are determined by using

physical resource blocks (PRBs) as a frequency domain resource allocation unit, wherein W is a quantity of PRBs comprised in scheduled bandwidth of a terminal device, and W is an integer greater than 1.
