Abstract: This application relates to a channel information feedback method, a channel information recovery method and an apparatus. In an example method, a terminal device receives a first reference signal from a network device. The terminal device obtains a first channel state matrix based on the first reference signal. The terminal device performs sampling on the first channel state matrix based on a first sparse pattern, to obtain a sparse channel state matrix, where the first sparse pattern is configured by the network device, and the first sparse pattern is used for performing sampling on at least one dimension of the first channel state matrix. The terminal device sends first channel information to the network device, where the first channel information indicates the sparse channel state matrix.

Abstract: A communication method includes receiving, by a first terminal device, first information sent by a second terminal device. The first information includes information indicating a second beam selected by the second terminal device. The communication method also includes sending, by the first terminal device, (1) identification information of the second terminal device, or (2) identification information and the first information, to a network device. The first terminal device is a cluster head node, and the second terminal device is a member node of a cluster to which the first terminal device belongs.

Abstract: An uplink data transmission method and an apparatus include or relate to a terminal device which determines, based on indication information of a network device, a time-frequency resource corresponding to a random access resource, or a part of a time frequency resource in the random access resource, to directly transmit uplink data. Configuration information of a time-frequency resource for random access may be reused for configuration information of the time-frequency resource, so that signaling overheads are reduced and a resource utilization is improved.

Abstract: A random access method and an apparatus. In the method, random access is completed in a manner in which an agent terminal performs access, so that an access requirement of a terminal can be satisfied under low energy consumption. The method and the apparatus may be applied to application scenarios such as an internet of things (IoT), machine type communication (MTC), massive machine type communication (mMTC), an internet of vehicles, and a connected vehicle.

Abstract: An uplink control information transmission method and apparatus. The method includes: determining, by a terminal device, a preamble that needs to be sent; determining, by the terminal device based on the preamble, a first resource set that is in a physical uplink shared channel resource and that is used to send uplink control information, where the PUSCH resource includes a plurality of resource sets; and sending, by the terminal device, the uplink control information and uplink data on the PUSCH resource, where the uplink control information is mapped to the first resource set, the uplink data is mapped to a resource that is other than the plurality of resource sets and that is in the PUSCH resource, and no information or uplink data is mapped to a resource set that is other than the first resource set and that is in the plurality of resource sets.
