Abstract: This application provides an indication method, a network device, and user equipment. The network device explicitly or implicitly indicates, by using indication information (including but not limited to a bitmap, information indicating a quantity Wt, and information indicating an index) carried on one or more downlink transmission units, a reception response for one or more downlink transmission unit sets that needs to be received by the network device, that is, a reception response for one or more downlink transmission unit sets that needs to be sent by the UE to the network device, so that the UE can correctly send, on a correct uplink transmission unit, the reception response that is for the downlink transmission unit sets and that the network device indicates the UE to send. In this way, errors and unnecessary retransmission are reduced, quality of service is ensured, and communication efficiency is improved.

Abstract: Embodiments of this application disclose a resource allocation method and a related device and system. The method may include: allocating a resource group including M first resource blocks to a terminal when allocating uplink resources, where an occupancy ratio of a frequency spacing formed by the M first resource blocks to a system bandwidth is greater than a preset threshold, and the resource group further includes N second resource blocks in any frequency domain positions, where M≥2, N≥1, and both M and N are positive integers; and sending resource indication information to the terminal, where the resource indication information includes information about the resource group. According to the embodiments of this application, scheduling of uplink resources can be more flexible for use of an unlicensed frequency band while the OCB requirement of ETSI is met.

Abstract: An example terminal device receives resource scheduling information sent by a network device, where the resource scheduling information is used to indicate a second resource set allocated by the network device, where the second resource set includes at least one resource block which is from a first resource set, and where the first resource set is an integer quantity of resource blocks that are evenly distributed in frequency domain. The terminal device can then perform uplink transmission on a detected idle frequency domain resource based on the resource scheduling information, where the uplink transmission occupies a plurality of time units, where a resource structure of a resource block used for the uplink transmission in each time unit is the same as a resource structure of the second resource set, and where frequency locations of resource blocks used for the uplink transmission in adjacent time units are different.
