Abstract: This application provides an information transmission method and apparatus. The information transmission method includes: a terminal device determines a target offset parameter, an uplink control channel resource index, a physical resource block offset parameter, and a number of initial cyclic shift indexes included in an initial cyclic shift index set. The terminal device determines, based on the target offset parameter, the uplink control channel resource index, the physical resource block offset parameter, and the number of initial cyclic shift indexes included in the initial cyclic shift index set, a resource block index for uplink control channel transmission. The terminal device sends uplink control information to a network device on a resource associated with the resource block index.

Abstract: Methods, apparatus, and systems for data or information transmission are provided. In one aspect, a data sending method by a terminal device includes: determining indication information, determining, based on the indication information, a transport block size (TBS) used to send data, and sending the data based on the determined TBS. The terminal device can determine at least two of first information indicating that the TBS is a first TBS, second information indicating that the TBS is a second TBS, or third information indicating the terminal device to select a TBS from a TBS set as a third TBS used by the terminal device to send data. The TBS set is determined based on the first TBS, and can include at least one of the second TBS or the third TBS. The indication information includes one of the at least two of the first, second, or third information.

Abstract: A terminal device receives downlink control information sent by a network device. The downlink control information includes a resource allocation field. The resource allocation field includes ⌈ log 2 ⌊ N RB UL 6 ⌋ ⌉ high-order bits and M low-order bits. When the resource allocation field is used to indicate an allocated subcarrier resource, K bit states in bit states of the M bits are used to indicate allocation of subcarrier resources, and a quantity of subcarriers indicated by each of the K bit states is less than 12. The terminal device determines, based on the resource allocation field, whether the resource block or the subcarrier resource is allocated. The terminal device sends information on the allocated resource block or the subcarrier resource. The method and the device provided in embodiments of the application can be applied to a communications system.

Abstract: This application provides an information processing method and a communications device. An information processing method includes: a first communications device receives first information from a second communications device. The first communications device determines, based on the first information, that a start location of a first time window is a K1th time unit after a start location of a first resource or the start location of the first time window is a K2th time unit after an end location of the first resource. The first resource is a resource used by the first communications device to transmit data, and K1 and K2 are positive integers. The first communications device monitors, based on the determined start location of the first time window, control information sent by the second communications device.
