Claim 4:
5. A resource allocation method, comprising:
determining, by a base station based on a physical cell identity (PCID) of a first cell and a preset rule, a first subcarrier group corresponding to a first terminal device in the first cell, wherein the first subcarrier group corresponding to the first terminal device comprises one or more subcarriers in a subcarrier set corresponding to the first terminal device;
wherein the first terminal device corresponds to at least two candidate subcarrier groups, and each candidate subcarrier group comprises a plurality of consecutive subcarriers; and
wherein:
the first terminal device corresponds to two candidate subcarrier groups when the subcarrier set corresponding to the first terminal device comprises three consecutive subcarriers of one resource block, and the subcarrier group corresponding to the first terminal device comprises two consecutive subcarriers in the subcarrier set, wherein a first candidate subcarrier group comprises a first subcarrier and a second subcarrier in the subcarrier set, and a second candidate subcarrier group comprises the second subcarrier and a third subcarrier in the subcarrier set; or
the first terminal device corresponds to four candidate subcarrier groups when the subcarrier set corresponding to the first terminal device comprises 12 consecutive subcarriers of one resource block, and the subcarrier group corresponding to the first terminal device comprises three consecutive subcarriers in the subcarrier set, wherein a first candidate subcarrier group comprises a first subcarrier to a third subcarrier in the subcarrier set, a second candidate subcarrier group comprises a fourth subcarrier to a sixth subcarrier in the subcarrier set, a third candidate subcarrier group comprises a seventh subcarrier to a ninth subcarrier in the subcarrier set, and a fourth candidate subcarrier group comprises a tenth subcarrier to a twelfth subcarrier in the subcarrier set.
