1. An information receiving method comprising:
receiving, by a terminal device, first configuration information from a network device, wherein the first configuration information carries precoding indication information of each resource unit of N resource units allocated to the terminal device, N≥1, and N is an integer; and
performing, by the terminal device, precoding processing on uplink data carried on each of the N resource units by a precoding matrix corresponding to the precoding indication information of each of the N resource units, based on the first configuration information;
wherein before the performing of the precoding processing on t e uplink data carried on each of the N resource units, the method further comprises:
determining, by the terminal device based on the precoding indication information of each of the N resource units and a correspondence between the precoding indication information and a first codebook set, the precoding matrix corresponding to each of the N resource units, wherein the first codebook set comprises at least one precoding matrix; and
wherein before the determining of the precoding matrix corresponding to each of the N resource units, the method further comprises:
receiving, by the terminal device, first signaling from the network device; and
determining, by the terminal device, a second codebook set based on the first signaling, wherein the second codebook set is a subset of the first codebook set; and
the determining of the precoding matrix corresponding to each of the N resource units comprises:
determining, by the terminal device from the second codebook set based on each piece of precoding indication information, the precoding matrix corresponding to each of the N resource units.
