Abstract

A communication method, including performing, by a terminal device, in response to a value of a resource bundling granularity being a first-type value, determining at least one resource block bundling group in a scheduling resource corresponding to a terminal device according to the first-type value of the resource bundling granularity, wherein, the first-type value comprises 2 or 4, and receiving, using the at least one resource block bundling group, data transmitted by a network device. The method further includes performing, by the terminal device, in response to the value of the resource bundling granularity being a second-type value, determining a scheduling resource corresponding to the terminal device as a same resource block bundling group, wherein, the second-type value comprises a size of a consecutive scheduling bandwidth of the terminal device, and receiving, using the resource block bundling group, data transmitted by the network device.

determine, when a value of a resource bundling granularity is a first-type value, at least one resource block bundling group in a scheduling resource corresponding to the terminal device based on the first-type value, and receive, through the transceiver, using the at least one resource block bundling group, data transmitted from a network device, wherein the first-type value comprises 2 or 4; and
determine, when the value of the resource bundling granularity is a second-type value, the scheduling resource corresponding to the terminal device as one resource block bundling group, and receive, through the transceiver, using the one resource block bundling group, data transmitted from the network device, wherein, the second-type value comprises a size of a consecutive scheduling bandwidth of the terminal device.

2. The terminal device according to claim 1 , wherein the instructions to determine the at least one resource block bundling group include instructions to perform, when the value of the resource bundling granularity is the first-type value:
determining a first resource block bundling group in the scheduling resource corresponding to the terminal device, wherein the first resource block bundling group comprises first PRBbundling first resource blocks in the scheduling resource, and wherein PRBbundling first and the value of the resource bundling granularity satisfy:
PRBbundling first =P−N mod P
