Abstract: This application provides an uplink information sending method, including: determining, based on a transmission direction of a transmission resource and a preset grant-free transmission resource, a grant-free transmission resource used for uplink transmission, where the transmission resource includes the grant-free transmission resource; and sending uplink information on the grant-free transmission resource used for uplink transmission. According to the method, the grant-free transmission resource used for uplink transmission may be a subset of the preset grant-free transmission resource or may be a resource determined based on a location of the preset grant-free transmission resource. In either case, the grant-free transmission resource used for uplink transmission belongs to the transmission resource whose transmission direction is uplink transmission direction.

Abstract: A system and method for multiplexing traffic. A wireless device such as a user equipment (UE) may receive a first signal over first resources assigned to carry a first downlink transmission from a base station, and receive a first downlink control indication (DCI) message from the base station. The first DCI message may include a pre-emption region (PR) indication and a PR bitmap, and the PR indication may indicate a location of a time-frequency region. The PR bitmap may include bits associated with different portions of the time-frequency region, and each of the bits in the PR bitmap may indicate whether a preemptive downlink transmission is present in the corresponding portion of the time-frequency region.

Abstract: In a data receiving method, a terminal receives first indication information, where the first indication information indicates a target frequency domain position. The terminal determines a first time-frequency resource based on a time domain position of a control resource set and the target frequency domain position, where a frequency domain position of the first time-frequency resource is the same as the target frequency domain position. The terminal receives data on a target time-frequency resource, where the target time-frequency resource includes a second time-frequency resource and a part of resources in the first time-frequency resource; or the target time-frequency resource includes a second time-frequency resource but does not include the first time-frequency resource, where N is a positive integer.
