Abstract: The present disclosure provides an information transmission method and device based on a sweeping block. The method includes: configuring part of or all symbols of a data transmission subframe within a sweeping period as a sweeping block; and carrying a sweeping signal channel in the sweeping block for transmission. The sweeping signal channel refers to a signal or a signal and channel to be transmitted by polling all ports or beams. The above solution can improve flexibility and efficiency of data beam transmission and reduce a latency of traffic transmission.

Abstract: Systems and methods for wireless communications are disclosed herein. In one implementation, a wireless communication device determines that at least a portion of a first uplink (UL) resource is canceled due to overlapping with an indicated resource indicated by an UL Cancelation Indication (UL CI) received from a base station. In one implementation, in response to determining that the at least the portion of the first UL resource is canceled due to overlapping with the indicated resource, a wireless communication device determines whether a second UL resource is used to transmit UL data.
